Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a message registration method that can easily register various types of message information given to telephone terminals in an electronic exchange system.

[Technical background of the invention and its problems]

As various service functions for telephone terminals in electronic switching systems, busy interrupt functions, absentee guidance services, etc. have been developed.

The busy interrupt function is provided to telephone terminal B via exchange A, for example, as shown in FIGS. 13(a) to 13(c).

When telephone terminal R calls telephone terminal C during a call between telephone terminals C and D, if necessary, the telephone terminal's telephone line is temporarily put on hold and the telephone line between telephone terminals C and D is connected. The telephone terminal B interrupts the call between the terminals 8 and 0, and then, as the call between the telephone terminals C and D ends, the telephone terminal B
, C is restored. Such a busy interrupt function can be effectively used, for example, to communicate urgent requirements.

Furthermore, the absentee guidance service uses the voice mail device E as shown in FIGS. 13(d) and (e). For example, when the telephone terminal B becomes absent due to going out, The place of going out, the time of return, etc. are registered as a message, and when the telephone terminal B is called, the calling telephone terminal F is connected to the voice mail device E and the registered message is transmitted to the telephone terminal F. It was designed to do so.

However, the above-mentioned busy interrupt function has the biggest drawback of interfering with communication with the person on the other end of the call, and in order to provide an absentee guidance service using the voicemail device E, the exchange system would be quite expensive. There was a problem that happened. Although various other telephone service functions have been proposed, the complexity and cost of the switching system have unavoidably increased.

On the other hand, a service function has been considered in which the telephone terminal itself is provided with a display G as shown in FIG. 14 to display call time, call charges, and the like. In particular, as display devices become cheaper and more functional, it is believed that telephone terminals incorporating display devices with the above-mentioned functions will become increasingly popular.

Therefore, if such a display G is used to display various messages, it is believed that the service functions of the exchange system can be further enhanced and communication can be significantly improved. However, there remains a problem in how to register message information specific to each telephone terminal in the exchange system.

(Object of the Invention) The present invention has been made in consideration of the above circumstances, and its purpose is to easily register message information unique to telephone terminals in the exchange system, The purpose of this invention is to provide a message registration method that can enhance the service functions of the Internet.

[Summary of the invention]

This system is designed to perform message information registration processing such as deletion of message information.

At this time, the message information inputted from the data terminal may be displayed on the display and checked before being registered in the memory, or the message information on the telephone terminal may be registered in accordance with a predetermined agreement with the telephone terminal. The registration is controlled on the data terminal side.

〔Effect of the invention〕

Thus, according to the present invention, each telephone terminal is provided with a memory for registering various types of message information, and message information unique to the telephone terminal is registered in this memory using a data terminal connected to the telephone terminal.

For example, it drives the display 25, which has a character display function spanning several lines, to display message information and various control modes, which will be described later, and also to display the software. Various functions assigned to the keys 28 are selectively displayed and controlled in correspondence with a plurality of soft keys 28. Similarly, an LED control circuit 40 connected to the bus 34 drives a plurality of LEDs 27 to perform display control corresponding to the functional state (operating state) of the function key 26. Various kinds of instruction information input via the dial pad 23, function keys 27, and soft keys 28 are

Conversely, data transmitted from the electronic exchange 1 and received via the interface of the transmission system is taken into the CPU 31 from the interface 5 via the bus 34. Also, the message information etc. displayed on the display 25 is CP LJ 3
The message is registered in the message memory 7 provided as a part of the storage area of the RAM 33 under the management control of the RAM 33. This message information is stored in the shift register 4.

Now, the transmission system interface in this telephone terminal 2 is configured as follows. The transmission frame register 51 converts data input from the data terminal 3 etc. via the interface 5, PCM audio data input via the codec/filter circuit 37, and data provided from the shift register 43 into a predetermined frame.・Multiplexed configuration in format. The parity addition circuit 52 adds parity bits to the multiplexed transmission data in this way, and creates transmission data that constitutes one frame of 12 bits, for example, as shown in FIG. In Fig. 7, F is a 1-bit frame synchronization signal, ■ is 8-bit PCM audio data, and D is a 1-bit frame synchronization signal.
is 1 bit communication data, C is 1 bit control data,
P indicates 1-bit parity. The above-mentioned communication data D and control data C are data represented by several bits that are sequentially cut out one bit at a time and inserted into each frame. For example, as shown in FIG. 8, 12-bit control data Go, CI , to C1l form one piece of control information.

Such transmitted data is sent to the NRZ/diphase converter 5.
3, the signal is converted into a diphase signal, and is transmitted to the electronic exchange 1 side via the hybrid circuit 54. Note that a window control circuit 55 connected to the hybrid circuit 54 performs window control on the transmission and reception timing in order to prevent collisions between transmission frames and reception frames on the transmission line connecting the telephone terminal 2 and the electronic exchange 1. It is something.

On the other hand, the electronic exchange 1
The data (reception frame) received from the side is input to the diphase/NRZ converter 56 to undergo data format conversion, and then set in the reception frame register 51. At the same time, the received frame signal is transmitted to the synchronization detection circuit 5.
8 is input. This synchronization detection circuit 58 detects the frame period signal F in the received frame, and detects the synchronization timing of the transmission system from the synchronization detection period and the like. The timing control circuit 59 generates a timing signal that controls the operation of each section described above according to this detected synchronization timing. According to this timing signal, each data of the received frame stored in the received frame register 51 is controlled according to the communication Data D is sent to the data terminal 3 via the interface 5, and PCM audio data (2) is output from the codec/filter circuit 31 via the buffer amplifier 36 to the handset 21, etc. Further, the control data C stored in the reception frame register 57 is sequentially outputted to the shift register 44, and is taken into the CPIJ 31 at the time when one control signal is formed in the shift register 44.

By the telephone terminal 2 having the above configuration, the electronic exchange 1

Transmission and reception are now taking place.

Incidentally, FIG. 6 shows an example of the configuration of the line circuit 11 of the angel exchange ta1 that transmits and receives data to and from the telephone terminal 2. 61 is a hybrid circuit, and 62 is a hybrid circuit for transmitting and receiving data to and from the telephone terminal 2. This is a transmitting/receiving circuit that converts the diphasic signal transmitted and received between the NRZ signal and the NRZ signal.

In other words, this transmitter/receiver circuit 62 has the above-mentioned die phase/receiver circuit 62.
It is configured with an NRZ converter and an NRZ/di-phase converter.

The synchronization detection circuit 63 detects the synchronization timing from data transmitted and received with the telephone terminal 2, and the reception frame memory 64 takes in reception frame data in accordance with this detected synchronization timing. The three registers 65, 66 and 67 provided in parallel separately store the aforementioned communication data D1PCM audio data V and control data C of the received frame data stored in the received frame register 64, respectively. Register 65 above
．． The communication data D and the PCM voice data ■ respectively stored in 66 are selectively sent to the PCM highway inside the electronic exchange 1 via the multiplexer 68, so that they are subjected to the exchange control by exchanging the time slots described above. It has become. Note that the PCM via the multiplexer 68
The timing of sending data to the highway is determined by a counter 69 that counts the internal clock of the exchange 1, and a comparator 70 that detects the own time slot by comparing the counted value of this counter 69 with the unique address assigned to the exchange 1. It's the timing.

The exchange-controlled data is sent to the line circuit 11 via the demultiplexer 71 by exchanging the time slots.
and are selectively stored in registers 72 and 73 according to communication data D=PCM audio data V. Data is also taken in from the PCM highway by detecting the own time slot. Note that the register 74 stores control data for transmission.

Therefore, the CPU 75 provided in the line circuit 11
is for controlling the operation of the line circuit 11 as a terminal interface according to a program stored in the memory 76, for example, and controls its internal operation by inputting the control data C stored in the register 67. There is. Also, among the control data received and input, the data necessary for controlling the exchange 1 is outputted via l1077, and the data necessary for controlling the exchange 1 is
is given to the central control unit.

Further, control data C to be sent from the central control unit to the telephone terminal 2 is inputted via the above-mentioned 11077, and is stored in the register 74. It goes without saying that the operation of the CPU 75 is controlled under instructions from the central control section of the exchange va1.

Transmission frame register 788, each register 72 mentioned above
．． PCM audio data V, communication data D, and control data C for transmission stored in 73 and 74, respectively, are input to create transmission frame data in the frame format described above.

After parity P is added to this transmission frame data via the transmission/reception circuit 62, it is sent to the telephone terminal 2.

Call signals and various data are transmitted between the line circuit 11 of the exchange 1 configured in this manner and the above-mentioned telephone terminal 2 (two-wire bidirectional burst transmission), and the switching operation of the exchange 1 is delayed. Communication between multiple terminals will be exchange controlled.

FIG. 9 schematically shows the form of Bing Bong transmission between the telephone terminal 2 and the exchange 1. In FIG. In this example, switch 1
After transmitting one frame of data having the format shown in FIG. 7 to the telephone terminal 2, the telephone terminal 2
This shows a form in which one frame of data transmitted from the switch 1 to the switch 1 is received. This data transmission is performed repeatedly at a transmission rate of, for example, 64 kbps and at a cycle of 125 μsec. Under these transmission conditions, real-time PCM transmission of the voice (call) signal is realized.

FIG. 10 shows an example of the configuration of the transmitting/receiving circuit 62 used for the above-mentioned Bing Bong transmission (two-wire bidirectional burst transmission), and 81 is a hybrid circuit connected to the two-wire transmission line.
It's trance. This hybrid transformer 81 of 4
A modulator 82 for converting an NRZ signal into a di-phase signal is connected to one of the line-side terminals, and a demodulator 83 for converting a di-phase signal to an NRZ signal is connected to the other, thereby forming the transmitting/receiving circuit 62. .

For example, through such a transmitting/receiving circuit 62,
The NRZ signal as shown in a) is converted into a diphase signal as shown in (b) of the same figure and transmitted, and the received diphase signal as shown in (b) of the same figure is transmitted as shown in (a) of the same figure.
It is converted into an NRZ signal as shown in .

The above is the basic configuration of the system of this embodiment and its communication form.

Now, in a switching system configured in this way,
This system is characterized by one of the switching service functions.
Message memory 7 (RA) stores terminal-specific message information in the message service provided as one
M33), and is transmitted and displayed on the display 25 according to the usage status of the telephone terminal 2 or the usage status of the telephone terminal 2 of the communication partner.

By the way, in the conventional system, various message information is managed on the exchange 1 side exclusively using voice mail equipment.
This is given to the telephone terminal 2 according to its communication status.

That is, in this system, each telephone terminal 2 registers and manages its own message information in the message memory 7, outputs a message according to its communication status, and also transmits message information from the other party through the exchange 1. I am trying to receive it. Of course, it is also possible to receive message information from exchange Ia1.

The CPU 31 registers and manages message information indicating, for example, "absent" or "forwarding destination" in the message memory 7,
When the telephone terminal 2 is called, the calling telephone terminal 2
The above message information is sent out via the exchange 1. This message information is output by selecting one of the plurality of message information registered and managed in the message memory 1 according to the usage status of the telephone terminal 2. In this case, the telephone number or the like of the telephone terminal 2 of the other party who outputted the message information may be registered as one of the message information. Moreover, C P Ll 31 is the switch 1
When message information is received from the other party, or when message information is input from the other party's telephone terminal 2 through the exchange 1 at the time of making a call, the message information is displayed on the display 25. In this case, the received message information is registered in the message memory 7 as necessary.

A message service is executed by transmitting and receiving such message information and displaying the message information.

By the way, the terminal-specific message information used in this way is registered in the message memory 7 in the following manner. Note that this registration of message information includes not only new registration of message information as described above, but also processing of modifying and deleting already registered message information.

FIG. 12 shows the procedure for registering a message on j51 in this system.

When message information registration is instructed by selecting a function using the function keys 26 or soft keys 28 or by dialing a special number using the dial pad 23,
The CPU 31 sets the operating mode of the telephone terminal 2 to "message registration mode". By setting this "message registration mode", the CPU 31 initializes the interface 5 and connects the communication channel between the data terminal 3 and the CP Ll 31 to the interface 5.11035.
, via bus 34. By forming this communication channel, data terminal 3 is set as a message information input terminal for telephone terminal 2.

However, the data terminal 3 serves as a message information input terminal.
Between the CPU 31 and the CPU 31, a control code corresponding to the registration process is used, for example, for new registration...DCl (ASCII code) modification...D C2 (ASCII code) code) Delete・・・・・・・・・DC3(ASCII
code), etc., and is input according to the registration process. The cpU 31 inputs and determines this control information and selects and sets the processing function.

Now, when the new registration mode is set, the CP IJ 31 waits for input of message information. and data terminal 3
Then, message information of a certain number of characters (for example, 24 characters or less) input through the keyboard is edited as a character code string, and this is input into the telephone terminal 2. The CPtJ31 temporarily stores this input message information in the message memory 7, and also stores it in the L C
The signal is supplied to the D tfi control circuit 39 and displayed on the display 25. This display prompts you to confirm the message information you have entered.

If the displayed message information is unsatisfactory, the message information is input repeatedly, and if the displayed message information is satisfactory, a specific control code ( For example a
scii CR) and instruct the end of the confirmation.

At the CP Ll 31, a control code indicating the end of the confirmation is input, and the temporarily stored message information is officially registered (newly registered) in the message memory 7. Registration of this message information is performed by detecting free space in the message memory 1.

Thereafter, the communication channel with the data terminal 3 is closed and the message registration mode is canceled. By canceling this message registration mode, the telephone terminal 2 returns to the normal communication mode.

When the correction mode is instructed, the CPU 31 sequentially selectively reads message information already registered in the message memory 1 and displays it on the display 25. When message information to be corrected is found and specified, the message information is sent to the data terminal 3. The data terminal 3 performs message information correction/editing processing on the parts to be corrected for this message information, and the corrected message information is inputted into the telephone terminal 2 again in the same manner as in the case of new registration. The corrected message information is then temporarily stored in the message memory 7, displayed on the display 25 for confirmation processing, and then officially registered in the message memory 7. Registration of the corrected message information is performed by writing in the area in the message memory 7 where the message information before correction was registered. Thereafter, the communication channel with the data terminal 3 is closed, the message registration mode is canceled, and the process is terminated.

Further, when the deletion mode is set, message information already registered in the message memory 7 is searched in the same manner as in the correction mode described above. When message information to be deleted is retrieved, a control code for deleting the message information is input from the data terminal 3.

Upon receiving this control code, the CPU 31 selectively reads out the message information from the message memory 7, examines the index data of the message information displayed on the display 25, and stores the message information in the corresponding area of the message memory 7 according to this index data. Message information is being deleted. This deletion results in the corresponding message information being deleted.

Thereafter, the communication channel with the data terminal 3 is closed and the process is ended.

Note that a control code (for example, a
SCII DC4), etc. are determined in advance so that when the control code is input in the process of each message registration process described above, the message registration process can be canceled and the normal communication mode can be returned promptly. It is preferable. It is also possible to perform message change processing using the message information deletion function and new registration function.

Also, taking into consideration that there is a possibility that a call will be received to the telephone terminal 2 while the telephone terminal 2 is in the above-mentioned message registration mode, the registration mode is canceled giving priority to the incoming call, or the message information is registered. It would be convenient if a means for selecting whether to give priority to the above is provided. At this time, if you want to give priority to the incoming call, either temporarily save the message information being registered at that time and restart the registration mode when the call from exchange 1 ends, or It is desirable to provide the option of invalidating the previous registration process at the point when the registration process occurs.

In the above-described embodiment, the message information is transferred from the exchange 1 to the telephone terminal 2 as a character code.
For example, an identifier that can identify one of a plurality of messages may be used.

In this case, at least exchange 1 and all telephone terminals 2
It is necessary to know in advance the relationship between each message and the identifier. Therefore, specifically, the relationship between messages and identifiers in the system may be determined as follows.

That is, when message information is input from terminal 2 and transferred to exchange 1, CPU 1 of exchange 1
An identifier is assigned to the message at step 8a. For example, for the message "Kaigichu", the identifier "
For example, an identifier "2" is assigned to the message "Gaishutsuchu". Thereafter, the message and the identifier assigned to the message are transferred from the exchange 1 to each telephone terminal 2 as, for example, control data D. In the telephone terminal 2, for example, E2
Using a rewritable memory such as a PROM, the correspondence between the messages and their identifiers is registered.

Through such identifier assignment processing, messages and their identifiers can be shared between the exchange 1 and each telephone terminal 2.

In this case, it is preferable that the message to which the identifier is assigned is one that is used frequently. Therefore, on the exchange 1 side, it is only necessary to perform statistical processing on the input messages to find frequently used messages, and to allocate identifiers only to these messages. For messages that are frequently used only on the telephone terminal 2, exchange li1! with that terminal 2! It is sufficient to set an identifier that is only allowed between [1] and [1]. Furthermore,
An identifier may be assigned to a fixed message, and a single message may be formed by combining the fixed message specified by this identifier and arbitrary message data. For example, if you combine the fixed message "Kaigichuuu:--Made", which is assigned the identifier "5", with the arbitrary data r0300J and input it as message information r50300J, the resulting message "Kaigichuu 03:00 Made" will be registered. You can also do it.

By using message identifiers in this way, it is possible to simplify message registration, which has great practical advantages.

As described above, according to the present invention, since the data terminal 3 connected to the telephone terminal 2 is used as a means for inputting message information when setting the message registration mode, message information unique to the terminal can be easily registered. Since each telephone terminal 2 is equipped with a message memory 7 to register and manage message information, the system configuration can be greatly simplified and the message service in the exchange system can be enhanced. Many practical effects can be achieved.

Note that the present invention is not limited to the embodiments described above. In the embodiment, the message registration mode is set by an instruction from the function key 26 or the like of the telephone terminal 2, and the opening/closing of the communication channel between the telephone terminal 2 and the data terminal 3 via the interface 5 is instructed. For example, the setting of the message registration mode may be instructed using an ER line, which is a signal line other than the one used for data transmission of the R8232C interface. in this case,
The CP LJ 31 side learns of the communication line connection request of the data terminal 3 according to the level of the ER line detected via the interface 5, and exchanges it based on the difference in control codes from the data terminal 3 (for example, ASCII SEL and 5OH). 1i or a message registration mode setting request.

If all message registration is controlled from the data terminal 3 side in this way, there is no need to install the data terminal 3 near the telephone terminal 2, and flexibility in terminal layout is achieved when constructing a switching system. It becomes possible to increase the

Further, here, the data interface with the data terminal 3 is realized using the interface 5 of the R5232C specification, but it is of course possible to adopt an interface specification such as, for example, X2S. Furthermore, the form of information transmission between the telephone terminal 2 and the electronic exchange 1 is not limited to the above-mentioned bing-bong transmission.

Further, as the data terminal 3, a data terminal such as a TTY that does not have a display function can also be used. In this case, for example, the character/symbol information sequentially inputted from the data terminal may be sequentially displayed as a character/symbol string on the display 25 of the telephone terminal 2, and the message information may be edited and registered on the telephone terminal 2. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.
