Motorola Inc. today announced the successful delivery of its multi vendor intelligent optimization service on Ukrainian Mobile Communications (UMC) multi-vendor wireless network. UMC, Ukraine’s leading network operator, employed Motorola’s multi-vendor GSM Radio Access Network (RAN) Optimization Service to help generate additional network traffic without capital investment and improve the end-to-end performance of its network in the Kharkov region.

As a result of Motorola’s optimization services, UMC’s service improved as the number of dropped calls decreased by 26 percent and the mean time between dropped calls increased. In addition, the volume of traffic across the network grew considerably contributing to increased call revenue[1].

“Providing our customers with a world-class experience is of paramount importance for UMC”, said CTO Vladimir Pashchuk, UMC’s chief executive officer. “Motorola’s optimization service produced excellent network performance improvements within a short time, allowing us to pass on the benefits to our customers. Moving forward, we are keen to work with Motorola to further improve the other parts of UMC’s network throughout the Ukraine.”

“Motorola’s RAN optimization service, based on actual user data, provides an innovative and proven alternative to traditional optimization methods and particularly helps to improve performance in a multi-vendor environment,” said Margaret Rice-Jones, corporate vice president Motorola Inc., and region management Motorola Networks EMEA. “UMC required a new and improved plan in preparation for increases in network activity and despite some tough timescales we produced outstanding and valuable results that clearly demonstrate Motorola’s comprehensive services expertise.”

Motorola’s multi-vendor RAN optimization service provides operators with a comprehensive analysis from actual user data that includes the following:

- Fault clearance not identified by standard fault management methods
- Identification of specific network problems such as poor handover performance
- Carrier to Interference (C/I) matrices
Recommended changes to cell neighbor lists to ensure appropriate cell handovers
- Recommended changes to base station power output and antenna tilts
- Recommend frequency planning for fixed, broadcast control channel, and hopping carriers
