Abstract
To address the need for improved public long code mask (PLCM) management during handoffs, embodiments of the present invention enable a mobile station (MS) () to use a different PLCM when communicating with the target base station (BS) () than is used when communicating with the serving BS (). The embodiments provide for signaling between the serving and target BSs, via the mobile switching center (MSC) (), by which the target BS can provide a new PLCM for communication between the MS and the target BS. By allowing each target BS to allocate and communicate PLCMs for hand-off MSs, today's PLCM sharing, and thus the cross-talk problem, can be avoided.
