Abstract: A wireless communication system includes switching infrastructure (150) and at least one location area ("LA") having a multiplicity of cells (the "multiple-cell LA") (103). When a mobile (100) enters a cell belonging to the multiple-cell LA, the mobile is arranged with a cell-registration feature that enables it to register with the serving cell site, thus forming a registration with the cell site. When the mobile enters a further cell belonging to the multiple-cell LA, the mobile registers with the corresponding further cell site, thus forming a registration with the further cell site. When the switching infrastructure receives a call attempt towards the mobile, the switching infrastructure pages the mobile in only those cells in which a cell registration exists for the mobile.
