Abstract

The object of the present invention is to realize a method and a server which enable insertion of advertisement even in voice communication including multimedia communication. The server is configured as a server for managing PoC communication among multiple terminals, comprising: a right-to-speak management section for managing the right to speak of the multiple terminals; a data distribution section for transmitting and receiving data to and from the multiple terminals; and an advertisement control section for storing advertisement data and transmitting the stored advertisement data to the multiple terminals via the data distribution section.

Claims

1. A server for managing PoC communication among multiple terminals, comprising:

a right-to-speak management section for managing the right to speak of the multiple terminals;

a data distribution section for transmitting and receiving data to and from the multiple terminals; and

an advertisement control section for storing advertisement data and transmitting the stored advertisement data to the multiple terminals via the data distribution section.

2. The server according to claim 1, wherein

when receiving speech data by any of the multiple terminals ends, the data distribution section transmits an end-of-speech notification to that effect to the advertisement control section, and when accepting advertisement data from the advertisement control section, the data distribution section transmits the advertisement data to each of the multiple terminals;

and

when accepting the end-of-speech notification, the advertisement control section causes the right-to-speak management section to suspend a response to the request for the right to speak by each terminal and transmits the stored advertisement data to the data distribution section.

3. The server according to claim 1, wherein

when a PoC communication session is started, the advertisement control section causes the right-to-speak management section to suspend a response to the request for the right to speak by the multiple terminals and transmits the stored advertisement data to the data distribution section;

and

when accepting the advertisement data from the advertisement control section, the data distribution section transmits the advertisement data to each of the multiple terminals.

4. The server according to claim 1, wherein

when issuing the right to speak to any of the multiple terminals, the right-to-speak management section transmits a right-to-speak issue notification to that effect to the advertisement control section;

when accepting the right-to-speak issue notification, the advertisement control section transmits the stored advertisement data to the data distribution section; and

when accepting advertisement data from the advertisement control section, the data distribution section transmits the advertisement data and speech data from the terminal to which the right to speak has been issued to each of the terminals other than the terminal to which the right to speak has been issued.

5. The server according to claim 1, wherein

when issuing the right to speak to any of the multiple terminals, the right-to-speak management section transmits a right-to-speak issue notification to that effect to the advertisement control section;

when receiving speech data by any of the multiple terminals ends, the data distribution section transmits an end-of-speech notification to that effect to the advertisement control section, and when accepting advertisement data from the advertisement control section, the data distribution section transmits the advertisement data to each of the multiple terminals; and

if the right-to-speak issue notification is not accepted even when a predetermined time has lapsed after acceptance of the end-of-speech notification, the advertisement control section requests the right to speak from the right-to-speech management section, and transmits the stored advertisement data to the data distribution section if the right to speak has been acquired.

6. The server as in any of claims 1 to 5, wherein advertisement data includes picture data, and the data distribution section specifies a medium which is not used by the PoC communication and transmits the advertisement data to each terminal.

7. An advertisement insertion method to be performed in a server comprising:

a right-to-speak management section for managing PoC communication among multiple terminals and for managing the right to speak of the multiple terminals;

a data distribution section for transmitting and receiving data to and from the multiple terminals; and

an advertisement control section for storing advertisement data;

wherein

the advertisement control section transmits the stored advertisement data to the multiple terminals via the data distribution section.

8. The advertisement insertion method according to claim 7, wherein

when receiving speech data by any of the multiple terminals ends, the data distribution section transmits an end-of-speech notification to that effect to the advertisement control section, and when accepting advertisement data from the advertisement control section, the data distribution section transmits the advertisement data to each of the multiple terminals;

and

when accepting the end-of-speech notification, the advertisement control section causes the right-to-speak management section to suspend a response to the request for the right to speak by each terminal and transmits the stored advertisement data to the data distribution section.

9. The advertisement insertion method according to claim 7, wherein

when a PoC communication session is started, the advertisement control section causes the right-to-speak management section to suspend a response to the request for the right to speak by the multiple terminals and transmits the stored advertisement data to the data distribution section;

and

when accepting the advertisement data from the advertisement control section, the data distribution section transmits the advertisement data to each of the multiple terminals.

10. The advertisement insertion method according to claim 7, wherein

when issuing the right to speak to any of the multiple terminals, the right-to-speak management section transmits a right-to-speak issue notification to that effect to the advertisement control section;

when accepting the right-to-speak issue notification, the advertisement control section transmits the stored advertisement data to the data distribution section; and

when accepting the advertisement data from the advertisement control section, the data distribution section transmits the advertisement data and speech data from the terminal to which the right to speak has been issued to each of the terminals other than the terminal to which the right to speak has been issued.

11. The advertisement insertion method according to claim 7, wherein

when issuing the right to speak to any of the multiple terminals, the right-to-speak management section transmits a right-to-speak issue notification to that effect to the advertisement control section;

when receiving of speech data by any of the multiple terminals ends, the data distribution section transmits an end-of-speech notification to that effect to the advertisement control section, and when accepting advertisement data from the advertisement control section, the data distribution section transmits the advertisement data to each of the multiple terminals; and

if the right-to-speak issue notification is not accepted even when a predetermined time has lapsed after acceptance of the end-of-speech notification, the advertisement control section requests the right to speak from the right-to-speech management section, and transmits the stored advertisement data to the data distribution section if the right to speak has been acquired.

12. The advertisement insertion method as in any of claims 7 to 11 ,wherein advertisement data includes picture data, and the data distribution section specifies a medium which is not used by the PoC communication and transmits the advertisement data to each terminal.
