摘要:
A communication terminal, a communication system and an output method. The communication terminal and the output method include storing, in a memory, a plurality of communication applications including a first communication application and a second communication application, outputting first status information indicating a first status of the first communication application according to a call control information transmitted by the first communication application, and outputting second status information indicating a second status of the second communication application according to a resource that is used by the first communication application in the first status. The communication system includes a publish-subscribe server and the communication terminal, and the communication terminal further includes sending a pub request to publish the call control information and a sub request to subscribe to the call control information to the publish-subscribe server.
摘要:
An authentication system, a communication system, and a method of performing authentication and authorization. The authentication system and the method include establishing a first connection with a communication terminal after performing authentication with client certificate sent from the communication terminal, outputting authorization data corresponding to the client certificate, the authorization data indicating authorization for the communication terminal to access a resource, and controlling the communication terminal to transmit the authorization data to a resource provision system through a second connection different from the first connection. The communication system includes the authentication system, and a resource provision system that checks the authorization data and provides the communication terminal with the resource.
摘要:
A management system includes a reception unit configured to receive identification information for identifying an account, allocated by an authentication apparatus, corresponding to a terminal, the terminal being authenticated by the authentication apparatus, and a management unit configured to determine whether a function provided by the management system can be used by the terminal based on the identification information received by the reception unit.
摘要:
A management system for managing a session for transmitting content data between a first terminal and a second terminal via a first relay apparatus and a second relay apparatus is provided. The management system includes a determination unit configured to determine a transmission quality of the content data transmitted in the session based on a transmission quality of the content data available for the first terminal and a transmission quality available for the second terminal, a first selection unit configured to select a first relay apparatus to which the first terminal is to be connected based on the determined transmission quality, and a second selection unit configured to select a second relay apparatus to which the second terminal is to be connected.
摘要:
An authentication system, a communication system, and an authentication method. The authentication system and the authentication method include receiving additional information where first identification information of a communication terminal is added to second identification information of a target to be authenticated, and authenticating the target to be authenticated using the second identification information of the target to be authenticated. When the target to be authenticated is authenticated by the authenticating, an account associated with the additional information is authorized to receive information that is sent from the communication terminal to another communication terminal. The communication system includes the authentication system and an authorization system including circuitry to authorize the account associated with the authorization data to receive information that is sent from the communication terminal to another communication terminal when the target to be authenticated is authenticated by the first circuitry.
摘要:
A disclosed control system configured to control transmission of content data between communication terminals includes one or more processors, and a memory storing instructions that, when executed by the one or more processors, cause the control system to receive a transmission request including attribute information indicating an attribute of the content data for transmitting the content data from a first communication terminal, and perform control for transmitting the content data to a second communication terminal specified based on the destination information in response to the attribute information being in a predetermined format, the predetermined format including destination information indicating a destination of the content data and to perform control for transmitting the content data to a third communication terminal that has requested reception of the content data having the attribute indicated by the attribute information in response to the attribute information not being in the predetermined format.
摘要:
A communication terminal and a method of transmitting data. The communication terminal and the method includes transmitting, at a prescribed timing, first information from the communication terminal to a management system that manages communication between the communication terminal and a counterpart communication terminal, and transmitting from the communication terminal to the management system second information to be sent from the management system to the counterpart communication terminal connected to the management system through a network, when the management system does not receive the first information transmitted from the communication terminal for a prescribed length of time. The second information includes status information of each of a plurality of communication applications that operate in the communication terminal.
摘要:
A management system, a method of controlling communication, and a communication system. The management system and method includes receiving a request to distribute information related to a prescribed attribute from a first communication terminal that is authenticated by a first client, receiving a request to receive a message related to the prescribed attribute from a second communication terminal that is authenticated by a second client, and controlling distribution of the information related to the prescribed attribute to the second communication terminal based on whether a first service that is used by the first client and a second service that is used by the second client are each associated with the prescribed attribute. The communication system includes a first communication terminal executing a first application, a second communication terminal executing a second application, and a management system to communicate with the first communication terminal and the second communication terminal.
摘要:
A control apparatus includes at least one processor configured to receive a request from a first communications terminal from among a plurality of communications terminals to select one or more relay apparatuses that relay content data transmitted and received between the first communications terminal and a second communications terminal from among the communications terminals; select one or more relay apparatuses included in one or more networks usable by the first communications terminal and the second communications terminal in response to the received request; and transmit identification information of the selected one or more relay apparatuses to the first communications terminal.
