Abstract

A disclosed communication apparatus includes a receiving unit that receives metadata of update data used for an update; a determination unit that determines, based on a description of the metadata, whether or not there is update data that is subject to advance download in which download of the update data is executed before a point of time at which the update is able to start; a control unit that determines whether or not it is timing to perform the advance download; and an update processing unit that downloads the update data in a case in which the determination unit determines that there is the update data that is subject to the advance download and the control unit determines that it is the timing to perform the advance download.

Claims

1. A communication method comprising:

receiving metadata of update data used for an update to a communication terminal connectable to an update server;

determining, based on a description of the metadata, whether or not there is update data that is subject to advance download in which download of the update data is performed before a point of time at which the update is able to start;

determining whether or not it is time to perform the advance download;

downloading the update data in a case in which it is determined that there is the update data that is subject to the advance download in said determining whether or not there is update data and it is determined that it is the time to perform the advance download in said determining whether or not it is the time to perform the advance download; and

determining that it is the time to perform the advance download and start or restart the advance download, in a case in which a video conference application is activated and a video conference is not started,

wherein in a case in which the video conference is started, said determining determines that it is not the time to perform the advance download and stops the advance download, and

wherein in a case in which said determining determines that it is not the time to perform the advance download and stops the advance download, the advance download is stopped after downloading all data being downloaded in a case in which a downloaded data amount is equal to or greater than half of the data being download.

2. The communication method according to claim 1, wherein the data is divided data, and the data amount is a data amount of the divided data being downloaded.

3. A communication terminal comprising:

circuitry having memory, the circuitry configured to

receive metadata of update data used for an update from an update server via a network,

determine, based on a description of the metadata, whether or not there is update data that is subject to advance download in which download of the update data is performed before a point of time at which the update is able to start,

determine whether or not it is time to perform the advance download,

download the update data in a case in which the determination determines that there is the update data that is subject to the advance download and the determination determines that it is the time to perform the advance download, and

determine that it is the time to perform the advance download and start or restart the advance download, in a case in which a video conference application is activated and a video conference is not started,

wherein in a case in which the video conference is started, the circuitry determines that it is not the time to perform the advance download and stops the advance download, and

wherein in a case in which the circuitry determines that it is not the time to perform the advance download and stops the advance download, the circuitry stops the advance download after downloading all data being downloaded in a case in which a downloaded data amount is equal to or greater than half of the data being download.

4. The communication terminal according to claim 3, wherein in a case in which the circuitry determines that it is not the time to perform the advance download and stops the advance download, the circuitry stops the advance download while discarding data being downloaded in a case in which a downloaded data amount is equal to or less than half of the data being download.

5. The communication terminal according to claim 3, wherein the data is divided data, and the data amount is a data amount of the divided data being downloaded.

6. The communication terminal according to claim 3, wherein the circuitry is configured to determine whether or not there is advance download data for advanced downloading after the determining determines that it is the time to perform the advance download.

7. The communication terminal according to claim 6, wherein the circuitry determines there is not advance download data for advanced downloading when all of the update data has already been downloaded.

8. The communication terminal according to claim 3, wherein the advanced download is performed and completed prior to start of the video conference.

9. A communication system including an update server and a communication terminal connectable via a network,

wherein the update server includes:

circuitry configured to

provide update data and metadata in response to a request from the communication terminal, receive the metadata of the update data used for an update,

determine, based on a description of the metadata, whether or not there is update data that is subject to advance download in which download of the update data is performed before a point of time at which the update is able to start,

determine whether or not it is time to perform the advance download,

download the update data in a case in which the determination determines that there is the update data that is subject to the advance download and the determination determines that it is the time to perform the advance download, and

determine that it is the time to perform the advance download and start or restart the advance download, in a case in which a video conference application is activated and a video conference is not started,

wherein in a case in which the video conference is started, the circuitry determines that it is not the time to perform the advance download and stops the advance download, and

wherein in a case in which the circuitry determines that it is not the time to perform the advance download and stops the advance download, the circuitry stops the advance download after downloading all data being downloaded in a case in which a downloaded data amount is equal to or greater than half of the data being download.

10. The communication system according to claim 9, wherein in a case in which the circuitry determines that it is not the time to perform the advance download and stops the advance download, the circuitry stops the advance download while discarding data being downloaded in a case in which a downloaded data amount is equal to or less than half of the data being download.

11. The communication system according to claim 9, wherein the data is divided data, and the data amount is a data amount of the divided data being downloaded.

12. The communication system according to claim 9, wherein the advanced download is performed and completed prior to start of the video conference.
