Abstract: This application discloses a communication method, a device, and a communication system, and relates to the field of communication technologies, to reduce power consumption of a terminal device while ensuring user experience. In this application, a proxy server may be indicated, based on a sensed use status of the terminal device, to perform downlink sending of an application message by using a strategy adapted to the sensed use status. For example, when the terminal device is in a not-in-use state, the proxy server may send a downlink application message to the terminal device by using a specific strategy based on a message type of the application message, for example, forward an application message of a second type in real time, or cache application messages of a first type and then jointly forward the application messages.

Abstract: A network hotspot control method and a mobile terminal to diversify shared-hotspot control manners, where the method includes receiving, by a first mobile terminal, a hotspot setting operation, setting a control policy of a network hotspot, where the control policy includes at least a file type control policy receiving, by the first mobile terminal, a network service request from a second mobile terminal that has established a coupling to the first mobile terminal, and controlling, by the first mobile terminal, the network service request according to the control policy.

Abstract: An icon display method automatically displays a service icon on a desktop of an electronic device, so that a user directly uses a service item by using the service icon, thereby reducing user operations and improving user experience. An electronic device automatically determines a first service item in a first application; displays a first icon on a display interface of the electronic device, where the first icon corresponds to the first service item; and displays an interaction interface of the first service item in response to an operation performed on the first icon.
