  • Patent number: 8724625
    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.

  • Patent number: 7069344
    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.

  • Patent number: 7058022
    Abstract: A method of configuring a network access device having a network address associated with an extra-regional service provider with a new network address associated with a regional access network provider, where the network access device is connected to a regional access network connected to a plurality of extra-regional service networks. The method includes receiving a request from the network access device requesting the release of access to the extra-regional service network, sending a response from the regional access network, and receiving a network address change request using a configuration protocol. In another aspect of the invention, the network address associated with an extra-regional service provider is automatically released when a regional access network server fails to receive a request to renew the network address lease, and a new network address associated with the regional access network is assigned to the network access device.

  • Patent number: 6753887
    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.

  • Publication number: 20010049737
    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: displaying a plurality of service providers on a graphical user interface; in response to a subscriber selection on the graphical user interface, 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.
