本发明属于互联网技术领域，具体地说，涉及一种网络服务质量策略的调整方法和装置。
背景技术
QoS(Quality of Service，服务质量)指一个网络能够利用各种基础技术，为指定的网络通信提供更好的服务能力，是用来解决网络延迟和阻塞等问题。在正常情况下，如果网络只用于特定的无时间限制的应用系统，并不需要QoS，例如Web应用、E-mail等。但是对关键应用和多媒体应用就十分必要。当网络过载或拥塞时，QoS能确保重要业务量不受延迟或丢弃，同时保证网络的高效运行。
作为无线网络的服务质量(Quality of Service，QoS)策略，通常定义了各种网络连接类型和内容，例如，无线多媒体(WMM，Wi-Fi Multimedia)策略，定义了“语音(AC_VI)”、“视频(AC_VO)”、“尽力而为(AC_BE)”和“低优先级数据(AC_BK)”，以此来优化无线网络通信的质量，以保障应用程序与网络资源建立稳定连接。即通过对不同的接入类型采取不同的优先级，提供高质量的数据、语音、音乐、视频应用的网络连接性能。
在QoS策略中尽管各种接入类型在设计时是按照从高到低的优先级设计的，但实际上并没有默认的优先级策略，而是让路由器、AP厂商或用户选择最适合的网络策略，并决定采用具有哪种优先级的网络。例如，用户可能倾向于给予视频比语音更高的优先级。当前的无线路由器通常采用固定的QoS策略，在家用路由器的接入设备中，智能移动终端设备越来越普遍，智能移 动终端设备上的不同的应用程序对路由器QoS策略的需求也许完全不同。因此，固定不变的QoS策略无法适应不同的应用程序对网络QoS策略的需求。然而目前用户只能在使用不同的App时频繁登陆路由器来修改QoS策略配置，会耗费用户大量的时间和精力。

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是本发明实施例提供的一种网络服务质量策略的调整方法，适用于路由器设备，该方法包括以下步骤。
在步骤S10中，接收到来自终端设备的第一报文，第一报文包括被启动的应用程序的预设服务质量策略。
不同的应用程序，其业务侧重点不同，因此对不同类型的网络数据的需求也不相同，从而导致各个应用程序所适合的QoS策略也不会完全相同。例 如，有的应用程序侧重于语音数据，有的应用程序侧重于视频数据。因此，为每个应用程序需要预设适合该应用程序的QoS策略。该预设QoS策略可以由应用程序开发者提供，或者由终端设备的操作系统或者安装的应用程序管理软件根据该应用程序的类型或业务侧重点来分配。当应用程序被启动后，终端设备向路由器设备发送的第一报文包括该被启动的应用程序的预设QoS策略。该第一报文可以是TCP(传输控制协议，Transmission Control Protocol)报文或UDP(用户数据协议，User Datagram Protocol)报文，该被启动的应用程序的预设QoS策略位于TCP报文或UDP报文的数据(Data)字段。在本发明实施例中，QoS策略包括DSCP(差分服务代码点，Differentiated Services Code Point)策略、WMM(Wi-Fi Multimedia，无线多媒体)策略等等。
在步骤S11中，根据被启动的应用程序的预设服务质量策略调整本地服务质量策略，得到调整后的本地服务质量策略。
该路由器设备在应用层提供一个程序，以接收来自终端设备的报文，并解析出报文数据对路由器设备的QoS策略进行调整。
路由器设备根据第一报文中的预设QoS策略调整本地服务质量策略。如果该路由器设备还没有根据应用程序的预设QoS策略对本地QoS策略进行过调整，则该路由器设备的本地QoS策略为默认的QoS策略，即有可能是路由器设备的出厂设置。路由器设备判断当前的本地QoS策略是否为默认的QoS策略，当本地QoS策略为默认的QoS策略时，将本地QoS策略调整为被启动的应用程序的预设QoS策略，使路由器设备的本地QoS策略能够适应被启动的应用程序的数据需求，提高网络服务质量。当本地QoS策略不是默认的QoS策略时，说明路由器设备的本地QoS策略已根据其他应用程序的预设QoS策略进行过调整，此时，将本地QoS策略和该预设QoS策略按照预定算法策略进行计算，得到调整后的本地QoS策略。例如，将被启动的应用程序的预设QoS策略进行加权计算得到调整后的本地QoS策略，或者将本地QoS策略与被启动的应用程序的预设QoS策略中的各个参数取平均值，从而得到尽可能兼顾多个应用程序的本地QoS策略，使路由器设备能同时为多个应用程序提供较好的网络服务质量。
在应用程序被关闭时，该网络服务质量策略的调整方法如图2所示，还包括以下步骤。
在步骤S20中，接收到来自终端设备的第二报文，第二报文由终端设备在关闭应用程序时发出。
该第二报文也可以是TCP报文或UDP报文。
在步骤S21中，将当前调整后的本地服务质量策略恢复到调整之前的本地服务质量策略。
路由器设备不再需要考虑被关闭的应用程序的QoS策略，从而去除该被关闭的应用程序的预设QoS策略对本地QoS策略的影响，使本地QoS策略尽可能适合其他未被关闭的应用程序即可。将当前调整后的本地QoS策略恢复到调整之前的QoS策略时，如果本地QoS策略在调整之前是默认QoS策略，则恢复到默认QoS策略，如果本地QoS策略在特征之前不是默认QoS策略，则恢复到调整之前的本地QoS策略。从而使恢复后的本地QoS策略尽可能的适合其他应用程序的网络需求，使路由器设备保持较高的网络服务质量。
图3是本发明实施例提供的一种网络服务质量策略的调整方法，适用于路由器设备，该方法包括以下步骤。
在步骤S30中，接收到来自终端设备的第一报文，第一报文包括被启动的应用程序的标识和被启动的应用程序的预设服务质量策略。
该第一报文是由终端设备在检测到有应用程序被启动时向路由器设备发送的。该第一报文包括被启动的应用程序的标识，该标识用于区分不同的应用程序。该第一报文还包括该被启动的应用程序的预设QoS策略。不同的应用程序，其业务侧重点不同，因此对不同类型的网络数据的需求也不相同，从而导致各个应用程序所适合的QoS策略也不会完全相同。例如，有的应用程序侧重于语音数据，有的应用程序侧重于视频数据。因此，为每个应用程序需要预设适合该应用程序的QoS策略。该预设QoS策略可以由应用程序开发者提供，或者由终端设备的操作系统或者安装的应用程序管理软件根据该应用程序的类型或业务侧重点来分配。当应用程序被启动后，终端设备向路由器设备发送的第一报文包括该被启动的应用程序的预设QoS策略。该第一报文可以是TCP(传输控制协议，Transmission Control Protocol)报文或 UDP(用户数据协议，User Datagram Protocol)报文，该被启动的应用程序的标识和预设QoS策略位于TCP报文或UDP报文的数据(Data)字段。在本发明实施例中，QoS策略包括DSCP(差分服务代码点，Differentiated Services Code Point)策略、WMM(Wi-Fi Multimedia，无线多媒体)策略等等。
该路由器设备在应用层提供一个程序，以接收来自终端设备的报文，并解析出报文数据对路由器设备的QoS策略进行调整。
在步骤S31中，在应用程序标识集合中，添加被启动的应用程序的标识。
该应用程序标识集合，用来记录各个终端设备正在运行的应用程序。路由器设备从第一报文解析出被启动的应用程序的标识，将该被启动的应用程序标识添加到应用程序标识集合。
在步骤S32中，根据被启动的应用程序的预设服务质量策略调整本地服务质量策略，得到调整后的本地服务质量策略。
路由器设备根据第一报文中的预设QoS策略调整本地服务质量策略。如果该路由器设备还没有根据应用程序的预设QoS策略对本地QoS策略进行过调整，则该路由器设备的本地QoS策略为默认的QoS策略，即有可能是路由器设备的出厂设置。路由器设备判断当前的本地QoS策略是否为默认的QoS策略，当本地QoS策略为默认的QoS策略时，将本地QoS策略调整为被启动的应用程序的预设QoS策略，使路由器设备的本地QoS策略能够适应被启动的应用程序的数据需求，提高网络服务质量。当本地QoS策略不是默认的QoS策略时，说明路由器设备的本地QoS策略已根据其他应用程序的预设QoS策略进行过调整，在应用程序标识集合中，除了步骤S11添加的被启动的应用程序的标识，还包括其他已经启动的应用程序的标识，此时，将应用程序标识集合中多个应用程序的预设QoS策略进行加权计算得到调整后的本地QoS策略。例如，可依据应用程序类别确定各个应用程序的预设QoS策略的权重值，再根据该权重值计算出调整后的本地QoS策略，或者对多个应用程序的预设QoS策略中的各个参数取平均值，从而得到尽可能兼顾多个应用程序的本地QoS策略，使路由器设备能同时为多个应用程序提供较好的网络服务质量。
在应用程序被关闭时，该服务质量策略的调整方法如图4所示，还包括以下步骤。
在步骤S40中，接收到来自终端设备的第二报文，第二报文包括被关闭的应用程序的标识。
当终端设备有应用程序被关闭时，终端设备发送第二报文至路由器设备。该第二报文也可以是TCP报文或UDP报文，包括被关闭的应用程序的标识，该被关闭的应用程序的标识位于TCP报文或UDP报文的数据(Data)字段。
在步骤S41中，在应用程序标识集合中，删除被关闭的应用程序的标识。
路由器设备从第二报文解析出被关闭的应用程序的标识，在应用程序标识集合中，删除该被关闭的应用程序的标识。
在步骤S42中，将当前调整后的本地服务质量策略恢复到调整之前的本地服务质量策略。
路由器设备不再需要考虑被关闭的应用程序的QoS策略，从而去除该被关闭的应用程序的预设QoS策略对本地QoS策略的影响，使本地QoS策略尽可能适合应用程序标识集合中的其他应用程序即可。在将当前调整后的本地服务质量策略恢复到调整之前的本地服务质量策略时，首先判断应用程序标识集合是否已不包括任何应用程序的标识；当应用程序标识集合已不包括任何应用程序的标识时，将本地QoS策略恢复为默认的QoS策略；当应用程序标识集合还包括其他应用程序的标识时，对本地QoS策略根据被关闭的应用程序的预设QoS策略进行除权计算，得到恢复后的本地QoS策略。例如，该除权计算可以是对应用程序标识集合中所有其他应用程序的预设QoS策略的按照各自的权重值进行计算，或者对应用程序标识集合中所有其他应用程序的预设QoS策略的各项参数取平均值，从而使恢复后的本地QoS策略尽可能的适合应用程序标识集合中其他应用程序的网络需求，使路由器设备保持较高的网络服务质量。
本发明实施例还提供了一种网络服务质量策略的调整方法，适用于终端设备，该方法包括：当检测到应用程序被启动时，发送第一报文至路由器设备，第一报文包括被启动的应用程序的预设服务质量策略，由路由器设备根据被启动的应用程序的预设服务质量策略调整本地服务质量策略，得到调整 后的本地服务质量策略。
终端设备检测应用程序的启动和关闭，各个应用程序的预设QoS策略可以由应用程序开发者提供，也可以由终端设备的操作系统或者安装的应用程序管理软件根据该应用程序的类型或业务侧重点进行分配。终端设备发送第一报文至路由器设备时，可以利用该被启动的应用程序的通信接口、安装的应用程序管理软件的通信接口或者通过操作系统的通信接口与路由器设备进行数据通信。由路由器设备根据第一报文中被启动的应用程序的预设QoS策略对本地QoS策略进行调整，使调整后的本地QoS策略尽可能适合该被启动的应用程序。
该网络服务质量策略的调整方法进一步包括：当检测到应用程序被关闭时，发送第二报文至路由器设备，由路由器设备将当前调整后的本地服务质量策略恢复到调整之前的本地服务质量策略。
检测到应用程序被关闭时，可以在该应用程序被关闭的同时通过该应用程序的通信接口向路由器设备发送第二报文，也可以在该应用程序被关闭后通过安装的应用程序管理软件的通信接口或者操作系统的通信接口向路由器设备发送第二报文。由路由器设备将当前调整后的本地QoS策略恢复到调整之前的本地QoS策略，去除该被关闭的应用程序的预设QoS策略对路由器设备本地QoS策略的影响，使恢复后的本地QoS策略尽可能适合其他未被关闭的应用程序。
在一个实施例中，本发明实施例还提供了一种网络服务质量策略的调整方法，适用于终端设备，该方法包括：当检测到应用程序被启动时，发送第一报文至路由器设备，第一报文包括被启动的应用程序的标识和被启动的应用程序的预设服务质量策略，由路由器设备在应用程序标识集合中添加被启动的应用程序的标识，并根据被启动的应用程序的预设服务质量策略调整本地服务质量策略，得到调整后的本地服务质量策略。
终端设备检测应用程序的启动和关闭，各个应用程序的预设QoS策略可以由应用程序开发者提供，也可以由终端设备的操作系统或者安装的应用程序管理软件根据该应用程序的类型或业务侧重点进行分配。终端设备发送第一报文至路由器设备时，可以利用该被启动的应用程序的通信接口、安装的 应用程序管理软件的通信接口或者通过操作系统的通信接口与路由器设备进行数据通信。由路由器设备根据第一报文中被启动的应用程序的标识和该被启动的应用程序的预设QoS策略对本地QoS策略进行调整，使调整后的本地QoS策略尽可能适合被启动的应用程序。
该网络服务质量策略的调整方法进一步包括：当检测应用程序被关闭时，发送第二报文至路由器设备，第二报文包括被关闭的应用程序的标识，由路由器设备在应用程序标识集合中删除被关闭的应用程序的标识，并从本地服务质量策略中去除被关闭的应用程序的预设服务质量策略。
检测到应用程序被关闭时，可以在该应用程序被关闭的同时通过该应用程序的通信接口向路由器设备发送第二报文，也可以在该应用程序被关闭后通过安装的应用程序管理软件的通信接口或者操作系统的通信接口向路由器设备发送第二报文。由路由器设备从应用程序标识集合中删除该被关闭的应用程序的标识，从而去除该应用程序的预设QoS策略对本地QoS策略的影响，使恢复后的QoS策略尽可能适合应用程序标识集合中剩余的其他未被关闭的应用程序。
下面通过几个应用实例对本发明实施例做进一步说明。
(一)调整路由器设备的DSCP策略
DSCP策略包括AF(保证转发，Assured Forwarding)、EF(无阻碍转发，Expedited Forwarding)等多个参数。以路由器设备DSCP策略的EF参数为例，EF参数主要用于低延迟、低抖动和低丢包率的业务，这类业务通常需要相对稳定的速率，需要在转发设备中进行快速转发，该EF参数默认的DSCP值为46。
当终端设备开启一个主要用于网络电话功能的应用程序A时，由于网路电话需要保证数据具有较高的实时性和低抖动，该应用程序A的预设DSCP策略中EF参数的DSCP值为56，终端设备发送第一报文至路由器设备，该第一报文包括应用程序A的标识，例如“app_A”，以及应用程序A的预设DSCP策略，其中EF参数的DSCP值为56。路由器设备接收到第一报文后，将应用程序A的标识“app_A”添加到应用程序标识集合中。然后，路由器设备判断出当前的本地DSCP策略为默认的DSCP策略，因此，将本地DSCP策略调整为 应用程序A的预设DSCP策略，使路由器设备的本地的DSCP策略的EF参数从46调整为56，无阻碍转发的优先级变得更高，使网络服务更有利于以网络电话业务为主的应用程序A。
当终端设备中的应用程序B被启动时，该应用程序B侧重于视频播放业务，在其预设DSCP策略中，EF参数的DSCP值为46，终端设备再次发送第一报文至路由器设备，该第一报文中包括应用程序B的标识“app_B”以及应用程序B的预设DSCP策略。路由器设备接收到该第一报文后，在应用程序标识集合中添加应用程序B的标识“app_B”，判断出当前的本地DSCP策略已不是默认的DSCP策略，则将本地DSCP策略与应用程序B的预设DSCP策略中的各个参数进行加权平均。对于其中的EF参数来说，加权平均后DSCP值为51，路由器设备的本地DSCP策略中的EF参数的DSCP值被调整为51，以尽可能的同时满足应用程序A和应用程序B对于网络服务质量的需求。
当终端设备中的应用程序B被关闭时，终端设备发送第二报文至路由器设备，该第二报文包括应用程序B的标识“app_B”。路由器设备接收到该第二报文后，在应用程序标识集合中删除应用程序B的标识“app_B”，并判断出应用程序标识集合还包括其他应用程序A的标识，路由器设备对本地DSCP策略的各个参数根据应用程序B的预设DSCP策略进行除权平均，EF参数的DSCP值恢复为应用程序A的预设DSCP策略中EF参数的DSCP值，即从51调整为56，使路由器设备的DSCP策略更适合应用程序A的网络服务质量需求。
当终端设备中的应用程序A也被关闭时，终端设备再次发出第二报文至路由器设备，该第二报文包括应用程序A的标识“app_A”。路由器设备接收到第二报文后，在应用程序标识集合中删除该应用程序A的标识“app_A”，并判断出应用程序标识集合已不包括任何应用程序的标识，路由器设备将本地DSCP策略恢复为默认的DSCP策略，对于DSCP策略中的EF参数来说，EF参数的DSCP值从56恢复为默认值46。
(二)调整路由器设备的WMM策略
WMM策略包括AIFSN(Arbitration Inter Frame Spacing Number，仲裁帧间隙数)，CWMIN(Contending Windows MIN，最小竞争窗口)，CWMAX(Contending Windows MAX，最大竞争窗口)等多个参数，在此仅以AIFSN 参数为例进行说明，对其它参数的调整原理相同。AIFSN越小，即等待信道空闲的时间越短，越容易接入信道。因此，低优先级业务的AIFSN值要大于高优先级业务。
例如视频应用程序，通常对视频流拥有最高的优先级，假设该视频应用程序所需要的WMM策略如下表1所示：
表1：
Figure PCTCN2016082534-appb-000001
其中，Voice代表语音业务的优先级，Video代表视频业务数据的优先级，Best-effort代表“尽力而为”型业务数据的优先级，Back-ground代表较低优先级的背景数据的优先级。
当终端设备的视频应用程序开启时，该终端设备将该视频应用程序的预设WMM策略发送给无线路由器。
无线路由器接收到从该终端设备发送过来的第一报文，将该视频应用程序的标识添加到应用程序标识集合。无线路由器查看当前的本地WMM策略。如果是默认WMM策略，说明当前暂无其他应用程序的预设WMM策略需求，则直接按照该视频应用程序的预设WMM策略进行设置。
如果无线路由器发现此前已经根据其它应用程序的预设WMM策略调整了本地WMM策略，则需要对多个应用程序的预设WMM策略进行加权平均，计算出调整后的WMM策略。例如，已经有一个语音应用程序连接到该无线路由器，并且该语言应用程序的预设WMM策略如下表2所示：
表2：
Figure PCTCN2016082534-appb-000002
Figure PCTCN2016082534-appb-000003
此时，需要将新添加的视频应用程序和该语音应用程序的预设WMM策略进行加权平均计算，公式为：目标值＝AVERAGE(参数1,参数2,……)
计算后得到调整后的WMM策略如下：
表3：
Figure PCTCN2016082534-appb-000004
当该视频应用程序被关闭时，终端设备需要将关闭该视频应用程序的事件通知给无线路由器，向无线路由器发送第二报文。无线路由器接收到该第二报文后，将该视频应用程序的预设WMM策略从当前的本地WMM策略中去除。例如，该语音应用程序和视频应用程序加权平均后的WMM策略如表3所示，当视频应用程序被关闭时，无线路由器的本地WMM策略对视频应用程序的预设WMM策略进行除权平均，经重新计算后的本地WMM策略如下表4所示：
表4：
Figure PCTCN2016082534-appb-000005
Figure PCTCN2016082534-appb-000006
无线路由器的本地WMM策略恢复为在添加该视频应用程序之前的本地WMM策略。
