TECHNICAL FIELD
The present invention relates in general to soft
handoffs and in particular to methods and systems for
establishing soft handoffs between two CDMA base stations
(BSs) using a direct base station (BS) to BS link even
where the SDUs associated to the BS comprise part of
different configuration systems.

BACKGROUND
When a mobile station (MS), in a cellular
communication system, crosses from one cell to another
adjacent cell a process designated as handoff is initiated.
Handoff is the process by which a new air interface
channel between a mobile station and a base station is
established.
There are several types of handoff in the wireless
communication industry. A "hard handoff" is a handoff
which requires a mobile station to tune its radio equipment
or to reestablish synchronization. A "soft handoff" is a
handoff that does not require the mobile station to tune
its radio equipment or to reestablish synchronization and
that uses the same frame selection function for (and voice
trans-coding function, if this is a voice call) in the
network for both the old and new air interface channels.
Other types of handoffs, such as a semi soft handoff, are
not pertinent to an understanding of the present invention.
At the present time, only code division multiple access
(CDMA) wireless communication systems are capable of
accomplishing soft handoffs.
In a CDMA wireless communication system, using
cellular transmission technology, the process of
establishing a soft handoff from the time an MS sees a new
pilot signal, received from a nearby base transceiver
station (BTS) defining another cell, to the time an MS
3
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
sends a handoff completion message can be segregated into
at least three phases.
Phase 1 may be defined as occurring from the time the
MS sees a new pilot to the time that the pilot strength
exceeds a predetermined threshold and may be referred to as
the detection phase. Phase 2 may be defined as occurring
between the time an MS sends a pilot strength measurement
(PSM) message until it receives a handoff direction message
and may be referred to as the establishing phase (when
successful). Phase 3 may be defined as the time from when
an MS receives a handoff direction message to the time the
MS sends a handoff completion message and may be referred
to as the completion phase.
As is well-known in the art, many standards are used
by the communication industry to define functional
standards by which communication equipment will operate so
that equipment from various manufacturers may compatibly
inter-operate. One such standard is IS-95 Revision A
entitled "Mobile Station - Base Station Compatibility
Standard for Dual-Mode Wideband Spread Spectrum Cellular
Systems; May, 1995". Another standard is IS-634 Rev A
ballot version dated April 20, 1997 entitled "MSC BS
Interface for Public Wireless Communication" that among
other items defines radio access to switch or intr-system
interfaces. A further standard mentioned in this document
is IS-41-C entitled "Cellular Radiotelecommunications
4
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
Intersystem Operations; 1996". Each of these standards are
incorporated herein by reference.
The IS-634 standard has defined and standardized
communications between a mobile switching center (MSC) and
a BS by industry agreement such that different
manufacturers equipment could be combined into a composite
cellular system by a user. However this standard has not
previously attempted to standardize any signaling messages
between base stations. Thus, signaling messages bound from
a source base station to a target base station, must be
first relayed to an MSC in a standardized manner and
protocol before being received by the target base station.
To support soft handoff of an MS moving from one cell
to another, adjacent cells must operate at the same
frequency. Once an MS detects a new pilot, the MS may
experience same frequency interference from adjacent cells.
In accordance with the standards of IS-95, 12 consecutive
bad frames detected by an MS may cause the MS to drop a
call. The total network processing time that may cause a
call to be dropped is primarily a function of the phase 2
time period. At this time the received signal has already
degraded enough that a handoff has been requested. This
typically means that the MS is still moving away from its
signal source. Thus the degradation of received signal
quality, before handoff completion, may result in the
occurrence of 12 consecutive bad frames as detected by the
MS.
5
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
One prior art system used 12 steps and including the
transmission of 12 messages for an intra-system inter-BS
handoff during phase 2. The series of setup and request
messages went from the MS, to the serving BTS, to the
selection/distribution unit (SDU), the serving base station
controller (BSC), the mobile switching center (MSC), the
target BSC, and the target BTS. The response messages came
from the target BTS to the target BSC, the MSC, the serving
BSC, the SDU and finally the serving BTS.
For an inter-system handoff, at least 14 steps were
completed because of the extra MSC and even the STP
involved in both directions.
It takes time to successfully transmit a message and
to process the message after receipt. It will be apparent
that the time required to complete the referenced 14 steps
must occur prior to the length of time it takes the MS to
move to a position where the quality of the signal received
by the MS has degraded to a point whereby the MS detects 12
consecutive bad frames. This time problem is especially
severe when the MSC is involved in many administrative
tasks other than call processing.
Thus a system whereby the number of steps involved and
the number of messages transmitted could be reduced for the
establishment process of phase 2 would lessen the chances
of a call being dropped due to extensive time required to
complete this phase. The elimination of the MSC from the
message path, even where there was no reduction in number
6
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
of steps involved, due to a required addition of dedicated
processing entities, would also reduce the time required to
complete phase 2 in some circumstances.
It would further be desirable, if base stations,
whether identical or made by different manufacturers, could
communicate directly with one another to establish a soft
handoff of an MS across cellular boundaries of
communication cells managed by different base stations.
One attempt to solve the above problem was presented
in a patent application assigned to the assignee of the
present invention, filed April 7; 1998, entitled "METHODS
AND SYSTEMS FOR STANDARDIZING INTER BASE STATION
COMMUNICATIONS" and having a filing number designation of
09/056,370.
There are two architectures supported in the
referenced IS-634 standard. An Architecture A network
infrastructure is distinguished by the fact that the voice
coding and frame selection function of the SDU is always
located at the source base station. An Architecture B
network infrastructure is distinguished by the fact that
the voice coding and frame selection function of the SDU is
located remote from the source base station and thus
requires the use of an A4 communication interface as
defined in the standard. A typical location for the SDU in
an architecture B network is in the MSC although it may, if
7
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
so desired, be physically isolated from the rest of the
system.
The above referenced patent application does not
address a solution to the quicker establishment of soft
handoffs between base stations comprising part of different
architecture systems.

SUMMARY OF THE INVENTION
The present invention comprises providing a soft
handoff signaling channel or communication link directly
between source and target systems. This communication link
in combination with an enhanced signaling link from the
source SDU to the target BS, operate to permit the
transmission of both signaling and voice information from
the SDU, and removes the involvement of the MSC from the
soft handoff establishing phase process.

DETAILED DESCRIPTION
The referenced copending application is directed to
the idea of adding a communication link between base
stations to bypass or eliminate the requirement of signals
passing through the MSC. The concept as presented therein
is not readily implementable as applied to CDMA
architecture B type systems or to a SHO.between systems
having different architecture types.
In this application, separate signaling and traffic
links are utilized to allow inter-system soft handoff
operations to bypass the MSC whether the systems are both
architecture type B, or both type A or between different
architecture types.
This is accomplished by using 3 links, as will be
explained in greater detail later, A7 signaling, A3
signaling and A3 traffic. Each link may terminate
logically at different entities in different architecture
type systems. This flexibility of link termination
provides the inter-operability necessary in establishing
direct links between certain entities in different
architecture type systems and as required to remove the
involvement of the MSC from the soft handoff establishing
phase of the operation.
In FIGURE 1 a block designated as MSC is also labeled
10. MSC 10 is connected via a communication link 12 to a
cloud designated as 14 and also labeled STP. STP refers to
12
CA 02299456 2000-O1-25
*rB
WO 99/07174 PCT/US98/15048
a signal transfer point, gateway or other signal switching
network such as the public switched telephone network
(PSTN). The link 12 transfers data according to an IS-41
protocol as referenced in the previously mentioned industry
standard. Cloud 14 is further connected via a link 16 to
a further MSC block 18. Link 16 also conforms to the IS-41
protocol. A base station block 20 is connected via a
communication link 22 to MSC 18. The communication link 22
conforms to IS-634 standards. A further base station 24 is
connected via a communication link 26 to MSC 10. Link 26
also conforms to the IS-634 protocol. A circle 28
represents a mobile station (MS) that is moving from the
base station 24 towards base station 20. An airwave
communication link 30 represents communications between MS
28 and base station 24. A dash line 32 represents airwave
communications between MS 28 and base station 20. The
cellular system represented by blocks 10 and 24 may be
either an architecture A or architecture B type system as
defined in IS-634. As shown in the drawing, the same
applies to a second cellular system represented by blocks
18 and 20.
Figure 2 provides the basic components involved in a
soft handoff between two systems conforming to architecture
A. This is the model used in the referenced patent
application. An MSC block 40 communicates over a link 42,
through a cloud 44 and a further link 46 with a second MSC
48 in the same manner as shown in FIGURE 1. MSC 40 also
13
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/I5048
communicates with a BS 50 over a link 52 conforming to IS-
634 standards. A further BS 54 communicates with MSC 48
over a communication link 56 where 56 is IS-634 compliant.
Both BSs 50 and 54 actually comprise at least one BSC and
normally a plurality of BTSs. A communication link is
shown providing a direct connection between a voice and
signaling (V/S) portion of BS 50 and a similar portion of
BS 54. The V/S portion in most CDMA systems comprise an
SDU and associated soft handoff controller (SHC). A
interconnection function (ICF) block (not shown) may be
required in older system designs to transmit data over the
link 58 in a protocol that complies with an accepted
industry standard.
As shown in FIGURE 1, the mobile station 28 has been
communicating with base station 24. As MS 28 moves towards
the base station 20, the mobile station 28 receives pilot
signals from BS 20 of increasing amplitude. When the
signals exceeded a predefined value, the mobile station 28
informs base station 24 that it wants to be transferred to
the system represented by base station 20. The base
station 24 informs MSC 10 which transfers messages over
communication link 12 through STP 14 and eventually to BS
20. BS 20 allocates resources so that it may communicate
with mobile station 28. Messages are then sent back
through STP 14 to base station 24 to acknowledge that BS 20
is prepared to complete a connection with mobile station
28. The process of transferring these messages and the
14
CA 02299456 2000-O1-25
WO 99/07174 PCT/I3S98/15048
many steps involved, when using only MSC to MSC
communication, is set forth in detail in the referenced
patent application.
The referenced patent application is directed to the
idea of providing direct BS to BS signaling to establish
the soft handoff connection. As presented, the invention
suggested that one method of accomplishing this soft
handoff signaling link is to enhance an existing voice and
signaling communication channel designated in the standards
as A3. Such a system is illustrated in FIGURE 2.
FIGURE 3 shows the same concept applied to a handoff
between architecture B type systems. As shown, one system
comprises an MSC 70 and a BS 72. A second system comprises
an MSC 74 and a BS 76. IS-41 Links connect the two MSCs
together via an STP cloud 78. A direct link labeled as 80
provides signaling and voice communication between the
appropriate components of the two systems necessary to
establish a soft handoff. Non designated communication
links interconnect the MSC and its associated BS and these
links are IS-634 compliant. While the number of message
steps saved may be slightly less than occurs between two
architecture A systems, the time saved may still be
significant .
A further significant advantage will be apparent from
an examination of FIGURE 4 where a soft handoff is shown
occurring between two different architecture type systems.
An architecture B system is shown having the basic
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
components of an MSC 90 and a BS 92. An architecture A
system is shown having the basic components of an MSC 94
and a BS 96. IS-41 links connect the two MSCs together via
an STP cloud 98. A V/S to V/S direct link labeled as 100
provides signaling and voice communication between the
appropriate components of the two systems necessary to
establish a soft handoff. Non designated communication
links interconnect the MSC and its associated BS and these
links are IS-634 compliant.
By setting up a standardized protocol whereby each of
the links 58, 80 and 100 in the appropriate FIGURES 2, 3
and 4 conform to the same communication standard, any
architecture type system may establish a soft handoff with
another system without having to pass the establishing
messages to the STP cloud.
The inter-operability approach set forth in FIGURE 4
is expanded upon in FIGURES 5 and 6 and the manner in which
messages are exchanged between systems for four different
source and target combination possibilities is presented in
FIGURES 7 through 10.
In FIGURE 5, a network or switch mechanism labeled as
STP and given a designation of 110 is connected to each of
a plurality of MSC blocks 112, 114, 116 and 118 over IS-41
compliant communication links. MSCs 112 and 114 provide
the main switch function for two architecture A type
cellular systems. MSCs 116 and 118 provide the main switch
function for two architecture B type cellular systems.
16
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
Each of the MSCs is connected to base station equipment
over IS-634 compliant communication links. MSC 112
controls a BSC 120 which in turn controls a first plurality
of BTSs 122 and a second plurality of BTSs 124. Internal
to BSC block 120 there is shown an SDU block 126.
MSC 114 controls a BSC 128 which in turn controls a
plurality of BTSs 130. Internal to BSC block 128 there is
shown an SDU block 132. MSC 13.6 controls a BSC 134 which
in turn controls a plurality of BTSs 136. Internal to MSC
block 116 there is shown an SDU block 138. MSC 118
controls a BSC 140 which in turn controls a plurality of
BTSs 142. Internal to MSC block 118 there is shown an SDU
block 144.
Three asynchronous transfer mode (ATM) clouds 146, 148
and 150 provide direct V/S to V/S interconnection between
the four cellular systems. The connections are shown as
solid, dashed and dotted lines for different types of
communications. The bold solid lines designated A3T
represents A3 protocol voice or data (traffic) packets, the
dotted line designated as A3S represents A3 protocol
signaling data packets and the dash line designated as A7
represents a data packet protocol for passing resource
allocation signaling type messages.
Three different MS blocks are designated as 152, 154
and 156. MS 152 is shown as being handed off from a source
system using one of the BTSs 124 to a target system using
one of the BTSs 130. Similarly, MS 154 is shown as being
17
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
handed off from one of a set of source BTS 136 to one of
the set of target BTSs 130. Finally, MS 156 is illustrated
as being handed off from one of the source BTSs 136 to one
of the target BTSs 142.
The cellular systems using BSCs 120 and 134 are
further labeled SOURCE while the systems using BSCs 128 and
140 are further labeled TARGET in accordance with the above
paragraph. The A3 and A7 communication links as shown are
used to help illustrate the paths messages travel in
performing a soft handoff between a source system and a
target system in the practice of this invention.
When the source and target systems are both
architecture A type systems all communications take place
between the BSCs as shown in connection with ATM 146. The
A3 protocol signaling and voice messages are transferred
between the BSs in each of the two systems. The A7
resource allocation messages are transferred between the
soft handoff controllers internal the respective BSCs to
transfer a handoff request and the response acknowledgement
to that request between the appropriate BTS entities.
In FIGURE 6, a network or switch mechanism labeled as
STP and given a designation of 200 is connected to each of
a plurality of MSC blocks 202, 204, 206 and 208 over IS-41
compliant communication links. MSCs 202 and 204 provide
the main switch function for two architecture A type
cellular systems. MSCs 206 and 208 provide the main switch
function for two architecture B type cellular systems.
18

WO 99/07174 PCT/US98/15048
Each of the MSCs is connected to base station equipment
over IS-634 compliant communication links. MSC 202
controls a BSC 210 which in turn controls a first plurality
of BTSs 212 and a second plurality of BTSs 214. Internal
to BSC block 210 there is shown an SDU block 216.
MSC 204 controls a BSC 218 which in turn controls a
plurality of BTSs 220. Internal to BSC block 218 there is
shown an SDU block 222. MSC 206 controls a BSC 224 which
in turn controls a plurality of BTSs 226. Internal to MSC
block 206 there is shown an SDU block 228. MSC 208
controls a BSC 230 which in turn controls a plurality of
BTSs 232. Internal to MSC block 208 there is shown an SDU
block 234.
Three asynchronous transfer mode (ATM? clouds 236, 238
and 240 provide direct V/S to V/S interconnection between
the four cellular systems. The connections are shown as
solid, dashed and dotted lines for different types of
communications. The bold solid lines designated A3T
represents A3 protocol voice (traffic) data packets, the
dotted line designated as A3S represents A3 protocol
signaling data packets and the dash line designated as A7
represents a data packet protocol for passing resource
allocation signaling type messages.
Three different MS blocks are designated as 242, 244
and 246. MS 242 is shown as being handed off from a source
system using a BTS such as 220 to a target system using one
of the BTSs such as 214. Similarly, MS 244 is shown as
19
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
being handed off from one of a set of source BTSs 220 to
one of the set of target BTSs 226. Finally, MS 246 is
illustrated as being handed off from one of the source BTSs
232 to one of the target BTSs 226.
The cellular systems using BSCs 218 and 230 are
further labeled SOURCE while the systems using BSCs 210 and
224 are further labeled TARGET in accordance with the above
paragraph. The A3 and A7 communication links as shown are
used to help illustrate the paths messages travel in
performing a soft handoff between a source system and a
target system in the practice of this invention.
When the source and target systems are both
architecture A type systems, all communications take place
between the BSCs as shown in connection with ATM 236 in the
same manner as discussed in connection with FIGURE 5. The
same holds true when the source and target systems are both
architecture B type systems. The differences occur when
the source and target systems are of different types. This
will be further explained in connection with the following
figures.
In FIGURE 7 an MS is labeled 300 and is shown sending
a pilot strength measurement signal to a BS block 302 which
represents a combination of BTS/SDU/SHC/ICF entities since
the communication link interconnections of these entities
are proprietary to each manufacturer. The block 302 and an
MSC1 block 304 represent a source system. An MSC2 block
306 in combination with a BS block 308 represents a target
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
system. As above the block 308 represents a combination of
BTS/SDU/SHC/ICF entities. As mentioned previously, the
messages passed illustrate the time sequence of messages,
labeled from "a" to "1", when a soft handoff is being
established between two type A systems. This would be
representative of a soft handoff between the two left hand
systems of either FIGURES 5 or 6. When the source BS
determines that one or more cells at a target BS are needed
to support an already established call, it sends an A7
Handoff Request to the target BS as shown in line "b". The
target BS initiates an A3S connection by sending a Connect
message in return. (Although only one connect message is
shown, multiple connect messages may occur if the request
includes multiple cells.) Acknowledgments soon follow both
the HO request and connect messages. Forward frames are
commenced from the source to the target BS as shown in line
"f" as soon as synchronization is established. A message
is then sent to the target BS to begin forwarding traffic
frames to the MS as set forth in lines "g" and "h" . An
acknowledgement message is sent in line "j". After the
extended HO direction message is sent, the source MSC is
informed that the HO has been performed. As set forth
above, the MSC is bypassed from the establishment phase and
is merely informed that the HO is complete after the fact.
The messages used in the establishment phase of a soft
handoff between B architecture type systems in accordance
with this invention are presented in FIGURE 8. As
21
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
mentioned previously, the SDU in B architecture type
systems is not located in the base station. It may be
isolated by itself but is often found in proximity to an
MSC as shown in both FIGURES 5 and 6. A MS labeled as 350
may represent either MS 156 in FIGURE 5 or MS 246 in FIGURE
6. A BSC block 352, an SDU block 354 and an MSC1 block
356 represent a source system through which the MS 350 has
been communicating. In FIGURE 5 this would be the system
having MSC 116 while in FIGURE 6 it would be the system
having MSC 208. A MSC2 block 358, a BSC block 360 and a
BTS block 362 represent a target system such as shown and
labeled in FIGURES 5 and 6. As shown, the pilot strength
measurement signal is sent to the SDU 354 via an A3
communication link. As will be apparent to those skilled
in the art, the A3 communication link is distinct from the
previously 'discussed A3S and A3T communication links
although the protocol used is the same. A HO Request, as
shown on line "c", is sent on an A4 communication link to
the BSC represented by 352. This request is then
forwarded, as shown on line "d", over the A7 communication
link to BSC 360 and is forwarded over a proprietary link to
the BTS 362 representing an appropriate target BTS. A
connect signal is returned to the source SDU 354 over an
A3S communication link as shown on line "e". The remaining
signals utilized in establishing SHO in a type B
architecture system are shown and a comparison with either
FIGURE 5 or 6 will disclose the signal paths used to
22
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
provide the communication link. As before, the MSC is not
involved until the handoff is completed and a HO performed
message is sent from the BSC to the MSC as shown in line
"o" over communication link A7. The signaling messages are
substantially identical in both FIGURES 7 and 8 although
some need to be forwarded in accordance with established
protocols over standardized communication Links, such as A4
and A3.
In FIGURE 9, a signal transfer methodology is shown
for establishing a SHO between a source type B architecture
system and a target type B architecture system. A block
400 represents an MS such as 154 in FIGURE 5. A BSC block
402, an SDU block 404 and an MSC1 block 406 represents
components of the source system in FIGURE 5 having MSC 116.
A target MSC2 block 408 and a BSC block 410 are
representative of the system shown having MSC 114. As in
FIGURE 7, the block 410 includes at least the functional
entities ICF, SHC and BTS used to respond to the
intersystem messages used in this invention. In a manner
identical to FIGURE 8, the BSC 402 forwards a HO request
message subsequent to the occurrence of an appropriate
pilot strength measurement message of line "a" and a
resulting HO request message of line "b". This HO request
message is received over communication link A7 from a BSC
such as 134 in FIGURE 5. A connect message, as shown on
line "d", is returned over an A3S communication link to the
SDU such as 138. As shown, acknowledgment message of lines
23
CA 02299456 2000-O1-25
WO 99/07174 PCT/US98/15048
"e" and "f" are sent over communication links A3S and A7
respectively to the entities shown. The remaining messages
and communication links used are self evident in view of
the material already discussed.
The messages provided in FIGURE 10 illustrate the
entities involved in establishing a SHO between a source
architecture A type system and a target architecture B type
system such as may occur in connection with MS 244 in
FIGURE 6. A block 450 represents an MS while a BS block
452 and a MSC1 block 454 represent a source system through
which the MS has been communicating. The BS block 452
includes, as before, at least entities such as a BTS, a
SDU, a SHC and an ICF. A target system is represented by
MSC2 block 456, a BSC block 458 and a BTS block 460. The
HO request message is sent over the A7 communication link
to BSC 458 which is inherently programed to forward same
over a communication link, proprietary to type B
architecture systems, to a BTS as represented by block 460
and such as one of those designated as 226 in FIGURE 6. A
connect signal is returned over the A3S communication link
and then acknowledgments follow as described previously,
The remaining messages are transmitted and, when the SHO
operation is completed, a message is sent to the MSC 454
and designated as 204 in FIGURE 6 that the HO has been
performed. Thus the MSC again is not involved in the
establishment phase until it is completed and thus does not

act to impede the time required to complete the SHO
° operation.
The present invention thus establishes a methodology
that not only bypasses the MSC when attempting a SHO
operation between type A architecture systems as shown in
the referenced patent application, but allows the MSC
bypassing when attempting a SHO between different type
systems. A standardized set of signals is set forth herein
whereby all CDMA systems can communicate for the purpose of
, establishing a SHO without involving the MSC.
For the messages involved in the establishing phase as
well as in the release phase, Appendix A. provides an
example set of message-layout and information elements.
Although the invention has been described with
reference to specific embodiments, these descriptions are
not meant to be construed in a limiting sense. It is
therefore, contemplated that the claims will cover all
modifications or embodiments that fall within the true
scope of the invention.
