Description

移动通信系统的上行宏分集方法与装置 技术领域
本发明涉及一种移动通信系统的上行宏分集方法, 尤其是一种移动通信 系统中用户设备在跨越小区进行软切换时对多个基站的信号进行上行宏分集 合并的方法。 背景技术
在移动通信系统中, 移动终端在跨越小区时通常要进行原小区和新小区 之间的信号连接切换, 以通用移动通信系统 ( Universal Mobi le Telecommunicat ions Sys tem,筒称 UMTS )为例,当用户设备 ( User Equipment , 筒称 UE )进行越区切换时, 为了保证无线链路的质量, 需要保持连续的信号 连接, 也就是说 UE在断开旧小区的连接前, 需要建立与新小区的连接, 从而 可以在切换的时候保持住信号连接, 这种切换方式被称为软切换。 在软切换 过程中, UE至少和两个参与切换的基站(Node B )通信, 为了改善 UE在越区 切换时信号质量, 而且保持切换过程中不会丢失数据, UE和通用移动系统地 面无线接入网 (UMTS Terrestrial Radio Access Network, 简称 UTRAN )分 别把来自多个基站的信号进行分集合并, 这种分集合并的技术被称为宏分集。 对于切换区在整个网络占较多比例的网络来说, 例如, WCDMA的切换区占整个 网络的 30%至 40%, 如何进行上行宏分集对网络十分重要。
现有技术提供了一种基于传统的 UMTS架构进行上行宏分集的技术方案, 如图 1 所示, 为现有技术中上行宏分集的一种应用结构示意图。 在这种应用 场景中, 参与 UE1切换的 Node B 2和 Node B 3归属于同一个无线网络控制 4 ( Radio Network Control ler, 简称 RNC ), 该 RNC4接收到来自两个 Node B的数据,根据 UE1以预定周期或者根据特定事件发送的测量报告选择来自两 个 Node B的信号链路中质量好的链路, 将该链路的信号向上传送给核心网设 备 5 (例如 GGSN/SGSN )。 如图 2所示, 为现有技术中上行宏分集的另一种应用结构示意图, 在这: 种应用场景中, 参与 UE1切换的 Node B 2和 Node B 3归属于不同的 RNC, 其 中 Node B 2归属于 RNC4, Node B 3归属于 RNC6 , 在接收 UE1数据的相关 RNC 中, 只有一个 RNC能够进行对数据进行宏分集合并, 并上传给核心网设备 5, 这个 RNC被定义为第一 RNC, 与第一 RNC相连的 Node B被定义为第一 Node B。 对于不进行宏分集合并的 RNC被定义为第二 RNC , 与第二 RNC相连的 Node B 被定义为第二 Node B。 在图 2中 RNC4为第一 RNC, RNC6为第二 RNC , RNC 6从 Node B 3接收数据并转发送给 RNC4 , 然后由 RNC4将 UE1发送的测量报告解 开, 确定哪一个链路的信号最好, 选择信号最好的链路将数据上传到核心网 设备 5。 在现有技术中, 只有第一 RNC才对测量报告执行解包操作, 其他的第 二 RNC只是简单的接收测量报告, 而不对测量报告进行分析。 测量报告是由 UE按照预定的周期或者用户触发的事件发送给各个 RNC , 在测量 4艮告中包含 有与 UE相关联的数据链路的链路质量参数, 例如误码率、 信噪比等。 这种技 术有一定的缺陷, 主要体现在各个第二 RNC都要将从 UE接收到的数据转发给 第一 RNC, 这样就极大地增加了第一 RNC与第二 RNC之间的通信量, 网络负载 非常繁重。 发明内容

具体实施方式
本发明的构思是: 由于 UE按预定周期或者根据用户事件向各个 RNC都发 送测量报告, 而对于每一个 RNC来说, 根据测量报告可以获知各个 RNC中哪 条数据链路的质量最好, 因此使每个 RNC都对测量报告进行解包, 每个 RNC 都能获得用户设备上传数据的全部链路的链路盾量, 然后将链路质量最好的 数据上传给核心网。 相比于现有技术中只有第一 RNC 才对测量艮告解包, 需 要其他的第二 RNC将数据转发给第一 RNC来说, 减少了软切换时上行宏分集 的数据传输量, 也减轻了网络负载。
图 3-5 是本移动通信系统的上行宏分集方法应用于传! ^移动通信网络架 构的实施例, 其中图 5为本发明上行宏分集的方法的一实施例的流程示意图, 在软切换过程中, 包括以下步骤:

步骤 102、 所述数个无线网络控制器对解包后的测量报告进行分析, 判断 用于执行上行宏分集操作的第一无线网络控制器所在的数据链路的链路质量 在所述各条数据链路中是否为最高, 是则执行步骤 103, 否则执行步骤 104;
步骤 103、所述第一无线网络控制器直接将从所在的数据链路接收的数据 上传给核心网设备, 然后结束操作;
步骤 104、链路盾量最高的数据链路中的第二无线网络控制器将从所在的 数据链 收的数据转发给所述第一无线网络控制器, 再由所述第一无线网 络控制器将所述第二无线网络控制器转发的数据上传给核心网设备。
在本实施例的步骤 103中,用于执行上行宏分集操作的第一无线网络控制 器 4所在的数据链路的链路质量在各条数据链路中最高时, 则如图 3所示, 由无线网络控制器 4 直接将从所在的数据链 收的数据上传给核心网设备 5。 而当第一无线网络控制器 4所在的数据链路的链路盾量不是最高时, 可以 采用图 4 所示的流程, 即由链路质量最高的数据链路中的第二无线网络控制 器 7将从所在的数据链路接收的数据转发给第一无线网络控制器 4 ,再由第一 无线网络控制器 4将第二无线网络控制器 7转发的数据上传给核心网设备 5。 在本实施例中, 也可以在第一无线网络控制器 4所在的数据链路的链路 质量不是最高时采用现有技术中的流程, 即在与用户设备相关联的无线网络 控制器中, 除了用于执行上行宏分集操作的第一无线网络控制器 4, 其他无线 网络控制器都将接收到的数据传输到第一无线网络控制器 4,再由第一无线网 络控制器 4将接收的数据进行宏分集合并,然后上传给核心网设备 5。同样的, 采用步骤 104时, 步骤 103也可以替换为现有技术的流程。
在扁平化的网络架构中,无线网络控制器的部分功能被^ t到基站中,基 于这种网络架构本发明提供了另一个实施例进行描述, 如图 6-8,在软切换过 程中, 包括以下步骤:
步骤 201、用户设备接入核心网的数条数据链路对应的基站接收到所述用 户设备发送的测量报告时, 均解包所述测量报告, 获得所述用户设备接入核 心网的数条数据链路的链路质量;
步骤 202、 数个基站对解包后的测量报告进行分析, 判断用于执行上行宏 分集操作的第一基站所在的数据链路的链路质量在各条数据链路中是否为最 高, 是则执行步骤 203, 否则执行步骤 204;
步骤 203、第一基站直接将从所在的数据链路接收的数据上传给核心网设 备, 并结束操作;
步骤 204、链路质量最高的数据链路中的第二基站将从所在的数据链路接 收的数据转发给所述第一基站, 再由所述第一基站将所述第二基站转发的数 据上传给核心网设备。
在本实施例的步骤 203中,用于执行上行宏分集操作的第一基站 8所在的 数据链路的链路盾量在各条数据链路中最高时, 则如图 6所示, 由第一基站 8 直接将从所在的数据链^收的数据上传给核心网设备 5。而当第一基站 8所 在的数据链路的链路质量不是最高时, 可以采用图 7 所示的流程, 即由链路 质量最高的数据链路中的第二基站 9将从所在的数据链路接收的数据转发给 第一基站 8, 再由第一基站 8将第二基站 9转发的数据上传给核心网设备 5。
在本实施例中, 也可以在第一基站 8所在的数据链路的链路质量不是最 高时采用现有技术中的流程, 即在与用户设备相关联的基站中, 除了用于执 行上行宏分集操作的第一基站 8,其他基站都将接收到的数据传输到第一基站 8,再由第一基站 8将接收的数据进行宏分集合并, 然后上传给核心网设备 5。 同样的, 采用步骤 204时, 步骤 203也可以替换为现有技术的流程。

数据上传模块 34,用于将用户数据接收模块 31接收的数据上传给核心网 设备。
另一方面, 当链路质量确定模块 33确定出不执行上行宏分集操作的第二 无线网络控制器或第二基站所在的数据链路的链路质量, 在所述各条数据链 路中最高时,通知数据上传模块 34; 数据上传模块 34接收到链路质量确定模 块 33发送的通知后, 将用户数据接收模块 31接收的数据传送给执行上行宏 分集操作的第一无线网络控制器或第一基站。 从上述描述可知, 用户数据接收模块 31可以用于直接接收用户设备发送 的用户数据, 还可以用于接收第二无线网络控制器或第二基站发送过来的用 户数据。 数据上传模块 34可以用于将用户数据接收模块 31接收的数据上传 给核心网设备, 还可以用于将用户数据接收模块 31接收的数据传送给执行上 行宏分集操作的第一无线网络控制器或第一基站。
根据本发明上述实施例提供的上行宏分集实现方法,本发明还提供一种移 动通信系统的上行宏分集实现装置实施例二, 其结构示意图如图 10所示, 除 了包括有用户数据接收模块 31、 测量报告接收处理模块 32、 链路质量确定模 块 33和数据上传模块 34外, 还可以包括:
第一数据交互模块 35 ,用于当链路质量确定模块 33确定出执行上行宏分 集操作的第一无线网络控制器或第一基站所在的数据链路的链路质量, 在所 述各条数据链路中不是最高时, 接收链路质量最高的数据链路中的第二无线 网络控制器或第二基站发送过来的用户数据, 传送给用户数据接收模块 31; 再由用户数据接收模块 31发送给数据上传模块 34, 由数据上传模块 34将用 户数据上传给核心网设备。
还可以包括: 第二数据交互模块 36;
当链路质量确定模块 33确定出不执行上行宏分集操作的第二无线网络控 制器或第二基站自身所在的数据链路的链路质量, 在所述各条数据链路中最 高时, 通知第二数据交互模块 36;
第二数据交互模块 36,用于将用户数据接收模块 31接收的数据传送给执 行上行宏分集操作的第一无线网络控制器或第一基站。
下面结合附图, 对图 10所示移动通信系统的上行宏分集实现装置的工作 原理及信令交互过程进行详细描述。
本发明提供的移动通信系统的上行宏分集实现装置设置于执行上行宏分 集操作的第一无线网络控制器或第一基站中, 以及设置于不执行上行宏分集 操作的第二无线网络控制器或第二基站中, 下面以设备于第一基站和第二基 站为例进行描述。 第一基站中的测量报告接收处理模块 32 接收用户设备发送的测量报告 后, 解包所述测量报告, 获得用户设备接入核心网的各条数据链路的链路质 量; 第一基站中的链路质量确定模块 33, 确定出第一基站所在的数据链路的 链路质量在所述各条数据链路中最高时,通知第一基站中的数据上传模块 34; 第一基站中的数据上传模块 34,将第一基站中的用户数据接收模块 31接收的 数据上传给核心网设备。 其中, 用户数据接收模块 31接收的数据是直接从用 户设备接收的。
如果第一基站中的链路质量确定模块 33确定出第一基站所在数据链路的 链路盾量在所述各条数据链路中不是最高时, 则网络中肯定存在一个第二基 站会判断出其所在数据链路的链路质量最高, 该第二基站中的第二数据交互 模块 36将本地用户数据接收模块 31接收的数据发送给第一基站中的第一数 据交互模块 35;
第一基站中的第一数据交互模块 35接收到数据后, 传送给第一基站中的 用户数据接收模块 31 ,再由第一基站中的用户数据接收模块 31传送给第一基 站中的数据上传模块 34,由第一基站中的数据上传模块 34将用户数据上传给 核心网设备。
由于本发明可以在用于执行上行宏分集操作的第一无线网络控制器或第 一基站的链路质量最好的时候, 直接将接收的数据上传给核心网, 因此不为 网络增加数据和信令的负载。 而当第一无线网络控制器或第一基站的链路质 量不是最好时, 只需链路质量最好的第二无线网络控制器或第二基站将数据 发送给第一无线网络控制器或第一基站, 与现有技术相比, 减少了无线网络 控制器之间或基站之间的数据传输, 也增加了系统容量。
最后应当说明的是:以上实施例仅用以说明本发明的技术方案而非对其 限制; 尽管参照较佳实施例对本发明进行了详细的说明, 所属领域的普通技 术人员应当理解: 依然可以对本发明的具体实施方式进行修改或者对部分技 术特征进行等同替换; 而不脱离本发明技术方案的精神, 其均应涵盖在本发 明请求保护的技术方案范围当中。
