具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
在本发明实施例中，终端包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、车载移动终端、可穿戴设备、以及计步器等。
参见图1，图1是本发明实施例提供的一种业务注册方法的流程图之一，所述方法应用于终端，所述终端包括第一用户身份识别卡模块和第二用户身份识别卡模块，所述第一用户身份识别卡模块与第一用户身份识别卡关联，所述第二用户身份识别卡模块与第二用户身份识别卡关联，如图1所示，包括以下步骤：
步骤101、基于所述第一用户身份识别卡接入第一移动网络。
其中，可以在终端未连接Wi-Fi，例如无Wi-Fi可用的情况下，基于所述第一用户身份识别卡接入第一移动网络。以终端为手机为例，第一用户身份识别卡和第二用户身份识别卡可以分别为手机的SIM卡1和SIM卡2。可以打开手机的数据网络开关，将手机接入移动网络。所述第一移动网络可以为LTE网络，或者，还可以为其他网络。终端可以通过第一用户身份识别卡模 块与第一用户身份识别卡进行通信，并可以通过第二用户身份识别卡模块与第二用户身份识别卡进行通信。
步骤102、基于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息。
其中，可以是在未检测到无线局域网络信号的情况下，基于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息；或者可以是，在未检测到无线局域网络信号，且所述第二用户身份识别卡的移动网络信号参数低于第一预设值的情况下，基于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息；或者还可以是，在未检测到无线局域网络信号，所述第二用户身份识别卡的移动网络信号参数低于第一预设值，及所述第一用户身份识别卡的移动网络信号参数高于第七预设值的情况下，基于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息。本发明实施例对此不进行限定。
另外，所述基于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息，可以是，基于所述第一移动网络在终端和网络侧设备之间传输所述第二用户身份识别卡的VoWiFi注册消息。
在实际应用中，通过VoWiFi技术，运营商可以利用Wi-Fi热点，为用户提供语音服务。通过VoWiFi技术，用户可以采用Wi-Fi接入，在使用移动互联网的同时，拨打或接听语音或视频电话。现有技术中，使用VoWiFi需要连接可用的Wi-Fi，但用户在户外或其它无Wi-Fi的地方，无法使用VoWiFi。本发明实施例中，基于所述第一用户身份识别卡接入第一移动网络，基于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息。能够在无Wi-Fi的情况下，支持终端的第二用户身份识别卡利用第一用户身份识别卡的移动网络数据流量进行VoWiFi业务。
需要说明的是，VoWiFi目前可以通过三种组网方式实现，分别为通过S2b接口协议非可信接入3GPP网络，通过S2a接口协议可信接入3GPP网络，以及通过S2c接口协议网络直接接入IMS。针对这三种组网方式，从技术方面分析，尤其是从对网络的影响和终端成熟度来分析，对于已经部署大量WLAN接入点的运营商来说，采用通过S2a接口协议可信接入3GPP网络，需要升 级改造或者直接替换全网WLAN接入点设备，施工周期长、成本高、及难度大；而采用通过S2b接口协议非可信接入3GPP网络，可以结合公共Wi-Fi网络的开放性和运营商核心网的高可靠性、QoS保证等特性，可以以较低成本实现语音在WLAN和LTE网络间的无缝切换。因此，通过S2b接口协议非可信接入3GPP网络的方案将逐步取代通过S2a接口协议可信接入3GPP网络的方案，成为目前较可行的VoWiFi组网方案。通过S2b接口协议非可信接入3GPP网络的组网方案中，终端可以通过非信任域Wi-Fi网络接入到运营商的3GPP网络，认证鉴权后可以将呼叫请求路由到IMS进行处理，实现语音、短信、及补充业务等IMS业务。并且在S2b接口协议非可信接入3GPP网络的组网方案中，为实现VoWiFi业务，仅需新增演进型分组数据网关(Evolevd Packet Data Gateway，EPDG)网元和3GPP验证、授权和记账(Authentication Authorization and Accounting，AAA)网元即可。在本发明实施例中，可以采用通过S2b接口协议非可信接入3GPP网络的组网方案实现VoWiFi业务。
另外，网络侧设备可以包括核心网侧设备。如图2所示，网络侧设备可以包括如下网元：移动管理实体(Mobility Management Entity，MME)、分组数据网关(Packet Data Network GW，PGW)、EPDG及归属签约用户服务器(Home Subscriber Server，HSS)。终端可以接入LTE网络，终端的SIM卡1和SIM卡2可以通过LTE网络与网络侧设备进行通信。如图2所示，SIM卡1可以通过LTE1网络、MME1、PGW1、HSS、及IMS服务器之间的通信实现通过LTE1网络注册上VoLTE；SIM卡2可以通过LTE2网络、MME2、PGW2、HSS、及IMS服务器之间的通信实现通过LTE2网络注册上VoLTE；SIM卡2可以通过LTE1网络、MME1、PGW1、HSS、EPDG、PGW2及IMS服务器之间的通信实现通过SIM卡1连接的LTE1网络从VoLTE切换到VoWiFi。
在实际应用中，作为一种实施方式，终端上可以设置有SIM卡1和SIM卡2，且SIM卡1和SIM卡2可以均注册上VoLTE，SIM卡1可以连接第一移动网络。当SIM卡1网络信号质量和强度较强且处于空闲态，SIM卡2网络信号较弱或无网络信号时，SIM卡2可以透过SIM卡1连接的网络注册上 VoWiFi，SIM卡2可以通过VoWiFi进行拨号或接听。SIM卡1和SIM卡2可以接入LTE网络，MME可以分别将SIM卡1和SIM卡2的接入点名(Access Point Name，APN)和PGW信息注册到HSS。若终端检测到SIM卡2的移动网络信号参数低于第一预设值，且SIM卡1的移动网络信号参数高于第七预设值，可以触发SIM卡2切换到VoWiFi。SIM卡2可以使用SIM卡1连接的第一移动网络附着到EPDG。EPDG可以从HSS中获取APN和PGW信息。EPDG可以选择接入切换前相同的PGW，可以在PGW侧删除SIM卡2原有的资源。SIM卡2通过EPDG和PGW注册上VoWiFi后，可以利用VoWiFi进行通话。当终端检测到SIM卡2的移动网络信号参数高于第二预设值，和/或，SIM卡1的移动网络信号参数低于第三预设值时，可以触发SIM卡2从VoWiFi切换到VoLTE。
在实际应用中，作为另一种实施方式，终端上可以设置有SIM卡1和SIM卡2，当终端为双卡单通终端时，当SIM卡1正在进行VoLTE电话且SIM卡1网络信号质量和强度较强时，SIM卡2可以透过SIM卡1连接的网络注册上VoWiFi，SIM卡2可以通过VoWiFi进行拨号或接听。SIM卡1和SIM卡2可以接入LTE网络，MME可以分别将SIM卡1和SIM卡2的APN和PGW信息注册到HSS。当SIM卡1正在进行VoLTE电话且SIM卡1网络信号质量和强度较强时，可以触发SIM卡2切换到VoWiFi。SIM卡2可以使用SIM卡1连接的第一移动网络附着到EPDG。EPDG从HSS中获取APN和PGW信息。EPDG可以从HSS中获取APN和PGW信息。EPDG可以选择接入切换前相同的PGW，可以在PGW侧删除SIM卡2原有的资源。SIM卡2通过EPDG和PGW注册上VoWiFi后，当SIM卡2来电后，可以利用VoWiFi进行通话。SIM卡1的VoLTE电话结束后，若终端检测到SIM卡2的移动网络信号参数高于第二预设值，和/或，SIM卡1的移动网络信号参数低于第三预设值时，则可以触发SIM卡2从VoWiFi切换到VoLTE。
需要说明的是，若SIM卡2未检测到网络信号或者未接入LTE网络，则在进行VoWiFi注册的过程中，可以直接在注册消息中携带Attach标识进行VoWiFi注册。
本发明实施例中，基于所述第一用户身份识别卡接入第一移动网络；基 于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息。这样，能够通过第一用户身份识别卡接入的移动网络进行第二用户身份识别卡的VoWiFi注册以及VoWiFi通话业务，能够在终端未处于Wi-Fi网络环境下时，进行VoWiFi业务。
可选的，所述基于所述第一移动网络传输所述第二用户身份识别卡的无线局域网络语音VoWiFi注册消息之前，所述方法还包括：
