Protocol Test Device Summary Log for Wireless Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protocol compliance testing for wireless devices is inefficient due to the need to log and analyze repetitive messages, which complicates the handling and analysis of protocol compliance data, especially in systems like 3GPP LTE Release 13 where messages may be repeated multiple times.
Innovation Solution
A protocol test device with a summary message generation unit that summarizes repetitive messages, storing this information in a message log memory, allowing for efficient handling and analysis by extracting information about message types, frame numbers, and repetition counts, and providing pointers to the original messages for detailed analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all generated and received messages are stored individually in the message log, then complete protocol compliance data is preserved, but the complexity of handling and analyzing the log data increases significantly due to repetitive messages
Solution Approach 1:
The patent merges multiple identical or similar messages into a single summary log entry that represents a group of messages. Instead of storing each message separately, the system combines repetitive messages and stores them with a single reference or pointer, reducing the overall volume of log data while preserving the ability to retrieve complete protocol compliance information when needed.
2Measurement precision
If individual messages are logged separately, then detailed message information is available for analysis, but the time required to parse and analyze the entire message log increases
Solution Approach 1:
The patent performs preliminary grouping and summarization of messages during the logging phase itself. By organizing messages into groups and creating summary entries in advance, the system prepares the log data for faster analysis later. This preliminary action reduces the computational burden during the actual analysis phase, as parsers only need to process summary entries rather than individual messages.
3Quantity of substance
If repetitive messages are logged in full detail, then comprehensive test data is captured, but the storage space required and the difficulty of identifying irregularities increase
Solution Approach 1:
The patent extracts the essential characteristics of repetitive messages (such as message type, frequency, and grouping information) and stores only these extracted features in the summary log. By taking out only the necessary information from the full message details, the system reduces storage requirements and makes it easier to identify irregularities, as the summary format highlights patterns and anomalies more clearly than raw individual messages.

AI summary
A protocol test device for testing protocol compliance of a wireless device under test comprises a wireless interface for transmitting an outgoing RF signal to the wireless device under test and/or for receiving an incoming RF signal from the wireless device under test, a processing unit for generating messages for the outgoing RF signal based on a predefined protocol and for processing messages in the incoming RF signal based on the predefined protocol, a message log memory for storing the generated messages and the received messages, and a summary message generation unit that generates a summary log message and stores the summary log message in the message log memory, wherein the summary log message comprises information about at least one of the generated messages and/or the received messages and repetitions of the respective generated message and/or the respective received message.
