The present invention provides methods for selecting a handover algorithm. The methods may include selecting the handover algorithm for a mobile unit based on at least one measurement indicative of a network state. The methods may also include receiving information indicative of the handover algorithm selected based on the measurement(s) indicative of the network state.

Selecting a handover algorithm

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.

Establishing or releasing a radio connection between a mobile and a cell for wireless telecommunications

QoS scheduling is used for handling multiple data flows in packet switched cellular systems, especially in a packet switched mobile telecommunication system, wherein the scheduling mechanism of a specific cell is coupled with the scheduling mechanism of at least one second cell, in particular by transferring data between the specific cell and at least one second cell comprising a status information concerning data flow within the specific cell.
