Description

语音承载注册方法及装置、终端、计算机可读存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及语音承载注册方法、语音承载注册装置、终端和计算机可读存储介质。
背景技术
随着移动网络的发展，5G独立组网SA(StandAlone)网络的普及率大幅上升，但是相比于较为成熟的用于实现4G网络下通话的长期演进语音承载VoLTE(Voice over Long-Term Evolution)技术，目前用于实现5G网络下通话的新空口语音承载VoNR(Voice over New Radio)技术并未被大规模商用，部分5G SA网络并不支持VoNR通话。因此，对于驻留在5G SA网络的终端，如何注册语音承载也实现语音或视频通话业务，是亟待解决的技术问题。
发明内容

图1是根据本公开的实施例示出的一种语音承载注册方法的示意流程图。本实施例所示的语音承载注册方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络侧设备通信，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备，例如基站、核心网等。
如图1所示，所述语音承载注册方法可以包括以下步骤：
在步骤S101中，判断所述终端是否满足预设条件，其中，所述预设条件至少包括所述终端当前驻留网络为5G独立组网SA网络；
在步骤S102中，在所述终端满足预设条件的情况下，切换到非5G SA网络注册语音承载。
在一个实施例中，所述预条件还包括以下至少之一：
所述终端进行IP多媒体子系统IMS承载建立失败的原因包括网络拒绝；
所述终端进行IMS承载建立失败的次数大于或等于预设次数；
所述终端进行IMS无线保真语音承载VoWIFI注册成功；
所述终端处于通话场景。
其中，IP多媒体子系统(IP multimedia subsystem，IMS)是一种用于提供多媒体业务的网络系统，通过将语音业务承载在IP网络上，IMS可以为终端设备提供多种多媒体业务，如语音或视频通话、视频通话等。
长期演进语音承载(Voice over Long-Term Evolution，VoLTE)是一种通过4G网络的接入网和核心网，与IMS系统实现语音业务的方式，可以应用于4G网络和/或5G非独立组网NSA网络。
新空口语音承载(Voice over New Radio，VoNR)是一种通过5G网络的接入网和核心网，与IMS系统实现语音业务的方式，可以应用于5G独立组网SA网络。
无线保真语音承载(Voice over WIFI，VoWIFI)是一种利用无线局域网与IMS系统实现语音业务的方式，可以应用于无线局域网。
在一实施例中，所述非5G SA网络可以包括5G非独立组网NSA网络和/或4G网络，终端在切换到5G NSA网络或者4G网络后可以通过注册非长期演进语音承载VoLTE实现语音或视频通话业务。
在相关技术中，终端在注册到网络后，会向其所注册的网络发送IMS承载建立请求，若IMS承载建立成功，则终端可以在IMS承载的基础上注册语音承载；若IMS承载建立失败，则终端可以接收到网络侧返回的IMS承载建立失败的原因值，并根据接收到的原因值重新向网络侧发起IMS承载建立请求。
当终端驻留在5G SA网络时，若终端需要执行语音或视频通话业务，则需要向5G SA网络发生IMS承载建立请求，并在成功建立的IMS承载的基础上注册新空口语音承载VoNR。
另外，在相关技术中，无线网络语音承载是当前运营商主推的终端电话通信解决方案之一。终端在接入WIFI无线网络的情况下，可以通过VoWIFI进行语音或视频通话业务。
但是，在终端通过VoWIFI进行通话的过程中，终端可能会由于其所接入的WIFI的信号较弱，或者由于用户的移动离开了WIFI信号的覆盖区域，需要从WIFI网络切换到蜂窝网络驻留。而在网络切换的同时，终端所注册的语音承载也需要从VoWIFI切换为与蜂窝网络相对应的语音承载。例如，在终端通过VoWIFI进行通话的过程中，若终端从WIFI网络切换到5G SA网络驻留，则终端需要将其所注册的语音承载从VoWIFI切换到VoNR。
但是，由于VoNR技术并未被大规模商用，终端所驻留的5G SA网络很可能并不支持VoNR。因此，当终端在驻留在5G SA网络时，终端有较大的可能性无法成功注册VoNR，从而完全无法执行语音或视频通话功能，严重影响了用户的正常使用 体验。
根据本实施例，终端可以根据当前驻留网络的网络状态，在确定当前驻留网络为5G SA网络的情况下，终端可以自动切换到非5G SA网络，并通过在非5G SA网络注册长期演进语音承载使得终端能够正常执行语音或视频通话业务。降低终端由于当前驻留的5G SA网络不支持VoNR而无法成功注册语音承载，影响终端执行语音或视频通话业务的概率。
图2是根据本公开的实施例示出的另一种语音承载注册方法的示意图。如图2所示，所述在所述终端满足预设条件的情况下，切换到非5G SA网络注册语音承载，包括：
在步骤S201中，在所述终端当前驻留网络为5G SA网络，且所述终端进行IMS承载建立失败的原因包括网络拒绝，且所述终端进行IMS承载建立失败的次数大于或等于预设次数的情况下，切换到非5G SA网络注册语音承载。
如前所述，在相关技术中，若终端与网络侧的IMS承载建立失败，则终端可以接收到网络侧返回的IMS承载建立失败的原因值。根据3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)协议中所定义的规则，终端在接收到网络侧发送的IMS承载建立失败的原因值后，需要根据原因值确定是否需要重新发送IMS承载建立请求，以及重新发送IMS承载建立请求的时间间隔。
举例而言，3GPP协议中定义了当IMS承载建立失败的原因为网络拒绝NETWORK_REJECT时，网络侧向终端发送的IMS建立失败的原因值为27，且3GPP协议中还定义了原因值27所对应的时间间隔为16秒。因此基于协议要求，终端在接收到网络侧返回的IMS承载建立失败的原因值27的情况下，需要在等待16秒后才能够重新向网络侧发送IMS承载建立请求。若IMS承载再次建立失败，则依旧需再次等待16秒才能够重新发送IMS承载建立请求。
而在连续多次IMS承载建立失败，尤其是连续多次IMS承载建立失败的原因值为27的情况下，终端由于长时间未能成功建立IMS承载，而长时间无法注册语音承载，使得终端长时间无法执行语音或视频通话业务，严重影响了用户的使用体验。
在一个实施例中，终端在接收到的网络侧发送的IMS承载建立失败的原因值的情况下，可以根据接收到的IMS承载建立失败的原因值确定IMS承载建立失败的原因。若终端确定IMS承载建立失败的原因包括网络拒绝，且IMS承载连续建立失败的次数 大于或等于预设次数，且终端当前驻留的网络为5G SA网络，则终端可以确定其当前驻留的5G SA网络很有可能存在网络异常或者不支持VoNR，在短时间内终端无法在该5G SA网络成功注册语音承载。因此，终端通过自动切换到非5G SA网络上注册VoLTE，以使得终端能够正常执行语音或视频通话业务。
举例而言，终端在驻留到5G SA网络后向网络侧发送IMS承载建立请求，若终端接收到网络侧返回的IMS承载建立失败的原因值为27，则终端可以确定IMS承载建立失败的原因包括网络拒绝。根据3GPP协议的要求，终端在等待16秒后可以重新向网络侧发送IMS承载建立请求。在预设次数为2次的情况下，若终端在重新发送IMS承载建立请求后再次接收到网络侧返回的IMS承载建立失败的原因值为27，则可以确定IMS承载建立失败的次数等于预设次数，终端可以通过自动关闭5G SA功能以重新针对4G网络和5G SA网络进行搜网和注册，并在根据搜网结果驻留到新的非5G SA网络后，可以在其驻留的非5G SA网络注册VoLTE。
在一个实施例中，所述次数包括预设时长内IMS承载建立连续失败的次数；其中，所述预设时长和/或所述预设次数与所述IMS承载建立失败的原因相关联。除了如前所述的网络拒绝的原因外，当IMS承载建立失败的原因为与终端当前驻留的5G SA网络存在网络异常有关的其他原因时，终端也可以在IMS承载建立失败的次数大于或等于预设次数的情况下切换到非5G SA网络注册语音承载。
终端可以预先为不同的IMS承载建立失败的原因关联不同的预设时长和/或预设次数。例如，相比于重新发送IMS承载建立请求的时间间隔为16秒的原因值27，3GPP协议中所定义的其他原因值所对应的重新发送IMS承载建立请求的时间间隔较短。在预设时长相同等待情况下，可以设置重新发送IMS承载建立请求的时间间隔越短的原因值所对应的预设次数越大。
举例而言，原因值27所对应的预设次数可以为2次，当终端在5G SA网络下，连续接收到2次网络侧返回的IMS承载失败的原因值为27时，终端即可切换到非5G SA网络注册语音承载。而对于某一重新发送IMS承载建立请求的时间间隔为2秒的原因值所对应的预设次数可以为8次，当终端在5G SA网络下连续接收到8次该原因值时，终端才需要切换到非5G SA网络注册语音承载。
图3是根据本公开的实施例示出的另一种语音承载注册方法的示意图。如图3所示，所述在所述终端满足预设条件的情况下，切换到非5G SA网络注册语音承载，包括：
在步骤S301中，在所述终端当前驻留网络为5G SA网络，且所述终端进行IMS VoWIFI注册成功，且所述终端处于通话场景的情况下，切换到非5G SA网络注册语音承载。
如前所述，VoNR技术并未被大规模商用，终端所驻留的5G SA网络很可能并不支持VoNR。通话因此终端在通过VoWIfI进行通话的过程中，若终端从WIFI网络切换到5G SA网络驻留，则很可能会因为终端所切换的5G SA网络并不支持VoNR而无法成功注册VoNR，进而导致掉话。
根据本实施例，在终端进行IMS VoWIFI注册成功，且所述终端处于通话场景的情况下，若确定所述终端当前驻留网络为5G SA网络，则可以确定当前终端是在IMS VoWIFI通话的过程中出现了WIFI信号弱或者WIFI信号丢失的情况，需要从WIFI网络切换到蜂窝网络驻留。而由于终端当前驻留的蜂窝网络为具有较大概率不支持语音承载的5G SA网络，因此，终端可以通过关闭5G SA功能以对5G SA网络进行降级处理，以自动切换到非5G SA网络注册VoLTE，从而可以使终端在用户无感知的情况下从VoWIFI通话业务切换为VoLTE通话业务，避免终端无法在切换后的蜂窝网络注册语音承载导致通话中断。
图4是根据本公开的实施例示出的另一种语音承载注册方法的示意图。如图4所示，所述判断所述终端是否满足预设条件，包括：
在步骤S401中，在所述终端的预设状态变化时，判断所述终端是否满足预设条件。
在一个实施例中，终端在判断是否满足网络切换的预设条件前，可以先根据终端的预设状态变化确定是否满足判断是否需要进行网络切换的触发条件。即终端可以仅在预设状态发生变化(判断逻辑的触发条件被满足)的情况下，再判断终端是否满足预设条件，而无需对终端是否满足预设条件进行实时检测，节约了终端的处理资源。
在一个实施例中，所述预设状态包括以下至少之一：通话状态；IMS VOWIFI注册状态；网络状态。
其中，通话状态可以包括IDLE空闲态(无任何通话活动)、DISCONNECTED连接断开(通话挂断完成)、DISCONNECTIN连接断开过程中(通话挂断过程中)、GACTIVE激活态(正在通话)、DIALING拨号态(呼出电话)等9种详细的通话状态。或者，终端也可以将对上述9种详细的通话状态进行概括，仅区分为无通话活动 和通话活动进行中这两种通话状态，本公开对此不作限制。
其中，IMS VOWIFI注册状态可以实际指的是IMS承载基础上的语音承载的注册状态，在本实施例中可以包括VoWIFI注册状态和VoWIfi未注册状态。
其中，网络状态可以包括终端所注册网络的网络制式和组网模式，例如可以包括5G SA网络、5G NSA网络和4G网络，本公开对此不作限制。
图5是根据本公开的实施例示出的另一种语音承载注册方法的示意图。如图5所示，所述在所述终端的预设状态变化时，判断所述终端是否满足预设条件，包括：
在步骤S501中，监听所述终端的通话状态；
在步骤S502中，在所述终端的通话状态变为激活态的情况下，判断所述终端是否满足预设条件。
在一个实施例中，终端可以仅针对通话状态进行实时监听，且仅关注通话状态中的空闲态和激活态这两种。每当监听到终端的通话状态从空闲态变为了激活态时，终端即可确定满足判断是否进行网络切换的触发条件。从而进一步具体判断终端是否同时满足终端处于当前驻留网络为5G SA网络、终端进行IMS VoWIFI注册成功，终端处于通话场景这三个预设条件，并在确定终端同事满足这三个预设条件的情况下，切换到非5G SA网络注册语音承载。
在一个实施例中，终端可以仅针对通话状态进行实时监听，且终端可以将9种详细的通话状态中的IDLE(空闲)、DISCONNECTED(连接断开)和DISCONNECTING(连接断开中)这三种状态视为无通话活动的状态，将其他六种状态视为通话活动进行中的状态。每当根据监听到终端的通话状态确定终端从无通话活动的状态变为了通话活动进行中的状态时，终端即可确定满足判断是否进行网络切换的触发条件。从而进一步具体判断终端是否同时满足终端处于当前驻留网络为5G SA网络、终端进行IMS VoWIFI注册成功，终端处于通话场景这三个预设条件，并在确定终端同事满足这三个预设条件的情况下，切换到非5G SA网络注册语音承载。
图6是根据本公开的实施例示出的另一种语音承载注册方法的示意图。
如图6所示，所述在所述终端的预设状态变化时，判断所述终端是否满足预设条件，包括：
在步骤S601中，监听所述终端的通话状态、IMS VOWIFI注册状态和网络状 态；
在步骤S602中，在所述终端的IMS状态变为IMS VoWIFI注册成功，和/或根据所述终端的网络状态变为5G SA网络，和/或所述终端的通话状态变为激活态的情况下，判断所述终端是否满足预设条件。
在一个实施例中，终端可以进一步针对通话状态、IMS VOWIFI注册状态以及网络状态这三种状态的变化进行实时监听。通过监听终端的通话状态，终端可以及时判断终端的通话状态是否从空闲态变为了激活态(或者从无通话活动的状态变为了通话活动进行中的状态)；通过监听终端的IMS VOWIFI注册状态，终端可以及时确定VoWIFI是否从未注册状态变化为了注册状态；通过监听终端的网络状态，终端可以及时确定终端当前所驻留网络的网络制式以及组网模式，以判断终端的网络状态是否从其他网络变为了5G SA网络。
在监听到终端的IMS VOWIFI从未注册成功状态变为了注册成功状态，或者终端的网络状态从其他网络变为了5G SA网络，或者终端的通话状态从空闲态变为了激活态(或者从无通话活动的状态变为了通话活动进行中的状态)这三种变化中的任一变化时，终端即可确定满足判断是否进行网络切换的触发条件。从而可以进一步具体判断终端是否同时满足终端处于当前驻留网络为5G SA网络、终端进行IMS VoWIFI注册成功，终端处于通话场景这三个预设条件，并在确定终端同事满足这三个预设条件的情况下，切换到非5G SA网络注册语音承载。
图7是根据本公开的实施例示出的另一种语音承载注册方法的示意图。如图7所示，所述方法还包括：
在根据监听到的通话状态确定所述终端的通话状态未处于激活态的情况下，切换到所述5G SA网络。
在一个实施例中，当根据监听到的通话状态确定终端的通话状态从激活态变为了空闲态(或者从通话活动进行中的状态变为了无通话活动的状态)时，终端可以确定此次通话结束，终端无需再使用语音承载。因此，终端可以通过自动打开5G SA功能以使得终端可以再次切换至5G SA网络，提高终端进行其他数据业务时的网络质量。
在一个实施例中，终端在每次进行开机或者关闭飞行模式等进行应用初始化的时刻，可以自动开启5G SA功能以启用终端5G SA网络的接入能力，以避免终端由于异常重启等情况而在切换至非5G SA网络后未能恢复终端的5G SA功能。
在一个实施例中，所述方法还包括：
记录所述终端切换到非5G SA网络注册语音承载的第一时刻，其中，从所述第一时刻开始的预设时长范围内，所述终端保持所在网络模式不变；和/或
记录所述终端切换到5G SA网络的第二时刻，其中，从所述第一时刻开始的预设时长范围内，所述终端保持所在网络模式不变。
在一个实施例中，为了避免终端连续多次执行切换至非5G SA网络注册语音承载的动作，终端可以对其所执行的切换到非5G SA网络注册语音承载的动作进行记录，以便终端在再次确定满足预设条件时，可以根据记录的信息确定终端在预设时长内已执行过切换至非5G SA网络注册语音承载的动作，避免此次重复执行。
例如，终端可以记录切换到非5G SA网络注册语音承载的第一时刻，并在注册语音承载后启动定时时长为预设时长的定时器，在定时器运行过程中，若再次判断终端满足预设条件，则可以直接忽视，保持驻留在当前所驻留的非5G SA网络上，无需重复执行切换到非5G SA网络注册语音承载的动作。
在一个实施例中，为了避免终端连续多次执行切换至5G SA网络的动作，终端可以对其所执行的切换到5G SA网络的动作进行记录，以便终端在再次确定通话状态未处于激活态时，可以根据记录的信息确定终端在预设时长内已执行过切换至5G SA网络的动作，避免此次重复执行。
例如，终端可以记录切换到5G SA网络的第二时刻，并在切换到5G SA网络后启动定时时长为预设时长的定时器，在定时器运行过程中，若再次判断确定终端的通话状态未处于激活态，则可以直接忽视，保持驻留在当前所驻留的5G SA网络上，无需重复执行切换到5G SA网络的动作。
与前述的语音承载注册方法的实施例相对应，本公开还提供了语音承载注册装置的实施例。
