Cigale Abis

Push GSM optimisation & troubleshooting down to radio level

In most cases, network issues are related to radio access network (80%). Traditional methods such as OMC statistics and drive tests are not sufficient to analyze them precisely. They are time and cost-consuming.

A fully end-to-end analysis can be handled when Cigale Abis is used in conjunction with Cigale GSM (A-interface) and Core CS. Based on the analysis of subscribers’ real traffic on the Abis interface in both uplink and downlink, Cigale Abis is designed to help operators to:

• Troubleshoot radio issues,
• Optimize radio network coverage, capacity & quality.

Cigale Abis provides highly accurate and detailed visibility of the radio behavior. It reduces the number of drive tests and improves BSS network efficiency.

Troubleshooting down to radio level

Using Cigale Abis, radio engineers are able to:

• Understand & trace radio call drops, interferences and congestion,
• Identify defective equipment & cabling,
• Analyze radio conditions experienced by the end-user.

In case of a high level of radio call drops for instance, engineers can easily investigate and identify the root cause through seamless top-down troubleshooting method from radio-specific Key Performance Indicators to protocol decoding and radio measurements.

Radio optimization down to TRX level

Radio-specific KPIs and radio metrics distributions are provided in Cigale Abis to help the user to:

• Easily check and evaluate the impact of radio tuning,
• Ensure BSS network stability and efficiency,
• Validate integration of new 2G sites.
