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.

Abstract: When a capsule is manufactured, a unique number such as a serial number is stored in non-volatile memory in the capsule. If the capsule is used with an external apparatus, the unique number is sent from the capsule to the external apparatus. The external apparatus relates each unique number with a capsule ID comprising a small number of bits in a management table formed in non-volatile memory and sends the capsule ID to the capsule, and the capsule ID with the small number of bits is set as an identifier in the capsule. In this manner, it is made unnecessary to provide a switch in the capsule for setting the identifier and it becomes possible to reduce and send the quantity of information sent as the identifier.
