Uplink wireless access method and wireless access network bridge device

Abstract

The invention discloses an uplink wireless access method and a wireless access network bridge device. The method comprises the following steps of: creating a plurality of wireless clients on an uplink wireless interface of the wireless access network bridge device and closing a WDS (Wireless Distribution System) function of each wireless client, wherein the steps are realized by the following substeps of: A, judging whether a subscriber main machine is bound with a wireless client or not if a message needs to be transmitted through an uplink wireless interface when the wireless access network bridge device receives the message coming from the subscriber main machine from a downlink wired interface or a downlink wireless interface, executing a step C if YES, and otherwise, executing a step B; B, searching a free wireless client in the wireless clients by the device, and binding the wireless client with the subscriber main machine; and C, sending the message to the bound wireless client after NAT (Network Address Translation) processing is carried out on the message by the device, packaging the message by the wireless client in a 3-address mode, and sending out the packaged message. According to the invention, the configuration complexity of the wireless access network bridge device is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless access, in particular to an uplink wireless access method and a wireless access bridge device. Background technique [0002] In a wireless network, operators provide Internet (Internet) access services for wireless users through access controllers (AC, Access Controller) and portal (Portal) servers. With wireless hotspot coverage in different areas, wireless users can finally access Internet resources by accessing regional APs and passing Portal authentication on the AC. figure 1 A typical networking diagram for wireless network access is given. [0003] However, due to the shortcomings of the wireless transmission medium itself, such as susceptibility to interference and poor penetration capability, the coverage quality of wireless signals in some buildings or remote areas is poor, and it cannot provide reliable Internet access services for final wireless users. Therefore, it is necessary to d...

Problems solved by technology

[0013] 2) The uplink wireless port is connected to the AP in the wireless area, but no Layer 3 address is configured;

[0024] Authentication and accounting security issues: Since the uplink wireless port is used as a router port and works in NAT mode, when multiple users in the downlink network need to access Internet resources at the same time, the IP address and MAC address used after they access the uplink network Both are the IP address and MAC address of the uplink wireless interface of the wireless access bridge device, and the AC side in the uplink wireless network cannot provide independent authentication and accounting functions for each user

This problem will have hidden dangers in security and billing when operators carry out business promotion
