    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 controller (118) controls functions related specifically to radiotelephone signalling in a communication system. The controller (118) is physically dislocated from a switch (112) which performs all necessary routing of voice information from radiotelephone system-to-radiotelephone system and radiotelephone system-to-public switched telephone system (PSTN, 100). The controller (118) interfaces the switch (112) via an ISDN-type connection, essentially accessing the switch (112) transparently. This transparent access allows for common, generic switches (Class 5 switches for example) having predetermined user features such as Call Waiting, 3-Way Calling, etc. to be employed. Users of the radiotelephone system (125), via radiotelephone signalling processing by the controller (118), can access and utilize the predetermined features of the switch (112) as required.
