1Quantity of substance
If 5G mmW TRP self-backhaul connections are used to meet bandwidth demand, then high-capacity data transmission is achieved, but connection reliability deteriorates due to susceptibility to weather, network traffic, and physical damage
Solution Approach 1:
The patent implements dynamic backhaul reconfiguration where the system automatically detects connection failures and switches between different backhaul paths (wireless mmW, wireless sub-6 GHz, or wired connections) based on real-time network conditions. This dynamic adaptation allows the system to maintain high bandwidth utilization while compensating for connection reliability issues through automated failover mechanisms.
Solution Approach 2:
The system changes operational parameters by switching between different frequency bands (mmW to sub-6 GHz) and connection types (wireless to wired) in response to detected failures. The SDN controller dynamically adjusts network parameters including bandwidth allocation, connection mode, and path selection to maintain reliable high-capacity transmission despite environmental challenges.
2Reliability
If automated backhaul reconfiguration is implemented to improve reliability, then service continuity is enhanced, but system complexity increases due to additional monitoring and control mechanisms
Solution Approach 1:
The patent implements self-service automation where the system autonomously detects backhaul failures, selects alternative paths, and executes reconfiguration without human intervention. The automated monitoring and control mechanisms operate independently, reducing the need for complex manual management while maintaining service continuity through self-healing capabilities.
Solution Approach 2:
The system employs feedback loops where the SDN controller continuously monitors backhaul connection status and automatically adjusts network configuration in response to detected failures. This closed-loop control enables reliable service continuity through automated response to network conditions, managing complexity through systematic feedback-based decision-making.
3Reliability
If dynamic reconfiguration mechanisms are added to handle connection failures, then network resilience is improved, but latency increases due to additional detection and switching operations
Solution Approach 1:
The patent implements preliminary actions by pre-configuring multiple backhaul paths and maintaining readiness states for alternative connections. The system prepares fallback options in advance, allowing rapid switching when failures occur, thereby reducing reconnection latency while maintaining network resilience through pre-established recovery mechanisms.

AI summary
Various embodiments disclosed herein that facilitate a dynamic self-backhaul reconnection using a radio resource control messaging. According to some embodiments, a system can comprise detecting a failure in a first backhaul communication link with a first node device, wherein the first node device is communicatively connected to a core network device of a core network, selecting a second node device, other than the first node device, that is communicatively connected to the core network device for establishment of a second backhaul communication link to replace the first backhaul communication link, and facilitating establishing a first connection with the second node device to provide an indication of the failure of the first backhaul communication link, to provide a confirmation that the second node device is available in connection with establishment of the second backhaul communication link, and to request to reserve resources to establish the second backhaul communication link with the second node device.
