Abstract: This application relates to a communication method and device. The method includes receiving a first traffic flow and sending the first traffic flow by using at least two QoS flows. The first traffic flow corresponds to an application transmitted by using the at least two QoS flows. For example, different QoS flows may be used to transmit data packets of different importance degrees. In this way, the data packets of different importance degrees can be separately controlled, for example, sending of a more important data packet is preferentially ensured, to improve transmission reliability of these data packets, and ensure service experience of a user.

Abstract: A method including a first network element receiving first information reported by a first terminal device. The first information is used to indicate parameter information of an exception when the first terminal device accesses a first cell. The first network element determines configuration information based on the first information. The configuration information includes configuration information for accessing the first cell. The first network element sends the configuration information.

Abstract: Embodiments of this application provide a transmission path switching method and apparatus. When a transmission path is switched, a currently used data transmission path is not directly switched from a first transmission path to a second transmission path after the second transmission path is configured, but after it is further determined that a first condition is met, the currently used data transmission path is switched from the first transmission path to the second transmission path, to avoid data interruption in a process of switching a data transmission path of an application from the first transmission path to the second transmission path. This improves use smoothness of the application.

Abstract: An application processor sends a TCP packet to the modem, where the TCP packet is used by the modem to generate a wireless protocol data packet corresponding to the TCP packet, so that the modem sends the wireless protocol data packet to a base station. The application processor receives first status information from the modem, where the first status information is status information of the wireless protocol data packet or status information of the TCP packet. The application processor determines, based on the first status information, whether the TCP packet is successfully sent to the base station. If the TCP packet is successfully sent to the base station, the application processor starts a retransmission timer corresponding to the TCP packet. If the TCP packet is not successfully sent to the base station, the application processor sends the TCP packet to the modem again.

Abstract: A connection management method includes: accessing, by UE, a network using a first base station, where the UE is in an RRC inactive state; accessing, by the UE, a network using a second base station, where the second base station does not support the RRC inactive state; and sending, by the UE, a first request message to a first core network entity using the second base station, so that the first core network entity releases a connection to the first base station based on the first request message.
