Solution Overview

Problem

Current terminals are unable to report data related to wireless communication, such as location and data usage, directly to the core network, and can only report application-related data to OTT servers.

Innovation Solution

A method and apparatus that enable a terminal to report UE-related information, such as URSP, WLANSP, and UE status, to a control plane entity through a UPF entity, which then forwards it to a SMF entity and ultimately to a PCF entity, using identifiers in GTP and PDCP headers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the terminal reports application-related data to OTT servers, then the terminal can report data, but the core network cannot obtain wireless communication data such as location and data usage

Engineering Contradiction:
Improvewireless communication dataVSAvoiddata reporting architecture
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces the UPF (User Plane Function) as an intermediary component between the terminal and the core network. The UPF receives user plane data from the terminal, extracts UE-related information, and forwards it to the SMF (Session Management Function) in the core network. This intermediary approach enables the core network to obtain wireless communication data without requiring direct terminal-to-core-network reporting mechanisms, thus resolving the information loss problem while maintaining architectural clarity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the terminal can only report to OTT servers, then the reporting mechanism is simple, but comprehensive data reporting to the core network is not achieved

Engineering Contradiction:
ImproveUE-related informationVSAvoiddata reporting configuration
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent implements preliminary action by pre-configuring the UPF with identification rules for UE-related information and pre-establishing the data extraction and forwarding mechanisms. The UPF is预先 configured to recognize specific identifiers (such as 5GI, 5GS-Tunnel-ID, or PDU Session ID) and automatically extract relevant UE information without requiring real-time complex processing. This preliminary setup enables comprehensive data reporting to be achieved with minimal operational complexity during actual data transmission.

AI summary

The present invention discloses a method and an apparatus for reporting information by a terminal, and a computer storage medium. The method includes: sending, by the terminal, a first message to a RAN, the first message including a first identifier and UE related information, so as to send a second message to a UPF through the RAN, the second message including the first identifier and the UE related information, and to send the UE related information to an SMF through the UPF after identifying the first identifier in the second message through the UPF, and then to send the UE related information to a PCF through the SMF.
