Patent ID: 8543117

Claim:
An apparatus for use in selecting cells to be measured by a user equipment, the apparatus comprising a processing system comprising at least one processor and a memory storing computer program code, the processing system being arranged to: store in the at least one memory a prioritized measurement list in which are represented at least two radio access technologies, each entry in the prioritized measurement list defining a unique combination of frequency layer and radio access technology for a serving cell and for neighbor cells; and based on at least signal strength of the serving cell, select from a neighbor list according to the prioritized measurement list a set of entries for measuring according to a selection rule, wherein the selection rule provides: for the case in which the signal strength of the serving cell is relatively high, the selected set is a first set of the prioritized measurement list; and for the case in which the signal strength of the serving cell is relatively low, the selected set is a second set of the prioritized measurement list, the second set excluding all frequency layers of the prioritized measurement list belonging to the radio access technology having a highest priority or alternatively a lowest priority, and the second set different from the first set.
