EMERGENCY CIRCUIT-MODE CALL SUPPORT |
摘要 |
<p>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.</p> |
