Abstract: PROBLEM TO BE SOLVED: To enable execution of mediation of access competition in a relatively short time, even if the number of communication devices or data streams is increased, to avoid collisions among communication devices that have the same priority level in preferential control, and to execute appropriate access control, according to the traffic conditions, such as, communication volume to prevent performance degradation. SOLUTION: Mediation of an access right by a priority group is combined with slot mediation, the mediation of the priority group is executed in PGA times (PGA0, PGA1) after transmission of a frame P0 is completed, and an accessible priority group is narrowed down. A priority group having obtained an access right executes mediation by a slot number in the next slot mediation zone, and, for instance, a communication device with a slot number 2 allocated thereto transmits a frame P1 at a slot of No. 2. Here, the priority group is changed according to the traffic condition, and slot allocation information is updated by priority groups. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a communication method which can prevent the occurrence of collision to prevent the deterioration in performance even when the number of connected communication apparatuses increases and which can define the maximum delay of transmission to set the priority. SOLUTION: When transmitting data to a PLC modem 100Ty, a PLC model 100Tx starts transmission in common timing in which all the PLC modems can perform transmission (S11). An ID number of a common ID is added to a data frame at such a time, and this ID number is detected by a master PLC modem 100M. The master PLC modem 100M assigns an individual ID to the PLC modem 100Tx and notifies it by a control frame (S30). The PLC modem 100Tx sets the notified individual ID and performs subsequent data frame transmission in timing corresponding to the notified individual ID (S41). COPYRIGHT: (C)2009,JPO&INPIT

When it is determines that the own device is present in the proximity radio communication area 30, the slave device 20 notifies the master device 10 and establishes connection between the master device 10 and the slave device 20 by using the proximity radio communication.
