An adaptive handoff priority scheme is proposed for a packet switching multicode (MC)-CDMA cellular network supporting multimedia applications. The scheme jointly considers the physical, link and network layer characteristics, and gives service priority to handoff calls by exploiting the transmission rate adaptability of multimedia services over the available radio resources. Based on the proposed scheme, an admission region is derived for call admission control (CAC) and handoff management with quality of service (QoS) satisfaction for all multimedia traffic, where the QoS parameters include the wireless transmission bit error rate (BER), packet loss rate (PLR) and delay requirement. Simulation results substantiate the viability of the proposed scheme.
