发明名称 SUPPORTING BOTH PACKET AND CIRCUIT-BASED WIRELESS NETWORKS
摘要 <p>Middleware (24) may accomodate both packet data and circuit data services (20) in the same cellular telephone. A cellular telephone may travel between networks that are packet and circuit data service based. A protocol middleware (24) may determine whether packet data services are available and, if so, may determine the mobility management state of the system. Depending on the mobility management state of the system, inappropriate applications may be closed or suspended.</p>
