The mobile station 12 is registered on a cellular network 16 and a mobile station identification number (MIN), that is, a telephone number of the mobile station is assigned thereto. Furthermore, in manufacturing, an electronic serial number (ESN) is assigned to the mobile station. The ESN is stored in a permanent memory of the mobile station ordinarily. As known by a corresponding enterpriser, the cellular network 16 is connected to the public switched telephone network for routing a call between a calling party of the cellular network 16 and a calling party of the public switched telephone network (PSTN) 15. <P>COPYRIGHT: (C)2007,JPO&INPIT |
