  • Patent number: 8402143
    Abstract: A proxy is in communication with an internet protocol network and a mobile operator network. The proxy receives first communications from access points via the internet protocol network, transmits content from the first communications to the mobile operator network, receives second communications from the mobile operator network, and transmits content from the second communications to the access points via the internet protocol network. The proxy may perform operations based on the first and second communications received from either the access points, or from the mobile operator network. The operations performed by the proxy may include modifying the communications, saving certain information regarding the communications, performing authentication, encryption, or decryption of the communications, determining a destination for the communications, or sending the communications to a destination.

  • Patent number: 8176327
    Abstract: A method includes sending a first authentication challenge from an authenticator to an access terminal, and receiving, at the authenticator, a first return message from the access terminal that includes an identifier of the access terminal and a response to the first challenge. A second authentication challenge is sent from the authenticator to the access terminal, in which the second authentication challenge is determined by an authentication server based in part on the identifier of the access terminal previously received along with the response to the first challenge. The authenticator receives a second return message from the access terminal that includes a response to the second authentication challenge.

  • Patent number: 8078165
    Abstract: Information is received identifying a geographic location of an access point in a radio access network. Access information is assigned and communicated to the access point, and the access information and the geographic location information is communicated to an access terminal. The access terminal identifies the access point as a preferred access point, including its geographic location. The access terminal receives information identifying its own geographic location, and when the access terminal is near the access point, the access point is used to access the network. The access point receives information identifying its geographic location and communicates the geographic location information to a configuration server. The access point receives access information from the configuration server and provides access terminals access to the network using the access information.
