Research on signaling activity and location upgrade performance for GPRS system / Rohana Mohammad Lawi

The General Packet Radio Service (GPRS) is a non-voice service that allows information to be sent and received across a wireless network. It supplements today's circuit switched data and short message service offered by GSM network. GPRS is the packet-oriented extension of GSM that involves overlaying a packet based air interface on existing circuit switched GSM network. In GPRS the information is split into separate but related "packet" before being transmitted and reassembled at the receiving end, thus an idle user will be always online within the coverage area. Location updating and signaling activities are a part of network management to evaluate performance for GPRS. In this project location updating and signaling activities had been studied and analyzed. A simulation tooi using MATLAB based on cellular 49 cells for 7 clusters had been developed. Various factors affect the signaling activity and location update such as mobile speed, cell radius and traffïc parameters had been considered. Initial simulation results shows location update counts and signaling activity count. From the simulation results, graphs had been plots to analyze and study GPRS system performance.
