<p>The present invention relates to a cellular radio communications system in which each radio connection is allocated a dedicated radio channel. The quality of the radio connection over the radio channel is checked regularly and compared with a threshold value (RLT_UL, RLT_DL). If the connection quality is found to lie beneath the threshold value, the radio connection is terminated and the radio channel can then be reused for a new connection. According to the present invention, the threshold value is changed in accordance with the traffic load in the cell concerned. When the traffic load in the cell is high, i.e. only a few channels are available, the radio connection is terminated when the quality reaches a given level of impairment. The radio channel can then be used for a new radio connection. On the other hand, when the traffic load is low, the quality of the connection must be still poorer than the quality in a high load situation in order for the channel to be released.</p> |
