SYSTEM AND METHOD FOR PRIVATE SWITCHED BASED
COMMUNICATION TO A NETWORK SITE DURING NETWORK SITE
COMMUNICATION THROUGH A COMMUNICATION NETWORK
Back>:round Of The Invention
This invention generally relates to telecommunication systems and methods, and
more particularly, to systems and methods that communicate via a computer
network
such as the Internet.
As the number of users on large computer networks such as the Internet
continues to grow, electronic commerce is becoming increasingly important to
the
to business world. At present, numerous businesses advertise, perform
electronic
transactions and offer electronic payment methods on the Internet. This number
is
increasing rapidly because the Internet allows these businesses to operate
internationally
and have direct access to a extensive group of consumers. However, electronic
transactions and electronic payment methods require that secure information
such as
account numbers, personal identification codes, and credit card information be
sent over
the Internet where the information can be intercepted by unwanted entities.
Computer networks such as the Internet are unsecure networks because they
consist of a multitude of computers which are not controlled in any unified
wav The
networking technology employed by the Internet is very smart. Every time, a
new
?o computer is connected to the Internet, the Internet adopts that connection
as its ~w n and
begins to route Internet traffic over that connection and through that new
computer
Additionally, the Internet tragic follows multiple paths through multiple
computers to
assure proper reception at a destination site. As more computers are connected
to the
Internet, the network grows exponentially.
z, Unfortunately, every computer connected to the Internet can potentially
intercept
and read the Internet traffic that is routed through that computer. Thus, any
secure
CA 02298177 2000-02-07
Miller 1-7
information that is sent over the Internet may be potentially intercepted by a
large
number of computers connected to the Internet. Encryption has been used to
help
overcome this problem, however, encryption only makes it harder to access
information
and it does not prevent illegal access. Additionally there is no universal
encryption
standard and there are numerous legal and political hurdles which prevent
encryption
from being widely accepted as a secure way of doing business over a worldwide
Internet.
At present, many consumers are unwilling to transmit sensitive information
over
the Internet because of the fear that their credit card data is moving across
a hop by hop
shared public network enabling others the opportunity to capture the data from
within
to the network or backend servers holding the vital data. Additionally, the
available
encryption programs are difficult to operate and the laws governing these
programs
make them unattractive. Thus, in order to allow electronic commerce to grow,
there is a
need to implement a secure connection which will allow consumers to transmit
and
receive sensitive information with Internet enabled businesses.
Additionally, there is a need to allow consumers to communicate with Internet
enabled businesses in a two way voice method while still connect to the
Internet .-~t
present, Internet telephones are available which allow telephonic
communication via the
Internet. However, these Internet telephones have poor sound quality because
their
performance is limited by the performance of the Internet connection. Thus,
there ns an
2u additional need to allow consumers to communicate with businesses in a two
wav v nice
method that will maintain connection to the Internet.
Summary Of The Invention
The above problems are solved, and a number of technical advances are a~hrev
ed
in the art, by implementation of a ,vstem and method that allows a worldwide
Internet
?s connection to be combined with ~~ne or more point to point telephonic
connection:

following examples are illustrative of the operation of the communication
system 100 in
a electronic commerce application and two way voice or tone communication. For
exemplary purposes, computer device l05 is described as a personal computer
(PC), the
computer interface circuit 150 is a standard computer modem, the telephonic
switch l 10
is a standard telephonic switch such as the SESS digital switch from Lucent
Technologies, Inc., the communication network server 170 is an ISP, the
network 180 is
the worldwide Internet, the network server 120 is a computer system connected
to the
Internet, the network site 125 is a web page, the network site telephonic
interface 175 is
a standard modem and the connection 145 is a standard telephonic network.
to As seen in Fig. 3, in step 185, the computer device 105 sends a signal to
the
telephonic switch 110 that instructs the telephonic switch 1 10 to establish a
connection
with the communication network server 170. In step 190, the telephonic switch
I 10
sends a connection signal to the communication network server 170 to establish
a
connection with the network l 80 The communication network server 170, in step
I ~~~.
establishes a connection with the network I 80. In step 200, the communication
nem ork
server 170 responds by sending a reply signal that the connection with the
network I 30
is established. In step 205, the telephonic switch 110 informs the computer
device 105
that a connection to the network 180 exists.
In step 210, the computer device 105 communicates with the network 180 and
2o finds the network site 125. In step ? I 5, the computer device 105
communicates w ith the
network site 125. In step 220, the network site 125 sends a query signal to
the cumhumr
device 105 which queries whether to initiate a point to point signal
connection I-i~
between the network site 125 and the computer device 105 In step 225, the
cony,ut~r
device 105 responds to the query ai~;nal by requesting a point to point
connection woh
the network site 125 by sending a re,ponse signal to the network site 125. In
reap~~n.e

the computer device 105. The computer device 105, in step 235, then sends a
control
signal, via such interfaces as an application programming interface (API) or
by using
the telephony off hook flash followed by *signalling (e.g. *90) and the
destination
number. , to the telephonic switch 1 l0 requesting a point to point connection
with the
network site 125. In step 240, the telephonic switch 1 10 establishes a point
to point
connection with the network site I25. Then, in step 245, the computer device
105 and
network site 125 communicate point to point. The point to point connection is
a private
circuit or switched-based connection that is routed from one site to another
site across
either "private facilities" which does not appear on shared public facilities
or public
lu networks.
Illustrative of one form of the invention is a method for transmitting
communication signals from the telephonic switch 1 10, via the communication
newurk
115, to the network server 120 having the network site 125 for communication
with the
computer device 105 coupled with the telephonic switch 110. The steps of
connecting,
t5 the telephonic switch 1 10 to the network site 125 via the communication
network I I s,
and establishing communication across the point to point path (signaling path
14~ )
between the telephonic switch 1 10 and the network site 125 are performed
The step of establishing the point to point path 145 further includes the app:
~,t
creating, at the network site 125, the data signal containing the telephone
identitic,itmn
2e number for the network site I 25. and establishing a telephonic call from
the telephunm
switch 1 10 to the network site 1''S using the data signal. The step of
creating the tiara
signal further includes the steps of creating a query signal at the network
site I 2~.
transmitting the query signal tom the network site 125 to the computer device
I n~
creating a response signal at the computer device 105, and transmitting the
respun:~

the telephonic call further includes the steps of transmitting the data signal

the telephone identification number of the network site 125, from the computer
device
105 to the telephonic switch 1 10 and connecting the telephonic switch 1 10 to
the
network site 125 using the control signal.
While communicating point to point, the computer device 105 and network site
s 125 may exchange secure information such as financial account data, credit
card data.
personal data, or voice two way communication. In the example of two way
communication, the computer device 105 possess software, similar to commonly
available Internet telephone programs (some of which are embodiment in web
browses
produced by Netscape Communication, Inc. and Microsoft, Inc.), that allow the
