Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The method provided by the present invention mainly includes: when the mobile MP receives the signal quality of the fixed MP is greater than or equal to the preset saturation signal quality, making the MESH link between the mobile MP and the fixed MP and the fixed MP enter a saturated state ; When the mobile MP receives the signal quality of the fixed MP less than the saturation signal quality and greater than the preset maintenance signal quality, the MESH link between the mobile MP and the fixed MP enters an unsaturated state; the mobile MP receives from the mobile MP Select one of the MESH links in the unsaturated state with each fixed MP as the main link, and the remaining unsaturated MESH links as the backup link; when the preset switch...

Abstract

The invention provides a communication method of a wireless mesh network (MESH) and a movable access point (MP). When the signal quality of a fixed MP received by the movable MP is larger than or equal to the preset saturation signal quality, a MESH link between the movable MP and the fixed MP is entered into the saturated status, and the connection status of the MESH interlinkage is remained without being removed, so that the MESH interlinkage can enter into the unsaturated status after the saturation interval and can be fast switched to be a main link under the situation that a switching condition is met, thereby preventing from the detecting and negotiating time consumed by rebuilding the MESH interlinkage of the fixed MP and guaranteeing the data transferring quality. Furthermore, a main interlinkage is always selected in the MESH interlinkage under the unsaturated status, namely, the MESH interlinkage of the saturated status has to be switched into the standby interlinkage to be further switched into the main interlinkage, thereby effectively preventing the main interlinkage from being frequently switched.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a communication method of a wireless mesh (MESH) network and a mobile access point (MP). Background technique [0002] In traditional wireless local area network (WLAN) technology, each access point (AP) is connected through a wired network, and a wireless terminal (STA) is connected to a wired backbone network with a single-hop wireless connection. With the development of wireless technology, the wireless mesh (MESH) network has gradually been widely used because of its advantages of flexible and convenient networking. In a MESH network, there may be either a wired connection or a wireless connection between APs. APs that support the MESH function are generally called MPs, and wireless links established between MPs are called MESH links. A fixed MP connected through a wired network is called a fixed MP, and a mobile MP connected with other MPs through wireless i...
