Embodiment Construction

[0060] Embodiments of the present invention provide a data tunnel establishment method and an AP under a public WLAN architecture. In a scenario where WLANs are co-constructed and shared, and data tunnels and control tunnels are separated, by creating multiple data tunnels as active and standby, when the primary data tunnel fails Finally, the data traffic is switched to the backup data tunnel to ensure the normal transmission of data traffic and enhance the reliability of the WLAN network; or, it is also possible to create multiple load-balanced data tunnels to balance the burden of data traffic and avoid traffic congestion. .

[0061] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and various embodiments.

[0062] refer to figure 2 As shown, in the scenario where WLAN is co-constructed and shared, and the data tunnel and the control tunnel are separated, the overview process of establishing the data tun...

Abstract

The invention discloses a data tunnel establishment method and an access point AP under a public WLAN architecture. By creating multiple data tunnels, the normal transmission of data traffic is ensured, traffic congestion is avoided, and the reliability and traffic load balancing capability of the WLAN network are enhanced. . The method is as follows: the AP receives a configuration message sent by the access controller AC for instructing to create multiple data tunnels; the multiple data tunnels correspond to the same starting point; the AP determines the starting point according to the configuration message , and respectively determine the termination point of each data tunnel in the plurality of data tunnels; the AP establishes the plurality of data tunnels according to the starting point and the termination point of each data tunnel.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data tunnel establishment method and an access point (English: Access Point, abbreviated: AP) under the framework of a public wireless local area network (English: Wireless Local Area Network, abbreviated: WLAN). Background technique [0002] With the rapid growth of demand for data services, and due to the limited data carrying capacity of the second generation (English: 2nd Generation, referred to as: 2G) and third generation (English: 3nd Generation, referred to as: 3G) wireless networks, data distribution through WLAN Business has become the preferred solution for operators. [0003] A network structure based on the WLAN technology usually includes devices such as a station (English: Station, STA for short), an AP, an access controller (English: Access Controller, AC for short), and the like. Among them, the role of the AP is to connect the STA to the wired ...
