Carrier Aggregation Control Using Core-Network Traffic Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carrier aggregation in wireless communication systems is controlled by connection nodes lacking insight into data communication patterns, leading to inefficient bandwidth allocation based on instantaneous metrics.
Innovation Solution
A core network component, such as a packet data network gateway, analyzes data communication patterns and predicts bandwidth requirements to generate carrier aggregation triggers, controlling carrier aggregation based on anticipated data needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If carrier aggregation is controlled by connection nodes based on instantaneous metrics, then the system can maintain simple control architecture, but bandwidth allocation efficiency deteriorates due to lack of insight into data communication patterns
Solution Approach 1:
A core network component is introduced as an intermediary between the data communication system and the carrier aggregation control mechanism. This intermediary analyzes data communication patterns and generates carrier aggregation triggers, enabling efficient bandwidth allocation without requiring complex modifications to the connection nodes. The intermediary mediates between the need for simple control architecture and the need for pattern-aware bandwidth management.
2Productivity
If carrier aggregation is activated for all data communications, then throughput is maximized for high-bandwidth applications, but resource waste increases for applications requiring limited data transfer
Solution Approach 1:
The system performs preliminary analysis of data communication patterns before activating carrier aggregation. By examining communication patterns in advance and generating triggers based on predicted bandwidth requirements, the system activates carrier aggregation only when and where it is truly needed. This preliminary action prevents resource waste on applications that don't require high bandwidth while ensuring adequate throughput for applications that do.
3Ease of operation
If carrier aggregation is controlled without analyzing data communication patterns, then the control mechanism remains simple and responsive, but bandwidth allocation accuracy deteriorates
Solution Approach 1:
The pattern analysis function is extracted from the connection nodes and placed in a dedicated core network component. This extraction maintains the simplicity and responsiveness of the connection node control mechanism while improving bandwidth allocation accuracy through specialized pattern analysis. The core network component handles the complex analysis separately, allowing connection nodes to remain simple and responsive.

AI summary
Systems and methods for controlling carrier aggregation (CA) are disclosed. The method includes determining a communication characteristic describing data communicated between, e.g., user equipment (UE) and a communication endpoint. The communication characteristic is used to generate a CA trigger that controls at a communication node a number or assignment of component carriers or communication slots used to communicate the data to/from the UE.
