Abstract

A method for enhancing an intelligent network service and an intelligent network including service switching points and at least one service control point, the intelligent network being adapted to initiate an intelligent network service when detecting at a service switching point a detection point defined by a call state model and triggering a service, and the intelligent network being further adapted to set at the service switching point, as a response to the initiation of an intelligent network service at one of the detection points, one or more detection points to trigger or not to trigger one or more intelligent network services.

Claims

1. A method for enhancing an intelligent network service, the intelligent network comprising service switching points and at least one service control function, the method comprising:

initiating the intelligent network service when detecting at a service switching point a pre-defined call event or a detection point defined by a call state model and triggering a service; and

setting, as a response to the initiation of an intelligent network service after detecting a detection point or call event, one or more detection points or call events at a service switching point to trigger or not to trigger one or more intelligent network services.

2. The method of claim 1, further comprising attaching, to an intelligent network service information on the detection points or call events which have been set to trigger, at least one of the intelligent network service in question or other intelligent network services, whereby the setting of the detection points or call events at the service switching point as a response to the initiation of an intelligent network service at one of the detection points or call events occurs using said detection point or call event information attached to the intelligent network service being initiated.

3. The method of claim 2, wherein the initiation of the intelligent network service occurs according to the intelligent network service trigger data included in the service switching point, whereby information on detection points or call events is attached to the trigger data of the intelligent network service and the setting of the detection points or call events occurs using the trigger data of the intelligent network service being initiated.

4. The method of claim 1, 2 or 3, further comprising setting, when an intelligent network service is initiated, all detection points or call events not to trigger said intelligent network service.

5. The method of claim 1, further comprising:

attaching, to the intelligent network service, information on the intelligent network services whose initiation is to be prevented or allowed as a response to the initiation of said intelligent network service; and

retrieving, from the call state model, as a response to the initiation of an intelligent network service at one of the detection points or call events, information on the detection points or call events which have been set to trigger said intelligent network services whose initiation is to be prevented or allowed, whereby the setting of the detection points or call events at the service switching point, as a response to the initiation of an intelligent network service in one of the detection points or call events, occurs using said retrieved information.

6. The method of claim 5, wherein the initiation of the intelligent network service occurs according to the intelligent network service trigger data included in the service switching point, whereby information on the intelligent network services whose initiation is to be prevented or allowed, as a response to the initiation of said intelligent network service, is attached to the intelligent network service trigger data.

7. The method of claim 1, 2, 3, 5 or 6, wherein

the service switching point sends a notification to the service control function when it detects a triggering call event, whereby the notification initiates an intelligent network service at the service control point, and

setting the call event to non-triggering prevents the sending of the notification.

8. An intelligent network comprising:

service switching points; and

at least one service control function;

the intelligent network being adapted;

to initiate an intelligent network service when detecting at a service switching point a pre-defined call event or a detection point defined by a call state model and triggering a service, and

to set at the service switching point, as a response to the initiation of an intelligent network service after detection of a detection point or call event, one or more detection points or call events to trigger or not to trigger one or more intelligent network services.

9. The intelligent network of claim 8, wherein the intelligent network is further adapted to attach, to an intelligent network service, information on the detection points or call events that have been set to trigger at least one of the intelligent network service in question or other intelligent network services, whereby the intelligent network is adapted to set the detection points or call events at the service switching point using said detection point or call event information attached to the intelligent network service being initiated as a response to the initiation of an intelligent network service at one of the detection points.

10. The intelligent network of claim 9, wherein the initiation of the intelligent network service occurs according to the intelligent network service trigger data included in the service switching point, whereby the intelligent network is adapted to attach information on the detection points or call events to the intelligent network service trigger data and to set the detection points or call events using the trigger data of the intelligent network service being initiated.

11. The intelligent network of claim 8, 9 or 10, wherein the intelligent network is further adapted to set all detection points or call events not to trigger an intelligent network service when said intelligent network service is initiated.

12. The intelligent network of claim 8, wherein the intelligent network is further adapted

to attach to the intelligent network service information on the intelligent network services whose initiation is to be prevented or allowed as a response to the initiation of said intelligent network service, and

to retrieve from the call state model, as a response to the initiation of an intelligent network service at one of the detection points or call events, information on the detection points or call events which have been set to trigger said intelligent network services whose initiation is to be prevented or allowed, whereby the intelligent network is adapted to set the detection points or call events at the service switching point as a response to the initiation of an intelligent network service in one of the detection points or call events using said retrieved information.

13. The intelligent network of claim 12, wherein the initiation of the intelligent network service occurs according to the intelligent network service trigger data included in the service switching point, whereby the intelligent network is adapted to attach information on the intelligent network services whose initiation is to be prevented or allowed as a response to the initiation of said intelligent network service, to the intelligent network service trigger data.

14. The intelligent network of claim 8, 9, 10, 12 or 13, wherein the service switching point sends, to the service control function, a notification when the service switching point detects a triggering call event, whereby the notification initiates the intelligent network service at the service control point, and setting the call event to non-triggering prevents the sending of the notification.

15. A network element comprising an intelligent network service switching point, the service switching point being configured:

to initiate an intelligent network service when detecting a predefined call event or a detection point defined by a call state model and triggering a service, and

to set, as a response to the initiation of an intelligent network service after detection of a detection point or call event, one or more detection points or call events to trigger or not to trigger one or more intelligent network services.
