5.4.1 Reset UE Positioning Stored Information

5.4.1.1 General

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

5.4.1.2 Initiation

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

5.4.1.3 Reception of RESET UE POSITIONING STORED INFORMATION message by UE

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

1> if the IE "UE Positioning Technology" has the value ‘AGPS’:

2> discard any stored GPS reference time, reference position, and any other aiding data obtained or derived during the previous test instance (e.g. expected ranges and Doppler).

1> if the IE "UE Positioning Technology" has the value ‘AGNSS’:

2> 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);

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

1> otherwise:

2> ignore the message.

5.4.2 Update UE Location Information

Figure 5.4.2-1: Update UE Location Information procedure

5.4.2.1 General

The SS uses the Update UE Location information procedure to send positioning information to the UE and command it to store positioning information in preparation for subsequent test procedures.

5.4.2.2 Initiation

The SS requests the UE to store the positioning information contained in the message by transmitting a UPDATE UE LOCATION INFORMATION message.

5.4.2.3 Reception of UPDATE UE LOCATION INFORMATION message by UE

When UE receives UPDATE UE LOCATION INFORMATION message then the UE shall:

1> if the UE has location information values stored:

2> discard the stored location information:

1> store the received location information (ellipsoidPointWithAltitude) and maintain it until reception of RESET UE POSITIONING STORED INFORMATION or UPDATE UE LOCATION INFORMATION message. Information not supported by the UE may be discarded.
