Title: GSM Cell traffic Channels’ Load Redistribution
Authors: Bruku, Kofi Wilfred
Issue Date: 18-Nov-2012
Abstract: User behaviours such as mobility, mean holding time, mean inter-arrival time of calls and cell parameters such as the number of traffic channels are factors that affect the blocking probability and grade of service (GoS) of GSM cells. Depending on the value of these parameters, individual cells (and the GSM system as a whole) may become congested leading to performance degradation, customer frustration and revenue loss on the operators’ part. A careful study of these factors and the necessary adjustments improve the blocking probability and GoS of the system. A simple model is developed to investigate the effect of these factors on the blocking probability and GoS of the GSM cell and the GSM system as a whole. Aspects of user behaviour investigated are the user mobility, mean holding time and mean intearrival time of calls to the cell. The cell parameter investigated is the number of traffic channels at the air interface of the cell . The model is also used to study the effects of cell load redistribution. The effect of redistributing the load of a spontaneously congested cell to freer neighbouring cells was found to improve upon the overall GoS of the system.
