本发明涉及通信领域, 尤其涉及一种获取控制节点信息的方法、 设备及系统。 背景技术
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, 长期演进升级 ) 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 (施主小区 )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。 SI接口提供访问无线接入网中的无线资源, 包括控制平面功能 和用户平面功能。 S1接口的控制面接口( S1-MME )提供 eNB与 MME 之间的应用协议以及用于传输应用协议消息的信令承载功能; S1接 口的用户面接口 (S1-U )提供 eNB与 S-GW之间的用户面数据传输 功能。 S1接口主要功能包括: E-RAB ( E-UTRAN Radio Access Bearer, 无线接入承载) 管理功能; 移动性管理功能; 寻呼功能; NAS ( Non- Access Stratum , 非接入层) 信令传输功能; LPPa ( LTE Positioning Protocol A , LTE定位协议 A )信令传输功能; S 1接口管 理功能; 网络共享功能; 漫游和区域限制支持功能; NAS节点选择 功能; 初始上下文建立功能; UE上下文修改功能; MME负荷均衡 功能; 位置上报功能; PWS ( Public Warning System, 公共告警系统) 消息传输功能; 过载功能; RAN ( Radio Access Network, 无线接入 网)信息管理功能; 配置传输功能; S1 CDMA2000隧道功能等。
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 eNB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管理和错误控制功 能等。
RN启动过程如图 2所示, 可以描述为: RN与 DeNB之间建立 RRC ( Radio Resource Control,无线资源控制协议)连接; RN向 MME 发送附着请求; MME从 HSS ( Home Subscriber Server, 归属用户服 务器)处获取 RN的签约数据,对 RN进行认证;如果认证通过, MME 在 S-GW/P-GW中为 RN建立默认承载, 并向 DeNB发送初始上下文 建立请求消息, 在 DeNB中建立 RN的上下文; 随后 DeNB向 RN发 送 RRC连接重配置消息, 携带 MME发给 RN的附着接受消息; RN 返回 RRC连接重配置完成进行确认。 这样, RN建立了基本的 IP连 接。 然后 O&M ( Operation and Maintenance, 运行和维护)将节点配 置信息下载到 RN, 对 RN进行配置。 RN再建立必要的 SI接口和 X2接口后, 就可以像基站一样正常工作了。
UE接入 RN进行附着的过程如图 3所示, UE与 RN之间建立 RRC连接, UE向 MME发送附着请求消息( Attach Request )。 RN将 这条 NAS消息携带在初始 UE消息 ( Initial UE Message ) 中发送给 DeNB。 DeNB收到这条消息后, 将其中的 eNB UE S1-AP ID1修改为 自己为 UE分配的 eNB UE Sl-AP ID2 , 并根据 GUMMEI ( Globally Unique MME Identifier, 全球唯一 MME标识 )信息指示或者 MME 选择功能将这条消息发送到合适的 MME。 MME收到初始 UE消息后 , 为该 UE分配一个 MME UE Sl-AP ID3 ,与收到的 eNB UE Sl-AP ID2 对应存储起来。 MME UE Sl-AP ID3在一个 MME内唯一标识一个 UE, 此后 MME根据收到的 S1-AP消息中的 MME UE Sl-AP ID3来 区分 UE。 MME向 RN所属的 DeNB发送初始上下文建立请求消息 ( Initial Context Setup Request ), DeNB将收到的 MME UE Sl-AP ID3 替换为自己分配的 MME UE Sl-AP ID4,和自己为 UE分配的 eNB UE Sl-AP ID2、 RN为 UE分配的 eNB UE Sl-AP ID 1一起对应存储起来。 然后 DeNB将初始上下文建立请求消息转发给 RN, 用于在 RN中建 立 UE上下文。 RN将自己为 UE分配一个 eNB UE Sl-AP ID1和收到 的 MME UE Sl-AP ID4一起对应存储起来。 RN随后向 MME发送初 始上下文建立响应消息进行确认。 UE附着过程中, 各个节点存储的 对应关系见表 1。 在后续的过程中, 通过 UE附着过程中建立的映射 关系, DeNB可以根据 UE AP-ID信息, 找到 R-UE (指代 Relay下 UE )连接的 MME信息 ( GUMMEI )。 GUMMEI信息是 MME的全 球唯一标识, 由 PLMN ( Public Land Mobile Network, 公共陆地移 动网络) ID、 MME Group ID和 MME code组成, 每一个 GUMMEI 对应唯——个 MME。其中,各节点存储的对应关系列表如表 1所示。 表 1
Figure imgf000005_0001
通过以上过程可以获知, DeNB具有 S1/X2 AP代理功能, RN和 DeNB之间只有一个 S1接口和一个 X2接口, DeNB与多个 MME/S-GW相连, 由 DeNB负责 R-UE的 MME控制节点选择功能, RN并不知道 R-UE连接的 MME信息。 但是, RN需要获知 R-UE连 接的 MME信息用于判断切换类型和 MME正确寻址等, 因此需要一 种能够让 RN获知 R-UE连接的 MME信息的方案。 发明内容
