Abstract

PURPOSE:To make introduction of new service easy and to make transfer service required in case of moving of the residence of a user easy by providing a data file corresponding to proper user's number given to users individually, sending the user's number to an exchange when originating and making call connection by retrieving the data file. CONSTITUTION:Specific user's numbers are provided to users, and a data file 3 is made up of memories provided in corresponding to user's numbers. Unlike a telephone set number given to a terminal, the user's number is a number given to individual user who changes the position at all times. The data file 3 stores information related to a user such as terminal number of an exchange to which the terminal (telephone set) used for communication by the user, the state of subscriber, charging information, service class etc. to correspond to the user's number. A signal ds is an information signal that includes at least terminal number of the terminal of an exchange to which a terminal used by a user for communication, and read out from the data file 3 to an exchange 2. Proper user's number pn is transmitted from the exchange 2 to the data file 2 to correspond to the user.

Description

[Detailed Description of the Invention] [Summary] By creating a data file corresponding to a unique user number assigned to each individual user, and sending this user number to the exchange when making a call, the data file is indexed. Performs call connection processing.

[Industrial application field]

The present invention relates to a personal switching system that performs switching connections for telephone users such as telephone exchanges. The personal switching system of the present invention facilitates the introduction of new services by using a data base provided for the user for all call processing, and easily achieves transfer services as the user moves from place to place.

[Conventional technology]

In the conventional switching system, a terminal number (LEN: subscriber equipment number) assigned to a terminal of an exchange and a user number assigned to a terminal connected to that terminal are made to correspond to one lamp. Then, a memory for storing a data file indexed by the terminal number of the exchange is provided in the exchange, and various information related to the user such as the user number, line status display, service class, etc. is stored in this memory in correspondence with the terminal number. , this information is used in the exchange process.

In other words, when making a call, the exchange scans the terminal status and, if it detects a call, accesses the memory corresponding to that terminal and records the user's status, service class, etc. (for example, if the connection is not made because the fee has not been paid). and perform call processing. In addition, when a call is received, the destination terminal number of the exchange is gelled from the destination terminal number obtained from the calling party or the previous station through translation processing (table indexing), and the terminal number of the destination terminal is retrieved from the memory corresponding to that number. It knows the status (for example, line busy) and performs necessary call processing.

[Problem that the invention seeks to solve]

In conventional switching systems, information about a user terminal exists only in the memory of the switch in which the terminal is housed. Therefore, for example, when providing a call forwarding service, data such as the forwarding destination terminal user number is written in the memory of the exchange that accommodates the receiving terminal, and when a call is received at the receiving terminal, it is forwarded to the forwarding destination terminal by re-dialing. are doing.

In such a conventional call forwarding service, if you want to transfer a call from the destination terminal to another location, additional destination terminal data will be written to the memory of the exchange that accommodates the destination terminal. In this case, not only calls transferred from the original receiving terminal but also calls arriving at the destination terminal itself are transferred to the further destination terminal, which is extremely inconvenient.

In this way, in the conventional system, users are attached to the terminals of the exchange, and all information about the users is concentrated in the accommodating subscriber exchange, which has the problem of greatly restricting the degree of freedom in providing services. .

Therefore, an object of the present invention is to eliminate the telephone numbers assigned to conventional telephones, assign a unique user number to each user, and include the terminal number on the exchange side in the data file corresponding to this user number. The purpose of the present invention is to provide a personal exchange system with a higher degree of freedom based on the concept of storing and managing various types of information, including information, and performing all call processing based on this information.

[Means for solving problems]

FIG. 1 is a block diagram showing an exchange system implementing a personal exchange method according to the present invention. In FIG. 1, ■ is a terminal, 2 is an exchange, and 3 is a data file common to the entire exchange system. Although only one terminal l is shown in the figure, a large number of terminals are actually accommodated in the exchange 2. Exchange 2 is a communication path! 421, a scanning device 22, a central control device 23, a memory 24, etc., and the memory 2
4 stores data regarding the status of the terminals of the exchange in which the terminal 1 is accommodated (vacant and occupied).

The data file 3 includes a memory that assigns a unique user number to each user and is provided corresponding to the user number. This user number is different from a telephone number given to a conventional terminal, and is a number given to an individual user who constantly moves. Data file 3 corresponds to the user number, and information corresponding to the user such as the terminal number of the exchange to which the terminal (telephone) that the user is currently using for communication is connected, subscriber status, billing information, service class, etc. is written tα.

Note that ds is an information signal that is read out from the data file 3 to the exchange 2 as an information signal that includes at least the terminal number of the terminal of the exchange to which the terminal used for communication by the user is connected. Further, pn is a user number unique to each user and is transmitted from exchange a2 to data file 3.

[For production]

When making a call, the calling party's subscriber number is sent from the calling terminal to the exchange. The exchange accesses the data file, uses the other party's user number as an index, reads information necessary for call processing, such as the incoming terminal number, line availability/blockage, etc., and uses that information to respond to the other party's current response. A call connection is made to the terminal of the exchange that is connected, thereby connecting the originating user and the terminating user.

〔Example〕

Hereinafter, the personal exchange system of the present invention will be explained with reference to the drawings. The configuration of the exchange system that performs this personal exchange method is the same as that shown in FIG.

FIG. 2 is a sequence diagram showing an example of a normal operation for connecting a party user and a called party. In Figure 2, when a party user makes a call using terminal l, exchange P9 with terminal l.
．． A loop is closed between the two.

The scanning device 22 scans the terminal state and, when detecting a call, notifies the central control device 23 of the call.

The central controller 23 writes the calling terminal busy information in the memory 24 and also outputs the dial tone D via the communication path Nil 21.
Send Tl to the originating terminal. The party user opens it and sends his/her own user number to exchange 2. Then, the central control device 23 accesses the data file 3 using this own user number as an index, and receives information such as the service class, 11 (1 identification number, etc.) regarding the own user number from the data file 3.

Then, the central control device 23 sends a dial tone DT2 to the party user to prompt the party user to send out the password. When the party user sends the PIN number, the central control device 23 checks the PIN number obtained from the data file 3 and the PIN number sent by the party user. In the method of the present invention, a party user can make a call from any terminal, and if the call is made as is, the party user will be identified on the exchange side at the time of the call.
In other words, it is not possible to confirm whether the party user is really the user, which causes problems with billing, etc.

When the passwords match, the central control unit 23 sends and writes the calling terminal number to which the calling terminal is connected to the data file 3, and sends a dial tone DT3 to the party user via the communication path m21. In response, the party user sends the other party's user number to the exchange 2. The central control device 23 accesses the data file 3 using the other party's user number as an index, receives information such as the accommodating terminal number and status of the other party's user number, and thereby determines whether the called party's user is using the terminal. The output terminal of the exchange to which the terminal is connected is specified, and the status of the output terminal, such as availability or occupancy, is read from the memory 24.

If the output terminal is empty, the central controller 23 connects the communication path network 2
In one output, the RBT is sent to the party user and the ring tone is sent to the called user. When the called party answers, a loop is closed between the called terminal and the exchange 2, the scanning device 22 detects it, the central controller 23 thereby sets the contents of the called terminal's memory as called called terminal busy, and The data file 3 is accessed and the status of both the party user and the receiving user is set to busy.

When the originating/terminating user disconnects, the loop between the terminal and the exchange is opened, this is detected by the scanning device 22, and the central controller 23 stores all seven destination terminal information in memory 24 and the originating/destination terminal information in the data file 3. Clear the recipient user information.

FIG. 3 is a diagram showing an operation sequence for registering a terminal number to which a newly used terminal is connected when a user moves to another location and changes the terminal used for communication. In FIG. 3, in response to a call from a party user, the central control unit 23
The sequence up to the return of DT3 is the same as that shown in FIG. 2, and the central controller 23 inputs the originating terminal number into the data file 3 and sends DT3 to the originating terminal. The party user sends the registered special number to the central control device 23 in response to this DT3. As a result, the central control unit 23 accesses the data file 3, and from then on, when there is an incoming call to all user numbers, the incoming call is processed to the calling terminal number specified in nn written in the data file 3. . In this way, after location registration,
When an incoming call is received, the newly registered terminal becomes the terminal to which the terminal used by the user is connected, and the call is connected to that terminal.

FIG. 4 is a diagram showing an operation sequence when the destination terminal is a 4iT intra-exchange. In FIG. 4, the sequence is the same as in FIG. 2, from when the central controller 23 returns DT3 in response to the originator's call, and in response, the originator sends the other party's user number to the exchange 2. be.

The central control unit 23 accesses the data file 3 using the other party's user number as an index, receives information such as the accommodation terminal number, status, and whether it is a private branch exchange for the other party's user number, and thereby determines the output terminal of the called party. is identified, and the state of the output terminal, such as availability or blockage, is read from the memory 24.

If the output terminal is empty, the central control bag η23 sends a ringing tone to the destination terminal (private branch exchange) via the communication path network 21.

When the private branch exchange automatically answers, the scanning device 22 detects it and the central control unit 23 accordingly sends the called party number to the private branch exchange. As a result, the private branch exchange connects the call to the terminal of the accommodated user.

〔Effect of the invention〕

According to the present invention, the user is no longer tied to the terminal of the exchange, so the degree of freedom regarding the service is increased, and this allows the user to, for example, receive calls from any location by registering a special number. It becomes easy to introduce new services such as being able to receive calls and rejecting call connections after the specified time.
