  Network admin of Network EMS. Governing and maintaining tools (AM, FM, DB, Infra).Vendor management and governance. Improvise optimization of SO OpEx. CapEx management, Business Case compilation.Nokia EMS NetAct Readiness for the Core Virtualization Project E9000 (virtual solution) platform-based new U2k server deployment around 68 BSC & 18 RNC will be rearranged to ensure a zonal-based traffic serving area. Huawei RAN EMS U2K readiness for LTE deployment 2 U2k servers Upgrade to V2R17 on ATAE platform. E2E Technical Project Management for NIAM security system deployment. Ericsson OSS RC readiness for LTE. Show less Radio Network Performance (BSS):• Voice and Data performance analysis, correlation fault and find out the root cause of degrading performance and act accordingly to recovery from degradation. • New site (BTS) and Rehomed BTS performance monitoring depending on different KPI like MPD, Call Setup success rate, Hand over success rate, TCH or SDCCH Congestion etc..• Analysis on degraded sites and find out the root cause of degrading performance and act accordingly to recovery from degradation.Radio Network Inconsistency (BSS & MSS):• Cellular Network Administrator (CNA) database inconsistency where cell parameter related configuration mismatch in BSS or MSS and another is RBS configuration (cell, TRX, CF, IS, RX, TX, TS, Device allocation, EDGE configuration, software) mismatch.• Network quality (MPD, HO success, Call Setup Success etc.) increase in by removing these inconsistencies Show less LTE & UTRAN expansion project: Integrate eNodeBs and support field engineers during the commissioning process and troubleshooting. eNodeB / NodeB scripting using CME tool, integration, and troubleshooting using Huawei’s iManager U2000 (3000+ sites). Radio network capacity increases by adding TRU and MRFU both in 900 & 1800 bands of different laid (UL & OL).Frequency Tuning project for a region (450-600 cells) – BCCHNO, BSIC & Active-Idle BA list are changed, CGI value is also changed for both internal & external cells in BSS and MSS. Regular basis cell parameter tuning in different cells of different BSC. Ensure new node and Core network capacity integration (SDH path configuration). Implement reroute & protection of the TX path of BTS’s, Core & Service network E1’s (voice and signaling). Create pipelines in the MUXs through NMS & deleting of unused paths in the MUXs for optimizing transmission networks. Ensure proper collaboration with circle engineers for BTS, signaling, and E1s. Monitoring and Driving Partner & Vendor(s) SLA and KPI for Active and Passive Nodes. Maintaining Network Availability of more than 99.96% by scrupulous driving internal team(s) / MS vendor and IP Services providers. Show less Radio Network Integration and Optimization (BSS & MSS):• Radio network capacity increase by adding TRU (Transmitter Receiver Unit) both in Ericsson and Huawei Nodes.• Regular basis cell parameter tuning in different cell of different BSC.• EDGE/GPRS configuration and optimization.• New BTS Integration – Cell parameter load in BSS and MSS.Core Network Integration and Optimization (MSS/TSS & MGW/TMW):• New route integration and optimization between different nodes.• SIGTRAN and C7 signaling addition/deletion, SCTP Association, BICC Route with MSS, TSS, MGW, TMGW, IPSTP and BSC. • Migration of different routes between different operators.• Core Node (MSC, MSC-Server, MGW, TSC, TSS) Offloading. • Site Shifting (Re-homing) to both Ericsson and Huawei Nodes.• LAC optimization by changing LAC in a list of cells to avoid congestion.Transmission Network Integration/Optimization:• Transmission path preparation for new route.• Implement reroute & protection of the TX path of BTS’s, Core & Service network E1’s (voice and signaling).• Create pipelines in the MUXs through NMS & deleting of unused paths in the MUX’s for optimizing transmission networks.• Ensure other operators transmission connectivity Show less 2G New BTS Integration in Citrix (Ericsson) platform (over 2000 BTS) as a part of the GSM project. Cell parameter load in BSS and necessary configuration (CGI, LOCNO) in MSS also configured. Intra, internal & external neighbor are defined in both BSS and MSS. RBS configure (CF, IS, TF, TRX, TX, TS), cell tei with TRX & TX and device allocation to ensure resources for voice traffic and signaling from BTS to BSC. Ensure proper terminal-based remote support to the ROM (Regional operation & maintenance) team during Rollout and also perform PAT test to declare new BTS ON AIR. Reduce MTTR (Mean Time To Rectify) regarding BTS-related outage. Reduced Capacity monitored and ensured network availability and TCH availability. BS fault monitoring and also solved BS faults under TRX, TX, RX, and TS remotely without the physical presence of ROM members. BS fault under CF and external faults are solved along with the presence of ROM members. Ensure terminal-based fault handling regarding RBS and Radio problems. Faulty equipment monitoring from a live network and also issued TR for emergency replacement of faulty equipment. Ensure and execute Change Management on a live network and verify and optimize MoPs provided by vendors. Fixation of post-impact analysis KPI and implementation. Show less
