Efficient Radio Resource Allocation in a GSM and GPRS Cellular Network

摘要

This paper investigates the effect of various resource allocations in a GSM/GPRS cellular network. The most efficient resource allocation is found as a function of the circuit switched voice and packet switched data load. The Grade of Service and average packet delay is investigated as a function of the load, packet size and call duration. Additionally, the feasibility of using voice over Internet Protocol as opposed to circuit switched voice is investigated as a means to increase subscriber capacity per base station. The work is motivated firstly by Jhe complexity of having both circuit switched and packet switched connectivity on GSM/CJPRS mobile cellular system and secondly that an exclusively packet based access on GSM/GPRS has the potential to increase the efficiency of resource utilisation by suitably varying the channel allocation to exploit the characteristics of voice and data traffic.
