Description

中继站通信的方法、 装置和系统 本申请要求于 2008 年 9 月 28 日提交中国专利局、 申请号为 200810168484.5, 发明名称为"中继站通信的方法、 装置和系统"的中国专利申 请的优先权, 在先申请文件的内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域, 尤其涉及中继站通信的方法、 装置和系统。
背景技术
在传统的蜂窝网络的小区中, 基站与用户设备 ( UE, equipment user )之 间的无线连接是直接的无线连接, 基站与用户设备之间的通信不经过第三者 实现。 在小区覆盖范围大、 基站负载高或者小区物理环境复杂时, 基站与用 户设备之间的通信质量往往不高, 为了解决这个问题,可以在基站与 UE之间 增加了一个或多个中继站(Relay ), 负责将基站与 UE之间的信号做一次或者 多次转发。 Relay的主要功能是对接收到的信号进行放大、 译码等处理, 然后 转发给通信对端, 以提高所述通信对端的信号接收性能。
在实现上述小区中继转发的过程中, 发明人发现现有技术中至少存在如 下问题: 现有技术的系统中, 增加了中继站后, 无法确定中继站的中继身份 标识。
发明内容

本发明实施例提供的小区中继控制的方法、 装置和系统, 中继站获取系 统为其分配的中继 ID,则中继站就可以根据获取的中继 ID与系统中的其它设 备进行通信, 基站就可以根据中继 ID对系统中新增的中继站进行有效管理, 提高系统的效率。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实 施例或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面 描述中的附图仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动性的前提下, 还可以根据这些附图获得其他的附图。
图 1为本发明中继站通信的方法的第一实施例流程图;
图 2为本发明中继站通信的方法的第二实施例流程图;
图 3为本发明系统实施例结构示意图;
图 4为本发明系统实施例中继站结构示意图;
图 5为本发明系统实施例基站结构示意图。
具体实施方式
下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而 不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作 出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
目前,在 LTE系统中的 Relay没有自己的身份标识, 中继 ID ( Relay ID ), 在本发明的具体实施方式中,基站需要与 Relay进行通信,为了完成通信过程, 系统为中继站分配中继 ID。在通信过程中,中继站通过接入过程获取中继 ID, 并进行通信。
如图 1所述, 为本发明实施例提供的中继站通信的方法, 包括:
S101 : 获取中继站的中继 ID;
S102: 根据所述中继 ID进行通信。
通过本具体实施方式提供的方案, 中继站获取系统为其分配的中继 ID, 则中继站就可以根据获取的中继 ID与系统中的其它设备进行通信, 基站就可 以根据中继 ID对系统中新增的中继站进行有效管理, 提高系统的效率。
为了保证本方法能够与现有技术兼容, 在本发明实施方式中, 中继站使 用现已存在的标识。 现在小区中已经应用的身份标识主要有两种: 小区身份 标识 Cell ID和用户设备身份标识 UE ID。 Cell ID不能用来作为 Relay ID, 因 为基站和中继站之间的通信应该与基站和用户终端 UE的通信过程保持一致, 这是为了对目前规范做尽可能小的改动, 这样, 对于基站来说, 中继站就是 一个特殊的 UE, 而不能看作是另外一个不同的 Cell。
因此, 在本发明具体实施方式中, 可以将在 LTE Release 8的版本中, 将 为用户设备身份标识中预留的字段中不用于 UE ID的字段分配给中继站作为 中继 ID。具体可以为基站在接收到新增的中继站发送的接入请求时, 从为 UE ID预留的字段中选择一个字段分配给该中继站, 作为中继 ID, 该预留的字段 可以为 FFF3 - FFFC。
中继站在接入网络时, 向基站发送接入请求消息, 基站接收到该接入请 求消息后, 返回接入应答消息, 该接入应答消息中, 包含为该中继站分配的 中继接入 ID, 用于该中继站进行接入。 同时, 该接入应答消息中还可以包含 用于该中继站在接入网络后进行正常通信的中继通信 ID。 将该预留的部分字 段分配作为中继站的中继接入 ID, 若有多个中继站, 则可以竟争使用分配的 中继接入 ID。 例如 , 将 FFF3作为中继接入 ID , 则 FFF3 - FFFC中的剩余几 个可以用作中继通信 ID, 即中继站正常通信时的 ID, 中继站接入成功后, 由 基站选择一个并分配给该中继站, 如果 FFF3分配成中继接入 ID , 则 FFF4 - FFFC可以用作中继通信 ID。 另外, 根据需要, 可以将一个中继通信 ID分配 给一个 Relay的集合。
在系统中新增中继站是为了解决基站与用户设备之间通信质量不高的问 题, 在基站与用户设备能够保证正常通信的情况下, 是不需要中继站的。 但 是, 现有小区中继转发的过程中, 中继站会将自己收到的信号全部转发给通 信对端, 并不考虑基站与用户设备之间的通信质量是否需要中继, 这会造成 中继站本身的工作量很大, 这对中继站的发射功率提出较高的要求, 要求中 继站能以较大的功率工作, 并会在相邻小区产生较大的干扰。 针对该问题, 如图 2所述, 本发明实施例提出一种中继站通信的方法, 包括:
S201、 中继站向基站发起接入请求消息。
S202、 基站接收来自中继站的接入请求消息。
S203、 基站向中继站返回接入应答消息, 所述接入应答消息中包含中继 通信 ID。
在实际应用中, 基站可以将用户设备身份标识中的预留字段的全部或者 一部分, 作为中继站接入身份标识和中继站转发身份标识的可选择字段, 但 具体分配给每一个中继站的中继站接入身份标识和中继站转发身份标识只能 各为一个。
现有中继转发的过程中, 中继站会将自己收到的信号全部转发给通信对 端, 并不考虑基站与用户设备之间的通信质量是否需要中继。 这主要是因为 现有中继站在小区中没有自己的身份标识, 所以现有基站无法对中继站进行 单独的操作控制造成的, 有鉴于此, 本步骤先由基站向中继站发送一个中继 通信 ID。
5204、 中继站接收基站返回的接入应答消息, 解出所述接入应答消息中 的中继通信 ID。
中继站获取中继通信 ID的过程可以为:
接收基站返回的接入应答消息;
如果所述接入应答消息中包含中继站接入 ID, 进一步解析接入应答消息 中的控制信令;
通过解析的控制信令进一步查找接入应答消息中的应答数据, 并从所述 应答数据中查询得到中继通信 ID。
5205、 基站向中继站发送控制信息, 所述控制信息指定了中继站的中继 转发状态, 并携带有中继站的中继通信 ID。
基站向中继站发送控制信息的过程具体为: 基站向一组中继站以广播的 方式发送控制信息。 这种技术方案主要是基于一组中继站共享一个中继站转 发身份标识的前提。
所述控制信息包含一个针对中继站的控制策略, 包括需要中继站转发哪 些信号, 以什么形式转发(发射的功率、 频带等参数)等内容。 该控制策略 以控制信息的形式发送给中继站, 所述控制信息还携带有实现该控制策略的 中继站的中继通信 ID。
5206、 中继站接收来自基站的控制信息, 如果所述控制信息携带的中继 通信 ID与接入应答消息中的中继通信 ID—致, 按照所述控制信息指定的状 态进行中继转发。
通过所述中继通信 ID, 中继站辨别出基站发给自己的控制信息, 按照所 述控制信息指定的状态进行中继转发, 从而实现基站对中继站的控制。
通过本实施例的技术方案, 为中继站分配中继通信 ID, 基站通过所述中 继通信 ID对中继站进行控制, 进而使中继站只转发基站与用户设备之间通信 质量不高的信号, 减轻了中继站本身的工作量, 降低了中继站的功率, 最终 降低了由中继站带来的小区间干扰。

操作单元 12 , 用于根据所述获取单元 11获取的所述中继 ID进行通信。 该中继 ID可以为从 UE ID预留分配的部分字段中选择, 该为 UD ID预 留的部分字段可以为 FFF3 - FFFC
进一步, 该中继站设备 1还包括接收单元 13 , 用于获取基站发送的接入 应答消息, 所述接入应答消息包含所述中继 ID。
接收单元 13还用于接收基站发送的控制信息;
所述操作单元 12包括操作子单元 14 , 所述操作子单元 14用于根据所述 获取单元获取的中继 ID,按照所述接收单元 13接收的控制信息指定的状态进 行中继通信。
如图 5所示, 为本发明基站设备 2的实施方式结构示意图, 包括: 接收单元 21 , 用于接收中继站发送的接入请求消息;
分配单元 22, 用于为中继站分配中继 ID。 可以将为用户设备身份标识中 预留的字段中不用于 UE ID的字段分配给中继站作为中继 ID。 具体可以为基 站在接收到新增的中继站发送的接入请求时, 从为 UE ID预留分配的部分字 段中选择一个字段分配给该中继站, 作为中继 ID, 该为 UD ID预留的部分字 段可以为 FFF3 - FFFC。
发送单元 23 , 用于将分配单元 22为中继站分配的中继 ID包含在接入应 答消息中发送给中继站。
进一步, 为了对中继站进行控制, 该基站的发送单元 23还用于发送控制 信息。 所述控制信息指定了中继站的中继转发状态, 并携带有中继站的中继 通信 ID,使得中继站在控制信息携带的中继通信 ID与接入应答消息中的中继 通信 ID—致, 按照所述控制信息指定的状态进行中继转发。
