NETWORK ELEMENTS, CELLULAR COMMUNICATION SYSTEM AND METHODS THEREFOR

摘要

A localised billing plan for a mobile wireless communication unit (107) in a cellular communication system (100) can be preserved when the unit (107) relocates from a source cell (105) to a target cell (114) by including billing information in the handover message. The billing information comprises a billing Service Area Identity relating to the source cell (105) which may be included in a last visited cell list. The target cell (114) may prioritise the source cell (105) for a subsequent handout. The invention may support handover between different networks which employ different radio access technologies and between small cells and macrocells.
