To make the configuration of media gateway more flexible,enhance its network capacity and reliability,a design and im-plementation method about the media gateway is proposed.Considering how to configure and manage all kinds of business cards flexibly,and how to complete the internal signaling/protocol switching.A rack structure is proposed in hardware.While the backboard bus is used for communicating between all business cards and key card.The softswitch architecture is adopted in software.In order to realize the separation between call and bearer,business and control,the abstract signalling design idea is proposed.The system can be used as relay media gateway,media gateway access,to meet the high capacity and high reliability requirements.
