ABSTRACT:
A mobile communication device assists in a handover procedure between a first base station and a second base station using reliable and efficient techniques. The mobile device has a wireless transceiver and one or more processors coupled to the wireless transceiver. In one illustrative example, the one or more processors of the mobile device are operative to maintain a voice or data call over a traffic channel with use of the wireless transceiver; cause handover information of the handover procedure to be transmitted over a first control channel (e.g. SACCH) with use of the wireless transceiver during the voice or data call; and cause the same handover information of the handover procedure to be transmitted over a second control channel (e.g. FACCH) during the voice or data call. Further, the one or more processors may be operative to cause a message for the handover procedure to be transmitted in a layer-2 (L2) frame with use of the wireless transceiver during the voice or data call; and cause updated system information (e.g. an updated BA list) to be transmitted in the L2 frame with use of the wireless transceiver during the voice or data call.
