Subscriber Trace Buffering for Complete Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile and wireless telecommunication systems, such as 5G and LTE, face inefficiencies in subscriber tracing due to incomplete data collection, particularly in the initial phase of network acquisition, leading to missing crucial trace data for troubleshooting and increased bandwidth and storage consumption.
Innovation Solution
Implementing an apparatus with a processor and memory configured to buffer information prior to trace activation, allowing for complete trace data collection by correlating buffered and real-time trace information, thereby providing comprehensive troubleshooting data without the need for extensive cell-wide tracing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If cell-wide tracing is performed to ensure complete trace data collection, then trace data completeness is improved, but bandwidth consumption and storage requirements increase
Solution Approach 1:
The patent segments the tracing function into two parts: (1) buffering of essential trace information at the access node before trace activation, and (2) selective forwarding of buffered data when tracing is activated. This segmentation allows complete subscriber-specific trace data to be collected without requiring continuous cell-wide tracing, thereby reducing bandwidth consumption while maintaining data completeness.
Solution Approach 2:
The patent implements preliminary buffering of trace-relevant information (such as radio resource control messages, system information, and measurement reports) at the access node before the trace activation command is received. This preliminary action ensures that when tracing is activated, all necessary data is already available locally, eliminating the need for retrospective data collection and reducing the bandwidth required for real-time trace data transmission.
2Loss of information
If cell-wide tracing is performed to ensure complete trace data collection, then trace data completeness is improved, but storage requirements increase
Solution Approach 1:
The patent segments the storage function by maintaining buffers only at the access node for subscriber-specific information rather than storing all cell-wide trace data. This segmentation reduces storage requirements by focusing only on relevant subscriber data while still enabling complete trace analysis when needed.
Solution Approach 2:
The access node performs preliminary buffering of trace-critical information such as radio resource control messages, system information blocks, and measurement reports. This preliminary storage action ensures that when a subscriber trace is activated, all necessary data is already available in the buffer, eliminating the need for extensive storage of historical cell-wide tracing data.
3Quantity of substance
If trace activation occurs after network acquisition to reduce data collection overhead, then resource consumption is reduced, but trace data completeness deteriorates
Solution Approach 1:
The patent implements preliminary buffering of trace-relevant information at the access node before the trace activation command is received. This includes buffering radio resource control messages, system information, and measurement reports that occur during the network acquisition phase. By performing this preliminary action, the system can activate tracing later without losing early-phase trace data, thus maintaining completeness while reducing overall data collection overhead.
4Loss of information
If buffering of information is performed prior to trace activation, then trace data completeness is improved, but device complexity increases
Solution Approach 1:
The patent extracts and buffers only the essential trace-relevant information (radio resource control messages, system information blocks, measurement reports) at the access node, rather than buffering all possible data. This selective extraction approach improves trace data completeness while minimizing the complexity of the buffering mechanism by focusing only on critical data elements.

AI summary
Systems, methods, apparatuses, and computer program products for buffering of messages for more complete subscriber or user equipment tracing are provided. For example, a method can include buffering information needed for an individual trace prior to an activation opportunity of the individual trace. The method may also include providing the buffering information to a trace collection entity conditioned on the individual trace being activated.
