Abstract
An overload control method of a high speed data communication system can include judging whether an access network is overloaded, determining a class of the overload and restricting an originating call and a termination call according to the determined class during the overload. Since the access terminal, which can be the lowermost terminal of the system, controls the data call origination, resources at the side of the access network can be effectively managed. In addition, the overload control can be discriminately performed according to a degree of the overload so that the overload control method can effectively cope with the overload situation.
Claims19
An overload control method of a data communication system comprising:
- judging whether an access network is overloaded;
- and
- determining a class of the overload and restricting an originating call and a termination call according to the determined class, when the access network is overloaded.
An overload control method of a high speed data communication system comprising:
- checking a load state of an access network;
- determining a class of overload when the access network is overloaded and determining a call acceptance rate according to the determined class;
- and
- restricting an originating call and a termination call in accordance with the call acceptance rate.
A data communication system, comprising:
- an access network that includes a processor configured to repeatedly determine a variable load status of the access network, and wherein the processor determines a class of overload when the access network is overloaded;
- an access terminal coupled to the access network configured to restrict originating calls in accordance with the overload class, wherein a call acceptance rate is judged from the overload class that restricts both originating and termination calls when the determined class is below a base-level and restricts the originating calls when the determined class is not below the base-level;
- a packet control unit coupled to the access network configured to provide packet service to the access terminal;
- and
- an authentication server coupled to the packet control unit configured to provide authentication functions to the packet control unit.
