Network services
Services provided hereunder let operators optimize employment of radio equipment working in their network. Our advantage is that we impartially monitor operation of equipment from different manufacturers used in the operator’s networks, and make unbiased assessments.
The service of optimization of radio equipment of a GSM/UMTS network using equipment from different manufacturers gives operators an opportunity of comprehensive analysis of network operation on the basis of information about the quality of communication of all network users. At that, operators can remedy defects not detected by standard troubleshooting methods, discover specific network problems (e.g., poor handover operation), prepare matrixes of mutual interference, receive recommended changes in the "neighbor" lists for reliable handover among cells, as well as recommended changes in output power of base stations and antenna tilt angles and recommended assignment of base station frequencies (including in the event of use of pseudorandom switch of working frequencies).
The core services provided by our company include the following:
- Verification of the current radio network state («diagnosing»);
- Verification of the current access network state («diagnosing»);
- Performance of measurements (drive tests) on the operator’s network;
- Network optimization of the «general cleaning» type;
- Current network optimization – remedy of small defects and negative effects of the launch of new BTS or software versions;
- Review of user complaints;
- Planning of so-called “in-building solutions”” using distributed antenna systems, micro and pico base stations, repeaters, etc.);
- Various combinations of the above options.
There are the following functional elements of the optimization process:
Radio planning.
Calculation of radio network parameters (physical and database), assessment of the possible line of and effect from optimization, generation of recommendations for modification of radio network parameters, control of implementation of recommendations and comparative analysis of results. Close interaction with the operator’s radio planning and equipment supplier.
Line of collection and analysis of statistic information: network equipment
Collection, processing, analysis of network statistics, generation of recommendations for optimization, analysis of optimization effects. Close interaction with the operator’s radio planning and equipment supplier.
Line of collection and analysis of statistic information: drive tests
Collection, processing, analysis of drive test statistics, localization of bottlenecks, generation of recommendations for optimization, analysis of optimization effects. Close interaction with the operator’s radio planning.
Line of verification and modification of physical parameters of antenna-feeder devices and sites
Check of actual azimuths, antenna tilts and types; standing-wave ratio measurement; check of antenna placement on sites; check of the site selection quality. Close interaction with the operator’s maintenance service.
Access network optimization
Check of access network operability and capacity, generation of recommendations regarding capacity and network optimization. Close interaction with the operator’s planning and equipment supplier.
Future – optimization of operation of different services at large (“end-to-end performance”, tests from the user’s viewpoint).
