Abstract: A non-isolated DC/DC converter includes a magnetic material, a switching transistor, and a capacitor, where the switching transistor and the capacitor form charging and discharging loops of the non-isolated DC/DC converter; the magnetic material is located inside a printed circuit board PCB of the non-isolated DC/DC converter; the magnetic material is located in the charging and discharging loops of the non-isolated DC/DC converter; and the magnetic material provides a magnetic circuit for the charging and discharging loops of the non-isolated DC/DC converter. To reduce a loss caused by an inductor, a discrete inductor is no longer disposed in the non-isolated DC/DC converter provided in this application; instead, only a magnetic material is disposed inside the PCB, so that a loop between the magnetic material and another component forms a magnetic circuit, to provide a magnetic flux, and implement a function of the inductor. Therefore, inductor disposition is reduced.

Abstract: The disclosure provides communication methods and apparatuses. One example method includes receiving, by a first network device, a first message from a second network device, where the first message includes network slice configuration information. The network slice configuration information is used to indicate a maximum data rate provided by each of n network slices for a terminal device, and n is an integer greater than or equal to 1. In response to the received first message, the first network device sends a second message to the second network device.

Abstract: A handover method includes receiving a handover requirement message from a source access network device, and sending a handover request message to the target access network device. The handover requirement message includes an identifier of a session of a terminal device. The session is to be handed over from the source access network device to a target access network device. The handover request message includes first single network slice selection assistance information (S-NSSAI). A first network slice of the target access network device that corresponds to the first S-NSSAI serves the session. The first S-NSSAI is determined based on second S-NSSAI and the first network slice supported by the target access network device, and the second S-NSSAI is of a second network slice of the source access network device and that corresponds to the identifier of the session.

Abstract: Embodiments of the present invention propose a communication method. The communication method includes: obtaining, by a base station, DRB configuration information, where the DRB configuration information is used to determine a mapping relationship between serving cells and DRBs used to carry data of different service types; and sending the DRB configuration information to a terminal, so that the terminal communicates with the base station in a serving cell corresponding to a DRB. The embodiments of the present invention further disclose a base station and a terminal to which the communication method is applied.

Abstract: Examples in this application provide a communication method and a communications apparatus. One example communication method includes determining to deactivate or activate a first synchronization signal and physical broadcast channel block (SSB), and sending a first request message to a second network device. Specifically, the first request message carries first indication information for indicating the first SSB, and when the first SSB is an SSB in the first network device, the first request message requests the second network device to update a state of the first SSB, and the second network device maintains information about at least one SSB in the first network device, or when an active first SSB is an SSB in the second network device, the first request message requests the second network device to activate the first SSB, and the first network device maintains information about at least one SSB in the second network device.

Abstract: The present disclosure discloses example wireless network communication methods and network devices. One example method includes sending a first message to a second network device by a first network device, where the first message includes measurement object information of the first network device. A second message sent by the second network device is received by the first network device, where the second message includes indication information or measurement result information of the first network device, and the indication information indicates whether an inter-system unnecessary handover of a terminal device occurs. The first network device determines, based on the second message, whether the inter-system unnecessary handover of the terminal device occurs.
