A localised billing plan for a mobile wireless communication unit (107) in a cellular communication system can be preserved when the unit relocates from one cell to another by including billing Service Area Identity (SAI) of the source cell in the handover message to the target cell. The billing service area identity may be included in a last visited cell list. Aspects of the invention include a method for maintaining a billing plan or tariff in a cellular communication system, a network element, an integrated circuit adapted to configure a message for transmission and a tangible computer program product. The handover may be from one macro-cell to another macro cell, from one femto-cell to another femto-cell and between macro-cells and femto-cells, or between different radio access networks. In an aspect of the invention, signal processing logic attaches cell As SAI, tagged with its billing information, as an IE (Information element) or UE history information which is associated with the most recently visited cell in the UE history information. The access point then transmits this modified UE history information to the target cell C, which is received in node B Access point and passed for decoding. |
