Abstract:
1. A communication method for a plurality of communication terminals sharing a single channel to permit a communication terminal to communicate at a predetermined communication cycle while avoiding a collision with an other communication terminal, comprising: a communication timing registering step for allocating communication timing of a communication terminal intending to start a communication within said communication cycle; upon start-up of the communication; and a notifying step for notifying other communication terminals sharing said channel of the allocated communication timing; whereby said notifying is performed for each iteration of said communication cycle; wherein a real time region for communicating real time data based on the allocated communication timing and a random access region for communicating data at random timing are provided by dividing said communication cycle into two sections; wherein if the real time data transmitted through said real time region is not received properly, said real time data not received properly is re-transmitted through said random access region.
