发明名称 Information processing device, subsystem, information processing method, and recording medium storing information processing program
摘要 An information processing device capable of performing external communication through a communication device for performing communication includes a subsystem arranged between the communication device and a main unit of the information processing device including a central processing unit and an operating system. The subsystem temporarily stores communication data between the communication device and the central processing unit when the central processing unit is in a power source turned-off state or a suspended state, and the subsystem transfers the communication data between the communication device and the central processing unit when the central processing unit is in a power source turned-on state. Accordingly, external communication is enabled without altering the connection manager of the OS even when the subsystem is placed between the communication device and the OS.

主权项 1. An information processing device capable of performing external communication through a communication device for performing communication, the information processing device comprising: a subsystem arranged between the communication device and a main unit of the information processing device including a central processing unit and an operating system, wherein the subsystem temporarily stores communication data between the communication device and the central processing unit when the central processing unit is in a power source turned-off state or a suspended state, and the subsystem transfers the communication data between the communication device and the central processing unit when the central processing unit is in a power source turned-on state, the subsystem includes a pseudo responsive unit configured to make a pseudo response, which indicates that the external communication between the main unit and an external carrier network outside of the information processing device has been established, to the main unit, as a substitute for a response by the communication device and as a response to a request of an establishment of the external communication from the main unit, when the external communication with the subsystem has been already established, when the subsystem receives from the main unit a request of disconnecting the established external communication between the main unit and the external carrier network, the pseudo responsive unit makes another pseudo response, which indicates that the established external communication between the main unit and the external carrier network has been disconnected, to the main unit, as a substitute for a response by the communication device, still maintaining the established external communication with the subsystem, and the subsystem further includes: a communication data buffer unit configured to temporarily store communication data between the communication device and the main unit;a communication data copy unit configured to copy and store communication data stored in the communication data buffer unit; anda specific port data extraction unit configured to determined whether there is any communication data that corresponds to a specific port of the subsystem in the communication data stored in the communication data copy unit, and to extract the communication data that corresponds to the specific port of the subsystem from the communication data copy unit.
