本发明实施例所涉及的视频优化方法，旨在解决现有技术中的视频优化方式对视频的优化效果不佳，用户体验较差的技术问题。
下面以具体地实施例对本发明的技术方案以及本发明的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图2为本发明实施例提供的视频优化方法实施例一的信令流程图。本实施例涉及的是网络设备获取正在使用视频业务的UE的视频MOS，以确定当前用户在通过UE使用视频业务时的视频质量和用户体验的具体过程。如图2所示，该方法包括如下步骤：
S101、网络设备向UE发送第一指示信息。
上述第一指示信息用于指示UE向网络设备发送UE的视频平均主观意见分(Mean Opinion Score，简称：MOS)，该视频MOS用于表征当前的视频质量等级。
具体的，当网络设备确定UE正在使用视频业务时，即用户正在使用UE 通过无线通信网络观看视频时，网络设备可以向UE发送第一指示信息，该第一指示信息用于指示UE将UE的视频MOS发送给网络设备。具体实现时，网络设备可以将上述第一指示信息携带在任一与UE交互的信令中发送给UE，例如：测量控制信令中等。
上述UE的视频MOS可以为任一能够表征当前的视频质量等级的信息，在本实施例中，上述视频质量等级具体可以分为如下五级：没有察觉(例如：视频播放流畅、无卡顿)、有察觉但不可厌(例如：视频播放基本流畅，偶尔有卡顿、且卡顿时间较短)、察觉且稍微可厌(例如：视频播放基本流畅，卡顿次数较多、但卡顿时间较短)、可厌但不令人反感(例如：视频播放卡顿次数过多、但卡顿时间较短)、极可厌且令人反感(例如：视频卡顿次数过多、且卡顿时间较长)，该视频质量等级具体可以根据用户的需求进行调整或者重新划分。可选的，上述视频MOS可以为视频MOS的分数，也可以为视频MOS的参数的值，还可以包括视频MOS的分数和视频MOS的参数的值等。其中，上述视频MOS的分数可以为与视频质量等级一一对应的分数，该对应关系例如可以如表1所示：
表1
视频MOS的分数 视频质量等级
5 没有察觉
4 有察觉但不可厌
3 察觉且稍微可厌
2 可厌但不令人反感
1 极可厌且令人反感
上述视频MOS的参数可以为用于计算视频MOS的分数的参数，例如：上述视频MOS的参数可以包括视频分辨率、视频比特率、视频编码、视频编码简介、初始缓冲时延、卡顿比例中的一个或多个。上述视频MOS参数所对应的定义具体可以如表2所示：
表2
Figure PCTCN2016074812-appb-000001
Figure PCTCN2016074812-appb-000002
S102、UE接收第一指示信息。
S103、UE根据该第一指示信息，获取UE的视频MOS。
具体的，若上述UE的视频MOS为视频MOS的分数，则UE在获取该视频MOS的分数时，可以是根据第一指示信息从UE上正在运行的视频APP中获取视频MOS的参数的值，然后根据所获取的视频MOS的参数的值，计算视频MOS的分数(即UE的视频MOS)。若上述UE的视频MOS为视频MOS的参数的值，则UE获取该视频MOS的参数的值时，可以是根据第一指示信息从UE上正在运行的视频APP中直接获取上述视频MOS的参数的值(即UE的视频MOS)。
其中，上述根据视频MOS的参数的值，计算视频MOS的分数的实现方式，具体可以根据用户的需求确定，本实施例对此不进行限定。
S104、UE向网络设备发送视频MOS。
具体的，UE可以将视频MOS携带在任一测量报告中发送给网络设备，还可以将视频MOS携带在任一与网络设备交互的信令中发送给网络设备，还可以将视频MOS直接发送给网络设备，具体可以根据用户的需求确定，本发明实施例对UE将视频MOS发送给网络设备的方式并不做限定。
S105、网络设备接收视频MOS。
具体的，当网络设备接收到UE发送的视频MOS之后，就可以根据该视频MOS所表征的当前的视频质量等级，获知用户当前在通过UE使用无线通信网络观看视频时的视频质量。可选的，当网络设备通过视频MOS获知当前的视频质量较好时，可以不采取优化措施以节省网络设备的开销，可选的， 当网络设备通过视频MOS获知当前的视频质量较差时，由于该视频MOS可以间接的反映观看当前视频所使用的网络的实际网络质量，因此网络设备可以通过该视频MOS获知当前的网络质量，从而可以从网络层面对视频进行优化，例如，网络设备可以通过增强信号覆盖、或者增加视频所占的网络资源、或者提高视频下载速率等方式来优化视频质量，以避免视频的卡顿，提升用户的体验。其中，上述视频质量较差的判定原则具体可以根据用户的需求确定，例如：上述视频质量较差的判定原则可以为当视频质量小于或等于“察觉且稍微可厌”时，确定视频质量较差。
现有技术中，UE会将当前观看视频时的QoE参数通过网络设备发送给视频服务器，以使得视频服务器通过QoE参数可以获知用户观看视频时的视频质量和用户体验，当用户体验不佳时，视频服务器可以通过调整视频格式的方式，例如：将视频格式从高清调整为标清的方式对用户所观看的视频进行优化，虽然这种方式可以减少用户在观看视频时出现视频卡顿的情况，但是由于改变了视频格式，使得用户在观看视频时，视频的质量仍然较差，用户体验较差。
而本实施例提供的视频优化方法，网络设备可以及时的获知正在使用视频业务的UE的视频MOS，进而通过该视频MOS所表征的当前的视频质量等级，确定用户在通过UE使用视频业务时的视频质量和用户体验，从而使得网络设备可以在视频质量较差，即用户体验较差时，能够从根本上优化视频质量，例如，增强信号覆盖、或者增加视频所占的网络资源、或者提高视频下载速率等方式来优化视频质量，以避免视频的卡顿，而不用以改变视频的格式，保证了视频的质量，提高了用户的体验。
本发明实施例提供的视频优化方法，通过网络设备向UE发送第一指示信息，使得UE可以根据该第一指示信息将UE的视频MOS发送给网络设备，从而使得网络设备可以获知UE的视频MOS，进而通过该视频MOS所表征的当前的视频质量等级，及时的获知用户在通过UE使用视频业务时的视频质量和用户体验，进而使得网络设备可以在视频质量较差，即用户体验较差时，能够从根本上优化视频质量，以避免视频的卡顿，保证了视频的质量，提高了用户的体验。
图3为本发明实施例提供的视频优化方法实施例二的信令流程图，本实 施例涉及的是网络设备接收到UE发送的视频MOS之后，如何根据该视频MOS进行视频优化的具体过程。如图3所示，在上述S105之后，该方法包括如下步骤：
S201、网络设备向UE发送最小化路测(Minimization of drive tests，MDT)测量控制信息。
具体的，当网络设备根据视频MOS所表征的当前的视频质量等级，确定当前的视频质量较差时，网络设备可以向UE发送MDT测量控制信息，以指示UE向网络设备发送UE的MDT测量报告，该MDT测量报告可以用于向网络设备指示UE当前的空口信息。
S202、UE接收MDT测量控制信息。
S203、UE根据该MDT测量控制信息，获取MDT测量报告。
具体的，UE在接收到MDT测量控制信息之后，可以启动MDT测量，以测量UE当前的空口信息，该空口信息例如可以包括：UE驻留的小区标识信息、驻留小区的信号质量、UE的位置信息、MDT测量发生的时刻和收到测量控制信息的时间差等信息中的一个或者多个，并将所测量的空口信息生成MDT测量报告。
S204、UE向网络设备发送MDT测量报告。
S205、网络设备接收MDT测量报告。
具体的，网络设备在接收到UE发送的MDT测量报告之后，就可以根据该MDT测量报告中的空口信息，确定视频质量差是否与UE当前所处的位置和UE当前的信号质量有关，若此时UE当前处于小区的边缘位置且UE当前的信号质量较差时，则说明视频质量较差的原因是因为UE的信号质量较差，此时，网络设备可以进一步地通过提高UE的信号质量的方式来对UE进行视频优化，以避免视频的卡顿，提升用户的体验。若此时UE当前处于小区的核心位置且UE当前的信号质量很好时，则说明视频质量差与UE所处的位置无关，而是由核心网的拥塞所导致的，因此，网络设备就可以进一步地通过核心网调整核心网侧的网络资源的方式来进行视频优化，以避免视频的卡顿，提升用户的体验。
本发明实施例提供的视频优化方法，网络设备在接收到UE发送的视频MOS之后，可以进一步的通过指示UE进行MDT路测的方式，获取UE当 前的MDT路测报告，从而使得网络设备可以根据该MDT路测报告，确定UE的视频质量差的原因，进而使得网络设备可以根据视频质量差的原因针对性的进行视频优化，以避免视频出现卡顿的情况，保证了视频的质量，提高了用户体验。
在本发明的另一种实现方式中，网络设备还可以通过如下方式进行视频优化，即网络设备直接根据视频MOS对当前视频占用的网络资源进行控制。可选的，网络设备可以通过接入控制机制来减少或暂停其他UE(这里所说的UE可以为普通用户所使用的UE，也可以为机器类型通讯(Machine Type Communication，简称：MTC)的UE)接入网络中，以保证当前网络中正在使用视频业务的UE的网络资源的占有率，其中，这里所说的接入控制机制例如可以为接入类控制(Access Class Barring，简称：AC Barring)、扩展接入控制(Extended Access Barring，简称EAB)等。可选的，网络设备还可以通过降低接入网络中的非视频业务的UE的网络资源调度优先级，或者释放非视频业务的UE的RRC连接的方式，来保证当前网络中正在使用视频业务的UE的网络资源的占有率，从而避免正在使用视频业务的UE上的视频出现卡顿的情况，进而保证了视频的质量，提高了用户体验。
本发明实施例提供的视频优化方法，网络设备在接收到UE发送的视频MOS之后，可以进一步的通过减少接入网络中的UE的数量，以保证正在使用视频业务的UE的网络资源的占用率，从而避免正在使用视频业务的UE上的视频出现卡顿的情况，保证了视频的质量，提高了用户体验。
进一步地，在上述实施例的基础上，本实施例三涉及的是网络设备在向UE发送第一指示信息之前，接收UE发送的能力指示信息具体过程，则在上述S101之前，该方法还可以包括如下步骤：网络设备接收UE发送的能力指示信息，该能力指示信息用于向网络设备指示UE具有向网络设备发送视频MOS的能力。通过这种方式，使得网络设备在向UE发送第一指示信息之前，可以通过所接收到的UE发送的能力指示信息，确定UE是否具有向网络设备发送视频MOS的能力。当确定UE具有向网络设备发送视频MOS的能力且UE在使用视频业务时，网络设备才会向UE发送第一指示信息，提高了网络设备获取UE的视频MOS的效率，也节省了网络设备的空口开销。
进一步地，在上述实施例的基础上，在本实施例四中，上述第一指示信 息还包括上报条件参数，该上报条件参数用于指示UE向网络设备发送视频MOS的方式，本实施例四涉及的是上述UE如何根据第一指示信息中携带的上报条件参数，向网络设备发送UE的视频MOS的具体过程，则上述S104具体可以有如下三种实现方式：
第一种实现方式：上述上报条件参数为上报周期时，上报条件参数具体用于指示UE按照上报周期向网络设备发送视频MOS。
具体的，当上述上报条件参数为上报周期时，UE可以在接收到第一指示信息之后，按照上报周期，周期性的持续向网络设备发送视频MOS。示例性的，以上报周期为5秒为例，则上述UE在接收到第一指示信息之后，UE就会每隔5秒向网络设备发送一次UE的视频MOS。
第二种实现方式：上述上报条件参数为上报门限时，上报条件参数具体用于指示UE在视频MOS小于上报门限时，向网络设备发送视频MOS。
具体的，当上述视频MOS为视频MOS的分数时，该上报门限可以为视频MOS的一个分数，该分数可以为用户所界定的视频质量差的一个分数，以视频MOS的分数为1至5为例，则上报门限例如可以为3。当上述视频MOS为视频MOS的参数的值时，该上报门限可以为视频MOS参数中的任一视频MOS参数的门限值，该参数的门限值可以为用户所界定的视频质量差的一个门限值。以视频MOS的参数包括视频分辨率、视频比特率、视频编码、视频编码简介、初始缓冲时延、卡顿比例为例，则上述上报门限可以为卡顿比例的门限值，或者初始缓冲时延的门限值，具体可以根据用户的需求确定。
通过这种方式，使得UE可以在视频质量较差时，才会向网络设备发送UE的视频MOS，从而使得网络设备在接收到该视频MOS之后，就可以根据该视频MOS，执行相应的视频优化，提高了网络设备进行视频优化的效率。
第三种实现方式：上报条件参数为上报门限和第一时长时，上报条件参数具体用于指示UE在视频MOS小于上报门限、且视频MOS小于上报门限的状态的持续时间大于或者等于第一时长时，向网络设备发送视频MOS。
具体的，以上述视频MOS为视频MOS的分数为例，假定上述上报门限为3，第一时长为10秒，则在UE接收到第一指示信息之后，当UE根据该第一指示信息中的上报参数确定视频MOS的分数小于3的时长大于或等于10秒时，UE就会立刻向网络设备发送视频MOS。通过这种方式，可以使得 UE仅在视频质量变差持续一段时间后，才会向网络设备发送UE的视频MOS，从而使得网络设备在接收到该视频MOS之后，就可以根据该视频MOS，执行相应的视频优化，提高了网络设备进行视频优化的效率。
本发明实施例提供的视频优化方法，通过网络设备向UE发送第一指示信息，使得UE可以根据该第一指示信息将UE的视频MOS发送给网络设备，从而使得网络设备可以获知UE的视频MOS，进而通过该视频MOS所表征的当前的视频质量等级，及时的获知用户在通过UE使用视频业务时的视频质量和用户体验，进而使得网络设备可以在视频质量较差，即用户体验较差时，能够从根本上优化视频质量，以避免视频的卡顿，保证了视频的质量，提高了用户的体验。

下面结合图10对手机的各个构成部件进行具体的介绍：
RF电路1110可用于收发信息或通话过程中，信号的接收和发送，特别地，将基站的下行信息接收后，给处理器1180处理；另外，将上行的数据发送给基站。通常，RF电路包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器(Low Noise Amplifier，LNA)、双工器等。此外，RF电路1110还可以通过无线通信与网络和其他设备通信。上述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统(Global System of Mobile communication，GSM)、通用分组无线服务(General Packet Radio Service，GPRS)、码分多址(Code Division Multiple Access，CDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、长期演进(Long Term Evolution,LTE))、电子邮件、短消息服务(Short Messaging Service，SMS)等。

WiFi属于短距离无线传输技术，手机通过WiFi模块1170可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图10示出了WiFi模块1170，但是可以理解的是，其并不属于手机的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器1180是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器1120内的软件程序和/或模块，以及调用存储在存储器1120内的数据，执行手机的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器1180可包括一个或多个处理单元；优选的，处理器1180可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器1180中。
