Abstract :
In this paper, we propose a virtual guard channel (VGC) scheme for handoff calls in integrated voice/data wireless networks. By utilizing the multi-channel capability of data service, the proposed scheme can provide better performance in quality of service (QoS) provisioning and utilize the limited channel resources more efficiently compared with the conventional guard channel (GC) scheme.
