Abstract

This paper considers three circuit allocation schemes for half- and full-rate connections in the Global system for Mobile Communications (GSM): best fit, repacking, and fair repacking. Analytic numerical methods are used to investigate each scheme´s blocking probability behavior. The analysis is based on a reduction of the state space to a manageable size. Fair repacking is found to be the fairest and most efficient. However, the best-fit scheme, while being somewhat less efficient and fair, is simpler to implement. The effect on quality of service (QoS) of voice dropouts related to intracell handover (repacking) was found to be negligible
