A method for performing system load control on mobile switch center

Abstract

This invention relates to a system load control method of mobile exchange center. The procedures are that a overloading control process that independent run in system is built to initialize data and enter working state when the system is started or transferring of reserve machine to main machine. A super timer is set to send timer message to overloading control process in supporting system. CPU occupancy is detected and the system overloading or overloading release is determined unitedly to make sure whether to use overloading control and judge whether to accept or limit certain business. Businesses that allow accessing is set in schedule time interval to limit the exceeding business when the overloading control is needed. System load control complexity is reduced by this method and it is convenient to unified management and maintenance. Load fluctuation in load control is reduced and load control failure is avoided by this invention.

Description

technical field [0001] The invention relates to a system load control method, in particular to a method for realizing overload control of MSC (Mobile Switching Center) in a CDMA (Code Division Multiple Access) communication system. Background technique [0002] In the CDMA mobile communication system, MSC is at the core position (such as figure 1 As shown), it interacts with other entities in real time through signaling, and forms the No. 7 signaling network together with other entities. MSC is a functional entity that controls and switches mobile stations (MS) located in its coverage area. Interfaces to other mobile switching networks. In addition to the functions such as call control performed by the switching center in the fixed network, the MSC also needs to complete functions such as wireless resource management and mobility management. In addition, in order to establish call routing to the mobile station, each MSC should also be able to complete the function of the ...

Problems solved by technology

Its disadvantages are: (1) The way to determine the traffic level is complicated, which will easily lead to the system out of control; (2) The setting of the timer lacks protection. When the setting of the timer fails, the system loses the ability to control the load; (3) Each module has a set of Own overload control method is not conducive to unified management and maintenance

Its disadvantages are: it has not fundamentally solved the drawbacks of the overload control mechanism being too complicated, and in the process of overload control, the number of messages processed by the system is allowed to fluctuate greatly, which is not conducive to the stability of the system, especially in the system flow control. When the level is the highest flow control level and the timer setting fails, all services will be rejected, resulting in a suspended state of the system
