A base station of a network is configured to transmit a first indication to a user equipment (UE) of a mapping of code points, wherein each code point maps to one or more corresponding aperiodic or semi-persistent positioning reference signals (PRS) to be transmitted from one or more transmission and reception points (TRP), transmit a second indication to the UE of a first one of the mapped code points to activate the one or more corresponding PRSs for reception at the UE and transmit the one or more activated PRSs to the UE.

Aperiodic and semi-persistent positioning reference signal and measurement gaps

A base station receives an alert indicating a geofenced area, and determines whether its coverage area is completely within the area. If so, the base station generates/sends a wireless emergency alert (WEA) to user equipment in the coverage area that does not indicate the area. Otherwise, the base station generates/sends a WEA that indicates the area. The base station sends action messages that indicate a periodicity and end time for the user equipment to determine whether its location is within the geofenced area, a lack of service time limit and lack of service action for the user equipment to perform after it has been without cellular service for the lack of service time limit, a lack of location time limit and lack of location action for the user equipment to perform if its location cannot be determined for the lack of location time limit, and/or that the WEA has ended.

Wireless emergency alert geofencing enhancements

Techniques are discussed herein for efficiently providing wireless emergency alerts (WEA) to a mobile device. The techniques include broadcasting a warning message from a base station in a wireless network within a cell for the base station and including an interior cell or exterior cell indication and a geographic area description for an external cell. A receiving mobile device may then display the warning message to a user either unconditionally when an interior cell is indicated or after verifying the mobile device is located within the geographic area for an exterior cell. The wireless network may determine interior versus exterior cell status by determining interior cells to be wholly within the geographic area and exterior cells to be partly within the geographic area.

Methods and systems for efficient location support for wireless emergency alerts

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.

VoIP emergency call support

Disclosed are methods and systems for supporting positioning operations in a cellular communication network including locating a mobile device in response to an emergency event. In one particular implementation, a first position fix may be provided quickly by a mobile device and may be followed by a second, more accurate, position fix at a later time. In particular implementations, the first and second position fixes may be provided using the 3GPP Long Term Evolution (LTE) Positioning Protocol (LPP) as part of a single LPP transaction and may further be provided using a user plane or control plane location solution.

Methods and systems for returning an early positioning fix

An application executed within a mobile station to be triggered only by a network element, such as a mobile positioning center (MPC) or a Mobile Center (MC). The network element is coupled to a base station. The network element is responsible for authorizing an application that is either resident within the mobile station or that is run in a device that is resident elsewhere in the network. The mobile station communicates with the network element over a communication session through the base station and other infrastructure components. The mobile station initiates a mobile originated positioning session over a second communication session with a positioning assistance server.

Location based service (LBS) system, method and apparatus for triggering of mobile station LBS applications

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.

Control plane location solution to support wireless access

Disclosed is a method and apparatus enabling positioning processes performed by user equipment. The method may include initiating a voice call over a first wireless communications network using a first radio access technology (RAT). The method may also include a connection between the user equipment and a second wireless communications network using a second RAT being placed into an idle state. The method may also include participating in a control plane positioning process with the second wireless communications network during the voice call over the first wireless communications network.

System and method for enabling mobile device location services during an emergency call

Techniques for supporting positioning are described. In an example implementation, a method for use in determining a position of a mobile station is provided, wherein a network-based computing device receives a message from a mobile station, the message indicating an identity of a transmitter device from which the mobile device has received at least one signal; and identifies at least one civil location estimate based at least in part on the message; the at least one civil location estimate representing an estimated location of the mobile device.

Positioning of a wireless device

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.

Location reporting with secure user plane location (SUPL)

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.

Method and apparatus for performing session info query for user plane location

VOIP emergency call support

Systems and methods for requesting and providing assistance data for a satellite positioning system are described herein. A method as described herein includes receiving, at a base station over a wireless communication link, a first message from a mobile station, wherein the first message comprises a first field identifying requested assistance data associated with a first Satellite Positioning System (SPS) and a second field identifying a requested format of the requested assistance data, and wherein the requested assistance data are available in a plurality of formats that includes the requested format; and transmitting a second message from the base station to the mobile station over the wireless communication link, wherein the second message includes the requested assistance data in the requested format.
