>> Study Group 2 : Operational aspects of service provision, networks and performance
Question 5/2 – Network and Service Operations
- Motivation
The deployment of converging networks, technologies and services, requires new methods of network and service operations. Input to this question from the Service and Network Operations group (SNOg) and Quality of Service Development Group (QSDG) is required.
New technologies and services have been planned and/or introduced in all networks which are characterized by different profiles and which need to be handled by the network and service operations in real time. The introduction of new services and/or new networks may generate new or unusual demands in the network, and may not be fully understood when the service is introduced. Operational studies for Next Generation Networks (NGN) and services have to be further developed. The introduction of such new services and/or new networks requires the collection in real time of network and services data, additional respect to those already specified in the E.410-series of Recommendations. The need of selectivity and enhancement of Operational surveillance and control has to be further analysed to cope with the variety of service types. With the increasing numbers of Network elements (e.g. routers, exchanges) and transmission systems, failures of such facilities may have a severe impact on service if Operational actions are not pre-planned and implemented. The exchange of real time information between the network elements of the national and international networks and/or OSSs is essential for the optimization of telecommunications services and therefore it should be further investigated for inclusion into the E.410 series from an Operational perspective.
The telecommunications management network (TMN) and e-TOM (from Telemanagement Forum) can support a wide range of operational functions between a operations centre (or operations system) and network elements. The operations functions can be useful components in the other layers in the two models.
- Question
How will new methods of network and service operations be supported and achieved?
New recommendations will be developed and the E.410-series of Recommendations be updated to reflect the enhancement of network and service operations capabilities.
Studies under this Question will include for networks and services:
- Operational guidance
- Assurance
- Provisioning
- Controls
- Operational planning and organization aspects
- Operational security
- Performance
- Tasks
New and revised (E.410-series) recommendations are expected during the study period as reflected in the table below which will be updated on an ongoing basis:
