Location services based on the location of mobile devices are becoming increasingly widespread. SUPL (Secure User Plane
Location) employs user plane data bearers for transferring location assistance information such as gps assistance data, and
for carrying positioning technology-related protocols between mobile terminal and the network. SUPL is intended as an
alternative and complement to the existing standards based on signalling in the mobile network control plane.
