The invention discloses a network virtualization method applicable to an enterprise grade broadband mobile communication system, and particularly relates to a resource segment channel network virtualization realization method integrating the traditional channel and the newly-developing network resource segment technology. The invention is applicable to supporting a network architecture of an OpenFlow protocol, realizes the support for the common channel technology by an Openflow interchanger by defining an OpenFlow (version.3) extension packet, improves the particle management and interchanging capacity on massive various service level data flows by upgrading the virtualization method which is based on the resource segment management proxy, wherein the virtualization method is distributed type and is based on the FlowVisor centralized type resource segment manager. As a result, the network virtualization method applicable to the enterprise grade broadband mobile communication system provides a network basic architecture which has high compatibility and expansibility and guarantees the network bandwidth, time delay and packet loss to various broadband mobile communication services to the enterprise data center.
