There is provided a communication system and a communication method of making available both a shared telephone number shared by multiple communication terminals and an individual telephone number dedicated to a user's own terminal in a single communication terminal. A shared managing unit 11 of a communication system 1 manages terminal identifiers 1 and 3 identifying each of a plurality of communication terminals 30a and 30b to which a shared telephone number is assigned in correlation with the shared telephone number. An individual managing unit 12 manages a terminal identifier 2 identifying a communication terminal 30b to which an individual telephone number is assigned is correlation with the individual telephone number. A user information managing unit 13 manages user information including base station information of communication terminals identified by the identifier every terminal identifiers 1, 2, and 3. A call control device 20 carries out call control of communication terminals 30b, to which the shared telephone number and an individual telephone number are assigned, using this information.

There are provided a server apparatus capable of transmitting any message in a flexible manner at various timings of communication service states, and a message transmission method thereof. When a communication trigger detector 103 of an IMS 100 detects a trigger point, a determination portion 104 determines a massage to be transmitted based upon at least one of a type of the communication service state, a transmission destination of the message, presence information, and an instruction input. A message transmitter 105 give an instruction to an information storage device 300 to transmit the message to be transmitted that has been determined, and the information storage device 300 transmits the message to the transmission destination.

There are provided a video editing system, a video editing server and a communication terminal which enable simultaneous editing operations for editing a video content to be performed by plural persons, without generating a file in which a content of the editing has been reflected in the video content. One of a plurality of editing terminals in a synchronized state generates an edit command for editing a video content with an edit command generating section, based on an editing operation by a user from a terminal operating section, and transmits the generated edit command to a video editing server via an information transmitting/receiving section. If the edit command is received via an information transmitting/receiving section, the video editing server transmits the received edit command to another editing terminal in the synchronized state, via an edit command synchronizing section. If the edit command is received via the information transmitting/receiving section, another editing terminal in the synchronized state displays a content of the edit command on a screen displaying section via an edit command displaying section.
摘要:
It is an object of the present invention to ensure readily communication between subgroups with reduced trouble to the user in the group communication in terms of subgroup formation and so on. A group communication server according to an embodiment of the present invention provides terminals with an intercommunication function between a plurality of terminals belonging to the same group, specifically a group communication function. The group communication server comprises a group information database for storing subgroup information that specifies terminals belonging to subgroups comprising a plurality of terminals of the terminals belonging to the group, and timing information that indicates a timing for establishing connection for intercommunication between the terminals belonging to these subgroups, and a group management unit and connection control unit which constitute control means for executing a control to establish connection between the terminals belonging to the subgroups specified by the subgroup information at a timing specified by the timing information stored in the group information database.
摘要:
An object of the present invention is to avoid packet loss and implement a seamless handover by minimizing the handover latency when a handover is implemented by a multihomed moving network (MN) or a mobile host (MH). The present invention is a mobile communication system that is constituted comprising an MN, a plurality of AI each constituting an interface for the connection to a core network at the MN, and a control device (MMF), wherein the MMF dynamically changes the AI adopted as the connection interface when a predetermined condition is satisfied on the basis of the connection status to the core network at each AI or the prediction information for a subsequent handover. In so doing, the control device continues the transmission and receipt of data with respect to an appropriate AI capable of maintaining a predetermined communication quality, and maintains the connection to the core network of another AI while causing this AI to enter a closed state in which the transmission and receipt of data is disabled.

There are a step in which, when the video data distribution request is received from the mobile station, the base station determines whether the requested video data can be distributed or not, on the basis of the wireless transmission capacity required for distributing the requested video data and the wireless transmission capacity that is available at that point of time, a step in which the base station notifies the mobile station of a result of possibility determination about distribution, a step in which, when it is determined that distribution cannot be performed, the base station sends an inquiry about a base station capable of performing distribution, to the transmitted-data capacity management device, a step in which the transmitted-data capacity management device selects base stations capable of performing the distribution, on the basis of the wireless transmission capacity required for distributing the video data and the wireless transmission capacity being used for distribution performed by a plurality of base stations, and replies with the selected base stations, and a step in which the base station notifies the mobile station of the base stations capable of performing the distribution.
