All described below for Moscow city & moscow region LTE (TDD) network planing. Planning and optimization GSM \ DSC network ( UMTS - GSM refarming) Controlling KPI's Drive-test analysys

UTRAN KPI monitoring, Topology, UTRAN parameters and Neighbor lists optimization using Optimi, Shema Mentor, Testing and implementing new features for UTRAN, UTRAN optimization based on statistical analysis, customer complaints and measurements results, Working with Ericsson OSS services and equipment (include W11)

Network KPI monitoring, RAN development, Data originating for integrating new BS (Node B), Checking-up construction projects of RAN objects (AutoCad only), Logical and physical RAN optimization on basis of statistic analysis, measured results, customer complaints (changes of azimuths, tilts, BS power, frequency planning etc), Data originating for equipment or license orders (Antenna and feeder elements, BS, BSC\TRC\PCU & etc.), Working with Ericsson OSS services and equipment Achievements: • Designing, calculation, and modelling UMTS network in Maikop, Novorossisk using Mentum Planet; optimization of physical parametres of sectors (azimuths, tilts and etc.) using Schema OptiPlanner; expected coverage and service maps are created. • The initial data for UMTS Rollout in branch has been prepared: antenna-feeder devices, Node B solutions, power supply solutions, upgrading of the existing equipment and antenna-feeder devices.

Network KPI monitoring, GSM RF planning and optimization, RAN statistic analysis, Data originating for integrating new BS (Node B), Worst cell analysis, Customer complaints Processing, Cells and services troubleshooting, Checking-up construction projects of RAN objects (AutoCad only), Working with Ericsson OSS services and equipment Achievements: • Improvement of the RxQuality parameter has been obtained by RAN optimizaton: RF planning, integating new BSC, link budget, azimuths and tilts optimization, neighbours optimization, hierarchical cell structure has been changed. As a result, about 25% of cells has been considerably improved.
