摘要:
Some embodiments provide a method, system, and apparatus for transparently backing-up information from a mobile device to distributed devices having storage capabilities. As the mobile device comes within communication range of one or more of the trusted partner devices, information from the mobile device is backed up, in segments or portions, on the one or more distributed partner devices. Information backed-up in one partner device may be transferred to another partner device for storage. A centralized master server may also maintain a list of the locations (e.g., partner devices) where backup information is maintained for the mobile device. When requested to do so by a user, the centralized server can retrieve and consolidate the backup information for the mobile device.

A scheme is provided for determining the geographical location of an active IP device coupled to an IP network. A network path to the user device is obtained to identify a last hop device having a known first geographical location. A last leg distance between the last hop device and the user device is calculated. The last leg bandwidth, propagation time, and propagation speed are also characterized to more accurately determine the last leg distance. By combining the known first geographical location and the distance of the last hop device and user device, a geographical location for the user device is obtained. To improve the accuracy of the geographical location of the user device, multiple last hop devices with known geographical locations are employed to obtain multiple geographical areas for the user device. The intersection or overlap of these geographical areas indicates a refined geographical location of the user device.

One feature provides a method for encoding geolocation information into a next-generation internet protocol (IP) address, such as IPv6, to facilitate distribution of geolocation information among networked devices. A request for an IP address assignment is received from a network device. The geographical location for the network device is obtained. An IP address is assigned or generated that includes the geographical location. The assigned IP address is then provided to the network device. By encoding the geolocation information of a first network device into the IP address assigned to the first network device, other network devices are able to readily obtain the geographical location of the first network device. This method propagates geolocation information for network devices as part of the IP address, thus avoiding the need for separate geolocation distribution messaging. As the network device moves, its IP address is changed to update its geographical location information.

A portable self-contained node apparatus establishes a connection to a host apparatus having one or more peripheral devices connected directly thereto. The node apparatus is configured to view the one or more peripheral devices while being unaware of the host apparatus, and to act as a master device interacting directly with the one or more peripheral devices.

A close-loop quality of service system is provided that collects real-time network performance indicators at the physical, data link and network layers. Using those indicators, the system dynamically controls the network traffic in order to achieve improved performance according to the priority and policy defined by a data user or system/network administrator. Several features of this quality of service system includes (1) dynamic maximum bandwidth reallocation, (2) dynamic maximum packet sizing, (3) adaptive policing, and/or (4) real-time link status feedbacks to make more efficient use of available bandwidth and adjust to transmission requirements.

A wireless device provides location data concerning an object by use of geolocation in order to provide distance tracking and local location techniques in order to provide local tracking. The geolocation and local location techniques may be implemented at the same time or individually, reconfigurable on demand, in both the tracking and tracked devices. The tracked wireless device includes a wireless communication circuit capable of communication with a multiuser wireless subscriber network. A geolocation reading circuit provides GPS or similar location data and is capable of obtaining geolocation data concerning the object. A local locating device parses local location data, and an indication is provided of geolocation based on the geolocation data, and is further responsive to the local location data which is used to modify the geolocation data with the local location data.

A mobile access point is disclosed. The mobile access point includes a terminal module configured to provide one or more terminal functions for use by a user, the one or more terminal functions including a voice or data communications application, and a gateway module configured to provide one or more gateway functions for use by at least one client device, the one or more gateway functions including providing the at least one client device access to a computer network, and a processor configured to execute the terminal module and the gateway module to effectuate their corresponding functions.
摘要:
A scheme is provided for distributing reference geographical locations on a network. Geolocation information is integrated or associated with one or more network infrastructure devices to permit them to serve as reference points for the rest of the network. A reference geographical location associated with a network infrastructure device may be broadcast by the network infrastructure device over a network. Alternatively, other network devices may request reference geographical location from a network infrastructure device or obtain it from a network-accessible database that stores such geolocation information. Other network devices can then use the one or more reference geographical locations to determine their own geographical location. By allowing existing network devices to take advantage of the geolocation capability of its “neighboring” network devices, this scheme provides a convenient way to deliver geolocation to many network devices.
摘要:
A method and apparatus for downloading a hyper text transfer protocol (HTTP) web page over a wireless link that couples a modem to a gateway. A transmission control protocol (TCP) link is opened between the gateway and the modem. A HTTP uniform resource identifier (URI) is received at the modem from a web browser, where the HTTP URI corresponds to the HTTP web page of an origin server. The TCP link is configured well before the web browser provides the URI. The HTTP URI is sent to the gateway. An Internet protocol (IP) address is determined for a domain name indicated in the HTTP URI by the gateway. The HTTP web page is retrieved by the gateway using the Internet, without the modem requesting it. The HTTP web page is transmitted to the satellite modem. Objects referenced in the HTTP web page are accessed similarly to the HTTP web page, but objects can also be accessed in parallel. In some cases, bandwidth is scaled for the TCP link according to loading of the modem.
