Solution Overview

Problem

Current QoS mechanisms in mobile communications cannot satisfy round-trip QoS requirements for certain services, such as interactive services, and fail to meet specific QoS requirements within specific time ranges, as they only manage one-way uplink or downlink transmission.

Innovation Solution

A QoS control method and apparatus that determine uplink and downlink QoS parameters and transmission time windows based on round-trip QoS parameters and transmission time information, enabling dynamic resource allocation for both uplink and downlink transmissions to meet round-trip QoS requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current QoS mechanisms use unchanged QoS parameters during entire transmission process, then one-way QoS requirements can be satisfied, but round-trip QoS requirements cannot be satisfied

Engineering Contradiction:

ImproveQoS requirement satisfactionVSAvoidservice type coverage

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the round-trip QoS parameter into separate uplink and downlink QoS parameters. The network device receives a round-trip QoS parameter and then determines corresponding uplink and downlink QoS parameters separately, allowing independent optimization of each direction to meet round-trip service requirements

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic QoS parameter adjustment by determining uplink and downlink QoS parameters dynamically based on the round-trip QoS parameter and transmission time information, rather than using static unchanged parameters throughout the transmission process

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If QoS parameters are fixed for entire transmission process, then implementation is simple, but time-sensitive service requirements cannot be met

Engineering Contradiction:

ImproveQoS mechanism implementation complexityVSAvoidtime-sensitive service performance

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent performs preliminary determination of uplink and downlink QoS parameters and transmission time windows before actual data transmission. The network device determines these parameters in advance based on round-trip QoS parameters and transmission time information, enabling time-sensitive services to be properly handled

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes QoS parameters dynamically based on transmission time information. Different uplink and downlink QoS parameters are determined for different time windows, allowing the system to adapt to time-sensitive service requirements while maintaining manageable complexity

Inventive Principle:

Principle #35Parameter changes

AI summary

A quality of service (QoS) control method and apparatus are provided. The method includes: a first node receives a first request message sent by a second node, here, the first request message carries at least one of a value of a round-trip QoS parameter or transmission time information; and the first node determines a value of an uplink QoS parameter and a value of a downlink QoS parameter based on the value of the round-trip QoS parameter, and/or determines an uplink transmission time window and a downlink transmission time window based on the transmission time information.
