Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service providing system in an IVD-LAN system. In recent years, it has been desired to realize a service-integrated network, and LANs (Local Ar
ea network) and PBX (Private Branch eXchange: Private Branch eXchange), which has been introduced at each business center mainly for voice (telephone), has been actively integrated, and ISDN
As a network that realizes integrated services such as (Integrated Services Digital Network), IVD-LAN (Integrated Voice and
Data LAN: A voice / data integrated LAN) system has been developed.

In this type of IVD-LAN system, various services (for example, conference telephone service) defined as services for communication between voice terminals are used with the data terminal by utilizing the merit of voice / data integration. There is a demand to improve the convenience by providing it through cooperation.

[0003]

2. Description of the Related Art In a conventional IVD-LAN system, a voice channel and a data P channel (P-ch) for high-speed packet communication are separated from each other, and a data P channel is used in communication between voice terminals. It is not possible to communicate using the channel, and the service provided for data terminal communication and the service provided for voice terminal communication are independent of each other.

[0004]

Therefore, for example, in the conference telephone service provided for communication between voice terminals, the medium for recognizing the progress of the conference of the conference participants is only the voice from the voice terminals. Therefore, the recognition of the conference participant and the speaker who is currently speaking depends on the memory of the voice of the speaker, and when many unfamiliar persons are present, each participant speaks. Before that, it was necessary to give his / her own name every time, and there was a problem that the proceedings could not proceed smoothly.

Further, even if there is a material that needs to be stored during the communication between voice terminals, no service is provided for transferring the communication between voice terminals, which is completely different from the communication between voice terminals. There is a problem in that it is necessary to independently transfer the material using the communication between the data terminals, which is inconvenient.

The present invention has been made in view of the above circumstances, and in the IVD-LAN system, various services (services for voice terminal-to-voice terminal communication) defined by utilizing the merit of voice / data integration ( For example,
The purpose is to improve the convenience by making it possible to provide the conference telephone service) in cooperation with the data terminal.

[0007]

The principle of the present invention shown in FIGS. 1 and 2 will be described with reference to FIGS. 1 shows the main part, and FIG. 2 shows the entire system.

In this IVD-LAN system, as shown in FIG. 2, a voice terminal 1 and a data terminal (personal computer, workstation, etc.) 2 are accommodated in a switchboard (PBX) 4 via a terminal adapter (TA) 3. A voice communication network that realizes communication between voice terminals, which is communication between a voice terminal and another voice terminal, and a data communication network that realizes communication between data terminals, which is communication between a data terminal and another data terminal. It is an integrated communication network.

The terminal adapter 3 is a device for performing protocol conversion of voice communication information from the voice terminal 1 and / or data communication information from the data terminal 2 into an IVD interface and sending it to the exchange 4, or vice versa.

The voice communication information from the voice terminal 1 is sent by the terminal adapter 3 together with the data communication information from the data terminal 2 to the line processor (LPR) 5 of the exchange 4.
To the call processor (CPR) 6, and the call processor 6 performs processing for providing various services (for example, conference telephone service) for communication between voice terminals and control of each unit.

The line processor 5 is a LAN high-speed bus (H-B) controlled by a high-speed bus controller (not shown).
US) 7 to another similar line processor.

Next, referring to FIG. The call processor 6, during the service provision for communication between voice terminals,
L according to the program for providing the service
As one of the PR control orders (commands for requesting processing to the line processor 5 to realize various services), an order for realizing the present invention (referred to as a data terminal control order) is sent to the line processor 5.

The line processor 5 executes a CPR order analysis process. That is, it is determined whether the order from the call processor 6 is a data terminal control order (ST
1) If the order is other than the data terminal control order, the process corresponding to the applicable order is performed.

In the case of the data terminal control order, the information corresponding to the content of the data terminal control order and the data terminal control information managed in the exchange 4 based on the content of the data terminal control order, It is reprinted on the downlink P channel (dedicated channel for high-speed packet communication in the data system) between the exchange and the data terminal realized by the IVD interface, and from the exchange 4 to the terminal adapter 3 to which the voice terminal 1 in communication is connected. Connected data terminal 2
Transfer to.

The term "downstream" means the direction from the exchange to the data terminal, and the opposite direction from the data terminal to the exchange is called "uplink". The information transferred using the downlink P channel is output to the display or printer of the data terminal 2 or stored in the storage device according to the data terminal control information transferred using the downlink P channel.

[0016]

According to the present invention, the information managed in the exchange (for example, the P channel, which is a dedicated channel for the high speed packet communication of the data system, during the execution of the services for the communication between various voice terminals (for example, The information to be displayed on the display of the data terminal, the information to be stored in the storage device of the data terminal) and the data terminal control information for processing the information in the data terminal are reproduced. In the service for inter-communication, it is possible to provide a service that also uses a data terminal, and it is possible to provide a service with improved serviceability.

For example, in the conference telephone service provided for communication between voice terminals, the names of the conference participants are registered, this information is displayed on the display of the data terminal using the P channel, and the speech during the speech is made. By detecting the person by some means and sending it to the data terminal using the P channel as well, by highlighting or reversing the name of the participant who is speaking among the conference participants displayed on the display. By making a distinction, it becomes unnecessary for each participant to give his / her name each time before speaking, which is conventionally done, and the proceedings of proceedings can be facilitated.

Further, for example, if there is a material that needs to be stored during communication between voice terminals, it can be transferred to the corresponding data terminal using the P channel and stored in the storage device. However, the troublesomeness of another independent method (for example, separately performing a procedure for communication between data terminals to transfer data) is eliminated, and convenience can be improved.
