DESCRIPTION:
BRIEF SUMMARY
This invention relates to an intelligent telecommunications network.
An intelligent telecommunications network comprises interconnected switching units which are arranged to connect calls between users of the network under the control of one or more intelligent units. A "user" may be a person, an item of equipment or another network and this term should be construed herein accordingly. Service control points and adjunct processors are examples of such intelligent units. When a switching unit is setting up a call in an intelligent network, it obtains call control instructions from an intelligent unit. The provision of one or more intelligent units enables additional features to be used during call set-up which are not available from the switching unit. There is a demand to increase the number of such features.
EP-A-O 618 612 shows a telecommunications network in which service processors calls on behalf of calling and called parties.
According to one aspect of this invention, there is provided a telecommunications network comprising interconnected switching units which are arranged to connect calls between originating and terminating users of the network, a plurality of individual intelligent units arranged in a distributed computing environment, and means for providing an interface between at least some of the switching units and said intelligent units, each intelligent unit including or having access to a set of service independent building blocks and a set of individual profiles of individual services provided to respective individual users of the network, some of the profiles relating to individual users of the network as individual originating users and others of the profiles relating to individual users of the network as individual terminating users, and each intelligent unit including means for combining data contained in an individual profile with appropriate ones of said building blocks to generate a service control program, whereby, at least during call set-up, a service control program generated from the individual profile of the services provided to the originating user as an originating user and acting as an agent for the originating user enters into a dialogue with a service control program generated from the individual profile of the services provided to the terminating user as a terminating user and acting as an agent for the terminating user in order to generate call control instructions.
By providing individual profiles of individual services provided to respective individual users as originating users are individual profiles of individual services provided to respective user as terminating users, a call may be set up in accordance with individual requirements of the originating and terminating users.
According to another aspect of the invention there is provided, in a telecommunications network comprising interconnected switching units which are arranged to connect calls between originating and terminating users of the network, a plurality of individual intelligent units arranged in a distributed computing environment, and an interface between at least one of the switching units and said intelligent units, each intelligent unit including or having access to a set of service independent building blocks and a set of individual profiles of individual services provided to respective individual users of the network, some of the profiles relating to individual users of the network as individual originating users and others of the profiles relating to individual users of the network as individual terminating users, a method of setting up a call between an originating user and a terminating user, said method comprising the steps of: combining appropriate ones of said building blocks with data from the individual profile of individual services provided to the originating user as an originating user to act as an agent of the origination user; combining data with appropriate ones of said building blocks with data from the individual profile of individual services provided to the terminating user as a
