<p>A gateway control agent (GCA) is deployed between the media gateway controller (MGC) of a packet network and a plurality of media gateways (MG), a mapping relation is established between the MGC and the MGs; the MGC requests the GCA for some services uniformly, the GCA selects an appropriate resource capacity among the MGs managed by the GCA, and maps between a single media gateway domain and a media gateway class domain represented by the GCA. An implementation method of the GCA is also provided. By the present invention, the MGC treats a plurality of MGs as a resource class, without need to regard the detail of a MG, and layering control and simplified operation are achieved.</p> |
