Techniques to enable emergency services in an unauthenticated state on wireless networks

摘要

An embodiment of the present invention provides a method of enabling emergency services in an unauthenticated state on wireless networks, comprising attempting Extensible Authentication Protocol (EAP) authentication with a public user account by a client whose identity indicates the need to place an emergency call, authenticating the client by a Subscription Service Provider Network's (SSPN's) authentication, authorization and accounting (AAA) server and providing keying material to an authenticator and supplicant, thereby securing wireless link, providing by the SSPN's AAA server a virtual local area network identification (VLAN ID) back to an access point (AP), performing by the AP or a distribution system (DS) infrastructure a per-user policing for the VLAN ID ensuring upper-limit on resource usage commensurate with an emergency call, and routing the emergency call to a Public Safety Answering Point (PSAP) by the SSPN's call manager.
