An access control method applicable to a network including a plurality of communication terminals for achieving simplification in processing, improvement in response, and efficient use of bands is provided. In a terminal station 21 , a transmission information generating section 213 generates predetermined transmission information based on the amount of data stored in a buffer section 212 . A packet transmitting section 214 generates a packet including data and the transmission information for transmission to another terminal station 22 . In a control station 11 , a packet receiving section 111 receives the packet transmitted by the terminal station 21 . A transmission information obtaining section 112 analyzes the received packet to obtain the transmission information and, based on the transmission information, determines whether the band currently allocated is to be changed. If a changed is required, a packet transmitting section 114 transmits a packet reporting a newly-allocated band to the terminal stations 21, 22.
