摘要： An apparatus and method for creating a data path for a broadcasting service in a cellular network is provided. In a method for creating a data path to provide a broadcasting service in a cellular network, a broadcast server transmits a session start request message to an Access Service Network-GateWay (ASN_GW) before transmission of Multicast and Broadcast Service (MBS) data, to request a multicast connection setup. The ASN_GW establishes a multicast connection between the broadcast server and the ASN_GW on the basis of information of the session start request message. The ASN_GW transmits a session start response message to the broadcast server in response to the session start request message, after establishment of the multicast connection between the broadcast server and the ASN_GW. The ASN_GW 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. The base station establishes a multicast connection between the ASN_GW and the base station on the basis of information of the path registration request message. The base station transmits a path registration response message to the ASN_GW in response to the path registration request message, after establishment of the multicast connection between the ASN_GW and the base station.
