5G Baseband Software Frontdesk Troubleshooter
About us & the job
In our daily work we are responsible for the maintenance of the software embedded into the Distributed Unit (DU) including PHY, MAC, and RLC layers on gNB side. The software (in C language) is executed on a proprietary hardware platform. Both software and hardware belong to our Customer, who leads in the telecommunication industry and supplies essential hardware and software for Radio Base Stations, from GSM up to 5G to mobile operators.
We are responsible for the last Tier 3 of customer support. Also, we take responsibility for the baseband software. After receiving the Trouble Report (TR) we need to state if the issue is software related or not. When we face a software issue then we forward the ticket to the dedicated R&D team that prepares the fix in code; otherwise, we are supporting upper tiers of customer support in analysis. Also, we cooperate with testers and labs who test the newest software - so we handle internal TRs as well.
Most of the issues we cope with are related to software, interference, coverage, hardware, optimization, environment, or other undefined issues. During our work, we use many scripts for analyzing large volumes of data.
Use Cases
After upgrading the software, the customer observed a crash on 5% of nodes. Crash disappears after a downgrade of the software.
Spontaneous throughput degradation after locking and unlocking the cell.
Voice quality degradation.
Sleeping cell.
