| 摘 要： | PCS系统中,用户漫游到非归属VLR覆盖区被呼时,系统将产生大量信令开销和数据库访问开销。该文为移动用户被呼提出了一种改进的缓冲呼叫算法来降低网络信令开销与数据库访问负荷和呼叫建立时延,建立了一种模型来分析其相关性能。与传统呼叫算法相比,改进呼叫算法能极大降低系统开销,具有较强的可行性。

| Abstract: | When deliver incoming calls to users visiting their nonresident Visitor Location Register (VLR) coverage, Personal Communication Service(PCS) networks will create significant signaling and database access load. In this paper, we propose an improved cache scheme to reduce signaling cost, delivery delay and access load during calls setup. An analytical model is applied to formulate the cost of the improved scheme. Our study indicates that the proposed scheme can significantly reduce the network costs compared with the traditional call setup approach. |
