Abstract
The present invention aims to perform communication between the wireless terminals by adopting the existing networks and by avoiding the congestion on the network. The terminal location databases set at various networks control the position information of the wireless terminals. According to one of the steps in the method of the present invention, a wireless terminal inquires a terminal location database for the position information of a destination wireless terminal. Then, as for the next step, the wireless terminal receives a reply from the terminal location database regarding the position information of the destination wireless terminal. As for the following step, the wireless terminal communicate to the destination wireless terminal.
