GeoLENs™ Secure User Plane Location (SUPL):

Our SUPL Location Platform (SLP) works with SUPL-enabled terminals to provide User Plane caller locating in any network. Deployed in multiple operator networks, Andrew’s SLP supports A-GPS and Cell ID technologies to deliver User Plane support for many LBS applications. Andrew’s well-established SET interoperability program has tested dozens of SUPL-enabled handsets from major vendors, assuring operators compatibility with a wide selection of compatible handsets.

GeoLENs™ Secure User Plane—SUPL Location Methods

A-GPS based positioning

Assisted-GPS (A-GPS) is a handset-based mobile locating method fundamentally based on GPS locating technology but functionally distributed between the mobile and a centralized server. Mobiles must be specially equipped to receive GPS signals from multiple GPS satellites in order to make measurements of the signals from GPS satellites and relay this information or their calculated position through the mobile network to the SMLC/SAS/SLP software (iSAS: Control Plane, SUPL: User Plane implementations). In cases where the mobile does not compute its own location from GPS data, the SMLC/SAS/SLP uses GPS data relayed from the target mobile to compute the mobile's position. Once determined, the position can be sent to a gateway mobile location center (GMLC) or SUPL Location Platform (SLP) for distribution to the application that originated the location request. A-GPS is a supplemental form of GPS whereby GPS satellite position data is sent from the SMLC/SAS/SLP through the mobile network to the mobile to assist the mobile in determining which GPS satellites it should attempt to acquire. This supplemental data is intended to:

Speed the mobile's satellite signal acquisition process.
Increase the mobile's ability to receive signals from the target GPS satellites.

A-GPS is intended to reduce latency and improve other location performance when a mobile's view of GPS satellites is obscured. That can occur when the caller is in a building, in a vehicle, or in an "urban canyon." Although A-GPS does improve overall locating performance, accuracy, latency, and yield performance can be subject to degradation if a mobile's view of GPS satellites is obscured.

Cell ID Positioning:

Allows basic location services to be deployed using existing handsets and network capabilities and kick start market interest and revenues.

Cell sector location coordinates passed to the application
Can be accomplished using a standalone Gateway Mobile Location Center (GMLC) that connects to MSC and HLR using ATI
SMLC based when deployed
Can be configured to provide mid point of the cell if desired
