A multi-network convergence method, comprising: acquiring network information of a plurality of vehicular networks and service information born by each vehicular network, wherein the service information at least comprises at least one service feature and service importance, the at least one service feature is used for representing at least one service type born by each vehicular network and the service importance is used for representing importance of at least one service born by each vehicular network; determining whether at least one service born by a first vehicular network coexists with at least one service born by the other vehicular networks or not according to the service information, wherein the first vehicular network is any one of the plurality of vehicular networks; and acquiring at least one vehicular network set with coexisting services according to a determination result, wherein the vehicular network set is a set comprising at least one vehicular network with the same service feature type; wherein acquiring the at least one vehicular network set with the coexisting services according to the determination result comprises: when at least one second vehicular network of which at least one service coexists with at least one service born by the first vehicular network exists, acquiring a vehicular network set comprising the first vehicular network and the at least one second vehicular network; and when the at least one second vehicular network of which the at least one service coexists with the at least one service born by the first vehicular network does not exist, determining (S 1063) the first vehicular network as an independent vehicular network set; characterized in that after acquiring the at least one vehicular network set with the coexisting services according to the determination result, the method further comprises: counting and determining a number n of the at least one vehicular network set, wherein n is a positive integer larger than 0; and dividing a network into n virtual sub-networks according to the at least one vehicular network set, wherein the virtual sub-networks are the same as the at least one vehicular network contained in a corresponding vehicular network set; wherein after dividing the network into the n virtual sub-networks according to the at least one vehicular network set, the method further comprises: when data transmission is performed by use of at least one vehicular network, performing the data transmission according to a priority sequence of each sequenced vehicular network set; or when data transmission is performed by use of each vehicular network contained in a vehicular network set, performing the data transmission according to a priority sequence of each sequenced vehicular network in this vehicular network set. acquiring network information of a plurality of vehicular networks and service information born by each vehicular network, wherein the service information at least comprises at least one service feature and service importance, the at least one service feature is used for representing at least one service type born by each vehicular network and the service importance is used for representing importance of at least one service born by each vehicular network;
