Abstract
A system and method of restricting an on-going call of a fixed subscriber to a fixed subscription area (FSA) in a cellular telecommunication system having a plurality of cells and a plurality of subscribers. The plurality of subscribers includes at least one fixed subscriber assigned to the FSA and engaged in an on-going call in a serving cell.
