The invention relates to a method, a device and a digital switch for switching between active and standby links. The method includes: acquiring the current air interface status information of the radio frequency unit in the active link; when it is determined that the radio frequency unit is abnormal according to the air interface status information, sending a backup switching instruction to the control unit of the backup link; wherein, the backup switching instruction is used for Instruct the control unit of the standby link to activate the radio frequency unit of the standby link; control the data switching unit of the active link, and forward the received service data to the data switching unit of the standby link. According to the air interface status of the radio frequency unit in the main link, when it is determined that the radio frequency unit of the main link is abnormal, the radio frequency unit of the backup link is activated, so that the service data is transmitted and processed through the backup link. While the business data can still be effectively transmitted, the backup link is activated and takes over the business data only under abnormal circumstances, so as to avoid signal transmission interference caused by the simultaneous operation of the main and backup links.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a method, a device and a digital switch for switching between active and standby links. Background technique [0002] With the development of mobile communication technology, in the microwave multi-channel data communication network, the signal transmission link in the near-end unit is expanded from the previous single link to a dual link, which is used to improve the transmission reliability of the near-end unit. When the near-end machine fails, it will have a great impact on the transmission business, and it may cause all the remote machines connected to the near-end machine to fail to work normally. In the near-end device, the radio frequency part of the link is more prone to failure than other parts of the link due to aging or other reasons. Therefore, when the near-end device fails, a certain protection mechanism must be adopted to ensure the reliability of ser...
