Description

语音业务切换方法、装置和用户设备

技术领域
本申请属于通信技术领域，具体涉及一种语音业务切换方法、装置和用户设备。
背景技术
目前，用户设备(user equipment，UE)的客户识别模块(subscriber identification module，SIM)卡1可以通过移动网络(例如SIM卡1的移动网络、SIM卡2的移动网络、无线保真(wireless-fidelity，WiFi)网络等)，连接至互联网协议多媒体子***(internet protocol multimedia subsystem，IMS)的核心网，以通过该移动网络进行语音业务。
但是，由于在SIM卡1通过移动网络进行语音业务时，可能会出现该移动网络的网络质量较差的情况，这样，可能会出现通话质量差、断线等情况，因此，可能会导致SIM卡1的语音业务的业务质量下降。
如此，导致UE的语音业务的业务质量较差。
发明内容
本申请实施例的目的是提供一种语音业务切换方法、装置和用户设备，能够解决UE的语音业务的业务质量较差的问题。
为了解决上述技术问题，本申请是这样实现的：

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，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。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。
图1示出了网络侧设备的架构示意图。如图1所示，网络侧设备可以包括以下网元中的一种或多种：
电子设备(例如可以是UE)、移动管理实体(mobility management entity，MME)网元、分组数据网关(packet data network GW，PGW)网元、演进型分组数据网关(evolevd packet datagateway，ePDG)、以及归属签约用户服务器(home subscriber server，HSS)。
其中，UE的SIM卡1和SIM卡2可以通过移动网络(例如长期演进(long term evolution，LTE)网络)与网络侧设备进行通信。具体地，UE可以通过SIM卡1的LTE网络1、MME1、PGW1、HSS及网际互联多媒体***(internet protocol multimedia subsystem，IMS)服务器之间的通信(图中是以实线进行示意的)，实现通过LTE网络1注册SIM卡1的LTE上的语音(voice over LTE，VoLTE)业务，以进行SIM卡1的VoLTE业务；UE也可以通过SIM卡2的LTE网络2、MME2、PGW2、HSS及IMS服务器之间的通信(图中是以虚线进行示意的)，实现通过LTE网络2注册SIM卡2的VoLTE业务，以进行SIM卡2的VoLTE业务。若在进行SIM卡2的VoLTE业务的过程中，出现LTE网络2的网络质量较差，则UE可以LTE网络1、MME1、PGW1、HSS、ePDG、PGW2及IMS服务器之间的通信(图中是以虚线进行示意的)，实现通过LET1网络注册SIM卡2的移动网络上的语音(voice over mobile，VoMobile)业务，以进行SIM卡2的VoMobile业务。
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语音业务切换方法、装置和用户设备进行详细地说明。
本申请实施例提供的语音业务切换方法可以应用于UE进行VoMobile业务的场景。
在一种场景下，在UE的SIM卡2进行VoMobile业务的情况下，可以向网络侧设备发送切换报告消息，该切换报告消息中包括表征进行VoMobile业务时UE对应的移动网络(例如SIM卡1的LTE网络1、SIM卡2的LTE网络2(或UE连接的WiFi网络))的网络质量的网络环境信息。从而网络侧设备可以接收切换报告消息，并确定该网络环境信息是否满足预设条件，并在确定该网络环境信息满足预设条件的情况 下，网络侧设备可以向UE发送切换命令消息，该切换命令消息用于指示将SIM卡2的VoMobile业务切换为VoLTE业务(或WiFi上的语音(voice over WiFi，VoWiFi)业务)，这样，UE可以根据该切换命令消息将SIM卡2的VoMobile业务切换为SIM卡2的VoLTE业务(或VoWiFi业务)。
在另一种场景下，在UE的SIM卡2进行VoLTE业务(或VoWiFi业务)的情况下，可以向网络侧设备发送切换报告消息，该切换报告消息中包括表征进行VoLTE业务(或VoWiFi业务)时UE对应的移动网络(例如SIM卡1的LTE网络1、SIM卡2的LTE网络2)的网络质量的网络环境信息。从而网络侧设备可以接收切换报告消息，并确定该网络环境信息是否满足预设条件，并在确定该网络环境信息满足预设条件的情况下，网络侧设备可以向UE发送切换命令消息，该切换命令消息用于指示将SIM卡2的VoLTE业务(或VoWiFi业务)切换为VoMobile业务，这样，UE可以根据该切换命令消息将SIM卡2的VoLTE业务(或VoWiFi业务)切换为SIM卡2的VoMobile业务。
可以理解，UE可以接收到网络侧设备发送的切换命令，并将SIM卡2的当前的语音业务切换为SIM卡2的其他语音业务，以通过其他移动网络进行SIM卡2的语音业务，因此，可以避免出现通话质量差、断线等情况，从而，可以避免SIM卡2的语音业务的业务质量下降，如此，可以提升UE的语音业务的业务质量。

进一步可选地，本申请实施例中，第一切换命令消息中可以包括网络侧设备的 ePDG网元的地址信息，从而语音业务切换装置可以先根据该第一切换命令消息，获取该ePDG网元的地址信息，并根据该ePDG网元的地址信息，通过WiFi网络，注册第二语音业务(即VoWiFi业务)，以执行VoWiFi业务的注册过程，然后再向网络侧设备发送VoWiFi业务注册成功消息，以使得网络侧设备的PGW2网元可以发起第二SIM卡的第一语音业务(即VoMobile业务)的相关承载资源释放，并执行第二SIM卡的VoMobile业务的去注册过程，以执行VoWiFi业务的切换过程。
如此可知，由于语音业务切换装置可以在第一SIM卡的移动网络的网络质量较差，且语音业务切换装置连接WiFi网络、和该WiFi网络的网络质量较好的情况下，接收到网络侧设备发送的第一切换命令，并执行VoWiFi业务的切换过程，以通过WiFi网络进行第二SIM卡的语音业务，因此，可以提升语音业务切换装置的语音业务的业务质量。

本申请实施例中，若第一网络质量参数大于第一阈值，则可以认为第一SIM卡的移动网络的网络质量较好；若第二网络质量参数小于或等于第二阈值、和/或第一网络环境信息包括第二信息，则可以认为第二SIM卡的移动网络的网络质量较差、和/或第二SIM卡的移动网络发生异常；若第一网络环境信息不包括WiFi网络的网络信号参数，则可以认为语音业务切换装置没有连接WiFi网络；若第一网络环境信息包括WiFi网络的网络信号参数、且该网络信号参数小于或等于第三阈值，则可以认为语音业务切换装置连接WiFi网络、且该WiFi网络的网络质量较差。因此，语音业务切换装置可以根据第一切换命令消息，执行第二SIM卡的VoMobile业务的切换过程，以通过第一SIM卡的LTE网络进行第二SIM卡的语音业务。
