Abstract
The present invention provides a method for updating a mobile terminal (MT) for a mobile communication network when the MT crosses a boundary of a first location-update (LA) area. The method comprises determining a second LA to be assigned to the MT for replacing the first LA. The second LA is characterized by a LA center and a LA size, both determined by optimizing them in a sense that a mean total location-management cost is minimized without restricting the LA center to be fixed at the initial position. The initial position is defined as the location where the MT performs a latest location update at the first LA before crossing the boundary. This invention also provides schemes of partitioning the second LA into sub-paging areas for use in paging the MT when a call arrives at the network, so as to minimize the paging cost while satisfying delay requirements.
