  • Publication number: 20190132308
    Abstract: A server receives a certificate signing request and onboarding information for an applicant device, and identifies a customer associated with the applicant device based on an applicant device identifier and a database identifiers associated with customers. The device determines a registered device associated with the customer is a trusted device, a location trust value for the applicant device based on a geolocation proximity between the applicant device and the trusted device, and an environment trust value for the applicant device based on a proximity in a network topology between the applicant device and the trusted device. The device further determines a trust score for the applicant device based on the location trust value and the environment trust value, and sends a signed certificate to the applicant device over the network when the trust score for the applicant device exceeds a threshold.

  • Publication number: 20180352484
    Abstract: In an example, a wireless communication system and apparatuses thereof are described. In an example long-term evolution (LTE) network, a first base station hands over a connection to a second base station. The first base station may be a (femto) home eNodeB (HeNB) or (macro) eNodeB. The second base station may also be a HeNB or eNodeB connected to a different gateway. The first base station may send “Handover Request” on an X2 connection, identifying the gateway that the second base station is connected to as the correct gateway. After sending a “Handover Request Acknowledgement,” the second base station correctly establishes a tunnel to a connected gateway device.

  • Patent number: 9031560
    Abstract: A method includes sending a message from a first base station to another entity in a radio network. The message includes one or more indications one or more conditions have been met. The one or more conditions include one or both of: a duration the user equipment is connected to a first cell served by the first base station, prior to handover from the first cell to a second cell served by a second base station, is less than a threshold; or the signal strength of the second cell as measured by the user equipment and reported to the first base station is better than a signal strength of the first cell for a threshold duration of time. The entity may receive the message, e.g., and use the message to determine whether to effect changes to the radio network. Apparatus, program products, and software are also disclosed.

  • Publication number: 20120276900
    Abstract: A method for handing off handset in a mobile communication network that defines at a base station (110) an adjusted handover boundary (106) different from a default handover boundary (104) between the base station (110) and a different base station (116). Handover adjustment parameters can be conveyed (120) within messages to user equipment (UE) (112) within range (124) of the base station. The handover adjustment parameters can provide specifics for handover permitting the user equipment (UE) (120) receiving the messages to perform handover operations (166) in accordance with the adjusted handover boundary (106) instead of the default handover boundary (104). The handover adjustment parameters can increment the cell individual offset (CIO) (212) when adjusting for “too late” (210) handover conditions. The handover adjustment parameters decrease the cell individual offset (CIO) (222) when adjusting for “too early” (220) handover conditions.

  • Patent number: 6978317
    Abstract: A method and apparatus for a mobile device (104) to register with a private home agent (106), the method comprising the steps: generating (304) and sending (306) a registration request (700) addressed in the public network (110) to a public address of the private home agent, the request (700) adapted to initiate registration of the mobile device with the private home agent. The mobile device is located within a public network, but belongs to a private network (102) and has a private address. The private home agent is located in the private network and has both a private address and a public address. The request also indicates that the mobile device is in the public network. In preferred form, the request includes an extension (704) that provides this indication. The home agent receives and processes the request, then forwards an appropriate reply (800) back to the mobile device.
