Establish a Methodology for Testing and Optimizing GPRS Performance Case Study: Libya GSM

The main goal of this paper is to establish a methodology for testing and optimizing GPRS performance over Libya GSM network as well as to propose a suitable optimization technique to improve performance. Some measurements of download, upload, throughput, round-trip time, reliability, handover, security enhancement and packet loss over a GPRS access network were carried out. Measured values are compared to the theoretical values that could be calculated beforehand. This data should be processed and delivered by the server across the wireless network to the client. The client on the fly takes those pieces of the data and process immediately. Also, we illustrate the results by describing the main parameters that affect the quality of service. Finally, Libya’s two mobile operators, Libyana Mobile Phone and Al-Madar alJadeed Company are selected as a case study to validate our methodology. Keywords—GPRS, performance, optimization, GSM
