一种控制系统间测量和频间测量的方法
技术领域
本发明涉及一种在宽带码分多址 (Wideband Code Division Multiple
Access) 系统 (以下简称 WCDMA) 中控制系统间和频间测量的方法。
背景技术
WCDMA 系统可以提供非常丰富的业务类型和高速率数据的接入, 同时支持与 GSM系统的双向切换, WCDMA系统的优异性能吸引了很多 GSM高端用户。但是, WCDMA网络却很难在短时间内建设成为象 GSM 网络那样完整的覆盖, 这样就必须利用向 GSM 系统的切换以弥补 WCDMA系统的覆盖盲区。
系统间切换一般需要通过打开压縮模式对应的系统间测量才能进行, 开启压缩模式会对系统带来额外的负荷。 尽可能地减少压缩模式的开启 时间对降低 WCDMA系统的负荷是有益的,尤其是对于 WCDMA系统覆 盖的边缘的小区。 但是压缩模式启动的过晚又会减少系统间测量的时间, 增加了掉话的可能。 这样, 如何在保证用户业务服务质量的同时, 适时 地进行 WCDMA系统的系统间测量就成为一个需要解决的问题。
目前国内外巳有一些 WCDMA系统的系统间测量和切换的方法。 如 申请号为 01144933.0的中国专利 "一种系统间切换方法"是通过测量当 前 WCDMA小区导频信道的质量来决定开启压缩模式和系统间测量的时 机。 其中导频信道的好坏是通过一个绝对门限确定的。 但是, 通过导频 信道的好坏来确定专用信道的好坏存在一定的片面性, 首先 WCDMA系 统丰富的业务决定了不可能用单一的一个导频覆盖来精确描述不同业务 的覆盖, 其次, 即使对于单一业务, 当导频规划不合理时, 导频的覆盖 和业务的覆盖也不能保证一致。
公开号为 20020187784 的美国专利 "Method of WCDMA coverage based handover triggering"是描述基于覆盖切换的一种方法, 该专利的思 想是通过对上下行无线链路的发射功率和上行物理信道信干比 (Signal Interference Rate简称 SIR),来触发 WCDMA系统向 GSM系统切换的。 但是,无论是发射功率还是物理信道 SIR, 都不能直接反映当前专用链路 的质量, 存在一定的误判几率。
另外, UE (移动终端) 在专用状态下进行频间切换时, 所进行的频 间测量也需要打开压缩模式才能进行。 因此, 也需要提供一种方法, 可 以适时地触发 WCDMA系统的频间测量,在保证用户的服务质量的同时, 能够减少压缩模式的开启时间, 降低系统的负荷。 发明内容
本发明要解决的技术问题是提出一种控制系统间测量的方法,能够确 实保证用户的服务质量, 同时尽可能地减少压缩模式的开启时间。
为了解决上述技术问题, 本发明提供了一种控制系统间测量的方法, 包括以下步骤:
( a) 在宽带码分多址系统的网络侧设置基于上行和下行链路传输信 道误块率 (BLER) 的打开系统间测 S的判决规则;
( b )用户在该网络中建立呼叫进入专用状态后, 网络侧打开对用户 业务相关的下行和上行链路传输信道误块率的测量, 并接收测量结果;
(c) 网络侧根据用户的所述上行和下行链路传输信道误块率的测量 结果, 依照所述判决规则判断用户当前的业务质量是否已不能满足要求, 如果是, 执行下一步, 否则, 执行步骤 (e) ;
( d)网络侧在该用户当前系统间测量未打开时,打开其系统间测量, 结束;
(e)网络侧在该用户当前系统间测量未关闭时,关闭其系统间测量, 结束。
进一步地,上述控制系统间测量的方法还可具有以下特点:所述网络 侧设置的判决规则中, 为各个上行和下行链路传输信道分别设置了一个 打开系统间测量的误块率门限, 如果测量值大于该门限, 则判决该传输 信道的当前业务质量已不能满足要求。
进一步地,上述控制系统间测量的方法还可具有以下特点:所述网络 侧设置的判决规则中, 针对不同的业务, 分别设置其相关上行和下行链 路传输信道的误块率门限。
进一步地,上述控制系统间测量的方法还可具有以下特点:所述判决 规则中, 在用户业务相关的下行和上行链路传输信道误块率的测量结果 中只要有一个大于其对应的门限时, 就判决该用户当前的业务质量已不 能满足要求。
进一步地,上述控制系统间测量的方法还可具有以下特点:所述步骤 ( c ) 网络侧是在收到所述上行或者下行链路传输信道误块率的测量结果 后, 马上对用户当前的业务质量是否满足要求进行判决。 这样, 可以及 时对业务质量的变化做出反应, 防止发生掉话。
进一步地,上述控制系统间测量的方法还可具有以下特点:所述打开 测量、 接收测量结果以及判决的过程是由无线网络控制器内的控制模块 完成的, 而对用户业务相关的上行链路传输信道误块率的测量是由无线 网络控制器内的测量模块完成。
进一步地,上述控制系统间测量的方法还可具有以下特点:所述网络 侧对用户业务相关的下行链路传输信道误块率的测量由以下步骤完成: 无线网络控制器向用户的移动终端发送测量控制消息, 要求其测量下行 链路传输信道的误块率, 并周期上报测量结果; 所述移动终端按要求进 行测量, 并定时向无线网络控制器上报测量结果。
本发明要解决的另一技术问题是提出一种控制频间测量的方法,能够 确实保证用户的服务质量, 同时尽可能地减少压缩模式的开启时间。
为了解决上述技术问题, 本发明还提供了一种控制频间测量的方法, 包括以下步骤: (i)在宽带码分多址系统的网络侧设置基于上行和下行链路传输信 道误块率的打开频间测量的判决规则;
(j )用户在该网络中建立呼叫进入专用状态后, 网络侧打开对用户 业务相关的下行和上行链路传输信道误块率的测量, 并接收测量结果; (k) 网络侧根据用户的所述上行和下行链路传输信道误块率的测量 结果, 依照所述判决规则判断用户当前的业务质量是否已不能满足要求, 如果是, 执行下一步, 否则, 执行步骤 (m) ;
(1) 网络侧在该用户当前频间测量未打开时, 打开其频间测量, 结 束;
(m) 网络侧在该用户当前频间测量未关闭时, 关闭其频间测量, 结 束。
进一步地,上述控制频间测量的方法还可具有以下特点:所述网络侧 设置的判决规则中, 为各个上行和下行链路传输信道分别设置了一个打 开频间测量的误块率门限, 如果测量值大于该门限, 则判决该传输信道 的当前业务质量已不能满足要求。
进一步地,上述控制频间测量的方法还可具有以下特点:所述网络侧 设置的判决规则中, 针对不同的业务, 分别设置其相关上行和下行链路 传输信道的误块率门限。
进一步地,上述控制频间测量的方法还可具有以下特点:所述判决规 则中, 在用户业务相关的下行和上行链路传输信道误块率的测量结果中 只要有一个大于其对应的门限时, 就判决该用户当前的业务质量已不能 满足要求。
进一步地,上述控制频间测量的方法还可具有以下特点:所述步骤 (k) 网络侧是在收到所述上行或者下行链路传输信道误块率的测量结果后, 马上对用户当前的业务质量是否满足要求进行判决。
进一步地,上述控制频间测量的方法还可具有以下特点:所述打开测 量、 接收测量结果以及判决的过程是由无线网络控制器内的控制模块完 成的, 而对用户业务相关的上行链路传输信道误块率的测量是由无线网 络控制器内的测量模块完成。
进一步地,上述控制频间测量的方法还可具有以下特点:所述网络侧 对用户业务相关的下行链路传输信道误块率的测量由以下步骤完成: 无 线网络控制器向用户的移动终端发送测量控制消息, 要求其测量下行链 路传输信道的误块率, 并周期上报测量结果; 所述移动终端按要求进行 测量, 并定时向无线网络控制器上报测量结果。
由上可知, 本发明利用直接反映 UE业务质量的上下行业务信道 BLER作为判决依据, 可达到精准的判决效果。 另外, 本发明还可以针对 不同的业务设置不同的 BLER 门限, 进而实现不同业务启动系统间测量 的时机不同。 因此, 本发明方法使得系统间测量打开的时机最精确, 用 户的业务质量能够得到最确实的保证, 同时也减少了压缩模式的开启时 间, 降低了 WCDMA系统的负荷。 对于频间测量, 本发明方法也具有同 样的效果。 附图概述
图 1是本发明实施例方法的流程图。
图 2是本发明实施例测量获得 UE下行传输信道 BLER的信令流程。
本发明的最佳实施方式
最直接反映用户业务质量的参数是上下行传输信道的误块率 (Block Error Rate简称 BLER) 。 通常, 在 WCDMA系统专用信道上下行外环和 内环功控的作用下, 上下行传输信道的 BLER保持在预设的目标值。 当 用户移动出 WCDMA系统, 功控不能正常起作用时, 用户的 BLER就会 变差, 根据 BLER的变化情况, 就可以精确地确定是否需要打开系统间
进一步地,不同业务对应不同的传输信道,不同的传输信道用户业务 质量的变化并不是一致的。因此,通过对到 UE的下行链路传输信道 BLER 的测量和对到基站的上行链路传输信道 BLER的测量, 对每个传输信道 可以采用不同的判决准则, 就可以直接客观地确定上下行专用信道的质 量, 进而准确地启动系统间测量, 最终触发系统间切换。
下面结合附图对本发明技术方案的实施作进一步的详细描述,如图 1 所示, 本实施例方法包括以下步骤:
步骤 200,在宽带码分多址系统的网络侧为各个上行和下行链路传输 信道分别设置打开系统间测量的 BLER门限, 超过该门限则视为信号质 量不能满足要求; ·
本实施例还针对不同的业务,分别设置其相关的上行和下行链路传输 信道的 BLER门限, 以取得各种业务的打开系统间测量的合适时机。 例 如, 对于语音业务可以设为 1%左右, 对于交互式业务 (PS业务) , 如 FTP下载, 可设为 5%〜10%。
步骤 201, 用户在 WCDMA网络中建立呼叫, 进入专用状态; 步骤 202, 网络侧打开 UE的质量测量, 测量过程的消息流程如图 2 所示, RNC先向 UE发送测量控制消息,要求 UE周期测量下行链路传输 信道的 BLER, UE进行测量并定时向 RNC上报测量结果;
步骤 203, 网络侧打开对基站上行链路传输信道 BLER的测量, 该测 量是在网络侧设备内部进行的, 本实施例是由 RNC内的测量模块完成, 不需要经过标准接口;
需要说明的是,步骤 202和 203中打开上、下行链路传输信道 BLER 的测量的先后可以做不同设置。
步骤 204, 网络侧进入等待状态;
步骤 205, 网络侧的控制模块(一般设在 RNC内) 收到 UE上报的 质量报告消息后, 提取其中的各个下行链路传输信道的 BLER信息; 或 者,该控制模块收到设备内部测量模块上报的用户的上行传输信道 BLER 步骤 206,控制模块判决用户当前各个传输信道上行和下行 BLER是 否有至少一个大于自己的 BLER门限, 如果是, 说明该用户有些业务质 量已经不满足设定的目标质量, 用户已经移动到了 WCDMA网络的覆盖 边缘, 需要尽快打开系统间测量,执行步骤 209; 如果小于等于 BLER门 限, 说明当前业务质量良好, 没必要进行系统间测量, 执行步骤 207; 步骤 207, 判断该用户当前系统间测量是否打开, 如果已经打开, 执 行步骤 208, 否则, 返回步骤 204;
步骤 208, 关闭系统间测量, 返回步骤 204;
步骤 209, 判决该用户当前系统间测量是否关闭, 如果关闭, 执行步 骤 210, 否则执行步骤 204;
步骤 210, 打开系统间测量, 返回步骤 204。
通过对各传输信道的 BLER门限的合理设置,可以保证 UE有足够的 测量时间。 另外, 上述判决过程中, 只要有一个传输信道的质量变坏就 启动系统间测量, 这是因为各传输信道使用的是同一个物理信道, 任何 一个传输信道的质量不好也就意味着物理信道的功控失去了作用, 其他 传输信道的质量也会很快变差。 所以这样处理可以用最快的速度打开相 关测量, 如果延迟的话容易掉话。 不过, 本发明不排除采用其它基于直 接反映 UE业务质量的上行和下行链路传输信道误块率的判决规则。
上述打开测量的控制流程也适用于频间测量,只需要把其中的 "系统 间测量"改为 "频间测量"就可以了, 其他环节相同, 在此不再赘述。
综上所述,采用本发明方法可以在保证用户业务质量和启闭系统间测 量的时机之间达到一个最优化的控制。 工业实用性
本发明的控制系统间测量和频间测量的方法,可以应用于通信系统中 宽带的码分多址系统中的系统切换, 具有广泛的工业应用前景。
