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 Prerequisites of INsSMS INsSMS creationcreation


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 Planningis a set of actions on development

of the plan describing tasksand 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
