Terminal Configuration Updates Without IMS Service Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G and future communications systems, the configuration update procedure for terminals with IMS-based services causes service interruptions due to signaling connection release procedures.
Innovation Solution
The mobility management network element suspends configuration updates for terminals with critical services, ensuring service continuity by determining the presence of target services and delaying updates until they are completed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the mobility management network element initiates a terminal configuration update procedure, then the configuration update is completed, but the service continuity is interrupted
Solution Approach 1:
The mobility management network element performs preliminary detection to determine whether the terminal has IMS-based services before initiating the configuration update procedure. This preliminary action allows the system to prepare appropriate handling measures in advance, avoiding service interruption by delaying or modifying the configuration update when IMS services are detected.
2Productivity
If the signaling connection release procedure is triggered, then the configuration update procedure is completed, but the IMS-based service is interrupted
Solution Approach 1:
The mobility management network element uses feedback from the terminal's service status information to control the configuration update process. When feedback indicates the presence of IMS-based services, the system adjusts its actions to maintain service continuity while still completing the configuration update, thereby resolving the contradiction between update efficiency and service reliability.

AI summary
This application provides a configuration update method and apparatus. The method includes: if determining that a configuration of a terminal needs to be updated, first determining, by a mobility management network element, whether the terminal has a target service; and if determining that the terminal has the target service, sending, by the mobility management network element, a configuration update message to the terminal, and forgoing, by the mobility management network element, triggering a signaling connection release procedure. This helps avoid interrupting execution of the target service, because the signaling connection release procedure is not triggered.
