Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in managing spectrum resource sharing efficiently, leading to increased radio interference and reduced capacity due to the limited density of base stations and high operational costs, as well as inefficient frequency allocation practices.
Innovation Solution
A system where user equipment (UE) can dynamically switch to better performing frequency bands offered by federated network nodes, allowing for a 'reverse auction' process to optimize data service pricing and directly hand off between network nodes, thereby increasing network capacity without adding physical base stations.

Engineering Contradiction Analysis
1Productivity
If the density of base stations is increased to improve network capacity, then network capacity is improved, but operational costs increase
Solution Approach 1:
The patent enables base stations to serve multiple network operators simultaneously through federated network architecture. A single physical base station infrastructure is shared across multiple operators, allowing each operator to utilize the same physical resources (tower, radio equipment, power supply) for their respective networks. This multi-functional use of infrastructure increases network capacity for all operators without requiring each operator to build and operate separate base stations, thereby avoiding increased operational costs.
2Productivity
If spectrum resource sharing is implemented to increase network capacity, then network capacity is improved, but radio interference increases
Solution Approach 1:
The patent implements dynamic spectrum sharing through reverse auction mechanisms where network parameters (frequency band allocation, power levels, time slots) are continuously adjusted based on real-time conditions. The system monitors signal-to-noise ratios and interference levels, then reallocates spectrum resources to optimize performance. This dynamic parameter adjustment allows multiple operators to share spectrum efficiently while maintaining acceptable interference levels through coordinated resource management.
3Stability of the object's composition
If traditional frequency allocation practices are used to manage spectrum, then network stability is maintained, but spectrum resource sharing efficiency is reduced
Solution Approach 1:
The patent transitions from static frequency allocation to dynamic spectrum management through reverse auction processes. Instead of fixed assignments, the system continuously evaluates spectrum demand and supply conditions, allowing frequency allocations to change dynamically based on real-time network conditions and user demand. This dynamic approach maintains network stability through controlled transitions while dramatically improving spectrum sharing efficiency by allocating resources to where they are most needed.

AI summary
Spectrum resource sharing management is described, e.g., a user equipment can determine a metric representative of a quality of a communication signal received by the user equipment, wherein the communication signal is received via a first mobile network operated by a first mobile network operator entity. In response to the metric being determined to be below a threshold, the user equipment can scan a group of frequency bands. The user equipment can receive a broadcast signal from a network node device via a frequency band of the group of frequencies, wherein the broadcast signal comprises a performance parameter and cost information, and wherein the network node device is associated with a second mobile network operated by a second mobile network operator entity. In response to an evaluation of the performance parameter and the cost information, the user equipment can determine whether to select the network node device to engage in cellular transmissions between the user equipment and the network node device.
