Control system and control method, method and apparatus for processing information, information processing terminal and method thereof, storage medium, and program
First Claim
1. A control system including an information processing apparatus and an information terminal connected with each other via a network, the system comprising:
- the information terminal including;
a processor;
a requesting unit configured to, in a state in which a device is connected with the information terminal, request the information processing apparatus to establish communication via the network;
a receiving unit configured to receive a packet, including a command for controlling the device, and a script indicating processes to be performed to complete the command, from the information processing apparatus via communication established in response to the request issued by the requesting unit; and
a control unit configured to control the device in accordance with the command included in the packet received by the receiving unit, the information processing apparatus including;
an establishment unit configured to establish communication performed via the network between the information processing apparatus and the information terminal, in response to the request issued by the information terminal; and
a transmission unit configured to transmit the packet to the information terminal from the information processing apparatus after the communication with the information terminal is established by the establishment unit,wherein the command includes information indicating whether, when the information terminal fails to perform a process to be performed in order to complete the command, an other process should be continued in accordance with a following command, part of the processes in the script for controlling the device are performed in the information terminal, and after the processes in the script are performed, a response packet, including responses from the device to the information terminal, is transmitted to the information processing apparatus.

Abstract
A client (such as a PC, portable telephone, PDA, electrical appliances), to which a device such as a IC card is connected, starts a handshake protocol to request a server to start communication. When communication is established via the handshake protocol, the initiative of communication is transferred to the server, and the state changes into a neutral state. In this neutral state, a control packet including a particular number of messages and a finished message is transmitted from the server to the client. If the client receives the control packet, the client performs a process according to the messages included in the control packet. This makes it possible to remotely control a device via a network in a highly reliable and efficient manner.
