Dynamic Spectrum Arbitration Broker for Network Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for radio frequency spectrum due to wireless communication devices leads to inefficiencies, such as dropped calls and slow internet access, as existing methods fail to dynamically allocate underutilized RF spectrum from networks like those dedicated to emergency services to other networks effectively.
Innovation Solution
Implementing a dynamic spectrum arbitrage system that includes methods for broadcasting availability of telecommunication resources, determining lease criteria, selecting network configurations, and sending configuration parameters to nodes within networks to optimize resource allocation and usage across different telecommunication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RF spectrum is allocated to multiple networks simultaneously, then spectrum utilization improves, but interference and service quality deteriorate
Solution Approach 1:
The patent implements dynamic spectrum allocation where network configurations are changed in real-time based on traffic conditions. The source network dynamically switches between providing full service and providing only access to target network resources, allowing spectrum to be reallocated from underutilized networks to congested networks without causing interference, thus improving both spectrum utilization and service quality
Solution Approach 2:
The patent introduces a spectrum broker as an intermediary entity that coordinates between source and target networks. The broker receives configuration parameters from the source network and sends them to target network nodes, managing the spectrum allocation process to ensure seamless handoff and prevent interference, thereby maintaining service quality while enabling efficient spectrum sharing
2Productivity
If spectrum is reallocated dynamically between networks, then resource efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments the spectrum allocation process into distinct functional components: source network identification, configuration parameter generation, spectrum broker coordination, and target network application. This segmentation allows each component to be managed independently, reducing overall system complexity while enabling dynamic resource reallocation
Solution Approach 2:
The patent creates a universal configuration parameter format that can be applied across different network types and technologies. The broker uses standardized procedures to manage spectrum allocation between various networks, reducing complexity by providing a single multi-functional framework rather than separate mechanisms for each network pair
3Speed
If configuration parameters are sent to multiple network nodes, then resource allocation speed improves, but communication overhead increases
Solution Approach 1:
The patent performs preliminary actions by pre-generating configuration parameters at the source network before actual spectrum reallocation is needed. These parameters are ready when traffic conditions change, enabling immediate spectrum switching without extensive real-time communication, thus reducing communication overhead while maintaining fast allocation speed
Solution Approach 2:
The patent implements feedback mechanisms where the broker monitors spectrum utilization and traffic conditions across networks. This feedback allows the system to optimize configuration parameter transmission by sending updates only when necessary, reducing communication overhead while ensuring timely resource reallocation in response to changing conditions

AI summary
A server computing device may be configured to perform dynamic spectrum arbitrage (DSA) operations that include broadcasting a communication message that includes information advertising that a telecommunication resource in a first telecommunication network is available for allocation and use by wireless devices in a second telecommunication network, determining lease criteria parameters of a resource lease associated with the advertised telecommunication resource, determining network capability of the second telecommunication network, selecting one of a DSA Lite network configuration, DSA9 network configuration, and DSAX network configuration based on the determined network capability and determined lease criteria, determining configuration parameters for one or more nodes in each of the first and second telecommunication networks based on the selected network configuration, and sending the determined configuration parameters to components in each of the first and second networks.
