Abstract

A database is formed for providing two intelligent network services in connection with the same call, the database comprising data on the mutual compatibility of the different intelligent network services. In connection with each such call which involves at least one first intelligent network services and one second intelligent network service, an exchange receives the data on the first intelligent network services. If this data is sufficient for arming detection points, the exchange arms the detection points from which the first intelligent network services will be activated if the activation criteria are met during the call. The exchange also determines the data for arming a second detection point from which the second intelligent network service will be activated if the activation criteria are met during the call. The exchange examines the compatibility of the second intelligent network service with the first intelligent network services on the basis of the compatibility database and uses the result of the examination to route the call.

Dependent claims

A method for providing at least two intelligent network services in connection with a call in a telecommunications system including at least a first exchange and a next exchange each of the first exchange and the next exchange including an interface to a service control point of an intelligent network, and each of the at least two intelligent network services being associated with at least one corresponding detection point, the method comprising:

dividing the at least two intelligent network services into first intelligent network services and second intelligent network services based on at least one predetermined criterion;
maintaining information on the mutual compatibility of the at least two intelligent network services examining, by the first exchange, in connection with each call which involves at least one first intelligent network service and one second intelligent network service, compatibility of the second intelligent network service with the at least one first intelligent network service;
and
routing the call to the next exchange or part of the first exchange for activating said second intelligent network service if:
the second intelligent network service is compatible with all of the at least one first intelligent network service, and
the second intelligent network service or any one of the at least one first intelligent network service requires a control relationship to the service control point for longer than the a duration of one detection point.
