Network Optimization

 
 

Nova RAN Optimizer is a multi-technology & multi-vendor radio optimization tool which uses network equipment Call Trace files to measure RF coverage & quality of the network. It facilitates daily radio optimization tasks by automating recurrent analysis and reduces drastically the number of drive tests.

Coupled with Nova Network Analytics dashboards of radio KPIs, Nova RAN Optimizer is the perfect tool for radio optimization engineers to maintain and optimize a high level of QoS on the radio network.

RF coverage & quality maps

Nova RAN Optimizer includes a geo-location engine that leverages radio measurement data to produce RF coverage and quality maps. Nova RAN Optimizer enables measuring the impact of optimization tasks on the network (tilting, azimuth & power modification).

Geo-located Radio Coverage

 

Multi-point geolocated positioning

Radio engineers can obtain multi-point geolocated positioning every second for every subscriber and better understand issues they experienced. This geolocated information can be injected in operators’ big data lake to enrich customer experience analysis and can be leveraged by marketing for geo-fencing, geo-marketing etc. to create new revenue streams.

 

Radio sanity checks

Nova RAN Optimizer provides automated analysis which detects incorrect radio settings and generates recommendations to reach optimal QoS. This analysis concerns neighbor list optimization, BA list / PSC / PCI clashes, crossed sectors, cell overshooting, etc.

 

Advanced predictive algorithms

Nova RAN Optimizer's advanced predictive algorithms distinguish indoor/outdoor, static/mobility calls (high speed train, motorways) and coverage & traffic hotspots. This information can be used to improve network planning by recommending additional small cells, proposing mobility scenarios monitoring, etc.

 

 

Configuration parameter consistency

Maintaining a consistent database of network configuration parameters is a challenge for any operator and any parameter inconsistency can have a negative impact on network QoS. Nova RAN Optimizer includes a set of consistency checks that identifies errors in configuration parameters settings such as out of range values, missing elements, conflictive settings. The proprietary algorithms enable self-configuration of newly deployed sites or technological features to minimize human intervention and reduce operational costs.

 

End-to-end troubleshooting

Astellia’s Nova solution analyzes 100% of real subscriber traffic and offers native end-to-end troubleshooting from radio to core network by exploiting RRC call traces and probe data. The solution proposes LTE IMSI Enrichment and individual IMSI geolocation for advanced troubleshooting.
