一种网络切换方法及装置
相关申请的交叉引用
本申请要求在2020年12月15日提交中国专利局、申请号为202011484776.7、申请名称为“一种网络切换方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种网络切换方法及装置。
背景技术
随着无线网络及蜂窝网络的快速发展以及终端设备的大量普及，终端在运动过程中涉及的网络连接与切换变得十分常见。如何保证在网络切换过程中，终端上运行业务的体验维持不变显得尤为重要。
网络切换场景可分为无线保真(wireless fidelity，WIFI)/WIFI切换，WIFI/蜂窝切换，蜂窝/WIFI切换，无线局域网(wireless local area network，WLAN)漫游和蜂窝漫游。其中WIFI/WIFI、WIFI/蜂窝、蜂窝/WIFI切换由于会引起IP变化、业务重建，在现网中造成的业务问题最大。
以WIFI/WIFI切换为例，传统网络切换方法在连接WIFI信号消失时，会切换到新WIFI上。在切换到新WIFI时，终端重新扫描WIFI信号，重新鉴权连接，因为IP地址变化，业务层也需重新建立连接。在旧信号消失到连接上新信号的过程中，由于信号较弱以及重新连接会导致业务体验下降甚至业务中断。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
以下，先对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)客观质量平均意见分(mean opinion score，MOS)：衡量通信系统语音质量的重要指标。通常采用1-5分制，分数越高代表质量越好，可以通过大数据拟合出公式客观量化质量，公式的输入可以为音视频引擎层统计的码率、帧率、分辨率等参数。
2)卡顿时长：音视频引擎层统计解码器前后两帧出帧间隔，单位可以为ms，对应实时音视频业务就是语音或画面卡住不动的时长。
3)缓存参数：缓存队列的长度。缓存队列是一种接收端抗抖动的方法，通过将收包放入队列中，按时间戳排序，达到抗抖动的目的，但是队列越长时延越大。
4)冗余率：发送端抗丢包的方法，通过将冗余信息放入帧内达到抗丢包的作用。
随着无线网络及蜂窝网络的快速发展以及终端设备的大量普及，终端在运动过程中涉及的网络连接与切换变得十分常见。如何保证在网络切换过程中，终端上运行业务的体验维持不变显得尤为重要。
网络切换场景可分为WIFI/WIFI切换，WIFI/蜂窝切换，蜂窝/WIFI切换，Wlan漫游和蜂窝漫游。其中WIFI/WIFI、WIFI/蜂窝、蜂窝/WIFI切换由于会引起IP变化、业务重建，在现网中造成的业务问题最大。
以WIFI/WIFI切换为例，传统网络切换方法在连接WIFI信号消失时，会切换到新WIFI上。在切换到新WIFI时，终端重新扫描WIFI信号，重新鉴权连接，因为IP地址变化，业务层也需重新建立连接，如图1所示。在旧信号消失到连接上新信号的过程中，由于信号较弱以及重新连接会导致业务体验下降甚至业务中断。
为缩短弱信号时长、减少业务体验下降，一种常用的网络切换方法为：根据当前信号强度与设定阈值进行比较，判断当前是否处于弱信号，如果是，则提前进入切换流程，如图2所示。例如：设定WIFI弱信号的判定阈值为-80dB，则当终端远离旧信号的过程中，一旦终端检测到当前信号<-80dB，则触发切换流程。
但是这种切换方法只能缩短处于弱信号的时间，不能避免新信号重新鉴权连接所带来的业务体验下降。而且设定的阈值一般比较固定，不能随场景动态调整，因此对于不同网络场景的适应性较弱。此外，该切换方法是通过对终端硬件层面物理连接方式的切换来实现，切换时会影响终端上所有运行的业务。
基于此，本申请提供一种网络切换方法及装置，用以解决现有技术中终端设备在网络切换过程中业务体验下降的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。

S701，电子设备获取体验特质信息，体验特质信息包括一个或多个用于指示第一业务的业务质量的参数。
一种实现方式中，电子设备可以在音视频引擎层统计第一业务的体验特质信息。具体的，可以是电子设备的音视频引擎层的QOE统计模块统计第一业务的体验特质信息。
示例性的，体验特质信息可以包括如下参数中至少一项：客观质量MOS分、拥塞时长、卡顿时长、编码码率、连续丢包数、分辨率。此外，体验特质信息还可以包括丢包率、丢包数、抖动值、时延等参数。其中，连续丢包数可以为应用层数据包的连续丢包数。
一种可能的实施方式中，音视频引擎层可以周期性的统计第一业务的体验特质信息，并发送给多连接管理层。通过这种方式，多连接管理层可以及时感知业务质量。
S702，电子设备获取第一通信连接的服务质量信息，第一通信连接的服务质量信息包括一个或多个用于指示第一通信连接的通信质量的参数，第一通信连接用于传输第一业务的数据。
一种实现方式中，电子设备可以在多连接管理层统计第一通信连接的服务质量信息。

其中，第二通信连接可以满足预设条件，例如，预设条件可以为：第二通信连接的服务质量信息满足服务质量要求，或者，第二通信连接的服务质量信息指示的通信质量比第一通信连接的服务质量信息指示的通信质量高。第二通信连接的服务质量信息包括一个或多个用于指示第二通信连接的通信质量的参数。
可选的，电子设备的多连接管理层在将第一业务由第一通信连接切换到第二通信连接之前，可以对包括第二通信连接在内的多个通信连接发送探测信号，确定该多个通信连接的服务质量信息。在确定第二通信连接的服务质量信息满足服务质量要求时，确定将第一业务由第一通信连接切换到第二通信连接。或者，在确定第二通信连接的服务质量比第一通信连接的服务质量好时，确定将第一业务由第一通信连接切换到第二通信连接。
本申请实施例中电子设备可以结合更符合用户业务体验的音视频引擎层QOE信息，使得网络切换可以更及时、更贴近用户业务体验。相比于现有技术，本申请实施例可以在一定程度上保证实时音视频业务的不掉话，例如通过本申请实施例可以使卡顿时长可以减少90％。
下面对体验特质信息是否满足体验特质要求的判定方法进行示例性说明。
一种示例性说明中，体验特质信息不满足体验特质要求，可以指：体验特质信息中至少一个参数不满足对应的判定条件。体验特质信息满足体验特质要求，可以指：体验特质信息中的所有参数均满足对应的判定条件。
其中，若参数的值与第一业务的业务质量正相关，即第一业务的业务质量越好，该参数的值越大，则参数不满足对应的判定条件指参数小于对应的阈值，参数满足对应的判定条件指参数不小于对应的阈值。例如客观质量MOS分与第一业务的业务质量正相关，第一业务的业务质量越好，客观质量MOS分越高，则客观质量MOS分不满足对应的判定条件指客观质量MOS分小于对应阈值，客观质量MOS分满足对应的判定条件指客观质量MOS分不小于对应阈值。
若参数的值与第一业务的业务质量负相关，即第一业务的业务质量越好，该参数的值越小，则参数不满足对应的判定条件指参数大于对应的阈值，参数满足对应的判定条件指参数不大于对应的阈值。例如时延与第一业务的业务质量正相关，第一业务的业务质量越好，时延越低，则时延不满足对应的判定条件指时延大于对应阈值，时延满足对应的判定条件指时延不大于对应阈值。
例如，假设体验特质信息包括客观质量MOS分、拥塞时长和卡顿时长。当客观质量MOS分<2或拥塞时长>2或卡顿时长>2s时，确定体验特质信息不满足体验特质要求。当客观质量MOS分＞2且拥塞时长＜2且卡顿时长＜2s时，确定体验特质信息满足体验特质要求。
需要说明的是，本申请实施例中各参数的阈值仅是举例说明，并不对阈值的大小进行具体限定。在具体实施中，各参数的阈值可以预配置的，也可以是服务器侧指示的，也可以通过其他方式确定的，这里不做具体限定。此外，同一个参数的阈值在不同场景中或者不同业务时可以相同也可以不同。
另一种示例性说明中，体验特质信息不满足体验特质要求，可以指：体验特质信息中 不满足对应的判定条件的参数超过预设值。体验特质信息满足体验特质要求，可以指：体验特质信息中不满足对应的判定条件的参数不超过预设值。

其中，若参数的值与第一通信连接的通信质量正相关，即第一通信连接的通信质量越好，该参数的值越大，则参数不满足对应的判定条件指参数小于对应的阈值，例如信号强度与第一通信连接的通信质量正相关，第一通信连接的通信质量越好，信号强度越高，则信号强度不满足对应的判定条件指信号强度小于对应阈值，信号强度满足对应的判定条件指信号强度不小于对应阈值。
若参数的值与第一通信连接的通信质量负相关，即第一通信连接的通信质量越好，该参数的值越小，则参数不满足对应的判定条件指参数大于对应的阈值，例如时延与第一通信连接的通信质量正相关，第一通信连接的通信质量越好，时延越低，则时延不满足对应的判定条件指时延大于对应阈值，时延满足对应的判定条件指时延不大于对应阈值。
例如，假设第一通信连接的服务质量信息包括丢包率和时延。当丢包率>50％或时延>1s时，确定第一通信连接的服务质量信息不满足服务质量要求。当丢包率＜50％且时延＜1s时，确定第一通信连接的服务质量信息满足服务质量要求。
另一种示例性说明中，第一通信连接的服务质量信息不满足服务质量要求，可以指：服务质量信息中不满足对应的判定条件的参数超过预设值。
一种实现方式中，电子设备的音视频引擎层可以向多连接管理层发送体验特质信息。具体的，可以是电子设备的音视频引擎层的QOE统计模块向多连接管理层发送体验特质信息。电子设备的多连接管理层判断体验特质信息是否满足体验特质要求，以及第一通信连接的服务质量信息是否满足服务质量要求。电子设备的多连接管理层在体验特质信息不满足体验特质要求，和/或，第一通信连接的服务质量信息不满足服务质量要求时，将第一业务由第一通信连接切换到第二通信连接。电子设备的多连接管理层在体验特质信息满足体验特质要求，且第一通信连接的服务质量信息满足服务质量要求时，继续在第一通信连接上传输第一业务的数据。

另一种实现方式中，电子设备的音视频引擎层可以判断体验特质信息是否满足体验特质要求，并在体验特质信息不满足体验特质要求向电子设备的多连接管理层发送切换指示。具体的，可以是电子设备的音视频引擎层的QOE统计模块判断体验特质信息是否满足体验特质要求，并在体验特质信息不满足体验特质要求向电子设备的多连接管理层发送切换指示。电子设备的多连接管理层判断第一通信连接的服务质量信息不满足服务质量要求。电子设备的多连接管理层在接收到切换指示，和/或，第一通信连接的服务质量信息不满足服务质量要求时，将第一业务由第一通信连接切换到第二通信连接。电子设备的多连接管理层在未接收到切换指示，且第一通信连接的服务质量信息满足服务质量要求时，继续在第一通信连接上传输第一业务的数据。
示例性的，如图9所示。网络切换过程可以包括：
S901，音视频引擎层周期性的统计第一业务的体验特质信息，其中，体验特质信息包括客观质量MOS分、拥塞时长和卡顿时长。执行S902。
S902，音视频引擎层判断第一业务的体验特质信息是否未满足体验特质要求(即客观质量MOS分<2或拥塞时长>2或卡顿时长>2s)。若是，执行步骤S903。若否，音视频引擎层继续周期性统计第一业务的体验特质信息。

S910，多连接管理层在该多个通信连接中选择通信质量最优的第二通信连接进行切换。
又一种实现方式中，电子设备的音视频引擎层也可以判断体验特质信息是否满足体验特质要求，并向电子设备的多连接管理层发送判定结果，其中，判定结果指示体验特质信息满足体验特质要求或者体验特质信息不满足体验特质要求。电子设备的多连接管理层判断第一通信连接的服务质量信息不满足服务质量要求。电子设备的多连接管理层在电子设备的音视频引擎层发送的判定结果指示体验特质信息不满足体验特质要求，和/或，第一通信连接的服务质量信息不满足服务质量要求时，将第一业务由第一通信连接切换到第二通 信连接。电子设备的多连接管理层在电子设备的音视频引擎层发送的判定结果指示体验特质信息满足体验特质要求，且第一通信连接的服务质量信息满足服务质量要求时，继续在第一通信连接上传输第一业务的数据。
在一些可能的实施方式中，电子设备在将第一业务由第一通信连接切换到第二通信连接之后，还可以根据第二通信连接的服务质量信息调整第一业务的播放参数，播放参数包括如下参数中至少一项：码率、分辨率、缓存参数、冗余率。其中，调整第一业务的播放参数可以影响第一业务的体验特质信息的参数值。举例说明，提高第一业务的码率可以提高体验特质信息中的MOS分、编码码率以及分辨率，还可以减少体验特质信息中的拥塞时长、卡顿时长、连续丢包数。提高第一业务的分辨率可以提高体验特质信息中的MOS分。降低第一业务的缓存参数可以提高体验特质信息中的MOS分。降低第一业务的冗余率可以提高体验特质信息中的编码码率、分辨率，还可以减少体验特质信息中的拥塞时长。
一种可能的实施方式中，电子设备调整第一业务的播放参数时可以执行如下至少一项：提高码率、提高分辨率、降低缓存参数、降低冗余率。当电子设备处于弱网下也就是第一通信连接的通信质量较差，且还未进行网络切换前，音视频引擎层的网络自适应模块根据感知到网络状态变化，例如通过统计第一业务的体验特质信息感知网络状态变化，并实时下调码率，引起业务清晰度下降。当多连接管理层进行将第一业务由第一通信连接切换到第二通信连接之后，及时将第二通信连接的服务质量信息反馈给音视频引擎层，音视频引擎层的网络自适应模块根据第二通信连接的服务质量信息上调码率。
另一种可能的实施方式中，电子设备在根据第二通信连接的服务质量信息调整第一业务的播放参数时，根据第二通信连接的服务质量信息确定第一业务的第一参数的调整值，并根据调整值调整将第一业务的第一参数，其中，第一参数为码率或者分辨率或者缓存参数或者冗余率。例如，电子设备根据第二通信连接的服务质量信息确定码率的调整值，并根据该调整值提高码率。又例如，电子设备根据第二通信连接的服务质量信息确定冗余率的调整值，并根据该调整值降低冗余率。
当电子设备处于弱网下也就是第一通信连接的通信质量较差，且还未进行网络切换前，音视频引擎层的网络自适应模块根据感知到网络状态变化，例如通过统计第一业务的体验特质信息感知网络状态变化，并实时下调码率，引起业务清晰度下降。当多连接管理层进行将第一业务由第一通信连接切换到第二通信连接之后，及时将第二通信连接的服务质量信息反馈给音视频引擎层，音视频引擎层的网络自适应模块根据第二通信连接的服务质量信息上调码率。并根据第二通信连接的服务质量信息决策上调幅度，如第二通信连接的丢包率<20％且时延<0.5s，则将码率上调100％，否则若丢包率<50％且时延<1s，则将码率上调50％。上述方式中，通过音视频引擎层和多连接管理层联动的方式调整码率，可以提升业务清晰度，从而可以避免网络自适应模块因切换前后的网络状态变动而长时间决策在低码率下运行，进而可以提升用户体验。
一种实现方式中，电子设备的多连接管理层在将第一业务由第一通信连接切换到第二通信连接之后，还可以统计第二通信连接的服务质量信息。电子设备的多连接管理层向电子设备的音视频引擎层发送第二通信连接的服务质量信息和切换信息，该切换信息用于指示第一业务由第一通信连接切换到第二通信连接。电子设备的音视频引擎层可以根据第二通信连接的服务质量信息和切换信息调整第一业务的播放参数。
示例性的，如图10所示，音视频引擎层周期性统计第一业务的体验特质信息，并发 送给多连接管理层。多连接管理层统计第一通信连接的服务质量信息，并根据第一业务的体验特质信息以及第一通信连接的服务质量信息确定将第一业务由第一通信连接切换到第二通信连接。多连接管理层向音视频引擎层发送第二通信连接的服务质量信息。音视频引擎层根据第二通信连接的服务质量信息调整第一业务的播放参数。
具体的，电子设备的多连接管理层可以向电子设备的音视频引擎层的网络自适应模块发送第二通信连接的服务质量信息。电子设备的音视频引擎层的网络自适应模块根据第二通信连接的服务质量信息调整第一业务的播放参数。
通过上述方式，使得网络切换前后的实时音视频业务清晰度可以得到提升。相比现有技术方案，本申请实施例在网络切换场景中可以提升实时音视频业务清晰度，例如可以使得实时音视频业务清晰度提升30％。

S1110，音视频引擎层根据第二通信连接的服务质量信息调整第一业务的码率。
例如，若第二通信连接的丢包率<20％且时延<0.5s，则将码率上调100％，若丢包率<50％且时延<1s，则将码率上调50％。
示例性，如图12所示。另一种网络切换过程可以包括：
