Solution Overview
Problem
Communication systems face limitations in providing services to multiple wireless devices due to finite communication resources, leading to challenges in balancing bandwidth and service quality, particularly when an access node reaches its maximum capacity.
Innovation Solution
The system determines the number of wireless devices permitted to communicate with an access node by calculating the total bandwidth, spectral efficiency, and throughput, adjusting the throughput to manage the number of connected devices and optimize resource utilization across multiple frequency bands and sectors.

Engineering Contradiction Analysis
1Quantity of substance
If the access node serves more wireless devices, then the system capacity increases, but the service quality and bandwidth per device deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the number of connected wireless devices based on real-time bandwidth availability and service quality metrics. The access node continuously monitors system state and adjusts the number of served devices dynamically, transitioning from static capacity planning to adaptive resource management that responds to changing network conditions.
Solution Approach 2:
The system changes key parameters including bandwidth allocation, spectral efficiency thresholds, and throughput requirements to optimize the balance between number of devices and service quality. By adjusting these parameters based on current network state, the system can serve more devices when conditions permit while maintaining quality standards.
2Reliability
If the access node commits communication resources to maintain minimum service level for each device, then service quality is improved, but the total system capacity decreases
Solution Approach 1:
The patent applies partial action by providing minimum service level guarantees only when necessary, rather than uniformly to all devices at all times. The system determines the number of devices that can be served while meeting minimum thresholds, and adjusts allocations dynamically, providing enhanced service only where and when resource availability permits.
Solution Approach 2:
The system dynamically adjusts the minimum service level commitments based on current bandwidth availability and network conditions. When resources are abundant, more devices can meet minimum thresholds; when resources are constrained, the system selectively maintains service quality for priority devices while managing overall system capacity.
3Productivity
If the access node increases bandwidth allocation, then throughput per device improves, but the number of devices that can be served decreases
Solution Approach 1:
The system changes bandwidth allocation parameters dynamically based on network conditions, device priorities, and service requirements. By adjusting bandwidth, spectral efficiency, and throughput parameters in response to changing conditions, the system optimizes the trade-off between per-device performance and overall system capacity.
Solution Approach 2:
The patent implements dynamic bandwidth management where the access node continuously monitors throughput requirements and adjusts bandwidth allocation accordingly. This allows the system to provide high throughput to fewer devices when necessary while serving more devices with reduced bandwidth when overall system utilization is the priority.

AI summary
A first number of wireless devices in communication with an access node over a first frequency band is determined. A total bandwidth and a spectral efficiency of the first frequency band are determined, and a throughput provided to each of the first number of wireless devices in the communication between the access node and the first number of wireless devices is calculated. Based on the total bandwidth of the first frequency band, the spectral efficiency of the first frequency band, and the throughput provided to each of the first number of wireless devices, a second number of wireless devices permitted to communicate with the access node over the first frequency band is determined. To determine a third number of wireless devices permitted to communicate with the access node over the first frequency band, the throughput provided to each of the first number of wireless devices is adjusted.
