摘要
A method for processing packets in a polling-based WLAN system comprises: scheduling a superframe to include a first period in which only a terminal receiving a polling message from an access point (AP) is allowed to access a medium without contention, the AP transmitting the polling message to arbitrary terminals, and a second period in which a terminal is allowed to access the medium with contention; firstly transmitting, by means of the AP, during a first sub-period in the first period of the superframe, packets stored in a queue of the AP to the arbitrary terminals; and secondly transmitting, during a second sub-period of the first period, packets that are not transmitted in time during the first sub-period in the first period but are accumulated in the queue. Thus, it is possible to supplement packets that are received from an Ethernet, which is unable to guarantee QoS, through proper scheduling upon communication with another subnet and to recognize information about abnormally operating terminals, so as to guarantee overall QoS.
