Abstract: A computer software application running on a wireless communication device determines whether an application scenario is urgent or nonurgent, and determines whether the user state is interest, uninterested or absent. The application sends the application scenario and the user state to a wireless networking device. The wireless networking device determines the user roles of different wireless communication devices. It further adjusts priorities of data packets destined to the wireless communication device based on the application scenario, the user state and the user role when downlink to the wireless communication device is congested. The priority is decreased when the application scenario is unurgent, the user role is a listener, and the user state is uninterested or absent.
