Backhauling of traffic from 3gpp and non-3gpp based radio access technologies via new radio integrated access backhaul for 5g or other next generation network

Abstract

Various embodiments disclosed herein provide for the provisioning of backhaul links over a 5G NR (New Radio) integrated access and backhaul (IAB) network for access nodes using non-5G radio access technologies. In this way, the IAB network can service devices that are connected to the core network via older 3GPP technologies, or even non-3GPP technologies such as Wi-Fi. An IAB mobile terminal can be provided at the end point access node to make the access node an IAB node. Using an existing internet protocol (IP) routing in the IAB network, or providing for an IP tunnel between the endpoint access node and the core network can then facilitate providing backhaul services for the non-5G access node.
