==MANAGEMENT OF RADIO LINK FAILURE AND DEFICIENCIES IN INTEGRATED ACCESS BACKHAULED NETWORKS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240056940 titled 'MANAGEMENT OF RADIO LINK FAILURE AND DEFICIENCIES IN INTEGRATED ACCESS BACKHAULED NETWORKS

==Simplified Explanation==

The abstract describes a method in an IAB network where an IAB-node detects a deficiency or failure of a backhaul link and sends a message to its child IAB-nodes, sharing the impacted paths and quality of those paths, as well as the deficient radio link.

* Detection and notification of backhaul link failure in an IAB network
* Transmission of messages to affected IAB-nodes and sharing IAB-node to adapt routing configuration
* Rerouting of impacted backhaul paths using alternative paths
* Application of routing strategies by IAB-nodes for impacted paths based on indicated quality
* Restoration of original routing configuration when backhaul link recovers

**Potential applications of this technology:**
- Wireless communication networks
- Internet of Things (IoT) networks
- Smart city infrastructure

**Problems solved by this technology:**
- Efficient detection and handling of backhaul link failures in IAB networks
- Minimization of network downtime and packet loss
- Dynamic adaptation of routing configurations to network topology changes

**Benefits of this technology:**
- Improved network reliability and resilience
- Enhanced quality of service for connected devices
- Optimal utilization of network resources


==Original Abstract Submitted==

in an iab network, an iab-node detects a deficiency or failure of one bh link. a bh rlf indication message is sent to its child iab-nodes specifying the bap paths that are impacted, a quality of those paths and the deficient radio link by indicating the other iab-node sharing the link. same message are transmitted to this sharing iab-node, but also to the iab-donor in order to adapt the routing configuration of the iab-nodes to the topology. bap packets for the impacted bap paths are rerouted using alternative bap paths. iab-nodes receiving the bh rlf indication message also apply routing strategies for the impacted bap paths, taking into account the indicated quality. a similar message is transmitted when the bh radio link experiences recovery, so that the iab-nodes stop rerouting the bap packets and the iab-donor restore the original routing configuration.
