Abstract

A communication system include: a first acquisition unit configured to acquire request information of session initiation and authentication information of session participation; a session management unit configured to establish the session between the first terminal and the second terminal; a second acquisition unit configured to acquire request information of session participation and the authentication information of session participation being input by a third terminal; and a participation determination unit configured to compare the authentication information of session participation obtained by the first acquisition unit with the authentication information of session participation obtained by the second acquisition unit, and the participation determination unit allowing the third terminal to participate in the session when the authentication information of session participation obtained by the first acquisition unit is identical to the authentication information of session participation obtained by the second acquisition unit.

Claims16

Dependent claims

A communication system comprising:

a network interface configured to:
receive request information of session initiation from a first terminal and first authentication information of session participation, the request information of session initiation requesting for initiation of a session between the first terminal and a second terminal and indicating whether or not there is session participation restriction for at least one terminal other than the first terminal and the second terminal, and the first authentication information of session participation being provided for authenticating participation in the session when the request information of session initiation indicates that there is the session participation restriction;
and
receive request information of session participation and second authentication information of session participation from a third terminal, the request information of session participation being a request for participation in the session;
and
circuitry configured to:
establish the session between the first terminal and the second terminal according to the request information of session initiation;
output, for display on a display of the second terminal, an initiation request acceptance screen indicating that the session has the session participation restriction when the request information of session initiation indicates that there is the session participation restriction;
compare the first authentication information of session participation with the second authentication information of session participation in response to the request information of session participation when the request information of session initiation indicates that there is the session participation restriction;
and
cause the third terminal to participate in the session when the first authentication information of session participation is identical to the second authentication information of session participation.

8 more elements

A non-transitory computer readable medium including a computer program product, the computer program product comprising instructions which, when executed by a computer, causes the computer to perform operations comprising:

receiving request information of session initiation from a first terminal and first authentication information of session participation, the request information of session initiation requesting for initiation of a session between the first terminal and a second terminal and indicating whether or not there is session participation restriction for at least one terminal other than the first terminal and the second terminal, and the first authentication information of session participation being provided for authenticating participation in the session when the request information of session initiation indicates that there is the session participation restriction;
establishing the session between the first terminal and the second terminal according to the request information of session initiation;
outputting, for display on a display of the second terminal, an initiation request acceptance screen indicating that the session has the session participation restriction when the request information of session initiation indicates that there is the session participation restriction;
receiving request information of session participation and second authentication information of session participation from a third terminal, the request information of session participation being a request for participation in the session;
comparing the first authentication information of session participation with the second authentication information of session participation in response to the request information of session participation when the request information of session initiation indicates that there is the session participation restriction;
and
causing the third terminal to participate in the session when the first authentication information of session participation is identical to the second authentication information of session.
