Emergency circuit-mode call support
First Claim
1. User equipment (UE), comprising:
- a transceiver; and
a processor coupled to the transceiver and configured to;
establish an emergency circuit-mode call with a wireless network, wherein the emergency circuit-mode call is routed using a first location server based on a serving cell identity for the UE;
interact with a second location server accessed by the first location server using Mobile Location Protocol or Roaming Location Protocol; and
perform user plane location with the second location server during the emergency circuit-mode call to obtain a position estimate for the UE.

Abstract
Techniques to support emergency circuit-mode 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 establishes a circuit-mode call with a wireless network for emergency services. The UE interacts with a location server indicated by the wireless network. The UE performs user plane location with the location server during the circuit-mode call to obtain a position estimate for the UE. The UE communicates with a PSAP, which may be selected based on the position estimate, for the emergency circuit-mode call. The UE may perform positioning with the location server to obtain an updated position estimate for the UE, e.g., whenever requested by the PSAP.
