In a wireless communication system (100), the base station controller (120) may detect that the mobile station (160) is operable in accordance with the wireless communication protocol based on information associated with the mobile station. In response to detecting at least one of condition of the system (100) suggesting a potential for improved system performance, the base station controller (120) may transmit a handoff message from the first base station (140) to the mobile station (160). The handoff message may notify the mobile station (160) to operate in accordance with the wireless communication protocol.Field of SearchHaving a plurality of contiguous regions served by respective fixed stationsChannel assignment Hand-off control Based upon a particular signal quality measurement Signal quality determined by bit error rate Channel assignment Adaptive Converting between protocols Conversion between signaling protocols Handoff Mobile assisted or initiated Handoff initiated by another source (e.g., target, user initiated, mobile switching center (MSC), or mobile telephone switching office (MTSO), etc.) Soft handoff Overlapping cells Between macro and micro cells | |
