1. A method to select a cell in a mobile communications equipment (MCE) when transitioning from a connected mode state to an idle mode state, the MCE configurable for use in a cellular network, the method comprising: beginning state transition activity, the MCE currently in the connected mode state; identifying a set of UMTS-based candidate cells, wherein at least one of the set of candidate cells is a cell which is not currently supporting the connected mode state; storing information relating to at least one candidate cell which is not currently supporting the connected mode state arising from past data gathering by the MCE, the information gathered previous to state transition activity; selecting a candidate cell from the identified set of candidate cells that includes the at least one cell which is not currently supporting the connected mode state; and transitioning to an idle mode state from the connected mode state.
