Abstract
A wireless communication apparatus stores a plurality of cellular phones in an extension, connects a plurality of cellular phones to a base station, and sets up the communication speed of a communication channel to a base station according to the communication speeds of a plurality of the cellular phones. The wireless communication apparatus maintains the communication speed of a communication channel when a total sum of the speed of the communication which one of the plurality of cellular phones starts and the speed of the communication previously performed is equal to or less than the communication speed of the communication channel. An IMT2000 network stores the wireless communication apparatus and the base station corresponding to a plurality of cellular phones in a location registration database and processes incoming calls to a plurality of cellular phones according to the location registration database. Further, the IMT2000 network performs a location registration to a public network corresponding to a plurality of cellular phones (PHS, PDC).
