Handoff Call Control Scheme in a Multi-Frequency CDMA Mobile Communication Systems

摘要

This paper addresses handoff management in a multi-frequency CDMA system with qnon-uniform traffic loads over cells. We propose a new handoff scheme, called here the adaptive handoff management (AHM), in which the inter-cell hard handoffs, not only incurring equipment cost burden but also degrading call quality, are totally removed. Also contained in the AHM is the call control capability of adaptively reflecting the traffic environment Traffic and mobility analysis is first conducted on a single isolated cell with two co-centered circle boundaries, thereby rendering two key performance measures. Computational experiments are conducted to illustrate the superiority of AHM in two key performance criteria.
