Classification: CPC H | IPC H

Claim 0:
1. A communication system comprising:
a management server configured to
transmit a login screen to an information terminal, the login screen being displayed in a web browser of the information terminal,
receive, from the information terminal connectable to a first network, login information for a user, the login information for the user being input into the web browser of the information terminal,
determine, based on the login information, whether to authenticate the user,
when the user is authenticated, transmit an instruction to display, in the web browser of the information terminal, a service list including a plurality of web services that are selectable by the user,
receive a connection request for connecting to a web service of the plurality of web services contained in the service list that are provided by a web server connectable to a second network different from the first network, and
transmit the connection request to a communication apparatus connectable to the second network;

the communication apparatus configured to
receive the connection request from the management server, and
in response to receiving the connection request from the management server, transmit a first WebSocket connection request to a relay server;

the information terminal connectable to the first network, the information terminal configured to
display the service list in response to the user being authenticated, and
transmit a second WebSocket connection request to the relay server; and

the relay server configured to
receive the first WebSocket connection request from the communication apparatus,
in response to receiving the first WebSocket connection request, establish a first encrypted communication session between the relay server and the communication apparatus,
receive the second WebSocket connection request from the information terminal, and
in response to receiving the second WebSocket connection request, establish a second encrypted communication session between the relay server and the information terminal,

wherein the first and second encrypted communication sessions enable communication of data between the information terminal and the communication apparatus through the relay server.
