Abstract: A linear prediction residual energy tilt-based audio signal classification method and apparatus, where the method includes: determining, according to voice activity of a current audio frame, whether to obtain a linear prediction residual energy tilt of a current audio frame of the current audio frame and store a frequency spectrum fluctuation of the current frame in a frequency spectrum fluctuation memory, where the linear prediction residual energy tilt denotes an extent to which an audio signal's linear prediction residual energy changes as a linear prediction order inscreases; updating, according to whether the audio frame is percussive music or activity of a historical audio frame, frequency spectrum fluctuations stored in the frequency spectrum fluctuation memory; and classifying the current audio frame as a speech frame or a music frame according to statistics of some or all of effective data of the frequency spectrum fluctuations stored in the frequency spectrum fluctuation memory.

Abstract: A electronic device includes a USB Type-C interface, a switching circuit, a first signal path, and a second signal path. The USB Type-C interface is configured to connect to a USB Type-C device. The switching circuit is connected to the USB Type-C interface, the first signal path, and the second signal path. When the USB Type-C interface is connected to the USB Type-C device, the first signal path is connected to the USB Type-C interface through the switching circuit, and a level of a first pin of the USB Type-C interface is a first level. When the USB Type-C interface is disconnected from the USB Type-C device, the second signal path is connected to the USB Type-C interface through the switching circuit, and a level of the first pin is a second level. The first level is greater than the second level.

Abstract: A voice service processing method and an apparatus are provided. The method includes: receiving, by a base station, voice configuration indication information from user equipment (UE), where the voice configuration indication information is used to indicate at least one voice configuration supported by the UE; and configuring, by the base station, a voice transmission scheme for the UE based on the voice configuration indication information. The UE can initiate a voice service on a 5G network, and a high-quality and convenient voice service can be provided for a user.

Abstract: The present application discloses an optical switch, including a first optical waveguide, a second optical waveguide, and a first heater, where a place at which a distance between the first optical waveguide and the second optical waveguide is the smallest is a junction; the first heater is adjacent to the third optical sub-waveguide; and there is a first dielectric material between the first heater and the third optical sub-waveguide, and there is a second dielectric material between the third optical sub-waveguide and the fourth optical sub-waveguide, where a thermal conductivity of the first dielectric material is greater than a thermal conductivity of the second dielectric material. The optical switch has advantages such as high heating efficiency, a small quantity of heaters, and simple control.

Abstract: The present invention relates to a system, a device, and a method for customizing a user-defined network. The system includes a gateway and a mobile network element. The gateway is configured to receive a user-defined network request, request, according to the user-defined network request, an invocation of a communications service corresponding to the mobile network element to establish or modify the user-defined network, and return an invocation result. The user-defined network request includes definition information of an MBB communications service resource required by the MBB application service. The mobile network element is configured to implement invocation of the corresponding communications service.

Abstract: An image processing method, including: obtaining image data of a photographed original image, and obtaining ambient infrared intensity I that is used when the original image is photographed; obtaining infrared image data corresponding to I according to a preset correspondence between tested infrared intensity and infrared image data; obtaining corrected image data according to the image data of the original image and the infrared image data corresponding to I; and obtaining a corresponding corrected image according to the corrected image data, and outputting the corrected image.

Abstract: The present invention discloses a method for acquiring a PON port association relationship. An OLT where a standby PON port is located receives a protection packet from an optical network unit, parses the protection packet to obtain an identifier of an active PON port carried in the packet, and acquires an association relationship between the active PON port and the standby PON port according to an identifier of the standby PON port receiving the protection packet. When the present invention is implemented, the OLT where the standby PON port is located can acquire an association relationship between an active PON port and a standby PON port, and determine, according to the association relationship, whether the protection packet is valid or acquire, according to the association relationship, configuration information of the active PON port.

Abstract: The present invention discloses a method for processing LMP packet carrying a control message, which includes: receiving the LMP packet carrying a control message from a peer LMP node, determining whether a state of a control channel is an available state according to the LMP packet, and updating or resetting a HelloDeadInterval timer if the control channel is in the available state. When the control channel is in the available state, the processed LMP packet is sent to the peer node, a new LMP packet carrying the control message is generated and sent to the peer node, and a HelloInterval timer is updated or reset. The present invention further provides a LMP processing unit and a LMP packet processing node.
