Solution Overview

Problem

Existing communication technologies cannot effectively adjust backhaul links to meet the dynamic data forwarding requirements of mobile network nodes in movement scenarios, as the backhaul links and data paths are typically fixed and cannot adapt to changing network loads or locations.

Innovation Solution

A mobile node system that includes a processor to obtain current operating status information and send adjustment requests to backhaul nodes, determining the optimal backhaul resource allocation based on movement instructions and operating status, such as quality of service, bandwidth, or electricity quantity, to dynamically adjust the backhaul link and select suitable candidate backhaul nodes within a specified threshold.

AI summary

The present invention discloses a backhaul link adjustment method, a mobile device, and a system. The backhaul link adjustment method is applied to a mobile node, and the method includes: obtaining, by the mobile node, current operating status information used to indicate a current operating status of the mobile node; sending, by the mobile node based on the current operating status information, an adjustment request used to adjust a backhaul link between the mobile node and a backhaul node to the backhaul node; receiving, by the mobile node, feedback information sent by the backhaul node, where the feedback information includes a backhaul resource allocated to the mobile node; and adjusting, by the mobile node, the backhaul link based on the backhaul resource. In the foregoing technical solution, the mobile node adjusts the backhaul link based on the backhaul resource, which resolves a technical problem in the prior art that a backhaul link cannot satisfy a data forwarding requirement of a mobile network node in a movement scenario.
