Carrier-Initiated Traffic Tuning via TLS Subscription Extensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current throttling techniques in mobile carrier networks are inefficient, leading to unnecessary data packet transmission, prolonged download times, and increased network costs, as they indirectly control video resolution by limiting bandwidth, which can result in suboptimal use of network resources and battery drain in user equipment.
Innovation Solution
Implementing a cooperative system between mobile carriers and content providers to adjust video resolution based on subscriber parameters through dedicated subscription parameter extensions in TLS messages, allowing for real-time optimization of data flows without relying solely on bandwidth throttling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If bandwidth throttling is used to control video resolution, then network capacity usage is reduced, but data transmission time increases and network efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by inserting subscription parameter extensions into TLS handshake messages before video data transmission begins. This allows the content provider to be informed of the subscriber's data cap status in advance, enabling proactive adjustment of video resolution and data transmission rate before the actual video stream starts, thus preventing excessive data consumption while maintaining efficient transmission
Solution Approach 2:
The patent implements feedback by having the content provider monitor data transmission against the subscriber's data cap parameters communicated through the TLS extension. The system continuously compares actual data usage with the subscribed limit and dynamically adjusts video resolution and transmission rate in real-time, creating a closed-loop control that optimizes both data volume reduction and transmission efficiency
2Productivity
If bandwidth throttling is applied to manage network resources, then network capacity is preserved, but network cost increases due to inefficient resource utilization
Solution Approach 1:
The patent applies self-service by enabling the content provider to autonomously manage data transmission based on subscriber parameters. The content provider's system automatically receives subscription parameter extensions, interprets data cap limits, and self-regulates video resolution and transmission rates without requiring carrier intervention or complex carrier-managed throttling infrastructure, thereby improving network efficiency and reducing operational costs
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting video resolution, bitrate, and transmission rate based on the subscription parameters communicated through TLS extensions. Instead of uniform bandwidth throttling, the system modifies multiple transmission parameters (resolution, frame rate, bitrate) to optimize data efficiency, improving network productivity while reducing the energy cost associated with inefficient throttling mechanisms
3Ease of operation
If indirect bandwidth limiting is used to control video quality, then implementation is simple, but video quality optimization is suboptimal
Solution Approach 1:
The patent introduces an intermediary mechanism - the dedicated subscription parameter extension in the TLS handshake - that carries precise subscriber data cap information from the carrier to the content provider. This intermediary structure maintains implementation simplicity by using existing TLS protocols while enabling precise video quality control through structured parameter communication that includes data caps, resolution preferences, and transmission constraints
Solution Approach 2:
The patent applies dynamics by transitioning from static bandwidth throttling to dynamic video quality optimization. The system continuously adapts video resolution, bitrate, and transmission parameters based on real-time monitoring of data consumption against subscribed limits, allowing precise video quality control that responds to changing conditions while maintaining ease of operation through automated parameter adjustment
Data Source
AI summary
A network device for a mobile carrier network sends, to a third-party content platform, a client message including a first dedicated subscription parameter extension. The first dedicated subscription parameter extension indicates one or more subscription parameters for a data flow between a user equipment (UE) device that originated the client message and the third-party content platform. The network device receives, from the third-party content platform, a server message including a second dedicated subscription parameter extension. The second dedicated subscription parameter extension confirms the third-party content platform will abide by the one or more subscription parameters. The network device generates, based on the one or more subscription parameters, a policy enforcement rule for the data flow that relies, at least in part, on cooperation of the third-party content platform.
