Job Grade 8

Main Responsibility Area

Technologies 3G/LTE

Vendors Huawei

  • Should have knowledge of LTE Basics, Multi-Layer Idle and Dedicated mode parameters and understand behavior of parameter tuning
  • Required to technically deliver network planning and optimization projects according to the agreed scope of work (SoW)
  • Performs critical (sometimes escalated) design and performance activities in customer projects independently. These may include complex problem solving in projects with performance requirements and multi-vendor environment
  • Good Knowledge of LTE Call flow, Familiarity with Power Control and impact of various power setting on the LTE network
  • Identify and resolve Performance degradation in the network within prescribed timelines.
  • Perform Counter level analysis and problem isolation to arrive at an early RCA to improve network performance.
  • Traffic balancing using physical and soft parameters while ensuring KPI’s are met.
  • Good understanding of Huawei BTS hardware
  • Defines the criteria to assess network performance from end-user / service perspective and monitoring of that criteria
  • Identifies and anticipates proactively network performance issues (traffic/quality/resiliency) and provides recommendations for improvement
  • Optimizes the capacity of the network to meet traffic increase and customer requirements using either network extension or existing network modification
  • Ensures that design & optimization guaranty the capability for the network to provide end-user new services in line with customer environment, business goals/drivers and quality
  • To communicate effectively and work with a large team in collaborative mode
  • Planning the Node-B and eNB sites configuration by using RF planning tool (NetAct Planner/Atoll/Asset) and defining their related parameters site coordinates, antenna type, antenna height, antenna tilt, antenna azimuth, CPICH power, cable loss, propagation model parameters
  • Setting the specific RF parameters for the site to be integrated.
  • Analyze site performance after integration through drive test measurements and/or OSS measurements, detecting eventual problems and recommending changes to fixing problem
  • Defining and monitoring parameter consistency check rules to Maintain RAN /eNB parameter database consistency
  • Defining and monitoring KPIs reports on network, area and RNC level
  • Defining and optimizing “worst objects” reports at eNB, Node-B and RNC level, as well as troubleshoot and recommending the software changes, hardware changes or alerting O&M in case of hardware problem
  • Huawei 3G/LTE parameters detailed knowledge and optimization
  • Giving inputs in terms of capacity, quality and coverage for expansion phases
  • Implementing new features required to improve overall radio network performance
