Abstract

A method for performing cell reselection first determines a current cell selection quality value. The cell selection quality value is compared to a predetermined threshold. Measurements of neighboring cells are taken if the cell selection quality value is less than or equal to the predetermined threshold. Measurements can be taken of intra-frequency cells, inter-frequency cells, and inter-radio access technology cells. If a neighboring cell is found that is better than the current cell based on the measurements, then the better neighbor cell is reselected to.

Claims

1. A method for performing cell reselection, comprising:

determining a current cell selection quality value;

comparing the cell selection quality value to a predetermined threshold;

taking measurements of neighboring cells if the cell selection quality value is less than or equal to the predetermined threshold; and

if a neighboring cell better than the current cell is found based on the measurements, then reselecting to the better neighbor cell.
