MT-SDT Access Reason Signaling for UE Connection Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The network lacks information on the reason why a user equipment (UE) fails to initiate a mobile terminated small data transmission (MT-SDT) procedure, which hinders optimization of communication efficiency.
Innovation Solution
A terminal device receives an indication message from a network device to initiate MT-SDT and indicates the access reason of the connection attempt based on its operation status, allowing the network device to understand the failure reason and optimize communication accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network device does not obtain access reason information from the terminal device, then the signaling overhead is reduced, but the network device cannot prioritize connection attempts or optimize communication efficiency
Solution Approach 1:
The patent extracts only the necessary access reason information from the terminal device's operation status and transmits it to the network device. This selective extraction allows the network to obtain critical information for prioritization without requiring complete operational details, thus improving communication efficiency while minimizing information loss.
Solution Approach 2:
The terminal device provides feedback to the network device about its operation status and access reasons. This feedback mechanism enables the network to understand why connection attempts are made, allowing for optimized resource allocation and prioritization of urgent communications.
2Productivity
If the terminal device indicates detailed operation status to the network device, then the network can optimize communication better, but the signaling overhead and complexity increase
Solution Approach 1:
The patent applies extraction by selecting only the relevant access reason information from the terminal device's complete operation status. Instead of transmitting all operational details, only the essential elements needed for network optimization are communicated, reducing signaling complexity while maintaining optimization capability.
Solution Approach 2:
The patent applies local quality by providing different levels of information detail based on the specific communication context. The terminal device indicates access reasons selectively, offering more detailed operation status only when necessary for network optimization, thereby balancing communication optimization with signaling complexity management.
