Abstract: Apparatus and methods to support emergency services sessions by network elements and by a wireless device are disclosed. The wireless device, when roaming to a visited country/region, queries a network-based server to obtain information for Public Land Mobile Networks (PLMNs) that support emergency services sessions via non-cellular wireless access in the visited country/region. The network-based server responds with a list of PLMNs from which the wireless device selects a PLMN. The wireless device further queries the network-based server to obtain information for evolved Packet Data Gateways (ePDGs) for a selected PLMN and receives from the network-based server a list of Internet Protocol (IP) addresses for ePDGs that support emergency services sessions via non-cellular wireless access for the selected PLMN. The wireless device further queries the network-based server for local numbers of the visited country for establishing emergency services sessions and receives a categorized list of local numbers for emergency services.

Abstract: Apparatus and methods to support emergency services through untrusted wireless networks by a user equipment (UE) are disclosed. The UE detects a request for emergency services to be provided via an untrusted wireless network. The UE de-registers from any non-emergency services and releases any existing PDN connections. The UE sends a request for emergency services to an evolved packet data gateway (ePDG) at an Internet Protocol (IP) address obtained from a table or from a domain name system (DNS) server. The request includes an indication for emergency services using a configuration attribute assigned to indicate emergency services. The UE receives from the ePDG an indication of support for emergency services in a reply to the request.

Abstract translation: 公开了通过用户设备（UE）通过不可信无线网络来支持紧急服务的装置和方法。 UE检测到经由不可信无线网络提供的紧急服务请求。 UE从任何非紧急服务器中取消注册，并释放任何现有的PDN连接。 UE从从表或从域名系统（DNS）服务器获得的因特网协议（IP）地址向发展的分组数据网关（ePDG）发送紧急服务请求。 该请求包括使用分配用于指示紧急服务的配置属性的紧急服务的指示。 UE在对请求的回复中从ePDG接收到对紧急服务的支持的指示。
