Abstract
A handover or cell change procedure in a cellular radio communications system starts with mobile user terminal present in a serving cell and having multiple radio resources simultaneously allocated for communication with a base station of the cell. When there is a need for a cell change, the multiple radio resources are sequentially replaced with radio resources allocated to the terminal for communication with at least one base station having an associated cell different from the serving cell. This cell change procedure provides macro diversity without requiring the complexity of soft handover and has enhanced service coverage and handover robustness compared to hard handover.
