Dynamic Frequency Band Allocation for Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Base stations face challenges in efficiently allocating user devices to available frequency bands due to limited capacity, device capabilities, and priority levels, leading to potential network congestion as more user devices are subscribed.
Innovation Solution
Implementing a system that allows base stations to dynamically connect user devices to the most suitable frequency band based on available capacity, device multi-band capabilities, and priority levels, enabling efficient allocation and handling of network growth demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a base station uses a single frequency band with finite capacity, then the system is simple to manage, but the network cannot accommodate growing numbers of user devices
Solution Approach 1:
The patent divides the frequency band resources into multiple separate bands (e.g., Band 1, Band 2, Band 3) with different capacity characteristics. Each band can be independently allocated to user devices based on their capabilities and network conditions, allowing the system to serve more devices simultaneously without overloading a single frequency band.
Solution Approach 2:
The patent implements dynamic frequency band allocation where the base station continuously monitors capacity usage and device conditions, then adaptively assigns devices to appropriate frequency bands. This dynamic adjustment allows the system to respond to changing network conditions and accommodate varying numbers of user devices efficiently.
2Reliability
If the base station allocates frequency bands statically, then the allocation process is simple, but network congestion occurs when capacity is exceeded
Solution Approach 1:
The patent implements a feedback mechanism where the base station continuously monitors the capacity usage of each frequency band and the conditions of connected devices. Based on this feedback, the system dynamically adjusts allocations to prevent congestion while maintaining quality of service, balancing reliability and productivity.
Solution Approach 2:
The patent changes the allocation parameters dynamically based on network conditions. When capacity is available, more devices are allocated to maintain high productivity. When capacity approaches limits, allocations are adjusted to maintain quality of service, preventing network congestion through parameter adaptation.
3Adaptability or versatility
If the base station admits all user device requests, then customer satisfaction is high, but frequency band capacity is exceeded leading to degradation
Solution Approach 1:
The patent applies different allocation strategies to different frequency bands and different user devices based on their specific characteristics. Devices are matched to frequency bands where they can operate effectively, and allocation decisions are made locally for each device-request-band combination, maximizing adaptability while preventing overall network congestion.

AI summary
A device is configured to receive a request, from a user device, to connect to a network using a first frequency band. The device is configured to determine that the first frequency band cannot accommodate the user device. The device is configured to determine that the user device can connect to the network using a second frequency band, and connect the user device to the network using the second frequency band rather than the first frequency band.
