Abstract
A media gateway, which generates a context based on a control message transmitted from a media gateway controller and controls bearer transfers between a first network and a second network, comprises a context determination unit, an optimization judgment unit, an optimization processing unit, and a context control unit. The context determination unit determines an existence of an internal connection between a first context related to the first network and a second context related to the second network based on the respective control messages. The optimization judgment unit judges a possibility for generating a new third context by combining the first context and the second context, when the internal connection exists. The optimization processing unit generates the third context when it is possible to generate, and associates resource information of the third context with each of resource information of the first context and the second context. The context control unit controls the bearer transfer between the first network and the second network based on the third context, and performs communication with the media gateway controller using respective resource information of the first context and the second context.
