Method, apparatus and system for network flow control

Abstract

The invention discloses a method for controlling network flow, a device and a system thereof and pertains to the technical field of communication. The method comprises: the performance information sent by more than two network elements is received; according to the performance information, the chains to which abnormity happens in network or the network elements to which abnormity happens are confirmed; when the abnormal chains are confirmed, a first notice that the call volume on the abnormal chains is reduced is sent; when the abnormal network elements are confirmed, a second notice that thecall volume, the objective address of which is the abnormal network elements, is reduced is sent, or a third notice that the call volume which passes by the abnormal network elements is reduced is sent, thus causing the equipment which receives the notices to reduce the corresponding call volume. The device comprises a receiving module and a control module. The system comprises control equipment and at least two sending equipment. The method, the device and the system of the invention improve the accuracy of network flow control and lower the probability of over loading and even breakdown of the network elements.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device and system for network flow control. Background technique [0002] In the current telecommunications network, the service flow and load distribution of the entire network mainly adopt manual planning. When the business model is inconsistent with expectations, or failures and disasters occur, some nodes in the network will not work normally, and the efficiency of the entire network will be greatly affected. For example, a VMSC (Visited Mobile Switching Centre) is connected to two TMSCs (Tandem Mobile Switching Centre), and the number of calls sent from this VMSC to the two TMSCs is 100. When When a link from a VMSC to a TMSC is interrupted, the VMSC will send all calls to another link that has not failed, causing the load of the TMSC connected to the link to increase to 200, and the load of the two TMSCs Seriously unbalanced. If the load of the TM...

Problems solved by technology

[0004] After analyzing the existing technology, the inventor found that: due to the overloaded network element rejecting the call, the user may continue to make repeated calls, which will cause the number of calls received by the VMSC connected to the overloaded network element to continue to increase, or even overloaded to collapse

In the detection technology, the flow control is only based on the service success rate between the source network element and the destination network element, which is relatively one-sided. If the reason for the low success rate is not due to the link between the source network element and the destination network element If it is caused, reducing the traffic from the source network element to the destination network element may not be able to achieve the effect of accurate traffic control
