Description
宏分集状态下压缩模式的控制方法及系统 技术领域 本发明涉及通信领域, 具体而言, 涉及一种宏分集状态下压缩模式的控 制方法及系统。 背景技术 随着无线通信网络技术的不断演进, 从第二代的全球移动系统 ( Global System for Mobile Communications, 简称为 GSM )到第三代的宽带码分多址 ( Wideband Code Division Multiple Access , 简称为 WCDMA ) 系统, 再到第 三代的长期演进(Long Term Evolution, 简称为 LTE ) 系统, 运营商的网络 部署必然依据用户的需求, 存在多种制式系统并存的情况。 目前, 运营商通 常的无线网络功能定位为: 第二代的 GSM 系统主要用于承载话音, 第三代 的 WCDMA系统主要用于 载分组业务和会话、视频类业务, 第三代的 LTE 系统重点在于承载超高速的分组业务。 针对现有的网络部署, 第二代的 GSM系统和第三代的 WCDMA系统之 间的系统间移动性非常重要; 并且, 在不久的将来, 第三代 LTE系统的移动 管理, 如切换到 LTE系统热点区域, 也将变得非常重要。 上述这些系统间移动管理导致的切换过程均需要在事先的切换准备阶段 对目标系统以及目标载频进行测量, 以便准确进行切换决策。 压缩模式在载频间和系统间测量中起到很重要的作用。釆用压缩模式时, 终端不需要配置双接收机就可以测量非服务载频以及其他系统的载频。 对于 只配置了一个接收机的终端, 从第三代 WCDMA 系统移动到只有第二代 GSM系统覆盖的区域时, 只能够釆用压缩模式来进行系统间测量。 同样, 压 缩模式也可用于终端进出第三代 WCDMA系统的多载频覆盖区域。在压缩模 式下, 终端可以测量另外一个非月艮务载频, 同时又不丢失在月艮务载频上传输 的任何数据。 压缩模式定义为一种传输模式, 通过这种方式, 数据在时域上传输时将 被压缩而产生一个传输间隙, 终端的接收机利用这段传输间隙调谐到另一个 载频上进行测量。
传输间隙由 "传输间隙样式序列" 来描述确定。 每一套 "传输间隙样式 序列" 由 "传输间隙样式序列标识" 来唯一识别, 且仅能够用于一种 "传输 间隙样式序列测量用途", 该测量用途可以是 "频分双工测量"、 "时分双工测 量"、 "GSM载波接收信号强度指示 ( Received Signal Strength Indication, 简 称为 RSSI )测量"、 "GSM基站识别色码初始识别,,、 "GSM基站识别色码识 别再次确认"、 "多载频测量" 和 "增强型全球无线接入网络 ( Enhanced Universal Radio Access, 简称为 E-UTRA ) 测量" 等各个测量中的一种测量 用途。 图 1是根据相关技术的传输间隙样式序列的示意图, 如图 1所示, 每一 套 "传输间隙样式序列 " 包含 2种交替的传输间隙样式: "传输间隙样式 1" 和 "传输间隙样式 2"。 每种 "传输间隙样式" 在一个 "传输间隙样式长度" 内提供一个或者两个传输间隙。 此外, 每一套 "传输间隙样式序列,, 还包括 指示启动 /停止压缩模式时间的传输间隙连接帧号 ( Connection Frame Number, 简称为 CFN ), 传输间隙样式序列的重复次数等等。 这些参数都是 依据"传输间隙样式序列测量用途"来确定的。 加快切换过程能够提高切换的可靠性, 尤其在无线信号质量快速恶化的 区域, 通过加快切换的过程可以降低用户掉话的风险。 压缩模式启动的时间 越晚越好, 压缩模式持续的时间越短越好, 以此来提高系统容量和用户吞吐 量。 因此, 可以由压缩模式的执行者, 即, 终端和基站(节点 B ( Node B ) ), 来控制压缩模式的启动 /停止。 当终端控制压缩模式的启动 /停止时, 如果终 端确定当前服务小区的无线信号质量不好,可能需要切换到异载频 /异系统的 邻区, 则启动压缩模式; 如果终端确定当前月艮务小区的无线信号质量转好或 者已经得到测量结果, 则停止压缩模式。 当终端决定启动 /停止时, 终端将启 动 /停止的 "传输间隙样式序列,, 告知节点 当基站 (节点 B )控制压缩模 式的启动 /停止时, 基站 (节点 B ) 直接将启动 /停止的命令通知终端。 终端或基站(节点 B )控制压缩模式的启动 /停止具有快速、 时间短的优 点, 但如果终端处于宏分集状态, 则会存在问题。 图 2和图 3分别示出了终 端的两种应用场景, 在图 2 所示的场景中, 终端与无线网络控制 (Radio Network Control,简称为 RNC ) 1下节点 B1和节点 B2同时建立有无线链路; 在图 3所示的场景中,终端与 RNC1下节点 B1和 RNC2下节点 B2同时建立 有无线链路。 发明人发现, 在这两种场景下, 压缩模式的启动 /停止是由终端 或者节点 B1 决定的, 节点 B2 无法获知压缩模式的执行状态, 因此, 节点
B2不能和终端同步执行压缩模式。 发明内容 本发明的主要目的在于提供一种宏分集状态下压缩模式的控制方案, 以 解决相关技术中终端在宏分集状态下与终端连接的多个基站中的部分基站不 能和终端同步执行压缩模式的问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种宏分集状态下 压缩模式的控制方法, 该方法包括: 终端和第一节点 B协商确定压缩模式状 态, 其中, 第一节点 B与终端相连; 终端向服务无线网络控制器上报压缩模 式状态; 服务无线网络控制器将压缩模式控制信息发送给除第一节点 B以外 的与终端相连的节点 B , 其中, 压缩模式控制信息包括压缩模式状态; 节点 B使用压缩模式控制信息与终端同步执行压缩模操作。 进一步地,服务无线网络控制器将压缩模式控制信息发送给节点 B包括: 月艮务无线网络控制器确定节点 B不直接和月艮务无线网络控制器相连; 月艮务无 线网络控制器将压缩模式控制信息发送给漂移无线网络控制器; 漂移无线网 络控制器将压缩模式控制信息发送给其下属的节点 B。 进一步地,服务无线网络控制器将压缩模式控制信息发送给节点 B包括: 月艮务无线网络控制器确定节点 B直接和月艮务无线网络控制器相连; 月艮务无线 网络控制器直接将压缩模式控制信息发送给节点 B。 进一步地, 服务无线网络控制器直接将压缩模式控制信息发送给节点 B 包括: 服务无线网络控制器确定节点 B多于一个; 服务无线网络控制器直接 将压缩模式控制信息发送给所有节点 B。 进一步地,压缩模式控制信息包括以下至少之一: 指示压缩模式的标识、 压缩模式的启动 /停止时间、 传输间隙样式序列 TGPS的重复次数。 为了实现上述目的, 根据本发明的另一方面, 提供了一种宏分集状态下 压缩模式的控制系统, 该系统包括: 服务无线网络控制器和节点 B, 服务无 线控制器包括: 接收模块, 用于在终端和第一节点 B协商确定压缩模式状态 之后, 接收终端上报的压缩模式状态, 其中, 第一节点 B与终端相连; 发送 模块, 用于将压缩模式控制信息发送给除第一节点 B以外的与终端相连的节 点 B, 其中, 压缩模式控制信息包括压缩模式状态; 节点 B用于使用压缩模
