Description

一种管理微小区和宏小区的定时差信息的方法 本申请要求于 2012 年 1 月 21 日提交中 国专利局、 申请号为 201210019829.7、 发明名称为"一种管理微小区和宏小区的定时差信息的方法"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
本发明涉及通信技术领域， 尤其涉及一种管理微小区和宏小区的定时 差的方法、 汇集节点、 微小区基站及系统。
背景技术
为了能够满足通信网络无缝覆盖的要求， 现有技术中提出了异构网络 (Heterogeneous Network, Hetnet)。 Hetnet网络是由不同大小、 类型的小区 一起构成的网络，如宏小区（Macro cell)、微小区（Micro cell)和微微小区（Pico Cell)等， 宏小区的基站下管理多个小区， 微小区和微微小区等的基站只管 理一个小区。
在 WCDMA通信网络系统中， WCDMA系统中下行链路共有 512个扰 码 （Primary scrambling code, PSC) ， 每个小区分配一个 PSC作为小区的 标识参数之一。 而 WCDMA通信系统的微小区使用的 PSC数量有限， 这样 和宏小区有重叠覆盖范围的微小区会有多个微小区共用一个 PSC， 且 UE 在对相邻小区进行测量时不具有读取相邻小区的除 PSC信息外的其它标识 参数的功能。 为了保证用户设备 (User Equipment, UE)从宏小区成功切换到 和宏小区有重叠覆盖范围的 目标微小区， 管理该宏小区的 RNC ( Radio Network Control, 无线网络控制器） 在向管理该目标微小区的网关发送切 换消息后， 管理该目标微小区的网关在只能获取目标微小区的 PSC信息、 目标微小区和该宏小区的定时差信息的情况下， 利用具有相同 PSC的微小 区和该宏小区的定时差的唯一性等信息筛选出 目标微小区， 对 UE 进行切 换。
但是目标微小区和宏小区的基站的帧定时可能会发生漂移， 因此目标 微小区的基站 (Base Station, BS)的帧定时与宏小区的基站的帧定时之间的 定时差也可能发生改变， 从而导致宏小区和具有相同 PSC的微小区之间的 定时差可能相同。 在利用 目标微小区的 PSC、 目标微小区和宏小区的定时 差等信息来确定目标微小区时， 具有相同 PSC的微小区和 UE所处的宏小 区的定时差信息不具有唯一性， 从而导致微小区的网关无法确认目标微小 区， 进而导致 UE无法切换到目标微小区。
