Description

一种压缩模式的控制方法及系统 技术领域
本发明涉及无线通信技术, 尤其涉及一种压缩模式的控制方法及系统。 背景技术
随着通信无线网络技术的不断演进, 从第二代的全球移动系统(Global System Mobile , GSM ) 系统到第三代的宽带码分多址 ( Wideband Code Division Multiple Access, WCDMA ) 系统, 再到第三代的增强型全球无线 接入网络 ( Enhanced Universal Radio Access, E-UTRA ) 系统, 运营商的网 络部署也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系统主要用于承载分组域业务和会话类、 视频类业务, 第三代的 E-UTRAN系统重点在于承载超高速的分组域业务。
因此,针对现有的网络部署,第二代的 GSM系统和第三代的 WCDMA 系统间的移动性是非常重要的, 并且, 在不久的将来, 第三代的 E-UTRA 系统的移动管理, 如切换到 E-UTRA系统热点区域, 也将变得重要起来。
上述的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, 当釆用压缩模 式时, 终端不需要配置双接收机就可测量非服务的载频以及其他系统的载 频, 当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系统覆盖的地区时, 只能够釆用压缩模式进行系统间的测量。 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。 总而言之, 在压缩模式下, 终端可以测量另外一个非服务载频而不丟失在 服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, 数据传输在时域上将 被压缩而产生出一个传输间隙。 终端的接收机可利用这段传输间隙调谐到 另外一个载频上测量。 传输间隙一般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, 仅能够用于 一种传输间隙样式序列测量用途, 也就是频分双工测量、 时分双工测量、
GSM载波接收信号强度指示 (Received Signal Strength Indication )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、 E-UTRA测量等测量用途中的一种。
图 1为一传输间隙样式序列的结构示意图, 如图 1所示, 该传输间隙 样式序列包含两种交替的传输间隙样式, 分别为传输间隙样式 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, CFN )、 传输间隙样 式序列的重复次数等, 这些参数都是依据传输间隙样式序列测量用途来确 定的。
考虑到加快切换过程以增加切换的可靠性, 尤其是在无线信号质量快 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。 为了提高 系统容量和用户吞吐量, 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。 现有技术中, 一般由终端控制压缩模式的启动或停止, 例 如, 终端判断当前服务小区的无线信号质量不好, 可能需要准备切换到载 频间 /系统间的邻区, 则启动压缩模式; 终端判断当前服务小区的无线信号 质量转好或者已经得到测量结果, 则停止压缩模式。 对应的, 当终端决定 启动 /停止压缩模式时, 会将启动 /停止的传输间隙样式序列告知节点 B。
但是, 现有压缩模式的控制方法存在以下问题: 当大量终端出现在一个小区时, 该小区可用资源可能会不足以保证所 有终端的所有业务的服务质量, 从而导致拥塞或者过载, 一种应对拥塞或 者过载小区的低成本方法是把业务均衡到较低负荷的邻区 (即负荷均衡机 制), 而由于当前服务小区的负荷过高需要进行频间切换或者系统间切换 时, 无线信号并没有问题, 终端在当前服务小区中测量的无线信号质量通 常都是较好的, 如果将现有控制压缩模式的方法应用于负荷均衡触发的频 间切换或者系统间切换, 则达不到尽快切换的效果, 从而无法及时降低当 前服务小区负荷, 容易导致当前服务小区崩溃, 影响到当前服务小区中终 端业务的正常运行。 另外还有一种场景: 由于运营商对于多无线系统部署 网络的情况, 会对不同系统或者不同频点有业务部署的倾向性, 比如第二 代无线移动通信系统吸收话音业务, 第三代无线移动通信系统吸收分组域 业务; 那么当终端从非期望的系统或者频率层呼入业务后, 则无线网络控 制器也会对该终端执行系统间切换或者频间切换来达到业务部署的目的; 但为了在做系统间切换或者频间切换时尽可能减小对业务的影响, 现有的 启动压缩模式的策略将达不到尽快切换的效果, 从而会影响业务的稳定性 和系统容量。
同时, 对于上述由于负荷均衡或者业务均衡机制触发频间切换或者系 统间切换的情况, 釆用节点 B替代终端来控制压缩模式的做法也是不可行 的, 这是因为, 一旦当前服务小区的邻区是归属于其他节点 B的, 节点 B 无法获得或者知情其他节点 B下的小区的负荷情况, 从而无法准确控制压 缩模式的启动或停止, 节点 B也无法获知不同系统或者不同频率层之间的 业务部署策略, 从而也无法准备控制压缩模式的启动或者停止。 发明内容
有鉴于此, 本发明的主要目的在于提供一种压缩模式的控制方法及系 统, 能够应用于由于负荷均衡或业务均衡触发频间切换或者系统间切换的 场景下, 从而及时降低当前服务小区负荷, 保障小区中终端业务的稳定性。 为达到上述目的, 本发明的技术方案是这样实现的:
