Abstract

In accordance with the invention, at least at one exchange at least one state model or a service-specific portion of the state model, such as a call segment is formed for each service associated with the same party (A, B) of the same call, with which portion a connection to the control point of the intelligent network service is operatively associated.

Claims

1. A method for providing intelligent network services to a call having at least two parties, the call comprising an incoming call control and an outgoing call control, the method comprising:

connecting multiple intelligent network services to at least one of the at least two parties of the call;

modeling at least one of the incoming call control and the outgoing call control by a state model;

operatively associating the modeled call control with a connection to a service control point of an intelligent network;

forming at least one service-specific portion of the state model for each of the multiple intelligent network services; and

operatively associating the at least one service-specific portion with a connection to the service control point of the intelligent network.

2. A method according to claim 1, further comprising forming at least one additional service-specific portion of the state model in preparation for at least one future service before a need for forming the at least one additional service-specific portion arises.

3. A method according to claim 2, further comprising:

maintaining information on subscribers subscribing to intelligent network services requiring controlling connections; and

using the information for call routing.

4. A method according to claim 3, wherein the using comprises preparing at least one additional service-specific portion of the call state model configured to control other intelligent network services.

5. A method according to claim 1, wherein each service-specific portion is a call segment.

6. A method according to claim 1, further comprising modeling at least one of the incoming call control and the outgoing call control by several service-specific portions in a direction in question, consecutive state models or service-specific portions having a service-specific portion therebetween in a direction inverse to the direction in question.

7. A method according to claim 1, wherein the intelligent network service include a personal number.

8. A method according to claim 1, wherein the intelligent network services include a credit card service.

10. A method according to claim 1 or 9, wherein to avoid contradictory services, each state model or service-specific portion informs a next state model or service-specific portion in a direction of propagation of the call set-up about events to which the service control point is to react.

11. A method according to claim 1 or 9, further comprising modeling at least one of the incoming call control and the outgoing call control by several state models or by a plurality of service-specific portions in a direction in question, each two consecutive state models or service-specific portions having essentially only an adapter function therebetween that interconnects interfaces of two similar state models or service-specific portions.

12. A method according to claim 1 or 9, further comprising forming the service-specific portion of the state model in response to having a controlling connection in an existing state model and detecting, in a detection point, a need to establish further a controlling connection.

13. A method according to claim 1 or 9, further comprising:

providing a feature interaction manager between the state model and the service-specific portion;

associating information on mutual compatibility of the services with the feature interaction manager; and

further associating information relating to the order in which different types of services are to be placed in a chain of mutual priority with the feature interaction manager.

14. A method according to claim 13, further comprising associating the feature interaction manager with information on the mutual priority of the intelligent network services of similar type.

15. A method according to claim 1 or 9, wherein the intelligent network services include at least one of call forwarding and conference call.

9. A method for providing intelligent network services to a call having at least two parties, the call comprising an incoming call control and an outgoing call control, the method comprising:

connecting multiple intelligent network services to at least one of the two parties of the call;

modeling at least one of the incoming call control and the outgoing call control by a state model;

operatively associating the modeled call control with a connection to a service control point of an intelligent network;

forming at least one state model for each of the multiple intelligent network services; and

operatively associating the at least one state model with a connection to the service control point of the intelligent network.

16. A method according to claim 9, further comprising modeling at least one of the incoming call control and the outgoing call control by several state models in the direction in question, consecutive state models having a state model therebetween in a direction inverse to the direction in question.

17. A method according to claim 9, wherein the intelligent network services include a personal number.

18. A method according to claim 9, wherein the intelligent network services include a credit card service.
