Exposure Function Node RDS Capability Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Application function nodes may not obtain timely information about the network's current capability to support Reliable Data Service (RDS), leading to potential data transmissions with improper configurations.
Innovation Solution
A method implemented at an exposure function node to obtain the RDS configuration of a terminal device, determine the network's RDS capability, and send a message to the application function node if the RDS capability changes, ensuring the application function node is informed about the network's RDS configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the application function node transmits data without obtaining timely RDS capability information, then data transmission can proceed, but data integrity and reliability deteriorate due to improper configuration
Solution Approach 1:
The exposure function node performs preliminary determination of the network's RDS capability and sends notification messages to the application function node before data transmission begins. This ensures the application function node has the necessary RDS configuration information in advance, allowing it to configure data transmission properly and avoid reliability issues while maintaining transmission efficiency.
Solution Approach 2:
The exposure function node establishes a feedback mechanism by monitoring changes in the network's RDS capability and actively notifying the application function node when changes occur. This feedback loop ensures the application function node always has up-to-date RDS configuration information, maintaining data integrity without requiring continuous polling that would reduce productivity.
2Loss of information
If the exposure function node continuously monitors and notifies RDS capability changes, then information accuracy improves, but system complexity and signaling overhead increase
Solution Approach 1:
Instead of continuous monitoring, the exposure function node employs periodic action by only actively notifying the application function node when the RDS capability actually changes. The node maintains the current RDS capability information and sends update notifications only at the moments when changes occur, thereby maintaining information accuracy while minimizing signaling overhead and system complexity.
Solution Approach 2:
The exposure function node extracts and sends only the essential RDS capability information to the application function node through targeted notification messages. By extracting only the necessary capability indicators rather than transmitting complete configuration sets continuously, the system maintains information accuracy while reducing message complexity and processing overhead.

AI summary
The present disclosure provides a method and an apparatus for notifying an application function node about a reliable data service (RDS) configuration of a network. The method implemented at an exposure function node includes: obtaining an RDS configuration of a terminal device; determining an RDS capability of a network; and sending a message including information about the RDS capability of the network to the application function node, if the RDS capability of the network is changed. The RDS capability of the network indicates whether the network supports the RDS. The method implemented at an application function node includes: receiving, from an exposure function node, a message including information about the RDS of the network, if the RDS capability of the network is changed. Data transmissions of the application function node with improper configuration may be avoided.
