Multi-SIM Paging Control Using Service Type in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM terminals face difficulties in smoothly performing paging reception and idle-mode operations on other networks due to limitations in current communication systems, particularly when one SIM is in connected mode and the other is in idle mode.
Innovation Solution
Incorporating service type information in paging messages to enable multi-SIM terminals to determine whether to release or maintain connections based on the received paging message, allowing seamless transitions between networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-SIM terminal maintains connected mode on one network, then data transmission reliability is improved, but the ability to perform paging reception and idle-mode operations on other networks deteriorates
Solution Approach 1:
The terminal dynamically transitions between connected mode and idle mode based on service requirements. When a paging message indicates a specific service, the terminal releases the connected mode to perform idle-mode operations on the other network, and can re-establish connection when needed. This dynamic state adjustment resolves the contradiction between maintaining reliable data transmission and enabling paging reception on multiple networks.
Solution Approach 2:
The system changes the operational state parameters of the terminal (from connected mode to idle mode) based on the service type indicated in the paging message. This parameter change allows the terminal to switch between different operational states to satisfy different service requirements, thereby resolving the contradiction between data transmission reliability and multi-network adaptability.
2Adaptability or versatility
If a multi-SIM terminal releases connected mode to perform idle-mode operations on another network, then paging reception capability is improved, but data transmission continuity deteriorates
Solution Approach 1:
The terminal receives and evaluates the paging message in advance, which includes service type information. Based on this preliminary information, the terminal determines whether releasing connected mode is necessary before actually doing so. This preliminary assessment allows the terminal to maintain data transmission continuity by only releasing connection when truly necessary for specific services.
Solution Approach 2:
The system uses feedback from the paging message (service type information) to determine whether to release connected mode. This feedback mechanism ensures that the terminal only transitions to idle mode when the service requirement justifies it, thereby maintaining data transmission continuity while enabling necessary paging reception operations.
3Productivity
If service type information is included in paging messages, then connection management efficiency is improved, but message complexity increases
Solution Approach 1:
The service type information is merged into the existing paging message structure rather than being transmitted as a separate message. This combining approach improves connection management efficiency by providing necessary service information in the already-transmitted paging message, while minimizing the increase in message complexity by reusing the existing message framework.
Solution Approach 2:
The paging message is designed to serve multiple functions: it provides both the standard paging notification and additional service type information. This multi-functionality improves connection management efficiency by consolidating multiple information types into a single message, thereby reducing the need for additional separate signaling messages.
