 本发明的实施方式
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，所描述的实施例仅仅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。
本发明中的术语“第一”、“第二”和“第三”是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或模块的过程、方法、***、产品或设备没有限定于已列出的步骤或模块，而是可选地还包括没有列出的步骤或模块，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或模块。
本实施例提供一种呼叫的方法、存储介质以及终端。
本申请实施例提供一种呼叫的***，包括：本申请实施例提供的呼叫的装置，该呼叫的装置可以集成在终端中，该终端可以是手机、平板电脑、笔记本电脑等设备。此外呼叫的***还可以包括其他设备，比如服务器等设备。
例如，以该呼叫的***集成在终端中为例，参见图1，当该终端处于VoLTE或VoWiFi网络下，接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求，接收该验证服务器基于该验证请求返回的响应信息，然后，根据该响应信息确定通讯标识类型，再然后，根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。
本申请实施例提供的呼叫的方法，可实现在呼叫的装置中，该呼叫的装置具体可以集成在电子设备中，电子设备包括但不限于计算机、智能手表、手机、平板电脑等设备。
以下分别进行详细说明。需说明的是，以下实施例的顺序不作为对实施例优选顺序的限定。
在本实施例中，将从呼叫装置的角度进行描述，该呼叫装置具体可以集成在终端。其中，该终端可以包括手机、智能手表、平板电脑、笔记本电脑、个人计算机（PC，Personal Computer）等。
一种呼叫的方法，包括：当该终端处于VoLTE或VoWiFi网络下，接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求，接收该验证服务器基于该验证请求返回的响应信息，然后，根据该响应信息确定通讯标识类型，再然后，根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。
如图1所示，提供了一种呼叫的方法，该呼叫的方法可以由终端的处理器执行，具体流程可以如下：
当终端处于VoLTE或VoWiFi网络下，接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求。
其中，IMS(IP Multimedia Subsystem，IP多媒体子***）,是一种全新的多媒体业务形式，它能够满足的终端客户更新颖、更多样化多媒体业务的需求。IMS被认为是下一代网络的核心技术，也是解决移动与固网融合，引入语音、数据、视频三重融合等差异化业务的重要方式。
其中，VoLTE(Voice over Long-Term Evolution，长期演进语音承载），是一个面向手机和数据终端的高速无线通信标准。它基于IMS网络并承载于4G网络，使语音服务（控制和媒体层面）作为数据流在LTE（Long Term Evolution，长期演进)数据承载网络中传输，而不再需维护和依赖传统的电路交换语音网络，实现了数据与语音业务在同一网络下的统一。其中，VoWiFi（Voice over Wi-Fi，网路电话）与VoLTE都是基于IMS为基础的语音通话技术。VoWiFi与VoLTE主要的差别是前者是透过Wi-Fi作为接入点，后者则是接入基站，但两者最终都要接入IMS，受运营商控制与管理这项IP语音服务。
其中，通讯标识，即指电话号码。
其中，当前终端支持的通讯标识包括在当前运营商网络内预先客制化的电话号码以及SIM卡支持的电话号码。
其中，验证服务器是为IMS网络提供计算服务的设备。
其中，验证请求即为用户在呼叫电话时终端发送的会话建立信令。
例如，如该终端为手机，用户通过IMS网络拨打一些电话号码，若该电话号码不是该当前运营商网络内预先客制化的电话号码或是SIM卡支持的电话号码，则IMS会判断该短号码是否为紧急号码并将判断结果返回给当前终端，然后UE（ User Equipment，用户设备）会发起MO INVITE信令即会话建立信令给验证服务器。
接收该验证服务器基于该验证请求返回的响应信息。
例如，以步骤101中的例子为例，当验证服务器收到会话建立信令后会返回一个响应信息380 Alternative Service信令。
根据该响应信息确定通讯标识类型。
其中，通讯标识类型可以按大类分为紧急号码和普通号码。紧急号码是指用手机拨打112、110、119、120之类的报警或求救号码。普通号码是指除开紧急号码之外，普通用户之间相互沟通交流的所使用的号码。
在一些实施例中，步骤“根据该响应信息确定通讯标识类型”可以包括以下流程：
其中，响应信息携带类型标识符。
（11）根据该类型标识符确定所述通讯标识类型；
（12）识别所述类型标识符的前缀信息；
（13）根据所述前缀信息确定所述通信标识类型。
Contact中电话号码转换后的URI（Uniform Resource Identifier，统一资源标识符）类型，请参考如下表格：
Code 380AS Emergency URI Short Code Description Setup
999 urn:service:sos.ambulance Emergency medical services Emergency setup (Ambulance Guard: true)
998 urn:service:sos.fire Fire Rescue Emergency setup (Fire Brigade: true)
997 urn:service:sos.police Police Emergency setup (Police: true)
985 urn:service:sos.mountain See and Mountain rescue Emergency setup (Mountain rescue: true)
984 urn:service:sos.marine River rescue Emergency setup (Marine Guard: true)
996 urn:service:sos.country-specific.pl.996 Anti-terrorist center Setup (996)
995 urn:service:sos.country-specific.pl.995 Police - Child Alert system Setup (995)
994 urn:service:sos.country-specific.pl.994 Emergency water supply, Setup (994)
993 urn:service:sos.country-specific.pl.993 Emergency heating Setup (993)
992 urn:service:sos.country-specific.pl.992 Emergency gas works, Setup (992)
991 urn:service:sos.country-specific.pl.991 Emergency power Setup (991)
987 urn:service:sos.country-specific.pl.987 Crisis Management Center Setup (987)
986 urn:service:sos.country-specific.pl.986 Municipal Police Setup (986)
例如，以步骤102中的例子为例，响应信息380 Alternative Service信令并携带参数Contact URI，可以根据参数Contact URI的前缀信息去判断通讯标识的类型，例如，当参数Contact URI携带有urn:service:sos前缀时，IMS网络匹配到这些短号码是紧急号码。
根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。
其中，网络制式网络制式就是网络的类型，例如，我国手机的网络制式有CDMA手机占用的CDMA 1X，800MHZ频段；GSM手机占用的900/1800/1900MHZ 频段；近两年的GSM 1X双模（即WCDMA)占用的900/1800MHZ频段；3G占用的900/1800/1900/2100MHz频段；4G占用的1920--2170MHZ频段。联通4GTD LTE占用的2555-2575MHz，2300-2320MHz频段。
在一些实施例中，步骤“根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程”可以包括以下流程：
（21）根据所述通讯标识类型、及所述通讯标识，发起电路域回落，注册到2G/3G网络；
（22）基于所述2G/3G网络发起呼叫流程；
当该通讯标识类型为属于3GPP协议规定的紧急通讯标识时，基于2G/3G网络发送紧急拨号请求；
（23）当该通讯标识的类型不属于3GPP协议规定的紧急通讯标识，基于2G/3G网络发送普通拨号请求。
在一些实施例中，步骤“根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程”之后还可以包括以下流程：
（24）当通话结束后，确定当前网络制式；
（25）当当前网络制式为2G/3G网络时，切换当前网络制式重新注册到VoLTE或VoWiFi。
其中，3GPP（The 3rd Generation Partnership Project，第三代合作伙伴计划）是为了定义完整的端到端***规范，确保符合行业需求，不同厂商之间实现无缝互操作以及为移动提供其所必需的全球规模，并且也为了实现GSM由2G网络到3G网络的平滑过渡的需求。
其中，紧急拨号请求的信令是emergency_setup，普通拨号请求的信令是setup。例如，以步骤103中的例子为例，UE Modem（调制解调器）的IMS模块接收到响应信息后开始解析Contact URI中的内容，并将发起CSFB（Circuit Switched Fallback ，电路域回落），重新发起注册到2G/3G网络。若该电话号码为3GPP规定的紧急号码，则当前终端通过2G/3G网络发起紧急拨号。若该电话号码不是3GPP协议规定的紧急号码，则当前终端通过2G/3G网络发起普通拨号。
由于不是协议规定的紧急号码是无法接入到紧急呼叫中心的，并且拨打这类号码时，手机界面会提示紧急呼叫。当该不是协议规定的紧急号码拨出时，***会自动返回一个语音播报，大概持续两分钟左右。本方案将该转到普通拨号流程，由于该号码没有与之对应的终端，因此会在手机界面提示空号，从而避免用户因手机界面提示为紧急号码而多次拨打，耽误呼救时间。其中，被IMS网络判断为紧急号码的电话号码在呼出时，手机界面都会显示紧急呼叫。
本申请实施例在当终端处于VoLTE或VoWiFi网络下，接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求，接收所验证服务器基于该验证请求返回的响应信息，然后，根据该响应信息确定通讯标识类型，再然后，根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。该方案可以节省用户求救的时间，提高呼救效率。
根据上述描述的内容，下面将对本申请实施例提供的方法进行举例说明。
参考图2，一种呼叫的方法，具体流程可以包括：
当终端处于VoLTE或VoWiFi网络下，终端接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求。
其中，当前终端支持的通讯标识包括在当前运营商网络内预先客制化的电话号码以及SIM卡支持的电话号码。
其中，验证请求即为用户在呼叫电话时终端发送的会话建立信令。
例如，如该终端为手机，用户通过IMS网络拨打一些电话号码，若该电话号码不是该当前运营商网络内预先客制化的电话号码或是SIM卡支持的电话号码，则IMS会判断该短号码是否为紧急号码并将判断结果返回给当前终端，然后UE会发起MO INVITE信令即会话建立信令给验证服务器。
终端接收该验证服务器基于该验证请求返回的响应信息。
例如，当验证服务器收到会话建立信令后会返回一个响应信息380 Alternative Service信令，终端接收该响应信息。
终端根据该响应信息确定通讯标识类。
例如，具体可以如下：根据该类型标识符确定所述通讯标识类型，识别所述类型标识符的前缀信息，然后，根据所述前缀信息确定所述通信标识类型。终端接收到的响应信息380 Alternative Service信令携带参数Contact URI，可以根据参数Contact URI的前缀信息去判断通讯标识的类型，例如，当参数Contact URI携带有urn:service:sos前缀时，IMS网络匹配到这些短号码是紧急号码。
终端根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。
其中，网络制式网络制式就是网络的类型。例如，2G、3G、4G以及5G为不同的网络制式。
例如，具体可以如下：根据所述通讯标识类型、及所述通讯标识，发起电路域回落，注册到2G/3G网络。当该通讯标识类型为属于3GPP协议规定的紧急通讯标识时，基于2G/3G网络发送紧急拨号请求；当该通讯标识的类型不属于3GPP协议规定的紧急通讯标识，基于2G/3G网络发送普通拨号请求。当通话结束后，确定当前网络制式；当当前网络制式为2G/3G网络时，切换当前网络制式重新注册到VoLTE或VoWiFi。
其中，3GPP（The 3rd Generation Partnership Project，第三代合作伙伴计划）是为了定义完整的端到端***规范，确保符合行业需求，不同厂商之间实现无缝互操作以及为移动提供其所必需的全球规模，并且也为了实现GSM由2G网络到3G网络的平滑过渡的需求。
例如，例如，以步骤103中的例子为例，UE Modem（调制解调器）的IMS模块接收到响应信息后开始解析Contact URI中的内容，并将发起CSFB（Circuit Switched Fallback ，电路域回落），重新发起注册到2G/3G网络。若该电话号码为3GPP规定的紧急号码，则当前终端通过2G/3G网络发起紧急拨号。若该电话号码不是3GPP协议规定的紧急号码，则当前终端通过2G/3G网络发起普通拨号。
205、当通话结束后，终端确定当前网络制式。
206、当当前网络制式为2G/3G网络时，终端切换当前网络制式重新注册到VoLTE或VoWiFi。
本申请实施例在当终端处于VoLTE或VoWiFi网络下，接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求，接收该验证服务器基于该验证请求返回的响应信息，然后，根据该响应信息确定通讯标识类型，再然后，根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。该方案可以节省用户求救的时间，提高呼救效率。
根据上面实施例所描述的方法，以下将举一应用例作进一步详细说明。
如图3所示，UE启动，用户***运营商SIM卡，注册上VoLTE或是VoWiFi，然后进入拨号应用中的拨打应用界面后，输入（986/994/995）等短号码，并点击拨号键呼出此号码。如果当前呼出短号码未能匹配到手机或者SIM保存的紧急号码，则UE会发起MO INVITE信令给IMS网络，IMS网络回复UE的380 Alternative Service信令并携带参数Contact URI。UE Modem 的IMS模块接收到380 Alternative Service信令后开始解析Contact URI中的内容，并将发起CSFB回落，重新发起注册到2/3G网络。Modem解析380 Alternative Service信令中Contact URI的内容，并上报给Framework层，Framework层根据解析后的Contact URI的内容参数判断Contact类型，做如下处理：
若Contact URI为携带Category类型为3GPP协议支持的Contact类型，比如<urn:service:sos.police>，则会重新发起EMERGENCY_SETUP紧急呼叫流程，呼入到相应的紧急呼救中心。
若Contact URI为携带Category类型不是3GPP协议支持的Contact类型，比如<urn:service:sos.country-specific.pl.986>，将会发起重新发起普通电话SETUP流程，作为普通号码拨打出去。从而会在手机界面提示空号，从而避免用户因手机界面提示为紧急号码而多次拨打，耽误呼救时间。
为了便于更好的实施本申请实施例提供的呼叫的方法，在一些实施例中还提供了一种呼叫的装置，该呼叫的装置适用于终端，具体实现细节可以参考方法实施例中的说明。
在一些实施例中，还提供了一种呼叫的装置，该呼叫的装置具体可以集成在终端中。比如，可以以客户端的形式集成在客户端中，如图4所示，该呼叫的装置可以包括：处理单元301、接收单元302、确定单元303以及呼叫流程建立单元304，具体如下：
处理单元301，用于当终端处于VoLTE或VoWiFi网络下，接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求；
接收单元302，用于接收所验证服务器基于该验证请求返回的响应信息；
确定单元303，用于根据该响应信息确定通讯标识类型；
呼叫流程建立单元304，根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。
在一些实施例中，参考图5，该确定单元303包括识别子单元3031和第一确定子单元3032；
识别子单元3031，用于识别所述类型标识符的前缀信息；
第一确定子单元3032，用于根据所述前缀信息确定所述通信标识类型。
在一些实施例中，参考图5，该呼叫流程建立单元304包括第一呼叫子单元3041和第二呼叫子单元3042；
该第一呼叫子单元3041，用于当所述通讯标识类型为属于3GPP协议规定的紧急通讯标识时，基于2G/3G网络发送紧急拨号请求；
该第二呼叫子单元3042，用于当所述通讯标识的类型不属于3GPP协议规定的紧急通讯标识，基于2G/3G网络发送普通拨号请求。
在一些实施例中，参考图5，该装置还包括第二确定子单元305和切换子单元306；
该第二确定子单元305，用于当通话结束后，确定当前网络制式；
该切换子单元306，用于当该当前网络制式为2G/3G网络时，切换当前网络制式重新注册到VoLTE或VoWiFi。
由上可知，本申请实施例在当终端处于VoLTE或VoWiFi网络下，接收到用户输入的通讯标识触发的呼叫指令时，若该通讯标识不属于当前终端支持的通讯标识，则基于IMS网络向验证服务器发送验证请求，接收该验证服务器基于该验证请求返回的响应信息，然后，根据该响应信息确定通讯标识类型，再然后，根据该通讯标识类型、及该通讯标识，将该终端当前所连运营商网络的网络制式切换至目标网络制式发起呼叫流程。该方案可以节省用户求救的时间，提高呼救效率。
