Since it is not possible to maintain and manage the TTP cookie information, communication while maintaining the session of the HTTP protocol cannot be performed. In addition, there has been no other way but to obtain information for identifying the terminal of the mobile phone according to the specifications of the service provider.

[0003]

In the conventional environment described above, general-purpose HTTP cookie information cannot be used for session management, and a large number of W
An EB site cannot maintain a session and cannot build a WEB application.

[0004] The present invention acts as a proxy for HTTP cookie retention and management, and the WEB on a mobile phone that cannot perform cookie retention and management.
This is to enable a browser to use a WEB application that maintains a session using an HTTP cookie.

[0005]

According to the proxy server of the present invention, if an HTTP request transmitted by a user has cookie information corresponding to the request URL and terminal information in a cookie storage unit, the cookie information is stored in an HTTP header. Add and send. If there is cookie information in response to the response from the server, the cookie information is stored in the cookie storage unit.

FIG. 1 shows an example of the basic configuration of the present invention, in which a user's portable telephone terminal 1 and a WEB server 6 are connected.
Are connected via a telephone switching network (or packet switching network) 2, an IP telephone switching network gateway 3, a cookie proxy server 4 according to the present invention, and the Internet 5. The IP telephone switching network gateway 3 relays an IP network and a telephone switching network (or a packet switching network).
In addition, the information (telephone number etc.) specifying the user's mobile phone terminal 1 is obtained from the telephone exchange network (or packet exchange network) 2 and the information can be disclosed in response to an inquiry of the cookie proxy server 4 according to the present invention. .
Alternatively, when the function of the cookie proxy server is added to the IP telephone exchange network gateway 3 as in claim 2, the function of the cookie proxy server can also acquire the above information.

[0007] When a user request is sent from the user's mobile telephone terminal 1 via the telephone switching network (or packet switching network) 2 and the IP telephone switching network gateway 3, the cookie proxy server 4 inquires the gateway 3. And obtain information for identifying the terminal. Looking at the information specifying the terminal obtained above and the request URL of the user request, if the cookie information is held, the cookie information is added to the packet, and the W
Send to EB server 6. If the cookie information is not held, the cookie information is transmitted to the WEB server 6 via the Internet 5 as it is.

If the response packet returned from the web server 6 contains cookie information, the cookie information is stored in the cookie storage unit. The response packet is transmitted to the user mobile telephone terminal 1 via the IP telephone switching network gateway 3 and the telephone switching network (or packet switching network) 2.

[0009]

FIG. 2 is a block diagram showing a cookie proxy server according to the present invention. The cookie proxy server of the present invention includes a user request receiving unit 21 that receives a request from a user, an HTTP cookie addition determining unit 22 that determines whether to add cookie information to the received user request, and that actually performs addition. A user mobile phone terminal information acquisition unit 23 for specifying a user mobile phone terminal from which a user request packet is transmitted;
A cookie storage unit 24 that stores cookie information using the RL and user mobile phone terminal information as search condition keywords;
A session temporary storage unit 25 for temporarily storing a protocol session with a mobile phone terminal during exchange with the WEB server, a user request transmission unit 26 for transmitting a user request, and a response packet returned from the WEB server A cookie information storage determining unit 28 that acquires cookie information in the response packet and stores the cookie information in the cookie storage unit, and a response packet transmitting unit 29 that transmits the response packet to the user mobile phone terminal. It is configured.

[0010] The user request received by the user request receiving unit 21 is an HTTP cookie addition determining unit 22.
Passed to. The HTTP cookie addition determining unit 22 looks at the content of the user request and makes an inquiry to the user mobile phone terminal information obtaining unit 23 to obtain user mobile phone terminal information (telephone number and the like). Then, the communication session and the user mobile phone terminal information are stored in the session temporary storage unit 25, and then the cookie storage unit 24 is referred to using the user mobile phone terminal information and the URL present in the user request as search conditions. Here, if the cookie information exists in the cookie storage unit 24, the cookie information is added to the HTTP header of the user request. Then, the user request is passed to the user request transmitting unit 26, and the user request transmitting unit 26 transmits the user request to a target access destination.

[0011] The response packet receiving unit 27 receives the response packet returned from the server and passes it to the cookie information storage determining unit 28. Cookie information storage determination unit 28
Checks the contents of the response packet to see if the cookie information exists. If there is the cookie information, the communication session information, the cookie information, and the URL are obtained from the response packet, the user mobile phone terminal information is obtained from the communication session information by referring to the session temporary storage unit 25, and the user mobile phone terminal information is obtained. Cookie information is stored in the cookie storage unit 24 using the URL as a search condition keyword. Then, the response packet is passed to the response packet transmitting unit 29, and the response packet transmitting unit 29
Sends a response packet to the user's mobile phone terminal.

From now on, the description of the operation will be supplemented with reference to FIGS. The user mobile phone terminal information acquisition unit 23 uses the IP
It inquires of the telephone exchange network gateway 3 about user mobile phone terminal information. Alternatively, if user mobile phone terminal information exists during the user request, the information is extracted. When adding the function of the cookie proxy server 4 according to the present invention to the IP telephone exchange network gateway 3,
It inquires of an exchange existing on the telephone switching network (or packet switching network) 2 or receives a signal on the telephone switching network (or packet switching network) to acquire user portable telephone terminal information. This user mobile phone terminal information acquisition means may be any method.

If the HTTP cookie addition determining unit 22 refers to the cookie storage unit 24 and there is no cookie information, the user request packet is passed to the user request transmitting unit 26 without editing.

Before the cookie information storage determining unit 28 passes the response packet to the response packet transmitting unit 29,
Cookie information may be deleted.

[0015]

When the cookie proxy server of the present invention is installed in an Internet service provider using a mobile phone browser, communication using cookie information can be performed even if the cookie information cannot be processed by the browser on the mobile phone. . Therefore, the user can be specified from the first access on the server side, but the privacy of the user can be protected because the terminal information of the mobile phone is not transmitted. Further, since standard cookie information is used in the HTTP protocol, a Web application can be created without having to consider new specifications on the server side.

On the server side, a similar application can be created simply by placing the server on the Internet. In particular, an Internet service provider (usually a mobile phone company) having a connection point with a telephone switching network or a packet switching network for mobile phones. There is no need to sign a contract, which can greatly contribute to the expansion of information services on mobile phones.
