Solution Overview

Problem

Existing IMS registration methods in 5G networks result in unnecessary execution processes and waste of communication resources due to the user equipment triggering IMS registration processes even when the IMS service is not activated.

Innovation Solution

An IMS registration method that sends a request to the core network to detect whether the electronic terminal activates the IMS service, and based on the detection result, determines whether to trigger the IMS registration process, thereby avoiding unnecessary processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user equipment triggers IMS registration process automatically, then the IMS service can be accessed when activated, but unnecessary registration processes occur when IMS service is not activated, wasting communication resources

Engineering Contradiction:
ImproveIMS service accessibilityVSAvoidcommunication resources
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by having the user equipment obtain IMS service activation status information before triggering the IMS registration process. The terminal checks whether the IMS service is activated in advance, and only initiates registration when the service is actually activated. This prevents unnecessary registration processes and saves communication resources while ensuring reliable IMS service access when needed.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the IMS registration process is always executed, then IMS service is guaranteed when activated, but unnecessary processes are executed when not activated, reducing system efficiency

Engineering Contradiction:
ImproveIMS service availabilityVSAvoidsystem efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements feedback by having the user equipment obtain and respond to IMS service activation status information. The terminal receives feedback about whether the IMS service is activated and adjusts its behavior accordingly - triggering registration only when activated, and skipping it when not activated. This feedback mechanism ensures IMS service availability when needed while improving system efficiency by avoiding unnecessary processes.

Principle #23Feedback

AI summary

Disclosed in the present application are an IMS registration method, a storage medium, and an electronic terminal. The method comprises: sending an IMS registration request to a core network, so that the core network detects, according to the IMS registration request, whether an electronic terminal has activated an IMS service, and feeds back a detection result; receiving the detection result fed back by the core network; and determining, according to the detection result, whether to trigger an IMS registration process.
