Service management and user control thereof are becoming increasingly important, requiring a wider scope of TMN systems. PRISM addresses the investigation of TMN reference configurations (RC's) for the management of IBC services, the associated resources and the user control of those management services. The primary project objectives are:
- To define service management RCs, including its interworking with that for network management.
- To define the user control aspects in communication management and related service management.
- To define security of management requirements and their impact on the service management RC.
- To apply the above aspects to a set of specific case studies.
- To participate in the consensus forming process, by contributing to RACE CFSs and standardisation activities.
Service management and user control of service management are becoming increasingly important, requiring a wider scope of telecommunication management network (TMN) systems. The main objective of the research was to investigate TMN reference configurations (RC) for the management of integrated broadband communications (IBC) services, the associated resources and the user control of those management services. The primary objectives of the research were:
to define a service management RC, including its interworking with that for network management;
to define the management and security requirements and their impact on the service management RC;
to apply the above aspects to a set of specific case studies;
to participate in the consensus forming process, by contributing to common functional specifications (CFS) and standardization activities.
The research has resulted in the following:
the requirements for management services have been assessed and modelled in terms of roles, functional areas and TMN layers;
the concept of RC has been improved and defined;
with reference to access to management services by users external to the service provider, the actors have been identified and the different requirements and services considered;
a first characterization of the boundary between the network and service layers of TMN has been made;
work on the decomposition of service management services has been carried out including a method for management service interaction detection;
initial security requirements and services have been described;
4 new CFS's are being developed;
detailed case study scenarios are in place.
The studies are organised in five streams:
- Requirements capture.
- Service and network management RC.
- Customer access to management facilities.
- TMN management services definition.
- Requirements for security in service management.
- These generic studies are being applied to VPN and UPT.
RC's are being created in each case, to validate and improve the modelling framework.
- Definition of methods for service management description.
- Responsibilities for network and service management.
- Creation of management services from components.
- User control over resources.
- Security of service management.
- VPN & UPT management.
It is intended that future service management systems will be designed according to the PRISM framework of ideas, since they are a natural extension to TMN and services thinking. A book will be published in Autumn 1995, describing how open distributed Pan-European management systems can be specified. The main results will also be presented in CFS form for external use in standardisation bodies, and in an easily understood visual form for wider dissemination.
