  • Patent number: 7856553
    Abstract: A platform discrimination indication register is stored in a wireless network card. This register holds a platform discrimination indication that indicates whether the wireless network card can be used to transfer data with notebook computers or whether the wireless network card is restricted to transferring data from a personal digital assistant or defined set of restricted devices. The platform discrimination indication can be upgraded using a key value obtained from at Internet site. This key value is limited to a specific wireless network card because of the use of a unique electronic I.D. An Internet site encrypts the electronic I.D. to produce the first key, such as a platform activation key (PAK). This first key is then decrypted at the personal data device in order to obtain a unique calculated I.D. value. If the calculated I.D. value matches the electronic I.D.

  • Patent number: 7827604
    Abstract: The present invention provides a solution in which a script containing general security parameters and access policies in a file is placed on an appropriate internal server. The location of the script may then be stored on an external server. When an end-user within the organization decides to purchase a wireless network device, he may attach it to his existing computer. The computer then may retrieve the security file location from the external server, retrieve the security file from the internal server using the security file location, and program the security file into the wireless device.

  • Publication number: 20100124191
    Abstract: Provided is a method and apparatus for facilitating push communication from a first network to a target device of a second network, the second network comprising a packet service network such as a GPRS core network. A private IP address, usable for addressing the target device when the packet service network is in an activated state with respect thereto, is retained. Upon receipt of a first message from the first network, indicative of a push communication for the target device, the packet service network is disposed into the activated state, and a second message, addressed to the private IP address, is transmitted. The second message may be generated by a NAT configured to implement micro-port forwarding. The second message may be generated by a representative device of the second network, configured to receive the first message via a NAT in response to a query generated by the representative device.

  • Patent number: 7668231
    Abstract: The system includes a modem unit with a standardized form factor and standardized connector. The modem unit can be connected to a phone shell personal digital assistant and for other data units. Connected to the phone shell, the modem unit transmits voice data. Connected to the personal digital assistant or other data device, the modem unit transfers data. By having a modem unit that can usable both for voice and data, a single cellular transceiver can be used for both voice and data without requiring a wired connector. Additionally the standardized form factor and connector allows a second modem unit, having a second type of cellular connection, to be used in place of the first modem unit. The other type of cellular connection can be a different communication standard.
