Solution Overview

Problem

Existing data rate adaptation mechanisms in server devices are inefficient due to delays in end-to-end measurements and incorrect estimations of available bandwidth, leading to inaccurate adjustments, network congestion, and suboptimal resource utilization.

Innovation Solution

Implementing data rate adaptation based on communications between a radio access network (RAN) and a server device, where the RAN calculates data rate parameters and transmits them to the server, allowing for more accurate adjustments considering various network factors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If end-to-end measurements are used for data rate adaptation, then the server device can adjust data rate based on network conditions, but delays in measurements and changing network conditions cause inaccurate adjustments

Engineering Contradiction:

Improvedata rate adjustment accuracyVSAvoidmeasurement delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The RAN performs preliminary measurements of network conditions (signal quality, interference, loading) before the server device needs to make data rate adjustments. These pre-measured parameters are transmitted to the server device, allowing it to make accurate adjustments without waiting for end-to-end measurement results, thus reducing measurement delay and improving timing accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The RAN acts as an intermediary that performs measurements and provides data rate parameters to the server device. Instead of the server device directly performing end-to-end measurements, the RAN intermediates by measuring local network conditions and transmitting relevant parameters, thereby reducing measurement delay and improving adjustment accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If end-to-end measurements are used for data rate adaptation, then the server device can control data rate, but incorrect estimations of available bandwidth lead to network congestion and suboptimal resource utilization

Engineering Contradiction:

Improvebandwidth estimation accuracyVSAvoidnetwork congestion

Core Design Contradiction:

Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The RAN continuously monitors network conditions including signal quality, interference, and loading, and provides feedback parameters to the server device. This feedback mechanism enables the server device to make accurate bandwidth estimations and data rate adjustments, preventing network congestion and suboptimal resource utilization by basing decisions on real, accurate network state information.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical end-to-end measurement system with a more sophisticated measurement approach using RAN-based measurements. The RAN measures local network conditions (signal quality, interference, loading) and transmits these parameters to the server device, which then calculates available bandwidth more accurately, avoiding the congestion and resource inefficiency caused by incorrect bandwidth estimations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If RAN-based data rate parameters are used, then measurement accuracy and resource utilization improve, but system complexity increases due to additional communication interfaces

Engineering Contradiction:

Improvedata rate parameter accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The RAN performs multiple functions: it serves as the access network for user equipment, performs measurements of network conditions, and provides data rate parameters to the server device. By making the RAN multi-functional, the patent avoids adding separate dedicated measurement and control systems, thereby improving measurement accuracy while limiting the increase in overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

In some implementations, a radio access network (RAN) may obtain data rate information from a device. The device may be associated with an application and the data rate information may be associated with the application. The RAN may determine, based on the data rate information, one or more data rate parameters associated with the application. The one or more data rate parameters may include at least one of one or more radio frequency parameters, one or more network loading parameters, one or more mobility parameters, or an available data rate parameter. The RAN may transmit, to the device, the one or more data rate parameters.
