Executive Summary

This paper proposes a novel approach to Dynamic Channel and Packet Assignment (DCPA) scheme to serve efficient circuit-switching in voice traffic and packet-switching for Internet traffic communications in wireless cellular networks. The DCPA, as a distributed-controlled scheme, assigns channels or packet-slots to handoff and new calls based on their traffic type and channel status of cells. When the blocking probabilities of handoff and new calls in a cell become unacceptable, then the cell requests its neighboring cells to move appropriate free channels if possible. The rest of this paper presents the DCPA algorithm, uplink service access, and the frame structure used in packet-based communication.
