SDT Service Control via Priority Configuration and Scheduling Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, small data transmission (SDT) services often conflict with paging services, leading to interruptions and data loss.
Innovation Solution
A method and apparatus for controlling services, where user equipment (UE) obtains priority configuration information from a base station to determine whether to continue SDT based on scheduling indications, ensuring higher-priority services are maintained by prioritizing SDT over paging services when conflicts arise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE performs SDT service during initial access, then data transmission efficiency is improved, but the SDT service conflicts with paging service causing interruptions and data loss
Solution Approach 1:
The base station performs preliminary action by sending priority configuration information to the UE before the SDT service executes, enabling the UE to prepare for potential conflicts. The base station also sends scheduling indication information in advance to indicate when paging service needs to be performed, allowing the UE to preemptively adjust its SDT service execution accordingly.
Solution Approach 2:
The patent applies dynamics by making the service execution flexible rather than rigid. The UE dynamically adjusts its SDT service execution based on real-time priority configuration information and scheduling indication from the base station. When conflicts are detected, the UE can dynamically interrupt or pause SDT service to perform paging service, and resume SDT service after paging is completed, thus adapting to changing service requirements.
2Reliability
If the SDT service is interrupted or abandoned to resolve conflict with paging service, then service conflict is resolved, but information data in the SDT service easily loses
Solution Approach 1:
The base station provides feedback through priority configuration information and scheduling indication to the UE. The priority configuration information continuously updates the UE about the relative priorities of SDT and paging services. The scheduling indication provides specific timing information when paging service must be performed. This feedback mechanism enables the UE to make informed decisions about when to interrupt SDT service for paging, ensuring that data loss is minimized by only interrupting when necessary and for limited durations.
Solution Approach 2:
The base station sends scheduling indication information in advance before the actual conflict occurs. This preliminary action allows the UE to prepare for the upcoming paging service requirement by pausing or adjusting its SDT service execution beforehand. By knowing the timing of the paging service requirement in advance, the UE can efficiently resume the SDT service after paging without losing data, as the interruption duration is minimized and controlled.
3Productivity
If the UE continuously performs SDT service without considering paging service, then data transmission efficiency is maintained, but service conflict with paging service increases
Solution Approach 1:
The base station continuously provides feedback through priority configuration information that reflects the current state of service priorities. This feedback mechanism enables the UE to monitor the service environment and adjust its SDT service execution accordingly. When the base station detects that paging service is needed or has high priority, it updates the priority configuration information or sends scheduling indication, causing the UE to reduce or pause SDT service execution to avoid conflicts.
Solution Approach 2:
The patent implements dynamics by making the SDT service execution adaptive rather than continuous and rigid. The UE dynamically adjusts its data transmission behavior based on real-time priority configuration information and scheduling indication from the base station. When conflicts are detected or predicted through the feedback mechanism, the UE can dynamically pause, interrupt, or adjust its SDT service execution to accommodate paging service requirements, thus reducing service conflicts while maintaining overall data transmission efficiency.

AI summary
A method for controlling a service is performed by a user equipment (UE), and includes: obtaining priority configuration information, wherein the priority configuration information is configured to indicate priorities of a small data transmission (SDT) service and of other services; determining a scheduling indication sent by a base station for scheduling the other services in a process of performing the SDT service; and determining whether to continue performing the SDT service based on the priority configuration information and the scheduling indication.
