Data transfer method and control frame as well as one-to-many common media type communication system, base station apparatus, remote station

摘要

PROBLEM TO BE SOLVED: To provide a data transfer method by which a frame sent from a remote station device can be transferred to a base station device without colliding on a shared transmission path.;SOLUTION: The remote station device receiving an expansion transmission stoppage control frame A from the base station device reads the frame when the address of a DA field A1 is equal to the address of its own device. Then the remote station device recognizes that the frame is the expansion transmission stoppage control frame by a Type field A3 and a Code field A4, and stops transmission of the frame to the base station device in a period described in a Pause-time field A5. The base station device transmits the expansion transmission stoppage control frame A having a sufficiently large stopping time described in the Pause-time field A5 to all the remoter station device, and then the base station device transmits the expansion transmission stoppage control frame A having a sufficiently short stopping time described in the Pause-time field A5 to a specific remoter station device.;COPYRIGHT: (C)2003,JPO
