Multi-Card Terminal Capability Reporting Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-card terminals with Dual-Tx and/or Dual-Rx capabilities face service interruptions and performance issues due to the need to update capability information by detaching and reattaching from network equipment, leading to service disruptions.
Innovation Solution
A terminal capability reporting method that allows multi-card terminals to proactively report their capabilities to the base station, enabling timely configuration and avoiding service interruptions by transmitting terminal capability change signaling and receiving confirmation before updating SIM card capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-card terminals update capability information by detaching and reattaching from network equipment, then capability information is updated completely, but service interruptions occur
Solution Approach 1:
The terminal proactively reports capability information to the network equipment before service interruptions occur. The capability reporting is triggered by detection of capability changes (such as SIM card status changes) rather than waiting for detachment-reattachment cycles, thus maintaining service continuity while ensuring capability information is updated.
Solution Approach 2:
The network equipment sends capability enquiry signaling to the terminal, and the terminal responds with capability information in real-time. This feedback mechanism allows the network to obtain accurate capability information without requiring terminal detachment, resolving the contradiction between complete capability updates and service continuity.
2Productivity
If multi-card terminals report capability information proactively, then service interruptions are avoided, but signaling overhead increases
Solution Approach 1:
The terminal reports capability information selectively based on specific triggers such as SIM card status changes, rather than reporting all capability information continuously. This targeted approach reduces signaling overhead while maintaining service continuity by reporting only when necessary.
Solution Approach 2:
Instead of continuous capability reporting, the system uses periodic capability enquiry signaling initiated by the network equipment. The terminal responds to these periodic enquiries with updated capability information, reducing overall signaling overhead while ensuring the network has current capability data when needed.
