A gps over control plane

A-GPS over CONTROL Plane

  • There are existing GPS Assistance data messages already defined and they can be re-used

    • A-GPS over CONTROL plane has been standardised within 3GPP and 3GPP2, but these two solutions requires an upgrade of nearly all of the network elements and interfaces

  • 3GPP defined stage 1&2

    • Improvement of the Le interface: Completed Enhanced support for anonymity and user privacy: Completed

    • Enhanced support of roaming subscribers, inter GMLC Lr interface: on going

  • OMA Location group defines stage 3 protocols

    • MLP (mobile location protocol), RLP (roaming location protocol) and PCP (privacy checking protocol) already support or will support SIP-URI of the target mobile.

    • Note: SA2 does not specify external protocols and it works very closely with the OMA-LOC in order to insure consistency between requirements and protocols specifications owned by OMA.


  • User apps plane a gps today

    User/Apps Plane A-GPS - today

    • There are several proprietary implementations of A-GPS over USER plane already emerging in different markets

    • It would be beneficial to have one single standard forAssisted GPS over USER/Application plane instead of

      • WCDMA standard RRC messages ‘wrapped’ with a header

      • GSM standard RLP messages ‘wrapped’ in XML

      • IS95 / IS801 messages

  • There is a large body of interest from Operators and Suppliers

  • There are existing GPS Assistance data messages already defined


  • New wi a gps design goals

    New WI A-GPS Design Goals

    • Make full A-GPS functionality available with minimum network changes

    • Design to enable both Mobile Assisted and Mobile Based A-GPS

    • Utilise existing standards where available and possible

    • Open to enable other positioning technologies to utilise the mechanism

    User/Apps Plane A-GPS

    • AGPS over USER plane does not require an upgrade of a current IP capable network, so it is a lower cost solution and can be deployed rapidly

    • This solution

      • is able to protect investment effectively, because 3G and 2G systems could share a common network positioning platform and even Mobile devices

      • may reduce the burden on signaling network

      • is not dependent on the underlying infrastructure except for an (IP) connection and supports outbound roamers

      • can reuse existingdefinedprotocols

      • does not provide emergency call support
