Signaling Trace Command Array Reduces S1 Interface Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signaling trace methods in communication systems are inefficient as they can only carry one set of trace configuration parameters, leading to increased signaling interaction load and interrupted traces during handovers, especially on the S1 interface, when multiple traces are activated or maintained.
Innovation Solution
The method involves carrying signaling trace configuration parameters for multiple traces in a single command using an array format, allowing for efficient transmission and maintenance of multiple traces across different interfaces, such as X2 and S1, ensuring continuity and reducing the signaling interaction load on the S1 interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one signaling trace command carries only one set of trace configuration parameters, then the command structure is simple, but multiple traces require multiple messages increasing signaling interaction load
Solution Approach 1:
The patent combines multiple trace configuration parameter sets into a single signaling trace command message. The Trace Activation cell is extended to include multiple E-UTRAN Trace ID, Interface To Trace, Trace depth, and Trace Collection Entity IP Address parameters, allowing one message to activate multiple traces simultaneously, thereby reducing signaling interaction load.
Solution Approach 2:
The signaling trace command message is designed to serve multiple functions by carrying multiple trace configuration parameter sets. A single message can activate, suspend, or delete multiple traces across different interfaces (S1, X2, Uu) and for different UEs, making the command structure multi-functional and reducing the number of separate messages needed.
2Adaptability or versatility
If trace configuration parameters are transmitted separately for each trace, then each trace can be configured independently, but multiple messages are required increasing transmission overhead
Solution Approach 1:
Multiple independent trace configuration parameter sets are merged into a single message structure. Each trace maintains its independence through unique identification via E-UTRAN Trace ID, while the parameters are transmitted together in one signaling trace command, reducing the quantity of messages from multiple to one.
3Device complexity
If trace information is not carried during handover, then the handover process is simple, but traces are interrupted during interface switching
Solution Approach 1:
The patent applies preliminary action by including trace configuration parameters in the Handover Request message before the actual handover occurs. This allows the target eNB to prepare for trace continuation in advance, ensuring that traces are not interrupted during interface switching between source and target eNBs.
Solution Approach 2:
The patent ensures continuity of trace functionality during handover by carrying trace configuration parameters through the handover signaling. The trace activation is maintained continuously across the handover event, preventing interruption and ensuring uninterrupted trace collection during interface switching.
