Mobile Signaling Trace Control With Network-Side Content Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile communication systems face high signaling overheads during signaling tracing due to the need for network elements to add tracing identifiers to interaction signaling, especially in full-link tracing scenarios involving large numbers of users, which affects network efficiency and reliability.
Innovation Solution
A signaling tracing control device generates a tracing identifier for user equipment and transmits start indication information to network-side devices, including internal identifiers and specified content, allowing the network-side devices to mark traced content with the identifier, thereby reducing the need for additional signaling overheads by not adding tracing identifiers to interaction signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network elements add tracing identifiers to interaction signaling for full-link tracing, then signaling tracing capability is improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by having the network-side device mark traced content with the tracing identifier before the content is transmitted. The tracing identifier is attached to the content at the source (network-side device) rather than being added to each interaction signaling message during transmission. This preliminary marking approach enables full-link tracing capability while avoiding the accumulation of signaling overhead that would occur if identifiers were added to every signaling interaction.
2Measurement precision
If tracing identifiers are added to interaction signaling, then tracing accuracy is improved, but network efficiency deteriorates
Solution Approach 1:
The patent implements preliminary action by marking traced content with the tracing identifier at the network-side device before transmission. This ensures that the content carries the necessary tracing information from the source, maintaining tracing accuracy without requiring repeated addition of identifiers to each interaction signaling message, thereby preserving network efficiency.
Solution Approach 2:
The patent extracts the tracing identifier attachment operation from the interaction signaling processing. Instead of adding identifiers to each signaling message (which would reduce network efficiency), the identifier is extracted and attached only to the traced content itself at the network-side device. This separation allows tracing accuracy to be maintained while interaction signaling can proceed efficiently without repeated identifier additions.
3Difficulty of detecting and measuring
If network elements perform full-link tracing for all users, then fault analysis capability is improved, but system complexity increases
Solution Approach 1:
The patent applies self-service by enabling the network-side device to autonomously mark traced content with tracing identifiers without requiring complex coordination with multiple network elements. The network-side device independently performs the marking operation on content based on local identification, reducing the need for complex system-wide coordination and thereby lowering overall system complexity while maintaining full-link tracing capability for fault analysis.
Data Source
AI summary
In a communication method, a signaling tracing request to trace specified content of user equipment in a mobile communication system is received. A tracing identifier of the user equipment associated with the signaling tracing request is determined. An internal identifier in the mobile communication system for the user equipment is obtained. Start indication information is transmitted to a network-side device. The start indication information includes the tracing identifier, the internal identifier in the mobile communication system, and content information that indicates the specified content. The start indication information initiates signaling tracing. From the network-side device, content that is traced is received based on the internal identifier in the mobile communication system and the specified content. The content is marked with the tracing identifier.
