Abstract

PROBLEM TO BE SOLVED: To comfortably utilize an Internet service on the Internet by attaining connection for a PHS(R) call without using the switch of a line exchange node. SOLUTION: When a PHS (R) subscriber (a) desires to receive the Internet service, the PHS (R) subscriber (a) originates a line exchange call and connects it to a PHS (R) base station (b). When the dial number of this PHS (R) subscriber (a) is a telephone number for Internet connection, the PHS (R) base station (b) does not connect the originated call of the PHS (R) subscriber (a) to the line exchange node but connects it to a gateway device (d). Then, this gateway device (d) authenticates the subscriber by accessing a service control node (f) to be utilized for a line exchange service. Further, the gateway device (d) connects the originated call of the PHS (R) subscriber (a) to an Internet server (e) by performing signal conversion and media conversion from a line exchange protocol to an Internet protocol.

[0001]

The present invention relates to an Internet connection system and method, and more particularly, to an Internet connection system and method for connecting to the Internet using a PHS and using various services.

[0002]

2. Description of the Related Art In recent years, a PHS (Personal Handyphone System) in which an analog cordless telephone is digitized has become widespread. When a PHS service is used by using the PHS, it is known that the communication of the PHS call uses a circuit switching network. In addition, it is known that communication of data or call information possessed by the PHS base station uses a packet network (refer to the Telecommunication Association of Japan and the easy intelligent networks p94-p99, etc.).

[0003]

However, in the above-mentioned PHS service system, when a plurality of PHS subscribers perform simultaneous transmission and the like, the traffic increases, and when the amount of information flowing in a certain time increases, the information delay occurs. And the likelihood of loss increases. Further, when connecting to the Internet or the like, there is a case where the processing capability of the switch of the circuit switching node is squeezed and it becomes difficult to communicate a PHS call.

[0004] In view of the above, the present invention aims at communicating PHS calls without using a switch of a circuit switching node when a PHS subscriber connects to the Internet, and provides comfortable communication via the Internet network. It is an object of the present invention to provide an Internet connection system and method capable of performing the above.

The gateway device d accesses the service control node f, and the service control node f executes a position registration of the PHS subscriber a and a request to acquire authentication data via the PHS base station interface f1 (step 3). ). Then, the service control node f updates the location information of the PHS subscriber a held in the location information section f2, acquires the authentication data held in the authentication data section f3 as a response, and sends the authentication data to the gateway device d. I will send it back. The gateway device d performs an authentication operation based on the received authentication data (Step 4). Further, the gateway device d issues an authentication request to the PHS subscriber a (step 5), and receives an authentication response including the result of the authentication calculation performed by the PHS subscriber a (step 6). Then, the gateway device d confirms the result of both authentication operations. If the authentication is successful, the gateway device d performs signal conversion from the circuit switching protocol to the Internet protocol and media conversion, and performs communication between the PHS subscriber a and the Internet server e. To establish a link (step 7) and complete the connection to the Internet.

Next, a description will be given of a case where the PHS subscriber a communicating with the Internet is moving when the connection to the Internet is completed.

The PHS subscriber a makes a call to the PHS base station b 'including data which can specify that the mobile station is moving during Internet communication (step 8). The PHS base station b 'makes a server access request to the corresponding gateway device d' (step 9). Further, the gateway device d ′ is provided to the service control node f by
It requests the acquisition of authentication data (step 10), receives the response, and performs an authentication operation from the authentication data of the PHS subscriber a (step 11). Next, the gateway device d 'makes an authentication request for the PHS subscriber a (step 12). The gateway device d 'is a PHS subscriber a
(Step 13), and confirms the authentication calculation result. The gateway device d 'performs the authentication, and if the authentication is good, executes a location information acquisition request to the service control node f (step 14), and transmits the location information of the PHS subscriber from the service control node f. A response including the response is received (step 15). Further, the gateway device d that is establishing a link with the Internet server e is specified, and a connection switching request is made (step 16). Thus, the switching between the gateway devices d and d 'can be performed without disconnecting the communication due to the superposition of the Internet connection. Further, the completion of the switching between the gateway devices d and d 'is notified by a response (step 1).

It is connected to the Internet server e via the gateway device d '. Therefore, it is possible to realize an Internet connection system that can continuously use the circuit switching network N and the Internet network M regardless of the movement of the PHS subscriber during communication.

In the above-described embodiment, the base stations b and b 'for controlling the Internet connection are replaced by the base stations b and b'.
When downloading the data of b ', base stations b and b'
When the download is instructed by a circuit-switched call from the circuit-switched nodes c and c ', the gateway device autonomously uses the gateway devices d and d' and the Internet server e.
May be connected to the Internet, and data may be downloaded via the Internet. Also, when the base stations b and b 'that control the Internet connection upload the stored call information from the subscriber (terminal) a, the base stations b and b' store the call information to some extent. When it is determined that the gateway device d,
It is also possible to use d ′ and connect the Internet to the Internet server e to upload data via the Internet. Furthermore, although the PHS has been described as an example of a terminal, any terminal that can use the Internet service is not limited thereto, and an appropriate terminal can be used.
