Abstract: This application discloses an information exchange method and apparatus. In the method, a terminal device transmits attach request information to a core network device, receives attach accept information of the core network device, where the attach accept information includes a first integrity check code; the terminal device obtains a second integrity check code based on the attach accept information; and the terminal device obtains, if the first integrity check code is the same as the second integrity check code, a third integrity check code based on encrypted attach complete information, and transmits encrypted attach complete information to which the third integrity check code is added to the core network device. This reduces data exchange procedures, reduces an amount of data of exchanged information, and reduces a time consumed in an information exchange process performed between the terminal device and the core network device.

Abstract: A synchronization method and an apparatus are provided to meet a time precision requirement of an industrial factory in a scenario in which a mobile network is connected to an Ethernet network. In an embodiment, a first device determines seventh timestamp information by using timestamp information of receiving and sending packets in a mobile network, so that a second device calculates a time offset between the first device and the second device based on the seventh timestamp information and time points of receiving and sending packets in an Ethernet network, to perform time synchronization. In the method, impact of a transmission delay between the first device and the second device can be avoided, so that a time precision requirement of an industrial factory can be met in a scenario in which the mobile network is connected to the Ethernet network.

Abstract: Example communication methods and apparatus in a wireless network are described. One example communication method includes establishing dual connections to a first access network device and a second access network device by a terminal device. A connection that is between the terminal device and the first access network device and that is included in the dual connections is a radio resource control (RRC) connection. The terminal device receives first configuration information sent by the first access network device. The first configuration information includes signaling radio bearer (SRB) configuration information of the second access network device and a trigger condition for using the SRB configuration information. When the trigger condition is met, the terminal device uses the SRB configuration information of the second access network device to establish an RRC connection to the second access network device.
