A target cell for handover of a User Equipment from a source cell in a Multi-Operator Core network is selected by storing the PLMN IDs of neighbor cells, identifying a best candidate neighbouring cell for handover from measurement reports sent by the User Equipment and comparing the stored PLMNID of the best candidate neighbouring cell with the PLMNID in use in the source cell. If the source and best candidate neighbouring cell PLMN IDs match then handover to the best candidate neighbouring cell is initiated, otherwise a handover to a next best candidate neighbouring cell with the same PLMNID as the source cell is initiated. The invention enables networks with different radio access network sharing arrangements or no sharing at all to co-exist and provide mobility of a User Equipment. The above may be implemented within small (e.g. femto) cells served by Home Node Bs. |
