Description

小区物理地址的分配方法和基站 技术领域 本发明涉及通信领域, 具体而言, 涉及一种小区物理地址的分配方法和 基站。 背景技术 随着移动通信技术的发展, 在长期演进(Long Term Evolution, 筒称为 LTE ) 系统中, 演进基站 (E-UTRAN Node B , 筒称为 eNB ) 的数量会比较 多, 如果采用传统的人工方法对 eNB进行安装、 配置及维护, 则会耗费大量 的人力、 物力和财力。 为了降低系统的运维成本, 产生了 自组织网络 ( Self Organizing
Network, 筒称为 SON ) 的概念。 它是一种能够对 eNB进行自动安装、 配置 及维护的移动通信网络,相对于以往人工维护的方式, SON可以减少工作量, 进而降氏运营商的运营维护成本。 对于 SON而言, 小区物理地址( Physical Cell Id, 筒称为 PCI ) 的自动 配置是其重要内容之一。 PCI是无线小区的基本配置参数, 当一个新的 eNB 力口入网络中时, 需要为该 eNB支持的所有小区各分配一个 PCI, 从而避免邻 接小区间发生干扰。 传统上, PCI是由网络规划进行分配的, 这也是基站初始配置的工作之 一。 PCI的分配要尽量保证在一定覆盖区域内小区间的物理地址不发生冲突, 保证地理位置上邻近的小区间不发生干 4尤。 目前, 自动配置 PCI的方法主要 有两种: 集中式和分布式。 其中, 集中式方法是由操作和维护功能实体 ( Operations And Maintenance, 筒称为 OAM )通 P eNB一个特定的 PCI值 , eNB将该特定的 PCI值作为新小区的 PCI; 分布式方法是 OAM通知 eNB— 个 PCI的可用值的列表, eNB从这个列表中除掉 PCI限制集合之后, 在剩余 的 PCI值列表中随机选择一个值作为新小区的 PCI。 其中, eNB的 PCI限制 集合包括以下的 PCI: UE向 eNB上 4艮的 PCI; eNB的邻接 eNB通过 X2接 口向 eNB上 4艮的 PCI; 通过其它实现方法得到的 PCI, 例如 eNB 自动监测得 到的 PCI。一般来说,限制集合中的 PCI为新小区的周围小区已经使用的 PCI。 但是 , 由于 LTE系统中只有 504个 PCI , 而 LTE系统中往往 eNB的数 量又会比较多, 按照上述分布式方法对 PCI值进行分配时, 可能会出现 eNB 没有可选择的 PCI值的情况, 例如, OAM 出于各种原因给出的列表中可用 PCI值较少, 而邻接 eNB又通过 X2接口上报了非常多的 PCI限制值的情况 下, eNB可能无法得到符合要求的 PCI。
发明内容 考虑到相关技术中存在的在采用分布式方法进行 PCI 分配时, 基站不能 为其支持的小区选择 PCI的问题而提出本发明, 为此, 本发明的主要目的在于 提供一种在基站间传递中心频点信息的方法, 同时提供这一种使用传递方法的 小区物理地址的分配方法及基站, 以解决上述问题。 为了实现上述目的 ,根据本发明的一个方面 ,提供了一种在基站间传递中 心频点信息的方法。 根据本发明的在基站间传递中心频点信息的方法包括:源基站和目标基站 通过 X2接口消息来相互传递所辖服务小区的邻接小区的中心频点信息 , 服务 小区的邻接小区中心频点信息用于小区物理地址的选择。 为了实现上述目的 ,根据本发明的一个方面,还提供一种小区物理地址的 分配方法, 该方法用于目标基站对归属于目标基站的目标小区分配小区物理地 址。 才艮据本发明的小区物理地址的分配方法包括:目标基站获取操作和维护功 能实体发送的可用小区物理地址列表, 并将可用小区物理地址列表中除去目标 小区的限制小区物理地址得到可选小区物理地址集合; 目标基站的 X2接口消 息中包含服务小区的邻接小区的中心频点信息; 目标基站通过 X2接口消息获 取服务小区的邻接小区的中心频点信息, 以预定方式获取第一参考小区物理地 址集合, 其中, 第一参考小区物理地址集合中的小区中心频点信息与目标基站 的目标小区的中心频点信息不同; 目标基站将可用小区物理地址列表与第一参 考小区物理地址集合的交集形成第二参考小区物理地址集合; 目标基站在可选 'J、区物理地址集合中随机选择一个物理地址作为目标小区的小区物理地址 , 如 果可选小区物理地址集合为空, 则在第二参考小区物理地址集合中随机选择一 个小区物理地址作为目标小区的小区物理地址。 为了实现上述目的, 才艮据本发明的另一个方面, 提供了一种基站。 根据本发明的基站包括: 第一获取模块, 用于获取操作和维护功能实体发 送的小区物理地址列表和目标小区的限制小区物理地址; 第一处理模块, 用于 从可用小区物理地址列表中除去目标小区的限制小区物理地址得到可选小区 物理地址集合; 第二获取模块 , 用于根据通过 X2的接口消息中获取的小区的 中心频点信息, 以预定方式获取第一参考小区物理地址集合, 其中, 第一参考 'J、区物理地址集合中的小区中心频点信息与目标小区的中心频点信息不同; 第 二处理模块 , 用于将第二获取模块获取的物理地址集合与可用小区物理地址集 合取交集形成第二参考小区物理地址集合; 选择模块, 用于为目标小区选择小 区物理地址; 调用模块, 用于调用选择模块, 选择模块在第一处理模块的可选 小区物理地址集合中为目标小区随机选择一个小区物理地址作为目标小区的 小区物理地址 , 并在可用小区物理地址集合为空的情况下 , 在第二处理模块的 第二参考小区物理地址集合中随机选择一个小区物理地址作为目标小区的小 区物理地址。 通过本发明的上述至少一个技术方案 ,通过在分布式方法采用与目标小区 的中心频点信息不同的小区的 PCI作为目标小区的 PCI, 相比于现有技术, 能 够提高对目标小区配置 PCI的成功率, 避免了小区间的 PCI发生冲突及小区间 的干扰。 附图说明 附图用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与本发 明的实施例一起用于解释本发明, 并不构成对本发明的限制。 在附图中: 图 1是才艮据本发明方法实施例的小区物理地址的分配方法的流程图; 图 2 是才艮据本发明方法实施例的小区物理地址的分配方法的详细处理流 程图; 图 3是根据本发明方法实施例的基于 X2接口的消息建立流程图; 图 4是根据本发明方法实施例的基站配置更新的流程图; 图 5是根据本发明装置实施例的基站的结构框图。 具体实施方式 功能相克述 由于目前 LTE系统中的 PCI数量有限, 可以在 PCI 自动配置时考虑 PCI 的复用。 对于 LTE小区, 同频组网情况下, 若邻区同频同 PCI则会造成小区间 严重干 4尤, 导致小区不可用; 异频组网情况下。 可以允许邻区异频同 PCI , 由 于小区的中心频点不一致就不会造成干扰, 不会造成小区间的物理地址冲突。 因此, 可以允许新小区复用其周围异频小区的 PCI , 基于上述思想, 本发明提 出了一种在基站间传递中心频点信息的方法以及使用该方法的一种小区物理 地址的分配方案, 以解决现有技术所存在的问题。 下面将结合附图详细描述本发明。 方法实施例 1 根据本发明实施例 ,提供了一种在基站间传递中心频点信息的方法以及使 用该方法一种小区物理地址的分配方法。 需要说明的是, 为了便于描述, 在下文中以步骤的形式示出并描述了本发 明的方法实施例的技术方案, 在下文中所示出的步骤可以在诸如一组计算机可 执行指令的计算机系统中执行。 虽然在相关的附图中示出了逻辑顺序, 但是在 某些情况下 , 可以以不同于此处的顺序执行所示出或描述的步骤。 在不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互组合。 图 1 是 居本发明实施例的小区物理地址的分配方法的流程图, 如图 1 所示, 目标基站对归属于目标基站的目标小区分配小区物理地址包括以下步骤 (步骤 S 102至步骤 S 108 ): 步骤 S 102 , 目标基站获取操作和维护功能实体发送的可用小区物理地址 列表, 并将可用小区物理地址列表中除去目标小区的限制小区物理地址得到可 选小区物理地址集合; 步骤 S 104 , 目标基站的 X2接口消息中包含服务小区的邻接小区的中心 频点信息, 所述服务小区的邻接小区中心频点信息用于小区物理地址的选择。 其中, X2接口消息包括以下至少之一: X2建立请求消息、 X2建立响应消息、 基站配置更新消息; 目标基站通过 X2接口消息获取服务小区的邻接小区的中 心频点信息, 以预定方式获取第一参考小区物理地址集合, 其中, 第一参考小 区物理地址集合中的小区中心频点信息与目标基站的目标小区的中心频点信 息不同; 步骤 S 106 , 目标基站将可用小区物理地址列表与第一参考小区物理地址 集合的交集形成第二参考小区物理地址集合; 步骤 S108 , 目标基站在可选小区物理地址集合中随机选择一个物理地址 作为目标小区的小区物理地址, 如果可选小区物理地址集合为空, 则在第二参 考小区物理地址集合中随机选择一个小区物理地址作为目标小区的小区物理 地址。 其中,这里的第一参考小区物理地址集合是指与目标小区异频的周围小区 的 PCI集合。 目标基站可以通过下述四种预定方式确定第一参考小区物理地址集合。 方式一: 目标基站通过 X2口收集与目标基站具有 X2连接的所有基站所 支持的小区的小区物理地址和中心频点信息、 以及该所有基站所支持的小区的 相邻小区使用的小区物理地址和中心频点信息; 目标基站将收集的中心频点信 息中与目标小区的中心频点信息不同的中心频点信息对应的一个或多个小区 的小区物理地址确定为第一参考小区物理地址集合。 方式二: 目标基站通过 X2口收集与目标基站具有 X2连接的所有基站所 支持的小区的相邻小区使用的小区物理地址和中心频点信息; 目标基站将收集 的中心频点信息中与目标小区的中心频点信息不同的中心频点信息对应的一 个或多个小区的小区物理地址确定为第一参考小区物理地址集合。 方式三: 目标基站通过 X2口收集与目标基站具有 X2连接的所有基站所 支持的小区的相邻小区使用的小区物理地址和中心频点信息; 目标基站将从收 集的中心频点信息与目标小区的中心频点信息不同的中心频点信息对应的一 个或多个小区的小区物理地址中, 除去由用户设备上 4艮的与目标小区的中心频 点信息不同的所有小区的小区物理地址而得到的一个或多个小区物理地址确 定为第一参考小区物理地址集合。 方式四:目标基站收集用户设备上 4艮的周围小区的小区物理地址和中心频 点信息、 通过 X2 口收集与目标基站具有 X2连接的所有基站所支持的小区的 小区物理地址和中心频点信息、 以及该所有基站所支持的小区的相邻小区使用 的小区物理地址和中心频点信息、 目标基站自身监测到的周围小区的小区物理 地址和中心频点信息; 目标基站将收集的中心频点信息中与目标小区的中心频 点信息不同的中心频点信息对应的一个或多个小区的小区物理地址确定为第 一参考小区物理地址集合。 另外 , 如果可选小区物理地址集合为空, 则目标基站向 OAM发送第一响 应消息, 通知 OAM 目标小区在可选小区物理地址集合中的选择小区物理地址 失败; OAM 获取响应消息后, 判断目标基站是否在第二参考小区物理地址集 合中为目标小区选择小区物理地址, 向目标基站发送判断结果。 如果目标基站在第二参考小区物理地址集合中为目标小区分配小区物理 地址失败的情况下, 则目标基站向 OAM发送第二响应消息, 通知 OAM 目标 小区在第而参考 、区物理地址集合中的选择 'J、区物理地址失败。 通过本发明实施例提供的技术方案 ,通过在分布式方法采用与目标小区的 中心频点信息不同的小区的 PCI作为目标小区的 PCI , 相比于现有技术 , 能够 提高对目标小区配置 PCI的成功率, 避免了小区间的 PCI发生冲突及小区间的 干扰, 从而提高了网络运营性能, 减少网络运维成本。 实例 在系统中新加入一个 eNB, 需要通过自动配置来实现新 eNB下的小区的 物理地址分配, 以便小区开始正常的工作。 图 2是根据本发明的 eNB 自动配置 为其所支持的小区分配 PCI的流程图 , 为了清楚描述, 下面以该 eNB为小区 1 (即上文所述的目标小区)分配 PCI为例对本发明实施例进行说明, 包括以下 处理。 SI , OAM向 eNB发送可用 PCI集合, 例如, OAM按照 PCI的规划原则 及根据运营商的需求为该 e NB下发可用 PCI值的列表。
S2, eNB通过 UE上报、 X2接口上报、 以及基站自身监测等方式获取小 区 1的周围小区已使用的 PCI集合, e NB为了使小区 1不与小区 1的周围小 区使用相同的 PCI,将小区 1的周围小区已使用的 PCI集合作为 PCI限制集合, eNB在可用 PCI集合中剔除 PCI限制集合后得到 PCI可选集合(即, 上文所述 的可选小区物理地址集合 ) (对应于上述的步骤 S102 ), 即该 PCI可选集合中的 PCI是可以给小区 1选用 , 且保证小区 1在 PCI可选集合中选到的 PCI不会与 其周围小区使用的 PCI重复。
S3 , eNB通过 X2接口收集与该 eNB具有 X2连接的所有基站所支持的小 区的 PCI和中心频点信息、 及该所有基站所支持的小区的相邻小区使用的 PCI 和中心频点信息后, eNB在获得的所有小区中, 选择与小区 1的中心频点信息 不同的小区的 PCI,确定与小区 1的中心频点信息不同的小区的 PCI集合(即, 上文所述的第一参考小区物理地址集合)(对应于上述的步骤 S104 ), 并将该 PCI集合与 OAM发送的可用 PCI集合取交集得到 PCI复用集 (即, 上文所述 的第二参考小区物理地址集合)(对应于上述的步骤 S 106 ), 该 PCI复用集合中 的 PCI是可以为小区 1选用的 ,且小区 1在 PCI复用集合中选择的 PCI值会与 小区 1周围的异频小区的 PCI值重复。 为了得到与该 eNB具有 X2连接的所有基站所支持的小区的相邻小区使 用的中心频点信息 , 在 X2的接口消息中除了传递服务 、区的邻接小区的 PCI 之外还需要传递服务小区的邻接小区的中心频点信息。 见图 3 X2建立消息流 程中的 X2建立请求消息、 X2建立响应消息和图 4 ENB配置更新流程的 ENB 配置更新消息 , 在这三条消息中扩展服务小区的邻接小区信息 , 现有邻接小区 信息包含小区的 PCI、 小区的全局 ID, 新增小区的中心频点信息 (EARFCN ( E-UTRA Absolute Radio Frequency Channel Number, 筒称为 EARFCN ), 具 体的信息结构见表 1的服务小区的邻接小区的中心频点信息结构图。 表 1
Figure imgf000009_0001
图 3是根据本发明实施例的基于 X2接口的消息建立流程图 , 如图 3所 示, eNB是新建立的基站, eNB 1为该 eNB的一个相邻基站, eNB向 eNB 1 发送 X2建立请求, 口果 eNB 1中包括三个小区 a、 b、 c , 且小区 a的相邻小 区为 d, 小区 b的相邻小区为 e , 小区 c无相邻小区, 则 e NB 1会^)夺小区 a、 b、 c、 d、 e的 PCI和中心频点信息通过 X2建立响应发送给 eNB。 叚设 { a、 b、 c、 d、 e }的 PCI集合为 { 0、 P、 Q、 R、 S } , 且小区 c、 d、 e与小区 1是 异频的。 那末 PCI集合 {Q、 R、 S }就是上文所述的第一参考小区物理地址集 合, eNB将 PCI集合 {Q、 R、 S }与 OAM发送的可用 PCI集合取交集, 叚设 得到的交集是 { Q、 S } , 那末 PCI复用集 (即, 上文所述的第二参考小区物 理地址集合 ) 就为 { Q、 S }。
54 , e NB首先在 PCI可选集合中为小区 1选择 PCI值, 即在 PCI可选 集合中进行随机选择的一个 PCI值作为小区 1的 PCI , 如果在 PCI可选集合 中随机选择 PCI成功, 则将随机选择到的 PCI值配置为小区 1的 PCI , 并转 入到 S6; 如果在 PCI可选集合中随机选择 PCI值失败, 贝' J转入到 S5。
55 , e NB在 PCI复用集合中为小区 1选择 PCI值 (对应于上述的步骤 S 108 ), 即在 PCI复用集合中进行随机选择的一个 PCI值作为小区 1的 PCI , 将该 PCI值配置为小区 1的 PCI , 并转入到步骤 6。
56 , e NB ^)夺小区 1的 PCI值通 P给 OAM。 下面对本发明实施例的各优选方案进行说明。 优选方案一, 在上述 S3中, e NB通过 X2接口只收集与该 e NB具有 X2 连接的所有基站所支持的小区的相邻小区使用的 PCI和中心频点信息后 , e NB 在获得的所有小区中, 选择与小区 1的中心频点信息不同的小区的 PCI , 确定 与小区 1的中心频点信息不同的小区的 PCI集合(即, 上文所述的第一参考小 区物理地址集合), 并将该 PCI集合与 OAM发送的可用 PCI集合取交集得到 PCI复用集。 这样, 在该复用集中, 不存在与 e NB具有 X2连接的所有基站所 支持的小区的 PCI , 这样 , 可以降低发生 PCI混淆的概率。 优选方案二: 在上述优选方案一的基础上, 为了降低由于小区 1分配的
PCI与异频邻区使用的 PCI重复而导致小区间 PCI混淆的概率 , 需要进一步 保证有可能成为邻区的异频小区不复用同一个 PCI , 这样本发明中的 PCI复 用集可以按照下述方法生成: e NB获取到通过 X2接口上 4艮的所有邻接基站 的小区的与待分配 PCI的小区 1异频的邻接小区的 PCI集合, 再剔除由 UE 上报和其它方法得到的与当前待分配 PCI的小区 1异频的所有小区的 PCI , 得到一个 PCI 集合 (即, 上文所述的第一参考小区物理地址集合), 然后将 此 PCI集合与 OAM发送的可用 PCI集合取交集, 得到 PCI复用集。 这样, PCI复用集合中的 PCI是可以给小区 1选用的且小区 2在 PCI复用集合中选 到的 PCI值会与周围异频小区的 PCI值重复,但是与周围异频邻接小区的 PCI 值重复的概率会大大降低, 从而减小了小区间 PCI值混淆的概率。 优选方案三, 在上述 S3中, 为了增大小区 1的 PCI选择的成功率, 将 有可能成为邻区的异频小区也可以复用同一个 PCI, eNB收集的限制集合中 与当前待分配 PCI的小区 1异频的所有小区的 PCI集合(即, 上文所述的第 一参考小区物理地址集合 ),然后将此 PCI集合与 OAM给出的可用 PCI集合 的取交集, 这样就生成了复用范围更大的 PCI复用集。 另外, 在 S4中, 若在 PCI可选集合中分配 PCI失败, 可以增加 e NB与 OAM的消息交互,基站给 OAM发消息通知小区 1的 PCI选择失败,然后 O AM 给基站发消息通知基站是否进行 PCI复用, 在 S5中, 若在 PCI复用集中分配 PCI失败, 可以增力口 e NB与 OAM的消息交互, 用于 e NB通知 OAM小区 1 复用 PCI失败。 装置实施例 才艮据本发明实施例, 提供一种基站。 图 5示出了根据本发明实施例的基站的结构框图, 如图 5所示, 该基站 包括第一获取模块 10、 第一处理模块 20、 第一获取模块 20、 第二处理模块 40、 选择模块 50和调用模块 60, 下面对上述结构进行描述。 第一获取模块 10,用于获取 OAM发送的小区物理地址列表和目标小区 的限制小区物理地址; 第一处理模块 20, 连接至第一获取模块 10, 用于从 小区物理地址列表中除去目标小区的限制小区物理地址得到可用小区物理地 址集合; 第二获取模块 20 , 用于根据通过 X2的接口消息中获取的小区的中 心频点信息, 以预定方式确定第一参考小区物理地址集合, 其中, 第一参考 'J、区物理地址集合中的小区中心频点信息与目标小区的中心频点信息不同; 第二处理模块 40 , 连接至第一获取模块 10和第二获取模块 20 , 用于将小区 物理地址列表与第一参考小区物理地址集合的交集确定为第二参考小区物理 地址集合; 选择模块 50, 连接至第一处理模块 20和第二处理模块 40, 用于 为目标小区选择小区物理地址; 调用模块 60 , 连接至选择模块 50 , 用于调 用选择模块 50,选择模块 50在第一处理模块 20的可用小区物理地址集合中 为目标小区选择一个小区物理地址作为目标小区的小区物理地址, 并在可用 小区物理地址集合为空的情况下, 在第二处理模块 40 的第二参考小区物理 地址集合中选择一个小区物理地址作为目标小区的小区物理地址。 通过本发明实施例提供的基站,通过在分布式方法采用与目标小区的中心 频点信息不同的小区的 PCI作为目标小区的 PCI, 相比于现有技术, 能够提高 对目标小区配置 PCI的成功率,避免了小区间的 PCI发生冲突及小区间的干扰, 从而提高了网络运营性能 , 减少网络运维成本。 如上所述, 借助于本发明提供的小区物理地址的分配方法和 /或基站, 能 够实现 e NB对本基站小区 PCI的自动配置, 尤其是在 PCI值不够用的情况下 可以通过 PCI复用的方式来为新小区分配 PCI值, 避免 'J、区间的物理地址的冲 突, 避免小区间干扰, 提高了网络密集覆盖区域的 e NB采用分布式方法自动 配置 PCI的成功率, 从而提高了网络运营性能, 减少网络运维成本。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
