Performance of Personal Portable Radio Telephone Systems with and without Guard Channels

摘要

We present and compare three call handling schemes for a base station which can handle two types ot calls(originating and prioritized handoft calls) and serves these calls under the blocked-calldelayed basis.Delayed calls are assumed to be stored in a finite storage buffer.One:schelne exclusively allows handoff calls to be stored and to use a fixed number of guard channels.The other two schemes without guard channels allow both types of calls to be stored and prioritized handoff calls to pushout origination calla if the buffer is full.For these three schemes,the blocking probabilities and delay distributions of both types of calls are compared,and a boundary for call handling schemes between with and without guard channels is found.
