NOTIFICATION OF TOO MANY "NO ANSWER" OF FORWARDED TO NUMBER
Method and system for notifying subscribers of calls missed by forwarded to number. The present invention relates to services provided by interne protocol multimedia subsystem and more specifically to a system and method of notifying a subscriber about the performance of selected forwarded number. When an call is forwarded to a forward to identity the application server increments a counter in case the call is not answered by the forward to identity. Once this counter reaches a certain threshold, the subscriber is sent a notification of the number of calls missed by selected forward to identity.
1 . A method for notifying a subscriber of calls not attended by a forward to identity in an internet protocol multimedia subsystem network, comprising of
forwarding by said network of a call to a forward to identity received by said subscriber, if said subscriber has call forwarding activated; and
informing said subscriber by said network, if said forward to identity not answering said call.
2 . The method, as claimed in claim 1 , wherein said method further comprises:
incrementing a counter by an application server, on said forward to entity not answering said call, wherein said counter counts number of calls missed by said forward to identity; and
comparing said counter to a threshold by said application server.
3 . The method, as claimed in claim 2 , wherein notifying said subscriber of calls not attended by said forwarded to number, if said counter value exceeds said threshold.
4 . The method, as claimed in claim 2 , wherein notifying said subscriber of calls not attended by said forwarded to number, if said counter value is equal to said threshold.
5 . The method, as claimed in claim 2 , wherein notifying said subscriber by said application server using a call session control function.
6 . An internet protocol multimedia subsystem network comprising at least one means configured for
forwarding of a call to a forward to identity received by said subscriber, if said subscriber has call forwarding activated; and
informing said subscriber, if said forward to identity not answering said call.
7 . The network, as claimed in claim 6 , wherein said network further comprises of an application server, wherein said application server further comprises at least one means configured for
incrementing a counter, on said forward to entity not answering said call, wherein said counter counts number of calls missed by said forward to identity; and
comparing said counter to a threshold.
8 . The network, as claimed in claim 7 , wherein said application server is further configured for notifying said subscriber of calls not attended by said application server, if said counter value exceeds said threshold.
9 . The network, as claimed in claim 7 , wherein said application server is further configured for notifying said subscriber of calls not attended by said application server, if said counter value is equal to said threshold.
10 . The network, as claimed in claim 7 , wherein said application server further is further configured for notifying said subscriber using said call session control function.
11 . An application server in an internet protocol multimedia subsystem network, said application server comprising at least one means configured for
forwarding of a call to a forward to identity received by said subscriber, if said subscriber has call forwarding activated; and
informing said subscriber, if said forward to identity not answering said call.
12 . The application server, as claimed in claim 11 , wherein said application server further comprises at least one means configured for
incrementing a counter, on said forward to entity not answering said call, wherein said counter counts number of calls missed by said forward to identity; and
comparing said counter to a threshold.
13 . The application server, as claimed in claim 12 , wherein said application server is further configured for notifying said subscriber of calls not attended by said forwarded to number, if said counter value exceeds said threshold.
14 . The application server, as claimed in claim 12 , wherein said application server is further configured for notifying said subscriber of calls not attended by said forwarded to number, if said counter value is equal to said threshold.
15 . The application server, as claimed in claim 12 , wherein said application server further is further configured for notifying said subscriber using said call session control function.
