WLAN (Wireless Local Area Network) resource sharing method and WLAN network system

Abstract

The invention discloses a WLAN (Wireless Local Area Network) resource sharing method and a WLAN network system, wherein the method comprises the steps of: broadcast-identifying different access identifiers of each operation network by using an access point device; searching the access identifier of each operation network by users in the operation network respectively and transmitting the searched access identifier and user data to the access point device together; transparently transmitting the received data to an access controller by the access point device; respectively mapping the data to configured VLAN (Virtual Local Area Network) passages corresponding to different access identifiers by the access controller according to the access identifiers in the received data; and respectively transmitting the data of each operation network to a broadband access server of each operation network through a port of the access controller bonded with the VLAN passages. The invention realizes the peer-to-peer fair of resources, the guaranteed network quality, the operation possibility, the controllable possibility and the expandable upgrade of a plurality of telecom operators simultaneously accessed into the WLAN network in the same region.

Description

technical field [0001] The present invention relates to the field of wireless broadband, in particular to a WLAN network resource sharing method and a WLAN network system. Background technique [0002] Broadband network is currently the focus of network construction and operation of various telecom operators, and the current three telecom operators have proposed the demand for WLAN wireless broadband network construction. [0003] Since the WLAN air interface uses open 2.4G frequency resources without application, each telecom operator can freely build a WLAN wireless broadband network based on this frequency resource. According to the IEEE802.11 protocol followed by the WLAN wireless broadband network, 802.11b / g devices work in the 2400-2483.5M frequency band. In order to enable users to access the network smoothly within the coverage of the WLAN wireless broadband network, different WLAN access points (Access Point, AP) coverage may have a certain overlapping area.

Problems solved by technology

Under such a WLAN network, since there are three non-overlapping three channel signals in each hotspot area at the same time, it is necessary to realize the expansion of the WLAN network, such as figure 1 As shown, there is no "pure" channel resource at all. Therefore, even if the WLAN network shared by three operators can be realized through tri-frequency combination, it is still difficult to meet the network expansion and network requirements brought about by multi-user access. The demand for quality assurance will also face the embarrassment that the network cannot be expanded and upgraded after commercial use, which is far from the basic requirements for a carrier-class network to be operable, controllable, and expandable.
