Patent number: 7844039Abstract: Methods are disclosed for providing prepaid telephony service via an Internet protocol (IP) network system. A first method provides controlling at least one media agent or call routing station/switch of an IP network system for allowing and/or blocking call media streams from traversing through the media agent. A second method provides directing all signaling messages transmitted by a signaling agent or station and all media packets transmitting voice and data communications through at least one common device within the IP network system. The methods further provide for continuously monitoring a subscriber's account balance and terminating the prepaid telephony service if the account balance is less than a predetermined amount.Type: GrantFiled: June 9, 2004Date of Patent: November 30, 2010Assignee: Verizon Business Global LLCInventor: Steven R.

Patent number: 7830888Abstract: A method for combining Internet protocols in a Differentiated Services model environment is described. The Session Initiation Protocol (SIP) and Common Open Policy Service (COPS) are combined together to provide methods of setting up a session and tearing down a session, while maintaining Authentication, Authorization, and Accounting (AAA) policies. The Open Settlement Policy (OSP) is also combined with SIP and COPS. This combination provides for an interchange of parameters between session setup, teardown, authorization, policy, Quality of Service (QoS), and usage reporting.Type: GrantFiled: May 16, 2005Date of Patent: November 9, 2010Assignees: Verizon Communications Inc.Inventor: Steven R.

Patent number: 7830891Abstract: A method and system for providing quality of service in an IP telephony session between a calling party and a called party establishes a high quality of service ATM virtual circuit for the session between first and second devices, each of the devices having ATM capability and IP capability. The first and second devices provide bidirectional translation between IP media and ATM media. The system transports IP media for the session between the calling party and the first device, and between said called party and a second device. The virtual circuit transports ATM media for the session between the first and second devices. An intelligent control layer provides IP and ATM signaling to set up the session.Type: GrantFiled: October 26, 2006Date of Patent: November 9, 2010Assignee: Verizon Business Global LLCInventors: John K. Gallant, Steven R. Donovan

Patent number: 7797427Abstract: A system and method for applying a communication feature extension includes facilitating an exchange of requests between an originating endpoint and a terminating endpoint using a first identifier associated with the originating endpoint and a second identifier associated with the terminating endpoint. A modified request is received during the exchange. The modified request includes a new identifier representing a selected one of a modified first identifier and a modified second identifier, and an extension providing information about handling the modified request. The extension included in the modified request is determined and applied.Type: GrantFiled: December 13, 2005Date of Patent: September 14, 2010Assignee: Cisco Technology, Inc.Inventors: Steven R.

Patent number: 7773585Abstract: A method for signaling an Integrated Messaging System (IMS) on an Internet Protocol (IP) based network to deposit a message, including the steps of sending a Session Initiation Protocol (SIP) SIP INVITE request to the IMS indicating a message deposit action; receiving a corresponding SIP message from the IMS agreeing to participate in the message deposit action; and sending an SIP acknowledge message to the IMS confirming receipt of the corresponding SIP message; and depositing the message in a destination mailbox. A method of signaling an IMS on an IP based network to retrieve a deposited message, the method including the steps of sending a SIP INVITE request to the IMS indicating a message retrieval action; receiving a corresponding SIP message from the IMS agreeing to participate in the message retrieval action; sending an SIP acknowledge message to the IMS confirming receipt of the corresponding SIP message; and retrieving the deposited message from a mailbox corresponding to known account information.Type: GrantFiled: December 4, 2006Date of Patent: August 10, 2010Assignee: Verizon Business Global LLCInventor: Steven R.

Patent number: 7760639Abstract: A system and method for handling network overload includes receiving one or more requests, wherein an originating client originates the one or more requests. It is determined if a network element processing the one or more requests is overloaded. If the network element is overloaded, a pushback message is generated. The pushback message is sent with request gapping information to a previous hop in a network, wherein the previous hop is one or more network elements operable to route the one or more network requests to the network element processing the one or more requests.Type: GrantFiled: November 29, 2005Date of Patent: July 20, 2010Assignee: Cisco Technology, Inc.Inventors: Steven R.
