  • Patent number: 11582179
    Abstract: In an example information search method, if a first terminal performs a first search based on a first keyword, and does not obtain a result, the first terminal generates a request for performing a second search, and sends, to a network device, the request for performing the second search. The network device sends a second request to a second terminal. The second terminal performs the second search based on the first keyword, obtains a second search result, and sends the second search result to the first terminal. Through this technique, it can be effectively ensured that a user finds a search result corresponding to the first keyword, and that user privacy is also ensured.

  • Patent number: 8320265
    Abstract: The present invention discloses a method for obtaining an attenuation factor. The method is adapted to process the synthesized signal in packet loss concealment, and includes: obtaining a change trend of a signal; obtaining an attenuation factor, according to the change trend of the signal. The present invention also discloses an apparatus for obtaining an attenuation factor. A self-adaptive attenuation factor is adjusted dynamically by using the latest change trend of a history signal by using the present invention. The smooth transition from the history data to the data last received is realized so that the attenuation speed is kept consistent between the compensated signal and the original signal as much as possible for adapting to the characteristic of various human voices.
