Description

一种获取邻接小区信息的方法及系统
技术领域
本发明涉及数字移动通信技术领域， 具体涉及家庭基站通信系统中获取 邻接小区信息的方法及系统。
背景技术
家庭基站（ Home NodeB, 3G系统中简称 HNB; 在长期演进（ Long Term Evolution, LTE ) 系统中称为 Home eNodeB, 简称 HeNB )是一种安装在用 户家里面或者办公区域的小型基站， 网络结构如图 1所示。
其中安全网关（Security Gateway )作用是建立安全的网络通信； 家庭基 站网关（ H(e)NB GW )是为了为了减少对核心网 （ Core Netswork, 简称 CN ) 的影响而引入的， 主要作用是为家庭基站连接和控制服务。 家庭基站网管系 统完成家庭基站的鉴权、 为家庭基站提供各种配置参数等功能。在 LTE家庭 基站系统中， 家庭基站网关也可以不存在， 即家庭基站直接连接到核心网。 切换是移动通信系统中一个重要过程， 以 LTE系统为例， 切换过程的发 起具体包含以下几个步骤：
( 1 )对用户设备（UE )做测量控制配置， 测量控制消息中包含邻接小 区频点， 也有可能包含小区物理小区标识列表；
上述邻接小区频点和物理小区标识列表都是根据基站配置确认。
( 2 ) UE上报测量报告， 包含部接小区的测量结果： 物理小区标识、 信 号质量参数， 还可能包含部接小区的小区全局信息 （根据网络侧的配置） ；
( 3 )基站 (对 3G系统是基站控制器）根据测量报告， 以及本地邻接小 区配置做切换判决， 确定切换的目标小区。
( 4 )根据目标小区和源小区的位置关系以及网络配置直接向目标小区所 在的基站或者核心网触发切换准备过程。
在步骤（1 )中， 基站对 UE的测量控制配置， 只配置测量目标小区的频 点， UE也能够把该频点下小区信息上报。 进一步， 如果基站事先配置好邻 接小区， 在测量控制消息中包含已知的小区的物理小区标识， 可以加快小区 测量速度。
在步骤（2 )中， UE上报小区全局信息， 需要基站做特定测量控制配置， 而且 UE从邻接小区的系统消息中读取邻接小区的小区全局信息耗费时间相 对比较长。 从以上过程分析，为基站配置邻接小区信息可以有效减少 UE测量时间， 提高切换效率。 对于宏基站， 基站的位置及开启时间相对固定， 因此网络规 划完成之后基站的邻接关系已经确定， 可以手动维护邻区配置。 而启用家庭 基站后， 家庭基站是家用设备， 其地理位置和启动时间都是不确定的， 因此 宏基站或家庭基站都无法手动维护邻接家庭基站小区的配置。 对 3G系统存 在同样的问题，而且在 3G系统中，一般情况 UE只上报无线网络控制器 RNC 测量控制中包含的小区， 不会自动扫描， 所以配置邻接小区信息对 3G系统 更重要。

HeNBl : 家庭基站 1 , 管辖家庭基站小区 1 ( Celll ) , 连接到家庭基站 网关 1 ;
HeNB2: 家庭基站 2, 管辖家庭基站小区 2 ( Cell2 ) , 连接到家庭基站 网关 1 ;
HeNB3: 家庭基站 3 , 管辖家庭基站小区 3 ( Cell3 ) , 连接到家庭基站 网关 2;

实施例 1
家庭基站网关或者家庭基站网管系统根据家庭基站上电时的扫描结果为 其他基站 （邻接小区所属基站） 配置邻接小区信息， 具体过程如图 3所示。

步骤 302,家庭基站网关 1或者家庭基站网管系统从家庭基站 HeNBl上 才艮的消息中获取邻接小区信息， 对不同的目标小区， 进行不同的处理过程： 下面对家庭基站网关与家庭基站网管系统的操作分开描述。 对于家庭基站网关， 处理如下：
判断所述邻接小区是否为宏小区， 如果是， 根据邻接小区的小区信息找 到所述宏小区所属的宏基站， 将当前小区的小区信息直接发送给所述宏基站 (步骤 302a ) ; 如果不是， 则说明所述邻接小区为家庭基站小区， 进一步判 断所述邻接小区所属基站是否在所述家庭基站网关管辖下， 如果是， 则所述 家庭基站网关将当前小区的小区信息直接发送给所述邻接小区所属的家庭基 站（步骤 302b ) , 如果不是， 判断所述邻接小区所属基站是否在其他家庭基 站网关管辖下， 如果是， 根据邻接小区的小区信息找到所述邻接小区所属的 家庭基站， 通过所述其他家庭基站网关将当前小区的小区信息发送给所述邻 接小区所属的家庭基站（步骤 302c ) ， 如果不是， 则说明所述邻接小区所属 家庭基站直接连至核心网， 根据邻接小区的小区信息 （如通过小区全局标识 和 /或跟踪区码）找到所述邻接小区所属的家庭基站， 通过预先配置的接口， 将当前小区的小区信息直接发送给所述邻接小区所属家庭基站（步骤 302d )。
具体地：
步骤 302a, 家庭基站网关 1通过邻接小区的 PCI判断所述 Cel 为宏小 区， 根据小区全局标识和 /或跟踪区码找到对应的宏基站 MeNB5 , 通过家庭 基站网关 1和宏基站 MeNB5间的接口 , 向 MeNB5发送邻区配置消息 , 消息 中包含 Celll的小区信息；
家庭基站网关和宏基站间的接口可以通过人工配置或者 SON (自组织网 络）方式。
步骤 302b,家庭基站网关 1判断 Cell2所属基站 HeNB2在家庭基站网关
1管辖下， 即 Cell2所属家庭基站 HeNB2与 Celll所属家庭基站 HeNBl在同 一个家庭基站网关下， 家庭基站网关 1向 Cell2所属的家庭基站 HeNB2发送 邻区配置消息， 消息中包含 Celll的小区信息；
在 LTE家庭基站系统中， 家庭基站网关和家庭基站之间的接口为 S1接 口。
步骤 302c,家庭基站网关 1判断 Cell3所属基站 HeNB3在家庭基站网关 2管辖下， 即 Cell3对应的家庭基站 HeNB3不和 HeNBl在同一个家庭基站 网关下， 家庭基站网关 1根据家庭基站 1上报的邻接小区 Cell3的邻接小区 信息 （如 Cell3的小区全局标识和 /或跟踪区码）找到 Cell3所属的家庭基站 网关 2, 通过家庭基站网关之间的接口向该家庭基站网关 2发送邻区配置消 息， 其中包含 Celll 的小区信息， 家庭基站网关 2收到后， 向 HeNB3发送 Celll的小区信息；
如果家庭基站网关 1预先配置了其它家庭基站网关和跟踪区码的对应关 系， 则家庭基站网关 1可以通过邻接小区所在的跟踪区码找到对应的家庭基 站网关。
在 LTE家庭基站系统中， 家庭基站网关之间的接口可以是 X2接口但不 限于此类型接口。
步骤 302d,家庭基站网关 1判断 Cell4所属家庭基站 HeNB4直接连接到 核心网， 家庭基站网关 1根据 Cell4的邻接小区信息 （比如小区全局标识或 者跟踪区码或者二者的组合 )找到对应的家庭基站 HeNB4, 通过家庭基站网 关和家庭基站 HeNB4 间的接口， 向 HeNB4发送邻区配置消息， 其中包含 Celll的小区信息；
家庭基站网关和直连家庭基站间的接口可以通过人工配置或者自动配置 方式。
对于家庭基站网管系统， 处理如下：
家庭基站网管系统判断 Cell5为宏小区时（例如根据 PCI进行判断 ) , 根据小区信息 （比如小区全局标识或者跟踪区码或者二者的组合）找到对应 的宏基站 MeNB5的网管系统， 通过家庭基站网管系统和宏基站网管系统间 的接口， 把 Celll 的小区信息发送给宏基站网管系统， 宏基站网管系统再向 MeNB5发送邻区配置消息， 其中包含 Celll的小区信息；
家庭基站网关系统判断 Cell2、 Cell3、 Cell4为家庭基站小区， 根据各小 区的小区信息 （比如小区全局标识或者跟踪区码或者二者的组合）找到各个 邻接小区所属基站（HeNB2 、 HeNB3、 HeNB4 ) , 分别向 HeNB2 、 HeNB3 和 HeNB4发送邻区配置消息， 其中包含 Celll的小区信息；
家庭基站网管系统和家庭基站之间的接口釆用 TR069或者其他协议。
步骤 303 目标基站（ HeNB2或者 HeNB3或者 HeNB4或者 MeNB5 )接 收到家庭基站网关或者家庭基站网管系统发送的邻区配置消息， 把 Celll 的 小区信息加到本地保存的邻区列表中。
在加入本地保存的邻区列表之前，还可以先判断邻区列表中是否有 Celll 的小区信息， 没有时， 将其加入邻区列表中。
在本实施例中釆用邻区配置消息向邻小区所属基站发送当前小区的小区 信息， 在其他实施例中也可以使用现有消息携带当前小区的小区信息。 实施例 2
家庭基站根据终端测量结果获取邻接小区信息， 并把邻接小区信息上报 给家庭基站网关或者家庭基站网管系统， 家庭基站网关或者家庭基站网管系 统为其他基站（邻接小区所属基站） 配置邻接小区信息， 具体过程如图 4所 示。
有些情况下， HeNBl扫描不到小区 Cell2但是 UE处于 Celll和 Cell2的 覆盖范围中间时， UE可以检测到小区 Cell2 , 且有可能满足切换要求， 这时 HeNBl和 HeNB2需要互相配置对方管辖的小区为邻接小区。 同理， HeNB3 和 MeNB4存在同样情况。
下面仅以家庭基站网关的处理为例进行说明， 家庭基站网管系统的处理 同家庭基站网关的处理。
步骤 401 , HeNBl为 UE配置测量控制， UE上报邻区测量报告， 其中包 含邻区参数列表， 邻区参数包括 PCI、 小区信息 （条件可选， 包含小区全局 标识、 PLMNID、 跟踪区码）和信号质量等；
上述小区信息条件可选的含义是： 一般情况下 UE上报的测量报告中不 包含小区信息， 因为要获取小区信息需要读取多个系统信息； 如果网络需要 UE上报小区信息， 则需要在测量控制消息的目的中说明。
步骤 402, HeNBl获取步骤 401所述测量报告中的邻区参数列表， 首先 根据 PCI在本地保存的邻区列表中查找， 如果找到对应的小区则不需要新增 邻接小区配置； 如果查找不到， 则增加邻接小区信息， 同时向家庭基站网关 1发送通知消息，其中包含新增的 HeNBl的邻接小区的小区信息（包括 PCI、 小区全局标识、 跟踪区码等参数） ；
可以釆取邻区列表的方式发送所述通知消息。 上述根据 PCI在本地保存的邻区列表中查找的过程，如果存在 PCI冲突， 则需要根据小区全局标识确认具体是哪个小区。 如果 UE发送的测量报告中 不包含小区全局标识，则 HeNBl需要向 UE重新配置测量控制要求读取小区 信息， 或者根据 PCI向家庭基站网关 1或者家庭基站网络管理系统请求该小 区的小区全局标识。 步骤 403 , 家庭基站网关 1接收到家庭基站 HeNBl发送的通知消息， 得 知 HeNBl已更新邻接小区配置， 家庭基站网关 1根据 HeNBl发送的邻接小 区信息确定哪些小区是 HeNBl更新的邻接小区，向 HeNBl 增加的邻接小区 ( Cell2、 Cell3、 Cell4、 Cell5 )对应的基站 HeNB2、 HeNB3、 HeNB4、 MeNB5 发送邻区配置消息， 具体的处理过程参见步骤 302以及图 4的步骤 402a、 402b, 402c和 402d, 此处不再赘述； 步骤 404: 目标基站 （ HeNB2或者 HeNB3或者 HeNB4或者 MeNB5 ) 接收到家庭基站网关或者家庭基站网管系统发送的邻区配置消息， 把 Celll 的信息加到本地邻区列表中。 各基站在更新邻区列表之前可以判断本地邻区列表中是否保存了 Celll 的小区信息， 没有时再更新。
实施例 3
通过核心网向其他小区配置邻接小区信息， 具体过程如图 5所示 步骤 501 , 家庭基站 HeNBl上电时扫描 Celll的邻接小区， 扫描得到邻 接小区的小区信息； 步骤 502, 家庭基站 HeNBl通过 S1接口消息把邻接小区的小区信息通 过家庭基站网关发送给 MME, 具体消息可以是 eNB 配置传输消息 （ eNB CONFIGURATION TRANSFER )或者其他 UE无关消息， 为描述方便在本实 施例中称为 "上行邻接小区信息传输消息" ； 上述邻接小区信息传输消息中包含当前小区（即 Celll )信息和邻接小区 (单个小区或者小区列表）信息， 小区信息可能包括 PCI、 小区全局标识、 跟踪区码等参数。 上述邻接小区可以是家庭基站小区， 也可以是宏小区。 步骤 503 , MME接收到上行邻接小区信息传输消息， 获取其中包含的邻 接小区信息， 并且根据这些信息 （比如小区全局标识或者跟踪区码或者二者 的组合）找到对应的目标基站； MME通过预先配置或者上电时的交互获知各小区信息与对应基站的对 应关系。
步骤 504, MME通过 S1接口消息把当前基站（即 HeNBl )的小区信息 发送给目 标基站， 具体消息可以是 MME 配置传输消息 （ MME CONFIGURATION TRANSFER )或者其他 UE无关消息， 为描述方便在本实 施例中称为 "下行邻接小区信息传输消息" ；
MME到基站的 S1接口消息， 对不同类型的目标基站发送方式不同： 对 存在家庭基站网关的情况， S1接口消息通过家庭基站网关发送给对应的家庭 基站； 不存在家庭基站的情况， 以及宏基站， S1接口消息直接发送给对应的 基站， 具体的处理过程见步骤 504a、 504b, 504c和 504d, 此处不再赘述。
步骤 505 , 目标基站接收到下行邻接小区信息传输消息， 把其中包含的 小区信息加入到本地的邻区列表中。
实施例 4
家庭基站根据 UE测量报告确定邻接小区， 然后上报给核心网， 具体过 程如图 6所示。
步骤 601 , HeNBl为 UE配置测量控制， UE上报邻区测量报告， 其中包 含邻区参数列表， 邻区参数包括 PCI、 小区全局信息 （条件可选， 包含小区 全局标识、 PLMNID、 跟踪区码）和信号质量等；
上述小区全局信息条件可选的含义是： UE根据网络配置的测量控制类 型和目的确定是否上报小区全局信息。
步骤 602, HeNBl获取步骤 601所属测量报告中各邻区 PCI, 首先根据 PCI在本地保存的邻区列表中查找， 如果找到对应的小区则不需要新增邻接 小区配置； 如果查找不到， 则增加邻接小区配置， 同时向核心网发送通知消 息； 上述 "向核心网发送通知消息"是指向 MME发送 S1接口消息， 具体消 述方便在本实施例中称为 "上行邻接小区信息传输消息" ， 消息中包含当前 小区（即 Celll )信息和邻接小区（单个小区或者小区列表）信息， 小区信息 包括 PCI、 小区全局标识、 跟踪区码等参数。
如果 UE发送的测量报告中不包含小区全局标识， 则需要向 UE配置上 报小区全局标识的测量控制， 或者根据 PCI向家庭基站网关或者家庭基站网 络管理系统请求该小区的小区全局标识。
步骤 603: MME接收到上行邻接小区信息传输消息， 获取其中包含的邻 接小区信息， 并且根据这些信息找到对应的目标基站；
步骤 604: MME通过 S1接口消息把当前基站（即 HeNBl )的小区信息 发送给目标基站 ,具体消息可以是 MMECONFIGURATION TRANSFER或者 其他 UE无关消息， 为描述方便在本实施例中称为 "下行邻接小区信息传输 消息" ， 具体的处理过程见步骤 604a、 604b, 604c和 604d, 此处不再赘述。
步骤 605: 目标基站接收到下行邻接小区信息传输消息， 把其中包含的 小区信息加入到本地的邻区列表中。
实施例 5
对应方法 2的具体实施方式。 本实施例中， 当前小区称为源小区， 邻接 小区称为目标小区。
步骤 701 , UE通过家庭基站接入到移动网络并发起业务；
步骤 702, 家庭基站接收到 UE对邻区的测量报告， 做切换判决， 决定 向相邻宏基站发起 S1切换过程；
步骤 703 , 家庭基站向核心网发送切换要求（Handover Required ) , 其 中包含目标标识 （ Target ID , 包括基站身份标识和跟踪区标识） ， 以及源到 目的端的透传信息字段 ( Source to Target Transparent Container )等信息； 切换请求中还可以携带源家庭基站小区类型指示， 通过上述家庭基站小 区类型目标基站可以获知源小区是家庭基站小区， 还可能获取源小区的接入 控制类型比如开放式、 封闭式或者混合式。 也就是说， 小区类型指示中包含 源小区类型和 /或源小区接入控制类型。
上述 Source to Target Transparent Container中包含源小区的小区信息（比 如 PCI、 小区全局标识、 跟踪区标识等） 。
步骤 704 , 核心网根据目标标识找到相应的目的基站， 并发送切换请求 到目的基站， 其中至少包含需要切换的承载参数以及源到目的端的透传信息 字段 ( Source to Target Transparent Container )等信息； 上述家庭基站小区类型指示和 Source to Target Transparent Container i)L 是步骤 703中的同名字段， 核心网不对该字段内容做修改。 如果切换请求中还携带小区类型指示， 则核心网向目的基站发送的切换 请求中也携带有小区类型指示。
步骤 705 , 目标基站接收到切换请求消息， 根据消息指示执行切换过程， 并更新本地邻区列表；
更新本地邻区列表时， 可先判断邻区列表中是否有源小区的小区信息， 没有时， 将切换请求中包含的源小区的小区信息添加至邻区列表中。
如果切换请求中还携带有小区类型指示， 则目标基站根据预先配置的条 件以及小区类型指示中所指示的类型更新本地邻区列表。 例如小区类型指示 表示源小区类型为家庭基站且接入类型为开放式或者混合式时， 目标家庭基 站才获取源小区信息， 将其加入到本地保存的邻区列表中。 具体的条件有多 种组合， 此处不再——赘述。 步骤 706, 执行其余切换过程。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成， 所述程序可以存储于计算机可读存储介质中， 如只读 存储器、 磁盘或光盘等。 可选地， 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地， 上述实施例中的各模块 /单元可以釆用 硬件的形式实现， 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。 当然， 本发明还可有其他多种实施例， 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 工业实用性 通过本发明方法， 可以及时地为基站配置邻区信息， 从而减少了由 UE 上报部区带来的对 UE电量的损耗并且提高了测量效率。 本发明同时适用于 3G家庭基站系统和 LTE家庭基站系统。
