Samsung Semiconductor India Research Automates 5G Field-to-Lab Validation
Case Studies
Samsung Semiconductor India Research (SSIR) is using the Keysight Signaling Field-to-Lab (S-FTL) solution to automate this workflow in its Bengaluru lab, converting device field logs into precisely replicated protocol test scripts.
As 5G continues to be deployed, the focus has shifted to ensuring users receive the highest quality of experience (QoE) by rapidly resolving issues reported from the field.
A significant challenge is replicating complicated field scenarios in a lab environment to identify possible solutions. This involves the complex, time-consuming process of analyzing field logs, which are often missing data or contain errors, in order to replicate the issues.
To assist its global customer base, SSIR sought an intelligent test automation solution that could replicate field issues in its Bengaluru test lab, and that would let its engineers focus on addressing field issues rather than analyzing logs or creating test cases.
SSIR chose the Keysight S-FTL solution because it enables automated test case creation from device field logs. Based on the S8701A 5G Protocol R&D Toolset, the solution analyzes field logs for 5G / 4G and IMS, makes protocol-based adjustments to ensure protocol-compliant behavior, and then replicates the field scenario as a test script.
The S-FTL solution features an open input log template that accommodates various formats, enabling faster adoption into the workflow. By using the solution, SSIR has significantly reduced the time it takes to replicate field scenarios in the lab and increased the time its engineers spend on improving end-user QoE.
The S8701A Protocol R&D Toolset provides the underlying 5G / 4G and IMS protocol engine for the S-FTL solution, enabling automated, protocol-compliant test case generation directly from device field data.
By using the Keysight S-FTL solution, SSIR has helped resolve a wide range of issues from real-world scenarios such as voice / data calls, handovers, 5G to 4G mobility, and carrier aggregation for deployments ranging from single SIM, dual SIM, and dual connectivity.
