1Productivity
If SDT is implemented to enable data transmission in RRC inactive state, then transmission efficiency is improved, but the ability to record and locate SDT events deteriorates
Solution Approach 1:
The network device sends configuration information to the terminal device in advance, pre-defining the parameters and formats for SDT event recording. This preliminary configuration enables the terminal device to automatically record transmission characteristic information and service characteristic information during SDT operations, ensuring event recording capability is established before SDT begins without impacting transmission efficiency
Solution Approach 2:
The recorded SDT event information is fed back to the network device through uplink signaling. This feedback mechanism allows the network device to obtain detailed SDT event data including transmission characteristics and service characteristics, enabling problem location and configuration optimization while maintaining efficient SDT operations
2Measurement precision
If comprehensive SDT event parameters are recorded, then problem location accuracy is improved, but device complexity increases
Solution Approach 1:
The SDT event recording is segmented into two distinct parts: transmission characteristic information (including beam signal measurements, CG-SDT events, RACH-SDT events) and service characteristic information (including data volume, data rate, service type). This segmentation allows the system to record comprehensive parameters for accurate problem location while organizing the recording structure in a manageable, modular way that reduces overall system complexity
Solution Approach 2:
The configuration information mechanism serves multiple functions: it defines recording parameters, specifies data formats, determines reporting triggers, and establishes feedback procedures. This multi-functional approach consolidates what would otherwise require separate complex subsystems into a unified configuration and recording framework, achieving comprehensive event tracking without proportionally increasing device complexity
