ABSTRACT:
A two-way wireless communication system comprises a central authority in communication with a plurality of client devices via both a circuit switched data communication system and a packet switched data communication system. The packet switched communication system can assign packet switched network addresses to the client devices dynamically. Therefore, the central authority can be configured to send a circuit switched message, through the circuit switched data network, to a client device requesting the client device to register with the central authority through the packet switched data network.
