Abstract: A profile download method includes a primary device obtaining 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. The primary device 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 where the profile is installed in an embedded UICC (eUICC) of the secondary device after the download is complete.

Abstract: A video playing method, a device, and a system are provided. The method includes: receiving, by a VR device, a first-resolution VR video stream of a first viewing angle and a second-resolution VR video stream of a full viewing angle that are sent by a server, where the first resolution is greater than the second resolution; playing an image of the first viewing angle by using the VR video stream of the first viewing angle; when determining that the viewing angle changes, playing an image of a current viewing angle by using the first or both of the VR video stream of the full viewing angle and the VR video stream of the first viewing angle; sending, to the server, viewing angle information that carries a parameter for indicating a changed-to second viewing angle; receiving a first-resolution VR video stream of the second viewing angle sent by the server.

Abstract: A path computation method and a related device are disclosed. The method includes: a second network device receives path requirement information and a recomputation condition that are sent by a first network device; the second network device first obtains by means of computation a path meeting a requirement according to the path requirement information, and sends description information of the path meeting the requirement to the first network device; then the second network device constantly determines whether the recomputation condition is met; and when the recomputation condition is met, the second network device performs path recomputation, and sends description information of a path obtained by means of recomputation to the first network device. Therefore sensitivity for triggering path recomputation can be improved and a quantity of communication messages between network devices can be reduced.

Abstract: A method for generating configuration information includes: a network control unit receives a virtual machine association message, where the VM association message includes an identifier of a first VM and an identifier of a first virtual built-in network element (NE), where a state of the first VM changes and the first virtual built-in NE detects that the state of the first VM changes; and the network control unit determines first information according to the identifier of the first VM, where the first information includes at least one of: a first forwarding entry, a location information mapping entry of the first VM, and a first network policy. According to the method, a network control unit determines first information according to an identifier of a first VM whose state changes and whose identifier is included in a VM association message, network configuration efficiency and network performance are improved.

Abstract: Embodiments of the present invention disclose a code channel detecting method and a related device and a communication system. In the solutions provided by the embodiments of the present invention, whether a DPA code channel is in an active state is determined with multiple thresholds based on a first reference value and a third reference value, or based on a first reference value, a second reference value and a third reference value. This mechanism takes multiple possible false determination situations into consideration, thereby ensuring a code channel correct detection rate in multiple interference scenarios and relatively reducing a false alarm rate.

Abstract: A call record synchronization method includes detecting, by a first terminal, an input operation for requesting to display a call record. The method further includes, after the first terminal detects the input operation, displaying, by the first terminal, a merged call record, where the merged call record is a call record obtained after merging of a call record of the first terminal and a call record of a second terminal. The merged call record includes a device identifier of the first terminal and/or a device identifier of the second terminal.
