Celizion's Patent
  (Title : Network Based Location Measurement Method and system Using PSMM data)
Key Concept of PSMM solution provide more accurate accuracy to Non-GPS Phone
  (Legacy Phone) without any S/W and H/W change phone itself
It is needed to change CDMA2000 1X Mobile System (MSC, BSC, BTS) according to 3GPP2
  standard
According to LBS call statistics, LBS service will be activated by accuracy improvement because
  of low accuracy of Cell-ID positioning solution method which provide very poor accuracy between
  several hundred meter and several kilo meter
Discrimination of Our Company's Non-GPS Phone Positioning solution
No change phone software and hardware
Epochal Accuracy improvement than previous Cell-ID Positioning Method
Reuse pCell database which already constructed for pCell indoor solution
Small Affected by reduced Pilot Phase resolution than triangulation positioning method which
  mainly influenced by Pilot phase resolution
SK Telecom for CDMA2000 1X Wireless Mobile System named PSMM which adopted Celizion
  Engine at October 2006
