Aggregator Controller Dynamic Coverage Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular network technologies face challenges in efficiently extending coverage at cell edges without requiring additional fixed radio equipment, which is costly and logistically complex to deploy and maintain.
Innovation Solution
A system that dynamically assigns communication devices as aggregators to establish aggregation connections, using an aggregator controller to instruct devices to act as relays and extend network coverage without the need for dedicated software in eNodeBs, allowing for dynamic deployment and user-controlled positioning of aggregators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If fixed small cells are installed to extend coverage, then network coverage is improved, but device complexity and deployment cost increase
Solution Approach 1:
The patent enables user equipment to autonomously act as aggregators by selecting partner cells and establishing connections without network operator intervention. This self-service mechanism eliminates the need for manual deployment, site surveys, and professional installation required by fixed small cells, thereby extending coverage without increasing deployment complexity
Solution Approach 2:
The patent dynamically changes the operational parameters of existing user equipment by assigning aggregator roles based on real-time network conditions, device capabilities, and location. This allows the system to adapt coverage capacity without adding fixed infrastructure, converting ordinary devices into coverage-extending nodes through parameter reconfiguration rather than physical deployment
2Area of stationary object
If aggregators are deployed to extend coverage, then network coverage is improved, but interference increases
Solution Approach 1:
The patent implements continuous monitoring of interference levels, signal quality, and network performance by the aggregator controller. Based on this feedback, the system dynamically adjusts aggregator configurations, partner cell selections, and resource allocations to maintain optimal performance while minimizing interference. This closed-loop control prevents interference from escalating as coverage is extended
Solution Approach 2:
The patent enables different aggregators to operate with customized parameters tailored to their local environment, including frequency selection, power levels, and partner cell choices. This local optimization ensures that each aggregator adapts to its specific interference conditions rather than applying uniform settings across all coverage areas, thereby extending coverage while managing interference locally
3Productivity
If dynamic aggregator assignment is implemented, then resource efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces an aggregator controller as an intermediary entity that manages the complexity of dynamic aggregator assignment. This mediator coordinates between the core network, user equipment, and aggregators, handling device selection, configuration, and performance monitoring. By centralizing control functions, the system achieves high resource efficiency without distributing complex decision-making logic across all network elements

AI summary
A cellular telecommunications network architecture is described where certain UEs are configured to assist the network to improve coverage in regions of poor radio conditions. In certain embodiments, appropriate UEs are selected to act as a dynamic, out-of-band coverage extensions. Network performance can thereby be improved when serving users at the cell edge (or in other poor radio condition regions of a cell).
