Mobility management , has become one of the challenging topics in mobile computing . it is significant in mobile computing that rational , effective and optimized mobility management schemas are conceived and their algorithms are proved to be feasible according to some strict theories 设计合理、高效、优化的移动台的移动性管理策略,并给出行之有效的算法及严密的理论证明,在移动计算中是十分重要的。
It is able to keep the communications when the mobile terminals move from one area to another . the goal of handover management is to provide a seamless connection qos guarentees for kinds of services when a handover accours . recently , there are kinds of typical handover thechnologies , such as those in cellar network , those in mobile ip , and so on 切换管理作为移动性管理中的一项关键技术,要确保移动用户在通信过程中从一个节点覆盖区移动到另一节点覆盖区时通信的连续性,实现移动通信的无缝隙覆盖,为各种业务模型提供可靠的通信质量。
