摘　　要：提出了一种基于前转指针的平滑主动位置恢复方案,以位置数据库的处理能力和有线信令消耗,换取无线资源的节省。无需终端的周期性位置更新操作,即可使移动通信系统获得对位置数据库的容错能力。同时,在故障期内采用前转位置指针,使移动用户感知不到HLR故障的存在,具有持续的出呼叫能力。A proposal of smooth aggressive location restore by forwarding pointer is given in this paper. In this proposal, radio resources have been saved with the costs of wire signal and operation of location databases. A mobile communication systems robustness in case of a location-database failure is improved without the need for periodic location update operations. Meanwhile, a chain of forwarding location pointers has been used during the period of HLR failure. So mobile stations are unconscious of the failure of HLR, and mobile subscribers can always make outgoing call.
