Abstract:
A method for cell reselection from a serving cell to another cell in a radio access network covering a geographical area divided into a plurality of cells, the method comprising: attempting to reselect to a first other cell with a higher rank value than the serving cell; setting up a channel on the first other cell and initiating a completion period; conditional on the completion period expiring before the first other cell is identified as being a suitable cell, receiving cell measurements for cells and creating a cell ranking list of the cells based on rank values of the cells; conditional on a second other cell having a higher rank value than the serving cell or first other cell, attempting to reselect to the second other cell.
