ABSTRACT:
A method is provided of establishing or releasing a radio connection between a first mobile user station and a first cell for wireless telecommunications during a call with the first mobile user station. This is both whilst the call continues and dependent upon at least one predetermined criterion being met. This occurs in a network for wireless telecommunications handling calls with various data rates to mobile user stations such that some of the mobile user stations at a time have multiple radio connections to the network via multiple cells. A pilot signal is sent between the first cell and the first mobile user station. Received signal quality of the pilot signal between the first cell and the first mobile user station is detected. At least one predetermined criterion is selected dependent upon data rate of the call, and if it is determining that said signal quality of the pilot signal meets said at least one predetermined criterion, said radio connection is released or established.
