  • Patent number: 9392441
    Abstract: The present invention discloses a method and apparatus for controlling updates to a mobile device consisting of checking a ROM installation package and storing the check data, or encrypting a ROM installation package and storing said encrypted ROM installation package. The stored check data is used to check a ROM installation package or to decrypt a stored encrypted ROM installation package when updating a mobile device. If it is verified to be correct or to be decryptable, the verified or decrypted ROM installation package is installed. If it is verified to have errors or to be undecryptable, the installation of the ROM installation package is terminated. The present invention reduces the risks associated with the destruction or disclosure of data when mobile devices are lost.

  • Patent number: 8305982
    Abstract: A method for assigning signature sequences for E-HICH channel which may avoid the unbalanced situation brought about by the codeword assignment is provided, wherein the use of User Equipment (UE) signature sequences on Enhanced Dedicated Channel Hybrid Automatic Repeat Request Acknowledgement Indicator Channel (E-HICH) is equalized, so as to drive the average detection performance toward equity for different UEs to detect their respective signature sequences on E-HICH channel, and to reduce the average false detection rate for the respective UE on the feedback information transmitted thereto. The method includes: firstly, assigning a E-HICH logical signature sequence index r for each UE; then, converting the logical signature sequence index r into a physical signature sequence index r? varying with time by using a random permutation function; and after that, assigning a signature sequence corresponding to the physical signature sequence index r? to the respective UE.
