具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1示出了本申请实施例的系统框架示意图，包括终端、第一网络和互联网协议地址多媒体系统(IP Multimedia Subsystem，IMS)网络。
其中，终端可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端等，本申请实施例对此并不限定。
第一网络可以是通信系统中网络，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、无线局域网(wireless local area network，WLAN)、第五代无线通信系统(the fifth Generation，5G)或未来的无线通信系统等中的网络。
第一网络可以包括核心网网元和接入网网元。
其中，接入网网元可以是全球移动通讯(global system of mobile communication，GSM)系统或码分多址(code division multiple access，CDMA)中的基站控制器(base station controller,BSC)，也可以是WCDMA中的无线节点控制器(radio node controller,RNC)，还可以是LTE中的演进型基站(evolved node B，eNB或e-NodeB),还可以是5G网络中的新型基站(例如，evolved LTE Node B，eLTE NB，或者next generantion node B，gNB)，或者可以是未来无线通信系统中的基站，该接入网网元130可以是共享接入网网元，例如可以是多个公共陆地移动网络(public land mobile network，PLMN)共享的接入网网元。
核心网网元可以是接入和移动管理功能(access and mobility management function，AMF)网元、移动性管理(mobility management entity，MME)网元、会话管理功能(session management function,SMF)网元、用户面功能(User plane function,UPF)网元、服务网关(serving gateway，SGW)、公用数据网网关(packet data networks gateway，PGW)、策略控制功能(policy control function，PCF)网元、归属用户服务器(home subscriber server，HSS)也可以称为签约数据库或者通用分组无线服务(general packet radio service，GPRS)业务支撑节点(serving GPRS support node，SGSN)、网关通用分组无线服务支持节点(Gateway general packet radio service support node，GGSN)。
在本申请实施例中，终端可以向第一网络发起注册流程，然后终端向第一网络发起建立紧急业务的相关会话，第一网络根据紧急业务的相关会话建立紧急业务的隧道，终端通过第一网络建立的隧道向IMS网络发起紧急业务请求消息，IMS根据紧急业务请求消息 为终端提供紧急服务。
图2示出了本申请实施例中的网络通信示意图，第一网络和第二网络可以互相通信，其中，第一网络包括：第一网络的核心网网元、第一类型的接入网网元以及与第一网络的核心网网元连接的第二类型的接入网网元，第一网络的核心网网元、第一类型的接入网网元以及与第一网络的核心网网元连接的第二类型的接入网网元组合模式可以称为混合组网，即混合组网为同一核心网网元连接两种不同类型的接入网网元。第二网络包括：第二网络的核心网网元以及与第二网络的核心网网元连接的第二类型的接入网网元。例如，第一网络可以是5G网络，第二网络可以是4G网络，本申请实施例对此不作限定。
例如，第一类型的接入网网元可以为5G接入网网元(也可以称为NG RAN)，第二类型的接入网网元可以为EUTRAN。例如，第一网络的核心网网元可以为5G核心(fifth generation core，5GC)网设备，第二网络的核心网网元可以为分组核心演进(evolved packet core，EPC)设备。
在实际应用中，有可能第一类型的接入网网元不支持紧急业务，第二类型的接入网网元支持紧急业务，当终端在第一类型的接入网网元发起紧急业务时，如何保证终端能够有效的发起紧急业务，网络如何为终端提供紧急服务，是本申请实施例需要解决的问题。
例如，在本申请实施例中，当第一类型的接入网网元不支持紧急业务，第二类型的接入网网元支持紧急业务，当终端在第一类型的接入网网元的覆盖范围内发起紧急业务时，由于第一类型的接入网网元不支持紧急业务，则第一类型的接入网网元可以将终端移动至支持紧急业务的第二类型的接入网网元。可以将终端移动至与第一网络的核心网网元连接的第二类型的接入网网元，或者也可以将终端移动至与第二网络的核心网连接的第二类型的接入网网元。进一步地，当第一网络的核心网网网元支持紧急业务时，优先将终端移动至第一网络的第二类型的接入网网元；当第一网络的核心网网元不支持紧急业务时，将终端移动至第二网络的第二类型的接入网网元，这样可以提高终端发起紧急业务的准确性。
下面结合附图描述本申请实施例中的处理业务的方法。
图3示出了本申请实施例的处理业务的方法100。该方法100包括：
S110，终端接收第一指示信息，所述第一指示信息用于指示第一网络的至少一个类型的接入网网元是否支持紧急业务。可选地，第一网络可以包括第一网络的核心网网元和第一网络的第一类型的接入网网元和第一网络的第二类型的接入网网元。
应理解，至少一个类型可以为多个类型，例如包括第一类型和第二类型。
可选地，第一类型的接入网网元向终端发送第一指示信息，S110，包括：终端接收第一类型的接入网网元发送的第一指示信息，第一指示信息用于指示第一类型的接入网网元是否支持紧急业务；可选地，所述第一类型的接入网网元向终端发送广播消息，所述广播消息包括所述第一指示信息，终端接收第一类型的接入网网元发送的广播消息，在所述广播消息获取所述第一指示信息。
可选地，第二类型的接入网网元向终端发送第一指示信息，S110，包括：终端接收第二类型的接入网网元发送的第一指示信息，所述第一指示信息用于指示第二类型的接入网网元是否支持紧急业务；可选地，所述第二类型的接入网网元向终端发送广播消息，所述广播消息包括所述第一指示信息，终端接收第二类型的接入网网元发送的广播消息，在所述广播消息获取所述第一指示信息。
可选地，第一网络的核心网网元向终端发送第一指示信息，S110，包括：终端接收第一网络的核心网网元发送的第一指示信息，所述第一指示信息用于指示所述第一网络的至少一个类型的接入网网元是否支持紧急业务，例如，第一指示信息用于指示所述第一网络的第一类型是否支持紧急业务，和/或，所述第一指示信息用于指示所述第一网络的第二类型的接入网网元是否支持所述紧急业务，即可以只指示其中的一个类型的接入网网元是否支持所述紧急业务，也可以同时指示两个类型的接入网网元是否支持紧急业务。本申请实施例对此不作限定。终端可以向第一网络的核心网网元发送注册请求消息，注册请求消息用于向第一网络的核心网网元请求注册，可选地，第一网络的核心网网元向终端发送第一指示信息，包括：第一网络的核心网网元向终端发送注册响应消息，所述注册响应消息包括第一指示信息，终端接收第一网络的核心网网元发送的注册响应消息，终端在所述注册响应消息中获取所述第一指示信息。
可选地，紧急业务也可以称为紧急服务(emergency service)，紧急业务可以为IMS紧急呼叫业务。
应理解，至少一个类型可以包括多个类型，本申请实施例中为了方面描述仅以第一类型和第二类型举例说明。
在一种可能的实现中，在网络规划的过程中，可以将不同类的接入网网元规划在同一个跟踪区(tracking area，TA)列表(list)中，当终端在同一个TA列表包括TA内移动时，终端只需要在首次接入网络时所在的TA向网络设备发起注册请求消息，网络设备可以在向终端返回注册响应消息时，在注册响应消息中携带在当前TA内网络侧是否支持紧急业务的指示信息，终端可以根据该指示信息确定是否发起紧急服务，但是，有可能在同一TA列表中不同的TA内的有的类型的接入网网元支持紧急服务，有的类型的接入网元不支持紧急服务，例如，当终端在当前第一TA时，指示信息指示第一类型的接入网网元支持紧急服务，当终端从当前的第一TA移动到下一个第二TA时，有可能在下一个第二TA第一类型的接入网网元不支持紧急服务，但是终端仍然以在为第二TA第一类型的接入网网元是支持紧急服务的，因此，终端在第二TA仍然向第一类型的接入网网元发送紧急业务请求，这样第一类型的接入网网元不会响应终端的请求，造成发起紧急业务的失败，在本申请实施例，第一类型的接入网网元可以发送第一指示信息来向终端指示自身是否支持紧急业务，第二类型的接入网网元也可以发送第一指示信息来向终端指示自身是否支持紧急业务，这样，当终端移动在第一类型的接入网网元时可以监听到第一类型的接入网网元发送的第一指示信息，当终端移动的第二类型的接入网网元时可以监听到第二类型的接入网网元发送的第一指示信息，这样，可以使得终端在当前的TA内能够准确的发起紧急业务，例如，当终端在数据连接态时，可以向支持的紧急服务的接入网网元发起紧急业务，不向不支持紧急服务的接入网网元发起紧急业务。
更进一步地，第一网络的核心网网元可以向终端发送第一指示信息，第一指示信息可以指示第一网络的第一类型的接入网网元是否支持紧急业务也可以指示第二类型的接入网网元是否支持紧急业务，这样，当终端移动到任何一个类型的接入网网元的覆盖范围内时，都可以根据第一指示信息确定当前所在的接入网网元是否支持紧急业务，从而终端可以准确的发起紧急业务，避免紧急业务的失败。
S120，所述终端接收第二指示信息，所述第二指示信息用于指示所述第一网络的核心 网网元是否支持紧急业务。
可选地，所述第一网络的核心网网元向所述终端发送第二指示信息，S120，包括：所述终端接收第一网络的核心网网元发送的第二指示信息。可选地，所述第一网络的核心网网元向所述终端发送第二指示信息，包括：第一网络的核心网网元向终端发送注册响应消息，所述注册响应消息包括所述第二指示信息。所述终端接收第一网络的核心网网元发送的第二指示信息，包括：所述终端接收第一网络的核心网网元发送的注册响应消息，所述终端在注册响应消息中获取所述第二指示信息。
可选地，第二指示信息具体用于指示所述核心网网元在所述终端当前所在的TA列表范围是否支持紧急业务。在一种可能的实现中，当终端在首次接入网络时，在终端所在的TA向核心网网元发起注册请求消息，核心网网元可以在向终端返回注册响应消息，在注册响应消息中携带在当前TA，核心网网元是否支持紧急业务的指示信息，终端可以根据该指示信息确定是否发起紧急业务，但是，当终端从当前的第一TA移动到下一个第二TA时，有可能在下一个第二TA核心网网元不支持紧急服务，但是终端仍然以为核心网网元是支持紧急服务的，因此，终端在第二TA仍然向网络发起紧急业务，核心网元是是不会响应终端的紧急业务，因此会造成发起紧急业务的失败，在本申请实施例，不是指示核心网网元在单个TA是否支持，而是指示核心网网元在TA列表是否支持，这样，当终端移动的到任何一个TA时都可以准确得确定是否发起紧急业务，从而可以提高发起紧急业务的准确性。
应理解，第二指示信息可以指示所述核心网网元在所述终端当前所在的TA列表范围是否支持紧急业务，可以理解为：第二指示信息指示所述第一网络的核心网网元在当前所在的TA列表范围内的都支持紧急业务或者都不支持紧急业务。
可选地，第二指示信息也可以指示第一网络的核心网元在整网范围内是否支持紧急业务。
S130，所述终端根据所述第一指示信息和/或所述第二指示信息发起所述紧急业务。
可选地，终端可以根据第一指示信息和/或第二指示信息确定是否发起紧急业务。具体分为终端处于空闲态和数据连接态的情形。例如，当终端处于空闲态时，分为以下几种情况描述：
第一种情况，S130，包括：若所述终端根据所述第一指示信息确定所述终端当前所在的第一类型的第一接入网网元支持所述紧急业务，且若所述终端根据第二指示信息确定所述终端所在的核心网网元支持所述紧急业务，则所述终端根据所述第一指示信息和所述第二指示信息通过所述第一接入网网元发起所述紧急业务。
第二种情况，S130，包括：若所述终端根据所述第一指示信息确定所述终端当前所在的所述第一网络的第一类型的接入网网元不支持所述紧急业务，和/或，若所述终端根据第二指示信息确定所述第一网络的核心网网元不支持所述紧急业务，则所述终端重选到第二类型的接入网网元，并通过所述第二类型的接入网网元发起所述紧急业务。
具体来说，所述终端根据所述第一指示信息确定所述终端当前所在的所述第一网络的第一类型的接入网网元不支持所述紧急业务，并且若所述终端根据第二指示信息确定所述第一网络的核心网网元不支持所述紧急业务，则所述终端重选到第二网络的第二类型的接入网网元，并通过所述第二网络的第二类型的接入网网元发起所述紧急业务。
第三种情况，S130，包括：若所述终端根据所述第一指示信息确定所述终端当前所在的所述第一网络的第一类型的接入网网元不支持所述紧急业务，并且若所述终端根据第二指示信息确定所述第一网络的核心网网元支持所述紧急业务，则所述终端重选到所述第一网络的第二类型的接入网网元，并通过所述第一网络的第二类型的接入网网元发起所述紧急业务。
