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 exchange 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. 14(a) to 14(C).

When a telephone terminal calls the telephone terminal C during a call between telephone terminals 0 and 0, if necessary, the telephone terminal's telephone line is temporarily put on hold and the telephone line between telephone terminals 0 and 0 is connected. The telephone terminal 8 interrupts the call between the terminals B and C, and then, as the call between the telephone terminals 0.0 and 0.0 ends, the telephone terminal 8
．． This is to restore the communication line between 0 and 0. Such a busy interrupt function can be effectively used, for example, to communicate urgent requirements.

In addition, the absentee guidance service uses the voice mail device E as shown in FIGS. 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 biggest drawback of the above-mentioned busy interrupt function is that it obstructs communication with the person on the other end of the call, and in order to provide an absentee guidance service using the voice mail device E, the switching system is quite expensive. There was a problem that it would happen. 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 is being considered in which the telephone terminal itself is provided with a display G as shown in FIG. 15 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 greatly improved. However, there remains a problem in how to register message information specific to each telephone terminal in the exchange system.

[Purpose of the invention]

The present invention has been made in consideration of the above circumstances, and its purpose is to easily register message information specific to telephone terminals in an exchange system, and to enhance service functions in the exchange system. The purpose of the present invention is to provide a message registration method that can be used to create messages.

[Summary of the invention]

This system is designed to perform message information registration processing such as new registration of message information in the memory, (1) correction of message information registered in the memo list, and (2) deletion of message information registered in the memory.

At this time, the message information input via the soft keys is displayed on the display and checked, and then registered in the memory.

〔Effect of the invention〕

Thus, according to the present invention, each telephone terminal is provided with a memory for registering various kinds of message information, and the soft keys normally used for controlling various operations of the telephone terminal are used for inputting character and symbol information forming the message information. Since the message information consisting of a string of characters and symbols input through this soft key is registered in the memory, it is easy to control the registration of message information specific to the telephone terminal. Moreover, since the display provided in the telephone terminal can be effectively used to display various message information, editing processing of input message information can be facilitated and various message services can be enriched. Therefore, great effects such as the ability to significantly improve the communication function of the exchange system can be achieved.

Note that the clock generator 16 generates a clock signal that defines the timing of each of these operations.

Each of the circuits described above is connected to the control section 18 via the I10 circuit 17. This control unit 18 includes a CPU 18a, a ROM 18b, and a R

Reference numeral 8d is for connecting a terminal 19 for maintaining and managing the exchange, and for connecting an external storage device for backing up the exchange program, exchange data, etc.

By the way, the telephone terminal 2 has an external shape as shown in FIG. 4, for example, and is configured as shown in FIG. 5.

That is, the telephone terminal 2 has a dial pad 23,
A speaker 24, a display 25 (display 8) consisting of an LCD, a function key 26 for selecting and instructing various functions of the terminal, an LED 27 for displaying the status of the function key 26 (the operating status of the terminal), and an LED 27 for indicating the usage status of the terminal. It is configured with soft keys 28 (soft keys 9) and the like to which various functions are assigned depending on the user's needs. The soft keys 28 are normally used to control various communications and service functions of the telephone terminal, but in a message information registration mode, which will be described later, they are assigned a function for inputting characters and symbols. Further, a data terminal 3 and a tablet 30 for inputting handwritten character information etc. are connected to this telephone terminal 2 via an appropriate interface.
One terminal for the electronic exchange 1 is formed.

As shown in detail in FIG. 5, this telephone terminal 2 includes a CPU 31 as a terminal control section 6, a ROM 32. It is configured to include a main part to which a RAM 33 including a message memory 7 is connected via a bus 34. Under the control of the CPU 31 in accordance with the operating program stored in the ROM 32, the telephone terminal 2 performs data communication with the electronic exchange 1 via the transmission system interface unit (interface 4), and the data terminal It is transmitting and receiving data with the 3rd class. At this time, it operates by storing necessary data in the RAM 33 as appropriate.

The data terminal connection interface 5 connected to the bus 34 via 11035 has an interface specification of, for example, R8232C, and is transmitted from the exchange ta1 side and received by the transmission system interface section of the telephone terminal 2, which will be described later. At the same time, the data inputted from the data terminal 3 is sent to the interface section of the transmission system, and the data is sent to the electronic exchange 1i. Also, some of the data received from the data terminal 3 to the interface 5 may be
(depending on the operating state of the telephone terminal 2) from the 11035 to the CPU 31 via the bus 34;
Data from U 31 is provided to said data terminal 3.

Further, the handset 21 and the speaker 24 are connected via a buffer amplifier 36 to a codec/filter circuit 37 composed of an A/D converter, a D/A converter, a filter, and the like. This codec/filter circuit 37 converts the call signal into PCM voice data, which is then sent to and received from the electronic exchange 1 via the transmission system interface section. The codec/filter circuit 37 is also connected to the bus 34 via the I10 circuit 38, so that necessary data is exchanged with the cpU 31.

The LCD control circuit 39 connected to the bus 34 is connected to the CP
Under the control of U 31, the display on the display 25 is controlled, and for example, the display 25, which has a character display function spanning several lines, is driven to display message information and various control modes, which will be described later. Soft key 28
The display of various functions assigned to the screen is selectively 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 (operation state) of the function key 26. and the dial pad 23, the function key 27,
Various instruction information input via the soft keys 28 are as follows:
11041 to the CPU 31, and the terminal 2
It is used for controlling the operation of the electronic exchange 1 or as control information for the electronic exchange 1.

l10 (interface) also connected to bus 34
42 is an interface for connecting the tablet 30, and handwritten information consisting of, for example, a time series of x-y coordinate data is input from the tablet 30 via this l1042. Also, as described above, c p U
31, the data to be sent to the electronic exchange 1 is taken into the interface 5 via the I1035, and then sent from the interface 5 via the transmission system interface. Conversely, data transmitted from the electronic exchange $1 and received via the interface of the transmission system is taken into the CPU 31 via the interface 5. Also, the message information etc. displayed on the display 25 is
Under the management control of 31, the message is registered in message memory 7 provided as part of the storage area of RAM 33. This message information is input/outputted to the transmission system interface via the shift registers 43 and 44, and is sent/received to/from the electronic exchange 1 as appropriate.

Now, the transmission system interface in this telephone terminal 2 is configured as follows. A transmission frame register 51 receives data input from the data terminal 3 via the interface 5, and the codec/filter circuit 3.
The PCM audio data input through the shift register 43 and the data provided from the shift register 43 are multiplexed into a predetermined frame format. The parity addition circuit 52 adds parity pits 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, D is 1-bit communication data, C is 1-bit control data, and P is 8-bit PCM audio data.
indicates 1-bit parity. The above communication data D
The control data C is one data indicated by several bits that is sequentially cut out one bit at a time and inserted into each frame. For example, as shown in FIG. and 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 the window 1IIl11 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, where the data format is converted, and then set in the reception frame register 57. 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 synchronization 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 for controlling 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 57 is controlled according to the communication timing. Data D is sent to the data terminal 3 via the interface 5, and PCM audio data (2) is sent from the codec filter circuit 37 to the buffer 7.
It is output to the handset 21 etc. via the amplifier 36. 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 CPU 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
Communication signals are exchanged between the telephone terminal 2 and the electronic exchange 1, and necessary data such as 191m data is exchanged between the telephone terminal 2 and the electronic exchange 1.

Incidentally, FIG. 6 shows an example of the configuration of the line circuit 11 of the electronic exchange l111 that transmits and receives data to and from the telephone terminal 2, 61 is a hybrid circuit, and 62 is a telephone terminal connected to the telephone terminal via the hybrid circuit 61. This is a transmitting/receiving circuit that converts a diphasic signal transmitted and received between the two. In other words, this transmitting/receiving circuit 62 is configured to include the aforementioned diphase/NRZ converter and NRZ/diphase 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 D and PCM audio data v1 control data C of the reception frame data stored in the reception frame register 64. , the above register 65
．． 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 in accordance with communication data D and PCM audio data (2). 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
controls 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. Also, among the control data received and input, the data necessary for controlling the exchange 1 is outputted via the I/O 77, and the data necessary for controlling the exchange 1 is outputted to the exchange Va1.
It is given to the central control unit 18 of.

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 1.

The transmission frame register 78 includes each of the registers 72 described above.
．． The transmission frame data in the above-mentioned frame format is created by inputting the PCM audio data (2) for transmission, communication data D1, and control data C stored in 73 and 74, respectively.

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 as described above and the above-mentioned telephone terminal 2 (two-wire bidirectional burst transmission), and multiple data are transmitted by the exchange operation of the exchange Ill. The communication will be controlled by exchange, such as the formation of a communication line between the terminals.

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
7 to the telephone terminal 2, and then receives the one frame of data transmitted from the telephone terminal 2 to the exchange 1. 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.
The message memory 7 (RA
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 exchanges message information from the other party via ill. I am trying to receive it. Of course, it is also possible to receive message information from the exchange 1.

The CP Ll 31 registers and manages message information indicating, for example, "absent" or "forwarding destination" in the message memory 7, and transmits the exchange 1 to the calling telephone terminal 2 when the telephone terminal 2 is called. The above message information is sent through. This message information is output from the message memory 7.
Among the plurality of message information registered and managed in , one is selected according to the usage status of the telephone terminal 2 . In this case, the telephone terminal 2 of the other party that outputs the message information
The telephone number, etc. of the user may be registered as one of the message information. Further, when message information is received from the exchange 1 or when message information is inputted via the exchange 1 to the telephone terminal 2 of the other party at the time of making a call, the C P tJ 31 displays the message information on the display 25. Displaying via. 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 of message registration processing 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 CPL 131 sets the operation mode of the telephone terminal 2 to "message registration mode". By setting this "message registration mode", the CPU 31 changes the functions of the soft key 28 to "new registration", "modification", "delete", etc., respectively. The information is displayed on the display 8 as a registration menu.

When a registration menu selection designation is input via the soft key 28, CP (J 31) determines the input of this control instruction information and selects and sets the processing function.

Now, when the new registration mode is set, the CPIJ 31 assigns the functions of the soft keys 28 to input characters and symbols, and displays the assigned functions of each key 28 on the display 25. The operator learns the characters and symbols assigned to the soft keys 28 according to the information displayed on the display 25, and inputs the necessary characters and symbols by pressing the soft keys 28. In addition, soft key 28
If the character symbol assigned to is not the one required, another character symbol is assigned to the soft key 28 by inputting a request for assignment of another character symbol, and the assignment is displayed on the display 25. Ru. By assigning characters and symbols to the soft keys 28 and inputting instructions for the characters and symbols via the soft keys 28, necessary characters and symbols are input one after another. These input characters and symbols are sequentially displayed on the display 25 as a character and symbol string forming message information.

That is, as shown in FIGS. 13(a) to 13(j), the display 25 is composed of an LCD having three lines and capable of displaying 24 character symbols on each line. The top two lines are a display area for message information, etc., and the bottom line is a function display area for the soft keys 28. In addition, the soft key 28 is
For example, seven are provided along the row below, and the right end is fixedly determined as the next candidate request rNEXTJ. In other words, the six keys on the left side are used as soft keys for selecting and setting functions depending on the usage status of the terminal.

When the message registration mode is set, functions such as F character selection J ``number input'', ``kanji conversion'', and ``end input'' are assigned to the soft keys 28, as shown in FIG. 13(a). After "number input" is instructed, the function of the soft key 28 is changed as shown in FIG.

In this state, the required numbers are entered. Furthermore, rNEXTJ
When the instruction is given, the assignment of numbers to the soft keys 28 is changed.

However, when "character selection" is instructed, the first thing that happens is as shown in Figure 13 (
As shown in C), the information specifying the type of character is, for example, ``UA'' ``AJ rAJ raJ as soft key 2.
Assigned to 8. By selecting and specifying this information, the type of character to be input is instructed to the CP Ll 31. However, following the instructions on the lever, press the soft key 2.
8 is changed as shown in FIG. 13(d), and the function of the r
While character assignments are appropriately changed by operating the NEXTJ key, the character symbols forming the message information are input in order, as shown in FIG. 2(e).

Thereafter, by completing the input of the necessary characters and symbols and instructing, for example, "Kanji conversion", the inputted kana characters and symbols are converted into kanji as shown in FIG. 13(f).
It will be edited as message information. In addition, in this editing process, it is desirable to be able to control the editing process using a cursor, for example, as shown in FIG. 13(l).

Such editing processing can be performed in the same way as the processing of a Japanese word processor by changing the function assignments of the soft keys 28.

The message information input in this manner is given as information consisting of characters and symbols within a certain number of characters (for example, 24 characters), for example. Then, as described above, this message information editing/confirmation processing is performed under the display of a character symbol string on the display 25 and the function selection instruction using the soft keys 25, and the message information to be registered is input and created. Note that if the edited and displayed message information is unsatisfactory, the message information described above is input repeatedly.

After confirming the message information entered, the CP
At U31, the input and edited 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 7. After that, CPLJ31 (telephone terminal 2
) will cancel the message registration mode and return to the normal communication mode.

Further, when the correction mode is instructed, the CPIJ 31 sequentially selectively reads message information already registered in the message memory 7 and displays it on the display 25.
Display at. When the message information to be corrected is found and specified via the soft key 28, the message information is set as data to be processed.

Then use soft key 28 to edit the message information (
Correction) Specify the target location.

This designation of the location to be corrected is performed by moving the cursor in the editing function described above, as shown in FIG. 13(h). Then, in the same manner as in the case of "new registration" described above, input the characters and symbols to be corrected into the correction target part as shown in FIG. Edit and exit.

Thereafter, after receiving confirmation of the corrected message information in the same manner as in the case of new registration, the corrected message information is officially registered in the message memory 7. Registration of the corrected message information is performed by writing in the area in the message memory 1 where the message information before correction was registered. Then, the message registration mode is canceled.

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 above-mentioned modification mode. When the message information to be deleted is retrieved, an instruction to delete the message information is inputted from the soft key 28. Upon receiving this deletion instruction, the CPU 31 examines the index data of the message information displayed on the display 25, and deletes the message information stored in the corresponding area of the message memory 7 according to this index data. There is. This deletion results in the corresponding message information being deleted.

A function for specifying cancellation of the registration mode is set in the soft key 28, and when cancellation is instructed during the process of each message registration process described above, the message registration process is canceled and the normal communication mode is immediately returned. It is preferable to make it possible to return to . 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 first embodiment described above, the message information is transferred from the exchange 1 to the telephone terminal 2 as a character code, but for example, an identifier that can identify one of a plurality of messages may be used.

In this case, at least the relationship between each message and the identifier must be known in advance between the exchange 111 and all telephone terminals 2. Therefore, specifically, do the following:
What is necessary is to define the relationship between messages and identifiers in the system.

That is, when message information is input from terminal 2 and transferred to exchange 1, exchange! 1i1 CP j
An identifier is assigned to the message at l 18a. For example, the identifier "1" is assigned to the message "Kai Gichu", the identifier "2" is assigned to the message "Gai Shutsu Chu", and so on. 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, a rewritable memory such as an E2 PROM is used to register the correspondence between the messages and their identifiers. Through such identifier assignment processing, exchange 1
Messages and their identifiers between the telephone terminal 2 and each telephone terminal 2 can be made common.

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, find messages with high frequency of use as heading 1, and allocate identifiers only to these messages. For messages that are frequently used only in the telephone terminal 2, an identifier that is allowed only between the terminal 2 and the exchange w11 may be set. Furthermore, an identifier may be assigned to a fixed message, and one message may be formed by combining the fixed message specified by this identifier and arbitrary message data. For example, combine arbitrary data r0300J with the fixed message ``Kai Gichu 11211 Made'' assigned the identifier f5j, input it as message information r5030], and register the resulting message ``Kai Gichu 03:00 Made''. You may also do this.

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, the soft key 28 provided on the telephone terminal 2 is assigned the function of inputting characters and symbols in the message registration mode, and the message information is input using the soft key 28. Message information can be easily registered in the telephone terminal 2. Moreover, since each telephone terminal 2 is provided with a message memory 7 and message information unique to each terminal is registered and managed, the system configuration can be greatly simplified. Furthermore, great practical effects can be achieved, such as the ability to enhance message services in the exchange system.

Note that the present invention is not limited to the embodiments described above. In the embodiment, the message registration mode was set by an instruction from the function key 26 or the like of the telephone terminal 2.
The data terminal 3 connected to the telephone terminal 2 may be used to instruct the setting of the message registration mode. In this case, for example, the CPU 31 side knows the connection request for the communication line of the data terminal 3 according to the level of the ER line detected via the interface 5, and receives the control code from the data terminal 3 (for example, ASCII BEL and 5OH )
Based on the difference in the numbers, it may be determined whether the request is a request for data communication via the exchange 1 or a request to set the message registration mode.

Furthermore, the form of information transmission between the telephone terminal 2 and the electronic exchange 1 is not limited to the above-mentioned ping-pong transmission. Furthermore, the method of assigning characters and symbols to the soft keys 28 and the method of editing message information consisting of character and symbol strings input via the soft keys 28 are not particularly limited. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.
