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.

Abstract: Techniques for supporting network-initiated location services for a terminal are described. A location server may not be able to reach the terminal in a normal manner in certain operating scenarios. The terminal may perform registration with the location server if the terminal determines that it may not be reachable by the location server in the normal manner. For the registration, the terminal may identify itself to the location server, instigate mutual authentication of the terminal and the location server, and provide an Internet Protocol (IP) address of the terminal to the location server. The terminal may perform registration with the location server whenever the IP address changes and/or periodically whenever a timer expires. The terminal may set the timer to a value received from the location server. The location server may use the IP address to send messages to the terminal for network-initiated location services.

Abstract: 100951 Techniques for supporting eCalls are described. In an aspect, an eCall indicator may be used to indicate an eCall being established. In one design, a terminal may generate a message including an eCall indicator and may send the message to originate an eCall. The eCall indicator may indicate (i) whether or not a call is an eCall or (ii) whether an eCall is initiated automatically by the terminal or manually by a user. In another aspect, a terminal may avoid sending signaling for mobility management and connection management to wireless networks except for eCalls and designated calls. The terminal may avoid performing location updating, performing registration, responding to paging requests, etc. The terminal may exchange signaling with a wireless network for an eCall initiated by the terminal. After the eCall is initiated, the terminal may perform location updating with the wireless network and call establishment for the eCall.

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 for efficiently performing network selection using information stored at a terminal are described herein. The terminal may store coverage information for previously detected wireless networks, cell information for previously detected cells in wireless networks, usage information for previously accessed wireless networks, availability information for previously detected wireless networks, almanac information for cells in wireless networks (e.g., information on cells available at different locations and information for acquiring the cells), and/or other information that may be useful for network selection. The terminal may select a wireless network to attempt acquisition based on the stored coverage information and its current location, the stored cell information and information for the current location (e.g., an identity of a cell detected at the current location), the stored usage information, the stored availability information, and/or the stored almanac information.

Abstract: A user equipment (UE) communicating with a radio access network (RAN) sends to a network entity (e.g., an MSC/SGSN) a request for periodic reporting of the UE location to a client entity. After the request is approved, the MSC/SGSN sends to the RAN signaling to initiate periodic location reporting for the UE. The RAN may request a positioning center (e.g., a SAS) to send assistance data to the UE. The RAN may coordinate and control the periodic location reporting or may pass the control over to the positioning center. For each location reporting, the UE sends location information (e.g., measurements made by the UE or a location estimate computed by the UE) to the RAN. The SAS computes a location estimate if the UE sends measurements. The RAN then sends the location estimate for the UE to the MSC/SGSN, which forwards the location estimate toward the client entity.

Abstract: Techniques for performing registration in parallel with call establishmen t to reduce delay are described. A user equipment (UE) performs registration with a communication network, e.g., in response to a user placing an emerge ncy call. The UE establishes the call in parallel with performing registrati on. The UE updates the call with information (e.g., verified UE identity and /or call back information) obtained from the registration by sending the inf ormation to a called entity/party such as a Public Safety Answering Point (P SAP) selected for the emergency call. The UE sends a first message to initia te registration, a second message to initiate establishment of the call, and a third message to update the call with the information obtained from the r egistration. The established call may be associated with the registration ba sed on a common source IP address in the first, second and third messages an d common dialogue information in the second and third messages.
