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 • 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 • 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
