由移动性控制节点(21)对提供服务的服务提供装置和接受服务的提供的移动终端装置(10)之间的分组进行中继。
A packet between a service providing device for providing a service and a mobile terminal device (10) receiving the service is related by a mobility control node (21).
另外，当在其移动性由各个移动IPHA管理的终端之间执行会话移交时，很难使IETF标准正常地应对上行链 路分组。
Moreover, when performing a session handover between terminals which are mobility-managed by separate Mobile IP HA, it is impossible to normally handle an Uplink packet by the IETF standard technique.
该算法在进行网络选择时不仅考虑到网络的负载情况，还充分考虑了发起会话的业务属性、终端的移动性以及终端在网络中所处位置的不同。
By this algorithm, the most suitable network for each session can be selected according to network load conditions, service attribute, mobility and different locations of terminal.
然而，终端的移动性，无线链路的低可靠性以及无线带宽资源的有限性等条件限制使得无线接入成为大数据量传输的瓶颈。
However, the mobility effect, unreliable wireless channel condition and limited available wireless spectrum resources are the bottleneck for large traffic transmission.
MM子层的主要功能是来支持用户终端的移动性，例如告知网络侧关于用户的位置并且保证用户身份的私密性。
The main function of the Mobility Management sublayer is to support the mobility of user terminals, such as informing the network of its present location and providing user identity confidentiality.
