  • Patent number: 7877086
    Abstract: Gathering location information from a first wireless network to determine whether to anchor a communication session in a second wireless network, a mobile node capable of communicating with both the first wireless network and the second wireless network, includes receiving location information from the first wireless network as the mobile node moves through one or more service areas of the first wireless network. It is determined whether a triggering event occurs. If the triggering event occurs, the location information is stored to determine whether to anchor a session in the second wireless network.

  • Patent number: 7844039
    Abstract: 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.

  • Patent number: 7830888
    Abstract: 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.

  • Patent number: 7830891
    Abstract: 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.

  • Patent number: 7797427
    Abstract: 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.

  • Patent number: 7773585
    Abstract: 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.

  • Patent number: 7760639
    Abstract: 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.

  • Publication number: 20100088388
    Abstract: In one embodiment, a method includes identifying a critical time when a current presence state associated with a first client is scheduled to change to a timed presence state. The method also includes generating a first presence document before the critical time, and providing the first presence document to at least a second client. The first presence document has an indication of the current presence state and the timed presence state, and is provided to the second client before the critical time.

  • Publication number: 20090262730
    Abstract: An illustrative intelligent network and method for providing voice telephony over Asynchronous Transfer Mode (“ATM”) and private address translation are provided that can provide significant advantages. The method includes generating an input ATM setup message at the calling party CPE that includes a VToA designator and a called party phone number, extracting information from the input ATM setup message such as the VToA designator and the called party phone number, analyzing the information, designating an ATM address of a called party CPE to be stored in the first parameter of an output ATM setup message, determining if private address translation is needed, designating the ATM address of the called party CPE to be stored in a first instance of the second parameter of the output ATM setup message, designating an ATM address of an egress ATM edge switch to be stored in the first parameter of the output ATM setup message, and generating an output ATM setup message.

  • Patent number: 7607138
    Abstract: Event services provided between domains include receiving a first subscription request to receive an event state of an event source. A view associated with the first subscription request is determined. A notify message is sent that reflects a first defined view into the event state of the event source that corresponds to the first subscription request. A second subscription request is received to receive the event state of the event source. A view associated with the second subscription request is determined. It is determined if the first defined view corresponds to the second subscription request.
