The invention lies in state transitioning of a user equipment to take measurement reports for the purpose of reselecting between different priority cells. It aims to overcome the problem of how a user equipment (UE) in the UTRAN CELL-FACH state may reselect to the E-UTRAN cell. A UE determines that a neighbour cell is higher priority than a serving cell, measures neighbour cell signal strength in n>1 iterations, and analyzes them for reselecting from the serving cell to the neighbour cell. Each measurement iteration is spaced from one another by a time interval (e.g., 1 DRX) that is specific for the neighbour cell being higher priority. In various embodiments, the UE measures while in a Cell-PCH, URA-PCH or idle state/mode and the first iteration is taken at the first available measurement opportunity after transitioning to that state/mode. The UE reselects to the neighbour cell based on the analyzed signal strengths; in one embodiment the decision to reselect is without regard to signal quality of the serving cell; and in another the decision is without regard to whether a reselection condition remains satisfied for a specified time period Treselectionâ ¢ |
