Problems solved by technology

[0010] However, with the increasing development of multimedia communication, the congestion situation of each office in the multimedia communication system will become increasingly serious, but currently the H323 protocol under the softswitch system cannot Automatically control the congestion of each office, so that when traffic congestion occurs between adjacent offices, the congestion cannot be controlled through various internal settings and adjustments of the system

Embodiment Construction

[0028] First, the technical terms involved in the present invention are explained as follows:

[0029] Automatic congestion control service: refers to the automatic flow control service initiated by the congested exchange and completed by the adjacent exchange when the traffic to a certain office direction is too large and the traffic load is too large. .

[0032]

[0033] In the present invention, the definition of the automatic congestion level parameter field above can be used, for example, 00000000~01100100 in this parameter is defined to indicate 0% to 100%, 00000000 (0%) indicates that no call barring is required for the congested station, 01100100 (100%) ) indicates that all calls to the congested office need to be restricted. In order to be compatible with current equipment, the definitions of 00000001 and 00000010 ca...

Abstract

The method comprises: a) the congested exchange receives an initiation address message or a call-establishing request message from the congestion-controlling exchange; b) the congested exchange sends a message carrying automatic congestion parameters to the congestion-controlled exchange; c) the congestion-controlling exchange receives the message carrying the automatic congestion parameters, and in term of the parameters sets the ratio for limiting the call, and then in term of the ratio for limiting the call, limits the call for the congested exchange.

Description

technical field [0001] The invention relates to a method for realizing automatic congestion control between exchanges in the field of communication, and more particularly, to a method for realizing automatic congestion control in H323 under ISUP protocol, BICC protocol and softswitch system. Background technique [0002] ISDN User Part (ISUP), a major protocol of the SS7 / C7 signaling system, defines protocols and procedures for establishing, managing, and releasing trunk circuits in the Public Switched Telephone Network (PSTN) to transmit voice and data calls. ISUP applies to ISDN calls and non-ISDN calls. [0003] Now, many international standards organizations are working on the next generation network (NGN) standards. As an asymmetric protocol in the NGN protocol, the bearer independent call control protocol (BICC protocol) is evolved from the ISUP protocol and standardized by the ITU-TSG11 group, which provides support independent of bearer technology and signaling tra...
