AI summary

A computer implemented method of handling threshold value of an antenna performance parameter of an antenna of a telecommunication network. A default antenna performance parameter threshold value of the antenna is obtained (301); a second antenna performance parameter threshold value for the antenna is determined(303) based on the default antenna performance parameter threshold value and loss information related to the antenna, or based on gradually testing antenna performance parameter threshold values; and the second antenna performance parameter threshold value is taken (304) into use for the antenna.
