sending, by a Media Gateway Controller (MGC), domain information of a first Internet Protocol (IP) domain network and domain information of a second IP domain network, wherein the domain information of the first IP domain network and the domain information of the second IP domain network is each carried in a LocalControl Descriptor contained in a message from the MGC; receiving, by an interconnecting Media Gateway (MG) positioned to connect the first IP domain network and the second IP domain network, domain information of the first IP domain network and domain information of the second IP domain network from the MGC; creating, by the MG, a first media stream between the interconnecting MG and a first MG located in the first IP domain network according to the domain information of the first IP domain network; creating, by the MG, a second media stream between the interconnecting MG and a second MG located in the second IP domain network according to the domain information of the second IP domain network; and connecting, by the MG, the first media stream and the second media stream to form a data communication path between the first MG and the second MG. |
