D.1 Test Method

In this clause the terms GNSS and A-GNSS also include the cases where the only satellite system used is GPS unless otherwise stated.

Each test is performed in the following manner:

a) Setup the required test conditions.

b) Start each repetition after having applied the message ‘RESET UE POSITIONING STORED INFORMATION’. This ensures that each result is independent from the previous one.

c) Make the required measurement a repeated number of times. The results, measured, are simplified to:

good result, if the measured result is ≤ limit.

bad result, if the measured result is > limit

For the relevant A-GNSS test cases measure the 2D position and Time to First Fix (TTFF) a repeated number of times. Measure the 2D position and Time to First Fix (if applicable) repeated times. Start each repetition after having applied the message ‘RESET UE POSITIONING STORED INFORMATION’. This ensures that each result is independent from the previous one. The results, measured, are simplified to:

good result, if the 2D position and TTFF are ≤ limit.

bad result, if the 2D position or TTFF or both are > limit

d) Record the number of results (ns) and the number of bad results (ne)

e) Stop the test at a pass or a fail event.

f) Once the test is stopped, decide according to the pass fail decision rules (D.4.2)
