军用PCS系统中移动基站的位置登记策略研究

Research on location register strategy of mobile base station in military PCS system

移动基站技术是军用PCS系统的关键技术之一。在未来的战争中,通信基站根据需要可以自由移动,并有可能带大量用户共同移动,基站移动到新地方后能够快速和网络恢复连接,建立通信。基站的可移动性带来的关键问题是如何在网络中对移动基站进行拓扑更新和对用户群的位置进行快速有效登记。简要介绍了移动基站技术的概念后,以第二代数字移动通信系统GSM网络为基础,对移动基站的拓扑更新和用户群的成组位置登记提出了新的策略,补充和完善了原有的协议,使得新的协议更能够适应基站移动性的需求。

The mobile base station technique is the key technique in military PCS system. In the future war field, the Base Station may move freely when needed and the group of subscribers may likely move together. The Base Station can connect the network quickly when it moves to a new place and establish the communication. The key problem brought by the movement of BS is how to update the frame information of BS and of the group of subscribers rapidly and effectively. The Mobile Base Station technique is briefly introduced in this paper. Based on the 2nd mobile telecommunication system GSM, the new frame update strategy of the Mobile Base Station and the group of subscribers is put forward. It also renews and perfects the old strategy, which makes it adapt able to the requirement of the Base Station's moving.
