Device cooperation method, apparatus, and system

A device cooperation method, wherein the method is applied in an intermediate device, the intermediate device pre-establishes communication connections to one primary device and a plurality of secondary devices, and the method comprises:

• receiving, by the intermediate device, a to-be-processed event sent by the primary device;
• recognizing, by the intermediate device, an event type and event information of the to-be-processed event;
• obtaining, by the intermediate device, device information of each of the plurality of secondary devices;
• obtaining, by the intermediate device, a device filtering condition corresponding to the event type, wherein the device filtering condition is used to indicate device information of a secondary device matching the event type;
• determining, by the intermediate device based on the device information of each of the plurality of secondary devices, a first secondary device that satisfies the device filtering condition;
• and
• sending, by the intermediate device, the event type and the event information to the first secondary device when the intermediate device determines that a data type of the event information is a data type supported by the first secondary device.

A primary device, wherein the primary device pre-establishes communication connections to a plurality of secondary devices, the primary device comprises a processor and a memory, the memory is configured to store instructions, and the processor is configured to execute the instructions stored in the memory;

• and
• the processor is configured to:
• receive a to-be-processed event;
• recognize an event type and event information of the to-be-processed event;
• obtain device information of each of the plurality of secondary devices;
• obtain a device filtering condition corresponding to the event type, wherein the device filtering condition is used to indicate device information of a secondary device matching the event type;
• determine, based on the device information of each of the plurality of secondary devices, a first secondary device that satisfies the device filtering condition;
• and
• send the event type and the event information to the first secondary device when determining that a data type of the event information is a data type supported by the first secondary device.
