Andrew's Compatibility Testing for Handset Vendors Supports Caller Location Applications

(Business News & Technology News, 28 Apr 2008)

As new mobile devices come to market that support location-based services, network operators increasingly favor solutions that are based on Secure User Plane Location (SUPL) protocols. Helping ensure compatibility, Andrew Wireless Solutions, a CommScope Inc. division focused on communications systems and products, is successfully supporting handset vendors' SUPL-capable devices through interoperability testing on the Andrew Geometrix SUPL Location Platform, paving the way for wireless operators to reliably integrate location-based services into their networks.

"Interoperability of handsets is critical for the success of any SUPL-based application," says John Baker, Vice President, Technical Marketing, Wireless Network Solutions, Andrew. "To ensure this critical interoperability and to provide maximum flexibility to our Geometrix SUPL Location Platform customers, Andrew initiated a comprehensive handset testing program more than a year ago. The program is available to any handset vendor wishing to test its devices for interoperability and, to date, most major handset vendors have participated. Our work in this area will help speed development and implementation of location based-services that will benefit consumers and businesses."

Secure User Plane Location is a streamlined alternative to the Control Plane location method, a network-level means used in all previous location systems for finding callers. Control Plane location systems interconnect with the equipment that comprises and operates wireless networks and the signaling systems within the network. For example, when a 911 call is placed, Control Plane location systems calculate the location of the caller and forward this information to emergency responders—a reliable but less direct way to locate wireless devices.

SUPL, however, leverages location capabilities that are becoming more prevalent in wireless handsets, especially Assisted-GPS. With SUPL, an application can directly request any handset's location by means of a short message to the handset. There is no need to interact at the network level, or Control Plane, enabling greater flexibility in meeting the growing demands for Assisted-GPS location services.

Operators install Andrew's Geometrix SUPL Location Platform to support critical functions such as authentication, privacy protection, and handset assistance with GPS and other functions. To help operators pursing the greatest flexibility and market responsiveness, Andrew's Geometrix SUPL Location Platform is designed to support all SUPL-enabled handsets that meet industry standards.

"Andrew expects that an increasing number of operators will implement SUPL and SUPL-based location systems to support location-based services in GSM, UMTS, and next-generation IP networks including LTE and WiMAX," Baker says. "Several of the participating handset manufacturers we have already tested have been referred to the Andrew SUPL program by network operators implementing our solution."
