Abstract

In a communication system in which computer 20 transmits an HTTP request to WWW server 70 via broadband router apparatus 30 and the Internet 50, and WWW server 70 transmits an HTTP response to computer 20 according to the received HTTP request, broadband router apparatus 30 establishes an IP phone session and a TCP connection with HTTP proxy server 620 upon receiving the HTTP request from computer 20, and transmits the received HTTP request to WWW server 70 via HTTP proxy server 620.

Claims

1. A communication system comprising:

a first server;

a second server; and

a broadband router connected to a computer,

wherein;

the broadband router is configured to;

transmit a first request to the first server to establish an IP phone session with the first server, the first request transmitted to the first server in response to receiving an HTTP request from the computer and includes an IP phone number associated with the broadband router;

transmit an IP address of the broadband router to the first server during establishment of the IP phone session; and

in response to establishment of the IP phone session with the first server, initiate a TCP connection with the first server and transmit the received HTTP request to the first server after establishment of the TCP connection, and

the first server is configured to;

receive the HTTP request from the broadband router;

transmit the HTTP request received from the broadband router to the second server, the HTTP request for accessing a URL on the second server;

store the IP phone number and the IP address of the broadband router in association with each other when the IP phone session is established;

receive a request from the second server for authentication information for accessing the URL;

in response to receiving the request for authentication information, acquire the IP phone number corresponding to the broadband router;

retrieve authentication information corresponding to the IP phone number and the URL;

transmit the retrieved authentication information to the second server;

receive an HTTP response from the second server after transmitting the authentication information to the second server, the HTTP response including content associated with the URL; and

transmit the received HTTP response to the broadband router.

2. The communication system according to claim 1, wherein the first server is further configured to notify the broadband router that the authentication information is not stored in the first server if the first server is unable to retrieve the authentication information.

3. The communication system according to claim 1, wherein the first server is further configured to:

in response to receiving the HTTP response from the second server, register a communication start time in association with the IP phone number and the URL; and

in response to a termination of HTTP communication between the broadband router and the second server, register a communication end time in association with the IP phone number and the URL.

4. A communication method comprising:

receiving, by a broadband router, an HTTP request from a computer connected to the broadband router;

transmitting, by the broadband router, a first request to a first server to establish an IP phone session between the first server and the broadband router, the first request transmitted in response to receiving the HTTP request and includes an IP phone number associated with the broadband router;

transmitting, by the broadband router, an IP address of the broadband router to the first server during establishment of the IP phone session;

establishing, by the broadband router, a TCP connection with the first server in response to establishment of the IP phone session;

transmitting, by the broadband router, the received HTTP request to the first server after the TCP connection is established;

receiving, by the first server, the HTTP request from the broadband router;

transmitting, by the first server, the HTTP request received from the broadband router to a second server, the HTTP request for accessing a URL on the second server;

storing, by the first server, the IP phone number and the IP address of the broadband router in association with each other when the IP phone session is established;

receiving, by the first server, a request from the second server for authentication information for accessing the URL;

in response to receiving the request for authentication information, acquiring, by the first server, the IP phone number corresponding to the broadband router;

retrieving, by the first server, authentication information corresponding to the IP phone number and the URL;

transmitting, by the first server, the retrieved authentication information to the second server;

receiving, by the first server, an HTTP response from the second server after transmitting the authentication information to the second server, the HTTP response including content associated with the URL; and

transmitting, by the first server, the received HTTP response to the broadband router.

5. A communication method comprising:

receiving, by a first server, a first request from a broadband router to establish an IP phone session with the first server, the first request including an IP phone number associated with the broadband router;

receiving, by the first server, an IP address of the broadband router during establishing of the IP phone session;

storing, by the first server, the IP phone number and the IP address of the broadband router in association with each other when the IP phone session is established;

receiving, by the first server, an HTTP request from the broadband router for accessing a URL on a second server;

transmitting, by the first server, the received HTTP request to the second server;

receiving, by the first server, a request from the second server for authentication information for accessing the URL;

acquiring, by the first server, an IP phone number corresponding to the broadband router in response to receiving the request for authentication information;

retrieving, by the first server, authentication information corresponding to the IP phone number and the URL;

transmitting, by the first server, the retrieved authentication information to the second server;

receiving, by the first server, an HTTP response from the second server after transmitting the authentication information to the second server, the HTTP response including content associated with the URL; and

transmitting, by the first server, the received HTTP response to the broadband router,

wherein the first server includes a processor.

6. The communication method according to claim 5, further comprising:

registering, by the first server, a communication start time in association with the IP phone number and the URL, the registering in response to receiving the HTTP response from the second server.

7. The communication method according to claim 6, further comprising:

registering, by the first server, a communication end time in association with the IP phone number and the URL corresponding to the HTTP response, the registering in response to a termination of HTTP communication between the broadband router and the second server.

8. The communication method of claim 5,

wherein the first request is received by the first server prior to receiving the HTTP request.
