Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a telephone switching system in which switching connections to telephone terminals can be effectively controlled on an individual basis.

(Prior Art) Conventionally, general telephone exchange systems have been operated using identification information for each telephone terminal called a telephone number. Furthermore, with the development of an information and communication society, many telephone terminals have become widespread, but the reality is that many of these telephone terminals are usually shared by multiple users.

By the way, if we pay attention to how telephones are used, we often find that we want to call a specific individual directly. In other words, when you make a call to a telephone terminal identified by a telephone number, if the person you want to call is absent, the call request cannot be fulfilled even if another user responds to the call request. There are many things that happen. In such a case, the calling party is wasted the call, and the receiving party is inconvenienced.

Therefore, recently, it has been considered to control calls to individuals using a telephone number that specifies a telephone terminal and personal information that specifies the user of that telephone terminal.

In other words, for each telephone terminal, the user's information (user number)
and register presence/absence information. If only a telephone number is input from the telephone terminal of the calling party, a call request is issued to the telephone terminal specified by the telephone number.

Also, after entering the above phone number, the person requesting a call (
When information (user number) identifying a user (user) is input, the presence/absence of the individual identified by the user number of the telephone terminal identified by the telephone number is checked from the registered information; It has been considered to issue a call request to the telephone terminal only if the individual is available.

The control processing function that enables telephone connections on an individual basis prevents unnecessary calls, compared to conventional systems that could only control telephone connections on a telephone terminal basis. Also, there are effects such as no more bothering the other party.

(Problem to be Solved by the Invention) However, in such a telephone switching system that allows call connection on an individual basis, it is necessary to prevent the occurrence of an unwanted call request to a telephone terminal for an individual who is unable to respond. can only be done. And the question remains as to the initial request to talk to that particular individual.

The present invention was developed in consideration of these circumstances, and its purpose is to enable control of telephone call connections on an individual basis, and to effectively satisfy telephone call requests for individuals. Our goal is to provide a telephone exchange system that can

[Structure of the Invention (Means for Solving the Problems) The present invention provides a telephone exchange that accommodates a plurality of telephone terminals with a customer data storage section in which personal information of the user is registered for each of the above-mentioned telephone terminals. , the above-mentioned telephone terminal includes, for example, an IC into which an IC card in which personal information is registered is set.
A personal information input section such as a card interface is provided, and the personal information entered into the telephone terminal via this personal information input section is transmitted from the telephone terminal to the telephone exchange, and this personal information and the personal information are input. Information on telephone terminals that can be used by the individual is registered in the customer data storage section according to the information on the telephone terminals.

When a request for a call to an individual is made to the telephone terminal for a person who does not use the telephone terminal, the customer data storage unit is referred to to check whether or not there has been a change in the telephone terminals available to the individual; The present invention is characterized in that the telephone exchange is provided with means for notifying the calling party of information on the telephone terminal to which the change has been made if there is a change.

(Function) According to the present invention, the information of the user is registered as customer data for each telephone terminal housed in the telephone exchange, and when the user changes his/her location, the telephone number of the new user is registered as customer data. By providing personal information from the terminal using, for example, an IC card in which personal information of the user is registered, information on telephone terminals available to the user is registered as customer data to be changed.

Therefore, when a request for a call to an individual is made to a telephone terminal in which the user's personal information is registered as customer data, for example, a telephone number is entered followed by a personal number. When the customer data storage unit is referred to and the user identified by the personal number of the telephone terminal identified by the telephone number (
It is checked whether there has been a change in the telephone terminals available to the individual (individual). If there is a change in the telephone terminals available to the identified individual as described above, the caller will be notified of the information on the mll sales destination telephone terminal.

Therefore, the caller is able to know that the individual requesting a call is not present, and also know the means of calling that individual. As a result, it becomes possible to make a call to the changed telephone terminal if necessary.

Further, at this time, call connection based on a call request directed to an individual to the previous telephone terminal is prohibited, and no call is connected to the telephone terminal, so that unnecessary calls can be avoided. At the same time, it is possible to prevent inconvenience caused to the other party due to an unwanted call connection.

Furthermore, telephone users can very easily modify customer data that identifies telephone terminals available to them by simply inserting, for example, an IC card with personal information registered into an available telephone terminal at that time. , it is possible to effectively deal with call requests addressed to the user.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram illustrating the concept of the embodiment system, where ■ is a telephone exchange, and 2 is a plurality of telephone terminals housed in this telephone exchange l. These telephone terminals 2 are comprised of so-called multi-function telephones equipped with a display, ordinary rotary dial telephones, bushhorn telephones, and the like. The telephone exchange 1 is also connected to other telephone exchange systems via central office lines.

Therefore, the telephone exchange 1 is provided with an exchange control section 1a that controls call connections, and a customer data management section 1b.
1 customer data storage section 1c is provided. This customer data storage unit 1c stores personal information (ID number, etc.) of each of the above-mentioned telephone terminals 2 housed in the telephone exchange 1, and of the users (usually a plurality of users) of that telephone terminal. It is.

In addition, when the telephone terminal 2 available to the telephone terminal user changes from the telephone terminal that the telephone terminal user usually uses to another telephone terminal, for example by moving the user's location, the customer data management unit 1b transfers the information as described above. It has a function of correcting data input from the previous telephone terminal 2 and registered in the customer data storage section 1c. Under the control of the customer data management section 1b, when a call request to an individual is made to the telephone terminal 2, the customer data storage section 1c is referred to to determine whether the individual is able to respond or not. If so, it is possible to check which telephone terminals are available to the individual.

Therefore, the switching control section 1a controls the call connection based on the management information in the customer data management section 1b. If there is a change in the telephone terminal available to the individual who has made the call request, information on that telephone terminal is notified to the caller.

Information on telephone terminals available to the user is provided as follows. That is, the telephone terminal 2 is provided with an IC card interface (personal information input section) 2a for inputting personal information registered therein from, for example, an IC card 3 carried by the user. The above IC card 3 is connected to the IC card interface 2a.
When set to , the personal information (ID number) shown there is read and the information is given to the telephone exchange 1.

The customer data management unit 1b corrects the customer data of the corresponding individual as described above, according to the personal information given from the telephone terminal 2 in this way and the information of the telephone terminal to which this personal information is given. Become. As a result, the call connection for the call request addressed to that individual is controlled as described above. This eliminates the waste of call connection for the call request, and provides effective telephone service.

Next, details of this system will be explained. FIG. 2 is a schematic diagram of a telephone exchange l in a telephone exchange system to which the present invention is applied. A plurality of telephone terminals 2 accommodated in this telephone exchange 1 are each connected to a predetermined number of line cards 11 of the exchange 1. Typically, 8 to 16 telephone terminals 2 are connected to one line card 11.

Further, the trunk card 12 is used to connect a central office line, and communication paths are established from this trunk card 12 to other exchange systems via the central office line.

The time switch circuit 13 forms a communication path between the line card 11 and the trunk card 12 by, for example, exchanging time slots under call connection control. A communication path is set up between the terminal and the conference circuit 15.

Each of these units operates in response to an operating clock from the clock generator 16, and is connected to a central control unit (usually referred to as CC) via the l1017.
Each operation is controlled under the control of 1g.

Here, the central control unit (CC) 1g includes a CPU 18a that controls its overall operation, a memory 18b that stores control programs and various control data, a floppy disk device (FD) 18c as an external storage device, and an input/output device 1.
8d, and data terminals 18e and the like used for inputting and outputting data necessary for exchange control are connected to each other via a bus 18f. Via this data terminal 18e, human power such as maintenance management information, telephone number information set for each telephone terminal 2, information indicating the type of telephone terminal 2, and customer data to be described later is performed.

On the other hand, the telephone terminal 2 connected to the telephone exchange 1 (line card 11) is, for example, a multifunction telephone with a display as shown in FIG.

This multi-function telephone consists of a housing 21 containing the main body and a handset 22, and a liquid crystal display 23 and a dial key pad 24 on the front of the housing 21.
, various function selection buttons 25, etc. These function selection buttons 25 include a soft key group 25a to which various software processing functions are assigned, a fixed function key group 25b1 to which telephone service functions such as hold and transfer are fixedly assigned, and a telephone service key group 25b1 to which telephone service functions such as hold and transfer are fixedly assigned. It consists of a variable function key group 25c to which functions are programmably assigned. Incidentally, a display device 26 formed of a light emitting diode or the like provided corresponding to the variable function key group 25c displays the operating state of the function function.

However, the housing section 21 of the multi-function telephone is provided with an IC card mounting section, although not particularly shown. When the IC card 3 carried by the telephone user (individual) is set in the IC card mounting section, the IC card 3
For example, data such as an ID number indicating personal information is input and output between the computer and the computer.

Incidentally, this IC card 3 has an I/O card as shown in FIG. 4, for example.
10 interface 31 to the bus 32 connected to the C
PU33. RAM34. ROM35. Program ROM
36 etc. are connected to each other.

Personal information of the card owner is fixedly registered in the IC card 3 as an ID number, for example, in the ROM 35, and is read out as necessary under the control of the CPU 33. This ID number is then output to the telephone terminal 2 or the like via the I10 interface 31.

FIG. 5 shows an example of the structure of the main body of the telephone terminal (multifunctional telephone) 2 having the external structure as described above. The telephone terminal 2 is roughly divided into a signal transmission system a, an audio system C1, an operation system C1, and a personal information input system d consisting of an IC card interface section.

The signal transmission system a transmits signals to and from the line card 11 of the telephone exchange 1 via the telephone line, and assembles transmitted signals and disassembles received signals. The voice system sends and receives voice signals to and from the exchange 1 via this signal transmission system a, and the data processing terminal 5 connected to the telephone terminal 2 also communicates with the exchange 1 via this signal transmission system a. Data signals are sent and received between the two. Note that the data processing terminal 5 is connected to the telephone terminal 2 via a communication interface (Ilo) 8 such as RC232c.

Here, the signal transmission system a includes a transmission register a1 and a reception register a2, and receives a transmission audio signal V, transmission data D, and various transmission control signals C given to the transmission register a1.
are assembled into a predetermined frame configuration. The transmission signal assembled in this transmission register a1 is sent to a parity adding circuit a3.
After reading out the signal and adding a parity signal, it is converted into a diphase signal via the NRZ/DP conversion circuit a4.

This diphase-converted transmission signal is then transmitted from the hybrid circuit a5 to the exchange 1 via the telephone line.

Further, a signal transmitted from the exchange 1 and received via the hybrid circuit a5 is converted into an NRZ signal via the DP/NRZ conversion circuit a6, and this signal is stored in the reception register a2. The reception register a2 decomposes the reception signal into a reception audio signal V, reception data D, and various reception control signals C.

The frame detection circuit a7 detects a frame synchronization signal from the received signal, and the timing control circuit a8 controls the operation timing of the telephone terminal 2 in synchronization with this frame synchronization signal. Further, the window control circuit a9 receives this timing control and controls the NRZ/D.
It controls the conversion operations of the P conversion circuit a4 and the DP/NRZ conversion circuit a6, respectively.

On the other hand, the audio system inputs and outputs audio signals via the aforementioned handset 22, speaker b1, etc., and is configured by connecting these to a codec b3 via an amplifier b2. Then, a transmission signal input as voice from the handset 22 or the like is encoded into a transmission audio signal V, which is output to the transmission register al.

Further, the received audio signal V inputted from the receiving register a2 is decoded via the codec b3, and the audio signal is output as a received signal from the speaker b1 or the like.

Further, the operation system C includes a display control section c1. c2, and an I10 interface 03 for inputting operation information of the various keys 24 and 25 described above. Furthermore, the personal information input system (IC card interface unit) d is configured to include a reader/writer d1 for the IC card 3 and an I10 interface d2.

Each of these parts is connected to the CPU via the data bus 2a.
2b, ROM2c, and RAM2d.
Each state is controlled.

Furthermore, control information, etc., which are inputted via the operation system C and the personal information input system d, processed by the CPU 2b, etc., and transmitted to the telephone exchange 1 are transmitted from the data bus 2a via the transmission shift register. is applied to data buffer a1. Further, the control information transmitted from the exchange 1 and received by the reception data buffer a2 is taken into the CPU 2b from the reception shift register via the data bus 2a. It is used for controlling its operation and displaying various services and messages.

On the other hand, the line card 11 of the telephone exchange 1, which transmits signals to and from the telephone terminal 2 thus constructed, is constructed as shown in FIG. 6, for example.

This line card 11 includes the central control unit (CC) 1
Its operation is controlled while exchanging data with G, and signals are transmitted between the telephone terminal 2 connected via the telephone line and other line cards 11 etc. via the time switch circuit 13. It is used to transmit signals between

That is, the transmitting/receiving circuit 11b connected to the telephone line via the hybrid circuit 11a has a transmitting frame register li.
The transmission signal sent from e is converted to NRZ/DP and sent to the telephone line, and the reception signal received via the telephone line is converted to DP/NRZ and taken into the reception frame register lid. Note that the synchronization signal detection circuit 11e detects the synchronization signal in the received signal and controls the signal input timing to the reception frame register lid.

The reception frame register lld decomposes the received data into the aforementioned audio signal V, data D, and control signal C, and stores them in reception registers llf, 11g, and 11h, respectively. The multiplexer 111 receives the above-mentioned receiving register 11r in a time slot to be described later.

The audio signal V or data D stored in 11g is selected and applied to the time switch circuit 13 via the PCM highway llj. Under time-division exchange control by the time switch circuit 13, the voice signal V and data D are applied to the time slot of the called party.

The time-division exchanged audio signal V and data D are
From the above PCM highway 11j to multiplexer Llk
register 11a+, U at a predetermined time slot via
n and is applied to the transmit frame register llc.

The time slots for controlling the operations of the multiplexers 11i and 11 are defined by a comparator llp that compares the count value of the counter Ilo with the unique address set in the line card 11.

That is, the counter llo inputs a frame synchronization signal given from the central controller 13 via the frame signal line 11q, and counts the clock signal given from the clock generator 1B via the clock signal line 11r. . Based on this count value, the PCM highway 11j
Each time slot of voice and data transmitted in a time-sharing manner via multiple line cards 11 and trunk circuits 1
2 are managed respectively. The comparator 11p determines whether the time slot counted by the counter llo is the time slot assigned to itself, and sends a signal to the PCM highway llj and takes in a signal from the PCM highway 11j. There are things.

On the other hand, the control signal from the telephone terminal 2 requested to the register llh is transmitted to the C bus connected via the internal bus lls.
Incorporated into P Ullt. Further, the control signal to be sent to the telephone terminal 2 is sent from the CPU lit to the register f.
lu, and the above-mentioned transmit frame register ll
given to c. Note that the memory llv is the CPU
It stores not only the operation program of the lit, but also various control data.

The CPU llt is connected to the central control unit 18 via the data highway llx from l10ily, and sends and receives various control signals to and from the central control unit 18 to control its operation. .

Voice signals and data are transmitted and received between the telephone terminal 2 and the telephone terminal 2 via the line card 11 configured as described above, and the telephone exchange 1 controls the call connection and voice/data exchange. ing.

The feature of this system is that the memory 18b of the central control unit 18 is provided with a customer data storage section 1c configured as shown in FIG. 7, for example. Note that the customer data management section 1b that manages the customer data storage section 1c and the time switch circuit 13
to drive the audio signal via the PCM highway llj.
The exchange control unit 1c that controls data exchange connections is realized as a processing function or the like in the CPU 18a of the central control unit 18.

This customer data storage unit 1c registers and manages the personal information of each user for each telephone terminal 2 accommodated in the exchange 1. That is, as shown in FIG. 7, for each telephone terminal 2 connected to each boat, information indicating its type, a telephone number assigned to the telephone terminal 2, and an ID number indicating the personal information of the user are fixedly stored. registered as customer data.

The ID number indicating the user's personal information is managed with an additional number unique to the telephone terminal. Specifically, the telephone terminal 2 connected to the boat (Ni2B) of the exchange 1 is a telephone with a display, the telephone number assigned to it is r2312J, and there are two users. The ID number of the user assigned the additional number "1" is r86010010J.
, the customer data indicates that the ID number of the user assigned the additional number "2" is r82011010J.

Additionally, this customer data storage unit 1c contains temporarily assigned customer data such as information on whether the user is available to respond (absence information), and the user's ID number that is set from time to time. It is now registered. This-
Temporary customer data is provided when the aforementioned user changes his or her location by inserting the IC card 3 carried by the user into the telephone terminal 2 of the user's new location.

That is, when the IC card 3 is set in the destination telephone terminal 2, the personal information (ID number) is read from the IC card 3 into the telephone terminal 2. The personal information is then given from the telephone terminal 2 to the customer data management section 1b of the exchange 1. Then, the customer data management section 1b
In addition to recognizing the D number, the information on the telephone terminal 2 into which the ID number has been input is recognized as a port number, etc. Then, the input ID number is registered as temporarily assigned customer data of the telephone terminal connected to the corresponding port. Furthermore, in addition to registering such temporarily allocated customer data, the customer data management unit 1b checks the telephone terminal to which the ID number is fixedly registered, and records "absence" information corresponding to the personal information of that telephone terminal. You have set up temporary assigned customer data.

Specifically, when a user (ID number: 82011010) of the telephone terminal 2 to which the telephone number r2312J has been assigned changes his/her location and sets the IC card 3 into the telephone terminal 2 to which the telephone number r2B21J has been assigned, the As shown in Figure 7, the above ID number r 82011 is temporarily assigned customer data for the telephone terminal 2 connected to port i.
010J is registered and the ID number r 82011010
A prohibition flag rXJ indicating absence is registered as temporarily allocated customer data in the information for the individual of the telephone terminal 2 in which J is fixedly registered.

As will be described later, when a call request is made on an individual basis, the call connection is controlled by referring to such temporarily allocated customer data under the control of the customer data management section 1b.

Therefore, when a request for a call by inputting a telephone number occurs, the exchange control section 1a stores the customer data storage section 1c.
The port number of the telephone terminal to which the corresponding telephone number is assigned is checked, and a call is made to the telephone terminal 2 connected to that port. Through this call connection, call requests for each telephone terminal are controlled.

On the other hand, if a phone number is entered followed by an additional number that specifies the user, the phone number will be searched as described above and the individual specified by that additional number will be found. You can check whether it is or not. If there is an individual identified by the additional number, the time-allocated customer data is referred to to check whether or not that specific individual is available for response.

If the specified individual is available for response by such a search of the customer data storage unit 1c, the boat number to which the specified telephone terminal 2 is connected is obtained, and the telephone terminal 2 connected to the port is A call connection is made.

In contrast, if the specified individual is absent (unable to respond), the prohibition flag in the time allocation customer data "
×”, the call connection is aborted. Then, instead of this, an ID number specified by the additional number is obtained from the customer data, and temporarily allocated customer data is searched according to this ID number.

When the corresponding ID number is obtained through this search process, information (telephone number, etc.) about the telephone terminal in which the ID number was registered is obtained, and the information is notified to the caller.

This notification of the destination telephone number is sent, for example, as the aforementioned control signal from the line card 11 to the calling side telephone terminal 2.
Transmit phone number information to. The telephone number is then displayed on the liquid crystal display 23 of the telephone terminal 2 together with the message information.

The individual then moves further and uses the available telephone terminal 2.
If there is a change in the ID number, the ID number will be registered in the same way for the new phone terminal, and this ID number will be registered first.
The customer data is deleted from the telephone terminal to which the number was temporarily assigned.

and if the individual returns to his or her original location, the same <
The ID number is entered using the IC card 3, and the temporarily assigned customer data (
ID number) and the prohibition flag "x" are deleted.

Based on such time allocation customer data, call connections for individual call requests are controlled.

As described above, according to the present invention, information on telephone terminals 2 available to each individual can be effectively managed, and call connections for call requests addressed to that individual can be effectively controlled. In addition, information on telephone terminals that can be used by each individual can be obtained very easily by the simple operation of setting the IC card 3, which the individual carries individually, into the telephone terminal 2, in which personal information is registered here. Can be done.

If a call request is made to an individual and the above-mentioned prohibition flag rXJ is set as information about the user of that telephone terminal, the information of the telephone terminal to which the person has moved will be notified instead of canceling the call connection. Therefore, it becomes possible to make a call to the telephone terminal at the destination as needed. Alternatively, if a telephone transfer function is provided, it is possible to transfer the telephone number according to the transfer instruction.

As a result, it becomes possible to appropriately handle call requests to individuals as necessary.

Therefore, according to the present invention, it is possible to effectively perform telephone call connection control on an individual basis and to effectively satisfy call requests addressed to individuals.

Note that the present invention is not limited to the embodiments described above. Here, the explanation has been made assuming that there are two users of the telephone terminal, but it goes without saying that the number of users of the telephone terminal may be one, and it goes without saying that the number of users may be 3 Å or more. In addition, if the telephone terminal 2 is not equipped with a display,
For example, it is also possible to notify information about the destination telephone terminal by voice synthesis. It goes without saying that the number of telephone terminals 2 accommodated in the telephone exchange 1 is not particularly limited. In addition, the input of personal information is not limited to the input of the IC card 3, but also the input of the function selection button and the input using the keypad.
This can also be done by inputting the D number. others,
The present invention can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] - As explained above, according to the present invention, it is possible to control call connections on an individual basis in a very simple manner, eliminate unnecessary calls, and effectively satisfy call requests to individuals. It has great practical effects, such as being able to.
