Solution Overview
Problem
Existing band assignment methods in wireless networks fail to consider the transmission characteristics of wireless devices in conjunction with congestion at different ports of a cell site router, leading to inefficient resource allocation and network performance issues.
Innovation Solution
A method and system that identify congestion parameters and device characteristics to dynamically assign wireless devices to appropriate CSR ports based on their characteristics and congestion levels, optimizing resource allocation by assigning high power class devices to congested ports and low power class devices to less congested ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing band assignment methods are used, then resource allocation is simple, but network performance deteriorates due to inefficient resource allocation and packet drops
Solution Approach 1:
The system performs preliminary identification of device characteristics (power class, capability) and congestion parameters before making band assignment decisions. This allows the network to proactively assign devices to appropriate bands based on predicted performance needs rather than reacting to failures, improving reliability while maintaining manageable complexity through structured pre-assessment
Solution Approach 2:
The band assignment becomes dynamic by continuously monitoring device characteristics and congestion parameters, then adapting assignments in real-time. The system can transition devices between different bands and RATs based on changing network conditions and device capabilities, resolving the contradiction by making the system flexible rather than static
2Reliability
If high power class devices are assigned to congested ports, then transmission reliability improves in poor RF conditions, but resource allocation complexity increases
Solution Approach 1:
The system applies different assignment strategies to different devices based on their local characteristics (power class, capability) and local congestion conditions. High power class devices are specifically targeted for assignment to congested ports where their transmission capability provides advantage, while other devices receive appropriate assignments based on their specific needs, resolving the contradiction through localized optimization rather than uniform complexity
Solution Approach 2:
The system changes assignment parameters (band, RAT, port) based on device power class and congestion parameters. By dynamically adjusting these parameters according to measured conditions, the system achieves improved transmission reliability for high power devices on congested ports without permanently increasing system complexity, as the complexity is managed through parameter-based decision rules
3Productivity
If band assignment considers device characteristics and congestion parameters, then network efficiency improves, but assignment decision complexity increases
Solution Approach 1:
The system segments the assignment decision process into distinct components: identifying device characteristics, identifying congestion parameters, and making assignment decisions based on these inputs. This segmentation allows each component to be managed independently, improving network efficiency through comprehensive consideration while controlling overall complexity by breaking the decision process into manageable parts
Solution Approach 2:
The system uses feedback from device characteristics and congestion parameters to drive assignment decisions. By continuously monitoring these parameters and using them to inform subsequent assignments, the system improves network efficiency through adaptive decision-making while managing complexity through structured feedback loops rather than uncontrolled complexity

AI summary
A method and system identify a congestion parameter for multiple ports of a cell site router (CSR) and determine a characteristic of a wireless device communicating using the CSR. The method and system further assign the wireless device to a port of the CSR based on the characteristic of the wireless device and the congestion parameter. The method and system have the effect of assigning wireless devices having more capabilities to ports having the most congestion as the more capable devices are more likely to have sufficient retransmission power in the event of congestion.
