Abstract
The present invention relates to a multi-media broadcast and multicast service (MBMS) providing system and a method thereof. The MBMS providing system provides an MBMS to a terminal having an MBMS function. The MBMS providing system includes a service center and a radio access network. The service center provides MBMS data and metadata having service announcement information abut the MBMS to the terminal. The radio access network periodically transmits establishment information for receiving the metadata to the terminal, and provides the metadata and the MBMS data received from the service center to the terminal through nodes for transmitting data. The establishment information includes first establishment information having a service identifier and IP/UDP parameters for receiving the metadata, and second establishment information for establishing a radio channel.
