| 摘 要： | 提出一种高速铁路GSM专用网络的位置更新方法.该方法基于群用户管理,将移动用户划分为两个或两个以上的群,当列车到达新的位置区时,对不同的用户群依次进行位置更新,根据用户分组情况设定相应虚拟位置区,当延迟位置更新的群用户有新呼叫到达时,网络使用虚拟位置区进行寻呼以减少掉话率.性能分析结果表明,该方法有效的节省了信令开销和无线信道资源.

| Abstract: | This paper presents a new location updating scheme for high speed railway GSM private network which is based on group users＇ partition.The mobile users are divided into two or more groups,and when the train comes into a new location area（LA）,the different groups will execute location updating in turn.According to the MSs＇ group,it sets up the corresponding virtual LA,and when the MS has a new call arrived whose location updating is delayed,the network makes the paging by the virtual LA to decrease the call drop rate.Performance analysis results indicate that this scheme can save the signaling cost and radio channel resources effectively. |
