Description

邻区列表自动维护方法及*** 技术领域
本发明涉及一种网络侧网元的邻区列表维护技术， 尤其涉及一种邻区 列表自动维护方法及***。 背景技术
在通信***中， 为了减少网络建设和运营的成本， 传统的路测是用人 工对需要监测和优化的区域进行测试， 而在基于下一代网络的演进***中， 降低对传统路测的依赖以及通过更智能的网优工具是必要的， 因此， 自动 实现路测终端 （也即用户设备） 的测量信息的收集并最小化人工路测的需 求， 是非常有益的。 另一方面， 利用用户设备 ( UE , User Equipment )的测 试结果可以自动地对网络进行优化， 以及对网络运行有全面的了解。 因此， 在长期演进 ( LTE, Long Term Evolution )***中提出了最小化路测（ MDT, Minimise Drive Test ) 的技术研究， 同时该技术也可运用于通用移动通信系 统 ( UMTS , Universal Mobile Telecommunications System ) 中。 实现方式基 于基站（ eNB )测量控制和 UE将测量信息上报机制， 图 1为 MDT的架构 示意图， 如图 1 所示， 网络管理***及无线接入网 （RAN, Radio Access Network )位于移动网的网络侧， RAN中包含 eNB, 由 RAN对 UE进行测 量控制， 如通过空口消息等将测量控制信令发送给 UE, UE接收到测量控 制信令后， 执行路测， 并将路测得到的相关信息上报至 RAN, 并由 RAN 上报至网络管理***， 网络管理***根据路测相关信息进行网络优化等操 作。具体的，上述 UE的路测主要包含 UE连接态下的即时上报、空闲（ IDLE ) 态下的日志上报以及连接态下的日志上报三种类型。
另外， 移动用户的服务连续性是蜂窝移动通信***的一个基本特征， 而用户设备服务小区的切换是保证服务连续性的主要手段。 为了便于用户 设备进行切换， 移动通信***需要给每个小区配置邻接关系， 以便网络侧 将邻区信息通知至用户设备， 用户设备对邻区进行测量后上报测量结果， 再由网络侧指示用户设备切换到某一邻区。 某个小区周围有哪些邻区不仅 与小区距离有关， 而且与小区所处的无线环境密切相关。 由于无线环境错 综复杂， 尤其是高层建筑密集的城区环境， 在网络规划初期很难确切判断 某个小区应该配置哪些邻区。 还有一些如***中新增加了一个小区或者小 区属性改变， 没有及时更新小区的相邻关系； 或者环境的变化、 网络规划 人员的遗漏等， 都会造成邻区信息更新不及时。 而利用 MDT技术可以充分 利用路测 UE的测量信息，对周围无线环境情况进行搜集上报。 图 2为利用 MDT测量实现自动邻区信息上报流程图， 如图 2所示， 现有技术中自动邻 区信息上报具体包括以下步骤：
步骤 201 : 源小区选择合适的 UE进行 ANR测量任务； 对于位于小区 中的所有 UE而言， 并非都适合用于 ANR测量， 需要选用较合适的 UE执 行邻区信息的测量；
步骤 202: 源小区将 ANR配置信息下发给 UE; 这里， ANR配置信息 可以通过广播方式通知给所有 UE, 或仅通知给需要执行路测的 UE。 ANR 配置信息主要是要求 UE进行邻区信息测量并在合适时机上报。
步骤 203 : UE进行 ANR测量并记录测量结果， 可以在小区重选流程 中进行；
步骤 204: UE向目标小区上报 ANR LOG测量上报指示；
步骤 205: 目标小区向 UE发送测量记录获取请求；
步骤 206: UE向目标小区进行 ANR LOG测量结果的上才艮；
步骤 207: 目标小区根据 UE上报的路测结果维护邻区关系。
由于路测终端在网络中移动过程中会在不同的位置对邻区进行记录， 终端会将记录到的服务小区信息和对应的邻区信息上报到网络中任一的 eNB或者无线网络控制器 （ RNC , Radio Network Controller ), 而网络侧需 要将路测终端上报的邻区信息传递给服务小区所在的 eNB/RNC 或是邻区 对应的 eNB/RNC , 才能对终端上报的邻区信息进行处理和维护。 目前的路 测邻区信息的上报， 并没有涉及信息上报的 eNB/RNC选择， 显然， 如果路 测结果所上 >¾的 eNB/RNC不合适， 并不能实现小区相关邻区的有效更新。 发明内容

本发明的基本思想为，通过网络侧向 UE发送路测信令，接收到路测信 令的 UE进行服务小区及其邻区的小区信息的检测，并将检测结果上报至网 络侧， 网络侧再将服务小区的小区信息或该服务小区邻区的小区信息发送 给相应的负责邻区维护的相关网络节点， 由这些网络节点根据服务小区的 小区信息或该服务小区邻区的小区信息进行自身邻区列表的维护。
为使本发明的目的、 技术方案和优点更加清楚明白， 以下举实施例并 参照附图， 对本发明进一步详细说明。
实施例一
图 3为本发明实施例一的邻区列表自动维护方法流程图， 如图 3所示， 本示例的邻区列表自动维护方法具体包括以下步骤：
步骤 301 : UE根据 ANR配置信息进行当前服务小区及其邻区的小区 信息检测， 并记录检测到的当前服务小区及其邻区的小区信息。 比如记录 的服务小区和该服务小区邻区的小区信息包含但不限于以下信息： 小区的 频点信息、 小区的物理标识信息（ LTE小区为物理小区标识（ PCI, Physical Cell Identity ), UTRAN 小区为主同步码 ( PSC , Primary Synchronization Code )、 GSM小区包括基站标识 BSSI信息（其中， BSSI( Base Station Identity ) 是 GSM基站的标识）、 小区的全局标识信息 （LTE 小区为小区全球标识 ( CGI, Cell Global Identity ), UTRAN小区为 ( CI, Cell Identity )、 GSM小 区为 CI )。 其中， 小区的全局标识信息是上报信息中必须携带的信息， 而小 区的频点信息以及小区的物理标识信息是上报信息中可选的携带信息。 月良 务小区邻区为与该服务小区相邻的小区， 可以包含一个或者多个检测到的 小区信息。 需要说明的是， 上述的检测小区信息， 根据实际情况也可能只 检测当前服务小区的邻区的小区信息，如网络侧能获取 UE当前服务小区的 小区信息的情况下。 这里， 网络侧可以通过公共广播消息或专用的配置消息或新设专用消 息承载 ANR配置信息， 并发送给 UE。 公共广播消息为***信息块（SIB, System Information Block ) SIB2或 SIB3； 所述专用的配置消息为无线资源 控制连接重配置消息（ RRCConnection Reconfiguration )、无线资源控制连接 建 立 消 息 ( RRCConnectionSetup ) 或 空 闲 MDT 配 置 消 息 ( IdleMDTConfiguratioii/IdleLoggingConfiguration )。 在下述实施方式中， 网 络侧同样可以以这种方式下发路测信令（ANR配置信息），本发明中不再一 一进行描述。 本领域技术人员应当理解， 上述 ANR配置信息的发送方式仅 是示例性说明， 并非用于限定。
步骤 302: UE将上述记录信息上报给网络侧； UE将所检测到的检测 结果（ UE检测时当前服务小区及其邻区的小区信息）上报给网络侧。这里， 网络侧主要是指具有网络控制功能的网络节点， 例如， 在通用移动通信系 统 UMTS中，具有网络控制功能的网络节点为 RNC; 在长期演进 LTE*** 中， 具有网络控制功能的网络节点为基站 eNB等。 在本发明的下述实施例 中， 网络侧具有相同的含义， 本发明不再——描述。
步骤 303: 网络侧接收到上述记录信息后， 获取记录信息中服务小区的 小区信息，准备将 UE所上报的与该服务小区相关的邻区的小区信息传递给 服务小区所属的网络节点， 在 UMTS网络中， 服务小区所属的网络节点是 RNC, 在 LTE网络中， 服务小区所属的网络节点是 eNB。
步骤 304: 若接收到 UE记录信息的网络节点和记录中服务小区所属的 网络节点之间有直接接口 （如在 UMTS网络中， RNC之间为 Iur接口， 在 LTE网络中， eNB之间是 X2接口）， 则将该服务小区邻区的小区信息通过 该直接接口传递给服务小区所属的网络节点， 否则执行步骤 305。
步骤 305: 接收到 UE记录信息的网络节点通过核心网 （具有网络控制 功能的网络节点的上级节点， 在 LTE中为 MME )将 UE上>¾的记录信息传 递给服务小区所属的网络节点。 在 UMTS 网络中， RNC和 CN之间为 Iu 接口， 在 LTE网络中， eNB和 MME之间是 S1接口。
本领域技术人员应当理解， 上述的步骤 304和 305之间没有执行顺序 的限制。
步骤 306: 服务小区所属的网络节点接收到上述邻区信息后， 进行本地 邻区维护， 优化邻区信息。 比如当该服务小区目前没有配置传递信息中的 邻区， 若接收到多次相同的邻区信息， 则将该邻区添加为该服务小区的邻 区。
实施例二
图 4为本发明实施例二的邻区列表自动维护方法流程图， 如图 4所示， 本示例的邻区列表自动维护方法具体包括以下步骤：
步骤 401 : UE根据 ANR配置信息进行服务小区及其邻区的小区信息 的检测和记录。 记录的服务小区和服务小区邻区的小区信息包含但不限于 以下信息：小区的频点信息、小区的物理标识信息（LTE小区为 PCI、UTRAN 小区为 PSC )、 GSM小区情况下可包含 BSS基站标识 BSSI、 小区的全局标 识信息 （LTE小区为 CGI、 UTRAN小区为 CI、 GSM小区为 CI )。 服务小 区邻区的小区信息可以包含一个或者多个检测到的小区信息。
步骤 402: UE将上述服务小区及其邻区的小区信息上报给网络侧。 步骤 403: 网络侧接收到上述服务小区及其邻区的小区信息后， 获取服 务小区的小区信息和对应的服务小区邻区的小区信息， 准备将该服务小区 的小区信息传递给所上报的服务小区的各邻区所属的网络节点， 在 UMTS 网络中， 各邻区所属的网络节点是 RNC, 在 LTE网络中， 各邻区所属的网 络节点是 eNB。
步骤 404: 若接收到 UE上报的服务小区及其邻区的小区信息的网络节 点 （网络侧）和所上报的服务小区的各邻区所属的网络节点之间有直接接 口 （在 UMTS网络中， RNC之间为 Iur接口， 在 LTE网络中， eNB之间是 X2接口 ), 则将服务小区的小区信息通过该直接接口发送给所上报的服务 小区的各邻区所属的网络节点， 否则执行骤 405。
步骤 405: 接收到 UE记录信息的网络节点通过核心网将服务小区的小 区信息传递给所上报的服务小区的各邻区所属的网络节点。 在 UMTS网络 中， RNC和 CN之间为 Iu接口， 在 LTE网络中， eNB和 MME之间是 S1 接口。
本领域技术人员应当理解， 上述的步骤 404和 405之间没有执行顺序 的限制。
步骤 406: 邻区所属的网络节点接收到上述邻区的小区信息后， 进行本 地邻区维护， 优化邻区信息。 比如当该邻区未将上述月良务小区作为邻区时， 若接收到多次相同的服务小区的小区信息， 则将该服务小区添加为邻区。
本实施例与实施例一比较类似， 最大的区别在于， 网络侧接收到 UE 上报的服务小区及其邻区的小区信息后， 是将服务小区的小区信息分别发 送给所检测出的服务小区的各邻区所属的网络节点。 而上一实施例则是将 服务小区邻区的小区信息发送给服务小区所属的网络节点。
