The project involved the complete dual mode UE stack development for UMTS and GSM/GPRS based on the current 3GPP specifications. The development included the design and development of all the UMTS layers and GSM/GPRS layers C and C++ language.
NEC/Nokia RAN Enhancement, Upgrade and Maintenance, Hutchison 3, UK (2005-2006)
Senior Consultant – UTRAN design, optimization and testing
Project involved enhancement, upgrade and the regression testing of the NEC/Nokia Node B and RNC. Upgrade of Node B and RNC involve latest version of software, new hardware components or cards. After the upgrade the project involve the regression testing of the Node B and RNC according to the Hutchison 3’s agreed test plans.
1. In case of test failure during the regression testing analyse the network and UE logs and raise the defect on UE (vendors) or RAN (NEC or Nokia) through mercury test director.
2. Follow the defect raised and get the fix from the corresponding source and retest the fix. Close the defect if the fix passes the particular test case.
