## Abstract

A Web access providing system that allows a user to access a Web page as if he or she is making a telephone call. When a user terminal B sends out a service request S1 and an originating connection request S12, a connection notification S4 is sent to a user terminal A through local Mobile multimedia switching system (L-MMS 1) and a gateway mobile multimedia switching system (G-MMS 2). When receiving the connection notification 4, the user terminal A performs authentication. The authentication verifies whether the telephone number of the user terminal B is contained in a telephone directory of the user terminal A. After the authentication, the user terminal A outputs a connection communication response S5 to the G-MMS 2. The connection communication response S5 contains the URL of a Web page associated with the user terminal A. The L-MMS 1 receives the URL and outputs a connection request S7. Thus, the user terminal B can access and browse the Web page implemented by a Web server 3.

## Claims

### Claim 1

A web access providing system via a switching system comprising:
connection request sending means for sending a request to connect a Web page associated with a called subscriber terminal by a calling subscriber terminal using at least one call provided in one communication channel based on multiple access technology;
authentication means for performing authentication of a subscriber number of said calling subscriber terminal in response to said call;
Uniform Resource Locator (URL) sending means for sending a Uniform Resource Locator (URL) to connect the call to the Web page associated with said called subscriber number stored in said called subscriber terminal depending on a result of said authentication by said authentication means; and
switching means provided in the switching system for receiving said Uniform Resource Locator (URL) and outputting a connection request to connect the call to the Web page,
wherein access to the Web page to which the URL is assigned beforehand by the user of the called subscriber terminal is granted only if an access code, which determines whether the call is requesting a voice conversation or access to a Web page, is added to the telephone number of the called subscriber terminal.

### Claim 2 (depends on 1)

The web access providing system according to claim 1, wherein said authentication is performed in said called subscriber terminal.

### Claim 3

A Web access providing system via a switching system comprising:
connection request sending means for sending a request to connect a Web page associated with a called subscriber terminal by a calling subscriber terminal using at least one call provided in one communication channel based on multiple access technology;
authentication means for performing authentication of a subscriber number of said calling subscriber terminal in response to said call;
Uniform Resource Locator (URL) sending means for sending a Uniform Resource Locator (URL) to connect the call to the Web page associated with said called subscriber number stored in said called subscriber terminal depending on a result of said authentication by said authentication means; and
switching means provided in the switching system for receiving said Uniform Resource Locator (URL) and outputting a connection request to connect the call to the Web page,
wherein the authentication by said authentication means verifies that the subscriber number of said calling subscriber terminal is contained in a subscriber number list associated with said called subscriber terminal and access to the Web page to which the URL is assigned beforehand by the user of the called subscriber terminal is granted only if an access code, which determines whether the call is requesting a voice conversation or access to a Web page, is added to the telephone number of the called subscriber terminal.

### Claim 4 (depends on 3)

The Web access providing system according to claim 3, wherein said subscriber number list is a telephone directory stored in said called subscriber terminal.

### Claim 5 (depends on 3)

The Web access providing system according to claim 3, wherein said authentication is performed in said called subscriber terminal.
