Description
The present invention relates to a mobile communication system, and more particularly, to a method of controlling an overload of a service end device for performing work processing for providing a mobile communication service, and a switching end device and a mobile communication system therefor.
With the rapid development of computer, electronic and communication technologies, various wireless communication services using wireless networks have been provided. In order to provide such a service, a mobile communication system has been developed through a first generation analog AMPS (Advanced Mobile Phone Systems) method and a second generation cellular (PCS) / personal communication service (PCS) method. Recently, IMT-2000 (International Mobile Telecommunication-2000), a third generation high speed data communication, has been used. IMT-2000 was developed for personal mobility guarantee and high speed data transmission to ensure mobility between countries by integrating systems of countries using different wireless access standards. It is asynchronous with Code Division Multiple Access (CDMA) 2000, which is a synchronous method. It was developed separately from Wideband Code Division Multiple Access (WCDMA).
With the development of mobile communication technology, users are using not only mobile calls but also various types of mobile communication services such as short messages and mobile internet. As the usage rate of the mobile communication service increases, the call in the mobile communication system may be congested at a specific time. Therefore, the development of technology for the maintenance and management of a mobile communication system as well as the development of a mobile communication service is required.
An object of the present invention is to control overload in a mobile communication system.
The objects of the present invention are not limited to the above-mentioned objects, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.
In order to achieve the above object, in the overload control method according to an embodiment of the present invention, the overload control of the address of the service-end device in which the overload occurs among a plurality of service-end devices performing a task processing for providing a mobile communication service to the mobile terminal Setting an address, and blocking transmission of at least one of a plurality of control signals destined for the address set as the overload control address.
In order to achieve the above object, the switching end device according to an embodiment of the present invention overload control of the address of the service end device that the overload occurs among a plurality of service end devices performing a task processing for providing a mobile communication service to the mobile terminal And a storage unit for setting an address, and a controller for blocking transmission of at least one of a plurality of control signals destined for the address set as the overload control address.
In order to achieve the above object, a mobile communication system according to an embodiment of the present invention, the switching terminal device for exchanging a call of the mobile terminal, the operation for providing a mobile communication service to the mobile terminal at the request of the switching terminal device; A plurality of service end devices for performing processing, and a signaling gateway for relaying signals between the switching end device and the plurality of service end devices, wherein the switching end device comprises a service end having an overload among the plurality of service end devices; Set the address of the device as the overload control address, and block transmission of at least one of the plurality of control signals destined for the address set as the overload control address.
Specific details of other embodiments are included in the detailed description and the drawings.
According to the overload control method of the present invention as described above, the switching end device and the mobile communication system for this, it is possible to more effectively control the overload in the mobile communication system.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
