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 |
