    • A method for performing a protocol interfacing operation for a plurality of nodes in an IEEE1394 serial bus network. Upon initialization of an IEEE1394 serial bus due to node addition or deletion, each of the nodes formats a protocol identifier packet and sends it to the other nodes. A bus manager stores the protocol identifier packets of the nodes into a protocol map. Then, a source node sends a protocol query packet including a target node identifier to the bus manager to request the transfer of data. Upon receiving the protocol query packet from the source node, the bus manager retrieves a communication protocol from the protocol map and sends a protocol set packet including information about the retrieved communication protocol to the source node and a target node to perform the transfer of data between the source and target nodes through the communication protocol. Therefore, the data transfer can efficiently be performed with no necessity for checking protocols one by one.
    • 一种用于对IEEE1394串行总线网络中的多个节点执行协议接口操作的方法。 由于节点添加或删除,在IEEE1394串行总线初始化时,每个节点格式化协议标识符分组,并将其发送到其他节点。 总线管理器将节点的协议标识分组存储到协议映射中。 然后,源节点向总线管理器发送包括目标节点标识符的协议查询分组,以请求传输数据。 在从源节点接收到协议查询分组时,总线管理器从协议映射中检索通信协议,并将包括关于检索到的通信协议的信息的协议集分组发送到源节点和目标节点,以执行数据之间的传输 源节点和目标节点通过通信协议。 因此,可以有效地执行数据传送,而不必一一检查协议。

    • Disclosed is an apparatus for switching MIMO modes, which can efficiently switch an MIMO mode of a mobile station. The apparatus for switching MIMO modes includes an MIMO mode determining unit, a staying time determining unit, and an MIMO mode switching unit. The MIMO mode determining unit determines a current MIMO mode of a mobile station. The staying time determining unit determines a first staying time in a first MIMO mode of the mobile station when the MIMO mode determining unit determines the current MIMO mode of the mobile station as the first MIMO mode for transmitting the same data through a plurality of antennas, and determines a second staying time in a second MIMO mode of the mobile station when the MIMO mode determining unit determines the current MIMO mode of the mobile station as the second MIMO mode for transmitting different data by antenna. The MIMO mode switching unit switches the MIMO mode of the mobile station to the second MIMO mode when the first staying time is greater than or equal to a first threshold staying time.
