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.
