COMMUNICATIONS SYSTEM, COMMUNICATIONS CONTROL APPARATUS AND METHOD, AND COMPUTER PROGRAM THEREFOR |
摘要 |
A communications system sets a network frame period that can be repeatedly used by a plurality of wireless networks in a predetermined time period. A plurality of channel slots for use by each of the wireless networks is prepared in advance in the network frame. A coordinator operating a PAN activates its PAN in an area of a channel slot that is not used by the other coordinator(s). Since each of the wireless networks detects an unused channel slot in the network frame and uses the unused channel slot, the association process is greatly simplified.
