Abstract:
1. A method of controlling the transmission and reception of a frame in a LAN system comprising the steps of: adding timing information as to a timing of transmitting a next frame from each terminal to a current frame when said current frame is transmitted from said each terminal onto a shared transmission line; providing a timing reservation management table and a timer which measures time at certain interval of time and outputs as an address of said table in each terminal; extracting said timing information from said current frame which is transmitted onto said shared transmission line from another terminal; reserving both the timing (A) of receiving said next frame from said other terminal and the timing (B) of transmitting a next frame from its own terminal by recording ‘frame transmission by other terminal’ and ‘frame transmission by its own terminal’ respectively in addresses of said timing reservation management table, a number of addresses being determined based upon said timing (A) and timing (B); and transmitting the next frame onto said shared transmission line when said timing (B) of transmitting said next frame from its own comes by reference to said timing reservation management table.
