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 quality of service (QoS) resource allocation method and apparatus, where the method includes receiving service information from then, sending a QoS resource request message that carries the service information to a policy and charging rules function (PCRF) corresponding to the terminal, where the QoS resource request message requesting the PCRF to allocate a QoS resource to a terminal service, and receiving a request response message from the PCRF indicating whether the QoS resource is successfully allocated to the terminal service. The terminal can recognize the service information of the terminal service, and a specific implementation of sending, to the PCRF, the service information of the terminal service recognized by the terminal is put forward such that accuracy of a policy formulated by the PCRF is improved.

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.

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: Embodiments of the present invention relate to a call record synchronization method, a cloud platform, and a terminal. The method includes: detecting, by a first terminal, an input operation for requesting to display a call record; and 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, and the merged call record includes a device identifier of the first terminal and/or a device identifier of the second terminal. According to the embodiments of the present invention, a user can use the merged call record to identify call answering or making statuses on a plurality of terminals, without querying a plurality of call records. This improves user experience.
