消息处理方法、 装置及系统
本申请要求于 2010 年 9 月 30 日提交中国专利局、 申请号为 201010506138.0、发明名称为"消息处理方法、装置及系统"的中国专利申 请的优先权， 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信领域， 尤其涉及消息处理方法、 装置及系统。 背景技术
为了拓展无线通信系统的覆盖范围， 已经在传统无线网络中引入中继技术。 即在 eNB ( evolved Node B， 演进型基站）和 UE(User Equipment ，用户终端） 之间增加一个或多个 RN ( Relay Node,中继站）， RN负责将 eNB发出的无线信 号进行一次或多次处理并转发， 直到 UE接收到该无线信号。
很多时候， 用户设备通信时的位置是移动的。 比如一边走路一边接听或者 拨打电话， 再比如在行驶的车上接听或者拨打电话， 用户设备都会在保持通信 的状态下移动位置。 用户设备在保持通信的状态下移动位置， 常常会出现突然 通信终断的情况， 即掉话。
当 UE从 SeNB ( Source eNB , 源基站）控制的小区 1 ( celll )运动到 DeNB ( Dnor eNB, 控制基站）控制的小区 2 ( cell2 )， 再继续运动到 RN控制的小区 3 ( cell3 )。 其中， DeNB是 RN的 DeNB。 在 UE从一个小区移动到另一个小区 的过程中，需要进行信号的切换。 由于 UE经过 cell2的时间太短， 因此， 由 celll 到 cell2的切换失败。 为了使 UE能够保持通信， 于是， 在 UE进入 celB时， 需 要向 cell3进行连接重建。
因为 DeNB是 RN的 DeNB， 于是， DeNB的标识和 RN的标识相同， 所以 在 SeNB看来 Cell2和 Cell3这两个小区是由同一个基站控制的。 SeNB向 DeNB 发送一条切换请求消息， 所述切换请求消息中包含为 Cell2准备的 UE上下文信 息和为 Cell3准备的 UE上下文信息。 DeNB根据接收到的切换请求消息使 Cell2 准备好切换。 但是， 由于 Cell3实际上并不是 DeNB的小区， 而是 RN的小区， 因此， DeNB并不能使 Cell3准备好连接重建。 采用上述技术方案， UE在由 celll到 cell2切换失败后， 向 cell3请求连接 重建时， 连接重建会失败， UE由连接态回到了空闲态， 出现掉话。 由此， 由于 RN的引入， 使系统的连接重建成功率将会下降， UE业务的服务质量会随之降 低。 发明内容
