12.1 General

The SS uses the reset MS positioning stored information procedure to command the MS to reset the already acquired MS POSITIONING information in preparation for subsequent test procedures.

Figure 12: RESET MS POSITIONING STORED INFORMATION

12.2 Procedure

The SS requests the MS to reset the stored MS positioning information mode by transmitting a RESET MS POSITIONING STORED INFORMATION message.

When MS receives RESET MS POSITIONING STORED INFORMATION message then the MS shall:

– if the IE "MS Positioning Technology" has the value ‘AGPS’: discard any stored GPS reference time, reference position, and any other aiding data obtained or derived previously (e.g. expected ranges and Doppler).

– if the IE "MS Positioning Technology" has the value ‘AGNSS’:

– discard any stored GPS and GANSS reference time, reference position, and any other aiding data obtained or derived previously (e.g. expected ranges and Doppler);

– temporarily disable any sensor data (if applicable) that can aid the positioning for the duration of the subsequent positioning procedure.

– otherwise: ignore the message.
