Systems, methods, and computer readable media for triggerless call redirection with release
First Claim
1. A method for providing triggerless call redirection with release, the method comprising:
- at a communications node in a telecommunications network;
intercepting a call setup signaling message that is associated with a call for which a first circuit-switched bearer path has been reserved and that contains information identifying a subscriber;
determining, using the information identifying the subscriber, whether call redirection information exists for the subscriber, wherein the call redirection information comprises one of call offloading information, switching office cutover information, and advanced routing information;
andin response to determining that the call redirection information exists, sending a release message for releasing the first circuit-switched bearer path and selecting a second bearer path based on the call redirection information associated with the subscriber.

Abstract
Systems, methods, and computer readable media for triggerless call redirection with release are disclosed. According to one aspect, the subject matter described herein includes a method for providing triggerless call redirection with release. The method includes, at a communications node in a telecommunications network, intercepting a call setup signaling message that is associated with a call for which a first circuit-switched bearer path has been reserved and that contains information identifying a subscriber. The information identifying the subscriber is used to determine whether call redirection information (call offloading information, switching office cutover information, and/or advanced routing information) exists for the subscriber. If call redirection information exists for the subscriber, a release message for releasing the first circuit-switched bearer path and selecting a second bearer path based on the call redirection information associated with the subscriber is sent.

17. A method for providing triggerless call redirection with release, the method comprising:
at a communications node in a network having a circuit-switched portion and a packet-switched portion; intercepting a call setup signaling message that is associated with a call for which a first circuit-switched bearer path has been reserved, the message containing information identifying a subscriber; determining, using the information identifying the subscriber, whether call redirection information exists for the subscriber; and in response to determining that the call redirection information exists, sending a release message for releasing the first circuit-switched bearer path and selecting a second bearer path based on the redirection information associated with the subscriber. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)

33. A system for providing triggerless call redirection with release, the system comprising:
-
a communications node in a telecommunications network for intercepting a call setup signaling message that is associated with a call for which a first circuit-switched bearer path has been reserved and that contains information identifying a subscriber; and a triggerless call redirection module, operatively associated with the communications node, for determining, using the information identifying the subscriber, whether call redirection information exists for the subscriber, wherein the call redirection information comprises one of call offloading information, switching office cutover information, and advanced routing information, and, in response to determining that the call redirection information exists, sending a release message for releasing the first circuit-switched bearer path and selecting a second bearer path based on the call redirection information associated with the subscriber. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A system for providing triggerless call redirection with release, the system comprising:
-
a communications node in a network having a circuit-switched portion and a packet-switched portion, for intercepting a call setup signaling message that is associated with a call for which a first circuit-switched bearer path has been reserved, the message containing information identifying a subscriber; and a triggerless call redirection module, operatively associated with the communications node, for determining, using the information identifying the subscriber, whether call redirection information exists for the subscriber, and, in response to determining that the call redirection information exists, sending a release message for releasing the first circuit-switched bearer path and selecting a second bearer path based on the redirection information associated with the subscriber. - View Dependent Claims (50, 51, 52, 53)

65. A computer readable medium having stored thereon computer-executable instructions that when executed by the processor of a computer perform steps comprising:
-
intercepting a call setup signaling message that is associated with a call using a first circuit-switched bearer path originating at the switching point and that contains information identifying a subscriber; determining, using the information identifying the subscriber, whether call redirection information exists for the subscriber, wherein the call redirection information comprises one of call offloading information, switching office cutover information, and advanced routing information; and in response to determining that the call redirection information exists, sending to the source of the call setup signaling message a release message for releasing the first circuit-switched bearer path and selecting a second bearer path based on the call redirection information associated with the subscriber.

-
intercepting a call setup signaling message that is associated with a call in a telecommunications network having a circuit-switched portion and a packet-switched portion and for which a first circuit-switched bearer path has been reserved, the message containing information identifying a subscriber; determining, using the information identifying the subscriber, whether call redirection information exists for the subscriber; and in response to determining that the call redirection information exists, sending a release message for releasing the first circuit-switched bearer path and selecting a second bearer path based on the redirection information associated with the subscriber.
