EXTREMELLY FAST INTELLIGENT NETWORK PLATFORMS CONSOLIDATION
FOR MOBILE & FIXED SUBSCRIBERS

ABOUT CUSTOMER: Telia Company is a Swedish-Finnish multinational telephone company and mobile network operator present in Sweden, Denmark, Estonia, Finland, Latvia, Lithuania, Moldova, Norway, Sweden, Turkey. Telia Company is the fifth largest telecom operator in Europe today and continues building on its pioneering spirit and high technology expertise within both fixed and mobile communications inherited from its predecessors.

 

INTELLIGENT NETWORK: The Intelligent Network (IN) is a telephone network architecture that separates service logic from switching equipment, allowing new services to be added without having to redesign switches to support new services. This provides the network operator with the means to develop and control services more efficiently. New capabilities can be rapidly introduced into the network. Once introduced, services are easily customized to meet individual customer’s needs.

RISK

MITIGATION

The key challenges faced by the Project team were:

BUSINESS
OUTCOMES

Telephony mobile VAS services migration to the common Telia Lithuania IN platform was implemented on time and within the established budget. The switchover from the legacy platform was done without any interruption to the Client production process or any impact on subscribers’ services. 


The project of intelligent network platforms consolidation for mobile and fixed subscribers brouhgt main outcomes such as:

Lower system’s support costs by 45% ;

Improve existing services and develop new sources of revenue by accomplishing the following:

​

  • The new services will be introduced rapidly; 

  • The Telia Lithuania will be able to provide service customization to meet individual customer’s needs;

  • We helped to establish vendor independence: a major criterion for service providers is that the software must be developed quickly and inexpensively. To accomplish this, suppliers must integrate commercially available software to create the applications required by service providers.
