Carrier Aggregation Limiting for High Mobility Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High mobility wireless devices experience delayed carrier aggregation, leading to inefficient resource utilization as they transition between cells, resulting in increased demand on access nodes without the bandwidth benefits of carrier aggregation.
Innovation Solution
A method and system that identify high mobility wireless devices based on the number of carrier aggregation messages and deny carrier aggregation to these devices by comparing their wireless device IDs, thereby managing resource allocation and reducing unnecessary bandwidth provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If carrier aggregation is provided to all wireless devices after entering service area, then bandwidth availability is improved, but resource demand on access node increases for high mobility devices
Solution Approach 1:
The patent applies local quality by differentiating carrier aggregation provisioning based on device mobility characteristics. Instead of uniformly providing carrier aggregation to all devices, the system identifies high mobility devices through monitoring carrier aggregation message frequency and applies different quality levels (carrier aggregation enabled vs. denied) to different device groups, thereby optimizing resource allocation.
Solution Approach 2:
The patent inverts the conventional approach by denying carrier aggregation to high mobility devices rather than providing it to all devices. This inversion is based on the observation that high mobility devices traverse cells quickly and would not benefit significantly from carrier aggregation, while still consuming access node resources. The system identifies these devices through message frequency analysis and applies the opposite treatment (denial) to reduce resource demand.
2Loss of time
If carrier aggregation is provided quickly after device enters service area, then service improvement is achieved, but high mobility devices traverse substantial portion of cell without benefit
Solution Approach 1:
The patent employs feedback mechanisms by monitoring the frequency of carrier aggregation messages from each wireless device. This feedback information is used to identify high mobility devices and adjust carrier aggregation provisioning accordingly. The system continuously gathers data on device behavior and uses this feedback to make informed decisions about resource allocation, preventing wasteful provisioning for devices that will quickly leave the service area.
Solution Approach 2:
The patent changes the parameter of carrier aggregation provisioning from a static, uniform approach to a dynamic, device-specific approach. By monitoring message frequency and identifying high mobility devices, the system adjusts the carrier aggregation parameter (enabled/disabled) based on device characteristics. This parameter change allows the system to optimize the balance between quick service provision and effective utilization by denying carrier aggregation to devices that would not benefit from it.

AI summary
Systems and methods for limiting carrier aggregation for a wireless device are provided. A high mobility wireless device can be identified based on a number of carrier aggregation messages provided for the high mobility wireless device. An access node can receive a wireless device ID associated with the high mobility wireless device. The access node can obtain a wireless device ID from a wireless device being served by the access node. The wireless device ID of the served wireless device is compared with the wireless device ID of the high mobility wireless device. Carrier aggregation is denied based on the comparison.
