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.
使用动态计数器的GPRS位置更新性能
移动用户数量的增加导致了拥塞问题,并促使开发更有效的资源管理方案用于下一代无线系统。位置管理使网络能够在呼叫到达之间跟踪用户及其终端的位置。将移动用户的当前位置告知网络的操作称为位置更新。在3GPP 23.060中提出了READY timer (RT)机制来确定MS何时准备好从cell跟踪切换到RA跟踪。位置更新的主要思想是减少不必要的位置更新和分页开销。为了降低系统的位置更新和分页成本,提出了一种动态计数器机制。只有当移动设备移动到新的路由区域(RA)时才会进行更新。开发了一个基于Matlab的仿真器,用于研究定位更新性能和信令活动。初步结果表明,使用动态计数器可以减少平均位置更新。
