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).
