Anchoring Relationships Management for 4G-5G Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially those transitioning to 5G NR, the lack of established anchoring relationships between 4G and 5G base stations can prevent FWA devices from attaching to 5G base stations, leading to connectivity issues due to finite RAN resources and limited hardware/software configurations.
Innovation Solution
An anchoring relationships management system that creates, updates, and removes anchoring relationships between 4G and 5G base stations based on criteria such as geographical proximity, using a device that receives reports from FWA devices about missing relationships, and manages the creation and expiration of these relationships through a database, ensuring optimal network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If anchoring relationships are manually configured between 4G and 5G base stations, then network control precision is improved, but system complexity and configuration time increase
Solution Approach 1:
The system enables automatic self-configuration of anchoring relationships between 4G and 5G base stations. When a 5G base station is deployed, it automatically identifies suitable 4G anchor base stations based on geographical proximity and network conditions, eliminating the need for manual configuration while maintaining precise network control
Solution Approach 2:
The system pre-establishes a database of 4G base station information including geographical data and network status before 5G deployment. This preliminary data preparation enables automatic anchoring relationship establishment when 5G base stations are deployed, reducing configuration time and complexity
2Device complexity
If anchoring relationships are automatically established based on geographical proximity, then system complexity is reduced, but anchoring relationship accuracy may deteriorate
Solution Approach 1:
The system uses multiple parameters beyond just geographical proximity to determine anchoring relationships, including network load, signal strength, and base station capacity. This multi-parameter evaluation maintains anchoring accuracy while preserving the simplicity of automatic configuration
Solution Approach 2:
The system continuously monitors the performance of established anchoring relationships and uses this feedback to optimize future selections. If an anchoring relationship performs poorly, the system can adjust and re-establish relationships based on improved criteria, maintaining high accuracy
3Area of stationary object
If more base stations are deployed to expand network coverage, then network coverage area is improved, but resource management complexity increases
Solution Approach 1:
The system segments the network into distinct 4G and 5G base station domains with clear anchoring relationships. This segmentation allows independent management of each domain while maintaining coordinated operation through standardized interfaces, reducing overall management complexity as the network expands
Solution Approach 2:
The anchoring relationship framework provides a universal mechanism that works across different base station types and network configurations. This standardized approach enables consistent resource management practices to be applied throughout the expanding network, reducing complexity despite increased scale
4Productivity
If dynamic anchoring relationships are implemented to optimize resource allocation, then network efficiency is improved, but system stability may worsen
Solution Approach 1:
The system implements dynamic anchoring relationships that can adapt to changing network conditions such as load variations and signal quality. This dynamic capability optimizes resource allocation while maintaining stability through controlled adjustment mechanisms that preserve critical connections
Solution Approach 2:
The system establishes multiple potential anchoring relationships and maintains backup configurations in advance. This cushioning approach allows the system to switch between anchor base stations if conditions change, maintaining stability while enabling dynamic optimization

AI summary
A device may include a processor configured to receive a report from a fixed wireless access device indicating that no anchoring relationship exists between a Fourth Generation (4G) base station and a Fifth Generation (5G) base station to which the fixed wireless access device is attempting to connect. The device may be further configured to instruct a network management system to create the anchoring relationship between the 4G base station and the 5G base station; and update an anchoring relationships database with information relating to the created anchoring relationship, wherein the anchoring relationships database stores information relating to anchoring relationships between base stations in a radio access network.
