A detailed, comprehensive view of the network configuration is not always a given for operators. Incorrect or inconsistent base station configurations lead to significant loss of quality, which is also noticeable for customers. An increase in disconnections – known as the dropped-call rate – is another possible result, as well as connection problems or problems with voice quality.
With "COM5.Mobile Network Audit“ (formerly: CPCM Network Audit), MicroNova offers an out-of-the-box solution for the complete visualization of network parameters. It reads the current live network independently of vendor, region, and technology, and records the corresponding information in a central database for auditing.
The first step of network auditing takes place within COM5.Mobile. The system checks the content consistency of the imported live data using an integrated rules-based engine. Violations are logged according to their severity (blocking/warning) and provided to the user via report mechanisms. A user-friendly graphical interface makes it easy to manage the corresponding rules. The optional dashboard allows the results to be presented in a configurable overview.
In addition to the basic functionality that includes creating, deleting, and editing consistency checks and rules, users can generate new rules based on copies of existing ones. It is also possible to exchange rules with other users. The network auditing solution comes with a set of default consistency rules, which the user can expand as required. Common rules include checking handover connections (number of handovers per cell, target frequency, etc.), frequency plans, cell parameters, dependencies between parameters, operator-specific dependencies, and compliance with operator requirements.
COM5.Mobile Network Audit considers all parameters available via the vendor‘s respective standard OSS Northbound Interface (NBI); this also contains parameters that may have been configured automatically by a Self-Organizing Network (SON). Consequently, the solution is „SON-ready“, i.e., able to monitor SON systems. Configurable rules can be used to generate corresponding reports and alerts.
Another important functionality of COM5.Mobile Network Audit is the support of operator-specific default values (default templates) over the entire network. Users can easily create configuration templates according to certain criteria and check them against the live network. Potential configurations include indoor/outdoor stations, stadiums, and events, etc. All imported network configurations are archived and available for further comparisons as well as evaluations (history function). This makes it possible to monitor Service Level Agreements (SLAs) between the network operator and third-party companies (managed service).
Thanks to the vendor-neutral and cross-technology comparisons, MicroNova‘s auditing system can play to its strengths, especially in the areas between management regions of different vendors. In this case, the standard features of proprietary systems are usually inadequate. Since COM5.Mobile Network Audit already stores a complete map of the Radio Access Network (RAN) within a central database – including history – the system can be connected as a cross-network data source for comparison with other systems. Examples include inventory, optimization, and measurement.
The network auditing solution from MicroNova allows a complete review of the network without needing to include (off-the-shelf) planning tools.
