Description

提高小流量用户^ ^的方法、 装置和系统 本申请要求于 2011年 10月 19日提交中国专利局、 申请号为 201110320359.3、 发明名称为"提高小流量用户体验的方法、 装置和系统" 的中国专利申请的优先权, 其全部内容通过 ^!用结合在本申请中。 技术领域 本发明涉及通信技术领域, 尤其涉及一种提高小流量用户体验的方 法、 装置和系统。 背景技术 无线接入网中, 在传输用户的数据时, 对于空中接口等资源, 为了 提高带宽利用率, 往往釆用多用户共享的方式。 无线业务分为多种, 如 网页浏览、 网络电话、 网络游戏、 FTP (File Transfer Protocol, 文件传输 协议) 等, 有些业务属于时延敏感业务, 如网络电话、 网络游戏等, 用 户在使用这些业务时, 时延的增大会明显降低用户的体验, 因此空中接 口等资源的分配调度直接影响到用户的体验。由于不同用户的业务不同, 用户产生的流量各不相同, 当多个用户共享带宽资源时, 由于带宽受限, 用户间就会产生竟争, 大容量需求的用户将会抢占小流量用户的资源, 导致小流量用户数据传输时延增大, 而小流量用户使用的业务往往是时 延敏感业务, 因此小流量用户的用户体验会明显降低。
现有技术中, 为了解决用户间产生资源竟争时小流量用户体验比平 时差的问题, 往往釆用 DPI ( Deep Packet Inspection, 深度报文检测)技 术进行报文分析, 在传输层识别出应用层的业务类型, 即识别出网页浏 览、 网络电话、 FTP等具体业务类型, 根据具体的业务类型设置不同的 调度优先级, 从而对高优先级业务优先分配资源, 保证了时延敏感业务 的质量。
发明人发现, 现有技术违背了协议分层透明的原则, DPI对 CPU消 耗过大, 增加了设备成本, 应用层业务变化频繁, DPI 需要不断适应应 用层的变化。 发明内容 本发明实施例提供了一种提高小流量用户体验的方法、装置和系统, 用以解决用户间产生资源竟争的时候, 小流量用户体验降低的问题。
本发明一方面提供了一种提高小流量用户体验的方法,该方法包括: 基站控制器 BSC周期性统计终端的平均数据传输速率;
BSC将所述平均数据传输速率与设定的门限做比较, 判断所述平均 数据传输速率是否小于所述设定的门限;
若所述平均数据传输速率小于所述设定的门限, 所述 BSC向基站收 发台 BTS发送第一优先级调整命令, 所述第一优先级调整命令中携带调 整所述终端调度优先级为高优先级的信息, 以使得所述 BTS调整所述终 端的调度优先级为高优先级。
本发明另一方面提供了一种提高小流量用户体验的基站控制器 BSC, 包括:

比较模块: 用于将所述平均数据传输速率与设定的门限做比较, 判 断所述平均数据传输速率是否小于所述设定的门限;
发送模块: 用于当所述平均数据传输速率小于所述设定的门限时, 向基站收发台 BTS发送优先级调整命令, 所述命令中携带调整所述终端 调度优先级为高优先级的信息。
本发明再一方面提供了一种提高小流量用户体验的系统, 其特征在 于, 包括:
基站控制器 BSC: 用于周期性统计终端的平均数据传输速率, 将所 述平均数据传输速率与设定的门限做比较, 若所述平均数据传输速率小 于所述设定的门限, 则向基站收发台 BTS发送第一优先级调整命令, 所 述第一优先级调整命令中携带调整所述终端调度优先级为高优先级的信 息;
基站收发台 BTS: 用于接收所述 BSC发送的第一优先级调整命令, 调整所述终端的调度优先级为高优先级。
通过本发明实施例公开的方法、 BSC和系统, 首先统计当前接入终 端的平均数据传输速率, 然后将所述平均数据传输速率与设定的门限比 较, 根据比较结果进行终端调度优先级的相应调整,从而解决了接入网中 用户间产生资源竟争的时候, 大流量用户抢占小流量用户的带宽资源的 问题, 保证了小流量用户优先获得频带资源, 提高了小流量用户体验。 本发明提供的技术方案不去识别业务类型, 而是根据终端平均数据传输 速率调整终端调度优先级, 不违背协议透明的原则, 实现简单, 不会明 显增加设备成本, 同时能够达到保证小流量用户体验的目的。 附图说明 图 1为现有技术 CDMA EVDO数据通信系统结构图;

图 4为本发明实施例提供的一种提高小流量用户体验的基站控制器 BSC示意图;
图 5 为本发明实施例提供的一种提高小流量用户体验的系统示意 图。 具体实施方式 为使本发明的目的、 技术方案以及优点表达得更清楚明白, 下面结 合具体实施例和附图详细说明本发明提供的技术方案。
在无线通信系统中, 带宽受限的链路一般釆用多用户共享抢占的策 略, 这样可以最大限度提高带宽利用率。 如图 1所示, 为 CDMA EVDO ( Code Division Multiple Access Evolution Data Optimized,码分多址演进 数据最优) 数据通信系统结构, 在基站收发台 BTS和基站控制器 BSC之 间的 Abis接口、 BTS和终端间的空中接口, 是整个系统的带宽瓶颈, 这 两部分接口资源都是多用户共享。 当用户数目增加时, 每个用户所获得 的带宽减小, 用户体验降低, 这种降低对于小流量用户尤为明显。
本发明实施例公开了一种提高小流量用户体验的方法。
本实施例以 E VD 0网络为例, 来说明当多个用户产生资源竟争时, 提高小流量用户体验的方法。
本实施例中, 基站控制器 BSC周期性统计用户终端的平均数据传输 速率, 当平均数据传输速率低于设定的门限时,例如门限值可设为 100kbit/s, 则能够判定使用该终端的用户为小流量用户, 可以提高该终 端的基站调度优先级。 如果多个用户都是小流量用户, 他们的调度优先 级是相同的, 小流量用户的调度优先级是针对大流量用户而言的, 大流 量用户和小流量用户的界定是根据他们的整体平均数据传输速率判定, 门限的值可以灵活设定,动态变化, 为了实现简便也可以釆用静态门限。
如图 2所示, 本实施例提供了一种提高小流量用户体验的方法, 具体 步骤如下:
步骤 201、 基站控制器 BSC周期性统计终端的平均数据传输速率。 BSC在计算终端的平均数据传输速率 R时,可以首先统计终端在每个 统计周期 T内接收或发送的数据量 S Byte,统计周期可以根据运营商的要 求等因素设定, 例如 60秒; 然后计算当前用户的平均数据传输速率 R kbit/s, R=S*8/ ( T*1024 ) 。 在统计终端的平均数据传输速率时, 可以统 计下行平均数据传输速率, 也可以统计上行平均数据传输速率。
步骤 202、 BSC将所述平均数据传输速率与设定的门限做比较, 判断 所述平均数据传输速率是否小于所述设定的门限。
BSC将步骤 201中得到的 R与设定的门限,例如 100kbit/s比较, 根据比 较的结果可以判断出相应终端用户是否为小流量用户, 若 R小于设定门 限值, 则可以判定该用户为小流量用户, 否则为大流量用户。
小流量用户是针对大流量用户而言的, 大流量用户和小流量用户的 界定是根据他们的整体数据流量判定, 门限的值可以灵活设定,动态变 化, 例如可以根据运营商的要求等因素灵活设定, 为了实现简便也可以 釆用静态门限。
步骤 203、 若所述平均数据传输速率小于所述设定的门限, BSC向基 站收发台 BTS发送第一优先级调整命令, 所述第一优先级调整命令中携 带调整所述终端调度优先级为高优先级的信息, BTS调整所述终端的调 度优先级为高优先级。
调整终端优先级的功能可以通过 BSC向 BTS发送第一优先级调整命 令, BTS执行所述第一优先级调整命令来完成。 若所述平均数据传输速 率小于所述门限, BSC向 BTS发送优先级调整命令, 所述命令中携带调 整对应终端调度优先级为高优先级的信息。
BTS接收 BSC发送的优先级调整命令, 调整相应终端的调度优先级。 由于 BTS接收到的优先级调整命令中携带调整对应终端优先级为高优先 级的信息, BTS调整该用户的调度优先级为高优先级。
通过本发明实施例公开的方法, 基站控制器 BSC首先统计终端的平 均数据传输速率, 将所述平均传输速率与设定的门限比较, 若平均数据 传输速率小于所述门限, 则调整相应终端的调度优先级为高优先级, 从 而解决了接入网中用户间产生资源竟争的时候, 大流量用户抢占小流量 用户带宽资源的问题, 保证了小流量用户优先获得频带资源, 提高了小 流量用户的体验。
可选的,在上述实施例的基础上,如图 3所示,还可以包括以下步骤: 步骤 204、 若所述平均数据传输速率大于或等于所述设定的门限, BSC向 BTS发送第二优先级调整命令, 所述第二优先级调整命令中携带 调整所述终端调度优先级为普通优先级的信息, BTS调整所述终端的调 度优先级为普通优先级。
调整终端优先级的功能可以通可以通过 BSC向基站收发台 BTS发送 第二优先级调整命令, BTS执行所述第二优先级调整命令来完成。 若所 述平均数据传输速率大于或等于所述设定的门限, BSC向 BTS发送第二 优先级调整命令, 所述命令中携带调整对应终端调度优先级为普通优先 级的信息。
BTS接收 BSC发送的第二优先级调整命令, 调整相应终端的调度优 先级。 由于 BTS接收到的优先级调整命令中携带调整对应终端优先级为 普通优先级的信息, BTS调整该终端的调度优先级为普通优先级。
在本发明方法实施例中, BTS在调整终端调度优先级时, 可以通过 修改存储在 BTS的调度优先级参数来实现。 将终端的调度优先级参数调 高, 就达到了将调度优先级调为高优先级的目的。调度优先级参数越大, 用户的调度权重越大, 默认情况下, 所有终端的调度优先级是相同的。
需要说明的是, 本发明实施例中终端调度优先级分为两级, 即高优 先级和普通优先级, 默认情况下, 所有终端都是普通优先级。 也可以将 终端调度优先级分为多级, 提高小流量用户体验的过程可以釆用本实施 例中类似的方法。
通过应用本发明实施例公开的方法, BSC首先统计终端的平均数据 传输速率, 然后将所述平均数据传输速率与设定的门限比较, , 根据比 较结果进行终端调度优先级的相应调整, 从而解决了接入网中用户间产 生资源竟争的时候, 大流量用户抢占小流量用户的带宽资源的问题, 保 证了小流量用户优先获得频带资源, 提高了小流量用户体验。
需要说明的是, 以上方法实施例是以 CDMA EVDO通信系统为例, 但在其它通信系统中, 所述方法仍然适用。 例如通用移动通信系统 UMTS , 长期演进 LTE等。 在 UMTS系统中, 接入网设备包括基站 NodeB 和无线网络控制器 RNC; 在 LTE系统中, 则包括远端射频单元 RRU和基 带单元 BBU。 相应的统计终端平均数据传输速率和将所述平均数据传输 速率与设定的门限做比较以及发送优先级调整命令的步骤可以借助 RNC 或 BBU实现, 调整终端调度优先级的步骤可以借助 NodeB与 RNC协同或 RRU与 BBU协同来实现。
本发明实施例公开了一种提高小流量用户体验的基站控制器 BSC。 如图 4所示, 所述 BSC包括:

比较模块 402: 用于将所述平均数据传输速率与设定的门限做比较, 判断所述平均数据传输速率是否小于所述设定的门限。
发送模块 403 : 用于当所述平均数据传输速率小于所述设定的门限 时, 向基站收发台 BTS发送优先级调整命令, 所述命令中携带调整所述 终端调度优先级为高优先级的信息, 以使得 BTS调整所述终端的调度优 先级为高优先级。
本实施例中,统计模块 401具体可以用于首先统计当前接入终端在每 个统计周期内接收或发送的数据量, 然后计算当前用户的平均数据传输 速率。 在统计平均数据传输速率时, 可以统计下行平均数据传输速率, 也可以统计上行平均数据传输速率。
本实施例中, 判断模块 402用于将模块 401得到的终端平均数据传输 速率与设定的门限比较, 若所述平均数据传输速率小于门限值, 则可以 判定所述终端的用户为小流量用户, 否则为大流量用户。 可选的 ,发送模块 403还用于当所述平均数据传输速率大于或等于所 述设定的门限时, 向 BTS发送优先级调整命令, 所述命令中携带调整对 应终端调度优先级为普通优先级的信息。
通过应用本发明实施例公开的 BSC , 可以统计出终端的平均数据传 输速率, 根据与设定的门限的比较结果, 向 BTS发送优先级调整命令, 以使得 BTS调整相应终端的调度优先级, 保证了小流量用户优先获得频 带资源, 提高了小流量用户体验。
本发明实施例公开了一种提高小流量用户体验的系统。
如图 5所示, 该系统包括:
基站控制器 BSC501 : 用于周期性统计终端的平均数据传输速率, 将 所述平均数据传输速率与设定的门限做比较, 若所述平均数据传输速率 小于所述设定的门限, 则向基站收发台 BTS发送第一优先级调整命令, 所述第一优先级调整命令中携带调整所述终端调度优先级为高优先级的 信息。
在统计终端平均数据传输速率时,可以统计下行平均数据传输速率, 也可以统计上行平均数据传输速率。
基站收发台 BTS502: 用于接收 BSC发送的第一优先级调整命令, 调 整所述终端的调度优先级为高优先级。
在上述实施例的基础上, 可选的, BSC还用于当所述平均数据传输 速率大于或等于所述设定的门限时, 向 BTS发送第二优先级调整命令, 所述第二优先级调整命令中携带调整对应终端调度优先级为普通优先级 的信息。 BTS用于接收 BSC发送的第二优先级调整命令, 调整相应终端 调度优先级为普通优先级。
需要说明的是, 上述系统实施例中, 终端调度优先级分为两级, 即 普通优先级和高优先级, 默认情况下, 所有终端都是普通优先级。 也可 以将终端调度优先级分为多级, 提高小流量用户体验的系统可以釆用本 实施例中类似的结构。
通过应用本发明实施例公开的系统, BSC首先统计终端的平均数据 传输速率, 然后将上述平均数据传输速率与设定的门限比较, 根据比较 结果向 BTS发送优先级调整命令, BTS进行终端调度优先级的相应调整, 从而解决了接入网中用户间产生资源竟争的时候, 大流量用户抢占小流 量用户的带宽资源的问题, 保证了小流量用户优先获得频带资源, 提高 了小流量用户体验。
需要说明的是, 以上系统实施例是以 CDMA EVDO通信系统为例, 但在其它通信系统中, 所述系统仍然适用, 例如通用移动通信系统 UMTS, 长期演进 LTE等。 在 UMTS系统中, 接入网设备包括基站 NodeB 和无线网络控制器 RNC; 在 LTE系统中, 则包括远端射频单元 RRU和基 带单元 BBU。 相应的统计终端数据传输速率和将所述平均数据传输速率 与设定的门限做比较以及发送优先级调整命令的功能可以借助 RNC或 BBU实现, 调整终端调度优先级的功能可以借助 NodeB或 RRU实现。
通过本发明实施例公开的方法、 装置和系统, 首先统计当前接入终 端的平均数据传输速率, 然后将所述平均数据传输速率与设定的门限比 较, 根据比较结果进行终端调度优先级的相应调整, 从而解决了接入网 中用户间产生资源竟争的时候 , 大流量用户抢占小流量用户的带宽资源 的问题,保证了小流量用户优先获得频带资源,提高了小流量用户体验。 本发明提供的技术方案不去识别业务类型, 而是根据终端平均数据传输 速率调整终端调度优先级, 不违背协议透明的原则, 实现简单, 不会明 显增加设备成本, 同时能够达到保证小流量用户体验的目的。
通过以上的实施方式的描述, 本领域的技术人员可以清楚地了解到 本发明可借助软件加必需的硬件平台的方式来实现, 当然也可以全部通 过硬件来实施,但很多情况下前者是更佳的实施方式。基于这样的理解, 本发明的技术方案对背景技术做出贡献的全部或者部分可以以软件产品 的形式体现出来, 该计算机软件产品可以存储在存储介质中, 如
ROM/RAM, 磁碟、 光盘等, 包括若干指令用以使得一台计算机设备, 可以是个人计算机, 服务器, 或者网络设备等, 执行本发明各个实施例 或者实施例的某些部分所述的方法。
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 照前述实施例对本发明进行了详细的说明, 本领域的普通技术人员应当 理解: 其依然可以对前述各实施例所记载的技术方案进行修改, 或者对 其中部分技术特征进行等同替换; 而这些修改或者替换, 并不使相应技 术方案的本质脱离本发明各实施例技术方案的精神和范围。
