Abstract

Method and communication system for providing a value added service, such as an intelligent network (IN) service, which is available in a first network (5), to a subscriber (3) in a second network (7). The first network (5) comprises a first network node (11) for executing the value added service. The method comprises detecting in a terminating call to the subscriber (3) that the subscriber (3) desires to use the value added service, forwarding control of the call towards the first network node (11) associated with a forwarding number in the first network (5), executing the value added service by the first network node (11), and, when necessary, further directing the call towards the subscriber (3) associated with the terminating call. The present method can also be applied to originating calls from a subscriber. In this case, the call is further directed towards a destination associated with the call.

6. The method according to claim 3, wherein the Service Node is a Service Control Point (SCP) or an Application Server (AS) or a Service Capability Server (SCS).

7. The method according to claim 1 wherein the call to a subscriber is forwarded using a Call Forward Unconditional (CFU) mechanism.

8. The method according to claim 7, wherein the CFU mechanism is initiated by the subscriber.

9. The method according to claim 1 wherein the call is further directed towards the subscriber by overriding the Call Forwarding Unconditional mechanism.

10. The method according to claim 1 wherein the value added service comprise one or more of the following:

Malicious Call Barring;

Personalised Greeting Service;

VPN.

11. A method for providing a value added service, such as an intelligent network (IN) service, which is available in a first network, to a subscriber in a second network, in which the first network comprises a first network node for executing the value added service, comprising:

detecting in an originating call from the subscriber that the subscriber desires to use the value added service;

forwarding control of the call towards the first network node associated with a forwarding number in the first network;

executing the value added service by the first network node, and, when necessary, further directing the call towards a destination associated with the call.

12. The method according to claim 11, wherein the detecting comprises recognizing a match of at least part of a destination number in the call with a special predefined number.

13. The method according to claim 11, wherein the detecting comprises recognizing a match of an originating number of the subscriber.

14. The method according to claim 11, further comprising directing the call to the first network node using an indexing register, in which the indexing register indicates the type of value added service associated with the forwarding number.

15. The method according to claim 14, wherein the first network is a public land mobile network (PLMN), the second network is a public switched telephone network (PSTN), the indexing register is a home location register (HLR) of the PLMN, and the first network node is a Service Node (SN) of the PLMN.

16. The method according to claim 11 wherein the first network is a public switched telephone network (PSTN) and the second network is a public land mobile network (PLMN), and the first network node is a Service Node of the PSTN.

17. The method according to claim 15 wherein the Service Node is a Service Control Point (SCP) or an Application Server (AS) or a Service Capability Server (SCS).

18. The method according to claim 11 wherein the value added service comprise one or more of the following:

Outgoing Call Screening;

Short Number Dialing;

VPN.

19. An exchange in a second network for providing communications to a subscriber, the second network being interconnectable with a first network having a first network node for executing a value added service, such as an intelligent network service, the exchange being arranged for:

detecting in a terminating call the desire of the subscriber to use a value added service provided by a first network node of the first network;

forwarding control of the call towards the first network node associated with a forwarding number in the first network; and

when necessary, after execution of the value added service by the first network node, further directing the call towards the subscriber in the second network associated with the terminating call.

20. An exchange in a second network for providing communications to a subscriber, the second network being interconnectable with a first network having a first network node for executing a value added service, such as an intelligent network service, the exchange being arranged for:

detecting in an originating call the desire of the subscriber to use the value added service provided by a first network node of the first network;

forwarding control of the call towards the first network node associated with a forwarding number in the first network; and

when necessary, after execution of the value added service by the first network node, further directing the call towards a destination associated with the originating call.

21. The exchange according to claim 20, wherein the first network is a public land mobile network (PLMN), the second network is a public switched telephone network (PSTN), and the first network node is a Service Node (SN) of the PLMN.
