VOIP EMERGENCY CALL SUPPORT
First Claim
1. A method for establishing a packet-based emergency call by a user equipment (UE), comprising:
- receiving an indication of an emergency call;
performing network attach with a radio access network (RAN) for packet-based access with an indication that the packet-based access is for emergency services; and
establishing a packet-based call, using the packet-based access, to perform the emergency call.

Abstract
Techniques to support emergency voice-over-Internet Protocol (VoIP) calls are described. The techniques may be used for various 3GPP and 3GPP2 networks, various location architectures, and various types of User Equipment (UE). A UE communicates with a visited network to send a request to establish an emergency VoIP call. The UE interacts with a location server instructed by the visited network to obtain a first position estimate for the UE. The UE performs call setup via the visited network to establish the emergency VoIP call with a PSAP, which may be selected based on the first position estimate. The UE may thereafter perform positioning with the location server to obtain an updated position estimate for the UE, e.g., if requested by the PSAP.
