Abstract This paper presents two inter-layer hand-over models based on wireless mobile multimedia services including wide-band service and narrow-band service. One is bi-directional inter-layer hand-over model, the other is single-directional inter-layer model. The new call blocking probability and the hand-over call failure probability are analyzed. The QoS degradation of wide-band hand-over calls due to the inter-layer hand-over between macro-cell layer and micro-cell layer is presented in details. Also, an algorithm on channel allocation based on this hand-over policy is described. Finally, analysis and simulation results are compared to testify the hand-over policy submitted above.
