PROBLEM TO BE SOLVED: To provide an apparatus and method for creating a data path for a broadcasting service in a cellular network. SOLUTION: A broadcast server transmits a session start request message to a control station before transmission of Multicast and Broadcast Service (MBS) data, to request a multicast connection setup (201). The control station establishes a multicast connection between the broadcast server and the control station on the basis of information of the session start request message (203), transmits a response message to the broadcast server in response to the session start request message, and transmits a path registration request message to at least one base station associated with a broadcast zone, to request MBS data path establishment and air resource reservation (205). At least one base station establishes a multicast connection between the control station and the base station on the basis of information of the path registration request message (207), and transmits a path registration response message to the control station in response to the path registration request message (209).
