Title: The Method of Overload Control for Cell Broadcast Service
Inventor: SHIN JAE UK
IPC: H04B7/24
Filed: 2001-11-22
Abstract: PURPOSE: An overload control method for a cell broadcast service in a mobile communication system is provided to effectively control an overload during a cell broadcast service by controlling a radio resource and a broadcast period. CONSTITUTION: A BMC(Broadcast and Multicast Control) layer of a control station recognizes overload occurrence possibility(40) due to shortage of a radio resource, it requests the additional allocation of a radio resource from an RRC(Radio Resource Control) layer(41). If the RRC layer authenticates allocation of an additional radio resource, it allocates an additional radio resource for a cell broadcast service(42). If the control station receives a new broadcast from a cell broadcast center(45), it checks an overload state flag. If the overload state is 'true', the control station controls the overload by increasing a broadcast period by messages according to priority on the basis of a broadcast term, a broadcast period and the size of a broadcast message on the air by stages(47). If a broadcast for a specific broadcast message is completed in an overload state(48), the control station checks the overload state flag. If the overload state is 'true'(49), the control station restores to the original state by decreasing the broadcast period according to the priority on the basis of the broadcast term, the broadcast period and the size of the broadcast message on the air by stages(50). When the broadcast period for every broadcast message on the air is restored(51), the overload state flag is set to 'false' to transit to an overload release state(52), and the cell broadcast center is informed the release of the overload state(53).
