CELL RE-SELECTION IN A CELLULAR TELECOMMUNICATIONS NETWORK
First Claim
1. A method in a wireless cellular telecommunications device camped on a serving cell, the device storing a parameter obtained from a first cell, the method comprising:
- measuring an attribute of a signal received from a candidate UTRAN cell; and
,evaluating the candidate cell for re-selection,wherein, if a carrier frequency of the candidate cell matches a carrier frequency of the first cell, the evaluation of the candidate cell for re-selection is based on at least the measured attribute and the stored parameter, elsethe evaluation of the candidate cell for re-selection is performed without using the stored parameter.

Abstract
According to an aspect of the present invention, there is provided a method in a wireless cellular telecommunications device camped on a serving cell, the device storing a parameter obtained from a first cell. The method comprising: measuring an attribute of a signal received from a candidate cell; and, evaluating the candidate cell for re-selection. If a carrier frequency of the candidate cell matches a carrier frequency of the first cell, the evaluation of the candidate cell for re-selection is based on at least the measured attribute and the stored parameter, else the evaluation of the candidate cell for re-selection is performed without using the stored parameter. A device and computer readable medium are also provided.
