| 摘 要： | 提出了一种多层次的移动性管理策略，并从数据库所需存储容量、位置更新和呼叫所带来的数据库访问频率以及网络通信代价几方面将这种策略和双层管理策略作了比较，结果表明前者更适用于用户密度，较大的环境，因此是未来通信移动性管理发展的一个方向。

| Abstract: | A mobility management strategy based on the multi-level distributed database structure ispresented. A comparison is made between this mobility strategy and the commonly used two-levelstrategy in the database memory capacity required, the database access frequency and communication cost incurred due to location updating and calling. The resulesshow that the former is better suited to the case when the user density is high. |
