Planning of Integrated Network and Service Management Systems

for the Russian Telecommunications Market

Management Center of Telecommunications Networksand Services


Planning of Integrated Network and Service Management Systems for the Russian Telecommunications Market

Availability of the competitive environment among telecommunication operators Necessity of creation of the new high-quality and profitable services Necessity to maximize the investments repayment Limited capacities of staff and informational resources for management systems development High costs connected with management systems development Necessity of the flexible approach to perspective network requirements and services

Prerequisites of INsSMS creationPrerequisites of INsSMS creation


Statement of the ProblemStatement of the ProblemDevelopment of the approach describing:

Use of modern methods for networks and telecommunications services management planning

Evolutionary approach to new management technologies, including

• Integration and flexibility in transition from OSI models to open distributed processing (ODP)

• Providing interactive domain model (IDM)

Consideration of the specific features of the Russian telecommunications networks

Consideration of the existing technical solutions for management and staff-organizational structure of the management centers

Use of convenient planning and designing procedures



Structure of transmission networks equipment Structure of switched networks equipment Structure of access networks and SS7 network equipment Features of providing services Plans of networks development and modernization considering its management Features of existing management systems equipment Existing staff-organizational structure of management centers

Initial DataInitial Data



Special features of Russian PSTNSpecial features of Russian PSTN Availability of large number of analog networks with

electromechanical switches Availability of the private operators providing modern

telecommunications services By using, on networks of various maintenance methods

(preventive, corrective, controlled) Availability of users system of payment for local telephone

calls Availability of large numbers of the equipment suppliers of

the separate operators Necessity of provisioning of network operating processes in

extreme situations



Management PlanningManagement Planning

is a set of actions on developmentof the plan describing tasks

and interconnected networks and services management processes and as well as

management systems and management centers realizing these processes with the

help of hardware, software and the personnel within the area of servicing
