MONITORING OF CALL FORWARDING DESTINATION
Monitoring of the final Call Forwarding destination of a terminal that has activated the call forwarding feature. An application server, in an IMS network, checks if the user of the forwarded-to-terminal has activated the call forwarding feature and the application server sends a notification to the (originating) user, indicating that the user of the forwarded-to-terminal has activated the call forwarding feature. The originating user subscribes to the service of receiving the notification and the originating user receives the notification when the user of the forward- to-terminal has the call forwarding feature activated already or attempts to forward his call's at a later point of time. Feature is known as communication diversion notification (CDIVN).
1 . A method for notifying a user of call forwarding feature activated by a forward-to-number in an Internet Protocol Multimedia Subsystem Network, said network comprising an application server said method comprising:
said application server checking if said forward-to-number has activated call forwarding feature; and
said application server sending a notification to said user indicating said user of activation of call forwarding feature by said forward-to-number.
2 . The method, as claimed in claim 1 , wherein said user subscribes for service of receiving said notification.
3 . The method, as claimed in claim 1 , wherein said user receives said notification when said user activates said call forwarding feature and said forward-to-number has call forwarding feature activated.
4 . The method, as claimed in claim 1 , wherein said user receives said notification when said forward-to-number activates call forwarding feature.
5 . The method, as claimed in claim 1 , wherein said user receives said notification in at least one of:
text message; and
audio message.
6 . The method, as claimed in claim 1 , wherein said forward-to-number is at least one of:
Session Initiation Protocol address;
Public Switched Telephone Network number; and
Cell phone number.
7 . The method, as claimed in claim 1 , wherein said user is in said Internet Protocol Multimedia Subsystem Network.
8 . The method, as claimed in claim 1 , wherein said user is in a different Internet Protocol Multimedia Subsystem Network.
9 . An application server, in an Internet Protocol Multimedia Subsystem Network, for notifying a user of call forwarding feature activated by a forward-to-number in said Internet Protocol Multimedia Subsystem Network, said application server having at least one means adapted for:
checking if said forward-to-number has activated call forwarding feature; and
sending a notification to said user indicating said user of said activation of call forwarding feature by said forward-to-number.
10 . The application server, as claimed in claim 9 , wherein said application server is adapted to enable said user to subscribe to service of receiving said notification.
11 . The application server, as claimed in claim 9 , wherein said application server is adapted to send said notification to said user in at least one of:
text message; and
audio message.
12 . The application server, as claimed in claim 9 , wherein said application server is adapted to send said notification to said user when said user activates call forwarding feature and said forward-to-number has call forwarding feature activated.
13 . The application server, as claimed in claim 9 , wherein said application server is adapted to send said notification to said user when said forward-to-number activates call forwarding feature.
