Introduction
The System Assisted Mobile Positioning through Satellite (SAMPS)
Teleservice defines the procedures and signaling for a
handset-based positioning service. SAMPS supports various
location-based services. SAMPS addresses subscriber-positioning
requirements in TIA/EIA-136 based networks and TIA/EIA-553-A based
networks by utilizing the existing Global Positioning System (GPS)
infrastructure. SAMPS utilizes the data and signaling capabilities
of TIA/EIA-136 and this specification to enhance the performance of
GPS-equipped Mobile Stations (MSs) by providing "GPS
assistance."
The procedures, signaling and transport for operation of SAMPS
on digital channels (DCCH, DTC) are specified in TIA/EIA-136-740.
This specification defines the procedures and signaling and
transport for operation of SAMPS on analog channels (ACC, AVC).
