a successful re-establishment to another cell.
3 . The method according to claim 1 further comprising:
measuring a serving beam for a certain time interval indicated with the wireless communication network; and
calculating a combination of the measurement results.
4 . The method according to claim 1 further comprising: utilizing the updated one or more parameters in further communication with the wireless cor munication network.
5 . The method according to claim 1 further comprising:
attaching with the measurement results an indication whether a forced update flag was enabled with the wireless communication network or not.
6 . An apparatus, comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform at least the following:
measure signals of one or more beams of a cell of a wireless communication network for handover;
obtain information of an identity of the one or more beams from the measured signals;
store the measurement results and the identity of the one or more beams;
determine whether to update one or more parameters related to the handover;
based on a beam operating as a serving beam for the cell is changing to target beam:
update the one or more parameters based on a leaving condition for a handover applies or a flag indicating a forced update for a pair of the serving beam and the target beam is set; and
otherwise postpone updating of the one or more parameters if an entering condition for a handover applies until the leaving condition for the handover applies; and
send the measurement results and the identity of the one or more beams to the wireless communication network when at least one predetermined condition is fulfilled.
7 . The apparatus according to claim 6 wherein the at least one predetermined condition is one or more of the following:
