Abstract: An intent processing method. A first device sends first information to a second device, wherein the first information indicates impact on at least one KPI when a solution of a first intent is executed. After receiving the first information, the second device may determine the execution suggestion for the first intent based on the first information. The second device sends the information that indicates an execution suggestion for the first intent to the first device.

Abstract: An intent state management method, network element, and system are described. A first network element obtains a first network parameter value corresponding to an intent; and determines, based on the first network parameter value corresponding to the intent, that a condition for achieving the intent is not satisfied. In accordance with the determination, the first network element suspends execution of the intent, sends a first notification message to a second network element, where the first notification message notifies the intent to enter a sleep state; and sets the sleep state to an active state when the condition for achieving the intent is satisfied or the intent is modified. Network resources of the first network element can be saved. When the condition for achieving the intent is satisfied or the intent is modified, the intent enters the active state, so that a state of the intent can be adjusted in time.

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.
