Patent ID: 8909229

Claim:
An apparatus for use in controlling a user equipment, the apparatus comprising: a processing system comprising at least one processor and a memory storing a set of computer instructions, in which the processing system is arranged to: determine that a neighbor cell is a higher priority cell than a serving cell; measure signal strength received from the neighbor cell in n iterations each spaced from one another by a time interval specific for the case in which the neighbor cell is the higher priority cell than the serving cell, in which n is an integer greater than one and the time interval is shorter than a corresponding interval for a different case in which the neighbor cell is assigned a priority which is not higher than the serving cell; and analyze the n measured signal strengths for reselecting a user equipment from the serving cell to the neighbor cell; wherein: the time interval comprises one discontinuous reception (DRX) period which the user equipment utilizes with the serving cell which is a UTRAN cell; the neighbor cell is a higher priority frequency layer cell or a higher priority radio access technology cell; the 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 for a first one of the n iterations, the signal strength is measured during a first available measurement opportunity after the user equipment transitions to the said one of the Cell-PCH state, URA-PCH state or idle mode.
