Embodiment Construction

[0042] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] The method for receiving the accompanying signal in the present invention, such as image 3 shown, including the following steps:

[0044] Step S302, expanding the gateway protocol H.248 channel-associated signaling packet icasc (ID: Ox007d) addr event (ID: Ox0001) description parameter, which is defined as:

[0045] Name: Unpredictable Dn (signal bit of unpredictable category);

[0046] Parameter ID: updn(0x000c);

[0047] class: enum;

[0048] Possible values:

[0049] "updn01" (0x0001) corresponds to the value 1

[0050] "updn02" (0x0002) corresponds to the value 2

[0051] "updn03" (0x0003) corresponds to the value 3

[0052] "updn04" (0x0004) corresponds to the value 4

[0053] "updn05" (0x0005) corresponds to the value 5

[0054] "updn06" (0x0006) corresponds to the value 6

[0055] "updn07" (0x0007) correspon...

Abstract

The utility model relates to a method for receiving channel associated signal, comprising following steps: First, the address event description parameter of a gateway protocol H.248 channel associated signaling packet is extended, the address event description parameter is defined as the information address parameter which cannot be predicted; second, in the address requesting sequence sent to the media gateway in the media gateway controller, a multi-frequency mutual-controlled signal that cannot be determined currently is received with extended the address event description parameter; third, after the multi-frequency mutual-controlled signal that cannot be confirmed is received by the media gateway, the signal address parameter is reported to the media gateway controller; fourth, address informing information reported by the media gateway with unpredicted type signal address parameter is received by the media gateway controller, then the actual type of multi-frequency mutual-controlled signal which cannot be predicted is judged according to the received signal information and related configuration information in the media gateway controller.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to MGC (Media Gateway Controller, Media Gateway Controller) controlling MG (Media Gateway, Media Gateway) in a softswitch network to receive MFC (Multi-Frequency Mutual Control Register signal, Multi-Frequency Compelled Signaling) signal method. Background technique [0002] With the increasingly wide application of communication systems in various fields such as economy and social life, communication technology itself is also developing rapidly. Softswitch technology is a voice communication solution commonly used in fixed and mobile communication networks. The main softswitch technology The feature is the separation of bearer and control. The MGC realizes the control of the MG through the gateway control protocol (H.248) defined by the ITU-T (International Telecommunication Union Telecommunication Standardization Group), and completes the establishment and exchange o...
