摘要： A method includes that a terminal receives first indication information from a network device, where the first indication information is used for early data transmission, and the first indication information includes slot aggregation information of a physical uplink shared channel PUSCH in a random access procedure; and the terminal performs early data transmission based on the first indication information. Slot aggregation of a PUSCH is used to implement early data transmission of a large data packet.

摘要： A data transmission method and apparatus are provided. The method includes: A first access network device receives a first paging message from a core network device, where the first paging message includes a first security parameter. The first access network device sends a second paging message to a terminal device, where the second paging message includes a first random access preamble index that is ciphered and/or integrity protected by using the first security parameter. The first access network device receives a first random access preamble from the terminal device, and if the first random access preamble is a random access preamble indicated by the first random access preamble index, obtains downlink data of the terminal device. The first access network device sends the downlink data to the terminal device.

摘要： Embodiments of this application provide a handover method, a terminal device, and a network device. The method includes: obtaining, by a first terminal device, first identification information, where the first identification information includes identification information of at least one second terminal device; and performing, by the first terminal device, handover of the first terminal device and the at least one second terminal device based on the first identification information, where the handover is handover from a first network device to a second network device. According to the embodiments of this application, impact of signaling on a network side caused by simultaneous handover of a large quantity of terminal devices is reduced, and a service interruption time during handover is reduced, thereby effectively supporting simultaneous handover of a plurality of terminal devices.
