Dynamic Buffer Modification for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face challenges in providing high-quality service to increasing numbers of devices due to inadequate load balancing and resource utilization, particularly for applications requiring high throughput, low latency, or high quality of service, leading to unsatisfactory service and resource wastage with the excessive use of newer radio access technologies.
Innovation Solution
Dynamic buffer modification based on application categories, where the buffer size is reduced for devices requiring high throughput or low latency to trigger carrier aggregation, and increased for those not requiring it, optimizing network load and resource utilization by identifying application categories through indicators and Quality of Service Class Identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carrier aggregation is implemented for all devices to improve service quality, then high throughput and low latency are achieved, but network resources are wasted on devices with lower requirements
Solution Approach 1:
The patent applies local quality by differentiating buffer size adjustments based on application category. High-priority applications (video streaming, gaming, VoIP) receive reduced buffer sizes to trigger CA, while low-priority applications (email, messaging, web browsing) maintain standard buffer sizes. This selective approach ensures network resources are allocated precisely where needed rather than uniformly across all devices.
Solution Approach 2:
The patent changes the buffer size parameter dynamically based on application category identification. When a device runs high-priority applications, the buffer size is reduced to a threshold value that triggers CA mode. This parameter modification enables the system to adapt network resource allocation to actual service requirements, improving throughput for critical applications while conserving resources for less demanding ones.
2Productivity
If newer radio access technologies are over-utilized to provide additional resources, then capacity and speed are improved, but existing carriers become under-utilized resulting in resource wastage
Solution Approach 1:
The patent implements dynamics by making buffer size adjustable rather than fixed. The buffer size is modified in real-time based on the device's application category and current network conditions. This dynamic adjustment allows the system to flexibly allocate resources between different carriers, ensuring that newer high-capacity RATs are utilized only when necessary while maintaining efficient use of existing carriers.
3Power
If buffer size is reduced to trigger carrier aggregation, then high throughput applications are served better, but devices running average throughput applications may experience unnecessary CA activation
Solution Approach 1:
The patent segments applications into distinct categories (high-priority and low-priority) and applies different buffer size strategies to each segment. High-priority applications such as video streaming, online gaming, and VoIP receive reduced buffer sizes to enable CA mode, while low-priority applications like email, instant messaging, and web browsing maintain standard buffer sizes. This segmentation prevents unnecessary CA activation for applications that do not require high throughput.
Solution Approach 2:
The patent applies local quality by customizing buffer size parameters according to specific application requirements. Each application category receives a tailored buffer size configuration that matches its performance needs, ensuring that CA is triggered only when genuinely necessary for high-priority applications while avoiding unnecessary resource consumption for low-priority applications.

AI summary
A method is provided for dynamically modifying a buffer in a network deploying multiple carriers, wherein multiple wireless devices communicate over the network. The wireless devices run applications, each application belonging to an application category. The method includes identifying the application category for a selected wireless device communicating over the network, wherein a first application category requires at least one of high throughput and low latency. The method additionally includes reducing a size of the buffer when the application category is the first application category, thereby initiating carrier aggregation for the selected wireless device.
