Embodiment Construction

[0035] In the application scenario of 5G routers, users can use the Ethernet port on the router as the wired main link, and use the 5G interface as the backup link of the wired main link. When the wired main link is working normally, the 5G interface in the backup link is in the down state; when the wired main link communication is interrupted, the 5G interface of the backup link will be triggered to dial, so that the device can switch to the backup 5G link for communication. However, due to the particularity of the 5G network, there will be problems in the switching process of the above-mentioned backup link.

[0036] First of all, because the current coverage of 5G base stations is much smaller than that of 4G base stations, and it is currently in the transition stage from non-standalone (NSA) to standalone (SA), the signal quality of 5G networks is unstable. , there will be two situations: the first one, the 5G network can be found and connected, but the line will be dropp...

Abstract

The invention provides a backup link detection method and device, and is applied to the field of 5G network. The method comprises the steps: carrying out the detection of a wireless backup link according to a set period when the communication of a wired main link is normal; if the available frequency band corresponding to the 5G network is searched, judging whether the 5G network meets a backup link access condition or not; when determining that the 5G network meets the backup link access condition, ending the detection; if the 5G network does not meet the backup link access condition, judging whether the 4G network meets the backup link access condition or not; and when determining that the 4G network meets the backup link access condition, ending the detection. In the scheme, if switching to the backup link is needed, switching can be directly carried out according to the detection result of the backup link in the step, so that the time of repeated network searching can be saved, invalid switching can be avoided, and the time delay of switching from the wired main link to the backup link can be reduced.

Description

technical field [0001] The present application relates to the field of 5G networks, and in particular, to a backup link detection method and device. Background technique [0002] With the development of 5G technology, more and more fields have begun to apply 5G technology. For example, 5G technology can be applied to routers, and a 5G interface equivalent to an Ethernet port can be added to the router, that is, an Ethernet port and a 5G port can exist on a 5G router at the same time. In practical application scenarios, users can use the Ethernet port as the wired main link and the 5G interface as the backup link of the wired main link. Switch to the backup link corresponding to the backup wireless 5G interface for communication. At this time, the backup link needs to undertake all the services of the wired main link. [0003] However, due to the particularity of 5G links, using the above-mentioned backup link switching mechanism, the device side cannot perceive the unstabl...
