Description

为终端提供紧急号码的方法和装置 技术领域
本公开涉及移动通信领域中信息管理技术，例如涉及一种为终端提供紧急号码的方法和装置。
背景技术
无线保真(Wireless Fidelity，WiFi)网络是一种能够将个人电脑、手持设备(如平板电脑(Pad)、手机)等终端，以无线方式互相连接的技术。WiFi在无线局域网(Wireless Local Area Network，WLAN)的范畴是指“无线相容性认证”，实质上是一种商业认证，同时也是一种无线联网技术。以前人们需要通过网线连接电脑从而实现联网，然而，WiFi可实现通过无线电波来联网。其中，常见的是无线路由器，在无线路由器发射的有效电波覆盖范围内都可以采用WiFi连接方式进行联网，如果该无线路由器连接有非对称数字用户线路(Asymmetric Digital Subscriber Line，ADSL)或者其它的上网线路，则无线路由器又被称为“热点”。
WiFi最主要的优势在于不需要布线，因此非常适合移动办公用户，并且，由于无线路由器发射信号功率低于100mw，即低于手机发射功率，所以WiFi上网也是相对安全健康的。由于WiFi的频段在全世界范围内是无需任何电信运营执照的，因此，WLAN无线设备提供了一个全世界范围内都可以使用的、费用极其低廉的且数据带宽极高的无线空中接口。
长期演进(Long term Evolution，LTE)网络是第三代(3rd Generation，3G)移动通信网络的演进，移动用户设备或终端(User Equipment，UE)在2G或3G网络下，语音业务主要是在电路交换(Circuit Switched，CS)域上实现，然而在LTE第四代(4G)移动通信网络下，只有分组交换(Packet Switch，PS)域，没有CS域。因此，LTE移动UE需要采用基于PS域的LTE语音业务(Voice over LTE，VoLTE)技术，从而实现基于LTE 4G网络下的语音业务。然而，随着支持WiFi语音(Voice over WiFi，VoWiFi)业务的终端出现，VoWiFi成为了VoLTE业务的有效补充，并遵循第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)制定的标准。
紧急呼叫是移动通信系统中特有的一种话音业务功能，即使移动终端设置了限制呼出和未插入用户识别模块(如，SIM卡)的情况下，只要在移动网络覆盖的区域内，当用户拨打紧急号码如：110或者119等后，呼叫会转到相应的紧急呼叫中心如警察局或消防队等，整个紧急呼叫系统的运行需要由电信运营商和公安、消防等紧急服务机构共同协作完成。在3GPP LTE网络中，移动管理单元(Mobility Management Entity，MME)可以发送本地的紧急号码给UE，UE保存本地的紧急号码，并在需要发起紧急呼叫时使用；然而在VoWiFi下，还没有网络侧为UE提供紧急号码的方法。这样，如果UE优先接入WLAN网络，则无法获取紧急号码；而且从部分UE的实现过程来看，即使UE曾经接入过LTE网络，或UE从MME接收过紧急号码，当UE再接入到WLAN网络时，也没有保存这些紧急号码。那么，当UE没有保存紧急号码时，就无法通过紧急呼叫的方式拨打紧急号码，从而无法实现紧急呼叫功能。
