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. The basic access network executes signaling communication in which communication is controlled so as to be continuously switched, whereas the wireless access network executes data communications other than the signaling communication. According to the system of the present invention, networks can be continuously switched by setting multicast for temporarily flowing data to the basic access network.
