Adjustable Zone Data Rate Control for LTE Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks face congestion issues when user equipment devices switch from 5G to LTE coverage, leading to network overload due to the larger bandwidth of 5G networks being reduced, which is not effectively managed by existing standards.
Innovation Solution
The implementation of an adjustable zone (AZ) within the network that adjusts data rates for user equipment devices based on current network conditions and services used, utilizing techniques like EN-DC and an Adjustable Zone Manager (AZM) to manage data rates and zone sizes, ensuring optimal network performance by reducing load on LTE networks during congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment devices switch from 5G to LTE coverage, then coverage continuity is maintained, but network congestion occurs due to bandwidth reduction
Solution Approach 1:
The patent implements dynamic data rate adjustment based on device location within adjustable zones. When devices are in the AZ, their data rates are dynamically reduced to prevent LTE congestion while maintaining connectivity. This dynamic control resolves the contradiction by adapting throughput levels to current network conditions rather than using static rate settings.
Solution Approach 2:
The system changes the data rate parameter for devices based on their position relative to the adjustable zone boundaries. By modifying this key parameter dynamically, the system maintains coverage continuity while preventing network overload, thus resolving the contradiction between reliability and productivity.
2Productivity
If data rate is reduced for devices in adjustable zone, then LTE network congestion is prevented, but user experience may deteriorate
Solution Approach 1:
The patent applies local quality by implementing differentiated data rate policies based on device location. Devices within the adjustable zone experience reduced data rates to protect network capacity, while devices outside the zone maintain full data rates. This localized approach prevents congestion in critical areas without broadly degrading user experience across the entire network.
Solution Approach 2:
The adjustable zone acts as an intermediary mechanism between full 5G bandwidth and reduced LTE capacity. By introducing this intermediate state with controlled data rate reduction, the system balances network load management with acceptable user experience, resolving the contradiction between productivity and ease of operation.
3Productivity
If adjustable zone size is increased to keep more devices in 5G footprint, then network congestion is reduced, but coverage area for rate control increases
Solution Approach 1:
The adjustable zone size is made dynamic rather than static. The zone boundaries can be adjusted based on current network conditions, device distribution, and traffic patterns. This allows the system to optimize the balance between load distribution and zone coverage area in real-time, resolving the contradiction between productivity and area.

AI summary
A telecommunications network may adjust service (e.g., data rate) to UE devices within an adjustable zone (AZ) that includes at least two types of coverage (e.g., 4G and 5G), depending on services being utilized by the UE devices and current network conditions of the telecommunications network. When a UE device enters the AZ, the services utilized by the UE device are determined. For instance, if the UE device is moving within the AZ, and the LTE is congested, the data rate for the device may be reduced. If the LTE network is not in a heavy loaded condition and the UE device is utilizing an Enhanced Mobile Broadband (EMBB) service, the AZ can be reduced or disabled. Further, the device data rate can be reduced for different services in the AZ to keep more devices in NR coverage.
