The present invention provides a method and an apparatus for allocating frequency bands associated with a multi-band network across a first and a second cell in a communications system. The method comprises determining a load parameter associated with the first and second cells in the communications system (500,610), selecting a target cell among the first and second cells for a mobile wireless device for transferring the mobile wireless device from a first frequency band to a second frequency band based on the load parameter of the first and second cells (505,620,630). In one embodiment, selection of an appropriate frequency band may be realized for a mobile wireless device in a multi-band network based on measurements of pilot channel properties and a load parameter to take into account a cell load of a target set of cells for an inter-frequency handover. This integration of the cell load for ranking, selection and transfer of user to a target cell from an overloaded cell may prevent unnecessary inter-frequency handover of users to cells with a relatively higher load, resulting in an increase in overall system capacity as well as quality of service.
