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 registration method includes sending, by a terminal, a first message to the AMF entity, where the first message includes first information, first network slice selection information, second network slice selection information, and information for requesting to establish a protocol data unit (PDU) session. The first network slice selection information is used by the AMF entity to select a first session management control function (SMF) entity, and the second network slice selection information is used by the AMF entity to select a second SMF entity. The method further includes receiving, by the terminal, a second message from the AMF entity, where the second message includes second information, and the second information includes PDU session establishment accept information.

Abstract: A method for controlling a transmit power of a terminal, and a terminal, where the method and the terminal include, working states of a first antenna and a second antenna may be monitored, and then a transmit power of the first antenna or that of the second antenna may be controlled according to a preset correspondence. Therefore, according to the method and the terminal, a transmit power of an antenna in a working state in the first antenna and the second antenna may be accurately controlled. If the transmit power is less than a standard transmit power, a Specific Absorption Rate (SAR) can be reduced.
