在小区建立时, RNC必须知道相应基站的本地小区, 即 RNC 中小区 ID和某基站的本地小区 ID需要有一一对应关系。然而,光纤拉远型基站拥 有几十个拉远单元, 这些拉远单元散布在不同的地域, 同时每个拉远单元 又可能拥有多根天线, 如何在特定的地域的特定天线上建立特定的小区成 为网络规划首先需要解决的问题。 为解决以上问题, 就需要为特定地域拉 远单元的特定天线划分出唯一的本地小区 ID。 目前用于解决上述技术问题的现有技术主要有两种:
现有技术一、 分散管理技术。 即在向移动通信系统中配置新的拉远单 元时(即拉远单元开站时), 为拉远单元设置存储本地小区 ID, 以后拉远单 元一直使用该本地小区 ID进行接入处理。
在使用现有技术一时, 必须保证在拉远单元中事先设置存储本地小区 ID, 并且要确定好某本地小区 ID与拉远单元中具体天线的对应关系。 图 1 为利用现有技术一建立本地小区的流程图。 如图 1 所示, 拉远单元在启动 后可以以固定的本地小区 ID直接接入基站, 由基站分配配套的基带单元, 直接建立本地小区, 并返回本地小区建立成功消息给拉远单元。
对于现有技术一, 存在的主要缺点是在开站时需要给拉远单元写入唯 一的本地小区 ID, 这将给现场工程人员增加工作复杂度, 而且, 同一站点 一般需要三个扇区, 如果将不同的拉远单元的本地小区 ID写反, 则会破坏 既有的无线网络规划。 另外, 这种固定本地小区 ID的方法还有一个缺点是 拉远单元更换或调换不方便, 例如, 将某一地点的拉远单元调换到同一基 站下的另外一个地点, 或者将某一拉远单元调换到另外一个基站下使用, 则必须在安装前更换拉远单元的本地小区 ID, 否则可能出现破坏网络规划 或本地小区 ID冲突等问题。
现有技术二、 集中管理技术。 即将拉远单元的设备 ID作为索引, 在管 理设备的管理数据库中建立实际网络中使用到的所有拉远单元的数据信 息, 拉远单元启动过程中, 从管理设备中动态获得本地小区 ID。 所述的管 理设备为无线子系统的操作维护中心 (OMC-R )或 RNC。
图 2为利用现有技术二建立本地小区的流程图。 在现有技术二中, 拉 远单元不需要事先固定设置存储本地小区 ID, 而是在管理设备的数据库中 设置维护拉远单元的设备 ID与其所辖本地小区 ID的一一对应关系, 在拉 远单元启动后, 向基站发送获取本地小区 ID请求, 其中包括拉远单元的设 备 ID;基站收到请求后,根据所述拉远单元的设备 ID向管理设备获取该拉 远单元对应的本地小区 ID,并将获取的本地小区 ID配置给拉远单元; 拉远 单元以所配置的本地小区 ID直接接入基站, 由基站分配配套的基带单元, 直接建立本地小区, 并返回本地小区建立成功消息给拉远单元。
对于现有技术二, 存在的主要缺点是开站时需要在 OMC-R或 RNC中 录入所有基站所辖所有拉远单元的信息, 建立拉远单元设备 ID与其所辖本 地小区 ID的对应关系, 但拉远单元的设备 ID往往是一串数字, 操作起来 不仅繁瑣, 而且容易出错。 另外, 对于这种集中管理模式, 如果需要更换 或调换拉远单元, 必须更改 OMC-R或 RNC的数据库,增加了设备的维护、 维修成本。 发明内容

图 1为利用现有技术一建立本地小区的流程图;
图 2为利用现有技术二建立本地小区的流程图;
图 3为移动通信系统中的一种网络拓扑结构图;
图 4为本发明所述本地小区拓扑 ID的组成示意图; 图 5为本发明所述拉远单元在初次接入基站时的一种实施流程图; 图 6为本发明所述拉远单元在初次接入基站时的另一种实施流程图; 图 7为本发明所述拉远单元再次接入基站时的一种实施流程图; 图 8为本发明所述本地小区 ID管理装置的结构示意图。 具体实施方式
下面通过具体实施例和附图对本发明做进一步详细说明。
本发明的核心思想为: 在管理设备中按照移动通信系统的网络拓扑结 构设置拉远单元的本地小区拓扑 ID信息, 将本地小区拓扑 ID与本地小区 标识 (即本地小区 ID )绑定以进行管理; 拉远单元通过基站从管理设备中 获取该拉远单元对应的本地小区拓扑 ID。
图 3为移动通信系统中的一种网络拓扑结构图。 参见图 3, NodeBl和 NodeBn为光纤拉远型基站, 拉远单元 RRS1和 RRSn构成星型连接, 拉远 单元 RRSn和 RRSm构成串型连接,图 3所示拉远单元 RRS1和 RRSn分别 对应 NodeBn中的一个光口,而 RRSn和 RRSm仅对应 NodeBn中的一个光 口,且 RRSn和 RRSm分别在 NodeBn同一光口的不同顺序的节点上。所述 管理设备为 RNC或 OMC-R, 基站可以直接与 RNC或 OMC-R通信。
本发明在管理设备上所设置的拉远单元的本地小区拓扑 ID信息基于所 述通信系统的网络拓扑结构。 图 4为本发明所述本地小区拓扑 ID的组成示 意图。 参见图 4, 拉远单元的本地小区拓扑 ID包括六部分字段, 其中, 各 字段所包含的信息如下:
Fl: RNC ID。
F2: NodeB ID。
F3: 光口 ID。
F4: 某一光口上拉远单元的顺序号。
F5: 拉远单元的天线 ID。 F6: 本地小区 ID。
由于 F1至 F4在整个网络中是唯一的, 所以, 通过拓扑 ID就可以唯一 地找到一台拉远单元, 并且通过 F5字段的区分, 可以在一个拉远单元中建 立起多个本地小区。 在具体应用中, 有可能一个天线 ID对应一个本地小区 ID, 也有可能一个以上天线 ID对应一个本地小区 ID。 通过上述六个字段 就可以将本地小区拓扑 ID与本地小区 ID绑定, 从而保证一个具体基站中 的一个具体的本地小区 ID在整个网络中对应一个本地小区拓扑 ID,而本地 小区拓扑 ID在整个网络中是唯一性的, 因此釆用这种绑定关系可以方便对 本地小区 ID的管理。
在管理设备中根据网络拓扑结构设置了本地小区的拓扑 ID后, 就可以 在 RAN中唯一确定一个拉远单元的本地小区。
在管理设备上设置了本地小区的拓扑 ID后, 拉远单元就可以通过基站 获取该拉远单元对应的本地小区拓扑 ID, 并利用所获取的本地小区拓扑 ID 接入基站。
对于一台刚出厂的拉远单元, 其内部仅仅包含设备 ID, 没有被网络赋 予的拓扑 ID, 此时该拉远单元需要使用一个缺省的拓扑 ID发起接入申请。
图 5 为本发明所述拉远单元在初次接入基站时的一种实施流程图。 参 见图 5, 该流程包括:
步骤 501、 拉远单元启动。
步骤 502、 拉远单元发送获取本地小区拓扑 ID请求给基站, 该请求中 至少包括: 所述拉远单元所对应的光口 ID、 该拉远单元在所述光口上的顺 序号、 以及本地小区对应的天线 ID。
步骤 503、基站向管理设备发送查询请求, 该查询请求中包括所述获取 本地小区拓扑 ID请求的内容、 本基站 ID、 以及本基站所属 RNC的 ID。
步骤 504、 管理设备根据所述获取本地小区拓扑 ID请求的内容、 所述 基站 ID和 RNC ID从所设置的本地小区拓扑 ID信息中查询对应的本地小 区拓扑 ID;
步骤 505、 管理设备将查询到的本地小区拓扑 ID返回给基站。
步骤 506、 基站为拉远单元配置所查询到的本地小区拓扑 ID, 将该本 地小区拓扑 ID返回给所述拉远单元。
步骤 507、 拉远单元按获取的拓扑 ID发起接入请求给基站。
步骤 508、基站为拉远单元的本地小区分配配套的基带单元, 建立本地 小区。
步骤 509、 基站返回本地小区建立成功消息给拉远单元。
图 6为本发明所述拉远单元在初次接入基站时的另一种实施流程图。 如图 6所示, 该流程包括:
步骤 601、 基站发送获取本地小区拓扑 ID请求给管理设备, 该请求中 至少包括: 本基站 ID以及本基站所属 RNC的 ID。
步骤 602、 管理设备收到获取本地小区拓扑 ID请求后, 从所设置的本 地小区拓扑 ID信息中查询该请求中所述的基站 ID和 RNC ID对应的所有 本地小区拓扑 ID。
步骤 603、 管理设备将查询到的本地小区拓扑 ID返回给基站。
步骤 604、 基站存储所收到的本地小区拓扑 ID。
步骤 605、 拉远单元启动。
步骤 606、 拉远单元发送获取本地小区拓扑 ID请求给基站, 该请求中 至少包括: 所述拉远单元所对应的光口 ID、 该拉远单元在所述光口上的顺 序号、 以及本地小区对应的天线 ID;
步骤 607、 基站收到所述获取本地小区拓扑 ID请求后, 从所存储的本 地小区拓扑 ID中查询该请求中所述拉远单元所对应的光口 ID、该拉远单元 在所述光口上的顺序号、 以及本地小区对应的天线 ID所对应的本地小区拓 扑 ID。
步骤 608、 基站为拉远单元配置所查询到的本地小区拓扑 ID, 将查询 到的本地小区拓扑 ID返回给拉远单元。
步骤 609、 拉远单元按获取的拓扑 ID发起接入请求给基站。
步骤 610、基站为拉远单元的本地小区分配配套的基带单元, 建立本地 小区。
步骤 611、 基站返回本地小区建立成功消息给拉远单元。
本发明中, 所述拉远单元在获取本地小区拓扑 ID并初次接入基站后, 可以将所获取的本地小区拓扑 ID保存, 当该拉远单元再次接入基站时, 直 接利用所保存的本地小区拓扑 ID向基站发送接入请求。
但是, 所述本地小区拓扑 ID是根据通信系统的网络拓扑结构设置的, 通信系统的网络拓扑结构固定, 则拉远单元所处网络站点的本地小区拓扑 ID也相对应固定, 如果某一站点的拉远单元发生了更换, 而更换后的拉远 单元所保存的本地小区拓扑 ID可能就不是本站点对应的本地小区拓扑 ID, 如果更换后的拉远单元利用其所保存的本地小区拓扑 ID接入基站时, 则会 导致接入错误。 为了防止导致接入错误, 本发明当拉远单元再次接入基站 时釆用了一种特殊的方法。
图 7 为本发明所述拉远单元再次接入基站时的一种实施流程图。 参见 图 7, 该流程包括:
步骤 701、 拉远单元再次启动, 准备接入。
步骤 702、 拉远单元按照所保存的本地小区拓扑 ID向基站发送接入请 求。
步骤 703、 基站向管理设备查询本基站所辖拉远单元的本地小区拓扑
ID。
所述步骤 703可以在步骤 702之后执行, 可以预先执行, 并在步骤 702 后直接执行步骤 704。
步骤 703的具体查询方法可直接按照步骤 601至步骤 604所述方法执 行。 当步骤 703在步骤 702之后执行时, 可以直接按照步骤 601至步骤 604 执行, 也可以对步骤 601至步骤 604进行扩展, 即执行以下步骤 601 '至步 骤 604,:
步骤 601'、 基站发送获取本地小区拓扑 ID请求给管理设备, 该请求中 至少包括: 本基站 ID、 本基站所属 RNC的 ID、 以及步骤 701所述拉远单 元接入的光口 ID和 /或该拉远单元在该光口上的顺序号。
步骤 602'、 管理设备收到获取本地小区拓扑 ID请求后, 从所设置的本 地小区拓扑 ID信息中查询该请求中所述的基站 ID、 RNC ID, 以及光口 ID 和 /或所述顺序号所对应的所有本地小区拓扑 ID。
步骤 603'、 管理设备将查询到的本地小区拓扑 ID返回给基站。
步骤 604'、 基站存储所收到的本地小区拓扑 ID。
步骤 704、 基站判断该接入请求中的本地小区拓扑 ID与发送接入请求 的拉远单元是否匹配, 如果匹配则执行步骤 710, 否则, 执行步骤 705。
步骤 705、基站发送清除指令给发出接入请求的拉远单元, 拉远单元收 到该清除指令后删除所保存的本地小区拓扑 ID。
步骤 706、 拉远单元发送获取本地小区拓扑 ID请求给基站, 该请求中 至少包括: 所述拉远单元所对应的光口 ID、 该拉远单元在所述光口上的顺 序号、 以及本地小区对应的天线 ID。
步骤 707、基站向管理设备发送查询请求, 该查询请求中包括所述获取 本地小区拓扑 ID请求的内容、 本基站 ID、 以及本基站所属 RNC的 ID。
步骤 708、 管理设备根据所述获取本地小区拓扑 ID请求的内容、 所述 基站 ID和 RNC ID从所设置的本地小区拓扑 ID信息中查询对应的本地小 区拓扑 ID; 步骤 709、 管理设备将查询到的本地小区拓扑 ID返回给基站, 基站为 拉远单元配置所查询到的本地小区拓扑 ID。
步骤 710、 基站为拉远单元配置所查询到的本地小区拓扑 ID, 将该本 地小区拓扑 ID返回给所述拉远单元。
步骤 711、 拉远单元按获取的拓扑 ID发起接入请求给基站。
步骤 712、基站为拉远单元的本地小区分配配套的基带单元, 建立本地 小区。
步骤 713、 基站返回本地小区建立成功消息给拉远单元。
从以上流程可以看出, 如果需要更换或调换拉远单元, 则直接由工程 人员更换即可, 不需要在管理站做任何修改。 更换拉远单元后, 拉远单元 自动从网络侧获取拓扑 ID并完成本地小区建立。
如果需要更换拉远单元对应到基站的光口, 则只需要从管理站上将某 一光口的配置数据剪切到另外一个光口即可。
综上所述, 通过 RNC、 NodeB、 光口、 串接顺序号等拓扑参数, 可以 唯一地确定出一个拉远单元, 将本地小区 ID和拓扑结构联合起来, 可以实 现光纤拉远型基站本地小区 ID的便捷管理。
基于上述方法, 本发明还公开了一种移动通信系统中本地小区 ID的管 理装置, 适用于包括管理设备、 基站和拉远单元的移动通信系统。

所述重新请求拓扑 ID单元 806设置在拉远单元上, 用于收到清除指令 后删除所述拉远单元存储模块 804中的本地小区拓扑 ID, 并触发拉远单元 重新发送获取本地小区拓扑 ID的请求给基站。
