Management system and control method

1. A management system including a device management server, an information processing terminal and a relay apparatus,

wherein the device management server is configured to manage a plurality of devices using device information of the plurality of devices,

wherein the relay apparatus is configured to monitor the plurality of devices that exist in a customer network and have a function for accepting cross domain communication,

wherein the device management server comprises at least one memory storing first instructions and at least one processor executing the first instructions causing the device management server to:

receive an acquisition request for the device information from the information processing terminal; and

send, in response to the received acquisition request and to the information processing terminal, response data including information for displaying the device information and script information, wherein the script information includes a command to cause the information processing terminal to perform cross domain communication for checking whether access to a web server implemented on a device is permitted, and

wherein the information processing terminal comprises at least one memory storing second instructions related to a web browser and at least one processor executing the second instructions causing the information processing terminal to:

perform the cross domain communication to a web server of the relay apparatus by execution of the command included in the script information in the response data, wherein domain information corresponding to the device management server as a source of the response data is set in data which is transmitted in the cross domain communication;

receive, from the web server of the relay apparatus, data including a determination, by the relay apparatus, using the domain information; and

generate, when the determination included in the received data indicates a permission, a link for access to a web server implemented on a device monitored by the relay apparatus from among a plurality of devices corresponding to device information displayed based on the information included in the response data,

wherein, when the determination included in the received data does not indicate the permission, the link for the access to the web server implemented on the device monitored by the relay apparatus is not generated.

2. The management system according to claim 1 , wherein if the information processing terminal does not exist in the customer network and data in response to the performed cross domain communication is not received by the information processing terminal, the link for the access to the web server implemented on the device monitored by the relay apparatus is not generated.

3. The management system according to claim 1 , wherein the response data further includes an identifier (ID) of the relay apparatus, and

wherein if the determination indicates the permission and the ID of the relay apparatus included in the response data coincides with an ID of the relay apparatus received from the relay apparatus, the link for the access to the web server implemented on the device monitored by the relay apparatus is generated.

4. The management system according to claim 1 ,

wherein the information processing terminal is configured to display a device list based on the information for displaying the device information, and

wherein the generated link for accessing the web server implemented on the device is provided in the device list.

5. The management system according to claim 1 , wherein a screen displayed on the information processing terminal is updated according to movement of the information processing terminal or on a regular basis.

6. A control method for a management system including a device management server, an information processing terminal and a relay apparatus, wherein the device management server is configured to manage a plurality of devices using device information of the plurality of devices, wherein the relay apparatus is configured to monitor the plurality of devices that exist in a customer network and have a function for accepting cross domain communication, the control method comprising:

at the device management server:

receiving an acquisition request for the device information is received from the information processing terminal; and

sending, in response to the received acquisition request and to the information processing terminal, response data including information for displaying the device information and script information, wherein the script information includes a command to cause the information processing terminal to check perform cross domain communication for checking whether access to a web server implemented on a device is permitted, and

at the information processing terminal:

performing the cross domain communication to a web server of the relay apparatus by execution of the command included in the script information in the response data, wherein domain information corresponding to the device management server as a source of the response data is set in data which is transmitted in the cross domain communication;

receiving, from the web server of the relay apparatus, data including a determination, by the relay apparatus, using the domain information; and

generating, when the determination included in the received data indicates a permission, a link for access to a web server implemented on a device monitored by the relay apparatus from among a plurality of devices corresponding to device information displayed based on the information included in the response data,

wherein, when the determination included in the received data does not indicate the permission, the link for the access to the web server implemented on the device monitored by the relay apparatus is not generated.
