Description

一种管理小区间邻接关系的方法及装置 技术领域
本发明涉及移动通信系统的邻接关系管理技术， 尤其涉及一种管理 d、 区间邻接关系的方法及装置。 背景技术
在移动通信网络中， 一般釆用分层管理的方式对各网元（NE, Network Element )设备进行管理。具体地，移动通信网络中包含网络管理系统（ NMS , Network Management System )和网元管理系统 ( EMS , Element Management System )等不同层次的管理系统， 其中， EMS主要完成网元管理层（ EML, Element Management Layer )功能， 管理一个或多个来自于同一个设备供应 商的、 不同类型网络的 NE; NMS 主要完成网络管理层 （NML, Element Management Layer )功能， 负责一个被管网络内所有 NE的管理； 实际应用 中， NMS通过自身和 EMS之间的北向接口 （ Itf-N )与 EMS进行通信， 以 达到管理不同厂商的设备及其相关功能的目的。
在移动通信网络中， 对用户而言最直观的服务对象提供者是 UE, UE 直接与 NE交互， 为用户提供通话、 数据处理等各种服务。 通常， 每个 NE 管辖多个小区， 各小区为 UE提供服务， 每个小区的覆盖范围有限， UE的 工作密切依赖于其所处的小区。 一般， 在移动过程中， UE需要根据当前服 务小区的邻接小区的配置情况， 选择切换时机以及切换的目的小区。 其中， 切换的目的小区与当前服务小区， 可能由同一个 NE 管辖， 也可能由不同 NE管辖， 甚至还可能由不同移动通信系统管理， 如果移动通信系统中各小 区的邻接小区配置不合适、遗漏甚至错误，就可能导致 UE的服务质量降低 甚至业务中断， 因此， 邻接小区的配置和优化对于网络维护来说很重要。 目前在 UMTS 陆地无线接入网 （UTRAN , UMTS Terrestrial Radio Access Network ) 网络中， 网络初始建立时， 根据规划情况， 通过人工配置 方式在 EMS上配置小区及其邻接小区列表， 下发到 NE; 网络运行过程中， 定期釆集和分析网络运行数据， 在 EMS层通过人工方式调整小区的邻接小 区配置， 并通知 NE更新其所辖小区的邻接小区配置， 并且在维护过程， 由 管理人员根据切换相关的指标并结合数据配置的情况， 判断邻接小区的配 置是否正确。
上述配置邻接小区列表的方法， NE不具备管理自身小区邻接关系的能 力， 不能够根据当前小区的配置信息， 来实时更新或生成适合当前的邻接 小区列表， 从而不能保证所述邻接列表的正确性； 并且， NE之间的邻接关 系、 以及跨 EMS的邻接关系管理均需要 NE之间协商或 EMS之间协商才 能实现， 这会大大增加链路和交互的消息数量， 从而增加移动通信系统的 通信负载； 并且， 上述的配置方法， 需要在釆集到全网的性能测量数据、 配置数据之后， 才能进行人工分析比对， 得到优化调整结果， 耗时长， 且 不能及时根据小区配置信息的变更， 更新和调整邻接关系。 发明内容

本发明的基本思想是： 在 UTRAN网络中， 由 NMS、 EMS和 NE三层 协作配合， 实现移动通信系统中小区的邻接关系的自动管理。
本发明的一种管理小区间邻接关系的方法， 可以应用于 UTRAN 网络 中， 参照图 1所示， 主要包括以下步骤：
步骤 101 : 实时获取当前小区的邻区配置信息； 具体地， 可以通过 NE, 或者在 NE中设置能够用于获取所述相邻小区 配置信息的设备， 来实现该获取过程。
所获取到的邻区配置信息可以包括邻接小区的 ID、 所属 NE的标识、 网络型号等能够用于唯一标识该邻接小区的信息， 或者能够用于定位所述 相邻小区的定位信息。
其中， NE可以通过自身下属小区内的 UE来获取小区的邻区配置信息。 具体地， 釆集的具体方式由 NE决定， NE实时检测自身所辖区域内是否有 UE能够满足预先设定的检测条件， 如果有， 则向满足所述检测条件的 UE 中的任意一个或多个下发测量任务， 请求 UE检测指定小区的邻区配置信 息， UE检测到所述小区的邻区配置信息后上报给所述 NE; 否则， NE不下 发所述测量任务。 其中， 指定小区的邻区可以包含当前 NE辖区内的邻区、 当前 EMS辖区内的邻区、 以及跨 EMS区域内的邻区。
其中， 预先设定的检测条件， 具体可以是预先设定的检测阔值， 如果 UE当前的流量低于所设定的检测阔值， 则所述 UE满足所述检测条件， 否 则， 所述 UE不满足所述检测条件。 其中， 还可以预先设置一个所选取 UE 的数量上限， NE选取用于执行测量的 UE时， 所选取 UE的数目不超过该 上限值。
步骤 102: 根据预先配置或缺省配置的、 用于指定 NMS、 EMS和 NE 的邻接关系列表配置能力的分层控制策略表， NMS、 EMS, NE依次对所述 邻区配置信息进行分析处理， 调整所述小区的邻接关系列表。
这里， 所述分层控制策略表， 用于指定 NMS、 EMS和 NE的邻接关系 列表配置能力， 包含有 NE辖区邻接关系列表配置策略、 EMS辖区邻接关 系列表配置策略以及跨 EMS 区域邻接关系列表配置策略， 分别用于指定 NMS、 EMS以及 NE在 NE辖区的、 EMS辖区的、 以及跨 EMS区域的邻 接关系列表配置能力。 通常 NMS、 EMS, NE能够支持的邻接关系列表配置能力如下表 1所 示， 实际应用中， 分层控制策略表也可遵循缺省配置。
Figure imgf000009_0001
表 1
其中，分层控制策略可以通过静态配置的方式配置到 NMS和 /或 EMS, 由 EMS下发给 NE, 并在 NMS、 EMS和 NE上分别保存。 具体地， 如果是 配置到 NMS ,则由 NMS下发到 EMS , EMS再下发到 NE,并在 NMS、 EMS 和 NE上分别保存； 如果是配置到 EMS , EMS将所述分层控制策略上报给 NMS, 并下发到 NE, 在 NMS、 EMS和 NE上分别保存； 如果同时在 NMS 和 EMS配置并保存， 则可以由 EMS下发到 NE, NE再将分层控制策略保 存。
这里，在 NMS、 EMS以及 NE上保存的分层控制策略可以不同，例如， 依据 NMS、 EMS和 NE对移动通信系统的管理范围， 可以在 NMS上保存 NE辖区邻接关系列表配置策略、 EMS 辖区邻接关系列表配置策略以及跨 EMS区域邻接关系列表配置策略，在 EMS上保存 NE辖区邻接关系列表配 置策略、 EMS辖区邻接关系列表配置策略， NE上只需要保存 NE辖区邻接 关系列表配置策略。
其中， 分层控制策略的变更可以通过静态配置方式实现， 还可以根据 NE或 EMS上报的信息， 实时修改。 具体地，修改分层控制策略的过程如下： 如果 NE当前支持的邻接关系 列表配置能力变更， 例如， NE由原来的支持变更为不支持、 或由原来的不 支持变更为支持， 首先， NE更新自身保存的分层控制策略并上报给 EMS, 或者只向所述 EMS上报自身的变更信息； EMS根据 NE上报的分层控制策 略或变更信息， 更新自身所保存的分层控制策略， 即将自身所保存分层控 制策略中所述 NE的策略进行变更（例如将对应 NE的支持变更为不支持或 将不支持变更为支持）， 并且， EMS 将更新后得到的分层控制策略或所述 NE的变更信息上报给 NMS, NMS根据 EMS上报的分层控制策略或所述 NE的变更信息， 更新自身保存的分层控制策略， 具体更新过程与 EMS更 新分层控制策略的过程相似。
具体地， 如果配置有邻接关系管理参数， 则步骤 102 中对所获取的邻 区配置信息进行分析处理， 调整所述小区的邻接关系列表， 可以包括： 所 述 NE获取到所述邻区配置信息后，按照所述分层控制策略表、以及预先配 置的邻接关系管理参数， 所述 NE、 EMS, NMS依次对所述邻区配置信息 进行分析处理， 调整所述小区的邻接关系列表。
这里， 所述邻接关系管理参数用于表示邻接关系配置的管理条件， 例 如， 邻接关系管理参数可以包含用于表示不允许切换到指定小区的参数、 和 /或用于表示指定邻接关系不能被删除的参数等。 这里， 邻接关系管理参 数的配置为可选， 具体可以根据实际应用的需要确定是否配置。
例如， 所配置的邻接关系管理参数具体可以包含禁止切换到指定小区 的列表、 不允许删除指定邻接关系的列表、 新增邻接信息的条件阔值、 删 除邻接信息的条件阔值。 其中， 禁止切换到指定小区的列表可以包含不允 许切换到的指定小区的相关信息， 不允许删除指定邻接关系的列表可以包 含禁止删除的指定邻接信息， 以避免合理规划的邻接信息在暂时无业务时 被误删除。 新增邻接信息的条件阔值可针对 NE和 EMS设置不同的阔值， 例如， 新增邻接信息的条件阔值可以为一定时间周期内 UE检测上报的某一小区 次数是否超过特定频度。
邻接关系删除的条件阔值可针对 NE和 EMS设置不同的阔值。 例如， NE上邻接关系删除的条件阔值可以为一定时间周期内 UE检测上报的某小 区的邻接小区的次数低于 0; EMS上邻接关系删除的条件阔值可以为一定 时间周期内某个邻接关系切换次数低于设定的阔值。
具体地， 配置邻接关系管理参数的方式， 与上述配置分层控制策略表 的方式相同。 这里， 可以通过静态配置的方式将邻接关系管理参数配置到 NMS或 EMS,再由 EMS将邻接关系管理参数下发到 NE,并在 NMS、EMS、 NE上分别保存所述邻接关系管理参数。
这里， 每层所保存的邻接关系管理参数可以根据其保存的分层控制策 略， 进行增减。 例如， 对于 NE来说， NE只能够支持 NE辖区邻接关系列 表的配置， 则在 NE上只需要保存 NE辖区分层控制策略、 以及 NE辖区相 关的邻接关系管理参数。
具体地， 所述 NE、 EMS , NMS依次对所述邻区配置信息进行分析处 理， 调整所述小区的邻接关系列表， 包括： 如果配置有所述邻接关系管理 参数， 所述 NE、 EMS, NMS依次按照配置到自身的分层控制策略、 以及 邻接关系管理参数， 对所述邻区配置信息进行分析处理， 确定所述小区在 NE辖区内的邻区、 和 /或在 EMS辖区内的邻区、 和 /或在跨 EMS区域内的 邻区， 并调整各自所保存邻接关系列表中所述小区的 NE辖区邻接信息、和 /或 EMS辖区邻接信息、 和 /或跨 EMS区域邻接信息；
如果没有配置所述邻接关系管理参数， 所述 NE、 EMS, NMS依次按 照配置在自身的分层控制策略， 对所述邻区配置信息进行分析处理， 确定 所述小区在 NE辖区内的邻区、和 /或在 EMS辖区内的邻区、和 /或在跨 EMS 区域内的邻区，并调整各自所保存邻接关系列表中所述小区的 NE辖区邻接 信息、 和 /或 EMS辖区邻接信息、 和 /或跨 EMS区域邻接信息。
这里， 所述 NE才艮据所获取到的邻区配置信息， 确定所述小区的 NE辖 区邻接小区的方法，可以按照多个 UE检测上报的所述小区的频次统计、或 分析 UE上报的测量报告来实现，具体方法可以通过相关技术实现，在此不 再赘述。 EMS和 NMS也可以通过相关技术实现所述小区的 NE辖区、 EMS 辖区或跨 EMS区域邻接小区的确定。
这里， 调整所述邻接关系列表中所述小区的 NE辖区邻接信息、 和 /或 EMS辖区邻接信息、 和 /或跨 EMS区域邻接信息， 可以按照以下步骤进行： 检测所述小区的邻接关系列表中，是否已配置有所述小区与所确定 NE辖区 和 /或 EMS辖区和 /或跨 EMS区域的邻接小区之间的邻接信息， 如果是， 则 不需要调整所述 NE的邻接关系列表；否则，在所述小区的邻接关系列表中， 新增、 删除或修改所述小区与所确定 NE辖区内、 和 /或 EMS辖区内、 和 / 或跨 EMS区域内部区之间的邻接信息。
这里， 如果预先配置有邻接关系管理参数， 则在所述小区的邻接关系 列表中，新增、删除或修改所述小区与所确定 NE辖区邻接小区之间的邻接 信息， 具体还可以是： 判断要调整的邻接信息， 是否能够满足预先配置的 邻接关系管理参数的要求， 如果是， 则在所述邻接关系列表中， 新增、 删 除或修改所述邻接信息； 否则， 不进行所述邻接信息的新增、 删除或修改。
这里， 如果所述小区的邻接关系列表当前已配满， 新增所述邻接信息 时， 可以按照预先设定的邻接信息调整算法， 结合预先配置的邻接关系管 理参数， 删除所述邻接关系列表中的部分邻接信息后， 再将要新增的邻接 信息添加到所述邻接关系列表中。 其中， 所述邻接信息调整算法也可以根 据由 NE或 EMS或 NMS来决定。
其中， 在 EMS进行邻接关系列表的调整过程中， 同时还记录邻接关系 处理的日志， 便于查询。
这里， 若上一级的邻接关系调整与下级的调整出现冲突， 在满足邻接 小区管理参数的前提下， 以最后更新得到的邻接关系列表为准。
其中，在所述 NMS完成所述邻接关系列表的调整后，所述方法还包括： 所述 NMS 将自身调整得到的邻接关系列表下发到 EMS , EMS 再将所述 NMS下发的邻接关系列表下发到 NE, 要求配置生效； NE接收到所述邻区 关系列表后， 将最终生效的邻区关系列表上传到 EMS, EMS再将所述最终 生效的邻区关系列表上传给 NMS。
这样， 按照上述的方法， 由 NE、 EMS , NMS分工合作， 能够完成整 个移动网络中所有小区之间邻接关系的自动发现和调整。
为实现上述方法， 本发明还提供了一种管理小区间邻接关系的装置， 所述装置包括： 获取单元、 一个或多个调整单元， 其中， 获取单元， 用于 实时获取当前小区的邻区配置信息； 调整单元， 用于根据预先配置或缺省 配置的、 用于指定 NMS、 EMS和 NE的邻接关系列表配置能力的分层控制 策略表， 对所述获取单元获取到的邻区配置信息进行分析处理， 调整所述 小区的邻接关系列表。
其中， 所述获取单元部署在网元上； 所述一个或多个调整单元， 分别 部署在 NMS、 EMS和 NE上。
具体地， 可以根据预先配置的分层控制策略， 在 NMS、 EMS和 NE上 分别部署所述调整单元， 实际应用中， 所述调整单元可以用于： 在配置有 所述邻接关系管理参数时， 按照所述分层控制策略表和预先配置的邻接关 系管理参数， 对所述邻区配置信息进行分析处理， 调整所述小区的邻接关 系列表； 在没有配置所述邻接关系管理参数时， 按照所述分层控制策略表， 对所述邻区配置信息进行分析处理， 调整所述小区的邻接关系列表。
其中， 部署在所述 NMS上的调整单元， 还用于： 完成所述邻接关系列 表的调整后，将自身调整得到的邻接关系列表下发到 EMS ,使得 EMS将所 述邻接关系列表下发到 NE上， 要求配置生效； NE上的调整单元还用于， 接收到所述 NMS上调整单元下发的邻接关系列表后，将最终生效的邻接关 系列表上传给 EMS ,使得 EMS将所述最终生效的邻接关系列表上传给所述 NMS。
例如，图 2所示的移动通信网络， 包含 NMS— 1、 EMS— 1、 EMS— 2、 NE— 1 和 NE— 2,其中， NMS— 1管理 EMS— 1、 EMS— 2, EMS— 1管理 NE— 1和 NE— 2, 可以在 NMS— 1、 EMS— 1、 EMS— 2、 NE— 1和 NE— 2中的任何一个或多个上 部署对应的调整单元， 在 NE— 1 和 NE— 2 中部署上述的获取单元， 其中， NMS— 1、 EMS— 1、 EMS— 2、 NE— 1和 NE— 2上都保存有邻接关系管理参数。
