Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The inventor believes that although a frame loss may occur when an AP is used to forward MN traffic, other APs in the same wireless network may still receive the lost frame. Therefore, the above properties of the wireless network can be used to allow multiple APs to forward the traffic of the same MN, thereby reducing the frame loss rate. In addition, a de-redundancy operation can be performed on the resulting duplicate traffic.

[0045] At the same time, for the consideration of improving energy efficiency (for example, in order to ensure the signal strength of the corresponding downlink), the AP with the best wireless performance can be selected for a MN as the main AP for the MN, and the main AP provides a higher transmit power for traffic forwarding; and select other one or more APs (which may be one or more APs with suboptimal wi...

Abstract

The invention provides a method for reducing wireless communication frame loss and equipment thereof. The method comprises the steps that a master access point is selected for a terminal; one or multiple slave access points are selected for the terminal; and the slave access points forward traffic from the terminal received by the slave access points. The equipment comprises the master access point which is selected for the terminal; one or multiple slave access points which are selected for the terminal; and intermediate equipment which receives the traffic from the terminal from the master access point and the slave access points and forwards the traffic. According to the method and the equipment, wireless communication frame loss, especially the problem of high frame loss rate existing in an application of voice videos having high requirement for an uplink, can be reduced.

Description

technical field [0001] The present invention relates to wireless communication, in particular to SDN-based wireless network communication. Background technique [0002] Wireless Local Area Networks (WLAN) is a local area network that uses radio waves as a data transmission medium. The difference between wireless LAN and wired LAN is mostly determined by the sharing characteristics of the medium, the half-duplex working characteristics of the wireless network card, and the signal propagation characteristics of the physical layer. A typical WLAN includes two types of equipment: mobile terminals (Mobile Node, MN) connected to the wireless network, and access points (Access Point, AP) that provide mobile terminals with access to wired LANs and from wired LANs to mobile terminals . [0003] In a large organization, a WLAN may include hundreds or thousands of APs to provide network services for a large number of users. However, in actual usage scenarios, due to the requirement ...
