A function resource configuration method includes receiving, by a wearable device, a distribution request sent by a first terminal, where the distribution request is used to request the wearable device to distribute a first function resource of the wearable device to the first terminal, and where the first function resource is already occupied by a second terminal. The wearable device determines, based on the distribution request, whether to allow the first terminal to use the first function resource. If the wearable device allows the first terminal to use the first function resource, the wearable device sends a notification message to the first terminal that instructs the first terminal to use the first function resource.
