    Abstract: A wireless communication system ( 10 ) uses communications bridging functions to establish redundant communication paths ( 32, 34, 44, 46 ) between redundant radio access network session clients ( 36, 38 ), a core system 16 and a base transceiver station ( 40 ). The system ( 10 ) carries out a handoff or reallocation of call control from one of the radio access network session clients ( 36, 38 ) to another one of the radio access network session clients ( 36, 38 ) based on the integrity of the redundant communication paths ( 32, 34, 44, 46 ).

    Abstract: A communication system (100) having packet and circuit switched networks (102 and 101) provides connection between at least a first and a second end users by establishing a call connection via a radio access network (105), establishing a control channel associated the call connection between radio access network (105) and packet switched network (102) through a first packet switched connection, selecting one of packet and circuit switched networks (101 and 102) for establishing a traffic channel associated with the call connection, and routing the traffic channel through said selected network while maintaining the control channel through packet switched network (102).
