Abstract:
1. A mobile radio communications device arranged for operation within a mobile radio communication network comprising a plurality of location areas each comprising a plurality of cells, the device including: a unit that identifies an approaching border region of an area with a neighboring area; a triggering unit that triggers location update signaling from the device to reflect a change in area responsive to the identification of the border; and a delaying unit that delays transmission of the location update signaling, wherein said delaying unit includes a random delay unit that determines autonomously a random delay as a delay of said delaying unit in said transmission of the location update signaling, and wherein, in the location update signaling, the mobile radio communication network provides information that allows the mobile radio communications device to identify cells that belong to the border by at least one of a cell identity for border cells, a bit mask to identify the border cells from the cell identity, a cell identity of a center cell, and a distance of the border cells to the center cell.
