摘要： A time synchronization method and an apparatus are disclosed. The method includes: receiving, by a terminal device, a first time sent by an access network device; obtaining a first transmission delay; obtaining a fourth time based on the first transmission delay and the first time; and synchronizing a time of the terminal device based on the fourth time. In this way, when the terminal device synchronizes the time of the terminal device, the first transmission delay is introduced, so that a time error of air interface transmission can be effectively avoided, and accuracy of time synchronization can be improved. In addition, the time synchronization method has relatively strong applicability, and may be applicable to terminal devices in different states, for example, an idle state, a connected state, and a deactivated state.

摘要： Embodiments of this application provide a method and an apparatus for avoiding failure of transmitting consecutive data packets, and relate to the communications field. The method includes: maintaining, by a first access stratum entity of a transmit end, a transmission status of a previous data packet of the first access stratum entity, where the transmission status includes transmission success, transmission failure, or packet loss. If the transmission status of the previous data packet is transmission failure, the transmit end adjusts a transmission parameter of a current data packet. The method provided in the embodiments of this application ensures that in a data transmission process, a case in which two consecutive application layer data packets both fail to be transmitted does not occur. This improves data transmission reliability.

摘要： This application provides a communication method and a communications apparatus. The communication method includes: determining, by a transmit end device, a first moment, where the first moment is a moment when a receive end device needs to deliver first data to an upper layer of a communications protocol layer of the receive end device; and sending, by the transmit end device, first indication information and the first data, where the first information is used to instruct the receive end device to deliver the first data to the upper layer of the communications protocol layer of the receive end device at the first moment. The receive end device can be supported in determining the first moment based on the first indication information and delivering the first data to the upper layer of the communications protocol layer at the first moment. Therefore, the receive end device can be supported in performing an action corresponding to the first data in the upper layer of the communications protocol layer at the first moment, thereby preventing a transmission latency from affecting execution by the receive end device of an action corresponding to the data.

摘要： The present invention discloses an information transmission method, user equipment, an access network device, and a core network device. The method includes: determining, by user equipment UE when the UE is in an idle state, whether there is to-be-transmitted uplink information; and sending, by the UE, a first request message to a first access network device when the UE determines that there is to-be-transmitted uplink information, where the first request message is a first air interface message for the UE to switch from the idle state to a connected state, and the first request message carries uplink non-access stratum NAS information and air interface identity information that is stored on the UE. According to the information transmission method, the user equipment, the access network device, and the core network device in the embodiments of the present invention, when the user equipment is switched from the idle state to the connected state, by directly carrying the NAS information in the first air interface message, the user equipment can rapidly establish a NAS signaling connection, thereby reducing overheads of air interface signaling.
