Abstract

PURPOSE:To provide a private exchange equipped with intelligent network service (IS) function which can be uniformly adapted and rich in versatility, when adding the IS even to any kind of the private exchange. CONSTITUTION:At a private branch exchange 25, a signal controller 24 and a high-function processor 26 are externally connected. The signal controller 24 discriminates whether a call originating signal requests the IS or not and in the case of YES, that signal is transferred to the high-function processor 26. The high-function processor 26 retrieves a procedure and data and returns them to the signal controller 24. Corresponding to those procedure and data, the signal controller 24 provides the IS. Since the inside of the private exchange 25 is not altered at all and the signal controller 24 and the high-function processor 26 are just externally connected, the private branch exchange 25 can ignore its kind and is rich in versatility.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a premises type intelligent network device and method. In a private branch exchange capable of connecting a plurality of terminals in a premises such as a business office and connecting between the plurality of terminals and a public network, a call requesting an intelligent network service from a terminal side is made. An apparatus and method capable of identifying such a situation and providing the intelligent network service when the situation occurs is referred to as a premises intelligent network apparatus and method.

[0002] Here, the intelligent network service will be briefly described. A technology called an intelligent network has been developed in which a computer is used for controlling and operating a telephone network so as to promptly respond to various services to end users. As described above, the intelligent network rationally tries to provide various network services that meet the user's request, and the call control is performed for the latter of the "basic service" and the "additional service" provided by the network. It is intended to improve the processing.

The intelligent network service is mainly a service in which a caller can freely select a communication acceptance method at a time unit according to a user's intention. A media conversion service, a group communication service, a simultaneous broadcasting service and a virtual private network. Intended for services. The communication reception method is intended for tracing connection for each caller, message reception, caller name display, reception refusal, voice character conversion reception, and the like.

The premises intelligent network service is a service for realizing communication between mobile terminals scattered in the premises (for example, assuming a wide area covering the whole office) in a private branch exchange, or a special service. There are various services such as a service for connecting to a communication terminal of a procedure (a terminal that presents an answering machine function or a transfer function depending on the situation when an incoming call arrives). The present invention relates to a premises type intelligent network device and method in this sense.

[0005]

2. Description of the Related Art FIG. 6 is an explanatory diagram showing an example of additional modification of hardware and software required when adding an intelligent network service to a conventional private branch exchange.

In the figure, 1 is a speech path switch, 2 is a control device, 3 is a subscriber circuit, 4 is a location registration memory, 5 is a connection interface device, 6 is a service control device, and 10 is a service control device.
Is a private branch exchange, 11 is a mobile communication terminal, 12 is a base station apparatus, 13 is a communication terminal, and 14 is a public network.

When an attempt is made to add a service that enables connection with a moving communication terminal to the conventional private branch exchange as an intelligent network service, it is necessary to communicate with the mobile terminal via a base station. Subscriber circuit 3, a location registration memory 4 for storing the location of the mobile terminal when it is checked, or a service control device 6 having a built-in location registration memory, if used, a connection interface device with it. 5 and so on, and the software 7 in the control device 2 has to be modified accordingly.

[0008]

The exchange device for the premises is
In general, since it only has the basic functions as an exchange,
Adding an intelligent network service requires additional hardware and software modifications as already described with reference to FIG. Further, even if the additional modification is performed, the technique can be applied only to the same type of private branch exchange device and cannot be applied to other types of private branch exchange devices, and lacks versatility.

The present invention solves the problems of the prior art, and has a structure that can be uniformly applied to any type of private branch exchange to add an intelligent network service and is versatile. Another object of the present invention is to provide a private intelligent network device (a private branch exchange device having an intelligent network service function) and its method.

[0010]

To achieve the above object, in the present invention, a plurality of terminals in a premises such as a business office are connected to each other and a connection between the plurality of terminals and a public network is made. We decided to connect the signal control unit and the high-performance processing unit externally in the private branch exchange. Since the contents of the private branch exchange device are not modified at all and only the signal control device and the high-performance processing device are externally connected, the type of the private branch exchange device does not matter and the versatility is high.

[0011]

The signal control device is arranged in the connection path between the terminal and the private branch exchange, determines whether the call signal from the terminal requests the intelligent network service, and requests it. For example, the data is transferred to the high-performance processing device via the bus, and if not requested, it is transferred to the private branch exchange device via the connection path. When a call signal requesting an intelligent network service is transferred from the signal control device via the bus, the high-performance processing device takes in the call signal, requests the procedure and data necessary for realizing the intelligent network service, and then I will send it back to the signal controller via the bus.

The signal controller uses the procedure and data returned from the high function processing unit via the bus to realize the intelligent network service requested for the call. The signal control device and the high-performance processing device are characterized in that they are provided externally to the private branch exchange device.

[0013]

1 is a block diagram showing a basic embodiment of the present invention. In the figure, 21 is a moving communication terminal (mobile terminal), 22 is a radio base station apparatus, 23 is a communication terminal, 2
Reference numeral 4 is a signal control device, 25 is a private branch exchange device, 26 is a high function processing device, 27 is a public network, and 28 is a high speed bus.

As can be seen in FIG. 1, in the present invention, between the private branch exchange 25 and the communication terminal 23, and the mobile terminal 21.
The signal control device 24 is arranged between the radio base station device 22 accommodating the mobile station and the private branch exchange device 25. The signal controller 24 is connected to the high function processing device 26 via a high speed bus 28. The high function processing device 26 stores a signal processing procedure for intelligent network service and a database for intelligent network service. The high speed bus 28 has a speed of several hundred times the signal transmission speed between the private branch exchanges.

The position registration information transmitted from the mobile terminal 21 is transmitted to the signal control device 24 via the radio base station device 22. The signal control device 24 attaches the identification code of the radio base station device and transfers the signal to the high function processing device 26. The high function processing device 26 rewrites the position information of the mobile terminal 21 based on the transmitted signal. In this way, the signal processing device 24 and the high-performance processing device 2 have the function of tracking the destination.
Limited to 6 and deployed.

When attempting to receive an intelligent network service using the communication terminal 23, the communication terminal 2
3 is first received by the signal control device 24, and when it is judged that the signal is to receive the intelligent network service, the signal is sent to the high performance processing device 26. If the intelligent network service is not desired, the signal is transferred to the private branch exchange 25.

The high-performance processing device 26 obtains a required database and signal processing procedure based on the signals sent, and then returns the database and signal processing procedure to the signal processing device 24. The signal processing device 24 performs necessary signal processing according to the transmitted signal processing procedure. Next, the signal processing device 24 transmits the service-processed connection signal to the private branch exchange device 25. The private branch exchange 25 performs only the function of connection processing. Among the intelligent network services, those that require signal monitoring during communication and those that perform communication processing using information on the end of communication perform signal monitoring by the signal controller 24 based on the signal processing procedure.

The functions for managing the position of the mobile communication terminal and providing the intelligent network service are provided in the signal control device 24 and the high function processing device 26, and a signal processing procedure is added to the high function processing device 26. By doing so, it is possible to easily add or change services.

As described above, according to the present invention, since the signal processing for realizing the intelligent network service is completed only by the signal control device 24 and the high function processing device 26, the intelligent network service is provided in the local area. Sometimes no modification of the private branch exchange is necessary. Further, since the service function peculiar to the private branch exchange device is not used, the devices (the signal control device 24 and the high function processing device 26) should be added to any type of private branch exchange device having the basic connection function. This enables location management of mobile terminals and provision of intelligent network services.

Since the signal control device 24 stores basic signal processing functional parts, the intelligent network service can be added or changed only by adding the signal processing procedure and the database area to the high function processing device 26. You can

FIG. 2 is a flowchart showing a signal processing flow of the signal control device 24 and the high function processing device 26 in FIG. This will be described below. A signal for receiving the intelligent service is transmitted from a communication terminal that is going to receive the intelligent service, and the signal control device is constantly monitoring the signal. When the signal is received, the signal is translated, and the signal control device and the high function Determine what is to be processed by the processor.

That is, if the signal is not for receiving the intelligent network service, the signal is restored and transferred to the private branch exchange. If the signal is to receive the intelligent network service, the signal received by the signal control device and the terminal number that received the signal are transferred to the high function processing device via the high speed bus. The high-performance processing device derives the signal processing procedure from the signal type, and
Search and register required data from signal information.

For example, a logical number (personal communication number, toll-free number, virtual private network number) is converted into a physical number. After obtaining the signal processing procedure and the converted data, the high function processing device transfers them to the signal control device via the high speed bus. The signal controller sends the connection number in advance,
It stores basic functions such as communication end report and communication start & end time report. These basic functions are arranged according to the transferred signal processing procedure. On the other hand, the transferred data is processed according to this procedure.

When connecting to the communication terminal via the private branch exchange, a connection signal is sent from the signal controller to the private branch exchange. The private branch exchange connects to a predetermined communication terminal by the transmitted signal. In the processing of intelligent network services including mobile communication services, only the basic connection function is used as the private branch exchange, and other required functions are given to the signal control unit and the high-performance processing unit. Therefore, there is no need to modify the private branch exchange.

FIG. 3 is an explanatory diagram showing details of the signal control device 24 and the high function processing device 26 in FIG. In the signal control device 24 of FIG. 3, 241 is a signal monitoring unit, 24
Reference numeral 2 is a signal synthesis unit, 243 is a control unit, and 244 is a transmission unit. In the high-performance processing device 26 of FIG. 3, 261 is a database and 262 is a control unit.

First, the signal controller 24 will be described.
By making a call from a moving communication terminal, a signal for receiving service is placed on the communication line (mainly the other party's telephone number in a call). The signal monitoring unit 241 separates the signal from the communication line and sends it to the control unit 243. The control unit 243 uses software processing to determine whether or not the service type (type representing an intelligent network service) is to be transferred to the high function control device 26 and processed.

If yes, the received signal is sent by the transmission unit 24.
4 to the high-performance processing device 26 via the high-speed bus 28. If not, the received signal is transmitted to the signal synthesizing unit 242 and transmitted to the private branch exchange 25 via the communication line.

Next, the high function processing device 26 will be described. This device is composed of a workstation including a memory and a control unit, a personal computer having a high-speed CPU, etc., receives a signal taken out by the signal control device 24 via a high-speed bus 28, and services based on the received signal. The database 26 is searched and selected for the signal processing procedure. (Examples of service signal processing procedures include connection number transmission, additional number transmission, signal monitoring during communication, and processing at the end of communication-detailed record)

The high function processing device 26 further converts the received related data into connection information necessary for communication. (For example, in the case of connection to a moving communication terminal, the connection number to the base station to which the moving communication terminal belongs, etc.). The service signal processing procedure and the related data thus obtained are transferred to the signal control device 24 through the high speed bus 28.

Next, in the signal control device 24, the necessary data and the service signal processing procedure are returned from the high function processing device 26 via the high speed bus 28, so that the control section 243 performs the service signal processing procedure by software processing. The data is processed according to the above, and is transmitted to the signal synthesis unit 242. (For example, when a signal of an individual number is transmitted, the individual converts it into a destination telephone number.)

FIG. 4 is a block diagram for explaining the functions of the signal monitoring unit and the signal synthesizing unit in the signal control device. Reference is made to FIG. Signal monitoring unit 2 of signal control device 24
At 41, only the signal is decoded from the communication information and the signal information transmitted to the communication line and transferred to the control unit 243. The signal synthesizer 242 encodes the signal and places it on the communication line.

FIG. 5 is an explanatory view showing a concrete embodiment of the present invention. That is, it is an explanatory view showing an example of communication processing between moving communication terminals. A brief description will be given below with reference to FIG. A: Dialing the other party's number from the moving communication terminal B: Sending the other party's number and terminal number C: Determining whether or not the service should be transferred to the high-performance processing device by the control unit (the other party's telephone number is the moving terminal number) From somewhere, it was determined that the intelligent network service was intended, and it was decided to transfer it to a high-performance processing device.)

D: Authentication is performed from the calling terminal number. From the other party's number, the number of the base station to which the other party belongs and the other party's terminal number are searched. A signal processing procedure for communication service between moving terminals is searched. Procedure (calling the base station of the communication partner by the partner terminal number, securing the channel between the partner terminal and the base station,
The base station number for the private branch exchange is transmitted by the signal synthesizing unit, connection with the partner base station), and these data and procedure are returned to the signal controller.

E: Send a calling signal of the calling party's terminal number to the calling party's base station from the signal monitoring section to the calling party's base station. F: Send a telephone number corresponding to the base station from the signal synthesizing section.

[0035]

According to the present invention, since the signal controller is connected to the communication terminal interface of the private branch exchange, all signals from the communication terminal can be monitored by the signal controller. As a result, it becomes possible for the signal control unit and the high-performance processing unit to have all the processing functions of the intelligent network service. No modification of the private branch exchange or addition of software is required to realize the intelligent network service.
