The telephone set is provided with a function as a service setting change means requesting the start and stop of service in a network side facility 1 at every subscriber information, a function as a switching detection means detecting switching of the telephone number used for communication with a telephone network and a base band processor 203 having a function as a control means requesting the start of service in the network side facility 1 from the service setting change means on the telephone number which is not used for communication and requesting the stop of service in the network side facility 1 from the service setting change means on the telephone number used for communication when switching is detected.

Description

technical field [0001] The present invention relates to a wireless communication terminal, specifically a wireless communication terminal such as a mobile phone equipped with a plurality of subscriber information such as a telephone number. Background technique [0002] Conventional mobile phones generally electronically hold a unique terminal number (telephone number or serial number, etc.) inside the terminal. This terminal number is used for authentication or payment when accessing the wireless telephone network. Moreover, in Europe, GSM (Global System for Mobile Communications), which is mainly used in mobile phones, and IMT-2000 (International Mobile Telecommunication 2000), which is called a new generation of mobile phones, generally continue to be adopted in mobile phones. Install IC cards called SIM (Subscriber Identity Module) and UIM (User Identity Module), and use the subscriber information (subscriber-related information such as telephone number and payment info...

Problems solved by technology

[0013] However, even if these countermeasures are taken, when the IC card is replaced by the user operation, or when the service area is moved, the previously used IC card cannot be used, and in the case of automatic switching to a new IC card, etc., it must be dealt with every time. There is a problem that it is necessary to perform complicated operations such as changing the telephone number of each IC card, setting the on-duty telephone, or starting and ending forwarding operations by the user himself.
