Appl. No.:

09/416054

Inventors:

Li Zhang - Alpharetta GA
Jeffrey P. Cassanova - Hiram GA
Alan R. Blackburn - Woodstock GA
Robert B. Collicott - Alpharetta GA

Assignee:

BellSouth Intellectual Property Corporation - Wilmington DE

International Classification:

H04L 1266

US Classification:

370352, 370410

Abstract:

An Internet Call Waiting-Voice over Internet Protocol (ICW-VOIP) service that uses a service control point and service node of a Public Switched Telephone Network (PSTN), acting as a gatekeeper and bridge respectively, to enable ICW subscribers to answer telephone calls during an internet session without having to disconnect internet access. The primary network components of the ICW-VOIP service comprise a proxy firewall, a service node, and a gateway. When a PSTN call is placed to a subscriber whose line is being used for internet access, the service control point accesses the subscribers internet address from a database and transmits a message over the internet to the subscriber giving the subscriber the option to accept the call as a VOIP call. Once accepted, the subscriber places an H. 323 call through the gateway to the service node.

US Classification:

709227, 709245, 709223, 370352

Abstract:

Systems and methods for providing personalized internet protocol (IP) services to an IP enabled device residing on a local area network (LAN) are disclosed. The systems and methods utilize an access device in communication with an access provider network, and involve communicating a first IP address to the access device, the first address allowing the access device to communicate with a first plurality of IP service devices through an Internet service provider (ISP), and communicating a second IP address to the access device, the second address allowing the access device to communicate with a second plurality of IP service devices in the access provider network. When the access device receives IP traffic from the IP enabled device it determines whether the IP traffic is addressed to one of the second IP service devices. If yes, the IP traffic is forwarded to the one of the second IP service devices with the second address as a return address. Otherwise, the IP traffic is forwarded to the ISP with the first address as the return address.

US Classification:

709219, 709227

Abstract:

Embodiments of the present invention relate to systems for converged service creation and execution. In an embodiment, a system includes an application server and service session manager logic, where the service session manager logic is in communication with the application server. A converged service creation and execution environment messaging bus is in communication with the service session manager logic, and a plurality of service servers are in communication with the converged service creation and execution environment messaging bus.

US Classification:

709226, 709223, 709225, 3703952, 37039521

Abstract:

Quality of Service (QoS) and/or bandwidth allocation is managed in a Regional/Access Network (RAN) that provides end-to-end transport between a Network Service Provider (NSP) and/or an Application Service Provider (ASP), and a Customer Premises Network (CPN) that includes a Routing Gateway (RG). A first subsystem is configured to manage QoS and/or bandwidth allocation for an access session in the CPN. A second subsystem is configured to manage QoS and/or bandwidth allocation for an application flow in the CPN. Thus, the RAN can independently manage QoS, session authentication and/or bandwidth allocation for an access session and for an application flow.

Abstract:

Methods, systems and/or computer program products are provided for managing Quality of Service (QoS) and/or bandwidth allocation in a Regional/Access Network (RAN) having a broadband access server (BRAS) that facilitates differentiated end-to-end data transport between a Network Service Provider (NSP) and/or an Application Service Provider (ASP), and a Customer Premises Network (CPN) that includes a Routing Gateway (RG). In particular embodiments of the present invention, a modify QoS and/or bandwidth allocation message including updated QoS and/or bandwidth information from the NSP and/or ASP is received at the RAN. The BRAS is updated with the QoS and/or bandwidth information and the RG is also updated with the QoS and/or bandwidth information.
