由于基站通常具有较高的造价， 在 3G ( 3rd-generation, 第三代 移动通信）技术的发展中， 大量基站的建造会导致较高的布网成本。 为了降低成本， 中继逐渐被引入到蜂窝系统中， 增加基站信号的覆盖 范围。 图 la为 LTE-A ( LTE-Advanced, 演进的 LTE ) 系统引入 RN ( Relay Node , 中继节点）后的网络架构， RN通过 DeNB ( Donor Evolved Node B , 施主基站 ) 下的 donor cell接入到核心网， 和核心 网没有直接的有线接口， 每个 RN可以控制一个或多个小区。 在此架 构下， UE ( User Equipment , 用户终端） 和 RN之间的接口称为 Uu 接口， 而 RN和 DeNB之间的接口称为 Un接口。 一个 DeNB下面可 以连接多个 RN , 而一个 RN只能连接到一个 DeNB上。
图 lb为引入 RN后的 LTE-A系统的结构图。 S1接口一边连接 E-UTRAN ( Evolved UTRAN, 演进后的通用陆地无线接入网） 中的 节点 eNB , —边连接 EPC ( Evolved Packet Core , 演进后的分组核心 网）中的节点 MME/S-GW ( Mobility Management Entity, 移动性管理 实体 / Serving Gateway, 服务网关）， 或者一边连接 eNB , —边连接 RN。 X2接口位于 E-UTRAN中的节点 eNB之间或者 eNB与 RN之 间， eNB之间具有多对多连接关系的 X2接口， 在一定区域内可能存 在所有的 eNodeB之间都具有 X2连接。 X2接口存在的主要目的是支 持连接状态下的 UE的移动性管理功能； 除此之外， X2接口主要功 能还包括负载管理功能、 小区干扰协调功能、 一般的 X2管理功能和 错误控制功能等。
在 LTE ( Long Term Evolution, 长期演进） 系统中， 当一个 eNB 需要 X2接口应用配置时，比如增减或修改小区配置，则需要进行 eNB 配置更新过程， 如图 2所示。 eNB l向 eNB2发送 eNB Configuration Update ( eNB配 置更新） 消息， 包含增减的小区 PCI ( Physical Cell Identifier, 物理小区标识）、 ECGI ( E-UTRAN Cell Global Identifier, E-UTRAN小区全球标识）、 频率等信息， 如果 eNB2能够接受这次更 新， 则更新自己存储的 eNB l的配置信息， 并向 eNB l返回 eNB配置 更新确认消息。 每个小区都具有一个全球唯一的标识 ECGI , ECGI 由 PLMN ( Public Land Mobile Network , 公共陆地移动网络） ID、 eNB ID和 cell ID三部分组成， 一共 52比特， 其中 PLMN ID和 eNB ID组成了 eNB的全球唯一标识 Global eNB ID , 共 44比特， 剩余 8 比特为 cell ID。 目前， 小区的 ECGI—般由 OAM ( Operation Administration and Maintenance , 操作维护管理 )分配。
目前在 LTE系统中， 通过 Χ2连接建立过程或 eNB配置更新过 程，基站仅能够获得邻基站的接口连通性信息， 包括邻基站管理了哪 些小区、以及这些小区的标识、频率等信息。 引入 RN后， 由于 DeNB 具有 S1/X2 AP ( Application Protocol , 应用协议 )代理功能， RN和 DeNB只有一个 X2接口和一个 S1接口， 即 RN只能通过上述 X2连 接建立过程或 eNB配置更新过程获得 DeNB管理的小区信息。但是， 在切换、 ANR ( Automatic Neighbour Relation, 自动邻区关系）、 干扰 协调和负荷均衡等过程中， RN需要获知 DeNB与其它 eNB的接口连 通性信息。 为了解决该问题， 需要一种新的获取接口连通性的机制。 发明内容

步骤 703 , 当 R-UE发生切换时， RN根据保存的 DeNB邻基站 配置信息， 判断目标小区与源 RN是否有 X2接口以及是否同属于一 个 MME POOL , 如果满足条件， 则向目标小区发送 X2切换的 Handover Request (切换请求 ) 消息。
步骤 704 , DeNB收到 Handover Request消息后， 发现 DeNB与 目标小区没有 X2接口，则向 RN返回 Handover Preparation Failure消 息， 携带失败原因为 X2 not available。
步骤 705 , RN根据 Handover Preparation Failure消息更新存储的 DeNB与邻基站的 X2接口连通性信息。 例如， RN删除 DeNB与邻 基站的 X2接口连通性信息中失败原因为 X2 not available的 DeNB的 邻基站的配置信息。 实施例七
