Abstract: The present invention is to provide a media burst control system in a multimedia service using one or more media servers in which the floor is synchronized between the media. A floor management server 30 for managing the floor allocation policy for multimedia is provided independent of a group of media servers 20 for providing media services. The floor allocation policy for multimedia to be allocated to the group of media servers is stored in a floor allocation policy portion 33 and control is made so as to synchronize the floor of the respective media by a floor allocation judgment portion 32. The floor allocation policy portion 33 is designed to integrate for setting the policies set for respective media servers of the group of media servers 20 or to enter the policy for multimedia from any terminal of the group of terminals 10 or a server such as a presence server 40 or the like.

Abstract: A communication control that holds setting information applied when a communication among a first user terminal, a second user terminal, and a plurality of server apparatuses each supplying service data corresponding to a predetermined service to the first user terminal is established while associating the setting information with the service is provided. The communication control apparatus generates invitation information, based on the setting information, for establishing a communication between the second user terminal and each of the plurality of server apparatuses when receiving an invitation instruction for indicating the control unit to supply the service data on the service to the second user terminal from the first user terminal and supplies the invitation information to the plurality of server apparatuses and the second user, respectively.

Abstract: A multimodal service establishing method is provided which is capable of achieving flexible combinations of a plurality of service contents. At least one integrated server is installed between a plurality of terminal devices and service servers of a plurality of types. A session establishment processing unit and service linking processing unit are mounted in the integrated server. The session establishment processing unit establishes multimodal service session between terminals and service servers. After the establishment of multimodal service session, the service linking processing unit provides new service obtained by linking and integrating service to be provided by service servers, that is, multimodal service to terminal devices.
