Abstract
A distributed processing architecture for a wireless communication system in which handover intelligence is distributed between the Base Station Subsystem (BSS), Base Station Controller (BSC) and Base Transceiver System (BTS). Mapping between air-interface traffic (Um) channels and Abis-interface traffic channel connections is dynamically assigned. This permits the BTS to manage information concerning active frequency channel assignments, individual channel measurement data, and intra-cell handover. The BTS therefore need only escalate the handover decision to the BSC level when the situation requires inter-cell handover.
