Abstract: Aspects of the disclosure provide a terminal device that includes an interface circuitry and a processing circuitry. The interface circuitry is configured to interface the terminal device to a network, and transmit and receive signals to/from a server and other terminal devices via the network. The server provides service functionality to users who are registered with the server in a service network. The terminal device is utilized by a first user who is registered in the service network, and is associated with one or more friend users in the service network. The processing circuitry is configured to cause the interface circuitry to send a first application request to a second terminal device that is utilized by a friend user, receive a first response that is generated based on a first input on the second terminal device in response to the first application request, and receive a processing result of the first application request that is determined by the server based on the first response.
