In a communication method between the Internet and a mobile station, when transmitting an outgoing signal to the Internet, a private address is assigned to the mobile station which has transmitted the outgoing signal to a switching device. The private address is selected from a group of private addresses uniquely assigned to the switching device. A first correspondence of the private address and the ID number of the mobile station is stored. After converting the private address to a unique network address as a source address, a second correspondence of the unique network address and the private address is stored. The first and second correspondences are used to transfer an incoming signal received from the Internet to the mobile station through a switching device. |
