MTS RUSSIA SELECTS COMARCH AS A STRATEGIC PARTNER FOR SERVICE ASSURANCE AND SERVICE

INVENTORY

Comarch Next Generation Service Assurance and Comarch Service Inventory Management solutions are

to be used for managing MTS mobile and fixed networks in Russia.

Comarch NGSA and Comarch Service Inventory Management solutions will be implemented as a part of a

project for MTS Russia aimed at creating customer-centric network operation. The combined solution provides MTS

with a functionality for improving the quality of customer- and resource-facing services across its network domains.

This will be accomplished by closing the gap between traditiona l network monitoring and service-oriented, process-

driven network management. The solution is equipped with an efficient event correlation engine which simplifies

monitoring complex services, automates finding potential problem root causes and enriches events with advanced

information. The embedded BPM (Business Process Management) Engine is specifically designed to manage a telecom

operator's processes. The convergent solution will be used to manage both mobile and fixed MTS networks all over

Russia.

- "Partnership with Comarch allows MTS to optimize costs and ensure that high-quality reliable services are provided

to our customers. We decided to install the NGSA solution that allows complex services implementation while ensuring

efficient network and service monitoring. I am confident that Comarch solutions will enable MTS to accomplish

transition from a network-centric towards a customer-centric OSS ecosystem with an ultimate goal of creating the

best customer experience" - commented MTS Vice President and Chief Technology Officer, Andrey Ushatsky.

- "I am very pleased that Comarch has been selected to deliver key systems for network and service assurance as well

as service inventory to MTS. Comarch OSS solutions will contribute to improving the quality of MTS services andincreasing customer satisfaction." - sa id Jacek Lonc, Member of the Board, Comarch AG.

Comarch Next Generation Service Assurance is a solution that augments traditional resource-centric fault

management and transforms it towards a customer-centric service assurance solution. Apart from robust network

alarm processing with advanced root cause analysis capabilities, the system calculates the impact on customer- and

resource-facing services by giving insight into customer perception of network faults. This enhances traditional

network monitoring with information about real impact on customer service. It enables a reaction to service incidents

before a customer issues a complaint, which forms an essential part of a pro-active approach to service monitoring.

Main functionalities and benefits of the convergent Comarch solution chosen by MTS include:

Comprehensive service modelling and monitoring engine, providing the mapping between resources andservices, even for complex cases

Progressive fault management system, including advanced event enrichment (with use of information fromexternal systems) and strong correlation engine to assure clear data presentation and root cause analysis Automatic business impact analysis giving priorities to tasks related to business information (e.g. SLA) Process management system controlling and organizing the complex workflow in the areas of incident and

problem management
