    摘要： A radio link switching scheme in which a communication between the base station and the mobile station is carried out through the radio link given in terms of frames while providing a switching timing information formed by a layer 1 bit data in each frame of the radio link such as a unique word, a flag, a housekeeping bit, and a frame number. Then, the switching timing information in at least one of the frames of the radio link at the base station is changed to indicate a switching of the radio link whenever a need for switching the radio link between the base station and the mobile station arises, and transmitted to the mobile station. At the base station, the radio link is switched at a switching timing which is a prescribed period of time after each frame in which the switching timing information is changed, while at the mobile station the radio link is switched at a switching timing which is a predetermined period of time after each frame in which the changed switching timing information is detected.

    摘要： Upon executing data exchange between a pair of LAN's(3, 5) via a gate way(11), a root hub(RH1-RH6) transmits the communication data, in an address describing area of which source/destination addresses are described, and a gate way(11) decodes the source/destination addresses included in received communication data, decides whether or not the source and the destination belong to the same LAN based on decoded source/destination addresses and attribution identification information, selects an appropriate route as the destination of the communication data based on a result of this attribution decision, and then transmits the communication data to the destination via selected route.

    摘要： In a system where transmission right communication device 1-2 in plural communication devices 1-1 through 1-16 connected with a bus 3 transmits data to transmission requesting communication devices 1-1 and 1-3 through 1-16, the transmission right communication device transmits a collecting command, and when a transmission request is made, the respective transmission requesting communication devices add their self addresses to the collecting command so as to transmit the collecting command, and the transmission right communication device receives the collecting command to which the self addresses of all the transmission requesting communication devices making the transmission request are collectively added.
