Embodiment Construction

[0037] The core idea of the present invention is to provide an overload control method and device in a media gateway. The TMG determines the proportion of allowed calls according to the current processing capacity, which ensures that the call restriction and access of the TMG can be dynamically adjusted, and improves the TMG. Call completion rate and operational stability.

[0038] The present invention provides an overload control device in a media gateway, and the device can be applied in TMG or AMG (Access Media Gateway). In this embodiment, the device is set in TMG as an example, as shown in FIG. 3 , the device is used for overload control according to the current processing capacity of the TMG. The device includes a call pass rate calculation module, which is used to periodically calculate the ratio of the allowed call of the current TMG, which includes a CPU occupancy rate calculation submodule, which is used to calculate the current CPU occupancy rate; the call connec...

Abstract

The related overloading control method for media gateway comprises: a calling pass-rate calculation module in the gateway calculates the allowable calling ratio according to current process capacity, a calling pass-rate adjust module accordingly adjusts the pass-rate for next time and controls the gateway loading. This invention dynamic adjusts the calling pass-rate to improve the calling pass rate and the system stability.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an overload control method and device in a media gateway. Background technique [0002] Overload control is based on system capacity and performance analysis. In order to ensure the stable operation of the system, the correct overload control algorithm must be adopted. When the system capacity reaches a saturated state, the acceptance of new calls is restricted to ensure the stable connection of existing calls; calls to improve call completion rate. During the overload control process of the system, the limit and increase of calls are dynamically changed and automatically adjusted according to the operating state of the system. [0003] In the NGN (Next Generation Network) networking mode shown in Figure 1, the lower-level switch directly connects to the user, and the TMG (trunk media gateway) is responsible for the establishment of the bearer. When the TMG receives the ...
