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.
Abstract:
Techniques for supporting periodic and other location services with Secure User Plane Location (SUPL) and other location architectures are described. The techniques can provide position estimates for a SUPL enabled terminal (SET) to a SUPL agent periodically and/or based on trigger events. A Home SUPL Location Platform (H-SLP) receives from the SUPL agent a request for position estimates for the SET. The H-SLP starts a SUPL location session with the SET. For each of at least one reporting event during the location session, the H-SLP obtains a position estimate for the SET and sends the position estimate to the SUPL agent. The position estimate may be derived by the SET and sent to the H-SLP. Alternatively, the position estimate may be derived by the H-SLP based on measurements from the SET.
Abstract:
Techniques to support emergency circuit-mode calls are described. The techniques may be used for various 3 GPP and 3 GPP 2 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.
Abstract:
Techniques for performing registration in parallel with call establishment to reduce delay are described. A user equipment (UE) performs registration with a communication network, e.g., in response to a user placing an emergency call. The UE establishes the call in parallel with performing registration. The UE updates the call with information (e.g., verified UE identity and/or call back information) obtained from the registration by sending the information to a called entity/party such as a Public Safety Answering Point (PSAP) selected for the emergency call. The UE sends a first message to initiate registration, a second message to initiate establishment of the call, and a third message to update the call with the information obtained from the registration. The established call may be associated with the registration based on a common source IP address in the first, second and third messages and common dialogue information in the second and third messages.

Abstract:
Un procedimiento para dar soporte a servicios de ubicación (500), que comprende: establecer una sesión de ubicación genérica entre un terminal y un servidor de ubicación, comprendiendo dicho establecimiento transmitir o recibir uno o más mensajes; y participar en una pluralidad de actividades de posicionamiento entre el terminal y el servidor de ubicación, donde cada una de las actividades de posicionamiento es cualquiera de una pluralidad de tipos de actividades de posicionamiento soportadas por el terminal y el servidor de ubicación (512), en el que cada actividad de posicionamiento posterior se puede iniciar en cualquier momento durante la sesión de ubicación genérica sin la necesidad de intercambiar mensajes para establecer una nueva sesión de ubicación para la actividad.
