主要特点

  • Non-intrusive quality assurance system
  • Monitors both IP and RF communications
  • Automatic recognition of the impairment root cause
  • Compatible with any ED-137 VCS and radio system
  • ATC-specific reporting and visualization

Insightful analytics and detailed monitoring of ATC voice networks

Designed for efficient operation with modern IP based architectures

The R&S®AVQA is a non-intrusive voice assurance system that provides a multitude of integrated monitoring functions for an ATC communications system. These functions include:

  • Quality assurance reports to CAA
  • Type acceptance of new IP systems
  • Live information about disturbance to ACC admin
  • Voice quality report on ANSP interconnection (e.g. NewPENS)
  • Network quality reporting

特性和优点

Ground-ground voice assurance

Reachability and voice quality monitoring between centers and towers

The ground-ground assurance of the R&S®AVQA monitors and stores quality details about every single ground-ground call. In case of problems, the automatic impairment recognition immediately alarms the maintenance team with background information on the root cause. In addition, long-term statistics on MOS, reachability and other parameters are the basis of annual reports to civil aviation authorities.

Ground-ground call details

Ground-ground call details

Detailed information about ground-ground stream with low packet interval of 10 ms and tolerable jitter.

Air-ground voice assurance

End-to-end voice and radio system monitoring to ensure safe flights

Monitors the functions and quality of the entire air-ground communications system as well as ATC radios. The statistical analysis provides reports on VoIP KPIs in line with ED-136 requirements. In case of impairments, automated indication and alarms with root cause analysis provide important information for further investigations. The system is compatible with any ED-137-compatible radios and VCS systems.

Clearly structured call details on air-ground call with indicators and detailed information for every five seconds of each call.

Frequency monitor

Keep track of overall frequency utilization for efficient management

It is essential for ANSPs to be aware of availability on the frequency spectrum. The R&S®AVQA’s frequency monitoring function gives the most efficient overview. In addition, impairments such as long-pressed PTT and SQL drops cause immediate alerts, which helps remedy issues faster.

Frequency utilization monitor

Frequency utilization monitor

Real-time monitoring of each channel's individual utilization provides valuable insights into how it can be better adjusted for the particular load.

Radio channel statistics

Squelch and noise power level monitoring

The RSSI monitor of the R&S®AVQA is a prime example of efficient self-diagnostics. The monitor enables the network manager to keep track of the RSSI value at every receiver without any additional RF monitoring equipment. This is useful for quickly localizing a faulty receiver or a related issue, e.g. a misaligned antenna.

RSSI statistics

RSSI statistics

The RSSI monitor of the R&S®AVQA extracts vital RF performance analytics and summarizes them centrally for a clear overview.

Loopback monitor

Insightful closed-loop monitoring of the entire communications chain

The loopback monitor of the R&S®AVQA uses patented techniques to check end-to-end voice system functionality. The R&S®AVQA thereby extends its scope to the RF aspects of the network and can provide a very broad system view for the network administrator. As the name suggests, the loopback monitor compares different receivers’ responses to the signal transmitted by the ground based radios.

The loopback monitor compares signal strength and reception delay to spot potential problems.

Non-intrusive monitoring

Probes of R&S®AVQA are connected via TAPs or mirroring ports to the monitored environment. This one-way connection ensures there is no way to influence the monitored environment. The analysis of the traffic is executed locally on the probes and only summary data (QDRs) are send back to the AVQA Manager.
