技术领域
本申请属于通信技术领域，具体涉及一种网络切换方法、装置和电子设备。
背景技术
随着移动通信技术的不断发展，移动通信网络的类型越来越多，例如，第五代(5th-Generation，5G)网络、第四代(4th–Generation，4G)网络、第三代(3rd-Generation，3G)网络等。通常，代数越高的移动通信网络往往可以提供更优质的网络服务，然而在一些情况下，需要由代数较高的移动通信网络回落至代数较低的移动通信网络以执行业务。例如，由于5GC(5G核心网)并不成熟，因此初期的5G独立组网(5G Standalone，5G SA)网络语音业务采用演进的分组网络回落(Evolved Packet System fallback，EPS fallback)方式回落到长期演进(Long Term Evolution，LTE)网络的模式来解决，也即语音通话过程中网络回落到4G网络。
在实现本申请过程中，发明人发现现有技术中，在终端设备回落至代数较低的移动通信网络执行业务之后，需要网络下发重定向的消息来指示终端回到代数较高的移动通信网络，而在网络重定向异常的情况下终端设备一直停留在代数较低的移动通信网络，这样容易导致网络通信服务质量较差。

具体实施方式
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，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的 网络切换方法进行详细地说明。
参见图1，图1是本申请实施例提供的网络切换方法的流程图之一，如图1所示，该网络切换方法包括以下步骤：
步骤101、终端设备从第一移动通信网络切换到第二移动通信网络，并基于所述第二移动通信网络执行目标业务，其中，所述第一移动通信网络为第N代移动通信网络，所述第二移动通信网络为第M代移动通信网络，M小于N，M和N均为正整数。
本申请实施例中，在上述第一移动通信网络为5G SA网络的情况下，上述第二移动通信网络可以是LTE网络(即4G网络)、3G网络和第二代(2th–Generation，2G)网络等中的任一项；在上述第一移动通信网络为LTE网络的情况下，上述第二移动通信网络可以是3G网络和2G网络等中的任一项；在上述第一移动通信网络为3G网络的情况下，上述第二移动通信网络可以是2G网络。上述目标业务可以是语音业务，也可以是数据业务。
需要说明的是，上述从第一移动通信网络切换到第二移动通信网络，可以包括由第一移动通信网络直接切换到第二移动通信网络，例如，由5G SA网络直接切换至LTE网络，或者由5G SA网络直接切换至电路交换(Circuit Switched，CS)域网络；也可以包括由第一移动通信网络间接地切换到第二移动通信网络，例如，由第一移动通信网络切换至第三移动通信网络，再由第三移动通信网络切换至第二移动通信网络，具体举例来说，由5G SA网络切换至LTE网络，再由LTE网络切换至CS域网络。
步骤102、终端设备在基于所述第二移动通信网络完成所述目标业务的情况下，执行对所述第一移动通信网络的小区测量，得到测量结果。
本申请实施例中，终端设备在基于第二移动通信网络完成所述目标业务的情况下，可以直接执行第一移动通信网络的小区测量；也可以仅在未接收到网络侧下发的用于指示重定向到第一移动通信网络的释放(Release)消息的情况下执行第一移动通信网络的小区测量，而在接收到网络侧下发的用于指示重定向到第一移动通信网络的释放消息的情况下可以发起重定向过程，以切换回第一移动通信网络。
步骤103、终端设备根据所述测量结果，从所述第二移动通信网络切换 回所述第一移动通信网络。
本申请实施例中，终端设备可以基于测量结果选择最优的第一移动通信网络的小区发起接入，以切换回第一移动通信网络，这样可以提高通信服务质量。
为了便于理解，以下结合举例进行说明：
以上述第一移动通信网络是5G SA网络，上述第二移动通信网络是LTE网络，目标业务为语音业务为例，终端设备在5G SA网络上发起语音呼叫，并可以通过EPS fallback回落到LTE网络以基于LTE网络进行语音通话，在语音通话结束的情况下，触发5G SA网络的小区测量，并可以基于测量结果选取最优的5G SA网络的小区发起接入，以快速地切换回5G SA网络。
以上述第一移动通信网络是5G SA网络，上述第二移动通信网络是电路交换(Circuit Switched，CS)域网络，目标业务为语音业务为例，终端设备在5G SA网络上发起语音呼叫，并可以通过EPS fallback方式回落到LTE网络，若在LTE网络上建立语音承载失败，则继续回落至CS域网络以基于CS域网络进行语音通话，在语音通话结束的情况下，触发5G SA网络的小区测量，并可以基于测量结果选取最优的5G SA网络的小区发起接入，以快速地切换回5G SA网络。
本申请实施例的网络切换方法，终端设备通过在基于所述第二移动通信网络完成目标业务的情况下，执行对所述第一移动通信网络的小区测量，并根据测量结果从所述第二移动通信网络切换回所述第一移动通信网络，能够实现快速地由第M代移动通信网络切换回第N代移动通信网络，避免长时间停留在第M代移动通信网络，进而可以提高网络通信服务质量。
参见图2，图2是本申请实施例提供的网络切换方法的流程图之二。本申请实施例与上一实施例的区别主要在于进一步限定了仅在未接收到用于指示重定向至所述第一移动通信网络的释放消息的情况下执行对所述第一移动通信网络的小区测量。本申请实施例中，所述在基于所述第二移动通信网络完成所述目标业务的情况下，执行对所述第一移动通信网络的小区测量，得到测量结果，包括：在基于所述第二移动通信网络完成所述目标业务的情况下，若未接收到用于指示重定向至所述第一移动通信网络的释放消息，则执 行对所述第一移动通信网络的小区测量，得到测量结果；所述方法还包括：在基于所述第二移动通信网络完成所述目标业务的情况下，若接收到用于指示重定向至所述第一移动通信网络的释放消息，则执行重定向过程。
如图2所示，本申请实施例提供的网络切换方法包括以下步骤：
步骤201、终端设备从第一移动通信网络切换到第二移动通信网络，并基于所述第二移动通信网络执行目标业务，其中，所述第一移动通信网络为第N代移动通信网络，所述第二移动通信网络为第M代移动通信网络，M小于N，M和N均为正整数。
该步骤同上述步骤101，为避免重复，在此不做赘述。
步骤202、终端设备在基于所述第二移动通信网络完成所述目标业务的情况下，若未接收到用于指示重定向至所述第一移动通信网络的释放消息，则执行对所述第一移动通信网络的小区测量，得到测量结果。
本申请实施例中，在完成目标业务之后若没有接收到用于指示重定向至所述第一移动通信网络的释放消息，则执行第一移动通信网络的小区测量，以基于测量结果从所述第二移动通信网络切换回所述第一移动通信网络，否则执行步骤204，也即基于用于指示重定向至所述第一移动通信网络的释放消息执行重定向过程，以切换回第一移动通信网络。
步骤203、终端设备根据所述测量结果，从所述第二移动通信网络切换回所述第一移动通信网络。
该步骤同上述步骤103，为避免重复，在此不做赘述。
步骤204、终端设备在基于所述第二移动通信网络完成所述目标业务的情况下，若接收到用于指示重定向至所述第一移动通信网络的释放消息，则执行重定向过程。
本申请实施例中，若在完成所述目标业务的情况下接收到用于指示重定向至所述第一移动通信网络的释放消息，则终端设备可以基于用于指示重定向至所述第一移动通信网络的释放消息发起重定向过程，以重定向至第一移动通信网络，可以提高切换回第一移动通信网络的速度，进一步提高通信服务质量。
为了便于理解，以下结合举例进行说明：
终端设备在5G SA网络上发起语音呼叫，并通过EPS fallback方式回落到LTE网络，若在LTE网络建立语音承载成功，则通过LTE网络进行语音通话，在该情况下，在语音通话结束后，若未接收到用于指示重定向至5G SA网络的释放消息，则触发5G SA网络的小区测量，以基于测量结果切换回5G SA网络，若接收到用于指示重定向至5G SA网络的释放消息，则发起重定向过程，以重定向至5G SA网络。若在LTE网络建立语音承载失败，则可以继续回落至CS域网络以基于CS域网络进行语音通话，在该情况下，语音通话结束后，可以忽略接收到的重定向至LTE网络的释放消息，并触发5G SA网络的小区测量，以基于测量结果切换回5G SA网络。
本申请实施例的网络切换方法，终端设备在未接收到用于指示重定向至所述第一移动通信网络的释放消息的情况下执行对所述第一移动通信网络的小区测量，以基于测量结果切换回第一移动通信网络，避免长时间停留在第二移动通信网络，而在接收到用于指示重定向至所述第一移动通信网络的释放消息的情况下发起重定向过程，以重定向至第一移动通信网络，可以提高切换回第一移动通信网络的速度和接入的第一移动通信网络的小区的质量，进而提高通信服务质量。
可选地，所述在基于所述第二移动通信网络完成所述目标业务的情况下，若未接收到用于指示重定向至所述第一移动通信网络的释放消息，则执行对所述第一移动通信网络的小区测量，得到测量结果，包括：
在基于所述第二移动通信网络完成所述目标业务的情况下，启动定时器；
若在所述定时器超时之前未接收到用于指示重定向至所述第一移动通信网络的释放消息，则执行对所述第一移动通信网络的小区测量，得到测量结果。
本申请实施例中，上述定时器的时长可以根据实际情况进行合理设置，例如，上述定时器的时长可以是3秒、4秒等。具体地，可以预先根据统计的网络下发用于指示重定向至所述第一移动通信网络的释放消息的时间设置定时器的时长，例如，网络侧通常是在语音通话结束的2秒内下发用于指示重定向至5G SA网络的释放消息，则可以设置上述定时器的时长为2秒，或稍大于2秒的时长，例如3秒。
实际应用中，终端设备可以在完成目标业务的情况下启动定时器，若在定时器超时之前接收到用于指示重定向至所述第一移动通信网络的释放消息，则可以关闭定时器，并发起重定向至第一移动通信网络的过程；若定时器超时，则说明在定时器超时之前未接收到用于指示重定向至所述第一移动通信网络的释放消息，该情况下执行对所述第一移动通信网络的小区测量，以基于测量结果切换回第一移动通信网络。
为了便于理解，以下结合举例进行说明：
终端设备在5G SA网络上发起语音呼叫，并通过EPS fallback方式回落到LTE网络，若在LTE网络建立语音承载成功，则通过LTE网络进行语音通话，若在LTE网络建立语音承载失败，则可以继续回落至CS域网络以基于CS域网络进行语音通话。在语音通话结束后，启动定时器，若定时器超时，则执行5G SA网络的小区测量，若定时器超时前收到用于指示重定向至5G SA网络的释放消息，则可以关闭定时器，并发起重定向至5G SA网络的过程。
本申请实施例通过启动定时器来判断用于指示重定向至所述第一移动通信网络的释放消息的接收与否，判断结果较为合理、准确，进而可以更为合理、准确地实现由第二移动通信网络向第一移动通信网络的切换。
可选地，所述从第一移动通信网络切换到第二移动通信网络，并基于所述第二移动通信网络执行目标业务之前，所述方法还包括：
记录当前驻留的所述第一移动通信网络的频点；
所述在基于所述第二移动通信网络完成所述目标业务的情况下，执行对所述第一移动通信网络的小区测量，得到测量结果，包括：
在基于所述第二移动通信网络完成所述目标业务的情况下，基于测量邻区列表执行对所述第一移动通信网络的小区测量，得到测量结果，其中，所述测量邻区列表包括多个频点，所述多个频点包括记录的所述第一移动通信网络的频点，且记录的所述第一移动通信网络的频点的测量优先级最高。
本申请实施例中，上述测量邻区列表可以包括多个待测量的频点，其中，在所述测量邻区列表中记录的所述第一移动通信网络的频点的测量优先级最高。可选地，上述测量邻区列表可以包括全频段内的频点，也可以仅包括电 子设备的移动运营商所支持的频点。实际应用中，可以在基于所述第二移动通信网络完成所述目标业务的情况下，依次测量测量邻区列表中的频点的信号质量，得到测量结果。
本申请实施例中，终端设备在需要由第一移动通信网络切换至第二移动通信网络的情况下，可以在切换前记录当前驻留的第一移动通信网络的频点，这样在完成目标任务后需要进行第一移动通信网络的小区测量的情况下，可以优先测量记录的第一移动通信网络的频点。
例如，可以在终端设备在5G SA网络上发起语音呼叫业务的情况下，记录当前驻留的5G SA网络的小区的新空口绝对射频频率信道编号(New Radio Absolute Radio Frequency Channel Number，NRARFCN)，这样在由5G SA网络切换至LTE网络或CS域网络完成语音通话后，可以优先测量记录的5G SA网络的小区的NRARFCN，例如，将记录的5G SA网络的小区的NRARFCN添加至测量邻区列表的首位，以加快找到最优小区的速度。
需要说明的是，本申请实施例还可以在切换前记录当前驻留的第一移动通信网络的小区，例如，记录切换前记录当前驻留的第一移动通信网络的小区标识，这样在便于快速切换回该小区。
本申请实施例通过记录切换前记录驻留的第一移动通信网络的频点，并在执行第一移动通信网络的小区测量的过程中优先测量记录的第一移动通信网络的频点，这样可以提高找到最优小区进行接入的速度。
可选地，所述在基于所述第二移动通信网络完成所述目标业务的情况下，执行对所述第一移动通信网络的小区测量，得到测量结果，包括：
若在执行所述目标业务的过程中处于移动状态，则在基于所述第二移动通信网络完成所述目标业务的情况下，执行对所述第一移动通信网络的小区测量，得到测量结果；
所述方法还包括：
若在执行所述目标业务的过程中处于静止状态，则在基于所述第二移动通信网络完成所述目标业务的情况下，在切换前驻留的所述第一移动通信网络的小区上发起接入。
本申请实施例中，终端设备在执行目标业务的过程中若终端设备处于移 动状态，例如，移动距离大于预设距离，该种情况下切换前驻留的第一移动通信网络的小区的信号质量容易发生变化，此时执行第一移动通信网络的小区测量，并可以基于测量结果选取最优的第一移动通信网络小区发起接入，从而可以提高通信质量；而在执行目标业务的过程中若终端设备处于静止状态，例如，移动距离小于预设距离，该种情况下切换前驻留的第一移动通信网络的小区的信号质量往往不会发生变化或是发生较小的变化，此时可以直接在切换前驻留的第一移动通信网络的小区上发起接入，可以在保证通信服务质量的同时提高切换速度。
以下结合具体示例对本申请实施例进行说明：
参见图3，图3是本申请实施例提供的网络切换方法的流程图之三。如图3所示，本申请实施例提供的网络切换方法包括以下步骤：
步骤301、终端设备驻留在5G SA网络下。
步骤302、终端设备在5G SA网络下发起语音通话。
步骤303、记录当前驻留的5G SA网络的小区和频点到快速(Quickly return back，QRB)列表。
例如，记录当前驻留的5G SA网络的小区标识和NRARFCN至QRB列表，如表1所示。

步骤304、通过EPS fallback回落至LTE网络。
步骤305、在LTE网络建立语音承载是否成功。
该步骤中，若在LTE网络建立语音承载成功，则执行步骤306，否则执行步骤307。
步骤306、基于LTE网络的语音通话结束。
步骤307、继续回落至CS域网络发起语音业务。
步骤308、在CS域网络的语音通话结束。
步骤309、启动定时器。
步骤310、定时器是否超时。
该步骤中，若定时器超时，则执行步骤311，否则执行步骤314。
步骤311、发起新空口(New Radio，NR)邻区测量。
该步骤中，测量目标是5G SA网络的邻区频点，以通过最优小区选择回到5G SA网络。
步骤312、将QRB列表中的频点加入到测量邻区列表的首位。
例如，如表2所示，将QRB列表中记录的5G SA网络的小区的NRARFCN加入到测量邻区列表的首位，以优先测量录的5G SA网络的小区的NRARFCN。
表2
索引 NRARFCN

3 523012
…… ......
步骤313、根据测量结果进行小区选择，以切换回5G SA网络。
步骤314、收到网络下发的重定向至5G SA网络的释放消息。
步骤315、发起重定向过程。
