Triggering pilot transmission for mobility measurements

4:

• The method according to claim 1, further comprising:
• receiving measurement reports from the WD;
• and in response thereto:
• dynamically updating the location dependent performance quality criterion based on the received measurement reports.

5:

• The method according to claim 1, further comprising:
• receiving a signal quality indicator from the WD, the signal quality indicator pertaining to signalling received by the WD from the RANN;
• and
• dynamically updating the location dependent performance quality criterion based on the received signal quality indicator.

7:

• The method according to claim 1, further comprising:
• estimating a signal quality indicator of the received signalling;
• and
• dynamically updating the location dependent performance quality location criterion based on the estimated signal quality indicator.

11:

• The method according to claim 5 further comprising:
• estimating a signal quality indicator of the received signalling;
• and
• dynamically updating the location dependent performance quality location criterion based on the estimated signal quality indicator,
• wherein the step of receiving said signal quality indicator from the WD is performed after the step of estimating said signal quality indicator of the received signalling.

20:

• The method according to claim 1, further comprising:
• receiving previous user traffic signalling indicative of at least one previous position of the WD and at least one previous performance quality metric of the WD;
• and
• wherein said location dependent performance quality criterion depends on said at least one previous position of the WD and said at least one previous performance quality metric of the WD.

22:

• A radio access network node (RANN) for triggering mobility measurements for a wireless device, the RANN being configurable to transmit using a set of transmission beams, the RANN comprising processing unit configured to:
• receive signalling from a wireless device (WD), wherein the user traffic signalling is indicative of a current position of the WD and a performance quality metric of the WD;
• and only in a case said performance quality metric fulfils a location dependent performance quality criterion:
• activate transmission of mobility pilot signals to the WD in at least one transmission beam in the set of transmission beams;
• and thereafter:
• instruct the WD to perform measurements on the at least one transmission beam.

23:

• A nontransitory computer readable storage medium comprising a computer program for triggering mobility measurements for a wireless device, the computer program comprising computer program code which, when run on a processing unit of a radio access network node (RANN) configurable to transmit using a set of transmission beams causes the processing unit to:
• receive signalling from a wireless device (WD), wherein the user traffic signalling is indicative of a current position of the WD and a performance quality metric of the WD;
• and only in a case said performance quality metric fulfils a location dependent performance quality criterion:
• activate transmission of mobility pilot signals to the WD in at least one transmission beam in the set of transmission beams;
• and thereafter:
• instruct the WD to perform measurements on the at least one transmission beam.
