Innovation Solution
A system and method for managing backhaul connection establishment and modification using a Mobile Wireless Access Backhaul (MWAB) entity, which includes a Mobile Wireless Access Backhaul gNB (MWAB gNB) and an Operations Administration and Maintenance (OAM) server to dynamically configure and manage N2, N3, and Xn interfaces based on location and traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static gNB entities with fixed connections are used, then network stability is maintained, but network flexibility and scalability are limited
Solution Approach 1:
The patent implements dynamic backhaul connections where gNB entities can establish and release connections to core network entities based on real-time traffic conditions. The network management entity dynamically determines connection establishment, enabling gNBs to adapt their connectivity rather than maintaining fixed static connections, thus improving network flexibility while managing complexity through centralized control.
Solution Approach 2:
The network management entity performs preliminary configuration and authorization before actual connection establishment. It pre-determines which gNBs should connect to which core network entities based on predicted traffic patterns and network state, allowing gNBs to quickly establish connections without complex real-time negotiation, thereby enhancing flexibility while simplifying connection management.
2Productivity
If static gNB entities are deployed, then deployment simplicity is maintained, but service continuity in high-traffic areas is compromised
Solution Approach 1:
The system enables gNBs to dynamically establish backhaul connections to core network entities based on real-time traffic conditions and network state. This dynamic connectivity allows the network to adapt to fluctuating traffic demands in high-traffic areas, improving service delivery efficiency while maintaining deployment simplicity through automated connection management.
Solution Approach 2:
The network management entity continuously monitors network traffic conditions and uses this feedback to dynamically determine connection establishment between gNBs and core network entities. This feedback mechanism ensures that service delivery efficiency is optimized by adapting connections to actual traffic conditions rather than relying on static pre-configured connections.
3Adaptability or versatility
If fixed connections to core network entities are used, then connection reliability is ensured, but network scalability is limited
Solution Approach 1:
The network management entity performs preliminary authorization and configuration of gNBs before they establish connections to core network entities. This pre-configuration approach enables scalable network growth by allowing new gNBs to be quickly integrated through automated authorization processes rather than complex manual configuration, thus improving scalability while managing configuration complexity centrally.
Solution Approach 2:
gNBs are equipped with self-service capabilities to autonomously establish and release backhaul connections based on their operational needs and network conditions. This self-service mechanism improves network scalability by enabling automated connection management without requiring complex centralized configuration for each connection, reducing overall system complexity while enhancing adaptability.
4Adaptability or versatility
If mobile gNBs are deployed without dynamic configuration, then deployment flexibility is improved, but connection reliability deteriorates
Solution Approach 1:
The network management entity continuously monitors the operational status and traffic conditions of mobile gNBs and uses this feedback to dynamically determine appropriate backhaul connections. This feedback mechanism ensures connection reliability by adapting connections to actual network conditions while maintaining deployment flexibility through automated real-time configuration adjustments.
Solution Approach 2:
The network management entity performs preliminary authorization and configuration of mobile gNBs before they deploy to various locations. This pre-configuration ensures that mobile gNBs have the necessary credentials and parameters established beforehand, maintaining connection reliability even as they move to different locations and establish new backhaul connections dynamically.
