Simulation and modeling of mobile network case: ATUR 450 TM central region / Mohd. Yusof Ahmad

Mobile communication service in Malaysia began its operation in late eighties. Its technology has grown very fast and the mobile service operators have also grown from one operator to three at the moment. This Mobile Network Simulation project studies the problem of network congestion in ATUR 450 system. Although cell traffic statistic is the major problem faced by the ATUR 450 system, we believe that network congestion problem is very much related to this. ATUR 450 Systems work on frequency band of 452MHz to 466.5MHz which gives 180 channels throughout at 25kHz frequency separation. The system uses FSK modulation technique and their switching system uses the AXE exchange system (an Ericsson product). After knowing the ATUR 450 system a model buildup of the system was studied. From this model we proceeded with the building up of parameters and attributes necessary for use in a simulation package. We have decided to use Block Oriented Network Simulator (BONeS) Simulation Package for this project in which we are aware of the following factors in solving the above problem.
