Methods and systems for providing triggerless intelligent network (in) screening services based on call setup messages
First Claim
Patent Images
1. A system for providing triggerless access to intelligent network services in a communications network, the system comprising:
- (a) a triggerless screening service routing node for determining whether received messages require call screening processing and for diverting the messages that require call screening processing from their original destinations; and
(b) a message processing platform (MPP) operatively associated with the triggerless screening service routing node for receiving the diverted messages, performing at least one call screening action on each of the diverted messages, modifying each message to indicate results of the call screening action and forwarding each modified message to a destination node.

Abstract
Method and systems for providing triggerless screening services include a triggerless screening service routing node and a message processing platform. The triggerless screening service routing node identifies call setup messages that require one or more call screening services and diverts the messages to a message processing platform. The message processing platform performs at least one screening action on the call setup messages and modifies the messages to include the type and result of the screening action.

20. A method for providing triggerless screening services in a communications network, the method comprising:
-
(a) receiving a call setup message;
(b) determining whether the call setup message requires call screening processing;
(c) in response to determining that the call setup message requires call screening processing, diverting the call setup message to a message processing platform;
at the message processing platform;
(d) performing at least one screening action on the call setup message;
(e) modifying the call setup message to identify the type and result of the screening action; and
(f) forwarding the call setup message to a destination node. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method for providing triggerless screening services in a communications network, the method comprising:
-
(a) receiving a call setup message;
(b) identifying the call setup message as an ISUP message and, in response, forwarding the ISUP message to a database;
(c) performing a lookup in the database based on one or more parameters in the call setup message to identify a screening service required for the call setup message;
(d) performing the screening action on the call setup message;
(e) modifying the call setup message to include results of the screening action; and
(f) forwarding the call setup message to a destination node. - View Dependent Claims (42, 43, 44, 45, 46, 47)
