Abstract: A location server, such as a Serving Mobile Location Center (SMLC) or E-SMLC and mobile terminal selectively implement the reliable transport mechanism used in, e.g., LPP or LPPe protocols, thereby decreasing unnecessary delays. The reliable transport mechanism may be selectively implemented by not requiring an acknowledgement for specific messages, such as an unsolicited assistance data message. When assistance data is solicited, however, the responsive assistance data message includes an acknowledgement request as per the reliable transport mechanism.

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.
