Abstract
This document describes monitoring and managing wireless backhaul integrated with mobile access in fifth generation new radio (5G NR) wireless networks. The techniques described employ an Integrated Backhaul-Access and Mobility Function (IB-AMF) to enable authorization of a base station to access a 5G network through another base station. The techniques described also monitor channel conditions and traffic loads to manage backhaul links and facilitate handovers of base station backhaul connections between other base stations.
Claims20
A system comprising:
- multiple relay base stations;
- a base station configured to backhaul user-plane and control-plane communications of a wireless communications network via one or more of the multiple relay base stations;
- and
- an Integrated Backhaul Access and Mobility Function (IB-AMF) server connected to the multiple relay base stations and configured to:
- receive monitoring data from the base station, a first relay base station, or both for a wireless backhaul link between the base station and the first relay base station;
- based at least in part on the received monitoring data, determine to handover the wireless backhaul link from the first relay base station to a second relay base station;
- allocate resources for the wireless backhaul link between the base station and the second relay base station;
- and
- transmit handover trigger messages to the base station, the first relay base station, and the second relay base station, the transmission being effective to cause the handover of the wireless backhaul link from the first relay base station to the second relay base station.
A method for managing wireless backhaul links in a wireless communications network by an Integrated Backhaul Access and Mobility Function (IB-AMF) server, the method comprising the IB-AMF server:
- receiving monitoring data from a base station, a first relay base station, or both for a wireless backhaul link between the base station and the first relay base station;
- based at least in part on the received monitoring data, determining to handover the wireless backhaul link from the first relay base station to a second relay base station;
- allocating resources for the wireless backhaul link between the base station and the second relay base station;
- and
- transmitting handover trigger messages to the base station, the first relay base station, and the second relay base station, the transmitting being effective to cause the handover of the wireless backhaul link from the first relay base station to the second relay base station.
An Integrated Backhaul-Access and Mobility server device comprising:
- one or more processors;
- and
- a memory comprising instructions for an Integrated Backhaul Access and Mobility Function application, the instructions executable by the one or more processors to configure the one or more processors to:
- receive monitoring data from a base station, a first relay base station, or both for a wireless backhaul link between the base station and the first relay base station;
- based at least in part on the received monitoring data, determine to handover the wireless backhaul link from the first relay base station to a second relay base station;
- allocate resources for the wireless backhaul link between the base station and the second relay base station;
- and
- transmit handover trigger messages to the base station, the first relay base station, and the second relay base station, the transmitting being effective to cause the handover of the wireless backhaul link from the first relay base station to the second relay base station.
