Abstract

Embodiments of the present invention provide a backhaul path conversion method, a wireless relay, a network side node, and a terminal. In the embodiment of the present invention, by pre-establishing the second backhaul path, the backhaul path is switched when the wireless link fails or the quality of the related wireless relay signal does not meet the requirements. In the embodiment of the present invention, a plurality of backhaul paths are pre-established for the terminal, which can save the time for re-establishing the backhaul path during path switching, increase the speed of path switching, and quickly resume data transmission of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a return path conversion method, a wireless relay, a network side node and a terminal. Background technique [0002] In the fifth generation mobile communication (5G) system, the wireless relay is used as the node device of the backhaul network. The wireless relay backhaul technology includes a wireless backhaul link that adopts a high-frequency band above 6GHz. Wireless relay (Relay) backhaul technology, by adding one or more wireless relay nodes between the network side node and the terminal, realizes one or more relay forwarding of wireless signals, that is, wireless signals usually go through It takes multiple hops to reach the terminal. [0003] Taking a simple two-hop relay as an example, a link from a node on the network side to a terminal is usually divided into two links from the node on the network side to the relay and the link from the relay to th...
