摘要:
One or more LAN switches capable of accessing the contents of a MAC address table, which the LAN switch contains, from the outside; and a presence server storing in a storage device a first correspondence table between a MAC address of a network interface, which equipment contains, and its user, and a second correspondence table between a port of the above-described LAN switch, and a physical range wired therefrom, are used to thereby obtain a correspondence table between the equipment, its user, and its physical location (range), whereby making applicable also to a wired LAN at the time of determining the location of the equipment or the location of a user using the equipment in a building, and making realizable at low cost, and allowing the location to be determined accurately within a predetermined segmented area, and not being affected even if an IP address is changed.

A wireless IP telephone system including a dynamic address lease server for leasing an IP address to each of terminals and a controller. The controller has information about the IP address, a SIP URI of the terminal, a type thereof, and a function thereof. The information of the controller is dynamically set by a system administrator who manually sets the information or by the dynamic address lease server and the controller which are cooperated. The controller decides an effective period of the address to be leased to each terminal, informs the dynamic address lease server of the fact, and requires the address lease server to release the address which became unnecessary.

In a thin client system which provides a high-quality picture reproduction method and which makes it possible to use a thin client terminal as a TeleVision (TV) phone terminal and a TV conference terminal, a video reproducing module is disposed in a thin client server device and a graphics module is disposed in a thin client terminal. The thin client server device sets a transmission color to a video display area of screen data and sends the screen data via a remote control communication path and simultaneously sends video data via a second route. The thin client terminal receives the screen data and the video data and displays the screen and video data as an overlay image in one same screen using the screen overlay scheme.

A method and apparatus for file operation comprise a file operation method which enters, prior to the file operation, processing methods for exceptional events which are expected to occur during the file operation, a file operation method which, at the occurrence of an exceptional event during a file operation, holds the file operation, saves information pertinent to the held file into a memory, and inquires the user of the processing method of the held file for the exceptional event, and a file operation method which displays a list of hierarchically organized files at multiple levels so that multiple files can be designated as objects of operations.
摘要:
In IP telephony systems, it has become impossible to detect the location of installation of a telephone terminal from the telephone number, since an IP telephone terminal can be installed in an arbitrary location. Also, even if one observes the calling party number presentation at the time of an incoming call, it has become impossible to grasp from where the calling party is placing the outgoing call. It is possible that, within an IP telephony system, a terminal location detection means is configured and the installation location of a telephone terminal is detected simultaneously with the registration of the telephone terminal. In addition, the problem can be solved by configuring, in an IP telephony server, a device of reporting location information about the correspondent to the telephone terminal and by configuring, in the telephone terminal, a device of displaying the received positional information.

A call management system is configured of a client terminal 200 and a management server 100. The client terminal 200 executes a presence detection process by communicating with a call device 50 and acquiring presence information including a user ID, and a presence transmission process of transmitting, to a management server 100, presence information including the presence information of the detected user and the ID of the client terminal 200 itself. The management server 100 executes a presence acquiring process of receiving the presence information and storing the information in a user management table; a coupling destination reading process of, upon receipt of a call originated by a communication terminal 30, reading the presence information of a user corresponding to a telephone number of a call destination and information on an assigned client server 300, from the user management table as coupling destination information; and a coupling request process of transmitting, to the assigned client server 300, a call coupling request which includes coupling information of the communication terminal, and which requests establishment of a call between the communication terminal 30 and the call device 50.

An extension telephone using an ordinary telephone circuit cannot be coordinated with a data terminal connected by an IP network. An extension telephone using an ordinary telephone circuit has none of the convenient functions of an IP telephone, such as implementing outgoing/incoming call data management and telephone book management on a PC. A telephone terminal using an ordinary telephone circuit and a data terminal in an IP network can however be coordinated by reflecting telephone calls and call signal details in an IP network by means of a telephone adapter which can send and receive IP network data and call signals using IP network data as a trigger. A user of an ordinary telephone system can easily coordinate a telephone with a data terminal, and even if there is a “modernization time lag” between the data system and telephone system, or the IP telephone system is introduced gradually, an environment is created whereby all users can make maximum use of coordination between the data system and telephone system.
摘要:
To provide a thin client (TC) system at least capable of using a thin client terminal as a telephone terminal in a thin client system. In a personal TC (PTC) system consisting of a PTC server with a server side telephone control section consisting of a call control section, and a PTC terminal with a terminal side telephone control section consisting of a device control section and a voice packet communication section, and a handset connected to the PTC terminal, this is achieved by notifying an IP address of the PTC terminal as an communication target IP address to be notified upon call connection, and notifying the PTC terminal an IP address of a telephone terminal.
