Broadcasting method, access control apparatus, and terminal apparatus

摘要

A processing unit generates the timing information on the timing with which each of radio apparatuses is to synchronize in communications between the radio apparatuses when each of radio apparatuses broadcasts a signal. A modem unit, an RF unit and an antenna broadcast the generated timing information. The processing unit further generates the cycle information on a broadcast cycle in which each radio apparatus broadcasts the signal in communication between the radio apparatuses. The modem unit, the RF unit and the antenna broadcast the cycle information together with the timing information.

1. An access control apparatus comprising:
a controller configured to control communication between terminal apparatuses without having any direct involvement in data communication between the terminal apparatuses and without directly specifying a slot to be used in the data communication; a generator configured to generate timing information on timing of a frame with which each of the terminal apparatuses is to synchronize in communication between the terminal apparatuses when each of the terminal apparatuses broadcasts a signal, the frame being followed by other frames; and a broadcasting unit configured to broadcast a packet including the timing information generated by said generator, wherein said generator further generates cycle information on a broadcast cycle, the broadcast cycle being an interval between broadcasts of signals by each of the terminal apparatuses, in communication between the terminal apparatuses, said broadcasting unit broadcasts the cycle information generated by said generator, together with the timing information, the access control apparatus further comprises a decision unit configured to increase the broadcast cycle by an integral multiple of the broadcast cycle or decrease the broadcast cycle by a reciprocal of an integral multiple thereof, and output a determined broadcast cycle to the generator, and the cycle information is included in the packet together with the timing information.
