DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to subscriber administration in a telephone network from which there is access to an intelligent network.


BACKGROUND OF THE INVENTION

The need to support and provide different services has led the development of telecommunication networks in the direction of what is known as an Intelligent Network IN. An intelligent network can be defined as architecture that is applicable to most telecommunication networks, irrespective of network technology. The aim is to create, control and manage teleservices giving added value. One characteristic of the intelligent network is to provide modular functions that are independent of a service used and can be connected to one another as components when new services are provided, which makes it easier to define and design new services. Another characteristic is that the supply of services is independent of the telecommunication network. The services are separate from the lowest physical network structure, whereby they may be distributed.
In recommendation CS-1 (Capability Set 1), CCITT defines an Intelligent Network Conceptual Model INCM. The model consists of four levels, each of which represents an abstract view of the possibilities offered by the intelligent network. The second highest level in the model is a Global Functional Plane, and it includes the view of the intelligent network as Service Independent Building Blocks SIB, from which desired features of a service and desired services are assembled by the use of service logic. This level also comprises a Basic Call Process BCP, which covers the whole network, and a Point of Initiation POI and a Point of Return POR between BCP and SIB.
A Service Switching Point SSP gives the user access to the network and makes all the necessary selections. It is able to detect the service requests of the intelligent network. Operationally, SSP contains call management and service selection functions. A Service Control Point SCP comprises the programs of the service logic that are used for producing intelligent network services. A Service Data Point SDP contains the data that the programs of the SCP service logic use to produce individualized services. SCP and/or SMP can use the services of SDP either directly or via a signalling network that uses an INAP protocol. Supplementary services offered by an Intelligent Peripheral IP include e.g. voice messages, synthetic voice and speech detection means, and voice generation. A Service Switching and Control Point SSCP consists of SCP and SSP in one node. A Service Management Point controls the service management, supply and performance, and can be connected to all other physical entities. Examples for the operation include database management, network control and testing, network traffic management, and network data collection. A Service Creation Environment Point SCEP is used for defining, developing and testing intelligent network services, and for supplying the service to SMP. An Adjunct AD corresponds operationally to the service control point SCP but is connected directly to SSP. A Service Node SN can control the intelligent network services, and it communicates with the users. It communicates directly with one or more SSPs. A Service Management Access Point SMAP is a physical entity that provides certain users with a connection to SMP.
A Basic Call State Model BCSM defined in connection with the intelligent network is a description of the facilities of the call management function needed for setting up and maintaining a connection between users. It detects the points (detection point) in the call and connection process in which the IN service logic entities can interact with the basic call and connection management functions. It provides a basis for describing the basic call and connection actions that may lead to activation of an IN service logic entity and description of the points where the transfer of the control may be performed.
FIG. 2 illustrates one known basic service in an intelligent network, i.e. number conversion service. On
