Embodiment Construction

[0039] In the following, a wireless local area network (WLAN) will be used for illustration, but the content of the present invention is applicable to various wireless network systems, and is not limited to be used in a wireless local area network. In addition, although the embodiment will be explained based on the multicast instant messaging package, the technology can also be applied to non-instant messaging packages or other mechanisms with similar transmission behaviors to multicasting.

[0040] Please refer to FIG. 5 , which is a system architecture diagram of a wireless network applicable to the present invention. In this wireless network system, if a mobile communication device (Mobile Station, MS) 510, 520 or 530 wants to communicate with other mobile communication devices, it usually does so through a wireless network access device (Access Point, AP) 500. It is a centralized dissemination station for information. For example, when the mobile communication device 510 ...

Abstract

The invention is a wireless network multicast packet transmitting method, and it adds number of collisions in the multicast downlink packet of the first transmission end and the second transmission end receiving the downlink packet determines the packet uplink delay time according to the number of collisions.

Description

technical field [0001] The present invention relates to a packet transmission method, and in particular to a wireless network packet transmission method. Background technique [0002] In recent years, wireless network systems (Wireless Network) such as wireless local area network (WLAN) and wireless metropolitan network (WMAN) have been developed one after another. (Packet Voice / Video) is regarded as one of the most important application service items on the wireless network system. However, providing instant messaging services (Real-time Communication Services) on wireless network systems faces several challenges. For example, wireless handheld devices are mostly powered by batteries, and the problem of power consumption needs to be overcome; Most of the audio data and audio data are generated regularly and the small packets will have a considerable impact on the bandwidth utilization of the wireless network system. [0003] On the other hand, the design of the wireless n...
