Mortive - It is claimed as one of the most effective technology which enable network operators to offer Location Based Services for their subscribers speedily and economically. As the empiric revealed the reluctant of network operators to implement LBS is basically because of the cost and complexity of modifying Control Plane (C-Plane, some refers as positioning) network elements and protocols. Thus SUPL facilitates network providers to achieve this with least impact on C-Plane.
Overview - SUPL was developed by OMA (Open Mobile Alliance - http://www.openmobilealliance.org/), which is organized to bring in open standards that ensures interoperability across devices in LBS industry.Therefore it supports location identification regardless of the location server used by the mobile carrier. Further, it has designed to facilitate A-GPS (Assisted GPS), which is regarded as one of the most efficient positioning mechanism.
Architecture of SUPL consists of two elements, viz. SET (SUPL Enabled Terminal) and SLP (SUPL location Platform). Set is a mobile phone or PDA configured to support SUPL transactions.SLP is a server that handles user authentications, LB requests, roaming and charging etc.
