Problems solved by technology

[0005] But when figure 1 In the MSTP ring structure shown, there is a link between a base station and an MSTP device, and there is also a link between a base station controller and an MSTP device. If the link between the base station and the MSTP device is interrupted due to the link itself , it will cause the base station to lose the connection with the MSTP device, which will cause the base station to be unable to connect to the base station controller; if the link between the base station controller and the MSTP device is interrupted due to the link itself, it will cause the base station Incoming base station backhaul transmission system, which causes the base station controller to lose contact with the base station that accesses itself
When the links between multiple base stations, base station controllers and MSTP equipment are interrupted, it is likely to cause the communication link to be paralyzed

Embodiment 2

[0039] The second embodiment is a preferred implementation of the present invention. It is assumed that the wireless network access device in the second embodiment is a base station, and the base station is connected to an MSTP device in the base station backhaul transmission system, such as image 3 Shown is a schematic diagram of the step flow of the second embodiment of the present invention:

[0040] Step 201: The base station establishes multiple links with the MSTP device, and initially one of the links is used as a working link, and the link with it is used as a backup link.

[0041] Both the base station and the MSTP equipment simultaneously record the related information of the working link and the related information of the standby link. The related information of the link includes the identification of the link, the port information when the base station uses the link, and the port information when the MSTP device uses the link.

[0042] Step 202: The base station monitors...

Abstract

The invention discloses a method for transmitting data by a wireless link, which comprises that: wireless network access equipment monitors an active link between the wireless network access equipment and a base station back transmission system; when the active link is determined to fail, the wireless network access equipment transmits a link switching request message to the base station back transmission system by using a pre-established backup link; and after receiving confirmation information returned by the base station back transmission system, the wireless network access equipment performs data transmission with the base station back transmission system by using the backup link. The method has the advantage of ensuring the security of the link between the wireless network access equipment and the base station back transmission system. The embodiment of the invention also provides a system and equipment for transmitting the data by the wireless link.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method, system and equipment for transmitting data through a wireless link. Background technique [0002] The wireless links between the base station (BTS / NodeB) and the base station controller (BSC / RNC) are mostly established through the base station backhaul transmission system. In order to ensure the reliability of the base station business, the base station backhaul transmission system has set up related protection mechanisms. In order to avoid the base station backhaul transmission system's own failure (such as node failure or fiber cut, etc.) causing damage to the wireless services carried by the wireless link. [0003] The base station backhaul transmission system architecture can be an MSTP ring structure formed by Multi-Service Transmission Platform (MSTP) equipment, such as figure 1 As shown, there are multiple MSTP devices in the MSTP ring structure. One MSTP device ca...
