METHOD OF ALLOCATING DYNAMIC RADIO RESOURCES FOR LTE BACKHAUL SYSTEM

According to the present invention, the dynamic resource allocation method for a wireless backhaul system is performed in the wireless backhaul system including a backhaul relay terminal wirelessly connected to a basic base station serving as a macro base station connected to a mobile communication core network, and wire-connected to a mobile communication base station or a WiFi AP serving as a backhaul base station to transmit data of a user terminal between the basic base station and the backhaul base station, and a backhaul controller for controlling the backhaul relay terminal between the core network and the basic base station. The method of the present invention includes the steps of: (a) receiving, by the backhaul controller, an initial terminal message from the backhaul relay terminal in a radio resource control (RRC) connection setup process to transmit the initial terminal message to the core network; (b) relaying, by the backhaul controller, an authentication procedure for the backhaul relay terminal between the core network and the basic base station; (c) relaying a radio bearer setup procedure for the backhaul relay terminal between the core network and the basic base station, by the backhaul controller; (d) relaying an access procedure for the backhaul relay terminal between the core network and the basic base station, by the backhaul controller; and (e) performing, by the backhaul controller, a procedure of additionally setting a bearer for guaranteeing fixed data transmission to the backhaul relay terminal according to a dynamic resource allocation algorithm of the backhaul controller established by dynamically reflecting a service state of the backhaul relay terminal between the basic base station and the backhaul controller.
