An exemplary method of controlling communications that may include high speed downlink packet access (HSDPA) traffic includes setting a first power limit below an allowable power limit. A second power limit is set that is below the first power limit. A determination is made whether there is any HSDPA traffic. The first power limit is selected for non-HSDPA traffic when there is no HSDPA traffic. The second power limit is selected for non-HSDPA traffic when there is HSDPA traffic.

A method of controlling a base station, a network controller, a base station, a telecommunications network and a computer program product are disclosed. A method of controlling a base station () in a mobile telecommunications network () comprises the steps of: (i) determining whether a base station within the mobile telecommunications network is not supporting user equipment () and, if so, then (ii) signalling the base station to reduce its transmission power. An assessment is made as to whether a base station is currently supporting user equipment. If a base station is currently supporting user equipment, then that base station is unlikely to be a candidate to have its power reduced since support to that user equipment needs to be maintained. However, if a base station is not supporting user equipment, then that base station would appear to be a likely candidate for transmission power reduction, thereby saving power in the network at those locations where it is possible to do so.

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.
