  • Patent number: 8037418
    Abstract: A wireless communication device stores a system GUI configuration file and a downloaded service provider GUI configuration file, each of which contains a text name checksum value that is calculated using the text names of the GUI parameter data stored either the system GUI configuration file or the service provider GUI configuration file. The text name checksum values are based on the text names of the GUI parameter data. After the download operation is complete, a text name checksum comparator program compares the downloaded text name checksum value to the initial text name checksum value in the system GUI configuration file. If the two text name checksum values do not match, the downloaded service provider GUI configuration file is rejected.

  • Patent number: 8019991
    Abstract: There is disclosed a security device for use in a wireless network comprising a group of base stations that communicate with numerous mobile stations. The security device prevents an unprovisioned one of the mobile stations from accessing an Internet protocol (IP) data network through the wireless network. The security device comprises a first controller for receiving from the unprovisioned mobile station an IP data packet comprising an IP packet header and an IP packet payload. The first controller replaces the IP packet header with a replacement IP packet header containing an IP address of a selected provisioning server of the wireless network. The first controller selects the provisioning server by selecting the IP address in the replacement IP packet header according to a load spreading algorithm.

  • Patent number: 7673300
    Abstract: A segmented linker for generating from an original binary file an upgraded binary file suitable for replacing a copy of the original binary file installed in a target device. The segmented linker receives as inputs a plurality of objects, the original binary file, and a memory map input file associated with a target device. The segmented linker preserves in the upgraded binary file at least some of the spatial locality of reference of code in the original binary file. The segmented linker further receives as an input a linker guideline file that defines the layout of objects having spatial locality of reference in the original binary file. The segmented linker uses the linker guideline file to limit the propagation of cascading address references in the upgraded binary file.

  • Patent number: 7529779
    Abstract: A method of generating a composite delta file based on the differences between an original file and an upgraded file. The method comprises the steps of: 1) segmenting the original binary file into segments of size N; 2) segmenting the upgraded binary file into segments of size N; 3) detecting a first set of differences between a first segment from the original binary file and a first segment from the upgraded binary file; and 4) generating a first delta file from the detected first set of differences. The method further comprises the steps of: 4) detecting a second set of differences between a second segment from the original binary file and a second segment from the upgraded binary file; and 5) generating a second delta file from the detected second set of differences. The first and second delta files are combined to form the composite delta file.
