Abstract: PURPOSE: A terminal connection control method in a HIPERLAN type 2 is provided to effectively use limited resources by controlling connection of numerous terminals when they simultaneously transmit data in TDMA(Time Division Multiple Access)/TDD(Time Division Duplexing). CONSTITUTION: A new MAC frame starts(S410). A transmission probability value is calculated by using a traffic volume and the number of RCHs(Random Access Channel) of a previous frame(S411). The transmission probability value is controlled by comparing a minimum value, a maximum value of a probability value range and the transmission probability value(S412). The number of RCHs and the set transmission probability value are transmitted to each terminal(S413). A random number is generated between 0 and 1 in each terminal(S414). The random number is compared with the set transmission probability value(S415). If the random number is smaller than the set transmission probability value, one RCH is selected(S416) and connection to an AP is attempted(S417). The AP successfully receives connection of each terminal, and each signal receives a positive feedback(S418). The AP allocates an uplink resource to each terminal(S419). Each terminal transmits data to uplink through the selected RCH(S420).
