Abstract
Mobile station communication architectures for supporting circuit and packet modes of operation and methods therefor, for example time division multiple access (TDMA) and general packet radio services (GPRS) in a cellular telephone handset. In one exemplary embodiment, the architecture includes a router and operating mode switch (108) coupled to an RF transceiver (112), a packet stack (102) coupled to the RF transceiver, a circuit stack (104) coupled to the router and operating mode switch and to the packet stack, the RF transceiver, and to the circuit stack coupled to the packet stack, and an interoperability entity (106) coupled to the router and operating mode switch and to the packet and circuit stacks.
