Abstract: Example encoding/decoding methods, communication apparatus, and systems are provided. One example encoding method includes encoding first data by using an encoding model, to obtain N pieces of encoded data, where N is an integer greater than 2. De-correlation is performed on the N pieces of encoded data to obtain N pieces of de-correlated encoded data, where a part or all of the N pieces of de-correlated encoded data may be for determining second data, the second data is for restoring third data, and the third data is the first data, or an approximation degree between the third data and the first data is greater than a specified threshold The N pieces of de-correlated encoded data are sent.

Abstract: A data input method and apparatus, and user equipment are provided. The method includes: when it is determined that an operation of a user on the user equipment UE is not performed in a preset display area, deliver an event corresponding to the operation to a first operating environment for processing, where the preset display area runs in a second operating environment of the UE, and the second operating environment has a higher security level than the first operating environment. This can better improve security of an event generated when the user operates a program that runs in a Normal World of the user equipment, and can directly operate an event that runs in the Normal World.

Abstract: The present invention provides method and apparatus for power management of mobile devices and associated mobile devices. The method for power management of mobile devices includes acquiring a predefined battery power level variation ?n of the mobile device and its corresponding usage time t1 if the mobile device uses the power-saving functions; acquiring the same battery power level variation ?n of the mobile device and its corresponding usage time t2 if the mobile device does not use any power-saving function; and determining an extended usage time of the mobile device ?t=t1?t2, and notifying the user of the mobile device the extended usage time. By determining the extended usage time and notifying the user of the extended usage time, the user of the mobile device can have a better understanding of the usage state of the mobile device after adopting the power-saving functions and therefore an improved user experience.
