    Abstract: This application relates to the field of communications technologies, and in particular, to a profile download technology. In a profile download method, a primary device obtains an embedded integrated circuit card identifier (EID) of a secondary device, where the EID is used by the primary device to obtain, from a mobile operator server, profile download information that matches the EID; receives the profile download information from the mobile operator server; and sends the profile download information to the secondary device, where the profile download information is used by the secondary device to download a profile from a profile management server, and the profile is installed in an embedded UICC (eUICC) of the secondary device after the download is complete.

    Abstract: A measurement method for a device includes, for each antenna group other than a target antenna group in an antenna array, determining compensation values of the antenna group based on characteristic parameters of the antenna group and characteristic parameters of the target antenna group, and adjusting, based on the compensation values of the antenna group, an electromagnetic wave transmitted by each antenna unit in the antenna group such that electromagnetic waves transmitted by all antenna units in the antenna array have a same phase or amplitude when the electromagnetic waves arrive at a measurement probe of a second device, where the electromagnetic wave is used to measure an over-the-air beam parameter of the first device, and a distance between the first device and the measurement probe is less than a far-field boundary distance.

    Abstract: A system includes: a processor in electrical communication with a data packet network that includes a first network device having a first network node and a second network device having a second network node. The system also includes a non-transitory memory having stored instructions, when executed by the processor, configured to perform acts including: generating a frame denoting a protocol data unit (PDU) to implement at least one OAM function within the data packet network; encapsulating the PDU in a packet having a header; transmitting the packet from the first network node to the second network node. The PDU is a generic PDU (GPDU) for implementing at least one generic OAM (GOAM) function across the first and second network nodes operating different transmission protocols. The header includes GOAM indication information denoting the presence of the GPDU within the packet.

    Abstract: A method and a device for sharing a PCIe I/O device, and an interconnection system are provided. The method includes: determining a shared PCIe I/O device in a PCIe interconnection system; establishing, by using a BAR at a working node, a first mapping relationship between an address of a CSR of the shared PCIe I/O device and an address, used for processing the CSR, in a working node domain. The method also includes establishing, by using an A-LUT fragment at a management node side of the NTB, a second mapping relationship between an address, used for receiving an MSI-X interrupt of the shared PCIe I/O device, in a management node domain and an address, used for processing the MSI-X interrupt, in the working node domain.
