Abstract
In an embodiment, a method for support of emergency services over WLAN access to 3GPP Evolved Packet Core EPC for unauthenticated Users includes, in response to a request to provide a user identity for access authentication, a User Equipment UE providing a specific NAI-based user identity having a realm part indicating unauthenticated access for emergency services. Also includes an authenticator, such as TWAN entity for Trusted WLAN access or ePDG for Untrusted WLAN access, routing a message from said UE, based on said realm part, towards a specific 3GPP AAA Server serving a domain dedicated to unauthenticated access for emergency services, the specific 3GPP AAA Server granting access to the UE, and providing specific authorization data that allow network access for emergency services to the UE.
