MME, Local Server, MME-Local Server interface and Data Transmission Method for Optimized Data Path in LTE Network

The present invention relates to the MME with a local server, an interface between them and a data transmission and reception method for optimum data path in the LTE network. In accordance with the present invention, a communication method of the MME (mobility management entity) to support handover between the gateway by the terminal, if the handover is detected as a target gateway of the data transmission of the UE from the source gateway, between the terminal and the server, If the session information for the local server to which the phase and the session information for obtaining the session information exists in the mobile communication core network, comprising the steps of: via the interface and the local server sends a tunnel configuration command to said local server, said tunnel establishment command relates the local server to the the data transfer to the target gateway, a communication method and apparatus characterized in that it comprises a command for setting the target tunnel between the gateway and the local server.
