Abstract

PURPOSE:To apply on-network service to a subscriber housed in an exchange provided with no intelligent network service(IN) function without changing the exchange. CONSTITUTION:A hot line number is generated by detecting call origination of a subscriber 1 at an exchange 2 provided with no IN function. An instruction request message is generated and outputted by sending the hot line number to a main control exchange 4 provided with the IN function, analyzing it and activating the IN of the main control exchange 4, a data base 7 of an additional service processor 6 connected to the main control exchange 4 is retrieved by a caller number in this instruction request message, and it is detected which subscriber group among subscriber groups grouped by category the subscriber 1 originating the call is registered on. Based on this detected information, a message for supplying the on-network service as subscriber service to be realized inside the relevant subscriber group is generated and sent to the main control exchange 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supplying a subscriber service in an electronic exchange system, and more particularly to a VPN (Vir).
The present invention relates to a method of supplying an on-net service such as a connection with a partner by an extension number, which is a subscriber service that can be realized by a virtual private network.

[0002]

2. Description of the Related Art A virtual private network is a telephone network or ISDN (In
integrated Services Digital
A public communication network (Network: Integrated Services Digital Network) is used as if it were a private network constructed exclusively for users such as companies using dedicated lines, and the range of connections is limited to remote branch offices with extension numbers only. It is made to be able to communicate with.

Conventionally, when a subscriber is connected using an extension number, which is one of the on-net services using this virtual private network, the software of the stored program control type electronic exchange accommodating the subscriber is provided with the on-net service. In addition, a program for this is added, and the data referred to by this on-net service program is also stored in advance in each electronic exchange so that the calling subscriber can join which of the subscriber groups grouped by category. It is identified by the on-net service program whether it is registered in the caller group, and the on-net service program refers to the data stored in the electronic exchange to determine the extension number of the other party dialed by the calling subscriber. Converted to a phone number and connected to the other party.

[0004]

In this conventional on-net service supply method, an on-net service program is added to the software of all exchanges supplying the on-net service, and the on-net service program refers to the program. Since the data to be stored must be provided in all the exchanges, not only does the storage capacity of the storage devices installed in these exchanges increase, but also when the data to be referred to is changed or newly added, the maintenance personnel must maintain However, there is a problem in that it requires a lot of man-hours because the data of must be updated accurately.

[0005]

The on-net service supply method of the present invention is a switch that accommodates subscribers and does not have an intelligent network service function, detects a call from a subscriber, and activates a hotline service. A hotline number is generated, and the hotline number is sent to a main control exchange having an intelligent network service function for analysis, and the intelligent network service of the main control exchange is activated to generate and output a command request message. By searching the database of the supplementary service processor connected to the main control exchange according to the caller number in the request message, which subscriber group the calling subscriber among the subscriber groups grouped by category is registered Is detected and this is detected The additional service processor messages for on-net service supply is a subscriber service that is implemented within the subscriber group based on information sent to the generated the main control switch.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

Referring to FIG. 1, which shows a switching system to which an on-net service supplying method according to an embodiment of the present invention is applied, the switching system is such that a specific subscriber who is registered in advance only by calling display of a subscriber 1 is registered. An exchange 2 having a hotline service function unit 3 for controlling a direct connection between them.
A main control exchange 4 having a numerical translation / analysis function unit 8 for translating and analyzing the number received through the exchange 2 and an intelligent network service function unit 5 separated from the software of the exchange, and a database 7 for storing service information. And an additional service processor 6 realized by a non-stop computer. Figure 1
In the figure, one exchange 2 is illustrated as being connected to the main control exchange 4 through a common line signaling network. However, usually, a plurality of exchanges 2 are connected to the main control exchange 4 in order to share equipment. It

FIG. 2 is a diagram showing the flow of signals and messages in FIG. The operation will be described below with reference to FIGS. 1 and 2.

When the subscriber 1 picks up the handset, a loop signal is sent to the exchange 2. When the exchange 2 receives the loop signal from the subscriber 1 and identifies that the subscriber 1 is a pre-registered subscriber of the hotline service, the hotline service function unit 3 is activated. The hotline service function unit 3 generates a hotline number for routing to the main control exchange 4 which is set in advance, for example, an access number such as "0088", and the main control exchange 4 receives the No. 7 Send a signal called information flow through the common line signaling network. Parameters of this signal include dialed number, caller number, caller attribute, and the like.

The exchange 2 and the main control exchange 4 do not necessarily have to be a common line signaling network.
MFC (Multi Frequency Compe
Led) or DP (Decadic Pulses)
e) with ANI (AutomaticNumber)
It is sufficient that the caller ID can be transmitted and received between the exchange 2 and the main control exchange 4 by using a signal system such as r Identification.

By the above-mentioned method, the call from the exchange 2 having no intelligent network function is guided to the main control exchange 4 by using the hot line function.

Numerical translation / analysis function unit 8 of the main control exchange 4
Translates and analyzes the hotline number contained in the signal received from the exchange 2, and activates the intelligent network service. The intelligent network service function unit 5 is No. A command request message, which is a type of message called an information flow, is generated according to the format of the transaction function application unit defined by the common line signaling method. 7 Sends to the supplementary service processor 6 through the common line signaling network to activate the on-net service program.

The supplementary service processor 6 knows the telephone number of the subscriber 1 from the caller number, which is a parameter of the received command request message, and searches the database 7 with this telephone number to group the categories. To know to which subscriber group the calling subscriber is registered among the subscriber groups. This group of subscribers is called an on-net group, for example VP
N (Virtual Private Network) and WAC (Wide Area Ce)
There is a group of subscribers trying to provide on-net services such as ntrex). Centrex services are generally services provided by private branch exchanges,
For example, functions such as extension mutual call, calls from outside line to extension line, hold, transfer, etc. are to be performed by a central office switch without a private branch exchange, and what is performed across the stations is called WAC.

The on-net service program activated by the supplementary service processor 6 can supply various on-net services to the subscriber 1 by issuing various messages to the main control exchange 4. That is, various application services are controlled by the supplementary service processor 6 without the exchange 2 being completely aware of what kind of service is being performed, which is the basic concept of the intelligent network.
The type of on-net service depends on the conditions (dialed number,
Subscriber attributes, etc.) become parameters and are included in the command request message from the main control exchange 4 to the supplementary service processor 6 and sent. Additional service processor 6
However, by analyzing the data possessed by each subscriber and the parameters of the message sent from the main control exchange 4, it determines which service is to be activated and sends a message suitable for it to the main control exchange 4.

For example, when a connection is made with the other party by the extension number, the supplementary service processor 6 sends a "message for sending an announcement and receiving a numeral" to the main control exchange 4, whereby the main control is performed. The exchange 4 sends the subscriber 1 an announcement "Please dial the extension number", and the supplementary service processor 6 receives the DTMF signal dialed by the subscriber 1 via the main control exchange 4. After receiving this extension number, the on-net service program refers to the data stored in the database 7 of the additional service processor 6,
The extension number based on the received DTMF signal is converted into a general telephone number and connected to the other party.

A call is set up by the supplementary service processor 6 whether it is an extension mutual call or a call to a public network. In this case, it is necessary to distinguish between an extension number and a public number. The supplementary service processor 6 makes this distinction by sending a predetermined access code to the supplementary service processor 6.

The identification of whether the outgoing call is a hotline or an on-net service is determined by the timeout of the message "please dial a number" from the supplementary service processor 6 in FIG. In this case, if the subscriber 1 hears the announcement and then nothing is dialed for several seconds, the main control exchange 4 reports to the supplementary service processor 6 that nothing has been received, and the application program of the supplementary service processor 6 is notified. By sending the hotline number corresponding to the subscriber 1 extracted by the above to the main control exchange 4 as a call setup message, the intended operation is performed in the original hotline.

Further, the subscriber 1 dials a predetermined access number even after the on-net service is activated by the additional service processor 6 and then dials a telephone number in a general public network. Additional service processor 6 through main control switch 4
It receives this and can connect to any subscriber of the public network according to the dialed digits.

[0019]

As described above, the present invention provides a hotline service, which is a general service provided to an exchange, to a subscriber accommodated in the exchange having no intelligent network service function or on-net service function. By using the intelligent network service function deployed to other stations,
The system can be constructed economically and efficiently without changing the existing exchanges, and a high level service called on-net service can be provided.
