Optimization and Troubleshooting

COMsolve provides Optimization and Troubleshooting services used to aid in finding specific problems during the rollout phases of new networks or to observe specific problems reported by consumers during the operational phase of the network lifecycle. Drive testing data is used to diagnose the root cause of specific network issues such as dropped calls or missing neighbour cell assignments. By measuring what a wireless network subscriber would experience in any specific area, wireless carriers can make directed changes to their networks that provide better coverage and service to their customers.

Drive testing requires a mobile vehicle outfitted with drive testing measurement equipment. COMsolve has multiple teams with trained engineers, technicians, vehicles and GPS guided test equipment to measure specific markets and provide either raw results or full analysis and recommendations.

Types of Drive Testing

  • Network Benchmarking
  • Optimization & Troubleshooting
  • Service Quality Monitoring

The resulting dataset produced by drive testing for each of these purposes is different. The dataset collected during drive testing field measurements can include information such as:

  • Signal intensity
  • Signal quality
  • Interference
  • Dropped calls
  • Blocked calls
  • Anomalous events
  • Call statistics
  • Service level statistics
  • QoS information
  • Handover information
  • Neighbouring cell information
  • GPS location co-ordinates

Network Benchmarking

For network benchmarking, COMsolve used sophisticated multi-channel tools to measure several network technologies simultaneously for comparison purposes, and provide detailed reports regarding competitive strengths and weaknesses. COMsolve executes Drive Testing to gather network benchmarking data from the mobile network operator and collect accurate competitive data on the true level of their own and their competitors’ technical performance and quality levels.

Service Quality Monitoring

COMsolve services typically involve making test calls across the network to a fixed test unit to assess the relative quality of various services using Mean Opinion Score (MOS). Quality of Service (QoS) monitoring focuses on the end user experience of the service, and allows mobile network operators to react to what effectively subjective quality degradations by investigating the technical cause of the problem in time-correlated data collected during the drive test. Drive Testing can be conducted at any time on a live network and very rarely will there be any network intrusion.

COMsolve provides planning and optimization services for wireless technologies (mobile and fixed). We utilize the newest suite of test equipment, enabling us to troubleshoot and optimize wireless networks such as CDMA, GSM, UMTS, HSPA+, LTE, WiFi, WiMAX. Etc.
