In accordance with the communication management apparatus, the upper limit of number of symbols (users) capable of joining in the communication area is defined for each communication area. According to the communication management apparatus, it is possible to provide a user management system abounding in flexibility.
Abstract:
In a communication system in which a server, who offers information, and clients, who receive information offering service, are connected with each other via a network, the server has a communication mode selection unit for switching over a communication mode for each client between a one-way communication mode in which information is offered to clients on a one-way basis and a two-way communication mode in which messages are transmitted to clients and messages transmitted from the clients are received.
Abstract:
A designing and managing system for a communications network having a physical network and a logical network includes a designing system adaptable to a traffic fluctuation through a simple procedure, and a managing system for quickly selecting a suitable communications path in response to a path connection request and a path capacity change request. The designing system has units for respectively determining the topologies of the physical network and the logical network independently of traffic conditions, and units for setting the path capacities of the physical network and the logical network, respectively, based upon a long-term traffic demand and an actual request. The managing system includes a unit for registering the limited number of detour path candidates, a unit for determining the existence of a detour path in response to a virtual path connection request, and a unit, provided in a start point node of a communications path, for determining the acceptability of a change in the capacity of a path based on a value of a size of each link forming part of the communications path.
Abstract:
A process information generating section produces a communication process information necessary for a communication process. A status predicting section receives a statistically-processed status information from another node when the status of this another node has changed, and produces a prediction information predictive of the statuses of all other nodes, excluding this local node, based on the status information. A routing control section performs control to select a communications path which minimizes a network load, based on the communication process information generated by the process information generating section and the prediction information obtained by a status predicting section.
Abstract:
A communication control apparatus that manages a media condition and a communication state of communication terminals in an integrated manner and optimizes a communication terminal environment according to events of various types is provided. A communication control module includes a terminal control portion for retaining a media information that can be handled by each of communication terminal devices belonging to a group of terminals available to one user and sending and receiving a call control information between the communication terminal devices, a virtual terminal portion that, by controlling a call with respect to the communication terminal device of another user based on the call control information, functions for the another user as a single virtual terminal, and a terminal environment optimizing portion that, at a time when an occurrence of an event is detected, refers to a media information of the event and the media information in the terminal control portion so as to determine a communication media condition corresponding to the event, and selects a communication terminal device matching this condition.
Abstract:
A ubiquitous communication system that can be used without changing a user ID etc. of a terminal of others or causing problems such as information leakage is provided. A terminal management apparatus for managing terminals on a ubiquitous communication system is provided with a terminal management portion for retaining information about terminals belonging to each of the users, a parent registration list in which a terminal that another user is allowed to use and the another user who is allowed to use the terminal are pre-registered, a child registration list in which a terminal borrowable from another user and the another user to which the terminal belongs are pre-registered, and an association setting portion for, when a first user makes an association setting request on a terminal belonging to a second user, referring to the lists and, if it is judged that the first user may be allowed to use the terminal belonging to the second user, registering the terminal belonging to the second user in the terminal management portion of the first user.
Abstract:
To enable reporting user status more precisely and over a wide range, the present invention includes an information terminal PC1 having a generating device, a mobile terminal M having a transmitting device, and an information terminal PC2 having a receiving device. The information terminal PC1 and the mobile terminal M can communicate directly wirelessly or through a wire. The mobile terminal M and the information terminal PC2 can communicate in real time via status notification devices. The information terminal PC1 reports the user status it detected to a mobile terminal M that is in a communicable area. The mobile terminal M sends the user status to the information terminal PC2 via the status notification device if the user status it received is the status of the user that has been stored therein in advance. If the user carries a mobile terminal M while he is on the trip, the status can be reported from the information terminal PC1 to the information terminal PC2 regardless of whether the information terminal PC1 belongs to a network or whether the information terminal PC1 has a certain status notification device.
Abstract:
There is provided a communication apparatus, adapted to be used as a user terminal, connected to a message communication system in which a plurality of user terminals are interconnected, the plurality of user terminals sharing virtual worlds and avatars (symbols) of users each operating an associated one of the user terminals, and messages are exchanged among the plurality of user terminals while creating an atmosphere such that as if one's own self enters the virtual world and has conversations. In the communication apparatus, the users (symbols) are classified into a plurality of categories, and action contents of the symbols are controlled in accordance with the categories. According to the communication apparatus, a symbol with a great deal of individuality is produced, so that a virtual world full of variety may be implemented.
Abstract:
There is provided a communication apparatus for exchanging messages while a virtual space and avatars (symbols) of users are displayed on a display screen. The communication apparatus has a viewpoint element inputting unit for inputting a viewpoint element (a viewpoint position and a viewpoint direction). An image of the virtual space is produced on the basis of the viewpoint element inputted from the viewpoint element inputting unit. According to the communication apparatus, it is possible to increase a degree of freedom in plotting the virtual space.
Abstract:
The method is executed by a call control server that establishes a media session for sending and receiving media data between a calling terminal and a called terminal. The method includes exchanging messages with calling terminal and called terminal for establishing the media session, generating a session information necessary for establishing the media session based on the messages exchanged with the calling terminal and/or the called terminal, monitoring a media information included in the messages, the media information containing a definition specifying a way of exchanging the media data, determining, based on the monitoring result, whether the media session has been established, and transferring the session information to at least one other call control server different from the call control server if the media session has been established.
