[0003] The most common communication for thc general public can be called a
general wired
2 telephone using a public telephone network.
3 [000411 Additionally, home communication equipment whose mobile usage
is restricted to a
user's residence started to appear in Korea from the end of 1970's, which is
so-called a cordless
phone.
6 100051 This cordless phone has a usage frequency of 46/49Mhi
(megahertz), a common
7 indoor reachable distance of about 50m (meters), a channel gap of 25Khz
(kilohertz) and an FM
8 (Frequency-Modulation) modulation scheme. It commonly uses an MCA (Multi
Channel
9 Access) scheme which can be called a request channel scheme from the
middle of 1980's even
though a. fixed channel scheme was adopted in the earlier time.
ii 100061 A cordless phone of 900 Mhz bandwidth appeared taking an enhance
of speech quality
12 into account from the early 1990's_
13 [00071 The cordless phone which is modified to be used only in the
residence by making the
14 general phone operable in the wireless environment is called CT-1 (First
Generation Cordless
Phone).
16 10008,1 The CT-1 cannot be used in a public place since it was devised
for home usage. In
17 order to improve such a problem, an originating dedicated mobile phone,
so called CT-2 (Second
18 Generation Cordless Phone) system was suggested for the first time in
the United Kingdom in
19 1989 and adopted as a European standard in Europe. The CT-2 system is
currently serviced in
several countries and was serviced as a commercial service in Korea in the
early 1997.
21 [00091 . To directly express the property of the CT-2, it can be called
a wireless public
22 telephone for a pedestrian, which is used as the CT-1 at home and is
used as a public phone in a
2
CA 02457606 2009-05-04
public place which enables the user to make a speech within 200m from the
public telephone on
2 walking.
3 100101 A defect of the CT-2 is that there are no functions of call
forwarding and handover. A
4 CT-3 (Third Generation cordless Phone) appeared to supplement such a
defect.
[00111 The CT-3 can be stated by classifYing it into private and public
network dimensions in
6 accordance with its use, which can be explained centering around a PBX
(Private Branch
7 eXchange) system in the private network dimension.
100121 A communication system used for business in the existing building
generally uses the
9 PBX system and a system capable of mobile communication in a building by
making the PBX
system operable in a wireless environment is a wireless PBX which corresponds
to many
11 systems including a DECT (Digital European Cordless Telephone).
12 100131 The DECT system regarded as a representative of the CT-3 was adopted
as a European
13 standard by ETSI (European Telecommunications Standards Institute) on
March, 1992.
14 NON The main properties of this system are that its wireless connection is
performed in a
TDMA (Time-Division Multiple Access) scheme, its bandwidth is 2Ghz
(gigahertz), and a
16 channel bandwidth is 1.73Mhz so that each channel has 12 slots.
17 100151 On developing the CT-3 system into a public network dimension by
supplementing the
18 system functions such as a handover and a roaming, a Low Tier PCS (Personal
Communication
19 Service) appeared, which is a personal communication enabling a user to
make a speech
regardless of whenever, wherever and with whomever and being evolved from the
cordless
21 phone.
3
CA 02457606 2009-05-04
100161 The Low Tier PCS (Personal Communication Service) is a scheme by which
pedestrian
and indoor services can be provided on the basis of the cordless phone, such
as DECT in Europe,
3 PHS (Personal Hand-phone System) in Japan and PACS (Personal Access
Communication
4 Service) in. the United States.
[0017] On the other hand, there is a High Tier PCS (Personal Communication
Service)
6 corresponding to the Low Tier PCS (Personal Communication Service), which
becomes a micro
7 cell developed from analog cellular technology in order to provide a
service centered around a
vehicle including a pedestrian.
9 [0018] The analog cellular which becomes a basis of the High Tier PCS
(Personal
Communication Service) was developed by AMPS (Advanced Mobile Phone Service)
011
11 October, 1983 with the aid of Bell Lab., one of its property is that it
introduced a cell concept
12 wherein its channel bandwidth is 30kHz in 824 to 894MHz and its modulation
scheme is FM.
13 [0019] A system of the analog cellular mode is used as N.MT (Nordic Mobile
Telephone) and
14 TACS (Total Access Cellular System) in Europe and as NTT method in Japan.
[0020] However, as such systems experience the capacity limitation as mobile
communication
16 subscribers are abruptly increased in the end of 1980, communication
quality reduction due to
17 the increase, and various requests for service, a method appears to
improve the problems.
18 [0021] In order to improve the defects of the analog cellular such as a
low capacity, low
19 communication quality and limited data services, Korea developed
narrowband CDMA (Code-
Division Multiple Access) scheme .and made a commercial service from early
1996; and United
21 States standardized IS-95 CDMA on July, 1993 and also developed IS-54 TDMA
scheme.
4
CA 02457606 2009-05-04
1 =10022] Also, GSM (Group Special Mobile) scheme first started in Europe in
the end of 1992,
which commercially used the TDMA in a pan-European style and had a property
that it can be
3 connected to each nation of Europe.
4 100231 Japan commercialized a PDC (Public Digital Communication) scheme
using the
TDMA in early 1993.
6 [0024] However, such a digital cellular system does not seem to be a
reasonable price for the
7 public to have even though it seems to solve a quality of speech and a
capacity to some degree.
8 That is, the system does not seem to be improper for providing a general
service.
9 [00251 Accordingly, the High Tier PCS (Personal Communication Service)
seems to be
evolved to make the digital vehicle mobile phone system to be generalized
service and has merits
ii that it provides high speed mobility and simple network construction, and
can utilize the digital
12 cellular technology.
13 [0026] The High Tier PCS (Personal Communication Service) system includes
an Up-band IS-
14 95 CDMA scheme evolved from the IS-95 COMA and a DSC-1800 (Digital
Communication
System) scheme evolved from the GSM.
16 100211 Though the development of PCS (Personal Communication Service)
system can be
17 divided into the High Tier PCS (Personal Communication. Service) and Low
Tier PCS (Personal
s Communication Service) as stated above, the High Tier scheme is recently
being modified to
19 accept thc Low Tier scheme, and vice versa, so that the schemes are on a
trend that they are
integrated into an IMT-2000 (FPLMTS, Future Public Land Mobile
Telecommunication System).
21 [0028] A communication network of the IMT-2000 is a network integrating
wired and
=y2 wireless communication services to be interconnected mutually, wherein
many experts expect
5
CA 02457606 2009-05-04
1 that an activation of a wireless Internet having the same transmission
speed as that of a wired
Internet can be visualized by constructing a network which can provide a low
speed data
3 transmission (I4.4kbps (kilobits per second)) being a wireless
environment and a high speed data
4 transmission (384kbps). [0029] Recently, various wired and wireless
integration systems are
being developed, which enable the wired and wireless integration service to be
performed by
6 integrating a wired network such as a public phone network and a wireless
network such as a
mobile communication network which have been already constructed as a post-
stage of the DAT-
2000.
9 [0030] Also, a mobile terminal (hereinafter, referrcd as a complex
wireless terminal since it
provides a plural band service and a. plural mode service with a mobile
terminal) supporting the
ii plural band and plural mode is under the development in view of the
mobile terminal. For
12 example, there is a mobile terminal having dual band/dual mode which can
provide a function of
13 the mobile phone and a function of the mobile communication
simultaneously.
14 [00311 The mobile terminal of the dual band/dual mode simultaneously
providing the
fbnctions of wireless phone and mobile communication is called a dual
bandwidth terminal since
16 it can support both a frequency band used in wireless phone and a
frequency band used in a
17 mobile communication, and a dual mode terminal since it can support both
a wireless phone
18 Mode and a mobile communication mode.
19 100321 Besides them, there are a PCS/AMPS typed mobile terminal as the
dual mode mobile
70 terminal and a GSM900/GSM1800 as the dual band mobile terminal.
21 [00331 Such a plural band/plural mode mobile terminal can be
operated in both single
22 band/single mode and dual band/dual mode by a user's manual operation.
Of course, it is
6
CA 02457606 2009-05-04
possible to maintain a connection to a communication network which can
guarantee a higher
2 quality of speech in the case that there is transferred from a
communication network to another
3 communication network automatically.
4 [0034J Recently, there has been remarkably developed technology related
to a wireless
communication network and suggested many technology standards. Among them,
Bluetooth
technology standard and wireless LAN (Local Area Network) field are technology
standards
7 being spotlighted, which are closely related with the mobile terminal and
produce a development
of the mobile terminal of the plural band/plural mode.
9 [0035] However, a conventional method using the complex wireless terminal
having the plural
band/plural mode has a problem that when a network failed to receive a call a
receiver has to
i retry a call establishment to another network since the networks were
separated.
12 [0036] Therefore, services in a shadowed area, a basement and in-house
arc sometimes
13 deteriorated in the cases of CDMA, GSM and WCDMA (Wideband Code Division
Multiple
14 Access) which provide broadband service areas so that repeaters should be
installed for those
places with separate expenses.
16 [0037] Though the communication systems such as WLAN and BLUETOOTH
providing
17 services in narrow areas can provide a good quality of services with low
expenses, their service
Is areas are not wide and their mobility is limited so that it is necessary
to develop technology for
19 enlargement of service area and guarantee of mobility.
[0038] Also, there is a problem that when a user of the complex wireless
terminal having the
21 plural band/plural mode moves from a general public phone network to a
mobile communication
22 network during making a call, or from the mobile communication network to
the general public
7
CA 02457606 2009-05-04
1 phone network, a speech is disconnected since a handoff is not provided
between the two
2 networks.

establishes a communication line when a call response message is received from
the incoming
side after transmitting the call setup message (step S112).
3 [01501 Next, after monitoring whether the complex wireless terminal moves
to the extension
4 wireless network service area (step S114), when it does not move to the
extension wireless
network service network, the call is released as the call is completed (steps
S116 and S118).
6 Whcn the call is not completed (step S116), then there is monitoring of
whether the complex
wireless terminal moves to the extension wireless network service area (step
S114) again.
8 [01511 However, when the complex wireless terminal moves to the
extension wireless
9 netwOrk service area, the mobile switching center and the incoming
terminal maintain the
communication line (step S120), and when the call is completed (step S122),
the call is released
11 (step S124) and then the location of the complex wireless terminal is
registered in the home
12 location register (step S126). If the call is not completed (step S122),
then the mobile switching
Is center and the incoming terminal maintain the communication line again
(step S120).

9 [01561 However, in the case that the complex wireless terminal moved
to the mobile
communication network service area, the mobile switching center performs a
location
11 registration for the complex wireless terminal and then the wired and
wireless complex gateway
12 disconnects the call (step S220), and the mobile communication network
establishes the call
13 using the base station controller and the base station transceiver
subsystem (step S222). Next,
14 until the call is completed, the call is released (steps S224 and S226).
101571 Here, even though a case that the incoming side is a subscriber of
the mobile
16 communication network has been explained, a case that the incoming side
is a public phone
17 network subscriber can be embodied in the same manner.

through the base
switching center and the base station transceiver subsystem when the mobile
switching center is
3 located in the mobile communication network service area (step S316). At
this time, when the
4 complex wireless terminal is busy, the mobile switching center transmits
a busy message to the
incoming side and informs the incoming side that the complex wireless terminal
is busy.
6 101601 Next, after monitoring whether the complex wireless terminal
moves to the extension
7 wireless network service area (step S318), the call is released when the
call is completed in the
8 state that the complex wireless terminal did not move to the area (steps
S328 and S330). If the
9 call is not completed (step S328), then there is still a monitoring of
the complex wireless
terminal moves to the extension wireless network service area (step S318).
101611 In addition, in the case that thc complex wireless terminal moves
to the extension
12 wireless network service area, the mobile switching center also
maintains the call passing

101641 In the case that the complex wireless terminal is located in the
extension wireless
9 network service area (step S336), the call is released when the call is
completed (steps S344 and
S346). Otherwise, if the call is not completed (step S344), there is still a
determination of
11 whether a complex wireless terminal is moved to the mobile communication
network service
12 area or is still located in the extension wireless network service area
(step S336).

the complex wired and
wireless gateway 120 through the AP 121.
16 [0176) Since the wired and wireless complex gateway 120 transmits the
data request signal
17 requested through the AP 121 to the PDSN/FA 180 and can be connected to
the Internet through
Is the PDSN 180, it is possible to provide a data service wished (chosen) by
a user.
19 101771 Also, the HA 181 manages a plurality of Ms, and maintains the
mobile IP to make it
possible that the data service is serviced without any communication
disconnection even in the
21 moved service area when the complex wireless terminals 110, 111 and 112
move to other service
?I? areas.
48
CA 02457606 2009-05-04
1 [01781 Since the information on the location of the terminal is managed
in the HLR 170 even
2 in the case of the data service of the complex wireless terminals 110,
111 and 112 according to
3 the construction as described above, the location registration is
performed in the same manner as
4 the location registration process of the complex wireless terminals 110,
111 and 112 as described
above.
6 101791 Also, when a data service is requested in the complex wireless
terminals 110, 111 and
7 112 in the premises, both an Internet connection through an extension
Intranet and a connection
8 through a public network PDSN 180 are possible. The PDSN is
interconnected to the wired and
9 wireless complex gateway 120 as well as the BSC 150.
[0180] in the case of a data service incoming in the complex wireless
terminals 110, 111 and
11 112, the incoming request of current location of the corresponding
terminal is made to the
12 corresponding BTS 160 or the wired and wireless complex gateway 120
obtained through the
13 MLR 170 and VLR by managing a mobile IP assigned in the HA/FA 181 and
180. That is, in the
14 case that the corresponding terminal is currently located in the
premises, the incoming request
1.5 signal is requested to the wired and wireless complex gateway 120, and
in the case that the
16 corresponding terminal is located in the public network, the incoming
request signal is provided
17 to the BTS 160,
13 101811 Also, in the case of the data service, when the complex wireless
terminal is handed-off,
19 mobility of the terminal to which a mobile IP is assigned is guaranteed
and the terminal is
serviced through the same PDSN. In the case of the terminal to which the data
service is
21 provided through the Intranet, when it moves out of the premises, it
cannot be provided with the
22 extension data service.
49
CA 02457606 2009-05-04
1 101821 In the course of receiving the data service in the premises, when
the wireless terminal
2 is out of the service area of the extension network, the HLR 170 and VLR
change the location
3 registration of the corresponding terminal, and the FA/HA is assigned
another mobile IP of the
4 corresponding terminal.
101831 Accordingly, the HA 181 can provide the data service to the
corresponding wireless
terminal without any data service interference using a tunneling method, that
is, by tunneling the
7 data received through the mobile IP registered in the first extension
network to a mobile IP
8 newly registered through a location movement to the public network.
9 . 101841 On the other hand, the functions of IF assignment and data handoff
using the mobile IP
are performed as follows.
11 [01851 All mobile agents regularly broadcast an Agent Advertisement
message being an
12 enlarged Router Advertisement message in order to make their mobile
supports known. The
13 mobile node receiving such a message can determine whether it is located
in the home nctwork
14 or moved to a new external network using information in the message.
101861 Representative methods to determine the movement of the mobile node
include LCS
16 (Lazy Cell Switching) and ECS (Eager Cell Switching).
17 [0187] In the case of the LCS, when it does not receive an agent
advertisement message for
18 the network where the LCS is currently located, the LCS determines that
it is out of the current
19 network and a registration process for a new location is performed. On
the other hand, in the
case of the ECS, when it receives an agent advertisement message from an
external agent in a
21 new network not being the current network even at once, it is determined
as the ECS has moved
22 to a new nehvork. Accordingly, the ECS has a merit that its delay of
movement determination is
50
CA 02457606 2009-05-04
shorter than that of the LCS, whereas it has a defect that its accuracy of
mobile determination is
2 not guaranteed and an effect caused by a mobile pattern of the node is
more than that of the LCS.
3 [0188] When it is recognized that the mobile node moved to the external
network, it is
4 possible to obtain a new COA, the COA being an IP address of the external
agent obtained from
the agent advertisement message (FA COA: Foreign Agent Care-of Address) or a
temporary IP
6 address obtained through the DHCP (Dynamic Host Configuration Protocol)
(CCOA : Colocated
7 Care-of Address). In the case of the CCOA, since an end point of the
tunnel becomes a mobile
8 node, an external header is additionally transmitted through thc wireless
channel so that the
9 paelcdpverhead becomes larger than the FA COA. Therefore, it is more
effective to use the FA
COA than the CCOA in the wireless environment.
11 101891 FIG. 10 is a view showing a process of registration between a
mobile node that has
12 moved to an external network and HA.
13 [01901 As shown in FIG. 10, the mobile node transmits a registration
request message to the
14 HA in order to establish the home address and a mobile binding of the
COA and receives a
registration reply message in response to the transmission. Such a
registration message includes
a home address of the mobile node, COA, a life time and information used to
authenticate
17 between the HA and the mobile node mutually.
18 10191] Binding Information of the mobile nodes managed by the HA should
be periodically
19 updated by the mobile nodes within the registration maintaining period
and its mobility should
be maintained.
21 [01921 After the registration to the HA has been completed, the packets
directed to the mobile
22 node are tunneled to the COA by the HA which performs the proxy ARP in
the home networt.
51
CA 02457606 2009-05-04
1 The packet sent by the mobile node is transmitted to the other party's
node through normal IP
2 routing and does not have to pass through the FA necessarily.
3 101931 FIG. 11 is a view showing a process of packet transmission to a
mobile node located in
4 an external network from the other party's node.
[0194] As shown. in FIG. 11, when the HA performs a tunneling to transfer the
packets to
6 COA of the mobile node, encapsulation methods such as an IP-in-IP
encapsulation, a minimal
7 encapsulation and a GRE (Generic Record Encapsulation) are used. The
packet transferred to a
destination of the tunnel through the tunneling is de-capsulated and thcn
transferred to the mobile
9 node. In the case that the destination of the tunnel is the FA, the
packet is de-capsulated by the
FA and is transferred to the mobile node in the general IP forwarding process.
Additionally, in
11 the case that the destination of the tunnel is the mobile node, the
packet transferred through the
12 tunnel is de-capsulated by the mobile node and transferred to an upper
hierarchy. Here, FIG. 12
13 is a view showing a process of the IP-in-IP encapsulation for the IP
packet.
14 [01951 The construction of the embodiment as described above is a case
that the complex
wireless terminals 110, 111 and 112 have both phone numbers used in the wired
network and in
16 the wireless network.
17 [01961 It is because the HLR 170 used for the terminal authentication
and location registration
Is is separately embodied in the wired network and the wireless mobile
network_ In the case that
19 the complex wireless terminals 110, 11 l and 112 receive a call from an
external source, it
becomes difficult to receive the call through a cheaper network since a caller
may not recognize
21 the location of the called. If the HLR of the wireless network and the
HLR of the wired network
2.2 precisely recognize the location of the terminal through an information
exchange in order to
52
CA 02457606 2009-05-04
solve the problem, it can be possible to receive the call through a phone
number exchange
7 mutually.
3 101971 It means that the phone numbers of the complex wireless terminals
110, 111 and 112
4 are defined as a number, and the caller may memorize one number. Also,
there is a method
where a service provider of the wired network may share the HLR with a service
provider of the
6 wireless network.
7 [0198] Hereinafter, another embodiment of a complex wireless service
apparatus using a
8 wired and wireless communication system and a method thereof in accordance

IP HLR 360, and a
is mobile gateway 310. Here, the mobile gateway 310 can be applied only to
the office zone
19 complex wireless service apparatus. That is, the mobile gateway 310
manages a plurality of APs
(API ¨ APn) since there arc a plurality of subscribers in the office zone, and
can be applied only
2 1 to the office zone complex wireless service apparatus in order to perform
a handoff between the
22 APs.
53
CA 02457606 2009-05-04
1 [0201] The access gateway 320 is an IP-DSLAM equipment, which provides a
ultra high
speed data service in a subscriber side, provides a data service by
interconnecting to the data

APs. Also, the mobile
gateway 310 is interconnected to the extension public private exchange 330.
11 [0204] As shown in FIG. 13, the public private exchange 330 located in the
office zone
12 complex wireless service apparatus is an exchange system, which is
generally used when a
plurality of extension users wish to use limited office line effectively.
14 102051 The extension of the public extension exchange 330 is consisted of
an analog linc and a
digital line, which recently provides a wireless solution such as PWT, WDCT,
DECT, etc., with
16 solutions which uses WLAN, BLUETOOTH, etc.
17 102061 Also, the analog line and digital line are used as the office line,
and especially the
18 digital line is of various kinds. For example, the digital line includes
BR1 (Basic Rate Interface),
19 PR! (Primary Rate Interface), xDSL (x Digital Subscriber Line), 10/100
LAN, etc.
[0207] The access gateway 320 shown in FIGS. 13 and 14 is a DSL subscriber
concentrator,
21 wherein a splitter is located in a subscriber side. The access gateway 320
provides the softswitch
22 /media gateway 350 with data received through the DSL.
54
CA 02457606 2009-05-04
102081 The public toll exchange 340 connected to the public extension exchange
330 through.
PSTN (Public Switched Telephone Network) line is a general public exchange,
which is
3 connected to a plurality of public extension exchanges to be managed
integrally.
4 102091 On the other hand, the BTS 400 in the public network is wirelessly
matched with a
complex wireless terminal (e.g., 301 and 300) to provide the mobile subscriber
with a mobile
6 communication service and to provide voice and data transmitted from the
complex wireless
7 terminal to the BSC 390.
8 102101 The BTS 400 performs functions of constructing a wireless
communication line
9 together with the complex wireless terminal included in the communication
service area, that is,
cell area and managing the wireless resources.
11 [02111 The MSC 370 is a system performing a function of exchanging hi

performed in the HLRs 360 and
12 380. Here, representative subscriber information includes current
location information of a
i3 terminal, roaming information. Moreover, whether a local network
service for "one phone
14 service" is supported, whether a local network location is inside or
outside, information on a
local network usage state, and the public phone number and wireless terminal
unique number are
16 made as the database.
56
CA 02457606 2009-05-04
102151 The softswitch/media gateway 350 performs the voice and data exchange
between a
wired network, and wired voice network and wireless data network. The case of
using the
3 gateway is used to perform a roaming service between different networks or
to perform a call
4 transfer to other networks for a call received by the user.
[0216] The complex wireless service method using the complex wireless service
apparatus
6 using the wired and wireless communication system constructed as described
above will be
7 explained in detail with reference to the accompanying drawings.
[0217] Firstly, a processing operation of an outgoing call from the complex
wireless terminal
9 300 will be explained.
[0218] At first, when a call is originated from the complex wireless terminal
300 registered in
11 the AP 303 in office or home areas, the call is connected to the PSTN
network by way of the AP
12 303 which supports a connection of a narrowband wireless network (WLAN,
BLUETOOTH,
13 UWB) rather than the broadband wireless service usage.
[0219] A PIN code is set between the complex wireless terminal 300 and AP 303
used here so
that only assigned terminal can be connected to the AP 303.
16 10220] Also, the AP 303 recognizes a digit received from the complex
wireless terminal 300,
17 and determines whether it is an extension communication in the AP 303 or
an office line
is communication and processes the determined communication.
19 [02211 In the case that the PSTN circuit is already occupied and it is
not possible to make a
communication when a call originating of the complex wireless terminal 300 is
tried, a VoIP call
21 is serviced through a data line connected to the AP 303. Of course, in
the case that the AP 303 is
57
CA 02457606 2009-05-04
1 not connected to the data line, the call is serviced through an external
network (CDMAõ GSM,
GPRS, WCDMA, ..).
3 [0222] Hereinafter, the functions described above will be explained in
detail with reference to
4 the accompanying drawings.
[0223] At first, a call setup is requested from the complex wireless terminal
300 to the AP 303,
6 the AP performs a call service establishment process 'wing a narrowband
air protocol, and
7 resource confirmation for the call and an authentication for the terminal.
102241 Moreover, in the case that the user transmitted a phone number for the
wired line, that
9 is, a phone number including an area code (for example, 031-****-****) to
the AP 303 or the
public extension exchange 330 through the complex wireless terminal 300, the
AP 303 or public
11 extension exchange 330 determines whether the phone number transmitted
from the Complex
12 wireless terminal includes the area code.
13 102251 As a result of the determination, in the case that the digit
transmitted from the complex
14 wireless terminal includes the area code, the corresponding area code is
detached, and the only
15digit for a pure phone number of the other party can be transmitted to the
public toll exchange
16 340 through the PSTN line.
17 [0226] Then, incoming and outgoing operations of the complex wireless
terminal will be
Is explained with reference to FIG. 13.
19 [02271 FIG. 16 is a view showing incoming and outgoing flows of a call
signal of the complex
wireless terminal in the complex wireless service apparatus shown in FIG. 14.
21 [0228) As shown in FTC. 16, when a wireless network of the complex
wireless terminal makes
22 a call, an IP is assigned.
58
CA 02457606 2009-05-04
1 [0229] In the case that there is an incoming from the MSC 370, when a
mobile network
2 number (for example, mobile communication number of 010-123-4567) is
received, the MSC
3 370 provides the BSC 390 with a call incoming signal, and the BSC 390
transmits the call signal
4 to a wireless terminal corresponding to the network number through the BTS
400 to form a call
channel.
6 [0230] On the other hand, in the casc that there is a call incoming to the
MSC 370 with the
7 wireless network number (999-1234), the MSC 370 provides the
softswitch/media gateway 350
with the call signal.
9 [0231] The softswitchtmedia gateway 350 recognizes current location of the
complex wireless
terminal having the corresponding wireless network number by searching for the
IP-HLR 360.
11 In the case that the complex wireless terminal having the corresponding
wireless network
17. number is located in the office/home zone, it provides the access gateway
320 with the
13 corresponding call signal, and the access gateway 320 provides the access
point with the
14 corresponding call signal to connect the call to the corresponding complex
wireless terminal. At
this time, the VoIP communication is performed between the softswitch/media
gateway 350 and
16 the access gateway 320, and the IP communication is performed between the
access gateway
17 320and the access point.
18 [02321 Also, voice data transmitted from the softswitch/media gateway 350
to the access
19 gateway 320 is PCM data, and the access gateway 320 transforms the voice
PCM data received
from the softswitch/media gateway 350 into thc IP data and provides the access
point 303 with
21 the IP data. As a result, the access gateway 320 transforms the voice
signal provided from the
59
CA 02457606 2009-05-04
1 wireless terminal into the PCM data in the state that the call is
connected between terminals, or
2 the PCM data into the IP data.
3 [0233] On the other hand, an incoming call received from the toll exchange
340 is transmitted
4 to the access point 303 through the softswitch/media gateway 350 and the
access gateway 320 in
the same method as the operation described above.
6 102341 On the other hand, a process of processing the incoming call will
be explained in the
7 case that the incoming call was received from the PSTN network/data
network to the AP.
8 (02351 At first, when the incoming call transmitted from the PSTN line or
data network is
received at the AP, the AP makes a call to a wired phone connected to the AP
(SLT (Single Line
Telephone) using the PSTN Line or the Vol? using the data line) and dual mode
wireless
11 terminals which support a narrowband, and makes all terminals to perform
a simultaneous
12 ringing operation for the incoming call.
13 [0236] In the case that the wired phone connected to the AP extension
network or one of the
14 dual mode wireless terminals (One-phones) made a response, the response
signal of the
corresponding terminal is transmitted to the PSTN or data network. At this
time, the AP
16 removes the. call of the remaining terminal except for the terminal that
has made the response and
17 ends the ringing operation, and performs a call service connection
between the terminal that has
18 made the incoming response and the outgoing terminal.
19 102371 The AP or exchange supporting the narrowband wired network service
provides a CID
(Caller ID (identification)) with an incoming assignment function, and
confirms so-called CID to
21 Onephone DB when an incoming call is requested from the office line and
makes an initial
22 incoming call only to the found Onephone terminal. Then, when there is no
response for a
60
=
CA 02457606 2009-05-04
1 predetermined time, the AP or exchange enables other terminals to make a
service of the
incoming call.
3 10238] A process of performing a call service to a specific terminal
using such as CID will be
4 explained.
10239] At first, an incoming of a specific complex wireless terminal (referred
to as Onephone
6 terminal, hereinafter) for the received CID is assigned in the database
within, the AP or private
7 exchange.
8 [0240] After the specific Onephone terminal incoming for the CID is
assigned, when the
9 incoming call is received from the PSTN/data network, the AP or private
exchange determines
whether the received incoming includes the CID. When the received incoming
includes the CID,
the incoming Onephone terminal assigned to the database of the AP or private
exchange is
12 searched for.
13 [0241] In the case that there exists the One-phone terminal
corresponding to the CID for the
received incoming call, the corresponding Onephone terminal is called.
[0242] In the case that there is a call response from the called Onephone
terminal, the AP or
16 private exchange mutually connects the call between terminals and
provides a communication
17 service.
IS [0243] That is, when the incoming call is received from the PSTN/data
network, the AP or
19 private exchange determines whether the received incoming call includes
the CID.
102441 As a result of the determination, in the case that the received
incoming call includes the
21 CID, the incoming Onephone terminal assigned to the database of the AP
or private exchange is
61
CA 02457606 2009-05-04
1 searched for, and it is determined whether there is the incoming
assignment terminal, that is,
whether there exists the incoming assignment CID.
3 102451 As a result of the determination, in the case that there exists
the incoming assignment
4 Onephone terminal, it is determined whether the corresponding Onephone
terminal is located in
an Onephone service area. In the case that the corresponding Onephone terminal
is located in
6 the Onephone service area, the incoming call service is requested to the
incoming assigned
7 Onephone terminal.
8 [02461 In thc case that there is a call service response from the
corresponding Onephone
9 terminal assigned for incoming when the incoming call service is
requested, the call is connected
between terminals to perform the communication service.
10247J On the other hand, in the case that there does not exist the incoming
assignment
12 Onephone terminal in the database within the AP or private exchange, the
incoming assigned
13 corresponding Onephone terminal is not located in the Onephone service
area, and there is no
14 call service response from thc corresponding incoming assigned Oncphone
terminal, the
incoming call service for all terminals connected to the AP is requested. That
is, in the case that
16 all terminals connected to the AP are called and there is a service
response from one of the
17 terminals, a communication with the corresponding terminal is made.
[02481, In the case that there is no response from all terminals connected to
the AP for the call
19 coming from the office line through the wired line (PSTN or Data service
network), after CID
received at an incoming assigned Onephone terminal which was assigned
previously is analyzed,
21 information on the incoming call is transferred with an SMS message or a
call transfer service to
22 an assigned terminal is perfbrmed. Such a process will be explained,
hereinafter.
62
CA 02457606 2009-05-04
1 WM] At first, the SMS service is assigned to a specific Onephone
terminal for the received
2 CID in the database within the AP or exchange. That is, in thc case that
a call service is
3 requested to a eel-responding specific terminal in the state that the
call service is assigned to a
4 specific terminal for the received CID, when there is no call service
response of the terminal, the
SMS service for transmitting the SMS message to the corresponding specific
terminal is assigned.
6 102501 In the state that the SMS service is assigned to a specific
terminal, when the incoming
7 call is received through the PSTN or data network, the AP or private
exchange determines
8 whether the received incoming call includes the .CID.
9 [0251) A.s a result of the determination, in the case that the
corresponding incoming call
includes the CID, it is searched from the database whether there exists the
incoming assigned
Onephone terminal for the corresponding CID.
12 [0252] In the case that there exists the incoming assigned Onephone
terminal, the incoming
13 call is requested at the corresponding Onephone terminal.
14 102531 In the case that there is no response of the assigned terminal
according to the incoming
call, all terminals connected to the AP are called.
16 [02541 As a result of the call, in the case that there is no response
to the call from all the
17 terminals, the SMS message including the CID is transmitted to the SMS
assigned Onephone
Is terminal and the SMS message including the CID is transmitted to the
other party terminal
19 through the PSTN or data network.
02551 On the other hand, after the SMS message is transmitted, a call
transfer service to the
2I assigned terminal is performed, whose process will be explained,
hereinafter.
63
CA 02457606 2009-05-04
1 = [0256] A call transfer service is assigned to a specific Onephone for
the received CID in the
database within the AP OT private exchange.
3 [02571 In the state that the call transfer service is assigned to a
specific terminal, when an
4 incoming call is received through the PSTN or data network, the AP or
private exchange
determines that the received incoming call includes the CID.
6 [0258] As a result of the determination, in the case that the
corresponding incoming call
7 includes the CID, it is searched from the database whether there exists
the incoming assigned
8 Onephone terminal for the con-esponding CID.
9 [0259] In the case that there exists the incoming assigned Onephone
terminal, the incoming
call is requested at the corresponding Onephone terminal.
11 102601 Tn the case that there is no response of the assigned terminal
according to the incoming
12 call request, all terminals connected to the AP are called.
13 [0261] As a result of the call, in the case that there is no response to
the call from all terminals,
14 the SMS message including the CID is transmitted to the SMS assigned
Onephone terminal, and
the SMS message including the CID is transmitted to the other party terminal
through the :PSTN
16 or data network.
17 102621 Also, the AP or private exchange requests the call transfer
service including the
s assigned specific Onephone terminal information to the public exchange.
Accordingly, the
19 public exchange transfers the call to the specific terminal for the call
transfer service assigned to
the database within the AP or private exchange and performs the call incoming
request using the
21 transferred terminal_
64
CA 02457606 2009-05-04
[02631 Hereinafter, a method for processing a call received from the external
network (GSM,
2 CDMA,...) during communication (both of outgoing and incoming) for the
PSTN or wired VoIP
3 call through the Onephone terminal will be explained.
4 [0264) At first, in the case that there is an incoming call service
request through the PSTN or
data network, the AP or private exchange requests the incoming call for the
Onephone terminal
6 and the Onephone terminal informs the user that the incoming call was
received.
7 [0265) Accordingly, the user hooks-off the Onephone terminal, and the
Onephone terminal
transmits the response sictnal for the incoming call to the AP according to
the user's hook-off.
9 10266) The AP transmits the incoming call service response signal to
the PSTN or data
network (public exchange) according .to the incoming response signal
transmitted from the
11 Onephone terminal.
12 10267) Accordingly, a communication for the incoming call with the
Onephone terminal is
13 made through the PSTN or data network.
14 [02681 In the case that there is an incoming call service request to
the Onephone ten-ninal
through a broadband network while the communication is made through the
PSTN/data network,
15 the Onephone terminal informs the user of th.e incoming call information
in order that the user
17 can select whether he or she receives the incoming call from the
broadband network by
is displaying the broadband network incoming call service request as a beep
or message.
19 [0269] In the case that the user selects an arbitrary key to receive
the incoming call from the
broadband network, that is, the user responds to the incoming call from the
broadband network,
71 the Onephone terminal requests a Hold of the previous call, that is, a
call which is operating
22 through the PSTN or data network to the AP.
65
CA 02457606 2009-05-04
1 [0270] Accordingly, the AP holds the previous call according to a hold
signal to the previous
2 call which is transmitted from the Oncphone terminal, and informs the PSTN
or data network of
3 the hold of the previous call.
[02711 The Onephone terminal performs a communication with the other party
terminal
through the broadband network by transmitting a response signal for the
incoming call
6 transmitted from the broadband network.
[0272] After all, when an incoming call occurs from the external network, the
terminal itself
8 informs the user of an occurrence of the incoming call through the beep or
message.
9 102731 In the case that the user who has received an incoming call
occurrence message pushes
a communication button, it is possible to hold an existing call and to respond
to a call from the
11 external network. At this time, the user can release the existing call (a
call through a wired line)
12 or hold the call. That is, it can be a selection matter or fixed matter
of the terminal usage.
13 [0274] Otherwise, a specific key (button) can be prepared, which can
remove the existing call
14 and service the call from the external wireless network, and a specific
key (button) can be
prepared, which acts to disregard a service for a new call.
16 [0275] Then, a hand off process between networks when the Ortephone
terminal (a complex
17 wireless terminal) moves to another service area (coverage) will be
explained with reference to
IS FIG. 17.
19 102761 FIG. 17 is a view showing a signal flow for a handoff process of a
complex wireless
terminal in the complex wireless service apparatus shown in FIG. 14.
21 [0277] Firstly, as shown in FIG. 17, when the complex wireless terminal
300 moves from a
wireless network, that is, a private network of the oftice/home to a mobile
network while it
66
CA 02457606 2009-05-04
=
1 provides a voice communication or data service, the AP 303 senses the
strength of the pilot
signal of the complex wireless terminal 300 and recognizes location movement
of the complex
3 wireless terminal.
4 102781 Also, when the complex wireless terminal 300 moves from the mobile
network to the
private network of the office/home while it receives the voice and data
service, the AP 303
6 senses the strength of the pilot signal of the complex wireless terminal
300. Moreover, as a
7 result of the sense, in the case that it is determined that the complex
wireless terminal 300 moved
8 to the service area of the private wireless network, the handoff request
signal is transmitted to the
9 softswitch/rnedia gateway 350 through the access gateway 320.
[0279j Accordingly, when the softswitch/media gateway 350 requests the call
release of the
11 mobile network to the MSC 370 to release the call of the complex
wireless terminal 300 to the
12 mobile network, a handoff to the private network is made so that the
voice and data service can
13 be provided from the private network.
14 [0280] Here, a call which does not pass through the softswitch/rnedia
gateway 350 is not
handed off between heterogeneous terminals of the complex wireless terminal.
In this case, the
16 call is not disconnected and the service is continuously provided
through the mobile network.
17 [028i] On the other hand, when the complex wireless terminal moves from
the private
IS network to the mobile network and then moves to another service area of
the private wireless
19 network, that is, when the complex wireless terminal moves from a
service area A of the private
wireless network to the mobile network and then moves to a service area B of
the private
21 wireless network, since the IP-HLR 360 recognizes information on the
location of the terminal, it
27 is possible to perform a handoff through the softswitch/media gateway
350.
67
CA 02457606 2009-05-04
1 102821 More detailed explanation will be given for such a handoff
process.
[02831 A call service operation in the case that the Onephone terminal moves
from one service
3 area to another service area, for example, from a narrowband service area
to a broadband service
4 area will be explained.
[0284] The case that the Onephone terminal is out of the narrowband coverage
occurs when an
RSSI (Radio Signal Strength Indication) level of a pilot (Pilot or Sync.),
channel of the
7 narrowband service is lowered, or a data error rate is increased. Whether
the Onephone terminal
8 is out of the narrowband service area is determined by assigning proper
threshold values to each
9 of the service coverage in each of the above cases.
[0285] For example, the area where the Onephone terminal can be located can be
divided into
11 an area where it has high RSSI values to the extent that scanning is not
needed, an area where an
12 RSSI level of the terminal is scanned, and an area where the Onephone
terminal starts to get out
13 of the narrowband. That is, in the case that the area has RSSI value
more than a first reference
14 value, the Onephone is determined to be in the corresponding area since
the strength of the pilot
signal is high, and in the case that the area has an RSSI value less than a
second reference value,
16 the corresponding Onephone terminal is determined to be out of the
corresponding area since the
17 error rate value is very high. Also, in the case that the area has RSSI
value between the first
IS reference value and the second reference value, it is determined that
the Onephone is on the way
19 out of the corresponding area so that it is confirmed whether the
Onephonc is out of the coverage
by continuously performing a scanning operation of the Onephone.
21 [02,i6} In the case that a current call of the Onephonc terminal is a
voice call when the
22 Onephone terminal moves to another coverage, the user is notified of the
coverage breakaway
68
CA 02457606 2009-05-04
1 (movement) situation using a voice signal (voice message, beep, melody,
...). Additionally, in
the case that a cm-rent call of the Onephone terminal is a data call (in the
case of receiving a data
3 call) when the Onephone terminal moves to another coverage, the user is
notified of the situation
4 by displaying message or pictogram on the LCD (Liquid Crystal Display) of
the Oncphone
terminal to indicate the coverage breakaway of the Onephone terminal. Of
course, an integrated
6 notification method can be used for each of the voice and data calls.
7 [02871 A. mode transfer operation in the case of coverage movement of
Onephone terminal
8 will be explained.
9 [0288] In the case that the Onephone moved from an external network to the
AP in the narrow
band service area, automatic mode transfer of the terminal is performed by
means of a searching
through periodic shun] transfer from the AP to the Onephone terminal, or usage
mode transfer
12 (narrow band service or broad band service) can be requested by notifying
it to the Onephone
13 terminal.
14 [02891 In the case that the Onephone terminal moved from the AP to the
external network
(broad band network), when the Onephone terminal cannot receive any signal
from the AP, the
16 network operates in an external network connection mode. At this time, an
operation to
17 periodically search for whether there is a signal from the AP is
performed.
18 [02901 At this time, the case that the Onephone terminal moves to the
external network occurs
19 when the SiF.r.110.1 strength of the AP of the- narrowband network is
lowered, or the signal or data
error rate is increased while the signal strength of the AP is lowered, as
described above. They
21 can be obtained in the Onephone terminal and AP according to the method
provided in each of
22 the narrowband protocol. When thc Onephone terminal gets out of the
threshold value of the
69
CA 02457606 2009-05-04
1 RSS1 and error rate for the service area which was previously assigned,
the Onephone terminal is
determined to be out of the narrowband service area. Data received from the AP
in such a
3 threshold value is determined as data which is not normally used, so that
the data is discarded.
4 102911. A scanning period of the Onephone terminal is determined to make
the Oncphone
terminal to be moved between service networks without having the user known,
and has to
6 simultaneously satisfy a method for minimizing power consumption of the
terminal.
7 [02921 Hereinafter, a method for scanning the terminal in the case of
coverage movement of
the Onephone terminal will be explained.
9 [0293) .At first, an active scanning duration of the Onephone terminal is
at least longer than the .
paging interval time of the AP (Access Point).
ii [02941 There is a case that the AP does not perform the paging and
responds only when the
12 terminal makes a request according to a narrowband service protocol,
which does not affect an
13 active scanning duration of the terminal and means that the AP has to
wait for the maximum
14 response time of the AP.
IS 10295] Also, when it is determined that the Onephone terminal moved from
the narrowband
16 network to the broadband network, the Movement is determined according to
the RSS1 and
17 signal/data frame error rate. Moreover, when it is determined that the
Onephone terminal is
1g moved to the broadband network, the scanning period is shortened, and in
the case that the
19 Onephone terminal is Out of the service area, the scanning period is
widened in order to reduce
20 the power consumption of the terminal. That is, the idle time period
lengths.
2] 10296] On the contrary, in the case that the Onephone terminal moves from
the broadband
72 network to the narrowband network, the Onephone terminal is scanned as
done in the broadband
70
CA 02457606 2009-05-04
since it is not possible to recognize the movement to the narrowband, and when
there is at least
2 one of AP scanning, it is determined that the Onephone terminal moves to
the narrowband by
3 changing the scanning period.
4 102971 On the other hand, in the case that the Onephone moved from the
broadband network
(external network) to the narrowband (AP), the Onephone managing server of the
external
6 network is informed of the internal network usage through the AP wired
data network in the state
7 that transfer to the AP internal network should be performed, or the
Onephone managing server
a is informed of the internal network usage through the external network
before the internal
9 network is used. .
to [0298] Also, when the Onephonc moves from the AP to the external
network, since the
Onephone recognizes that the Onephone is not sensed in the AP, it informs the
Onephone
12 managing server that the Onephone moved to the external network, or the
Onephone which
13 moved to the external network informs the external network Onephone
managing server of the
11 termiiial movement through the external network directly.
[0299] Hereinafter, a method for performing a data service in a narrowband
service network
16 using the Onephone terminal is explained.:
17 103001 At first, a method of registering an initial Onephone terminal
in the narrowband service
18 network will be explained.
19 [030IJ At first, the narrowband service AP is established as a
registrable mode.
[0302] Next, the Onephone terminal requires the user to input a
registration system ID
21 (identification) or information on a user's ID or a password.
71
CA 02457606 2009-05-04
[0303) When all kinds of information for registering the Onephone terminal is
inputted from
the user, the Onephone terminal transmits the inputted information to the AP,
and the AP
3 performs a nan:owband network registration process according to all the
kinds of information
4 transmitted from the Onephone terminal_
[0304] The AP stores information on the registration Onephone terminal and
establishes the
6 narrowband service AP.as a registration release mode.
7 10305] On the other band, a method for using a wired data network is
explained after the
8 Onephone terminal is registered in the parrowband network through the
process described above.
9 [03061 It is a service available method:in the case that the AP or
private exchange supporting
the Onephone terminal service has a circuit except for the PSTN interface, to
which data service
11 can be provided.
12 103071 Firstly, all Onephone terminals may have a temporary (dynamic) IP
(Internet Protocol
13 address) or a fixed (static) IP through an IP assignment process in
order to use the data service if
14 possible.
103081 In the process of obtaining that, an authentication for the Onephone
terminal can be
16 performed, wherein the method used to make the authentication uses a PPP
(point-to-point
17 protocol) so that the user's ID and password are exchanged
(authentication flow such as PAP,
18 CHAP), an authentication of the terminal or user is performed, a data
session is opened between
19 the Onephone and the wired data service network, and an "Account start"
for the data session
==)() can be performed.
21 [0309] On the contrary, even though there may be a case that a separate
authentication
22 protocol can be used after assigning the IP through DHCP (Dynamic Host
Configuration
72
CA 02457606 2009-05-04
Protocol), this case includes a case that encryption and authentication arc
performed together in
the Layer 3 level. The encryption used atEthis time may be 802.1x and so on.
3 103101 On the other hand, the user of the Onephone can be connected to a
wired data service
4 network by placing an independent hot key in the Onephone or using a menu
key and an item
key on the sub-menu in order to provide a data service.
6 [0311] The user of the Onephone can be connected to the wired contents
server (for example,
7 an application server) through the connected wired network and provide a
game and bell sound
8 through a contents server in this case. The public network makes the
Onephone user connected
9 to the contents server of the wired network.and provides a specialized
home networking service
0 of the user (for example, Home view, appliance control service, etc.)
ii [03121 On the other hand, while attached FIGS. 13 to 17 explain the case
of the HLR being
12 installed in each of the mobile network, and private wireless network,
only one HLR used to
13 register information on the subscriber and location of the complex
wireless terminal is
constructed, information on the private Wireless network and location of the
mobile network is
stored and registered together in one HLR, and the incoming call is
transferred to the
16 corresponding network according to information on the location of the
corresponding terminal
registered in the HLR when the voice and data call services are requested from
the complex
is wireless terminal. Such an embodiment makes it possible to provide the
voice and data services
19 to the corresponding terminal where the private wireless network and
mobile network are located
using a true Onephone, that is, a terminal. number.
21 [03131 In other words, when an incoming request signal is received from
the complex wireless
22 terminal, it. is possible to provide the voice and data services of the
private wireless network and
73
CA 02457606 2009-05-04
mobile network using one terminal number by obtaining information on a
location of the
2 corresponding terminal from the flIR (Home Location Register) and
transferring the
3 corresponding incoming call to a network corresponding to location
information of the terminal.
4 Here, the HLR may be installed in the private wireless network or in the
mobile network.
=
=
6 103141 - There is provided a complex Wireless service apparatus using a
wired and wireless
7 communication system and a method thereof in accordance with the present
invention, wherein
8 when a call is not reachable in one network in the complex wireless
terminal, the call can be
9 received through another network, and the service user can make a
communication without any
disconnection by providing a hand off between networks for the complex
wireless terminal when
the user moves from one network to another network during making a call.
12 [03151 Also, on transmitting an outgoing phone number and an extension
number from a
13 mobile switching center to a wired and wireless complex gateway, the
numbers are easily
14 transmitted using an outgoing phone display function, and a usage
convenience of the complex
wireless terminal can be enhanced by providing a handoff for plural band and
plural mode of the
16 complex wireless terminal and then guaranteeing mobility.
17 [03161 Also, the user can save a communication charge by automatically
providing a service
:S for the complex wireless terminal through an extension wireless network,
and a demand for the
19 complex wireless terminal can be generated by providing a handoff
between networks for the
complex wireless terminal and overcoming a defect of the complex wireless
terminal.
