Embodiment Construction

[0027] An apparatus and method for controlling traffic between a wireless LAN terminal and an access point in a wireless local area network (LAN) system according to a first embodiment of the present invention are described in detail below with reference to the accompanying drawings.

[0028] figure 1 It is a functional block diagram of a wireless LAN system in a network connection state. refer to figure 1 , the wireless LAN system includes a wireless LAN terminal 100 (serving as an information terminal for a user to access a wireless LAN), an access point 200, a router 300, a hub 400, and an authentication server 500 providing Internet services. The access point 200 is located between the wireless LAN terminal 100 and the hub 400 to transmit an Internet access request from the wireless LAN terminal 100 to the authentication server 500 to relay the wireless LAN communication of the wireless LAN terminal 100 . The router 300 and the hub 400 allow the wireless LAN terminal 100...

Abstract

In an apparatus and method for controlling traffic of a real-time service between a wireless LAN terminal and an access point in a wireless local area network (LAN) system, the transceiver transmits / receives packets to / from the access point, and the signal determination unit determines the Whether the packet transmitted / received by the machine is a real-time packet, and the signal control unit controls retransmission according to transmission failure when the signal determination unit determines that the packet to be transmitted is a real-time packet. In this way, the present invention maintains an optimal traffic state in a wireless LAN environment, and reduces the risk of resetting an access point or a wireless LAN terminal. In addition, the present invention prevents real-time traffic of multiple coexisting wireless LANs from interfering with each other, and prevents voice and image data from being delayed or damaged.

Description

technical field [0001] The present invention relates to an apparatus and method for controlling traffic between a wireless LAN terminal and an access point in a wireless local area network (LAN) system. More particularly, the present invention relates to an apparatus and method suitable for excluding unnecessary retransmission of real-time traffic, thereby improving efficiency and quality of service (QoS) between terminals and preventing network failure. Background technique [0002] Generally, information terminals such as personal computers (PCs), notebook computers, and personal digital assistants (PDAs) share information through a so-called local area network (LAN). LANs can be classified into wired LANs that directly connect information terminals through communication cables or wireless LANs that connect information terminals using access points based on wireless communication technology. Such a wireless LAN can move freely, and is easy to expand and maintain because i...
