为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对实 施例或现有技术描述中所需要使用的附图作一简单地介绍， 显而易见地， 下 面描述中的附图是本发明的一些实施例， 对于本领域普通技术人员来讲， 在 不付出创造性劳动性的前提下， 还可以根据这些附图获得其他的附图。
图 1为本发明业务质量处理方法实施例一的流程图；
图 2为本发明业务质量处理方法实施例二的流程图；
图 3为本发明业务质量处理方法实施例三的流程图；
图 4为本发明业务质量处理装置实施例一的结构示意图；
图 5为本发明业务质量处理装置实施例二的结构示意图；
图 6为本发明业务质量处理设备实施例一的结构示意图。 具体实施方式 为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描述， 显然， 所描述的实施例是本发明一部分实施例， 而不是全部的实施例。 基于 本发明中的实施例， 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
图 1为本发明业务质量处理方法实施例一的流程图。 本实施例的执行主 体可以为业务质量处理装置， 该装置既可以是一能够对应用层数据包进行抓 包的独立网元， 也可以部署在服务网关 （Serving Gateway, 简称 S-GW) 、 演进型基站（ evolved Node B，简称 eNB )、服务 GPRS支持节点（ Serving GPRS Support Node, 简称 SGSN) 、 网关 GPRS支持节点 (Gateway GPRS Support Node,简称 GGSN)或者无线网络控制器（Radio Network Controller,简称 RNC) 中， 该装置可以通过软件和 /或硬件实现。 如图 1所示， 本实施例的方法可以 包括：
歩骤 101、 获取流媒体服务的应用层数据包。
具体来说， 流媒体服务过程中， 应用层数据包会在网络中的网元之间传 输， 本实施例例如可以在两网元之间的接口上获取流媒体服务的应用层数据 包。 例如在 RNC和 SGSN/GGSN间的接口、 eNB和 S-GW间的接口， 获取 流媒体服务的应用层数据包。
歩骤 102、 获取流媒体服务对应的流媒体播放器的缓冲时延。 目前缓冲时延无法通过应用层数据获取到， 而对初始播放成功率、 初始 播放时延、 中断时延等流媒体服务的服务质量的统计需要用到缓冲时延的信 息。
具体来说， 现有的获取流媒体服务对应的流媒体播放器的缓冲时延方法 是通过配置固定的缓冲时延， 而不同的流媒体服务对应的流媒体播放器的缓 冲时延配置可能不同， 最终导致对流媒体播放服务进行服务质量统计时准确 度不高。例如优酷和搜狐网站的流媒体播放器缓冲时延分别是 20s和 10s， 但 现有的方法中将两个网站的流媒体播放器的缓冲时延都配置为 12s，就导致缓 冲时延与实际配置不同， 从而导致流媒体播放服务服务质量统计不准确。
本实施例针对不同的流媒体服务器， 其对应的流媒体播放器的缓冲时延 是动态获取的， 从而能够得到不同的流媒体服务器对应的准确的缓冲时延， 进而可以采用准确的缓冲时延对流媒体播放服务进行服务质量统计。
需要说明的是， 歩骤 101和歩骤 102可以同时执行， 也可以歩骤 102在 前， 歩骤 101在后， 本实施例中不加限制。
歩骤 103、 根据缓冲时延和应用层数据包， 对流媒体服务进行服务质量 统计。
具体来说， 本实施例可以通过解析应用层数据包， 进行业务分类以及得 到流媒体传输的码率， 由于数据量 =缓冲时间 X码率， 根据缓冲时延和码率就 可得到流媒体在播放前需要的缓冲数据量， 根据这些信息对流媒体服务进行 服务质量统计。
该服务质量统计， 例如可以是对初始播放成功率的统计， 该初始播放成 功率是流媒体播放器能够缓冲到各流媒体服务对应的流媒体播放器配置的缓 冲数据量后成功开始播放的比例； 又例如可以直接采用该缓冲时延作为一个 服务质量。 又例如， 可以是对中断时延的统计， 与初始播放的情况类似， 该 中断时延是从流媒体播放器数据清空到再次缓冲到流媒体服务对应的流媒体 播放器配置的缓冲数据量开始播放流媒体服务的时延。
本实施例， 可以获取流媒体服务的应用层数据包以及流媒体服务对应的 流媒体播放器的缓冲时延， 并根据缓冲时延和应用层数据包， 对流媒体服务 的服务质量进行统计， 由于各种流媒体服务对应的流媒体播放器的缓冲时延 并非默认为相同的， 而是针对不同的流媒体服务器， 其对应的流媒体播放器 的缓冲时延是动态获取的， 从而能够得到不同的流媒体服务器对应的准确的 缓冲时延， 进而可以解决采用缓冲时延进行流媒体播放服务的服务质量统计 时出现的统计不准确的问题。
下面采用两个具体的实施例， 对图 1所示方法实施例的技术方案进行详 细说明。
图 2为本发明业务质量处理方法实施例二的流程图， 如图 2所示， 在本 实施例中， 可以包括：
歩骤 201、 存储各网站的流媒体播放器的缓冲时延；
具体地， 在本实施例中， 可以对各网站的流媒体播放器的缓冲时延进行 统计， 例如针对多个网站的流媒体播放器进行测试， 具体可以通过在用户设 备中打开各网站的流媒体服务进行统计，从而确定不同网站的缓冲时延配置。 然后， 可以存储各网站的流媒体播放器的缓冲时延， 例如可以存储网站的标 识与缓冲时延之间的对应关系。
例如， 与优酷网站标识对应的缓冲时延为 20s， 与搜狐网站标识对应的缓 冲时延为 10s。
歩骤 202、 从应用层数据包中获取提供流媒体服务的网站标识。
具体地， 通过解析应用层数据包， 即可获取提供流媒体服务的网站标识， 如优酷的网站标识， 或者搜狐的网站标识等。
歩骤 203、 获取与网站标识对应的流媒体播放器的缓冲时延。
在获取应用层数据包中包含的网站标识后， 即可采用歩骤 201 中存储的 网站标识与缓冲时延之间的对应关系， 找到该网站标识对应的缓冲时延。
歩骤 204、 从应用层数据包中获取流媒体传输的码率。
需要说明的是， 歩骤 204和歩骤 202可以同时执行， 即在一次获取过程 中同时获取网站标识和流媒体传输的码率。
歩骤 205、 根据码率和缓冲时延的乘积， 得到流媒体在播放前需要缓冲 的数据量。
歩骤 206、根据缓冲时延和 /或数据量， 对流媒体服务进行服务质量统计。 本实施例， 通过对各网站的流媒体播放器的缓冲时延配置进行统计并存 储， 从而可以获得不同流媒体服务对应流媒体播放器的缓冲时延， 并通过应 用层数据包中获取到流媒体传输的码率， 根据码率和缓冲时延的乘积得到流 媒体在播放前需要缓冲的数据量， 利用不同的流媒体服务器对应的准确的缓 冲时延和 /或数据量进行流媒体播放服务的服务质量统计， 进而可以解决采用 缓冲时延进行流媒体播放服务的服务质量统计时出现的统计不准确的问题。
图 3为本发明业务质量处理方法实施例三的流程图， 如图 3所示， 本实 施例与图 2所示实施例的区别在于不需要对各网站的流媒体播放器的缓冲时 延进行统计与存储， 在本实施例中， 可以包括：
歩骤 301、 从应用层数据包中获取流媒体服务对应的流媒体播放器的缓 冲时延。
具体地， 目前应用层数据包中没有携带缓冲时延， 而缓冲时延是各流媒 体服务器配置的， 在本实施例中， 流媒体播放器可以在发起业务请求数据包 中携带缓冲时延， 或者在流媒体数据头文件中携带缓冲时延信息。
歩骤 302、 从应用层数据包中获取流媒体传输的码率。
需要说明的是， 歩骤 301和歩骤 302可以同时执行， 即在一次获取过程 中同时获取缓冲时延和流媒体传输的码率。
歩骤 303、 根据码率和缓冲时延的乘积， 得到流媒体在播放前需要缓冲 的数据量。
歩骤 304、根据缓冲时延和 /或数据量， 对流媒体服务进行服务质量统计。 本实施例， 通过应用层数据实时交互就可以获取不同的流媒体服务器对 应的准确的缓冲时延， 并通过应用层数据包中获取到流媒体传输的码率， 根 据码率和缓冲时延的乘积得到流媒体在播放前需要缓冲的数据量， 利用不同 的流媒体服务器对应的准确的缓冲时延和 /或数据量进行流媒体播放服务的 服务质量统计， 进而可以解决采用缓冲时延进行流媒体播放服务的服务质量 统计时出现的统计不准确的问题。
