RAN Channel Condition Predictive Model for Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content providers face challenges in efficiently delivering content to users with varying wireless connectivity, as existing methods like speed tests and Slow Start TCP algorithms are inefficient and result in delayed content delivery and suboptimal resource utilization in wireless networks.
Innovation Solution
A predictive model is used to estimate channel conditions, allowing content providers to select the appropriate content version and transmission methodology, such as the Bottleneck Bandwidth and Round-trip propagation time (BBR) algorithm, for enhanced user experience and resource management in wireless networks.

1Productivity
If speed tests and Slow Start TCP algorithms are used to determine content delivery capability, then content can be delivered to users with varying wireless connectivity, but content delivery is delayed and resource utilization in wireless networks is suboptimal
Solution Approach 1:
The system performs preliminary channel condition assessments and pre-determines optimal content versions before actual content delivery requests. By evaluating wireless channel conditions in advance and caching appropriate content versions, the system eliminates the need for slow speed tests and progressive transmission algorithms, directly delivering pre-selected content that matches current channel conditions.
Solution Approach 2:
The system continuously monitors wireless channel conditions and uses this feedback to dynamically select and deliver appropriate content versions. Real-time channel quality indicators feed into the content selection mechanism, enabling the system to adapt to changing wireless conditions without requiring slow trial-and-error transmission approaches.

If speed tests and Slow Start TCP algorithms are used to determine content delivery capability, then content can be delivered to users with varying wireless connectivity, but resource utilization in wireless networks is suboptimal
Solution Approach 1:
The system pre-evaluates channel conditions and pre-selects optimal content versions before actual delivery, caching them at strategic points in the network. This preliminary preparation eliminates the need for progressive transmission attempts that waste network resources on unsuitable content versions, directly delivering optimally-matched content from the first transmission attempt.
Solution Approach 2:
The system continuously monitors wireless channel conditions and uses this feedback to intelligently select content versions that match current network capabilities. This feedback-driven selection prevents wasteful transmission of high-bandwidth content versions when channel conditions are poor, optimizing overall network resource utilization.

AI summary
A system described herein may provide a technique for the modeling of channel condition information, associated with a base station of a radio access network (“RAN”) associated with a wireless network, over time. The model may be used to determine, estimate, or predict channel information associated with the base station at a given time, such as a time corresponding to a request for content (e.g., streaming content). The channel condition information corresponding to this time, as determined based on the model, may be used to select a particular version of the content to provide in response to the request. By virtue of receiving this information, the content provider may forgo performing a speed test, a ramp up transmission scheme, and/or other technique that may otherwise used to select the version of the content to provide in response to the request.
