Title:
TECHNIQUES TO SUPPORT EMERGENCY SERVICES
Document Type and Number:
WIPO Patent Application WO/2016/160112
Kind Code:
A3
Abstract:
Methods, systems, and devices are described for wireless communication to enable a UE to establish emergency services (e.g., IMS emergency calls) over WLAN (e.g., Wi-Fi) in 3GPP networks. Such mechanisms may help ensure that an ePDG capable of supporting emergency services is selected. Further, such mechanisms may help ensure that an appropriately located ePDG is selected. For example, the selected ePDG may be located in the visiting public land mobile network (VPLMN) for a roaming UE so that IMS emergency calls are routed appropriately. Selection of the ePDG may be under control of the network with which the UE is establishing connectivity for the emergency call, namely the VPLMN, as opposed to the home PLMN (HPLMN), for example. Such mechanisms may rely on knowledge that the connectivity being established is for emergency services, as well as other information regarding the UE, such as a current location of the UE.
