Radio resource and mobility management in GPRS network

The General Packet Radio Service (GPRS) is a complex data network which upgrades current second generation GSM networks, offering true high-speed Internet (IP) and X.25 network connectivity over existing GSM cellular networks. The key benefits of GPRS are better use of radio and network resources and completely transparent IP support. The increasing population of mobile users leads to congestion problems in these systems, and motivates the development of more efficient management schemes. Although GPRS offers a major improvement in spectrum efficiency, the capability and functionality compared with today's non-voice mobile services, there are still some key limitations with GPRS such as the transit delay, speeds which are much lower in reality and limited modem of operation. This paper overviews radio resource and mobility management such as location management and handoff management and discusses some of the key problems and method of overcoming these limitation and management problems in the GPRS network. A simulator based on Matlab which can study the location updating was developed in this GPRS system. The initial simulation shows the updating based on cell distance with various speeds.
