Abstract: A system and method for updating train control data are provided. The system for updating train control data can operate to revise, update and maintain the corresponding train control functions installed in an on-board device without workers directly approaching on-board and ground devices using a broadband wireless access system. The on-board device is configured to receive train control data classified by identification information via a wireless network and determine whether the train control data is train control data to be updated using the identification information. The on-board device is configured to update the train control data depending on whether the train control data is the train control data to be updated.

Abstract: An intelligent multiple access communication (MAC) control apparatus and method are disclosed. The intelligent MAC control apparatus includes a connection control unit, a resource management unit, a session control unit, a flow control unit, and a determination unit. The connection control unit connects at least one Radio Access Technology (RAT) and a wireless network. The resource management unit collects RAT information including information about available resources and radio state of the RAT. The session control unit checks the QoS of at least one connection target service. The flow control unit determines the priority of the connection target service, and selects a preferential connection target service. The determination unit determines a connection RAT for performing the preferential connection target service based on the QoS and the RAT information.
