PROBLEM TO BE SOLVED: To provide a system which correctly verifies whether an authenticity of a telephone number reported by a request from a wireless device belongs to the wireless device. SOLUTION: The wireless device and a computing system of a receiving side communicate through a network of a communication enterprise. A request of a service is submitted to the computing system of the receiving side and the computing system of the receiving side returns an authentication key back. The authentication key is routed as being related to the wireless device by using the telephone number stated clearly in the request of the service. However, the authentication key is sent through a different data transport mechanism. The wireless device verifies through a proper communication that the wireless device submits the request and receives a response. As a result, the telephone number is verified as being related to the wireless device. COPYRIGHT: (C)2004,JPO
