Communication system performing communications concerning requests for requesting commands

A communication system comprising an information processing apparatus and a mediation apparatus,

• wherein the mediation apparatus is configured to communicate with a device via a local network,
• wherein the information processing apparatus is configured to communicate with Internet and communicate with the mediation apparatus through firewall, the information processing apparatus including:
• a memory storing correlation information which correlates each of event IDs with one of a first command and a second command, the first command being for the device and the second command being for the mediation apparatus;
• and a first control device configured to perform:
• transmitting event information according to a series of procedures which is initiated by the mediation apparatus and enables the mediation apparatus to receive information from the information processing apparatus through the firewall, the event information including a plurality of event IDs and specifying an order of the plurality of event IDs;
• receiving a command transmission request from the mediation apparatus through the firewall, the command transmission request including an event ID included in the event information;
• determining one of the first command and the second command as a target command for transmission on a basis of the event ID included in the command transmission request by using the correlation information;
• and
• transmitting the target command to the mediation apparatus through the firewall,
• wherein the mediation apparatus includes a second control device configured to perform:
• initiating the series of procedures enabling the mediation apparatus to receive information from the information apparatus through the firewall;
• receiving the event information from the information processing apparatus through the firewall;
• transmitting separately a plurality of command transmission requests including respective ones of the plurality of event IDs included in the event information to the information processing apparatus through the firewall so that the plurality of event IDs is transmitted to the information processing apparatus according to the order specified by the event information;
• receiving the target command from the information processing apparatus through the firewall;
• in response to receiving the first command as the target command, transmitting to the device via the local network a device command which the device is capable of interpreting on a basis of the first command;
• and
• in response to receiving the second command as the target command, performing a second-command-dependent instruction based on the second command.

A non-transitory computer readable storage medium storing a set of program instructions comprising first program instructions executed by an information processing apparatus, and second program instructions executed by a mediation apparatus, the information processing apparatus being configured to communicate with Internet and communicate with the mediation apparatus through firewall, the mediation apparatus being configured to communicate with a device via a local network, wherein the second program instructions comprise:

• transmitting to the information processing apparatus through the firewall a first request for requesting transmission of a first command for the device;
• transmitting to the information processing apparatus through the firewall a second request for requesting transmission of a second command for the mediation apparatus;
• in response to receiving the first command, transmitting to the device via the local network a device command based on the first command;
• and
• in response to receiving the second command, performing a second-command dependent instruction,
• wherein the first program instructions comprise:
• in response to receiving the first request, transmitting the first command to the mediation apparatus through the firewall;
• and
• in response to receiving the second request, transmitting the second command to the mediation apparatus through the firewall.

A non-transitory computer readable storage medium storing a set of program instructions comprising first program instructions executed by an information processing apparatus, and second program instructions executed by a mediation apparatus, the mediation apparatus being configured to communicate with a device via a local network, the information processing apparatus being configured to communicate with Internet and communicate with the mediation apparatus through firewall, the information processing apparatus including a memory storing correlation information which correlates each of event IDs with one of a first command and a second command, the first command being for the device and the second command being for the mediation apparatus, wherein the first program instructions comprise:

• transmitting event information according to a series of procedures which is initiated by the mediation apparatus and enables the mediation apparatus to receive information from the information processing apparatus through the firewall, the event information including a plurality of event IDs and specifying an order of the plurality of event IDs;
• receiving a command transmission request from the mediation apparatus through the firewall, the command transmission request including an event ID included in the event information;

• receiving the target command from the information processing apparatus through the firewall;
• in response to receiving the first command as the target command, transmitting to the device via the local network a device command which the device is capable of interpreting on a basis of the first command;
• and
• in response to receiving the second command as the target command, performing a second-command-dependent instruction based on the second command.
