Virtualized wireless communication system and establishing method thereof

摘要

The present application discloses a virtualized wireless communication network and an establishing method thereof. The virtualized wireless communication network system includes a plurality of virtual nodes, the plurality of virtual nodes being divided into multiple virtual node cliques according to interference relations among the plurality of virtual nodes, wherein, each virtual node represents a wireless communication node; and a plurality of clique communication management modules that are one-to-one associated with the multiple virtual node cliques, wherein, each clique communication management module is configured to manage data exchange between an associated virtual node clique and other virtual node cliques, so as to emulate communication behavior of the wireless communication node. The present invention has many advantages such as high flexibility, good scalability, low cost and the like. Compared with a centralized virtualization solution, this solution can significantly reduce management data overhead and thus enhance the real-time behavior of the whole system.
