Abstract:
Techniques described herein are directed toward enabling location support for 5G New Radio (NR) wireless access by a user equipment (UE) by utilizing existing LTE location support. More specifically, LTE positioning protocol (LPP) messages may be communicated between a UE with NR wireless access and a location server (e.g. an LMF) in a 5G Core Network via an NG-RAN. The LPP messages may support RAT-independent and E-UTRA position methods by the UE such as A-GNSS or OTDOA for E-UTRA. The location server may obtain OTDOA related information from eNBs and ng-eNBs supporting LTE wireless access. A UE may request measurement gaps from a 5G base station (e.g. gNB) in order to obtain measurements for RAT-independent and E-UTRA position methods and may request an idle period in order to obtain LTE timing needed for E-UTRA measurements.
Abstract:
Techniques are described for providing assistance data corresponding to a plurality of access points (APs). The techniques include, in part, providing assistance data to a mobile device. The assistance data comprises group data that is common among the plurality of APs. The group data is associated with a group identifier (ID). The techniques further include providing the group ID and a set of AP-specific information for at least one of the plurality of APs. The group data may include information corresponding to a common grid, common location area and/or common characteristics of the APs.
Abstract:
A method includes: receiving a request at a Secure User Plane Location (SUPL) Location Platform (SLP) for location-related service; producing a positioning method SUPL message that includes a posmethod parameter that includes a positioning protocol indicator indicating that SET capability transfer and positioning method selection are to be conducted in a positioning protocol layer; and sending the positioning method SUPL message from the SLP to a SUPL Enabled Terminal (SET) using a SUPL User Plane Location Protocol (ULP).
Abstract:
In aspects of the disclosure, a method, an apparatus, and a computer program product for wireless communication by a user equipment (UE) are provided. In one aspect, the UE associates with an access point of a wireless local area network which may be untrusted, obtains a list comprising a plurality of public land mobile network (PLMN) entries and one or more selection conditions associated with each one of the plurality of PLMN entries, and selects a PLMN from the list when the one or more selection conditions associated with the PLMN are satisfied. The UE may further discover an evolved packet data gateway (ePDG) for the selected PLMN using one or more fully qualified domain name (FQDN) rules for the selected PLMN. The UE may then attach to the selected PLMN using the discovered ePDG.
Abstract:
A mobile device includes: a transceiver configured to send and receive signals to and from a location-based services application server (LBS AS) and an access/location network (ALN); and a processor communicatively coupled to the processor and configured to: send, via the transceiver, a first identity for the mobile device to the LBS AS; send, via the transceiver, a second identity for the mobile device to the ALN, wherein the first identity and the second identity comprise a common identity for the mobile device; and obtain a location service from the LBS AS, or the ALN, or a combination thereof, via the transceiver.
Abstract:
Systems, methods, apparatuses, and computer-readable media for providing radio frequency interference (RFI) awareness assistance data to global navigation satellite system (GNSS) receivers are described. In some embodiments, a first method includes receiving at a location server RFI situational information. The first method further includes maintaining at least one time and location dependent database of an RFI situation. The first method further includes sending at least one assistance data message to at least one receiver including the RFI situational information. In another embodiment, a second method includes receiving RFI awareness assistance data from a location server. The second method further includes adapting a position location measurement according to the received RFI awareness assistance data. The second method further includes calculating a location of the receiver based at least in part on the adapted position location measurement.
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 are described for aligning heat map information more efficiently to an actual geometry of an area of interest. A sequence is generated corresponding to consecutive runs of included and/or excluded grid points. The sequence is provided to a device in addition to heat map information corresponding to a number of grid points. The provided heat map information may be compressed and/or may be assigned to grid points in a reoriented area overlaying the area of interest. The device uses the sequence to map the heat map information to grid points in an area. In one technique, information corresponding to inaccessible locations are excluded from the heat map.
Abstract:
Systems, methods, and devices are described for aligning heat map data more efficiently to actual geometry of an area of interest. Certain embodiments make use of reorienting a rectangular array of grid points in which an additional angle parameter is added to existing parameters for a rectangular heat map. For example, the grid points may be reoriented to form a shape resembling a parallelogram.
Abstract:
Systems, apparatus and methods for crowdsourcing measurements of wireless base stations, access points and/or other transmitters from a mobile device to a server are presented. A crowdsourcing request sent by a server to a mobile device may comprise control parameters and measurement parameters. Control parameters may determine when a mobile obtains and reports measurements and measurement parameters may determine which types of measurements a mobile device obtains. Control parameters may comprise trigger parameters for crowdsourcing activation, measurement, reporting and duration. Crowdsourcing may be instigated by a control server and reported to a different data server. Crowdsourcing may be anonymous and may comprise basic or advanced reporting.
