  • Patent number: 8364784
    Abstract: Embodiments of the present invention provide a method, system and apparatus for internally initialized, profile-driven data transfer and propagation. In one embodiment, a data transfer and propagation method can include receiving a request from a pervasive device to upload data to a registration server. The method also can include locating a default entry within a profile for the pervasive device and storing the data in a default location for the registration server as specified by the default entry. Finally, the method can include determining from the request whether or not to propagate the data to other registration servers, and responsive to a determination to propagate the data, propagating the data to other registration servers specified in the profile.

  • Patent number: 7929993
    Abstract: A mobile device includes first identification circuitry and second identification circuitry. The first identification circuitry is associated with a first network and the second identification circuitry is associated with a second network. The mobile device simultaneously registers itself with the first and second networks using the first and second identification circuitry, respectively. The first and second identification circuitry may each comprise subscriber identity modules. The mobile devices handle outgoing and incoming calls based on user preferences. The user may override the preferences for selected calls.

  • Publication number: 20080250478
    Abstract: Public access to a network is provided through wireless access points, which may simultaneously support secured network access; in preferred embodiments, the access points are routers (such as “WiFi” routers). Accordingly, a router is configured with a public access profile (or profiles), which may be selectively enabled or disabled. When enabled, the router sends out an identifier that can be used to associate a client device with a public (i.e., unauthenticated) access path through the router to a network. The router also sends out a conventional identifier that can be used to associate another client device with a secured (i.e., authenticated) access path through the router, where the public and secured access paths are usable simultaneously by clients of the router.
