Abstract: A voice wakeup method and a device are provided. The method includes: receiving, by a third-party device, wakeup messages sent by at least two electronic devices, where the wakeup message includes wakeup keyword energy information used to indicate a wakeup keyword energy value, and the wakeup keyword energy value; normalizing wakeup keyword energy values based on ambient sound energy and/or sound collection capabilities of devices, to obtain at least two normalized wakeup keyword energy values; and based on the at least two normalized wakeup keyword energy values, sending a wakeup permission instruction to a first electronic device in the at least two electronic devices, and sending a wakeup prohibition instruction to another electronic device other than the first electronic device, where a normalized wakeup keyword energy value of the first electronic device is a maximum value. This helps improve accuracy of waking up a device nearby in a multi-device scenario.

Abstract: Apparatuses and methods for determining if a computer program is malware and to which malware class it belongs to. In the method, the behaviour of a computer program is traced by observing the activity of the program. Behaviour sequences comprising API-calls or similar activity of a computer program are then provided into a classifier for classifying the computer program. From the outcome of the classifier, a classification result and the portions relevant to decision can be provided to a person for further confirmation.

Abstract: Embodiments of this application provide a volume adjustment method and device, and a system. The method includes: A first terminal device sends a first playback request to a server, where the first playback request carries a model of the first terminal device and an identifier of the first audio. The server determines a first volume value of the first audio based on the identifier of the first audio and the model of the first terminal device. The server determines, based on the first volume value and a preset volume threshold of the first terminal device, a first volume gain. The first terminal device determines, based on the first volume gain and a currently set second volume value, a first target volume value. The first terminal device adjusts volume of playing the first audio to the first target volume value.

Abstract: In a power adjustment method for reducing energy consumption of a network system, a network management server collects a network indicator of a cell in the network system. The network management server uses the network indicator to establish a prediction model, and uses the prediction model to predict energy consumption and quality of service of the network system based on transmit power of the cell. The network management server then adjusts the transmit power of the cell based on the prediction model to meet a constraint condition of the quality of service and an energy consumption optimization objective of the network system.
