  1. Lauri WirolaLocation and Commerce, Nokia ICL-GNSS 2011, 29-June-2011
  2. Outline case for standardized location technologies location standards categories brief history current state and deployment status location standards state-of-the-art
  3. Technology challenge with(out) any connectivitymust work everywhere environment is not an excuse fast – time-to-first-fix
  4. Why standards bolts and nuts – interoperability is essential make money through licensing
  5. Space of standardized positioning technologies in use today 95% <150m Availability 67% <50mremote rural Network-Based A-GPS Methods sub-urban (ECID, TDOA) cityindoors Accuracy 1m 3 10 30 100 300 1km 3km 10km
  6. control plane vs. user plane two ways of carrying positioning signaling to the device control plane – integral part of the cellular network  low bandwidth  high integrity and security  use case cases limited to e-call, law & enforcement and network planning/monitoring user plane – works on top of the data connectivity provided by the physical network  high bandwidth  potential issues with integrity  de-facto method of providing position information to location-based value-added services
  7. architecture – big picture Protocols: Control Plane: RRLP/RRC/LPP User Plane: SUPL GNSS satellite GSM, UMTS, LTE (BSS, RNC, MME) Location Server - Network maintenance (SMLC) (e.g. cell-id database) - Network control WARN Assistance data services (GMLC) Location-based services Authorities
  8. 3GPP Radio Resource Location Protocol Rel-5/8OMA Secure User Plane Location Rel 1.0/2.0
  9. In the beginning history of location standards dates back to the late 90’s  work in GSM, AMPS, TDMA and CDMA domains UMTS followed a few years later nowadays GSM, UMTS and LTE positioning work done in 3GPP 3GPP2 taking care of CDMA/CDMA2000 networks
  10. Radio Resource LCS Protocol today the de-facto standardized positioning protocol is RRLP Rel-5 control plane positioning protocol for GSM practically in every mobile phone supports  AGPS (Assisted GPS) with GPS L1 C/A support  E-OTD (Enhanced Observed Time Difference) Rel-7 added Galileo and Rel-8 the rest of the GNSSs
  11. RRLP contents (Rel-7 onwards) Assistance Data E-OTD Assistance GPS Assistance GANSS Assistance Reference BTS Reference Time Common Assistance Data Reference Location Reference Time BTSs to measure -estimated OTDs DGPS Reference Location - RTDs Navigation Model Ionosphere Model - positions Ionosphere Model Earth-Orientation parameters UTC Model Almanac Generic Assistance Data Acquisition Assistance Inter-GNSS time model Real-Time Integrity DGANSS Ephemeris Extension Navigation model Real-Time Integrity Data Bit Assistance Reference Measurement Almanac UTC model Ephemeris Extension Auxialiary Information
  12. User Plane large majority of positioning assistance is today carried over the User Plane connection Open Mobile Alliance : Secure User Plane Location  User Plane wrapper for RRLP  provides security, authentication, privacy, charging and roaming  works over the data connection in 3GPP networks SUPL Rel 1.0 deployed in hundreds of millions devices globally
  13. OMA Secure User Plane Location Rel 3.03GPP LTE Positition Protocol Rel-9/10OMA LTE Positioning Protocol Extensions Rel 1.0
  14. LTE Positioning Protocol, LPP in autumn 2009 3GPP started the latest push for location services control plane positioning protocol for LTE (3.9G) and LTE-Advanced (4G) networks LPP was designed from day one to be  true GNSS  self-contained (AGNSS, ECID, OTDOA)  to do the bare minimum to support emergency, law&enforcement and network maintetance use cases (but nothing more!)
  15. LTE Positioning Protocol Extensions 3GPP knew that a wide number of emerging technologies were out-of-scope to support future development 3GPP decided to include extension containers to the LPP messages Open Mobile Alliance started work on LPP Extensions Rel 1.0 early 2010 standard is now in candidate status waiting for approval
  16. Vision for LPP Extensions to bring all the already standardized technologies under the same umbrella  basic AGNSS  enhanced Cell ID  hyperbolic time-based methods to bring the potential of professional-grade GNSS to the mass markets, including  Real-Time Kinematics  Precise Point Positioning take first steps in standardizing indoor-capable positioning methods
  17. Assisted GNSS in LPPe Rel 1.0 x 10 -3 Citymarket car park; Test 1; 8th Jan 2007 : Fixed solution 4 continuous carrier phase assistance 2 Validation in 25 s. East North Up  accuracy 0 Fixed Baseline error (m) -2  multiple reference stations -4  reference station mobility -6 -8  periodic session control -10 0 200 400 600 800 1000 1200 1400 local ionosphere corrections Time (s)  accuracy  also on periodic basis  also geomagnetic storm warnings
  18. Assisted GNSS in LPPe Rel 1.0 local troposphere corrections  accuracy  either delays or surface parameters  mapping functions altitude assistance  availability SV mechanics  time-to-first-fix  mass, solar panel reflectivity, solar radiation pressure navigation model degradation  integrity differential code biases  accuracy
  19. Cellular methods Enhanced Cell ID  GSM, UMTS, LTE  base station position, Tx power, antenna gain, azimuth, beam width, frequency drift Time Difference of Arrival  E-OTD  OTDOA  OTDOA-IPDL
  20. Non-cellular methods WLAN radiomaps  locations (indoor and civic support), coverage area, Tx power tags/beacons  support for carrying locations of sets of tags/beacons  RFID, BT Low Energy motion state delivery
  21. Secure User Plane Location 3.0 OMA SUPL Rel 3.0 is the preferred User Plane wrapper for LPPe Rel 1.0 adds on top of SUPL 1.0  geographic and temporal triggers (SUPL 2.0)  streaming of assistance data (SUPL 3.0)  locally discovered assistance/positioning server (SUPL 3.0)  support for WLAN data bearer (SUPL 3.0)

  24. Key takeaways standardized positioning technologies (AGNSS, Enhanced Cell ID, TDOA-methods) are backbone technologies for location services OMA LPP Extensions 1.0 and OMA SUPL 3.0 push the envelope of standardized positioning technologies predict that after the latest push there will be a quiet period to give time for markets to evolve in the coming years the emphasis is on standardizing the indoor positioning methods
