Solution Overview

Problem

The quality of service (QoS) for time-sensitive communication services can degrade due to changes in local settings of terminal devices, causing the core network's configured QoS rules to no longer meet the service requirements.

Innovation Solution

A terminal device determines and sends first service information to the core network, enabling the core network to update policies accordingly, using modules within the device to process and transmit this information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the core network configures QoS rules based on initial service features, then the service quality is initially ensured, but when local settings change the service features, the QoS rules become invalid and service quality degrades

Engineering Contradiction:
Improveservice qualityVSAvoidadaptability to local settings changes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The terminal device periodically reports its local settings (such as application information, network preferences, or configuration changes) to the core network. This feedback mechanism enables the core network to detect changes in service features and update QoS rules accordingly, ensuring continuous service quality adaptation without requiring constant manual reconfiguration.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The QoS rules are transformed from static configurations to dynamic parameters that can automatically adapt to changing local settings. The core network dynamically adjusts QoS parameters (such as priority, bandwidth, or latency requirements) based on real-time or periodic updates from the terminal device, allowing the system to respond flexibly to varying service requirements.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the terminal device provides detailed service feature information to the core network, then the QoS rules can be accurately configured, but the information transmission and processing complexity increases

Engineering Contradiction:
Improveservice feature accuracyVSAvoidinformation processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The terminal device identifies and reports only the specific local settings that are relevant to service feature changes (such as active applications, selected network modes, or local configuration parameters). This selective reporting approach provides the core network with precise information about actual service requirements while avoiding the transmission and processing of unnecessary detailed information, thus balancing accuracy with complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The terminal device and core network establish predefined mapping relationships or templates for service feature information before actual communication occurs. These pre-configured frameworks guide the terminal in reporting only the necessary feature parameters, reducing the complexity of information processing while maintaining measurement precision for QoS rule configuration.

Inventive Principle:
Principle #10Preliminary action

AI summary

This application provides a communication method, apparatus, and system, to enhance quality of service of a service. The method includes: A terminal device determines first service information, where the first service information is used to describe a feature of a service of the terminal device; and the terminal device sends the first service information to a core network, where the first service information is used by the core network to determine a policy corresponding to the service. In this solution, the terminal device may provide the first service information for the core network, so that the core network can determine the policy for the terminal device based on the first service information. In this way, transmission quality of a data packet of a service of the terminal device is controlled.
