Problems solved by technology

[0013] In the above scenarios, a common problem is that even if the individual wireless backhaul links are good (e.g. have / provide high bit rates), if the wireless backhaul links are shared and / or interfered, the throughput is likely to be low

Abstract

Processing of wireless links in a wireless backhaul network is provided. Get load information from end user access network and wireless backhaul network. A current network topology of the wireless backhaul network is associated with a current performance value, the current performance value being dependent on the obtained load information. An estimated performance value of the new network topology is provided based on at least one wireless link of the client node that has been redirected from the current hub node section to the new hub node section. In case the estimated performance value is higher than the current performance value, at least one wireless link is redirected according to the new network topology.

Description

technical field [0001] Embodiments presented herein relate to wireless backhaul networks, in particular to methods, network nodes, computer programs and computer program products for handling wireless links in wireless backhaul networks. Background technique [0002] In a communication network, it is challenging to achieve good performance and capacity for a given communication protocol, its parameters and the physical environment in which the communication network is deployed. [0003] For example, traffic growth in communication networks, such as mobile broadband systems, and the equivalent continuous increase in data rates required by end-user access services provided by communication networks may have an impact on how cellular communication networks are deployed. One way to address this growth is to deploy lower powered network nodes, such as micro or pico network nodes, within the coverage area of ​​the macrocell served by the macro network node. An example where such ...
