Abstract :
Call admission control (CAC) strategies which use queuing to prioritize handoff calls are considered. The system is assumed to be a single wireless cell serving two types of customers; narrowband (n-type) which require 1 channel and wideband (w-type) which require bw>l channels. Originating calls are assumed to be served on a "blocked calls lost" manner while handoff calls can queue for a finite time in an infinite sized buffer. Four different CAC strategies; Complete Sharing (CS), Guard Channels (GC), Threshold (TS), and Hold Back (HB) are applied to the system and the different performance measures of the system obtained. It is found that the GC strategy gives the least handoff call dropping. The HB strategy makes the system more fair to originating w-type calls while the TS strategy has the least server utilization.
