Cellular communications systems require handoff to provide seem less service for users moving across cells. Code Division Multiple Access [CDMA] systems support soft handoff where a mobile station [MS]starts communication with the target base station [BS] without disconnecting from the serving BS. Rejection of soft handoff request due to resource/channel shortage causes forced termination of anongoing real time call, which is a severe problem than blockage of new call from user satisfaction point of view. Therefore it is necessary to employ some specific schemes to prioritize handoff requests over originating calls. Several schemes have been proposed in literature to prioritize handoff. This article provides a comprehensive survey of soft hand off prioritization schemes for CDMA systems. Our goal is to provide a broad classification and through discussion of existing soft handoff schemes and compare them in terms of performance and complexity. Finally the paper concludes on the state off current research and points out some of the key issues that need to be addressed in the context of soft handoff for future cellular networks. |
