Log Header Priority Transmission for Mobile Test Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing test systems for mobile communication terminals face issues with log data transmission due to limited storage capacity in pseudo-base station apparatuses, leading to log omission when high-speed data communication systems like LTE or WiMAX are used, causing incomplete communication logs and hindering effective testing.
Innovation Solution
A test system that separates log information into log headers and data, prioritizing the transmission of log headers before data, using a priority control unit to manage transmission buffers and buffers for log headers and data, ensuring complete log display even with limited storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If log information is transmitted to PC for display, then tester convenience is improved, but transmission speed requirement increases causing log omission when storage is limited
Solution Approach 1:
The log information is segmented into two distinct parts: log headers (containing essential metadata like timestamps, layer IDs, and communication data) and log data (containing detailed communication content). This segmentation allows the system to transmit only the critical header information when storage capacity is limited, ensuring that essential log information is preserved while reducing transmission requirements and preventing log omission.
2Loss of information
If all log information is stored in pseudo-base station apparatus, then complete log data is preserved, but storage capacity is quickly exhausted
Solution Approach 1:
The essential log header information is extracted from the complete log information and separated into a distinct data structure. This extracted header contains the most critical information needed for log display and analysis, allowing it to be stored and transmitted independently. By taking out only the essential header portion, the system preserves complete log information while minimizing storage capacity consumption in the pseudo-base station apparatus.
3Productivity
If log information is divided into headers and data, then transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The system dynamically adjusts the transmission and storage strategy based on available storage capacity. When storage is sufficient, complete log information including both headers and data is transmitted. When storage is limited, only the essential log headers are transmitted. This dynamic approach optimizes transmission efficiency while managing system complexity through adaptive behavior rather than rigid structural complexity.

AI summary
To prevent the complete omission of a log due to log information which is destroyed since it cannot be transmitted, when the communication log information of a plurality of layers is transmitted and a log is displayed at a transmission destination. A test device 10 includes a log header generating unit 151 that generates a log header including layer identification information and time information, a log data generating unit 152 that generates log data including communication data, a test-device-side transmitting unit 17 that transmits the log header and the log data to a display device 30, and a priority control unit 19 that performs control such that the log header is transmitted prior to the log data. A display control unit 35 of the display device 30 displays a log such that the log header is associated with the log data.
