1 OMA Location Working Group Update Mike Loushine Senior Scientist / Program Manager Emerging Mobile Technologies Group Telcordia Applied Research May 11, 2010 Version 1.0

2 Outline  Disclaimer –  This presentation is not an official OMA presentation.  SUPL 3.0 Status  3GPP LPP and OMA LPPe Status

3 Data Gateway: used for SUPL “traffic” SMS Gateway: used for SUPL service initiation for network initiated SUPL applications SET - SUPL Enabled Terminal SUPL Server - SUPL Location Platform (SLP) OMA SUPL High-level Architecture

4 SUPL 3.0 Objectives  Evolve SUPL 2.0 in the following areas  Location Support for LTE  Improved Location for IP Emergency Calls  Improved Location performance  Triggered Location Enhancement  Improved Indoor Location Accuracy  SET to SET Location (Terminal to Terminal)  Authentication Enhancements  Privacy Enhancements  Additional access networks  Support for Extended Location Information

5 SUPL 3.0 Status  Highlights of the Requirements (1)  The protocol SHALL support IETF “Revised Civic Location Format for Presence Information Data Format Location Object (PIDF-LO)” [RFC5139] Location info format.  SUPL SHALL support SLP service discovery.  SUPL SHALL support delivery of indoor context information from the SET to the H-SLP.  SUPL SHALL support emergency location for unauthenticated SET.

6 SUPL 3.0 Status  Highlights of the Requirements (2)  SUPL SHALL support the conveyance of a location URI from the SET to the SLP. The SLP MAY use the location URI as an additional source of location information.  SUPL SHALL support extended location information including, for instance, motion state (walking, running, driving, etc.) and SET orientation information.

8 3GPP LPP – LTE Positioning Protocol  Operates on a transaction basis between a target device and a server  3GPP Evolved Packet Solution  Target Device – UE  Server – MME  OMA SUPL 2.0  Target Device – SUPL Enabled Terminal (SET)  Server – SUPL Location Platform (SLP)  Transaction Types  Exchange of positioning capabilities  Transfer of assistance data  Transfer of location information (positioning measurements and/or position estimate) Reference: 3GPP TS V1.0.0 ( )

9 LPP Version 1 and 2 Reference: 3GPP TS V1.0.0 ( )

10 OMA LPPe –Work Areas  AGNSS extensions  High accuracy methods including Precise Point Positioning and Real-Time Kinematics  Atmosphere models, etc.  Radio Network-based positioning extensions  Radiomaps for cellular and non- cellular networks (coverage area models – collection and positioning)  Fingerprinting methods (fingerprint collection and positioning) for cellular and non-cellular access types  SET-based positioning, including:  SET based OTDOA and  SET based E-CID for LTE and other access types  radio network assistance data over a broader geographic area  Support of other access types (e.g. Wi-Fi)  SET to SET positioning extensions  Compliment (but not duplicate) service layer support in SUPL 3.0  Extension of existing terrestrial RF positioning methods to positioning of one SET by other SETs (e.g. a SET measures signals from another SET)  A-GNSS support between SETs – e.g. SET to SET conveyance of assistance data

11 LPP3 Status  Highlights of the Requirements (in development)  LPPe SHALL support fixed access types such as Cable, DSL, LAN, etc.  LPPe SHALL support altitude assistance for improved availability and altitude performance.  LPPe SHALL support measurements and assistance for high- accuracy relative positioning.  LPPe SHALL support delivery of indoor context information to the UE.  LPPe SHALL support delivery of indoor context information from the UE to an appropriate entity in the network.
