Abstract
In a wireless communication system including base transceiver stations connected to a wired network and wireless system terminals, the wireless system terminals are individually registered in a plurality of communicable base transceiver stations and at the same time set in a multilink connection state. Then, a base transceiver station that has a lower communication load and in a more stable communication state at current point in time is selected from among the multilink base transceiver stations connected to a wireless system terminal, thereby performing data communication with the wireless system terminal. With this arrangement, when an individual fixed connection is switched, no load is produced at the time of roaming, and stabilization of communication and balancing of communication loads resulting from switching of the base transceiver stations for use are realized. The throughput of the overall wireless communication system is thereby improved.
