Analysis of Improved Wireless Channel Allocation Scheme

With the Widly applicable of GPRS/GSM mobile access network,the efficient channel allocation scheme has shown importance in supporting the quality of network service. In view of GSM/GPRS network limitations which are a low utilization about wireless resource and channel,based on the analysis of the typical channel allocation schemes such as fixed channel allocation scheme,dynamical channel allocation scheme and hybrid channel allo-cation scheme for GSM/GPRS networks,analyses an improved channel allocation scheme,channel re-allocation and de-allocation scheme. Numerical results show that new scheme not only significantly decreases the voice call blocking probability and the average GPRS packet transmission time,but also slightly increases the channel utilization.
