Relay Node Frequency Band Allocation for Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication systems face efficiency issues due to excessive load on certain network portions, particularly during high data traffic, which can lead to suboptimal service quality.
Innovation Solution
Monitoring the utilization of a first frequency band for communication between a relay node and wireless devices, determining if it meets a utilization criteria, and then selecting and allocating either a second or third frequency band for communication to balance the load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single frequency band is used for communication between relay node and wireless devices, then the system structure is simple, but the network experiences excessive load during high data traffic
Solution Approach 1:
The system dynamically changes the frequency parameter by switching between a first frequency band and a second frequency band based on load conditions. When the first frequency band becomes congested, the relay node switches to the second frequency band, thereby adjusting the operational parameter to maintain service quality without increasing structural complexity
2Reliability
If frequency band switching is implemented to balance load, then service quality is enhanced, but the system complexity increases
Solution Approach 1:
The frequency band allocation is made dynamic rather than static. The relay node continuously monitors load conditions and adapts its frequency band selection in real-time, transitioning from a fixed frequency configuration to a dynamic one that automatically adjusts to traffic conditions, thereby enhancing service quality with minimal additional complexity
3Productivity
If multiple frequency bands are allocated for different communication purposes, then load balancing is achieved, but the spectrum management complexity increases
Solution Approach 1:
The available spectrum is segmented into distinct frequency bands (first frequency band and second frequency band) with specific allocation purposes. The first frequency band is used for normal operations while the second serves as a backup or supplementary resource, creating a segmented structure that simplifies management by clearly defining the function and usage conditions of each band

AI summary
Systems and methods are described for managing communications of an access node and a relay node. A utilization of a first frequency band that is used for communication between a relay node and wireless devices may be monitored. The relay node may also communicate with an access node to connect to a network. It may be determined that the monitored utilization meets a utilization criteria. One of a second frequency band and a third frequency band may be selected for the relay node based on the determination that the monitored utilization meets the utilization criteria. The selected frequency band may be allocated for communication between the relay node and wireless devices.
