Abstract: In a V2X communication method, a first communication device obtains an identification set including one or more identifications, where a risk of collision between a moving subject corresponding to each identification and a first moving subject corresponding to the first communication device meets a preset condition. When a channel busy ratio is greater than a first threshold, the first communication device sends configuration information including the identification set to a second communication device. When the channel busy ratio is greater than a second threshold, the first communication device transmits a V2X message to the second communication device through the standby communication connection channel, where the second threshold is greater than the first threshold.

Abstract: Example electric appliance identification methods and apparatuses are provided. One example method includes obtaining, by a power line communication (PLC) device, a first noise signal in a circuit. The PLC device can then obtain first data based on the first noise signal, where the first data is used to describe a time-frequency feature of the first noise signal. The PLC device can then obtain, based on an electric appliance identification model and the first data, an electric appliance identification result corresponding to the first noise signal, where the electric appliance identification model is obtained based on a signal including a second noise signal of at least one known electric appliance.

Abstract: A method and apparatus for implementing multicast. When a multicast source performs route advertisement, route update is performed on a cross-DC integrated device, and a received device identifier and a received AS number are replaced with a device identifier and an AS number that are of the integrated device. In this way, when a multicast user joins the multicast source, each network device in the network can trace the multicast source based on a received route, and determine a multicast path that is from the multicast source to the multicast user. Therefore, it is possible to accurately perform, in a NG MVPN, cross- DC multicast on traffic of the multicast source.

Abstract: A circuit includes: a first electrical interface including a first pin, a resistor module, an alternating current signal source, a voltage detection module, and a controller. One end of the resistor module is electrically connected to the first pin. The alternating current signal source is electrically connected to the other end of the resistor module, and configured to generate an alternating current detection signal. The voltage detection module is connected to the first pin, and configured to detect a maximum voltage value and a minimum voltage value that are on the first pin within a period of the alternating current detection signal. The controller is separately connected to the alternating current signal source and the voltage detection module, and configured to, when a difference between the maximum voltage value and the minimum voltage value is less than a first threshold, determine that water enters the first electrical interface.

Abstract: A method for data transmission in a system including a first base station controller (BSC) and a first media gateway (MGW) is provided. The first MGW receives from the first BSC an internet protocol (IP) packet with an encoded voice payload encapsulated therein. The encoded voice payload is obtained by the first BSC by removing a Transcoder and Rate Adaptation Unit (TRAU) encapsulation from data received from a base transceiver station (BTS). The first MGW determines a codec type of the encoded voice payload is the same as a codec type adopted by a second BSC connected to the first MGW or is the same as a codec type adopted by a second MGW connected to the first MGW. The first MGW sends the encoded voice payload to the second BSC or the second MGW after the determination.
