Channel assignment for GSM half-rate and full-rate traffic

Global System for Mobile Communications (GSM) supports full-rate and half-rate calls. In this paper, we propose analytical and simulation models to study the performance of four channel assignment schemes for GSM half-rate and full-rate traac. Our study indicates that among the four schemes, the repacking scheme has the best performance for mixing half-rate and full-rate traac. We also observe that good performance is expected if the standard derivation of the cell residence time for a mobile station is large.
