Abstract

A method of handling minimization of drive tests, hereafter called MDT, for a mobile device is disclosed. The method comprises receiving a MDT measurement configuration from a first RAT, starting a timer for a MDT measurement logging corresponding to a timer value in the MDT measurement configuration, and keeping the timer running when the mobile device performs an inter-RAT procedure to move from the first RAT to a second RAT.

Claims

1. A method of handling minimization of drive tests, hereafter called MDT, for a mobile device, the method comprising:

receiving a MDT measurement configuration from a first radio access technology (RAT);

starting a timer for a MDT measurement logging corresponding to a timer value in the MDT measurement configuration; and

keeping the timer running when the mobile device performs an inter-RAT procedure to move from the first RAT to a second RAT.

2. The method of claim 1, wherein keeping the timer running when the mobile device performs the inter-RAT procedure to move from the first RAT to the second RAT comprises:

when the mobile device performs the inter-RAT procedure to move from the first RAT to the second RAT, not stopping the timer.

3. The method of claim 1, further comprising:

stopping the MDT measurement logging when the timer expires.

4. A method of handling minimization of drive tests, hereafter called MDT, for a mobile device, the method comprising:

receiving a MDT measurement configuration from a first radio access technology (RAT);

starting a timer for a MDT measurement logging corresponding to a timer value in the MDT measurement configuration; and

starting/restarting the timer when the mobile device performs an inter-RAT procedure to move from the first RAT to a second RAT.

5. The method of claim 4, wherein starting/restarting the timer when the mobile device performs the inter-RAT procedure to move from the first RAT to the second RAT comprises:

when the mobile device performs the inter-RAT procedure to move from the first RAT to the second RAT and stops the timer that has started, starting/restarting the timer with a remaining timer value of the started timer.

6. The method of claim 4, further comprising:

stopping the MDT measurement logging when the timer expires.
