Backhaul path construction method and device

Abstract

The invention provides a backhaul path construction method and a backhaul path construction device, which are used for reducing the complexity and overhead of a wireless backhaul network topology andimproving the service transmission efficiency. The method comprises the following steps that: any relay node in the wireless backhaul network receives a priority parameter of the relay node broadcasted by each node in at least one other node around the relay node; wherein the smaller the priority parameter of the node is, the higher the priority corresponding to the node is; the priority parameterof any relay node is read from the OAM configuration; other nodes of which the cell signal strength meets a preset condition and the priority parameter is less than or equal to the priority parameterof any relay node are screened from the at least one other node; and the next hop node of any relay node in the direction leading to the anchor point base station node is determined from the other screened nodes.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for constructing a backhaul path. Background technique [0002] In order to better meet user needs and improve network capacity and throughput, a wireless relay node (Integrated Access and Backhaul Node, IAB Node) is introduced into the wireless backhaul network. However, the existing technology does not impose constraints on the topology of the wireless backhaul network. Therefore, when deploying a wireless backhaul network, operators may deploy simple linear topologies, star topologies, tree topologies, etc., or more complex ones. Mesh topology, such as figure 1 , any IAB Node in this network topology may have multiple paths leading to the anchor base station node. Such a wireless backhaul network topology has high complexity and high overhead. When performing business, it is likely that the return path will be detoured far away, resulting in lo...

However, the existing technology does not impose constraints on the topology of the wireless backhaul network. Therefore, when deploying a wireless backhaul network, operators may deploy simple linear topologies, star topologies, tree topologies, etc., or more complex ones. Mesh topology, such as figure 1 , any IAB Node in this network topology may have multiple paths leading to the anchor base station node. Such a wireless backhaul network topology has high complexity and high overhead. When doing business, it is likely that the return path will be detoured far away, resulting in low service transmission efficiency
