Abstract
Methods and apparatuses for cell evaluation by a mobile terminal in a cellular network. A base station (100A, 100B) of a cell (102A, 102B) estimates values of an Expected User Throughput, EUT, for a series of candidate Reference Signal Quality, RSQ, values, and broadcasts (1:1A, 1:1B) the estimated EUTvalues as EUT information in the cell. The mobile terminal (104) is then able to evaluate (1:2-1:4) the cell for cell selection or re-selection based on the broadcasted EUT information.

A method in a base station providing radio coverage in a cell, for supporting cell evaluation for mobile terminals in a cellular network, the method comprising:
- determining a set of cell-specific parameters pertaining to data throughput in the cell;
- estimating values of an Expected User Throughput (EUT) for a series of candidate Reference Signal Quality (RSQ) values, based on the determined set of cell-specific parameters;
- and
- broadcasting the estimated EUT values as EUT information in the cell, thereby enabling mobile terminals to evaluate the cell for cell selection or re-selection based on the broadcasted EUT information.
A base station configured to provide radio coverage in a cell and support cell evaluation for mobile terminals in a cellular network, the base station comprising:
- a determining unit adapted to determine a set of cell-specific parameters (Pm) pertaining to data throughput in the cell;
- an estimating unit adapted to estimate values of an Expected User Throughput (EUT) for a series of candidate Reference Signal Quality (RSQ) values, based on the determined set of cell-specific parameters;
- and
- a broadcasting unit adapted to broadcast the estimated EUT values as EUT information in the cell, thereby enabling mobile terminals to evaluate the cell for cell selection or re-selection based on the broadcasted EUT information.
A method in a mobile terminal for cell evaluation in a cellular network, the method comprising:
- reading Expected User Throughput (EUT) information broadcasted from a base station providing radio coverage in a cell, said EUT information comprising cell-specific EUT values for a series of candidate Reference Signal Quality (RSQ) values;
- determining from the EUT information a valid EUT value that corresponds to an RSQ value measured on reference signals from the base station;
- and
- evaluating the cell for cell selection or re-selection based on the determined valid EUT value.
A mobile terminal configured to perform cell evaluation in a cellular network, the mobile terminal comprising:
- a reading unit adapted to read Expected User Throughput (EUT) information broadcasted from a base station providing radio coverage in a cell, said EUT information comprising cell-specific EUT values for a series of candidate Reference Signal Quality (RSQ) values;
- and
- an evaluating unit adapted to determine from the EUT information a valid EUT value that corresponds to an RSQ value measured on reference signals from the base station, and to evaluate the cell for cell selection or re-selection based on the determined valid EUT value.
