Over the last decade, deployment of mobile communications has been phenomenal. The integration of mobile communications and computing results in a new distributed network, referred to as a mobile computing system. Multimedia mobile networks are new mobile communication systems which will enable users to economically transfer any form of information between any desired locations at any time.Mobility management, i.e., how to track the mobile users that move from place to place is one of the most important issues in multimedia mobile networks. The mobile users are the subscribers that use either the automobile or hand held telephones or portable computers to send and receive calls.There are two kinds of mobility managements : static schemes and dynamic schemes. In the existing mobile networks, the static schemes are used. Under the static schemes, however, cannot catch the moving patterns of mobile users.Dynamic location management methods are proposed for dealing with the problems of static schemes. In dynamic schemes, the size of a location area is determined dynamically according to the changes of mobility and calling patterns of mobile terminals.In the research, we study both the static and dynamic mobility management methods. We have proposed the optimal dynamic mobility management method for the multimedia mobile networks. Other important contribution is the novel analytic model firstly established for the performance study of dynamic and static mobility methods for multimedia mobile networks with real network architectures. The third contribution is the proposed effective database management method for the mobility management in multimedia mobile networks.Furthermore, we consider the multimedia mobile networks as an extension to distributed/parallel systems. Many works related to distributed and high-performance parallel systems have been conducted.

在过去的十年中，移动通信的部署非常出色。移动通信和计算的集成导致一个新的分布式网络，称为移动计算系统。多媒体移动网络是新的移动通信系统，它将使用户在任何时间之间在任何所需的位置之间经济转移任何形式的信息。MobilityManagement，即如何跟踪从地点到地点移动的移动用户是多层移动网络中最重要的问题之一。移动用户是使用汽车或手持电话或便携式计算机发送和接收呼叫的订户。有两种移动性管理：静态方案和动态方案。在现有的移动网络中，使用静态方案。但是，在静态方案下，无法捕获移动用户的移动模式。提出了用于处理静态方案问题的漫画位置管理方法。在动态方案中，位置区域的大小是根据移动性和移动终端的调用模式动态确定的。在研究中，我们研究了静态和动态移动性管理方法。我们为多媒体移动网络提出了最佳的动态移动管理方法。另一个重要的贡献是针对具有真实网络体系结构的多媒体移动网络的动态和静态移动方法的性能研究最初建立的新型分析模型。第三个贡献是在多媒体移动网络中提出的用于移动性管理的有效数据库管理方法。FURTHERMORE，我们将多媒体移动网络视为分布式/并行系统的扩展。已经进行了许多与分布式和高性能平行系统有关的工作。
