摘要： This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives indication information from a first access network device. The indication information is used to indicate to fall back a capability of the terminal device to a first protocol version. The terminal device communicates, based on the indication information, with the first access network device by using first capability information. A protocol version corresponding to the first capability information is lower than or equal to the first protocol version. In this method, because a network device can explicitly indicate to fall back the capability of the terminal device to the first protocol version, the terminal device can specially reduce the capability, so as to quickly resolve a communication problem caused by incompatibility between the terminal device and the access network device.

摘要： Embodiments of this application disclose a data processing method and a related device, to improve stability and reliability of data transmission. In embodiments of this application, the method includes: If a target buffer that is corresponding to a target priority and that is on a network device reaches a first threshold, the network device sends a pause message to an upstream device, so that the upstream device stops sending a first data packet corresponding to the target priority. If duration in which the network device stops buffering a second data packet is greater than preset duration, and the target buffer falls back below a second threshold, the network device sends a sending resumption message to the upstream device, so that the upstream device sends a third data packet corresponding to the target priority. The second data packet is a data packet that is buffered after the network device sends the pause message and before the network device sends the sending resumption message and that is corresponding to the target priority.

摘要： Embodiments of this application disclose a data processing method and a related device. The method may be applied to the vehicle field. The method includes: A control device receives a first data transmission request sent by a diagnostic device, where the first data transmission request is used to request the control device to receive an upgrade file, the first data transmission request carries a first memory address corresponding to the upgrade file, and the upgrade file is used to upgrade the control device. The control device obtains a first file path corresponding to the first memory address, receives the upgrade file sent by the diagnostic device, and stores the upgrade file into a file to which the first file path points. Therefore, the upgrade file can be downloaded by the diagnostic device under constraint of the UDS protocol.

摘要： This application provides a method and communication apparatus for reporting UE capability information, and a communication system. Through key value learning or at delivery, a UE prestores a key value and an encoded data stream, and records a correspondence between the stored key value and encoded data stream, so that when reporting UE capability information, the UE can directly query the stored key value. If the UE can find a matched key value, the UE directly reports a stored data stream to a network device without performing a complex and time-consuming process such as filtering and encoding, thereby helping reduce a latency in reporting the UE capability information by the UE. In addition, the UE capability information is usually reported when the UE enters a connected state from an idle state. Therefore, due to the reduction in the reporting latency, a connection can be quickly established between the UE and the network device, and a service can be quickly established, thereby improving user experience.

摘要： Embodiments of the present invention disclose a data transmission method. In a process in which a server sends encrypted service data to a terminal device, the server transmits, to an awareness node, application information needed by the awareness node, so that the awareness node can learn of, based on the application information, service information of the encrypted service data transmitted between the terminal device and the server, and accordingly a service awareness system completes a service related to service content. The application information is transmitted in a plaintext manner, and the server does not need to additionally increase an encryption/decryption protocol stack. Data transmission is more convenient and system costs are lower while it is ensured that the service data between the terminal device and the server is encrypted.

摘要： This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives an identifier of a filtering protocol version from an access network device, and then sends first capability information of the terminal device to the access network device based on the filtering protocol version. In this method, the terminal device may report capability information based on the filtering protocol version sent by the access network device. Compared with a manner in which the terminal device directly reports the capability information, this method can effectively reduce a communication problem caused by mismatch between a protocol version supported by the terminal device and a protocol version supported by the access network device and/or a protocol version supported by a core network device.

摘要： This application discloses a network congestion control method, apparatus, device, and system, and a storage medium. The method includes: The first switch receives a target signaling packet that is sent by a second switch in a target network congestion status. The target signaling packet carries flow source information. The first switch sends, based on the target signaling packet, target flow control information to a network device corresponding to the flow source information. The target flow control information is used to indicate flow control. After receiving the target signaling packet that is sent by the second switch in the target network congestion status, the first switch sends the target flow control information to the network device corresponding to the flow source information carried in the target signaling packet, to indicate flow control, suppress a queue backlog on a congestion side, and ensure a low service delay, without affecting a service throughput. In this way, large-scale RoCE networking can be supported, thereby resolving a DCQCN speed control failure problem in a large-scale high-concurrency scenario.
