Dynamic UE Redirection to Standalone 5G for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G and LTE capable user equipment (UE), the simultaneous connection to both 5G and LTE antennas leads to higher power consumption, reducing battery life due to the need to communicate with multiple network nodes, which is not optimally managed by current systems.
Innovation Solution
A system dynamically re-directs a dual configuration UE from a non-standalone EN-DC node to a standalone 5G node based on buffer status reports, optimizing resource allocation and extending battery life by reducing the need for simultaneous communication with both 5G and LTE antennas.

Engineering Contradiction Analysis
1Reliability
If a UE automatically attaches to both LTE and 5G carriers for dual connectivity, then network coverage and service reliability are improved, but power consumption increases and battery life deteriorates
Solution Approach 1:
The patent implements dynamic connection management where the UE transitions between connected and idle states based on data activity. During data transmission, the UE maintains connections to both LTE and 5G nodes for reliable dual connectivity. When data activity ceases, the UE releases the 5G connection and enters idle state, significantly reducing power consumption while maintaining service reliability when needed.
Solution Approach 2:
The system employs periodic buffer status reporting and data activity monitoring to dynamically adjust connection states. The network node periodically checks buffer status and triggers connection state transitions based on detected data activity patterns, enabling the UE to alternate between high-reliability dual-connection mode and low-power single-connection mode.
2Productivity
If a UE maintains simultaneous connections to both 5G and LTE nodes, then data transmission capability is improved, but device complexity and resource allocation difficulty increase
Solution Approach 1:
The patent segments the connection management into distinct phases: active transmission phase where dual connections are maintained for high data throughput, and idle phase where connections are released to reduce complexity. This temporal segmentation allows the system to achieve high productivity when needed while minimizing device complexity during low-activity periods.
Solution Approach 2:
The system extracts and releases the 5G connection from the dual-connection configuration when data activity is not detected. By taking out the unnecessary 5G connection during idle periods, the system reduces connection management complexity and resource allocation overhead while preserving the capability to re-establish it when data transmission is required.

AI summary
Systems and methods are provided for dynamically re-directing a wireless communication deice to improve spectral efficiency, load balancing, and battery life. The system comprises at least a first node and a second node that are each configured to communicate with one or more devices in a service area. The system receives an indication that a first device is connected to the first node and then receives a real-time buffer status report for the first UE which indicates how much data is being transmitted by the device. Based on determining that the real-time buffer status of the device is below a predetermined buffer status report threshold, the system dynamically re-directs the device to disconnect from the first node and connect to the second node.
