METHOD AND APPARATUS FOR MANAGING MOBILITY BETWEEN HETEROGENEOUS NETWORKS

A method and an apparatus for managing mobility of a terminal between heterogeneous networks. The method includes: generating applications each corresponding to a plurality of terminals and data units (DUs) of a plurality of heterogeneous networks using software defined network (SDN) technology; collecting radio channel measurement data on channels of radio networks from the plurality of terminals through terminal applications corresponding to the plurality of terminals; collecting an average value of radio resources used in radio units (RUs) of the plurality of heterogeneous networks and network congestion data of the RUs of the plurality of heterogeneous networks through DU applications corresponding to the DUs of the plurality of heterogeneous networks; and determining whether or not to change networks of the plurality of terminals on the basis of the radio channel measurement data, the average value of the radio resources, and the network congestion data.
