An apparatus for controlling a user equipment, the apparatus comprising a processing system arranged to: determine that a neighbour cell is a higher priority cell than a serving cell; measure signal strength received from the neighbour cell; and analyze the measured signal strengths for reselecting the user equipment from the serving cell to the neighbour cell, characterised in that: the measurement comprises measuring signal strength received from the neighbour cell in n iterations each spaced from one another by a time interval specific for the case in which the neighbour cell is the higher priority cell, in which n is an integer greater than one; and the analysis comprises analysing the n measured signal strengths for reselecting the user equipment from the serving cell to the neighbour cell, wherein the neighbour cell is a higher priority frequency layer cell or a higher priority radio access technology cell, and the serving cell is a UTRAN cell, wherein signal strength is measured across the n iterations while the user equipment is in one of a Cell-PCH state, URA-PCH state or idle mode with the UTRAN serving cell, and wherein a first one of the n iterations measures signal strength on a first available measurement opportunity after transitioning to the said one of the Cell-PCH state, URA-PCH state or idle mode. determine that a neighbour cell is a higher priority cell than a serving cell; measure signal strength received from the neighbour cell; and analyze the measured signal strengths for reselecting the user equipment from the serving cell to the neighbour cell, characterised in that: the measurement comprises measuring signal strength received from the neighbour cell in n iterations each spaced from one another by a time interval specific for the case in which the neighbour cell is the higher priority cell, in which n is an integer greater than one; and the analysis comprises analysing the n measured signal strengths for reselecting the user equipment from the serving cell to the neighbour cell, wherein the neighbour cell is a higher priority frequency layer cell or a higher priority radio access technology cell, and the serving cell is a UTRAN cell, wherein signal strength is measured across the n iterations while the user equipment is in one of a Cell-PCH state, URA-PCH state or idle mode with the UTRAN serving cell, and wherein a first one of the n iterations measures signal strength on a first available measurement opportunity after transitioning to the said one of the Cell-PCH state, URA-PCH state or idle mode. the measurement comprises measuring signal strength received from the neighbour cell in n iterations each spaced from one another by a time interval specific for the case in which the neighbour cell is the higher priority cell, in which n is an integer greater than one; and the analysis comprises analysing the n measured signal strengths for reselecting the user equipment from the serving cell to the neighbour cell, wherein the neighbour cell is a higher priority frequency layer cell or a higher priority radio access technology cell, and the serving cell is a UTRAN cell, wherein signal strength is measured across the n iterations while the user equipment is in one of a Cell-PCH state, URA-PCH state or idle mode with the UTRAN serving cell, and wherein a first one of the n iterations measures signal strength on a first available measurement opportunity after transitioning to the said one of the Cell-PCH state, URA-PCH state or idle mode.
