GPRS location update performance using dynamic counter

Abstract

The increasing population of mobile users leads to congestion problems and motivates the development of more efficient resource management schemes to be use in next generation wireless system. Location management enables the network to track the locations of users and their terminals between call arrivals. The operation of informing the network about the current location of the mobile user is known as location update. A READY timer (RT) mechanism was proposed in 3GPP 23.060 to determine when MS ready to switch from cell tracking to RA tracking. The main idea of location updation is to reduce the unnecessary location update and paging cost. We propose a dynamic counter mechanism to reduce the location update and paging cost in this system. The updation takes place only when the mobile moves to the new routing area (RA). A simulator based on Matlab, which can study the location updation performance, and signalling activities was developed. Initial result shows that the average location updation could be reduced by using dynamic counter.
