Backup - 100% compliance of Core node back up policy and ensuring availability of back up all the time for any emergency handling.

Customer complaint handling - Ensure immediate action of all types of customer complains related to Data core network & data roaming, detailed investigation and proper resolution.

Field support - Extending support to central teams for new roll out including software upgrade and technical testing. Field resource alignment for any on-site activities for Data Core platform HW and new feature testing.

Change implementation and testing - Ensure accurate implementation of all types of changes, judge impact of changes pre / post service confirmation for each of the change including KPI tracking and impact analysis

Upgrade - Drive SW version and patch upgrades of Core nodes, new feature testing

Capacity Management - Ensure all NE’s HW & SW utilization is maintained at optimal level and no rejections of any type.

KPI Analysis & improvement - First level analysis on Performance related, Revenue exposure related and Customer impacting related concerns. Troubleshooting the issue by analyzing application layer/ network layer traces. Timely escalation to concerned team for resolution; monitoring of all types of core KPIs like: ASR, PDP/PDN SR, S11 SR, Inter and Intra RAU/TAU, SRVCC SR, CSFB SR, SGs LUSR etc, all types of Gx and Gy errors and success rates. Maintain all KPI above benchmarked values and work for its improvement

Caching Traffic Monitoring – Keep track on caching traffic trends, escalate and drive action in case any deviation, for any new node getting added in network verify all caching are done from nearest location

Compliance - Compliance of internal and external audit, SOPs; Lawful Interception SOP and compliance.

Inventory Management: - Ensure latest update on inventory in terms of location, HW, SW, Capacity etc. & scrapping of non-live inventory

Project Handover: Take proper HO of all new nodes from project team, ensuring all physical installation as per guideline, availability of all HLD, LLD, solution documents etc., verify all functionalities and redundancies working fine as per design

Team management & Training – Mentor all team members, enhance their technical and behavioral skills, keep them positively engaged and motivated, challenge them to bring best out of each individual. Impart technical trainings to team members
