               1. A system, comprising: 
            a first device; and 
                a second device, wherein the first device and the second device are user terminal devices; 
                wherein the first device is configured to perform: 
                generating a notification; 
                  determining that the notification needs to be sent to another device for prompting, the determining being based on a notification type of the notification and based on a service type of a service corresponding to the notification, wherein the notification type indicates that the notification is a screen-off notification for the determining that the notification needs to be sent to another device for prompting; and 
                  sending a first message, wherein the first message indicates the first device generates the notification; and 
                wherein the second device is configured to: 
                receiving the first message, and generate a prompt on the second device for executing a task corresponding to the notification in a third device; and 
                  sending, from the second device to the third device, a second message without executing the task corresponding to the notification on the second device for viewing details of the notification or processing the notification generated by the first device and in response to receiving a user's input corresponding to the prompt, the second message requesting the third device to start execution of the task corresponding to the notification to show the details of the notification or process the notification, 
                wherein the second message further indicates a media access control (MAC) address of the third device, wherein the first device selects the second device for prompting based on the second device being suitable for displaying brief information about the notification but not suitable for displaying the details of the notification or processing the notification, and wherein the first device selects the third device for the execution of the task corresponding to the notification based on the third device having a better display capability and a better interaction capability than the second device.
