Refer to follow document to want to know of LD solution in more detail
Location Detector H/W shall be installed each subway station
LD Server shall be instructed LD database initially and updated whenever LD reassign
Whenever A-GPS call attempt to try find friend and find my location, PPM data will
transfer to
ILIS(LD) server which operate integrated Indoor solution algorithm
including LD,
if LD algorithm find matching database, then report the result to PDE.
The purpose of LD solution report correct name of subway station
SK
