摘要：

Signaling process of vertical handoff with QoS support between GPRS and WLAN is developed. Schemes of Handoff Preparing Loop (HPL) and Layer 3 (Mobile IP layer) bi-direction connections between GPRS and WLAN are proposed in order to provide QoS guarantee. However, bi-direction connection will occupy more network resources. To solve this problem, a parameter "connecting lifetime" is introduced. The latency analysis and simulation results show that systems could achieve better performance in terms of handoff latency and outage probability.
