A communication method in a wireless network system using both a contention mode communication period and a contention-free mode communication period determined by a polling operation of a control station as a communication protocol between communication stations controlled by the control station, said communication method comprising the steps of:

  • (a) providing time-slots in the contention-free mode communications period;

    (b) employing one of the communication stations to establish a call-connection between itself and another one of the communication stations through executing a procedure of call-connection with the control station in order to communicate in the time-slots; and

    (c) when the control station acknowledges that the call-connection is established, performing a packet communication operation involving transmitting packets between the one of the communication stations and the another one of the communication stations in the time-slots while bypassing the control station.
