- the existing wireless access networks are generally deployed as macro base stations.
- the macro base stations have large coverage areas and can support high-speed mobile terminal characteristics.
- the macro base station throughput is constant, although the coverage area is large, the actual access can be simultaneously accessed.
- the number of users is limited, and the bandwidth of the macro base station needs to be shared among many users, so the bandwidth obtained by actual users is not necessarily ideal, especially when the traffic is relatively busy.
- the home base station is in the Worldwide Interoperability for Microwave Access ( Worldwide Interoperability for Microwave Access, Referred to as WiMAX), the system is called Femto or WiMAX Femto Access Point (WFAP).
- WiMAX Worldwide Interoperability for Microwave Access
- the home base station is characterized by a small coverage, serving only a small number of terminals, and accessing the home base station access gateway by using the existing broadband connection of the user. Obviously, the terminal accessing the home base station can obtain the high bandwidth service.
- CSG CSG-Closed Model
- the so-called private type is to provide services only to specific terminals or users; the public type is the same as the macro base station, there is no access to the terminal or user Restriction; Hybrid type is to limit the access terminal or user, but to provide high priority services to specific terminals or users.
- the self-organizing network management for the home base station mainly involves air-to-air communication. Parameters, such as radio frequency (RF) parameters, physical layer (PHY), self-organizing network Network parameters, management of Media Access Control (MAC) parameters.
- RF radio frequency
- PHY physical layer

- the base station list; the neighboring home base station information acquired by scanning also needs to be synchronized to the SON server, so that the SON system maintains the topology information of the entire network in real time. In this way, the home base station obtains its neighbor list in the initialization process, including information of the neighboring macro base station and the home base station.
- Self-optimization means that the home base station adjusts the air interface parameters according to the collected information in the process of providing services, so as to achieve capacity and coverage optimization, mobility management optimization, and reduce interference optimization.
- Self-healing means that when the home base station fails or fails to provide satisfactory service, the self-organizing network management method automatically eliminates the fault or minimizes the impact of the fault.
- the neighboring area automatically optimizes; although the home base station can obtain the initial neighbor information during the initialization process of the home base station, but the network topology changes or the base station fails, or the neighbor list information during the initialization process. Incomplete, it is necessary to update the neighbor list information in real time through the neighbor list self-optimization.

现有无线接入网络一般部署都是宏基站， 宏基站具有覆盖面积大， 能够 支持高速移动终端特性； 但是由于宏基站吞吐量是一定的， 虽然其覆盖面积 大， 但实际能够同时接入的用户数是有限的， 而且宏基站的带宽需要在众多 用户间共享， 因此实际用户得到的带宽并不一定很理想， 尤其是在话务比较 繁忙的时候。 考虑用户大部时间在家中或者办公室， 而且处于低速移动， 具 有高带宽需求， 因此在无线技术中引入家庭基站并成为研究热点， 家庭基站 在! ¾波存取全球互通 ( Worldwide Interoperability for Microwave Access, 简称 WiMAX ) 系统中称为 Femto 或 WiMAX 家庭基站接入点 （ WiMAX Femto Access Point, 简称 WFAP ) 。
家庭基站的特点是覆盖范围小， 只为少数终端服务， 而且利用用户现有 宽带连接接入家庭基站接入网关， 显然， 接入家庭基站的终端能够得到高带 宽服务。
家庭基站可以分为三种类型： 私有类型 （CSG-Closed Model, CSG为
Closed Subscribers Group ) , 公有类型 （Open Model ) , 混合类型 (CSG-Open Model) 0 所谓私有类型就是只给特定终端或用户提供服务； 公有类型就是和 宏基站一样， 对接入的终端或用户没有限制； 混合类型就是对接入的终端或 用户没有限制， 但是对特定终端或用户提供高优先级的服务。
由于家庭基站数目众多， 传统宏基站管理方法已经不完全适用， 而是釆 用自组织网络（Self-Organized Network, 简称 SON )方法进行管理； 对家庭 基站釆用自组织网络管理主要涉及对空口涉及的参数， 例如对射频 （Radio Frequency, 简称 RF )参数， 物理层（Physical Layer, 简称 PHY ) 自组织网
络参数， 介质访问控制层 (Media Access Control, 简称 MAC)参数的管理。 自 组织网络管理的方法主要包括三部分： 自配置（ Self-Configuration ) , 自优化 ( Self-Optimization ) , 自愈合 ( Self-Healing ) 。
自配置主要是家庭基站在接入宽带或者开机进行初始化过程中， 获取空 口涉及的初始配置参数， 这些参数中最重要的包括邻区列表。 例如 WFAP在 初始化过程中， 可以从网络侧服务器（这里服务器指的是网管系统， 或者实 现 SON功能的服务器 )得到其宏基站邻区列表， 并可以工作在终端模式扫描 周围的家庭基站来获取家庭基站列表； 其中通过扫描获取的邻区家庭基站信 息也需要同步到 SON服务器，以便 SON系统实时维护整个网络的拓朴信息。 这样家庭基站在初始化过程就得到其邻区列表， 其中包括邻区宏基站和家庭 基站的信息。
自优化指家庭基站在提供服务的过程中， 根据釆集的信息， 对空口参数 进行调整， 以便实现容量和覆盖优化、 移动性管理优化， 降低干扰优化。
自愈合指家庭基站出现故障或者不能提供满意服务时， 由自组织网络管 理方法自动排除故障， 或者将故障影响降低到最低。
在自优化过程中，还包括邻区自动优化； 虽然在家庭基站初始化过程中， 家庭基站可获取初始邻区信息， 但是此后由于网络拓朴变化或者基站出现故 障， 或者初始化过程中邻区列表信息不完整， 都需要后续通过邻区列表自优 化来实时更新邻区列表信息。 邻区列表自动更新对保证整网切换性能尤其重 要， 也是切换优化相关的。
目前 WiMAX论坛中对家庭基站只是讨论家庭基站初始化过程中的自动 配置， 还没有涉及到邻区列表自动更新。 发明内容

附图概述
图 1是实施例一中 SON服务器发起家庭基站邻区列表更新的流程图; 图 2是实施例二中家庭基站发起基站邻区列表更新的流程图。
本发明的较佳实施方式
家庭基站中保存有自身的邻区列表的信息， SON服务器中保存有网络拓 朴结构信息，此拓朴结构信息中包括 SON服务器所管理的基站间的邻区关系 的信息， 即所管理的基站的邻区列表。
无论是家庭基站中保存的邻区列表，还是 SON服务器保存的整个网络中 基站之间的邻区关系都涉及到邻区基站的信息。 家庭基站保存的邻区列表中 存放的是可以从该家庭基站切换到的邻区基站的信息， 此邻区基站可以是宏 基站， 也可以是其它家庭基站， 还可以是其它类型的基站。 这些邻区基站可 以和此家庭基站属于同一个接入网运营商 （NAP ) , 也可以属于不同 NAP, 不同的邻区基站也可以属于不同 NAP。 邻区基站的信息至少包含如下信息之 一： 基站标识信息、 频率信息、 接入网运营商标识、 是否处于工作状态、 是 否允许切换。 其中， 基站标识信息至少包含如下信息之一： 基站 MAC层标 识（BS ID ) 、 前缀索引和小区标识（Cell ID ) 。
基站之间的邻区关系一般遵循互配置原则， 即基站 A如果^ ^站 B的邻 区，那么基站 B也^^站 A的邻区； 即当基站 A把基站 B添加到其邻区列表 中时， 那么基站 B也需把基站 A添加到其邻区列表中； 当基站 A把基站 B 从其邻区列表中删除时， 那么基站 B也需要把基站 A从其邻区列表中删除。
当家庭基站在初始入网中获取初始邻区信息后， 其邻区列表可能还需要 更新。家庭基站的邻区列表的更新可以由此家庭基站自己触发，也可以由 SON 服务器触发。 下面通过两个实施例来分别说明这两种情况。
实施例一：
实施例一中描述 SON服务器发起基站邻区列表更新的流程。 SON服务 器检测到基站邻区列表变化或需要更新时， 更新自身保存的整网的基站之间 的邻区关系， 并且指示需要更新邻区列表的基站更新其邻区列表。 邻区列表 中需要更新的基站可以是以下类型之一： 宏基站、微基站、微微基站（Pico )、 家庭基站和其它类型的基站。
本发明可典型应用于需要更新的基站是家庭基站的情况。 下面参照图 1 , 具体说明 SON服务器发起家庭基站邻区列表更新的方法， 具体包括以下步
骤：
步骤 101 , SON服务器检测到家庭基站邻区信息 （或邻区列表中的基站 信息） 变化或需要更新；
SON服务器更新其保存的网络拓朴结构信息时， 或者， SON服务器在做 邻区互配置检查时，可检测到家庭基站部区列表中的基站信息是否需要更新。 SON服务器可以知晓整个网络中基站的状态，包括基站的状态或状态变化（例 如处于工作状态的基站（包括新增一个基站，或从非工作状态变为工作状态）； 例如处于非工作状态的基站（包括 Backhaul中断， 或从工作状态变为非工作 状态） ） ， 也可以知晓需新增或删除的基站。
SON服务器检测到以下情况时判断家庭基站邻区列表中的基站信息需要 更新：
( 1 )某基站从工作状态变化到非工作状态， 导致基站处于非工作状态的 原因可能是链接到基站的链路出现故障、 基站本身出现故障、 基站断电、 基 站关机等；
( 2 )新增某个基站； 此新增的基站是指新添加的处于正常工作状态的基 站；
( 3 )删除某个基站；
( 4 )某基站从非工作状态变化到工作状态， 例如基站从故障状态恢复到 正常工作状态。 SON服务器检测到家庭基站邻区列表中的基站信息需要更新后， 更新自 身保存的网络中基站的邻区关系。
步骤 102, SON服务器向需要更新邻区列表的家庭基站发送用于指示更 新邻区列表的指示消息， 通知此家庭基站更新邻区列表；
SON服务器向家庭基站发送的消息中包含以下信息之一： 更新后的邻区 列表信息， 邻区列表的更新信息。
邻区列表的更新信息包含如下信息至少之一： 邻区列表中需要增加的邻 区基站及其信息； 邻区列表中需要删除的邻区基站及其信息； 邻区列表中需 要更新基站信息的邻区基站的更新信息。
由于 SON服务器中保存有 Femto的位置信息， 因此如果当网络中新增宏 基站时，那么 SON服务根据拓朴结构可知新增宏基站覆盖范围下或有重叠覆 盖关系的 Femto, 因此 SON服务器能够知道新加入的处于工作状态的宏基站 可以作为哪些 Femto的邻区， 从而触发相关的 Femto在其邻区列表中增加该 宏基站的信息。 这个过程也适用于触发相关的宏基站在其邻区列表中增加该 宏基站的信息。
由于 SON服务器保存有网络中基站的邻区关系，因此当网络中删除某个 基站（包括宏基站或 Femto ) 时， SON服务器能够知道哪些基站（宏基站或 Femto )的邻区列表受到影响， 从而触发邻区列表受到影响的基站从其邻区列 表中删除所述删除基站的信息。
SON服务器能够实时探测网络中基站（包括宏基站或 Femto ) 的工作状 态， 当 SON服务器发现某基站从工作状态变化为非工作状态时， 显然该处于 非工作状态的基站不能用作切换的目标基站； 因此需要从相关基站的邻区列 表中删除处于非工作状态的邻区基站， 或者在邻区列表中标记该基站处于非 工作状态， 或者在邻区列表中标记该基站不能用于切换的目标基站。 反之亦 然， 即 SON服务器发现某基站从非工作状态变化为工作状态， 则做上述操作 对应的相反的操作。
由于 SON服务器保存有网络中基站的邻区关系， 因此当 SON服务器探 测到网络中某个基站 （包括宏基站或 Femto )从工作状态变化为非工作状态 时， SON服务器能够知道哪些基站（包括宏基站或 Femto ) 的邻区列表受到 影响， 从而触发邻区列表受到影响的基站更新其邻区列表， 向邻区列表中包 含此基站的基站 （包括宏基站和家庭基站）发送指示消息， 指示其更新邻区 列表； 并且向邻区列表中包含此基站的基站（包括宏基站和家庭基站）发送 的指示消息中携带以下信息中至少一个： 从邻区列表中删除处于非工作状态 的基站信息； 或者在邻区列表中标记该基站处于非工作状态， 或者从邻区列 表中更新该基站的信息为不能作为切换的目标基站。反之亦然， 即 SON服务 器发现某基站从非工作状态变化为工作状态， 则做上述操作对应的相反的操 作。
步骤 103 , 家庭基站收到步骤 102所述的消息后， 更新其邻区列表；
如果家庭基站收到时更新后的邻区列表， 则直接更新其邻区列表； 如果 收到的是部区列表的更新信息， 则根据更新信息更新原有邻区列表。
步骤 104, 家庭基站向 SON服务器发送指示此家庭基站的更新结果的消 息， 即通知 SON服务器其更新的结果。 家庭基站进行邻区列表更新的结果为 成功或失败。
步骤 104可以为可选步骤。
上述方法中， SON服务器向家庭基站发送指示此家庭基站的更新结果的 消息之前， 还需先更新其网络拓朴结构信息中基站的邻区关系， 更新后的邻 区关系同更新后邻区列表信息保持一致， 即包括基站新增了邻区基站， 或基 站删除了邻区基站， 或基站的邻区基站信息发生改变。
上述步骤也适用于 SON服务触发的更新宏基站邻区列表的过程。
具体实施例一：
当 SON探测到删除某基站时， SON根据自身保存的网络拓朴结构， 知 道删除这个基站影响到哪些基站的邻区列表； 一方面更新自身保存的网络中 的基站之间邻区关系， 同时也发送消息给受到影响的基站， 所述消息包含更 新后的邻区信息或邻区列表的更新信息， 用于指示更新其邻区列表或从其邻 区列表中删除该基站信息。
具体实施例二：
当 SON探测到增加某基站时， SON根据自身保存的网络拓朴结构， 知 道增加的这个基站影响到哪些基站的邻区列表； 一方面更新自身保存的网络 中的基站之间邻区关系， 同时也发送消息给受到影响的基站， 所述消息包含 更新后的邻区信息或邻区列表的更新信息， 用于指示更新其邻区列表或从其 邻区列表中增加该基站信息。
具体实施例三：
当 SON探测到某基站从工作状态变化为非工作状态时，可以有两种处理 方法。
方法一： 把该基站当做删除基站情形， 做同样的处理， 即 SON根据自身 保存的网络拓朴结构， 知道处于非工作状态的这个基站影响到哪些基站的邻
区列表。 一方面更新自身保存的网络中的基站之间邻区关系， 同时也发送消 息给受到影响的基站， 所述消息包含更新后的邻区信息或邻区列表的更新信 息， 用于指示更新其邻区列表或从其邻区列表中删除该不处于工作状态的基 站信息。
方法二： SON根据自身保存的网络拓朴结构， 知道这个处于非工作状态 的这个基站影响到哪些基站的邻区列表； 一方面更新自身保存的网络中的基 站之间邻区关系， 即标记该基站状态为非工作状态， 即不能用于切换。 同时 也发送消息给受到影响的基站， 所述消息包含更新后的邻区信息或邻区列表 的更新信息， 用于指示更新其邻区列表或从其邻区列表中更新该基站信息， 用于表明该基站不处于工作状态和 /或不能用于切换。
针对上述实施例一， 本发明还公开了一种自组织网络服务器， 上述自组 织网络服务器设置为， 检测到家庭基站邻区信息发生变化或需要更新时， 向 需要更新邻区信息的家庭基站发送用于指示更新邻区信息的指示消息； 以便 上述需要更新邻区信息的家庭基站根据收到的指示消息更新其保存的邻区信 息。 上述自组织网络服务器的功能与上述方法实施例一中的自组织网络服务 器的功能相同， 在此不赘述。
实施例二：
实施例二中描述家庭基站发起邻区列表更新的流程。 家庭基站 A为宏基 站或 Femto , 家庭基站 B为宏基站或 Femto。 如图 2所示， 包含以下步骤： 步骤 201 , 家庭基站 A检测到邻区信息 （或邻区列表中的基站信息） 变 化或需要更新；
家庭基站能够检测到现有邻区列表中没有包含的邻区基站及其信息， 即 探测到可以新增到其邻区列表中的新的邻区基站及其信息。
家庭基站可以通过如下方式发现当前邻区列表中没有包含的邻区： 1.通 过其服务的终端上报的消息发现， 即终端上报如下消息至少之一发现新增邻 区基站： 扫描结果上报消息， 或切换请求消息， 或切换指示消息， 或上下文 请求消息等； 即当这些消息中出现了邻区列表中没有包含的邻区基站， 则可 以认为基站通过终端上报消息探测到了新的邻区基站。 2. 家庭基站在后续
扫描邻区基站过程中发现新的邻区基站。
家庭基站通过以下方式之一检测到邻区列表中的基站信息发生变化： 通 过终端上报的消息； 或通过自身对邻区基站的扫描。 所述终端上报消息至少 包括如下消息之一： 扫描结果报告消息、 切换请求消息、 切换指示消息、 上 下文请求消息。
家庭基站可能还有其它方式探测到邻区列表中邻区基站不能作为邻区基 站， 即需要从邻区列表中删除某邻区基站。
家庭基站检测到邻区列表中的基站信息发生变化的情况至少包括以下情 况中的一种： 邻区列表中需要增加邻区基站及其信息； 或邻区列表中需要删 除邻区基站及其信息； 或邻区列表中需要更新邻区基站的信息。
如果 WFAP探测到邻区列表发生改变时， 家庭基站可以直接更新其邻区 列表或者等待 SON发送指示消息后再更新其自身的邻区列表。
步骤 202,家庭基站 A向 SON服务器发送用于指示更新邻区列表的消息， 通知更新其邻区列表；
家庭基站 A向 SON服务器发送的用于指示更新邻区列表的消息包含更 新后的邻区列表或邻区列表的更新信息； 邻区列表的更新信息可包括以下信 息中至少的一种： 新增邻区基站及其信息； 删除的邻区基站及其信息； 基站 信息需要更新的邻区基站及其更新信息。
步骤 203 , SON服务器收到家庭基站 A发送的消息后， 向此家庭基站 A 发送收到该消息的确认消息；
此步骤 203为可选步骤。
步骤 204, SON服务器检测需要进行邻区列表更新的基站（包括宏基站 和家庭基站） ， 并更新自身保存的网络中基站（包括宏基站和家庭基站） 的 邻区信息；
SON服务器检测到的需要进行邻区列表更新的基站可以是多个基站， 需 要进行邻区列表更新的基站可以是宏基站， 可以是家庭基站， 还可以是宏基 站和家庭基站。
SON服务器根据收到的信息来更新网络中基站的邻区关系； 另外， SON
服务器根据该信息来发现其它基站的邻区关系是否受到影响 （根据邻区互配 置或其它方法） ， 如果存在邻区关系受到影响的其它基站， SON服务器还要 通知其他基站更新其邻区列表。
需要进行邻区列表更新的家庭基站至少包括以下基站之一： 向所述自组 织网络服务器发送指示消息的家庭基站， 向所述自组织网络服务器发送的指 示消息中指示的新增的邻区基站； 向所述自组织网络服务器发送的指示消息 中指示的删除的邻区基站； 根据邻区互配置检查表检测到的需更新邻区列表 的家庭基站。
SON服务器检测邻区列表中需要进行信息更新的家庭基站时， 还考虑互 配置原则。例如，基站 A探测到新增邻区 B,那么 SON服务器收到该信息后， 不仅是基站 A需要新增邻区 B, 而且基站 B也需要新增邻区 A。 基站 A探测 到需要删除邻区 B, 那么 SON服务器收到该信息后， 不仅^ ^站 A需要删除 邻区 B, 而且基站 B也需要删除邻区 A。
步骤 205, SON服务器向需要进行邻区列表更新的基站（可以是宏基站 和 /或家庭基站）发送用于指示邻区列表更新的消息；
图 2中需要进行信息更新的家庭基站为基站 A和基站 B,只作示例之用， 在实际应用中， 需要进行信息更新的家庭基站可以有多个。
用于指示邻区列表更新的消息中包含更新后的邻区列表信息或邻区列表 的更新信息。 其中所述邻区列表的更新信息包括以下信息中至少之一： 在邻 区列表中增加邻区基站及其信息， 或在邻区列表中删除邻区基站及其信息， 或在邻区列表中更新某邻区基站的基站信息。
步骤 206, 家庭基站 A和家庭基站 B更新其邻区列表中的基站信息。 ； 如果收到的消息是更新后的邻区列表， 则直接釆用新的邻区列表即可； 如果收到的是邻区列表的更新信息， 则根据邻区列表的更新信息更新原有邻 中增加邻区基站及其信息， 在邻区列表中删除邻区基站及其信息， 在邻区列 表中更新邻区基站的基站信息。
步骤 207,家庭基站 A和家庭基站 B向 SON服务器发送指示更新结果的
消息。
邻区列表更新的结果为成功或失败。
步骤 207是可选步骤。
上述方法中， SON服务器在发送消息给部区列表需要更新的基站之前， SON服务器自身更新网络中基站间的邻区信息； 更新后邻区信息同基站更新 后邻区信息 （或邻区列表信息）保持一致， 即包括基站新增了邻区基站， 或 基站删除了邻区基站， 或基站的邻区基站信息发生改变。
基站更新其自身邻区列表时刻是以下之一： 基站探测到需要更新其邻区 列表时，基站直接更新其邻区列表； 或基站收到 SON服务器的消息指示更新 其邻区列表后再更新其邻区列表。
上述步骤 204中如果 SON服务探测宏基站邻区列表需要更新，则还可以 触发宏基站邻区列表更新过程。
上述步骤也适用于宏基站触发的邻区列表的过程。
上述实施例一、 二中实体间传递的消息可以釆用 TR069, 简单网络管理 协议 (Simple Network Management Protocol, 简称 SNMP), 有线电缆数据服务 接口规范（ Data-Over-Cable Service Interface Specifications, 简称 DOCSIS )等 协议承载。 上述过程中的 SON服务器也可以被网络管理系统 （Network Management System, 简称 NMS )所代替。
需要说明的是， 本发明中的邻区信息、 邻区列表信息、 邻区列表中的基 站信息是等价的。
针对上述实施例二， 本发明还提供了一种家庭基站， 上述家庭基站设置 为， 检测到邻区信息发生变化或需要更新时， 向自组织网络服务器发送用于 指示更新邻区信息的指示消息； 以及根据收到的指示消息更新其保存的邻区 信息。
上述家庭基站的功能与上述方法实施例二中的家庭基站的功能相同， 在 此不赘述。
本发明的技术方案可及时地、 自动地更新系统中家庭基站的邻区列表， 较好地提高了系统的网络性能。
本发明实施例中提到的邻区列表是部区信息的一种表现形式， 本领域的 技术人员应该明了， 上述实施例中釆用邻区列表只是示意性地描述本发明的 技术方案。
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。
本发明不仅适用与家庭基站邻区信息更新， 也适用于其它类型基站的邻 区信息 （即邻区列表） 的更新。
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。
