Method for realizing traffic control

Abstract

The invention discloses a method for realizing traffic control, which comprises the following steps: when detecting that the calling off-hook event occurs for a user, a media gateway MG reports the calling off-hook event for the user to a media gateway controller MGC; and after knowing the calling off-hook event for the user, the MGC judges whether the traffic control is needed or not, if necessary, the MGC obtains traffic control levels and controls traffic according the traffic control levels. After the call enters the MGC, the invention judges whether the traffic is controlled or not, and realizes the controllability of the CPU of the MGC in first time, thereby preventing the CPU of the MGC from exceeding the limit to lead to the crash fault of the MGC due to the burst increase of the user access number, and efficiently and rapidly realizing the traffic control of the MGC without further increasing the load of the CPU.

Description

technical field [0001] The invention relates to the next generation network, in particular to a method for realizing traffic control in the next generation network. Background technique [0002] The next generation network (Next Generation Network, NGN) takes the soft switch as the core, such as figure 1 As shown, NGN includes MG (media gateway) and MGC (media gateway controller, i.e. soft switch), and MG is responsible for media transformation and establishing connection between PSTN (public switched telephone network) and IP network; MGC is responsible for , to control the establishment and release of MG connections, mainly including: protocol access layer (L2 / L3), service layer (L4) and service management layer (L5), etc. MGC is also connected to network elements such as TG (trunk gateway). [0003] MGC adopts the same mechanism as IP and ATM (Asynchronous Transfer Mode) transmission network. On the one hand, it realizes the interaction of voice, image and data; on the o...

However, these methods all have the defect of untimely processing, and the data area restriction method must wait until the subsystem of each call applies for a data area before judging whether traffic control is needed; refer to figure 1 , the upper-layer service control method requires the call to be accessed by the protocol access layer (L2 / L3), and transferred from the protocol access layer to the service layer (L4), and then the service layer evaluates whether traffic control is needed according to a certain method; the above method Both will lead to the inability to control the traffic in time, and in the above methods, the CPU of the MGC needs to complete a certain operation before it can judge whether to control the traffic, which will not only further increase the load on the CPU, but also cannot realize the traffic in the first time. business control
