A SIGNALING AGENT REALIZING METHOD BASED ON MEDIA GATEWAY CONTROL PROTOCOL

摘要

The present invention discloses a signaling agent realizing method based on media gateway control protocol, comprising the following steps: setting the agent devices between media gateways and media gateway controllers located in different networks, said agent device provides signaling agent and network address conversion functions among different networks; media gateways register to media gateway controllers; to those MGCP/MEGACO signaling independent to media between media gateway controllers and media gateways, the agent device replaces transaction numbers directly and then transmits it; to those MGCP/MEGACO signaling correlated with media, the agent device processes the media attributes and then transmits it. The present invention can realize a transparent through of MGCP protocols in different networks, thus the media gateway controller can control the media gateway taking no account of network location of the media gateway, the information of the media gateway is created dynamically by the agent device according to MGCP signaling, and therefore the management maintenance cost is reduced.
