Description

一种中继节点小区参数的配置方法及装置 技术领域
本发明涉及无线通信技术领域， 尤其涉及一种中继节点 （Relay Node, 简称 RN ) 小区参数的配置方法及装置。 背景技术
为了满足日益增长的大带宽高速移动接入的需求， 第三代伙伴组织计 划 （Third Generation Partnership Projects, 简称 3GPP )推出高级长期演进 ( Long-Term Evolution advance , 简称 LTE- Advanced )标准。 LTE- Advanced 对于长期演进 ( Long-Term Evolution, 简称 LTE ) 的演进保留了 LTE的核 心， 并在此基础上采用了一系列技术对频域、 空域进行扩充， 以达到提高 频谱利用率、 增加***容量等目的。
无线中继（ Wireless Relay )技术即 LTE-Advanced中的技术之一， 旨在 扩展小区的覆盖范围、 减少通信中的死角地区、 平衡负载、 转移热点地区 的业务和节省用户设备 ( User Equipment, 简称 UE ) 的发射功率。 如图 1 所示， RN对接入其小区的 UE提供与普通 eNB类似的功能和服务， 又通过 无线接口以类似于普通 UE的方式接入一个服务于它的 eNB,服务于 RN的 eNB称为 Donor eNB , 简称 DeNB。
根据中继节点是拥有自己的独立小区， 还是作为 DeNB下小区的一部 分， 分别定义了 Typel Relay和 Type2 Relay。 Typel Relay是指 RN能够创 建属于自己的独立小区， 这些小区拥有自己的物理小区标识（ Physical Cell
ID, 简称 PCI )。 RN在自己的小区内像基站一样工作， 如发送参考信号， 对 UE进行调度等。 Type2 Relay则没有自己独立的小区和 PCI, 只是辅助
DeNB进行数据传输。 除了 Typel Relay外， 标准中还定义了 "Typela" 和 "Type lb" Relay, 在小区建立方面它们与 Typel Relay类似， 都有自己的独 立的小区， 也独立进行控制信号的收发和调度。
从架构上来说，在控制面 RN与 DeNB建立唯一的 S1连接，并将 DeNB 视为唯一的移动性管理实体（ Mobility Management Entity , 简称 ΜΜΕ ) , 所 有与 UE相关的 SI信令都将通过该 S1连接发往 DeNB, DeNB将这些 SI 信令在自己与 MME的 S1连接上发往其真正的 MME 目的地。 同样， RN 也只与 DeNB建立唯一的 X2连接， RN与其他 eNB之间的 X2信令都必须 通过 DeNB转发。
需要注意的是， RN的操作维护管理***（ Operation and Maintenance, 简称 OAM ) 与 DeNB的 OAM无法通信（如两者属于不同的运营商）， 从 而使得 RN的 0AM为其分配的小区参数，如演进型陆地无线接入网的小区 全球标识（ E-UTRAN Cell Global Identifier, 简称 ECGI )与 DeNB所辖小区 的 ECGI可能沖突， 即丧失了 ECGI的唯一性， 所以 RN所辖小区的小区参 数由 DeNB分配， 而不是由 RN的 0AM分配。 因此在 DeNB为 RN分配小 区参数之前， DeNB需要知道 RN所辖小区的数目。 发明内容
有鉴于此， 本发明的主要目的在于提供一种中继节点小区参数的配置 方法及装置， 用于解决由于 DeNB不知道 RN的小区数目无法合理的配置 小区参数的技术问题。
为达到上述目的， 本发明的技术方案是这样实现的：
一种配置中继节点小区参数的方法， 该方法包括：
中继节点发送携带自身服务小区的小区数目的控制信令给宿主基站； 所述宿主基站根据所述控制信令中所包含的小区数目为中继节点配置 服务小区的小区参数。
进一步地， 所述宿主基站为中继节点配置其服务小区的小区参数包括 ECGI和 PCI。
进一步地， 所述控制信令包括以下至少之一： RRC信令、 S1信令、 X2 信令。
所述 RRC信令包括以下至少之一： RRC连接建立请求消息、 RRC连 接建立完成消息、 RRC连接重建立请求消息、 RRC连接重建立完成消息、 RRC连接重配置完成消息；

进一步地， 所述中继节点发送携带自身服务小区的小区数目的控制信 令给宿主基站具体为：
所述中继节点在与所述宿主基站建立 RRC连接、 或重建立 RRC连接、 或进行 RRC连接重配置、 或建立 S1连接之前， 发送携带自身服务小区的 小区数目的控制信令给所述宿主基站； 及
所述中继节点在与所述宿主基站已有 RRC连接、 或 S1 连接、 或 X2 连接， 且其服务小区的小区数目有增加时， 发送携带自身服务小区的小区 数目的控制信令给所述宿主基站。
基于本发明所述方法， 本发明还提出一种配置中继节点小区参数的装 置， 包括中继节点和宿主基站，
所述中继节点还用于向所述宿主基站发送携带自身服务小区的小区数 目的控制信令； 所述宿主基站还用于根据所述控制信令中所包含的小区数 目为所述中继节点配置服务 d、区的小区参数。
所述中继节点在与所述宿主基站建立 RRC连接、 或重建立 RRC连接、 或进行 RRC连接重配置、 或建立 S1连接之前， 发送携带自身服务小区的 小区数目的控制信令给所述宿主基站； 及
所述中继节点还用于在与所述宿主基站已有 RRC连接、 或 S1连接、 或 X2连接， 且其服务小区的小区数目有增加时，发送携带自身服务小区的 小区数目的控制信令给所述宿主基站。
本发明由 RN通过控制信令向 DeNB发送 RN所辖小区的小区数目，从 而使 DeNB能够更合理的配置 RN小区的参数，解决了 DeNB无法根据 RN 小区数目合理分配资源的问题， 避免 ECGI、 PCI等资源的沖突。 附图说明

如果 RN在与 DeNB建立 S1连接之前， 已经获知自身服务小区的小区 数目 （可能是预配置的， 或者是 RN的 OAM为其分配的）， 则 RN可以在 S1 连接建立的过程中向 DeNB发送一条包含其服务小区的小区数目的 S1 消息，从而将自身所辖小区的小区数目上报给 DeNB,使得 DeNB可以更合 理的配置 RN小区参数。
步驟如图 5所示：
步驟 501 : 在 RN与 DeNB的 S1连接建立的过程中 , RN通过向 DeNB 发送一条包含其服务小区的小区数目的 S 1消息来上报自身所辖小区的小区 数目。 所述 SI消息可以是 SlSetupRequest消息。
步驟 502: DeNB在成功接收携带所述小区数目的 SI消息后， 根据所 述小区数目合理地为 RN的服务小区配置 ECGI与 PCI: 如果当前的环境和 DeNB所具有的可用资源允许 RN建立其所能够支持的小区数目，则为其分 配相应所述小区数目的小区参数； 否则， 分配的小区参数可能少于所述小 区数目。 DeNB对 RN回复的消息可以是 S1建立响应 （ SlSetupResponse ) 消息 或 RRCConnectionRNReconfiguration消息。 实施例五
如果 RN与 DeNB间已有 S1连接，若其服务小区的小区数目有所增加， 则 RN可以向 DeNB发送一条携带服务小区的小区数目的 S1消息， 从而将 自身所辖小区的小区数目上报给 DeNB , 使得 DeNB可以更合理的配置 RN 小区参数。
步驟如图 6所示：
步驟 601 : RN的服务小区的小区数目发生改变后， 它可以向 DeNB发 送一条携带其服务 d、区的小区数目的 S 1消息以上报自身当前所辖小区的 d、 区数目， 这个数目可以是小区增加的数值， 也可以是更新后的完整数目。
所述 S1消息可以是 eNB CONFIGURATION UPDATE消息。
步驟 602: DeNB在成功接收携带所述小区数目的 S1消息后， 根据所 述小区数目合理为 RN的服务小区配置 ECGI与 PCI: 如果当前的环境和 DeNB所具有的可用资源允许 RN建立其所能够支持的小区数目，则为其分 配相应所述小区数目的小区参数； 否则， 分配的小区参数可能少于所述小 区数目。
DeNB回复的消息可以是基站配置更新确认（eNB CONFIGURATION UPDATE ACKNOWLEDGE ) 消息或 RRCConnectionRNReconfiguration消 lr 实施例六
如果 RN与 DeNB间已有 X2连接，若其服务小区的小区数目有所增加， 则 RN可以向 DeNB发送一条携带服务小区的小区数目的 X2消息，从而将 自身所辖小区的小区数目上报给 DeNB , 使得 DeNB可以更合理的配置 RN 小区参数。
步驟如图 7所示：
步驟 701 : RN的服务小区的小区数目发生改变后， 它可以向 DeNB发 送一条携带其服务小区的小区数目的 X2 消息以上报自身当前所辖小区的 小区数目， 这个数目可以是小区增加的数值， 也可以是更新后的完整数目。
所述 X2消息可以是 eNB CONFIGURATION UPDATE消息。
步驟 702: DeNB在成功接收携带所述小区数目的 X2消息后， 根据所 述小区数目合理地为 RN的服务小区配置 ECGI与 PCI: 如果当前的环境和 DeNB所具有的可用资源允许 RN建立其所能够支持的小区数目，则为其分 配相应所述小区数目的小区参数； 否则， 分配的小区参数可能少于所述小 区数目。
DeNB 对 RN 回复的消息可以是基站配置更新确认 （ eNB CONFIGURATION UPDATE ACKNOWLEDGE ) 消 息 或 RRCConnectionRNReconfiguration消息。 当然， 本发明还可有其它多种实施例， 在不背离本发明精神及其实质 的情况下， 熟悉本领域的技术人员当可根据本发明作出各种相应的改变和 变形， 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。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。 工业实用性
本发明由 RN通过控制信令向 DeNB发送 RN所辖小区的小区数目，从 而使 DeNB能够更合理的配置 RN小区的参数，解决了 DeNB无法根据 RN 小区数目合理分配资源的问题， 避免 ECGI、 PCI等资源的沖突。
