Mobility Load Balancer Gateway Dynamic Spectrum Arbitrage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for radio frequency spectrum due to the rise in wireless communication devices leads to issues like dropped calls and slow internet access, as existing networks become overwhelmed, while emergency services' RF bands remain underutilized, necessitating a dynamic allocation of telecommunication resources.
Innovation Solution
A dynamic spectrum arbitrage method that involves determining the current capacity of Mobility Management Entity (MME) components across networks, selecting the most suitable MME to manage mobility operations, and reallocating resources to balance network traffic and ensure efficient use of underutilized spectrum, particularly during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless devices increase access to networks, then network coverage and service availability improve, but network congestion increases causing dropped calls and slow internet access
Solution Approach 1:
The patent implements dynamic spectrum allocation where the network dynamically adjusts spectrum resources based on real-time traffic conditions and device requirements. The system continuously monitors network state and reconfigures spectrum assignments to maintain call quality while supporting increased device access, transforming static spectrum allocation into a dynamic adaptive system.
Solution Approach 2:
The system changes key parameters including spectrum bandwidth allocation, modulation schemes, and power levels based on network conditions. By adjusting these parameters dynamically, the network can accommodate more devices while maintaining reliable communication, resolving the contradiction between coverage expansion and call quality preservation.
2Reliability
If RF spectrum is allocated to emergency services, then emergency communication capability improves, but spectrum utilization efficiency decreases due to non-continuous employment
Solution Approach 1:
The patent enables the same RF spectrum to serve multiple functions and multiple networks. Emergency services spectrum is allocated dynamically, allowing it to be used by emergency services when needed and by commercial networks during non-emergency periods. This multi-functional approach ensures reliable emergency communication while maximizing spectrum utilization efficiency.
Solution Approach 2:
The system implements dynamic spectrum sharing where spectrum allocation to emergency services is not fixed but adjusts based on actual emergency needs. During emergencies, spectrum is automatically allocated to emergency services; during normal conditions, it can be reallocated to commercial networks, transforming static dedicated allocation into dynamic shared access.
3Productivity
If more spectrum is allocated to commercial networks, then network capacity improves, but emergency services spectrum availability decreases
Solution Approach 1:
The patent implements dynamic spectrum allocation where the boundary between commercial and emergency spectrum is flexible rather than fixed. The system continuously monitors emergency service requirements and automatically adjusts spectrum allocation, allowing commercial networks to utilize emergency spectrum during non-emergency periods while ensuring immediate availability when emergencies occur, thus increasing overall network capacity without compromising emergency service reliability.
Solution Approach 2:
The system changes spectrum allocation parameters dynamically based on detected emergency conditions. When emergencies are detected, the network reconfigures spectrum assignments to prioritize emergency services; during normal operations, spectrum is allocated to maximize commercial network capacity. This parameter adjustment resolves the contradiction between capacity and emergency availability.

AI summary
A dynamic spectrum arbitrage (DSA) system includes a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources (e.g., spectrum resources) across different networks. The DSC component may include wired or wireless connections to a mobility load balancer gateway (MLB gateway) component that is coupled to eNodeBs, a mobility management entity (MME), and various other network components. The MLB gateway may be configured to serve/operate as a gateway that continuously, repeatedly, or dynamically identifies, selects, and assigns an MME to a wireless device and performs various other mobility management operations to coordinate the handling (e.g., handoffs, hand-ins, backoff, etc.) of the wireless devices as it is moved within and in-between networks.
