METHOD FOR PROVIDING A MULTIMEDIA SERVICE IN A WIRELESS LAN SYSTEM, ESPECIALLY CONCERNED WITH GIVING PRIORITY TO A REAL-TIME SERVICE IN A WIRELESS LAN AND PROVIDING QOS

摘要

PURPOSE: A method for providing a multimedia service in a wireless LAN(Local Area Network) system is provided to increase the throughput of data and decrease delay time by granting transmission priority to multimedia data in a wireless LAN system. CONSTITUTION: In case that a wireless terminal connected to a wireless LAN system attempts data transmission, but attempts the retransmission of the data due to a collision, the wireless LAN system judges whether the data that the wireless terminal wants to retransmit are multimedia data. If the retransmission data are multimedia data, the wireless LAN system multiplies the first backoff time by a specific number and sets the second backoff time. The wireless terminal transmits the multimedia data after the second backoff time.
