Direct User-Plane QoS Reporting for Timely Application Adjustment
Solution Overview
Problem
The conventional method for reporting QoS requirements in 5G communication networks involves a long reporting path, leading to reduced timeliness and inadequate adjustment of service data flows, particularly for applications with high time sensitivity.
Innovation Solution
A user plane network element directly reports indication information to an application function network element, bypassing multiple core network elements, thereby shortening the reporting path and improving timeliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If indication information is reported sequentially through multiple core network elements (AMF, SMF, PCF, NEF), then the reporting path is established according to the conventional architecture, but the reporting path becomes long and timeliness of reporting is reduced
Solution Approach 1:
The patent extracts the indication information reporting function from the conventional sequential path (AMF→SMF→PCF→NEF→AF) and establishes a direct reporting link from the access network element to the AF network element. This extraction eliminates unnecessary intermediate nodes in the reporting path, directly resolving the contradiction between maintaining reliable reporting path establishment and improving reporting timeliness.
Solution Approach 2:
The patent introduces a new dimension in the reporting architecture by enabling parallel reporting paths: the traditional sequential path through core network elements and a new direct path from access network element to AF network element. This dimensional change allows the system to bypass multiple intermediate nodes while maintaining architectural reliability, thus improving reporting timeliness without compromising the established reporting mechanism.
2Device complexity
If the reporting path includes multiple core network elements, then the conventional architecture is maintained, but the AF network element cannot adjust service data flow in a timely manner
Solution Approach 1:
The patent extracts the critical indication information (QoS flow satisfaction status) from the complex sequential reporting chain and delivers it directly to the AF network element. This extraction enables the AF element to immediately adjust service data flow based on real-time QoS status, significantly improving adjustment speed while maintaining the overall architectural structure through complementary use of both reporting paths.
3Reliability
If indication information traverses multiple network elements, then the conventional signaling path is followed, but timeliness for high time-sensitive applications is insufficient
Solution Approach 1:
The patent introduces a direct signaling dimension between access network elements and AF network elements, parallel to the conventional multi-hop signaling path. This new dimension provides a shortened information transmission path for QoS indication information, enabling faster response for high time-sensitive applications while the conventional path remains available for other signaling purposes, thus maintaining overall system reliability.

AI summary
Embodiments of this application provide a reporting information sending method, an apparatus, and a system, and relate to the field of communication technologies, to resolve technical problems in a conventional technology that a path used by an access network element to report indication information used to indicate whether a QoS requirement of a QoS flow can be satisfied is long, timeliness is poor, it is unfavorable for an application function network element to adjust a service data flow of an application in a timely manner, and a QoS requirement of the application cannot be satisfied. The method includes: A user plane network element receives, from a first access network element, a first message including an identifier of a first quality of service flow QoS flow and first indication information, where the first indication information is used to indicate whether a quality of service QoS requirement of the first QoS flow can be satisfied; and sends first reporting information including second indication information to an application function network element based on the first message, where the second indication information is used to indicate whether a QoS requirement of a service data flow of an application can be satisfied, and the first QoS flow is used to transmit the service data flow of the application corresponding to the application function network element.
