Abstract

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.

Claims

1. A communication terminal, comprising:

processing circuitry configured to output first status information indicating a first status related to presence of a first client communication application among a plurality of client communication applications according to call control information transmitted by the first communication application, and output second status information indicating a second status related to presence of a second client communication application among the plurality of client communication applications, the second status being determined according to whether the resource is being used by the first client communication application in the first status; and

a transmitter configured to send, for each of the plurality of client communication applications, a pub request to publish the call control information and a sub request to subscribe to the call control information to a publish-subscribe server,

wherein the processing circuitry is further configured to execute an integrated client application that causes the processing circuitry to

manage a presence that indicates a status of each of the client communication applications, based on the information sent from each of the client communication applications;

request the publish-subscribe server to publish the presence of each client of the communication terminal; and

transmit a call control message sent by the client communication applications to the corresponding client communication applications of another communication terminal.

2. The communication terminal according to claim 1, wherein the processing circuitry is further configured to manage a number of available resources, and output the second status information according to the managed number of the available resources.

3. The communication terminal according to claim 2, wherein the processing circuitry is further configured to update the managed number of the available resources according to deletion or addition of the resource, or start or termination of a use of the resource.

4. The communication terminal according to claim 1, wherein

the transmitter is further configured to send, to the publish-subscribe server, a pub request to publish the first status information or the second status information, and a sub request to subscribe to the first status information or the second status information.

5. The communication terminal according to claim 4, wherein

the transmitter is further configured to use a shared account to send the pub request and the sub request to the publish-subscribe server.

6. The communication terminal of claim 1, wherein the processing circuitry is further configured to determine whether the first application is using the resource, which is one of a camera, a microphone, and a pen tablet, and determine the second status based on the determination.

7. A communication system, comprising:

a publish-subscribe server; and

a communication terminal including

processing circuitry configured to output first status information indicating a first status related to presence of a first client communication application among a plurality of client communication applications according to call control information transmitted by the first communication application, and output second status information indicating a second status related to presence of a second client communication application among the plurality of client communication applications, the second status being determined according to whether the resource is being used by the first client communication application in the first status, and

a transmitter configured to send, for each of the plurality of client communication applications, 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

wherein the processing circuitry is further configured to execute an integrated client application that causes the processing circuitry to

manage a presence that indicates a status of each of the client communication applications, based on the information sent from each of the client communication applications;

request the publish-subscribe server to publish the presence of each client of the communication terminal; and

transmit a call control message sent by the client communication applications to the corresponding client communication applications of another communication terminal.

8. The communication system according to claim 7, further comprising

a relay control device configured to manage a relay of contents of data between the communication terminal and another communication terminal,

wherein the relay control device is further configured to send, to the publish-subscribe server, a sub request to subscribe to the call control information.

9. The communication system according to claim 7, wherein

the transmitter is further configured to send, to the publish-subscribe server, a sub request to publish the first status information or the second status information and a pub request to subscribe to the first status information or the second status information.

10. The communication system according to claim 7, further comprising

another communication terminal that is a counterpart communication terminal of the plurality of communication applications.

11. An output method, comprising:

outputting first status information indicating a first status related to presence of a first client communication application among a plurality of client communication applications according to a call control information transmitted by the first communication application;

outputting second status information indicating a second status related to presence of a second client communication application among the plurality of client communication applications, the second status being determined according to whether the resource is being used by the first client communication application in the first status;

sending for each of the plurality of client communication applications, a pub request to publish the call control information and a sub request to subscribe to the call control information to a publish-subscribe server;

managing a presence that indicates a status of each of the client communication applications, based on the information sent from each of the client communication applications;

requesting the publish-subscribe server to publish the presence of each client of the communication terminal; and

transmitting a call control message sent by the client communication applications to the corresponding client communication applications of another communication terminal.
