Astellia is extending its GSM solution with the Abis monitoring for radio optimisation and troubleshooting. The Cigale Abis application helps operators to check that their 2G network is fine-tuned to carry thousands of calls and SMS messages.
"In 80% of cases, network issues are related to radio access," says Astellia marketing director Gérard Erabit. "If they are not identified and solved rapidly, they result in revenue leakage, bad brand image and high customer churn. This is where Astellia intervenes with its Cigale Abis application. Based on Astellia probes that capture signaling data, Cigale Abis analyses subscribers' real traffic. The Abis interface is the ideal place to analyse precisely what users really experience in a targeted geographical area."
Cigale Abis provides engineers with key performance indicators and radio metrics distribution to optimise radio coverage and fine-tune frequency plans. Highly useful in integrating new 2G sites and ensuring smooth network equipment swaps and upgrades, it is a cheaper and more reliable alternative for drive test campaigns, with costs reduced by more than 50% in most cases.
Competitive edge for high-value customers
Demanding high-value customers such as corporate fleets and VIPs require contracts guaranteed by SLAs. In order to create a competitive edge and avoid penalty payments, operators must be ready to identify, analyse and troubleshoot complex radio GSM issues in record time. In case of failed calls, traditional investigation methods based on OMC statistics and drive tests are time-consuming and not sufficient for precise analysis.
Using Cigale Abis, engineers can trace and troubleshoot any individual communication down to radio level and analyse problems linked to handover failures, coverage holes, radio disconnections, interferences, congestion and defective equipment.
