ABSTRACT:
The present invention is a wireless communications system for simultaneously establishing a basic access network and a wireless access network using at least two kinds of wireless communication networks. In the basic access network, there are executed signaling communication for obtaining available network information based on the position information of a terminal and communication by SIP (Session Initiation Protocol) for executing exchange of a subscribe request signal between terminals and negotiation of communication. This arrangement makes it possible to connect between terminals by a media application on peer to peer.
