Abstract: Apparatus and methods for determining a location estimate of a mobile device based on an extended set of assistance data are presented. The extended assistance data includes assistance data for base stations, such as cellular base stations and access points, not expected to be viewable by the mobile device in a (current) first geographical area but expected to be viewable by the mobile device in a (future) second geographical area. By seeding the mobile device with assistance data expected to be useful in the future, the network reduces messaging between the network and mobile device and battery consumption by the mobile device.

Abstract: An apparatus and method for determining a position of a mobile station based on terrestrial assistance data from a first wireless network to which the mobile station is not attached. That is, the mobile station is able to receive terrestrial assistance from a first wireless network and use the terrestrial assistance data to obtain location information, such as timing measurements, from the first wireless network and determine its position while not attached to the first wireless network. The first wireless network may be a network to which the mobile station is subscribed and can attach.

Abstract: Techniques for supporting location services with a streamlined location service layer are described. In one design, a terminal may receive a location service request from an application that is internal or external to the terminal The terminal may exchange at least one message with a location server to establish an extended location session of a particular duration via the streamlined location service layer. The terminal can thereafter obtain location service from the location server at any time within the particular duration of the extended location session, e.g., whenever a location request is received from the application. The terminal may obtain location service any number of times and at any time during the extended location session. The terminal or application may emulate a more complex location service based on location information received from all of the times in which location service is obtained by the terminal.

Abstract: Techniques for supporting handover of an emergency call between wireless networks are described. A UE may communicate with a first wireless network (e.g., a 3GPP E-UTRAN) for an emergency call and may receive an indication to perform handover to a second wireless network (e.g., a CDMA2000 1xRTT network). In an aspect, the UE may send a message including an emergency indication (an emergency global number, or a reserved emergency number, or some other indication) to initiate handover to the second wireless network. A designated network entity may recognize the emergency call based on the emergency indication and may map the emergency indication to a local emergency number or an Emergency Session Transfer Number for SRVCC (E-STN-SR), which may be used to establish a new incoming call leg to a network server anchoring the emergency call. The UE may then communicate with the second wireless network via the network server for the emergency call after handover.

Abstract: Apparatus and methods for performing mobile-based positioning in a wireless communications system are presented. A position estimate is computed based on assistance data intended for a first position method. The mobile device ignores if a second positioning method is not specifically supported by a network and computes a position estimate using the second position method and a subset of assistance data intended for the first positioning method, which is supported by the network and is different from the second positioning method.

Abstract: Techniques for supporting triggered location services are described. In one design, at least one location related measurement for a terminal may be obtained and used to detect for a trigger event. For an equidistance triggered service, a trigger event may be declared if the distance traveled by the terminal exceeds a predefined distance. For a relative terminal to terminal triggered service, a trigger event may be declared if the terminal is inside or outside, or enters, or leaves a moving geographical target area defined by a reference terminal. For a velocity triggered service, a trigger event may be declared if the maximum velocity of the terminal exceeds a predefined velocity. For a time-distance-velocity combination triggered service, a trigger event may be declared based on distance traveled by the terminal, velocity of the terminal, and time since the last report. For all services, a report may be sent if a trigger event has occurred.

Abstract: Techniques for maintaining location continuity for a user equipment (UE) following handover are described. The UE communicates with a first radio access network (RAN) and is served by a source serving node and a source location server prior to handover. The UE communicates with a second RAN and is served by a target serving node and a target location server after the handover. In an aspect, location continuity may be maintained for the UE by transferring an identity of the target serving node to a location server during handover of the UE. In one design, the target serving node sends its identity to the target location server, which updates a Location and Routing Function (LRF) serving the UE. In another design, for handover from packet-switched domain to circuit-switched domain, the source serving node sends the target serving node identity to the source location server, which updates the LRF.

Abstract: Techniques for performing location logging and location and time based filtering are described. In one design of location logging, a terminal periodically determines its location, e.g., during its paging slots. The terminal determines whether there is a change in its location and stores its location if a change in location is detected. In one design of location and time based filtering, the terminal obtains a location and time criterion with a target area and a time period. The terminal determines its location during the time period, e.g., based on the location log. The terminal evaluates the location and time criterion based on the target area and its location during the time period, e.g., based on at least one sector ID for the target area and one or more sector IDs for its location. The terminal determines whether to download and/or present broadcast information based on the result of the evaluation.

Abstract: Apparatus and methods to support Voice Call Continuity (VCC) for emergency calls in a wireless access environment are operable to receive, at a serving domain, a message containing emergency and domain transfer information from a user equipment (UE). The apparatus and methods are further operable to determine a need for emergency call origination or domain transfer based on the emergency and domain transfer information. Additionally, the apparatus and methods are operable to perform the emergency call origination or the domain transfer based on the determining.

Abstract: Techniques for supporting a control plane solution for location services and positioning are described. In an aspect, an Evolved Serving Mobile Location Center (E-SMLC) may communicate with a Mobility Management Entity (MME) to support location services and positioning for a UE. In one design, the E-SMLC may receive a location request from the MME, perform a positioning procedure with the UE in response to the location request, and send a location response to the MME after completing the positioning procedure. For a UE-assisted or UE-based positioning procedure, the E-SMLC may send a downlink positioning message to the UE via the MME and may receive an uplink positioning message from the UE via the MME. For a network-based positioning procedure, the E-SMLC may send a network positioning request message to an eNB via the MME and may receive a network positioning response message from the eNB via the MME.

Abstract: Techniques for routing an emergency call originated by a mobile station via a femto access point (FAP) in a wireless network and for locating the mobile station are described. In an aspect, the emergency call may be routed to an appropriate emergency center based on location information for the FAP. In one design, the location information for the FAP may include a macro cell identity (ID) and/or a macro Mobile Switching Center (MSC) ID determined based on the FAP location. The macro cell ID and/or the macro MSC ID may be assigned to the FAP and used to access a database, which may store routing information for emergency centers versus cell IDs and MSC IDs. In another design, the location information for the FAP may include a location estimate for the FAP. The location estimate may be used to access a geographic database, which may store routing information for emergency centers for different geographic areas.

Abstract: 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: In an aspect, a generic positioning protocol (GPP) may be used to support satellite-based positioning methods and terrestrial-based positioning methods for different access types. A tenninal may exchange a first GPP message with first information for a positioning method and an access type supported by GPP. The terminal may exchange a second GPP message with second infonmation for the positioning method and the access type. Each GPP message may include at least one position element, and each position element may be for a specific positioning method. The tenninal may obtain a position estimate for itself based on the second information. In another aspect, positioning may be performed based on measurements for cells of different wireless access types. In yet another aspect, received transmission times may be transformed to converted times based on common timing, which may be applicable for multiple wireless access types.

Abstract: Methods and apparatuses are provided for supporting multiple positioning protocol versions within wireless communication networks.

Abstract: Techniques for querying for information on location sessions in a user plane location architecture are described. In an aspect, a location server may send a query message to a terminal to query for information on active location sessions, e.g., when at least one location session for periodic triggered service or area event triggered service is deemed to be active. The terminal may return a response message containing a list of session identifiers (IDs) for the active location sessions, parameters for the active location sessions, capabilities of the terminal, etc. The location server may compare the information received from the terminal and information stored at the location server. The location server may terminate each location session deemed to be active at only the terminal or only the location server. The location server may restart or terminate each location session having inconsistent parameters at the terminal and the location server.
