International Classification:

G09G 500

US Classification:

345764, 345733, 345962, 709219, 709227

Abstract:

Client software may be used in conjunction with services offered by several entities such as network service providers. A user interface of the client software presents brand indicia relating to the network service provider that is currently being used by the software. The software is configured by selecting entities with which the software will be used. Once the entities are selected, an instruction server is queried to determine the location of branding data to be presented to the user, and a branding data server is queried to retrieve the branding data. The brand indicia are presented to the user according to the branding data each time the corresponding entity is accessed.

International Classification:

H04L 12/66

US Classification:

370352

Abstract:

A method of configuring a network access device connected to an access network connected to a plurality of service networks, the network device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a second subscriber of services of either the first service provider, or a second service provider provided by a second service network. The method comprises the steps of: sending a request from the network access device to the access network with user credentials for the second subscriber requesting access to the first service provider or a change to the second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol. In this manner, a second network address allocated to the second subscriber of services of either the first or second service providers is assigned to the network access device to enable the network access device to communicate data packets to the service network providing the selected service.

International Classification:

H04L 12/28
H04L 12/56

US Classification:

370392, 370401

Abstract:

A network architecture () provides Voice over Internet Protocol (VoIP) service as well as multimedia and Internet web-based applications while implementing features common in a traditional telecommunications network. In response to an incoming call dialed to an IP endpoint (), the network will process the call, and in particular, convert the call, if in not already in a VoIP format, to such a format, while mapping signaling associated with the call into a compatible format. The VoIP call is then routed to the IP endpoint. In the event that the call requires an associated multimedia or Internet-web-based application, the network will initiate the application. Processing of the incoming call may require accessing of a common database to acquire a location routing number for the call destination. To afford dynamic addressing of the IP endpoints, each may be referenced by a corresponding Universal Resource Locator (URL) (or other indirect mapping) associated with the IP address of the endpoint.

US Classification:

709250, 709221, 709223, 709249, 725111

Abstract:

A method of configuring a network access device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a subscriber of services of a second service provider provided by a second service network, wherein the network access device is connected to an access network connected to a plurality of service networks. The method comprises the steps of: sending a request from the network access device to the access network requesting a change to a second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol. In this manner, a second network address allocated to the subscriber of services of the second service provider is assigned to the network access device to enable the network access device to communicate data packets to the service network providing the selected service. In one preferred embodiment of the invention, the subscriber is authenticated by a service activation system coupled to the access network prior to initiating the configuration protocol.

Abstract:

A network that supports VPNs is enhanced to allow users in one VPN to communicate with users in another VPN in the course of executing a predefined application, such as VoIP. This capability is achieved dynamically by enabling a device that can communicate with the network elements that operate to normally prohibit inter-VPN communication to direct those network elements to enable such communication, at least for the purposes the purposes of specific applications.
