ROUTING DATA IN AN INTEGRATED ACCESS AND BACKHAUL NETWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18554431 titled 'ROUTING DATA IN AN INTEGRATED ACCESS AND BACKHAUL NETWORK
The patent application describes a method for routing data packets over wireless backhaul links in an integrated access and backhaul (IAB) network, which includes a donor network node with a donor CU and multiple donor DUs, as well as several IAB network nodes.
- Each donor DU and IAB network node are assigned unique addresses.
- Donor DUs are grouped with unique group identifiers.
- IAB network nodes are configured with routing configuration information, including addresses of donor DUs, routing paths, and group identifiers.
- The method involves receiving a data packet for a destination donor DU, determining an available routing path based on the packet's address and path identifier, and routing the packet accordingly.
- If no direct path is available, an alternate routing path to a different donor DU in the same group is determined and used.
- Potential Applications:**
- Wireless network infrastructure - Mobile communication systems - Internet of Things (IoT) networks
- Problems Solved:**
- Efficient routing of data packets in complex network topologies - Optimizing data transmission over wireless backhaul links
- Benefits:**
- Enhanced network performance - Improved data packet delivery - Scalability in network expansion
- Commercial Applications:**
Title: "Enhanced Wireless Backhaul Routing Method for IAB Networks" This technology can be utilized by telecommunications companies, network operators, and IoT service providers to optimize data transmission in wireless networks, improving overall network efficiency and performance.

Original Abstract Submitted
A method, at an IAB network node, for routing data packets over one or more wireless backhaul links in an integrated access and backhaul, IAB, network comprising a donor network node, having a donor CU and a plurality of donor DUs, and a plurality of IAB network nodes is disclosed. Each donor DU and IAB network node are assigned a unique address and each donor DU is assigned to one of one or more groups with a unique group identifier assigned to each group of the one or more groups. The IAB network node is configured with routing configuration information including a unique address of at least one donor DU corresponding to at least one destination donor DU, at least one path identifier identifying at least one routing path to the at least one destination donor DU, the unique address of a donor DU or IAB network node of the IAB network that is a next node in the at least one routing path and the group identifier associated with the at least one destination donor DU. The method comprises: receiving a data packet for a destination donor DU, the data packet including the unique address of the destination donor DU for the data packet and a path identifier identifying the routing path to the destination donor DU; determining whether there is an available routing path to the destination donor DU based on the unique address of the destination donor DU and the path identifier included in the data packet and the routing configuration information, and based on the unique address of the destination donor DU included in the data packet and the routing configuration information. When no available routing path is determined, the method further comprises determining an alternate routing path for the data packet for the destination donor DU using the routing configuration information and based on the unique address of the destination donor DU and the group identifier associated with the destination donor DU, wherein the alternate routing path is to a different destination donor DU in the same group as the destination donor DU with the same group identifier; and routing the data packet using the determined alternate routing path.
