Manufactured by Toshiba, part number TC35470A
Specified by F. The modem 51 works well in radio communication systems in either full-duplex or half-duplex mode to transfer control signals with subcarrier frequency shift (FSK) modulation.

The modulated output signal from modem 51 is
Connected via a diode 52 to an input of a range limited frequency modulation (FM) transceiver 53 including an integrated RF amplifier / oscillator module 54 having a controllable RF output in the frequency band 46 MHz to 49 MHz. . The output from module 54 is a notch filter with a split output path.

SK) and are overlaid. As mentioned above, the signal passes through the phase locked loop 56 which locks it onto the carrier. By this method, encryption (superimposing digital information on the RF carrier) is done in the phase locked loop 56. The second output path is connected via the transmission / reception switch 57 to the corresponding antenna 59 of the telephone 13 and the antenna 58 in which a radio link is established.

All outgoing messages in the protocol include checksum information. If a data error occurs due to a weak RF condition, this checksum test fails and the error is found. The user will see a temporary message on the screen 16 for 5 seconds "Please try again (Sorr
This error is signaled by "y try again)".

It will be appreciated that the FSK signal described above is received, processed and transmitted from the telephone body 11 even if the telephone body 11 and its telephone 13 are on-hook. This is necessary to identify the caller by the telephone number and / or the caller's name displayed in the screen 16.
Therefore, check the CNID or telephone line (CLID: ca

Subscribers to the CLID, hereinafter referred to as CLID), have the option of accepting or declining a call, if available, because the identity of the caller is first established.

The telephone is received and the telephone body 11
Alternatively, when the communication device 13 goes off-hook, the line transformer (line transformer) 6 is transferred from the terminal 31.
The hook switch 65 forming the audio signal path to the first winding 6 is closed. The output of the line transformer 66 is connected to the circuit 40, from which an analog audio signal is given via the amplifier 41 to drive the speaker 42. The second audio signal output from the circuit 40 is connected to a volume switch 67 from which the audio with the illustrated limiter 69 bridged across to control the signal amplitude via negative feedback. It is connected to the input of amplifier 68. The output from the amplifier 68 is connected to a compander (compressor / expander) 70, from which the output is a potentiometer controller (potentiometer control).
It is input to the diode 52 through 71. The voice signal is connected to the transceiver 53 for transmission to the telephone 13 via the diode 52 in a similar manner to the data transmission described above during the blank interval following the ringing tone.

FIG. 3 is a detailed block diagram of the telephone 13. The modulated RF output signal from the telephone body 11 that generates both voice and data signals is received by the antenna 59 of the telephone 13, the received signal is input to the RF amplifier 76, from which the transceiver 53 of the telephone body 11 is received. Is connected to a transmission / reception switcher (duplexer) 75 which is input to the input of the FM transceiver 77 which is functionally the same. The input of the RF signal to the transceiver 77 is processed by the RF module 78 composed of the first IF / second IF / mixer (audio adjusting device). As the module 78, for example, a module currently available as a product of Motorola Co., Ltd. and specified by the part number MC3362 can be used. It will be appreciated that the module 78 works in concert with the phase locked loop module 79 which acts as a discriminator. As a result, the encrypted data carried by the RF output signal from the telephone body 11 is decrypted (the digital information is extracted from the RF carrier).

The audio output from the module 78 is the DTM.
It may include F, voice, decoded data, and the like. The latter is a logical 1 corresponding to the ID data of the caller regarding the CLASS service to which the telephone user subscribes.
And 0. The other decrypted data includes directory information and a communication protocol. First, the content is confirmed as a response to the protocol by a handshake, the data is transmitted, and then the checksum byte is output. The audio output is divided into two paths, and one path is connected to a low-pass filter 80 that passes an audio signal and blocks a data signal. The audio signal output from the filter 80 is connected to the compander 81. Then, here, a signal in a dynamic range (an operation range in which a signal can be processed without distortion) is restored, and thereafter, a speaker drive amplifier 82 is passed through an attenuation controller (attenuation control) 83.
Is output to. The output from the amplifier 82 is connected to the speaker 84 of the telephone 13 which is reproduced so that an audio signal can be heard.

A manually operated volume control circuit arranged between the contact of the attenuator 83 and the output of the compander 81 is connected to the ground circuit. This volume control circuit
Single pole 3-position allowing selective switching of the switching resistors 87 and 88 from the attenuator 83 to the ground circuit or, in the case of the third setting, an open connection to the ground circuit. It is composed of a switch 86. The resistance value of the resistor 87 or 88 that is switched inside the control circuit is determined by the driver 82.
The input signal to the speaker 84 and, as a result, the speaker 84
The volume at is controlled.

The second audio output path from the module 78 contains both the audio signal transferred from the transceiver 53 in the telephone body 11 and the decoded data.
The MSK modem 95, which corresponds exactly to the modem 51 in the telephone body 11, restores the decrypted input data to it and the microprocessor 3 in the telephone body 11
The pulse train of the reception data input to the microprocessor 96 corresponding to 9 is generated.

Both microprocessors 39 and 96
Function similarly under the same software control. In the microprocessor 96, such software exists in the ROM 97 corresponding to the ROM 45. A comparison of the microprocessors 39 and 96 reveals similarities in the functionally identical circuit configurations of the telephone body 11 and the telephone 13. Therefore, in order to understand the functional aspects of the circuit blocks associated with both microprocessors 39 and 96, the microprocessor 39 shown in FIG. It is sufficient to refer to the description relating to.

However, a clear difference is in the microprocessor 96, in particular in the liquid crystal display (LCD) module 9 including the LCD driver 99 and the LCD screen 16.
On the screen 16 shown in FIG. 3 as 8 is clearly present in the format and output of the received digital data which is connected via the microprocessor 96. The associated LCD output from the microprocessor 96 provides contrast control to the screen 16 by the code keyed in from the dial pad 15.

A further difference is seen in the output of the ring oscillator from the microprocessor 96 applied to the ring amplifier (ring tone amplifier) 106 driving the alert transducer (alerting transducer) 107. The second output from microprocessor 96 is amplifier 1
The ring tone volume control signal is input to the ring tone volume control circuit (ring volume control circuit) 108 that is bridged across the input to 06.

The control of the modules 78, 79 and the modem 95 is influenced by the receive control outputs which control these components via the controller 109.

When the telephone 13 is carried beyond the range of the telephone body 11 and the radio link, the module 78
An indication of being out of range is presented. It consists of an out-of-range signal connected to the input to a noise cut module 110, which is connected across the output of filter 80 to eliminate noisy speech signals. The out-of-range signal is also connected to the input of the microprocessor 96 which, when receiving the signal, results in being unconnected (phone body 11 and telephone 13) under software control. The result is an output signal from the microprocessor 96 to the modem 95 which outputs a drive signal to the transceiver 77 which sequentially transmits to the telephone main body 11 which is in the on-hook state, as shown in the flow chart later.

The circuits related to the speaker 83 and the microphone 115 of the telephone 13 are also included in the speaker 42 and the microphone 46 of the telephone main body 11.
Differences will be noted when compared to. Telephone 13
The reason that the circuit inside is simpler (the circuit inside the telephone body 11) is mainly because there is no unnecessary line transformer 66 and hybrid circuit 40.

The microphone amplifier 116 and its limiter 117 correspond to the volume amplifier 68 and the limiter 69 of the telephone body 11. Although they are functionally the same, the input of the amplifier 116 and the output of the limiter 117 are directly connected to the microphone 115 because of the difference in the communication path between the telephone body 11 and the telephone 13. There is. However, the output of the amplifier 116 and the input of the limiter 117 are connected to the compander 81 corresponding to the compander 70 in the telephone body 11.

When the voice and data signals from the telephone 13 are received by the telephone main body 11, the volume switch 67, the hybrid circuit 40, the transformer 66 and the hook switch 65 are under the control of the microprocessor 39. Cooperate to connect the received voice signal to the telephone line 30. A telephone terminal such as an internal communication system connection (intercom link) between the telephone 13 and the telephone body 11, as well as various features relating to dialing from both the dial pad and the memory and storing data in the memory. Other features associated with 10 will be understood by reference to the description of these features in conjunction with the corresponding flow charts in the drawings.

FIG. 4 is a flowchart showing various steps executed by the telephone terminal 10 after receiving an incoming call which is terminated by the modem 32. As shown, test block 200 determines if there is a matching CLID packet data for Bellcore TR-TSY-00030 and TR-TSY-00031. If no such packet data exists, the microprocessor 33 displays "No information (No information).
n) ”is generated and is output from here to the register 38 along the bus 37. From there, the message is connected at output 50 to modulate the RF carrier for subsequent transmission to handset 13.

On the other hand, if packet data exists,
Exiting at the microprocessor 33, block 203 is then tested for valid CLID data. If valid data is present, a second test is indicated at decision block 204 to see if the caller's ID data has been extracted. If the result is negative, as described above, “No information (No inf
"ormation)" is sent. However, if caller ID data is present, this data is connected to the associated microprocessor 33 in a known manner via the address and data bus 48, as shown in block 205, in a non-volatile memory. NVRA
It is stored in M34.

The second bus 37 is connected to the microprocessor 3
3 is connected to the data input register 38 of the main microprocessor 39 of the telephone body 11 shown in block 206.

Block 207 represents the step of utilizing the transmitted data at the output 50 to modulate (on the RF carrier) at the modem 51, the output of which is the subsequent modulation of the RF carrier and the intercom as described above. Connected to the input of transceiver 53 for transmission to 13.

Block 2 for receiving and demodulating the RF carrier
It is indicated by 08. However, the handset 13 may be out of range of the carrier from the telephone body 11 as determined by decision block 209. Telephone module 13 is module 7
If it is outside the range monitored in 8 (Fig. 3), EEP
Module 98 retrieved from ROM 97 for display
The out-of-range signal is connected to the microprocessor 96 responsive to the out-of-range signal message applied to the. At the same time, a warning sound is emitted. Both conditions are shown in block 210. At this point, the dial pad 1 of the telephone 13
5 is disabled. If the user improves the RF condition within 30 seconds, the out-of-range condition is released, and the telephone terminal 10 is in the state before the out-of-range state, that is, the call is resumed or the functional state continues. .

As indicated by block 211, the timer is subsequently activated and, as indicated by decision block 212, if the weak RF condition persists for more than 30 seconds, the caller 1
3 sends an end message to the telephone body 11 to return to the idle state, that is, the call is terminated or the telephone body 1
If one receives the termination message, the functional state is aborted. The sequence begins at block 213, which sends an end message to the phone body 11, and continues to block 214, which indicates that the end message modulates the carrier and then sends it to the phone body 11. This is followed by block 215, which is the step of receiving the demodulated RF carrier in the phone body 11, followed by a decision block 216 which tests whether the phone body 11 has received an end message. As shown in block 217, the positive response is the caller 1
Set 3 to idle.

The user turns on the telephone 13 before the 30 second timeout (block 212) shown in block 212.
Returning to the carrier range, the demodulated signal of block 208 is microprocessor 96, as shown in block 218, which includes formatting CLID data for display on module 98 according to block 219.
Ends in. At the same time, the microprocessor 96
Generates a ringing signal at block 220, which is applied to the ringing tone at the communicator 13 as shown at block 221. If the telephone is not answered while ringing, as indicated by decision block 222, block 213 issues an end message signal. But,
When answering a call, the sequence of steps illustrated in the flowchart of FIG. 5 follows.

The affirmative decision at block 222 of FIG. 4 ends with an A as input to the flow chart of FIG. 5 where the subsequent steps of the method of the present invention are initiated. When the dedicated call key 20 is pressed by the user, as shown in block 250, the microprocessor 96 which responds based on the instructions stored in the EEPROM 97 is activated. On the other hand, the control command from the microprocessor 96 is transmitted to the telephone main body 11 in the transceiver 77 as indicated by the block 251.
Modulate the F carrier. The carrier wave is received at the telephone body 11 according to block 252, demodulated and subsequently:
According to block 253, the processing is terminated by the microprocessor 39 in the telephone body 11. Based on the instructions stored in EEPROM 47, microprocessor 36 sets hook switch 65 to the off-hook state, as shown in block 254, thereby connecting the first winding of line transformer 66 to terminal 31, As a result, the telephone line 30 is connected.

Simultaneously with the transmission of the RF carrier in block 251, the output of the control signal from the microprocessor 39 enables the audio output from the transceiver 77, as well as the compander 81, speaker drive amplifier 82 and microphone amplifier 116. Is enabled, and the telephone 13 is operated according to blocks 255 and 256.

FIG. 6 is a flowchart showing two features of the present invention embodied in the telephone terminal 10. First, the number entered from the dial pad 15 of the telephone 13 is reserved and dialed on the screen 16 to ensure that the number is correct before actually dialing. Is the ability to display.
The second feature is to store the telephone number in a directory or redial register. Each step of the method shown in FIG. 6 also shows a method in which a telephone number is dialed from the telephone terminal 10.

The input block 275 is the dial pad 1
5 represents the step of making a reservation dial of a telephone number via 5. Dial pad 15 according to block 276
Are scanned by the microprocessor 96, whereby the individual key presses are stored in their input buffers and subsequently formatted according to the instructions stored in the EEPROM 97. This format is
It consists of a contiguous space of telephone numbers, as displayed by module 98 in a format familiar to telephone users. Thus, telephone numbers may be entered from the dial pad as a sequence of consecutive numbers, but the format performed by microprocessor 96 inserts the appropriate spaces between the numbers. In the traditional display format, each space between a series of numbers would be occupied by a dash. Following the formatting as indicated at block 276, the microprocessor 96 is connected to the driver 99 by block 277 and from there to the LC connected to the screen 16.
Generate a D control signal.

The time-out period is arbitrary, but as described above, it is set to 45 seconds in the embodiment of the present invention. If the reserved dial number is displayed for longer than 45 seconds, the display is changed as shown at block 279. When the reserved dial number disappears, re-input from the dial pad 15 is required. At the beginning of the display shown in block 279, block 28
According to 0, the counter starts counting, and following the time interval of 45 seconds, block 281 causes the handset 13 to
It is returned to the idle state and the screen 16 goes blank (no display).

The timeout interval at block 285 represents the time interval at which the user dials the number displayed on screen 16 at block 277. This indicates that the number may be dialed either by pressing the softkey labeled "DIAL" in screen 16 or by pressing the dedicated call key 20 in dial pad 15. It is shown in decision block 282. If the dialing is initiated by either of the blocks 283 and 284, then 45 as described above.
The seconds timeout procedure begins at block 285.

The following test is shown in decision block 286 where it is determined if the handset 13 is out of range from the telephone body 11. If the handset 13 is out of range, the same procedure as illustrated and described in FIG. 4 is followed. If the handset 13 is within range, block 287 indicates that the microprocessor 96 will generate transmit data for output to the modem 95 for modulation and from there to the transceiver 77 for transmission to the telephone body 11. .

As shown in block 288, the received carrier wave is demodulated in the telephone body 11 and subsequently ends in the microprocessor 39 according to block 289. The microprocessor 39 follows the block 291 to put the hook switch 65 into the off-hook state.
Block 290 responds by generating a DTMF signal. As described above, the hybrid circuit 40
Is enabled as shown in block 292,
The DTMF signal is connected via line transformer 66 to terminal 31 and from there to telephone line 30 for connection to a central office, which is represented by block 293.

Simultaneously with the generation of the DTMF signal, the main microprocessor 39 outputs the number string dialed via the data bus 37 to the microprocessor 33 according to the block 294. Here, this sequence of numbers is stored in the redial register as shown in block 295.

Terminal B in FIG. 6 goes to the save routine shown in FIG. Block 30 according to this routine
0 indicates that the reserved dial telephone number displayed on screen 16 by pressing a dedicated save key on cordless telephone 13 can be saved in the directory of telephone numbers. Microprocessor 96 then displays the message "Enter your name now (ENTER) as displayed on screen 16 as shown in block 301.
R NAME NOW) ".

As shown in block 302, the user determines whether the name should be entered. A positive response from the user is that the name corresponding to the number can be entered from dial pad 15 according to block 303, and further according to block 304 the entered name is stored in the number area with its corresponding telephone number. It also means that it is stored in the name area of the directory. Block 304 represents saving the name in one step, which illustrates the steps following receiving the reserved dial number at the main microprocessor 39 and storing the number in the redial register at the microprocessor 33. It will be seen that it is a simplification of some steps shown in FIG. When storing the corresponding name, the storage is done in the non-volatile memory NVRAM 34 in which the directory resides.

FIGS. 8a, b and c are flow charts illustrating the flow in the various directories for storing data including reservation dial, redial and caller item status. These flow charts follow the flow chart description of FIG. 7 which illustrates the steps required to save to a directory. Both names and phone numbers are stored in the directory. As shown in FIG. 7, pressing a dedicated save key adds a new name and telephone number to the directory where the stored names are arranged in alphabetical order by acronym. By pressing a dedicated scroll key on the cordless phone 13, the user can scroll through the items or use dial pad search as a shortcut. The directory can be accessed using only the telephone 13.

The hardware associated with the directory is
It comprises a microprocessor 96 in the telephone 13 and microprocessors 33 and 39 in the telephone body 11. As described above, the data input from the CLID packet is received by the telephone body 11, and the data is formatted by the microprocessor 96,
It is transmitted to the telephone 13 displayed on the screen 16. To save the displayed telephone number and, if available, also the name, press the aforementioned dedicated save key, which initiates the procedure of saving the caller's ID data in non-volatile memory NVRAM 34. Therefore, the user is
With the dial pad 15 and the dedicated key of
The directory feature can be interacted with via a radio link between 1 and the telephone 13.

Information can be stored in the directory from sources numbered below. 1) Reserved dial using the dial pad as described above 2) CLID information received 3) Caller list item 4) Redial list item

The directory feature is accessed by pressing the dedicated directory key or save key as described above. Various items once stored in the directory can be viewed by scrolling up, down, left, and right with dedicated scroll keys.

The maximum number of items in the directory is thirty, but this is not a limited amount as mentioned above and can be varied depending on the size of the memory used. Within the directory, its header format is always the same. This format contains a counter for items, which indicates how many items are in the list. If the directory is empty, the header reads "Directory = No entries (Directory
= No items) "immediately.

The items of the directory are input by the user through the saving sequence as shown in FIG. 7. Both the name and the telephone number are set in the directory, and the items of the name and the telephone number are respectively set. As it is stored, the user can choose to enter an item with only a telephone number. An item with only a telephone number has an area with the name "No name". However, the user can choose to add the name at any time (see Figure 8c). If there is an error, both the name and the telephone number can be corrected by the position indicating cursor that determines the position of the alphanumeric characters, the dial pad 15 and the dedicated delete key on the telephone 13. Alternatively, both the name and the telephone number can be corrected using the softkey below the name "CHANGE" on screen 16, an example of which is shown in block 279 of FIG.

Whenever a directory is not empty, its contents look at the directory header,
It can be accessed by pressing a dial key on the handset 13. By doing so, the shortcut search is started. This shortcut feature allows the user to quickly search the directory by matching the letters on the dialpad keys to the letters in the area of the name of the entry in the directory and then jumping to that entry. In general, the matching algorithm can be any character on the dial pad key, which can be a common character, a special character, or a number, and the matching algorithm looks for a match with the first letter of the name. The items in the directory in which the names are stored are stored in alphabetical order according to the initials of the name string. Items in the directory whose name area is “unnamed” cannot be searched from the dial pad 15. An example of the shortcut search program when the telephone 13 is displaying a directory header or a directory item is shown below.

[0071]   IF key event = Dialpad      Go to Directory item state      Go to first Name item which matches the first character                  on the Dialpad key      IF no match is found          show “<Character> No item entered”      REPEAT      IF next key event = same Dialpad key          Go to first Name item which matches the next                character on the Dialpad key      ELSE IF next key event = different Dialpad key          Go to first Name item which matches the first                character on the new Dialpad key          IF no match is found                Show “<Character> No Item entered”

As a clear example, a user may find "Karen Sloan" in the directory.
Consider the case of trying to find the name. The initials of the name are "K". The letter "K" is the second letter associated with the numeric dial pad key "5".

When the user first presses the "5" key,
"No items have been entered in J (J noite
"Entered)" is displayed. No name starting with "J" is entered in the directory. However, when the user presses the “5” key again, the first is the name of “K”, that is, “Currence loan (K
The items of the directory including "aren Sloan)" are displayed.

The match algorithm looks for all names that begin with the letter "K". If more than one item matches, that is, more than one name has an acronym that matches the search character on the dialpad, the user will see the first matching item that occurs depending on the directory order. Become.

For example, if the user presses the "5" key twice, "Karen Sloan" is displayed. To see other items whose names begin with "K", the user must press the down arrow scroll key. "Karen Sloa
n) ”presses the up arrow scroll key to advance to the preceding alphabetically ordered item.

When the "5" key is pressed three times, the directory "L" item is entered. FIG. 9 is a flowchart of a case where a preferable name search is performed in the case where the ID data of the caller is personalized. When the number received arrives in the CLID packet, the matching algorithm searches the directory to match the number. If a match is found, the name from the directory is displayed and stored in the callers list. If the name has not been received, the area for the name of the item in the directory is displayed, and if received, the name is replaced. It will be appreciated that depending on the number of digits received from the CLID packet, a match will occur at the last 10 digits of the directory entry or at the last 7 letters of the directory entry. With respect to FIG. 9, the preferred name match search is performed as follows.

A) Determine whether the telephone number is dialable or not. If the telephone number is dialable (from the number area of the CLASS dialable directory), proceed to B below. If the phone number is not dialable (from the CLASS CLID area), check the Area Code Strip field. If the area code is stored there, check the first 3 digits of the 10 digit non-dialable telephone number.・ If they match, remove the area code from the non-dialable telephone number and proceed to B below.・ If they do not match, proceed to B with a phone number that cannot be dialed.

B) The number of digits in the digit string from A above is 1
Decide if it is less than 0 or 10 or more. -The following four combinations are possible for the numerical string. 1. Dialable, less than 10 numbers 2. Dialable, 10 numbers or more 3. Not dialable, area code stripped 1
Less than 0 number 4. Not dialable, 10 numbers

In the above cases 1 and 3, the match search is performed with the lower 7 numbers. That is, the bottom seven digits of the digit string are compared with the bottom seven digits of all telephone numbers.

In the cases of 2 and 4 above, the matching search is the lower 10
It is done with individual numbers. That is, the lower 10 digits of the digit string are compared with the lower 10 digits of all telephone numbers.

In any case, if they match, the directory item (name and telephone number) entered by the user is displayed during the incoming call and stored in the caller list as necessary.

The "no name" item in the directory is displayed during the preferred name match search.
It goes without saying that it will not be searched. Therefore, if the name is not stored with the matching number, only the number is shown on the incoming call. If a name is sent in the CLID packet, the preferred name is overwritten in any case by the sent name.
