Abstract: This application provides example data communication methods and apparatuses. One example method includes, after a terminal device is handed over to a first base station and the first base station receives data sent by a switch, generating, by the first base station, second indication information. The second indication information is used to indicate a second base station to stop receiving the data sent by the switch. The first base station can then send the second indication information to the second base station. After receiving a feedback acknowledgment of the second base station for the second indication information, the first base station can then send, to the terminal device, the data sent by the switch.

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: 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: This application relates to the field of communications technologies. Specifically, this application provides a scheduling method. In the method, when a terminal needs to send service data of an ultra-reliable and low latency communications service, the terminal sends a scheduling request to a base station, where the scheduling request carries buffer information in a buffer state report sent by the terminal to the base station in an original scheduling procedure. Therefore, compared with an existing scheduling procedure, in the scheduling method provided in this application, no buffer state report needs to be sent to the base station, thereby reducing steps of the scheduling procedure, and reducing a scheduling latency. To achieve an inventive concept of reducing the steps of the scheduling procedure, this application further provides a scheduling method for simplifying steps of a scheduling procedure. In addition, to ensure practical application and implementation of the scheduling method, this application further provides a corresponding scheduling device.

Abstract: A downlink scheduling data monitoring method, a downlink scheduling data sending method, and an apparatus are provided. The method includes: starting a timer; and after it is determined that the timer expires, monitoring, by using a first discontinuous reception DRX monitoring cycle, downlink scheduling data sent by a base station, where duration of the first DRX monitoring cycle is in a unit of minute or hour. After it is determined that the timer expires, the downlink scheduling data is monitored by using the first DRX monitoring cycle whose duration is in a unit of minute or hour. In this way, not only power consumption is reduced, but also the downlink scheduling data can be monitored.

Abstract: Methods, systems, and apparatus for clock synchronization are provided. In one aspect, a clock synchronization method includes: receiving, by a terminal and from an access network device, information about N clock domains, determining, by the terminal, M clock domains that are associated with the terminal and that are in the N clock domains, and separately performing, by the terminal, clock synchronization with clock sources of the M clock domains based on information about the M clock domains. Information about a clock domain includes first time information and a clock domain number of the clock domain. The first time information includes a time of a clock source of the clock domain when the access network device sends the information about the clock domain. The clock domain number identifies the clock domain. N is an integer greater than 1, and M is an integer greater than 1.

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.
