具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书、权利要求书或上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
还应当理解，在本申请实施例说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请实施例的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实 施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
OTT是“Over The Top”的缩写，OTT Service通常指一种架构在网络运营商提供的网络之上的服务业务，如Skype，Google Voice，微信电话等。它可以是网络运营商提供，也可以是第三方提供。目前第三方提供的更多，网络运营商由于OTT业务的兴起，日益被管道化。它被称为OTT服务是因为它运营在用户已经获得的网络之上而且不需要网络运营商额外的技术支撑。例如，OTT网络电话，可让人们免费高清晰与其他用户语音对话，也可以拨打国内国际电话。目前运营商网络中VOLTE，VONR语音业务优先级高，一旦发起或者接收相关业务，OTT呼叫业务被无条件打断，影响OTT呼叫业务体验。
而当前OTT呼叫业务中的语音通话和视频通话也同样重要，而传统方式通过终端侧自主实现，对于不同的终端需要单独预配置一套对应的策略，大大增加了终端的开发、测试和运维的成本，因此目前需提出一种方法策略，能够适应不同型号类型的终端实现保护OTT的正常呼叫业务，避免OTT呼叫时被中断。
为了解决上述技术问题，本申请实施例提供了一种OTT呼叫业务的控制方法、控制器以及存储介质，其中，该呼叫业务包括语音或者视频电话，主叫方式和被叫方式，本方案从网络侧提高终端的OTT呼叫业务的优先级，降低不同终端保障OTT呼叫业务的策略开发成本。其中，该OTT呼叫业务的控制方法的步骤为：终端向网络侧发送OTT呼叫业务保障请求，网络侧获取来自终端的OTT呼叫业务保障请求，并根据OTT呼叫业务保障请求，向终端发送优先级修改指令，终端响应于优先级修改指令，修改OTT呼叫业务的优先级，以使得OTT呼叫业务的优先级高于语音呼叫业务的优先级。将OTT呼叫业务的优先级修改至高于或者等于语音呼叫业务的优先级，使得正在进行OTT呼叫业务时能够不被语音呼叫业务的寻呼所打断，或者不会在正在进行语音呼叫业务时自动挂断OTT呼叫业务的寻呼，保障OTT呼叫业务过程和OTT呼叫业务连续性，例如，支持OTT业务过程中不被VOLTE，VONR等SIP业务中断，且从网络侧提高终端的OTT呼叫业务的优先级，降低不同终端保障OTT呼叫业务的策略开发成本。本申请的控制方法适用于通信系统内，系统间和MR-DC等系统。
下面结合附图，对本申请实施例作进一步阐述。
参照图1，图1是本申请一个实施例提供的OTT呼叫业务的控制方法的流程图，本申请提供了一种OTT呼叫业务的控制方法，应用于网络侧，可以包括但不限于包括步骤S110、步骤S120：
步骤S110：获取来自终端的OTT呼叫业务保障请求；
在一实施例中，终端为了保护OTT呼叫业务的正常服务，则在OTT业务保护开启过程中，终端通过NAS(Non-access stratum，非接入层)上报OTT呼叫保障请求信元指示给核心网(EPC/5GC)，其中，核心网为网络侧的其中一部分， 告知OTT业务过程高优先级，或者和语音相同优先级，期间不能被VOLTE(QCI1/QCI2)，VONR(5QI1/5QI2)业务中断，或者提供用户一种选项，让用户主动选择使用哪种方式。
步骤S120：根据OTT呼叫业务保障请求，向终端发送优先级修改指令，以使得终端的OTT呼叫业务的优先级高于或等于语音呼叫业务的优先级。
网络侧根据接收到的OTT呼叫业务保障请求，主动向终端发送优先级修改指令，以使得终端的OTT呼叫业务的优先级高于语音呼叫业务的优先级，即提高OTT呼叫业务过程中的QCI/5QI优先级。例如，微信通话时，终端与网络建议5QI9无线承载通道，网络侧根据终端发送的OTT呼叫业务保障请求，提高主动发起关于5QI9的优先级修改指令，使得5QI9的优先级大于5QI1的优先级，其中，5QI1为VONR通信的无线承载通道，如5QI1默认是20，将5QI9设置为19，其中，取值越小，优先级越高。将OTT呼叫业务的优先级修改至高于或者等于语音呼叫业务的优先级使得正在进行OTT呼叫业务时能够不被语音呼叫业务的寻呼所打断，或者不会在正在进行语音呼叫业务时自动挂断OTT呼叫业务的寻呼，保障OTT呼叫业务过程和OTT呼叫业务连续性。
同时，从网络侧提高终端的OTT呼叫业务的优先级，不需要对不同的终端进行单独预配置一套对应提高OTT呼叫业务优先级的策略，降低不同终端保障OTT呼叫业务的策略开发成本。终端侧优化配置，收到网络侧修改指示后，可以做两方面优化，1).提供OTT呼叫业务和传统呼叫业务选项，供用户主动选择。2).在OTT业务优先级高于传统语音业务，则主动发送友好短信提示。
参照图2，图2是本申请另一实施例提供的OTT呼叫业务的控制方法的流程图；本申请提供的OTT呼叫业务优先级的控制方法还包括但不仅限于以下步骤：
步骤S210：当终端的OTT呼叫业务结束后，向终端发送优先级恢复指令，以使得终端的OTT呼叫业务和语音呼叫业务的优先级恢复到默认值。
在终端的OTT呼叫业务结束后，为了终端后续的正常语音呼叫业务，需要将终端的OTT呼叫业务和语音呼叫业务的优先值恢复到默认值，避免终端需要一直保持OTT呼叫业务的优先所造成的资源占用。
另外，参照图3，图3时本申请另一实施例提供的OTT呼叫业务的控制方法的流程图，本申请还提供了一种应用于终端的OTT呼叫业务控制方法，可以包括但不限于包括步骤S310、步骤S320：
步骤S310：向网络侧发送OTT呼叫业务保障请求，以使网络侧根据OTT呼叫业务保障请求发送优先级修改指令；
在一实施例中，终端为了保护OTT呼叫业务的正常服务，则在OTT业务保护开启过程中，终端通过NAS上报OTT呼叫保障请求信元指示给核心网(EPC/5GC)，其中，核心网为网络侧的其中一部分，告知OTT业务过程高优先级，期间不能被VOLTE(QCI1/QCI2)，VONR(5QI1/5QI2)业务中断。
需要说明的是，终端用户可以根据实际需求，预设OTT业务保护时间段，该 OTT业务保护时间段为实际时间段，例如，该终端用户需要在早上9点到11点使用微信通话参加会议，则该终端用户可将OTT业务保护时间段设置为9点到11点；当然，终端用户还可以将OTT业务保护时间段设为全时段，即一天24小时都开启OTT业务保护时间段，对于具体OTT业务保护时间段的方式，在本申请不作限制。
步骤S320：响应于优先级修改指令，修改OTT呼叫业务的优先级，以使得OTT呼叫业务的优先级高于或等于语音呼叫业务的优先级。
终端相应于由网络侧发送的优先级修改指令，根据优先级修改指令将OTT呼叫业务的优先级修改至高于或者等于语音呼叫业务的优先级，即提高OTT呼叫业务过程中的QCI/5QI优先级。例如，微信通话时，终端与网络建立5QI9无线承载通道，网络侧根据终端发送的OTT呼叫业务保障请求，提高主动发起关于5QI9的优先级修改指令，使得5QI9的优先级大于5QI1的优先级，其中，5QI1为VONR通信的无线承载通道。将OTT呼叫业务的优先级修改至高于或者等于语音呼叫业务的优先级，如5QI1默认是20，将5QI9设置为19，其中，取值越小，优先级越高，使得正在进行OTT呼叫业务时能够不被语音呼叫业务的寻呼所打断，或者不会在正在进行语音呼叫业务时自动挂断OTT呼叫业务的寻呼，保障OTT呼叫业务过程和OTT呼叫业务连续性。
同时，从网络侧提高终端的OTT呼叫业务的优先级，不需要对不同的终端进行单独预配置一套对应提高OTT呼叫业务优先级的策略，降低不同终端保障OTT呼叫业务的策略开发成本。
本申请还包含了OTT呼叫业务过程，主动发起传统语音业务请求场景，下面对不同的场景进行一一赘述。
参照图4，图4是本申请另一实施例提供的OTT呼叫业务的控制方法的流程图；在终端发起OTT呼叫业务的情况下，在步骤S320之后，本申请提供的OTT呼叫业务的控制方法，还包括但不仅限于以下步骤：
步骤S410：接收语音呼叫业务的寻呼信息；
步骤S420：保持OTT呼叫业务。
其中，该语音呼叫业务包括主动拨打电话方式以及被动拨打电话方式等，终端用户可设置免打扰模式，即当在终端进行OTT呼叫业务时，自动拒绝其他呼叫业务的寻呼信息。在一实施例中，终端用户发起OTT呼叫业务时，此时，终端的OTT呼叫业务的优先级比语音呼叫业务的优先级要高，在OTT呼叫业务的过程中收到语音呼叫业务的寻呼信息，对该寻呼信息不作应答，并保持原有正在进行的OTT呼叫业务，保障OTT呼叫业务过程和OTT呼叫业务连续性。同时，当终端自动拒绝了语音呼叫业务的寻呼信息时，可通过短信或者语音的方式告知该语音呼叫业务的呼叫人，提高双方的使用体验。
在一实施例中，网络侧包括NR基站和5GC核心网，终端发起了微信语音通话(OTT呼叫业务)，同时终端设置了OTT呼叫业务保障功能并通过UL  Information Transfer(网络中上行消息传输)携带OTT呼叫业务保障请求的指示给核心网5GC。网络给微信语音通话建立了5QI9无线承载。核心网收到OTT呼叫业务保障请求的指示后，主动给终端发起5QI9的业务优先级修改，修改优先级大于5QI1优先级。(比如5QI1默认是20，5QI9设置为19，取值越小，优先级越高)。若终端此时收到了VONR/EPS Fallback业务(语音呼叫业务)，核心网下发对应的语音呼叫业务的寻呼信息通过NR发送至终端。终端收到寻呼信息后，对比业务优先级。网络侧下发VONR/EPS Fallback振铃提示给UE，让用户选择接听语音呼叫业务，还是维持OTT呼叫业务过程，同时在选择继续维持OTT呼叫业务的时候，对语音呼叫业务的发起方提供自动短信回复。同时，如果该终端设置了免打扰模式，终端在进行微信语音通话时，将自动挂断在微信语音通话期间的语音呼叫业务，并对语音呼叫业务的发起方提供自动短信回复。
参照图5，图5是本申请另一实施例提供的OTT呼叫业务的控制方法的流程图；在步骤S320之后，本申请提供的OTT呼叫业务的控制方法，还包括但不仅限于以下步骤：
步骤S510：同时接收到OTT呼叫业务的寻呼信息和语音呼叫业务的寻呼信息；
步骤S520：根据OTT呼叫业务的寻呼信息和语音呼叫业务的寻呼信息生成第一寻呼选择信息；
步骤S530：接收根据第一寻呼选择信息所得到的第一选择结果信息；
步骤S540：根据第一选择结果信息接入语音呼叫业务，或者接入OTT呼叫业务。
当终端同时接收到OTT呼叫业务的寻呼信息和语音呼叫业务的寻呼信息，因OTT呼叫业务的优先级被提高，不会直接被语音呼叫业务打断，然而，在未接听OTT呼叫业务前且同时收到OTT呼叫业务的寻呼信息和语音呼叫业务的寻呼信息，为了避免客户错过重要的电话，则并未直接对语音呼叫业务的寻呼信息进行挂断，而是根据OTT呼叫业务的寻呼信息和语音呼叫业务的寻呼信息生成第一寻呼选择信息，第一寻呼选择信息用于提供给用户选择接听OTT呼叫业务对应的寻呼信息还是接听语音呼叫业务的寻呼信息。用户在终端选择对应的寻呼信息后，终端将该结果生成第一选择结果信息，根据第一选择结果信息，接入语音呼叫业务或者接入OTT呼叫业务，通过该方法能够不会自动挂断OTT呼叫业务的寻呼，避免错过重要的寻呼。
参照图6，图6是本申请另一实施例提供的OTT呼叫业务的控制方法的流程图；在步骤S540中，包括但不仅限于以下步骤：
步骤S610：根据第一选择结果信息生成第一通话业务决定信息；其中，第一通话业务决定信息为接入语音呼叫业务，或者接入OTT呼叫业务；
步骤S620：向网络侧发送第一通话业务决定信息。
通过将用户选择的第一选择结果信息生成第一通话业务决定消息，将第一通 话业务决定信息发送至网络侧，从而建立对应的通话承载通道。
参照图7，图7是本申请另一实施例提供的OTT呼叫业务的控制方法的流程图；在处于语音呼叫业务的情况下，在步骤S320之后，本申请提供的OTT呼叫业务的控制方法，还包括但不仅限于以下步骤：
步骤S710：接收到OTT呼叫业务的寻呼信息；
步骤S720：根据OTT呼叫业务的寻呼信息生成第二寻呼选择信息；
步骤S730：接收根据第二寻呼选择信息所得到的第二选择结果信息；
步骤S740：根据第二选择结果信息保持语音呼叫业务，或者中断语音呼叫业务并接入OTT呼叫业务。
终端处于语音呼叫业务的情况下，当接收到OTT呼叫业务的寻呼信息时，由于已经预先将OTT呼叫业务的优先级设置为高于语音呼叫业务的优先级，因此OTT呼叫业务的寻呼信息不会直接被挂断，终端根据OTT呼叫业务的寻呼信息生成第二寻呼选择信息，其中第二寻呼选择信息用于提供用户选择继续保持语音呼叫业务或者是中断语音呼叫业务并接听OTT呼叫业务，用户根据第二寻呼选择信息生成第二选择结果信息，终端接受该第二选择结果信息进行保持语音呼叫业务，或者中断语音呼叫业务并接入OTT呼叫业务。通过该方式能够使得在终端处于语音呼叫业务的情况下，OTT呼叫业务不会直接被中断，提高了对OTT呼叫业务的使用体验。
参照图8，图8是本申请另一实施例提供的OTT呼叫业务的控制方法的流程图；在步骤S740中，包括但不仅限于以下步骤：
步骤S810：根据第二选择结果信息生成第二通话业务决定信息；其中，第二通话业务决定信息为保持语音呼叫业务的决定信息，或者中断语音呼叫业务并接入OTT呼叫业务；
步骤S820：向网络侧发送第二通话业务决定信息。
通过将用户选择的第一选择结果信息生成第一通话业务决定消息，将第一通话业务决定信息发送至网络侧，从而建立对应的通话承载通道。
在一实施例中，终端已经发起了VOLTE/VONR业务(语音呼叫业务)，在该语音呼叫业务保持过程中，终端接受到了微信语音通话(OTT呼叫业务)的寻呼信息，同时终端设置了OTT呼叫业务保障功能，并通过UL Information Transfer携带OTT calling guarantee(OTT呼叫业务保障请求)指示给核心网5GC。网络给微信语音通话建立了5QI9无线承载。核心网收到OTT呼叫业务保障请求的指示后，主动给终端发起5QI9的业务优先级修改，修改优先级大于5QI1优先级。(比如5QI1默认是20，5QI9设置为19，取值越小，优先级越高)。终端收到语音呼叫业务的寻呼消息后，对比OTT呼叫业务和语音呼叫业务的优先级。网络侧让用户选择保持语音呼叫业务，或者中断语音呼叫业务并接入OTT呼叫业务。同时在选择接听OTT业务时，给语音呼叫业务的发起方提供自动挂断短信回复。
参照图9，图9是本申请另一实施例提供的OTT呼叫业务的控制方法的流程图；在步骤S420之后，或在步骤S620中第一通话业务决定信息为接入OTT呼叫业务的情况下之后，或在步骤S820中第二通话业务决定信息为中断语音呼叫业务并接入OTT呼叫业务的情况之后，本申请提供的OTT呼叫业务的控制方法，还包括但不仅限于以下步骤：
步骤S910：响应于来自网络侧的优先级恢复指令，使OTT呼叫业务和语音呼叫业务的优先级恢复到默认值。
在终端的OTT呼叫业务结束后，为了终端后续的正常语音呼叫业务，需要将终端的OTT呼叫业务和语音呼叫业务的优先值恢复到默认值，避免终端需要一直保持OTT呼叫业务的优先所造成的资源占用。
另外，参照图10，图10是本申请一个实施例提供的控制器100的示意图。其中，该控制器100包括：存储器120、处理器110及存储在存储器120上并可在处理器110上运行的计算机程序，其中，处理器110执行计算机程序时实现上述任意一项实施例的OTT呼叫业务的控制方法。
该系统通过终端向网络侧发送OTT呼叫业务保障请求，网络侧获取来自终端的OTT呼叫业务保障请求，并根据OTT呼叫业务保障请求，向终端发送优先级修改指令，终端响应于优先级修改指令，修改OTT呼叫业务的优先级，以使得OTT呼叫业务的优先级高于语音呼叫业务的优先级。将OTT呼叫业务的优先级修改至高于或者等于语音呼叫业务的优先级，使得正在进行OTT呼叫业务时能够不被语音呼叫业务的寻呼所打断，同时不会在正在进行语音呼叫业务时自动挂断OTT呼叫业务的寻呼，保障OTT呼叫业务过程和OTT呼叫业务连续性，且从网络侧提高终端的OTT呼叫业务的优先级，降低不同终端保障OTT呼叫业务的策略开发成本。
参照图10，处理器110和存储器120可以通过总线或其他方式连接。
存储器120作为一种非暂态计算机可读存储介质，可用于存储非暂态软件程序、非暂态性计算机可执行程序以及信号，如本申请实施例中的处理模块对应的程序指令/信号。处理器110通过运行存储在存储器120中的非暂态软件程序、指令以及信号，从而执行各种功能应用以及数据处理，即实现上述方法实施例的OTT呼叫业务的控制方法。
存储器120可以包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需要的应用程序；存储数据区可存储上述OTT呼叫业务的控制方法的相关数据等。此外，存储器120可以包括高速随机存取存储器120，还可以包括非暂态存储器120，例如至少一个磁盘存储器120件、闪存器件、或其他非暂态固态存储器120件。在一些实施例中，存储器120可包括相对于处理器110远程设置的存储器120，这些远程存储器120可以通过网络连接至该处理模块。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
