Description

辅助主小区的调整方法以及基站
本申请要求于 2012 年 6 月 28 日提交中国专利局、 申请号为 CN 20121 0218817. 7 , 发明名称为 "辅助主小区的调整方法以及基站" 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
本发明涉及通信领域，尤其涉及一种辅助主小区的调整方法以及 基站。
背景技术
随着移动通信系统的发展，通信系统能够提供的传输速率和服务 质量越来越高， 用户也对传输速率提出了更高的要求。 为了在不大幅 增加配置带宽的情况下， 保证多数用户的速率， 同时为一部分用户提 供更高的吞吐量， 第三代合作伙伴计划 （ The 3rd Generation Partnership Project , 简称 3 GPP ) 引入了 载波聚合 ( Carrier Aggregation , 简称 CA ) 技术。 载波聚合是指用户终端 （ User Equipment , 简称 UE ) 可以同时使用多个成员载波 （ Component Carrier, 简称 CC ) 进行上下行通信， 从而支持高速数据传输。 当用 户速率降低时， 可以释放一些成员载波， 只保留一个驻留载波， 释放 出来的传输资源可以供其它用户使用， 从而达到灵活、 动态的目的。
载波聚合中， 主小区 （primary cell , 简称 P-Cell ) 承担安全、 切换、 上行物理控制信道承载等工作， 其它参与聚合的小区称为成员 小区 （ Secondary Cell , 简称 S-Cell ) , 成员小区只承担数据传输的工 作，不涉及安全、切换等。对于基站内部的小区聚合，只有一个 P-Cell , 承载所有聚合小区的上行物理控制信道。 但是对于基站间的小区聚 合， 每个基站使用各自的主小区。 但由于 UE的管理功能只能由一个 基站下的主小区承担， 如切换管理、 安全控制等， 所以， 其它基站下 的主小区称为辅助主小区， 记为 PCell*。 相应地， PCell所在的基站 ( evolved NodeB , 简称 eNB )称为主基站 ( Primary evolved NodeB , 简称 PeNB ) , 其它 PCell*所在的 eNB称为辅基站（ Secondary Radio Bearer , 简称 SeNB ) 。 随着用户终端的移动， 各个小区相对应用户 终端的信号质量也会发生变化，因此 PCell*的信号质量也往往不再可 靠。

实施例一 本实施例提供一种辅助主小区的调整方法， 如图 1 所示， 该方 法包括：
步骤 101、 主基站确定更改由辅基站提供服务的第一辅助主小 区， 并从所述辅基站提供服务的小区中选择第二辅助主小区。
作为本发明的一种实施方式， 按照网络侧的测量配置， UE不断 测量 SeNB承载的各个小区的无线信号质量，并将测量结果通过测量 汇报消息上报给主基站 PeNB ,主基站接收来自 UE的测量汇报消息， 如图 2所示， 其中， 测量汇报消息中包含所述 UE测量辅基站中各个 小区的无线信号质量的测量结果。
PeNB 根据测量汇报消息中 UE 测量的无线信号质量的测量结 果， 来判断 SeNB中原有的 PCell* , 即第一辅助主小区的信号质量是 否可靠。 若仍然可靠， 则继续使用第一辅助主小区； PeNB 如果发现 原有的 PCell*的信号质量不再可靠， 或者其它原因， PeNB 需要更改 SeNB中的 PCell*。 PeNB根据测量结果从 SeNB中各个小区中选择新 的 PCell* , 即第二辅助主小区， 示例性的， PeNB从 SeNB 中各个小 区中选择信号质量最好的小区作为第二辅助主小区。
进一步的， 在根据所述测量结果选择新的辅助主小区之后， 本 实施例的方法还包括：
所述主基站为所述 UE 在所述新的辅助主小区中分配物理上行 链路控制信道 ( Physical Uplink Control Channel, 简称 PUCCH )资源， 并 4汙生所述新的辅助主小区所对应的安全密钥 K-eNB*。
在 PeNB根据测量结果从 SeNB 中各个小区中选择新的 PCell* 之后， PeNB还接着为 UE在新的 PCell*中分配 PUCCH资源， 以及衍 生 PCell*所对应的安全密钥 K-eNB*。
步骤 102、 所述主基站发送第一消息至所述辅基站， 用于请求所 述辅基站调整所述辅助主小区， 所述第一消息中包括所述第二辅助主 小区的标 i只。
PeNB发送第一消息至 SeNB , 以告知 SeNB主基站所选择的第 二辅助主小区作为新的 PCell* , 辅基站根据第一消息调整使用的辅助 主小区为第二辅助主小区， 其中， 所述第一消息中包括第二辅助主小 区的标 i只。
进一步的， 第一消息中还包括 PeNB分配的 PUCCH资源和衍生 的安全密钥 K-eNB*。 第一消息中携带 PUCCH资源， 用于使所述新的 PCell*为 UE预留所述 PUCCH资源。 此外， 第一消息中还可包含一些 其他的信息， 如用户终端标识 （UE ID ) 等， 以使 SeNB得知配置的 PUCCH资源所属的使用者。
进一步的， 在主基站发送第一消息至所述辅基站之后， 所述主 基站发送第二消息至所述 UE之前， 还包括：
所述主基站接收来自所述辅基站的辅助主小区修改响应消息。
SeNB在接收到第一消息后， 还向 PeNB发送辅助主小区修改响 应消息， 以告知 PeNB辅基站已收到第一消息并得知了新的 PCell*。
步骤 103、 所述主基站发送第二消息至所述 UE, 用于请求所述 UE使用所述第二辅助主小区。
具体的， PeNB在接收到辅助主小区修改响应消息后， 发送第二 消息至所述 UE, 以使 UE改变现有的 PCell* , 其中， 第二消息可具体 为 PCell*更改指令， 第二消息中包含有新的辅助主小区的标识以及 PeNB分配的 PUCCH资源。 UE在接收到第二消息后， 就可以使用第 二辅助主小区了。 需要说明的是， PeNB 不需要将衍生出的安全密钥 K-eNB*告知 UE, 原因是 UE可以根据 UE ID , 自己完成衍生工作， 生成完全相同的 K-eNB*。
进一步的， 在所述主基站发送第二消息至所述 UE之后， 本实施 例的方法还包括： 所述 UE在接收到所述第二消息后，判断与所述新的辅助主小区 是否处于上行同步状态，
若没有， 则向所述新的辅助主小区发起随机接入， 以接入所述 辅基站。
UE收到第二消息， 即 PCell*更改指令后， 可以向 SeNB发起随 机接入，也可以不发起，这一步骤是否需要，取决于 UE在新的 PCell* 中是否还处在上行同步状态， 如果上行仍然是同步的， 就不需要发起 随机接入， 否则就需要随机接入。 UE 向新的 PCell*发起随机接入成 功后， 再向 PeNB指示第二辅助主小区生效， 或者由 SeNB向 PeNB 指示第二辅助主小区生效， 就可以使用新的 PCell*传输控制信令了。
本实施例的辅助主小区的调整方法，通过 PeNB先与 SeNB协商 并选定第二辅助主小区， 然后 SeNB在第二辅助主小区上为该 UE预 留 PUCCH资源， PeNB与 UE交互后， UE就可以直接使用 SeNB上 第二辅助主小区的物理资源了， 实现了辅助主小区更改的实时性， 提 高了通信效率。
实施例二
本实施例提供一种辅助主小区的调整方法， 如图 3 所示， 该方 法包括：
步骤 201、 辅基站确定更改由辅基站提供服务的第一辅助主小 区， 并从所述辅基站提供服务的小区中选择第二辅助主小区。

SeNB 根据测量汇报消息中 UE 测量的无线信号质量的测量结 果， 来判断 SeNB中原有的 PCell* , 即第一辅助主小区的信号质量是 否可靠。 若仍然可靠， 则继续使用第一辅助主小区； SeNB 如果发现 原有的 PCell*的信号质量不再可靠， 或者其它原因， 需要更改 SeNB 中的第一辅助主小区。 SeNB根据测量结果从 SeNB 的各个小区中选 择新的 PCell* , 即第二辅助主小区， 示例性的， SeNB 可以从各个小 区中选择信号质量最好的小区作为第二辅助主小区 PCell*。
进一步的， 在根据所述测量结果选择第二辅助主小区之后， 本 实施例的方法还包括：
所述辅基站为所述 UE在所述新的辅助主小区中分配 PUCCH资 源。
在 SeNB根据测量结果从 SeNB 中各个小区中选择新的 PCell* 之后， SeNB还接着为 UE在新的 PCell*中分配 PUCCH资源， 以为 UE使用第二辅助主小区做准备。
步骤 202、 所述辅基站发送第一消息至所述主基站， 用于指示调 整所述辅助主小区， 所述第一消息中包括所述第二辅助主小区的标 识。
SeNB发送第一消息至 PeNB , 其中， 第一消息中包括第二辅助 主小区的标识， 以使 PeNB得知该新的 PCell *。 需要说明的是， PeNB 在接收到第一消息后， 可以不用为衍生第二辅助主小区所对应的安全 密钥 K-eNB*， 仍然沿用先前的安全密钥， 这样可以简化调整的流程， 且先前的安全密钥没有在 PeNB与 SeNB之间进行过传递， 因此安全 性较高。
此外， PeNB在接收到第一消息后也可以为衍生第二辅助主小区 所对应的安全密钥 K-eNB*， 这样就需要第一消息中包括安全密钥请 求信息， 以使 PeNB衍生第二辅助主小区所对应的安全密钥 K-eNB *。 此外，第一消息中还可包含一些其他的信息，如用户终端标识（UE ID ) 等。
进一步的， 在辅基站发送第一消息至主基站之后， 辅基站发送 第二消息至所述 UE之前， 还包括：
所述辅基站接收来自所述主基站的辅助主小区修改响应消息。
PeNB在接收到第一消息后， 还向 SeNB发送辅助主小区修改响 应消息， 以告知辅基站已收到第一消息并得知了新的 PCell*。 进一步 的， 若第一消息中有安全密钥请求信息， 则辅助主小区修改响应消息 中还包括 PeNB衍生第二辅助主小区所对应的安全密钥 K-eNB*。
步骤 203、 所述辅基站发送第二消息至所述 UE, 以使所述 UE 使用所述第二辅助主小区。
具体的， SeNB在接收到辅助主小区修改响应消息后， 发送第二 消息至所述 UE, 以使 UE改变现有的 PCell* , 第二消息中包含有第二 辅助主小区的标识以及 SeNB分配的 PUCCH资源。 UE在接收到第二 消息后， 就可以使用第二辅助主小区了。 需要说明的是， 若 PeNB衍 生了第二辅助主小区所对应的安全密钥 K-eNB*， 则 UE在接收到第 二消息后， 根据 UE ID 自行衍生该安全密钥。
进一步的， 在所述辅基站发送第二消息至所述 UE之后， 本实施 例的方法还包括：
所述 UE在接收到所述第二消息后，判断与所述第二辅助主小区 是否处于上行同步状态，
若没有， 则向所述第二辅助主小区发起随机接入， 以接入所述 辅基站。
UE收到第二消息， 可以向 SeNB发起随机接入，也可以不发起， 这一步骤是否需要， 取决于 UE在新的 PCell*中是否还处在上行同步 状态， 如果上行仍然是同步的， 就不需要发起随机接入， 否则就需要 随机接入。 UE向新的 PCell*发起随机接入成功后， 再向 SeNB指示 新的 PCell*生效， 或者由 PeNB向 SeNB指示新的 PCell*生效， 就可 以使用第二辅助主小区传输控制信令了。
本实施例的辅助主小区的调整方法， SeNB通过 UE上>¾的无 线信号质量的测量结果选择新的 PCell* , 然后 SeNB在新的 pcell*上 为该 UE预留了 PUCCH资源， SeNB与 UE交互后， UE就可以直接 使用 SeNB上新 Pcell*的物理资源了， 实现了辅助主小区更改的实时 性， 提高了通信效率。

SeNB 根据测量汇报消息中 UE 测量的无线信号质量的测量结 果， 来判断 SeNB中原有的 PCell* , 即第一辅助主小区的信号质量是 否可靠。 若仍然可靠， 则继续使用第一辅助主小区； SeNB 如果发现 原有的 PCell*的信号质量不再可靠， 或者其它原因， 需要更改 SeNB 中的第一辅助主小区。 SeNB根据测量结果从 SeNB 的各个小区中选 择若干个 PCell*作为候选辅助主小区， 示例性的， SeNB 可以按照信 号质量从各个小区中选择信号质量较好的若干个 PCell*。
进一步的， 作为本发明的一种实施方式， 如图 6 所示， 在根据 所述测量结果从所述辅基站中各个小区中选择若干个候选辅助主小 区之后， 本实施例的方法还包括：
