Patent number: 7711098Abstract: A call is forwarded by connecting the call between an originating location and a forwarding location without connecting the call through a terminating location. The originating location is associated with a calling party. The terminating location is associated with a dialed number. The terminating location and the forwarding location is associated with the called party. A bill for the call is apportioned between the calling party and the called party. The bill portion for the calling party is a function of the originating location and the terminating location. The bill portion for the called party is a function of the terminating location and the forwarding location.Type: GrantFiled: February 11, 2005Date of Patent: May 4, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: Charles Robert Kalmanek, Jr., William Todd Marshall, Partho Pratim Mishra, Douglas M Nortz, Kadangode K.

Patent number: 7492886Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. In particular, the network resources for the call are reserved based on a reservation request. Prior to the reservation request being made, one or more operational parameters for the call are established by a gate controller and sent to a network edge device or other routing entity associated with one of the parties. An identifier, illustratively a so-called gate identification, is sent to that party. Thereafter the routing entity receives the identifier from the associated party in, for example, the aforementioned resource reservation request. The routing entity is able to use the identifier to determine the one or more parameters established for the call and to thereupon cause the call to be established—including the reserving of resources—in a way that is consistent with the one or more parameters.Type: GrantFiled: March 28, 2007Date of Patent: February 17, 2009Assignee: AT&T Intellectual Property II, L.P.Inventors: Charles Robert Kalmanek, Jr., William Todd Marshall, Partho Pratim Mishra, Douglas M.

Publication number: 20090044242Abstract: A method of providing video content is disclosed that includes receiving video content associated with a television stream from a video source at a server of a video distribution network. The method also includes sending a primary multicast video stream corresponding to the video content to a video distribution network entity via an Internet Protocol (IP) network. The primary multicast video stream is associated with a first bandwidth. Further, the method includes sending a secondary multicast video stream to the video distribution network entity via the IP network. The secondary multicast video stream is associated with a second bandwidth. The primary multicast video stream and the secondary multicast video stream are accessible to a set-top box device via the video distribution network entity in response to a channel change request that indicates the television stream.Type: ApplicationFiled: August 8, 2007Publication date: February 12, 2009Applicant: AT&T Knowledge Ventures, LPInventors: Kadangode Ramakrishnan, Charles Robert Kalmanek, JR., Robert Duncan Doverspike, William C.

Patent number: 7289490Abstract: Gates for a call between a calling party and a called party are coordinated. A timer associated with a first gate opened at an originating network edge device is initiated. A first gate open message is sent from the originating network edge device to the terminating network edge device. The first gate at the originating network edge device is released if the timer expires before at least one from the group of: (1) an acknowledgment based on the sent first gate open message is received from the terminating network edge device, and (2) a second gate open message is received at the originating network edge device from the terminating network edge device after the terminating network edge device has opened a second gate associated with the called party.Type: GrantFiled: June 22, 2004Date of Patent: October 30, 2007Assignee: AT&T Corp.Inventors: Charles Robert Kalmanek, Jr., William Todd Marshall, Partho Pratim Mishra, Douglas M.

Patent number: 7035410Abstract: The broadband telephony interface is provisioned by receiving information authenticating a provisioning server, establishing a communication channel between the user and the provisioning server over which is transmitted authorization information from the user to the provisioning server, and encrypting and transmitting a cryptographic key associated with the user to the provisioning server. The cryptographic key can be a symmetric key or a public key corresponding to a private key stored in the broadband telephony interface. The cryptographic key can be utilized to generate other keys which are utilized to secure communication channels for the telephony service. The broadband telephony interface advantageously can be implemented as untrusted hardware or software that is installed by a customer.Type: GrantFiled: March 1, 2000Date of Patent: April 25, 2006Assignee: AT&T Corp.Inventors: William A.
