PAGER
FIELD OF THE INVENTION The present invention relates to a pager, and in particular to a pager which receives a message of a set phrase tranqritted in code, and displezs the message as the set phrase by display mearis thereof.
DESCRIPTION OF RELATED ART Fig. 1 shows a block diagram of a pager of the conventional type which has a display, and regenerates a set phrase on the display by receiving a set phrase designation character a numeral) in the message data.
Hitherto, with this kind of pager, as shown in Fig. I, modulated signal a received by antenna I is demodulated by radio section 2 and sent out as demodulated signal c from radio section 2 to decoder 3.
Radio section 2 operates to receive intermittently according to a control signal b which comes from decoder 3, for battery saving.
Decoder 3 compares a selective address code included in demodulated signal c with that of the pager read out from the EEPROM (electrically erasable programmable read only memory) 15. When these data coincide, decoder 3 informs microprocessor 4 of detection of the S C C
C
C
CC
*r C _r i 2 assigned selective address code by means of interruption signal d through address bus e and data bus f. Thereafter, decoder 3 corrects errors in the message data which follows the selective address code in demodulated signal c, and then transmits only the message data bits to microprocessor 4 with the assistance of interruption signal d through address bus e and data bus f. An appropriate selective address number is assigned to each pager, and the selecti- address code of each pager is produced by BCH (Bose-Chaudhuri-Hocquenghem) coding for each selective call number.
On receiving detection information of a selective address code from decoder 3, microprocessor 4 stores the detection information in a RAM (not shown) in microprocessor 4 or in RAM 7. Also, microprocessor 4 decides whether data which is successively transmitted after the detection information from decoder 3 is message data or a further selective address code.
When the data from decoder 3 is message data, microprocessor 4 stores the message data in the buffer area of the RAM in microprocessor 4 or of RAM 7. Microprocessor 4 processes this storing operation according to reference clock signal g which is inputted from reference clock 13 through decoder 3.
When the data is a selective address code, the microprocessor 4 stops further reception of the data. In the case t 4 D/474K I a
S
*.aa c 4 't -3of message data, microprocessor 4 starts MPU operation clock 14 and processes the data stored in the above buffer area by using MPU operation clock 14. The data processed by microprocessor 4 is stored as a message (character data) in the message memory area of RAM 7. Further, when microprocessor 4 detects a set phrase designation character, usually a number, included in the data stored in the buffer area, microprocessor 4 converts the set phrase designation character portion to the corresponding set phrase. This set phrase to be converted is stored in advance in EEPROM When the processing of the received message data is finished, microprocessor 4 drives speaker 10, LED (light emitting diode) 11 or vibrator 12 through driver 9 and alerts the carrier of this pager. At the same time, microprocessor 4 displays the LED 11 and vibrator 12 for alerting device is set by recording the device mode in EEPROM 15 through function switch 8. The message stored in the message memory t 15 area of RAM 7 can be displayed again on LCD 5 by function switch 8.
In other words, the set phrase function of the conventional pager acts to display the se'i phrase on LCD 5 retrieved by the set phrase designation number from EEPROM 15, when the set phrase designation [N:\libk00027:BFD ag~-%L rI -4character is received. In this conventional case, since recording of the set phrase into EEPROM 15 is conducted by means of writing terminal 16 of EEPROM an input device other than this pager is additionally needed.
The conventional pager of this kind has no recording function per se for recording the set phrase, so another writing device is needed for recording the set phrase,. Since this writing device is very costly compared with the pager per se and its handling is also a problem, there is a problem that the use of an input device is not popular with users.
Pagers are usually delivered for users after their preferred set phrases have been recorded thereinto. Nhen the user wants to add other set phrases, it is necessary to ask the pager system operator to record the new set phrases. Accordingly, the adding of new set phrases is very inconvenient for the user.
SUMMARY OF THE INVENTION The present invention has been developed to remove the problems of the conventional type pagers described above, and an object is to provide a pager which enables the user to record new set phrases as desired, thereby enabling the user to improve the usability thereof.
D.
r I. itl/ -I -~IIIIR u Therefore, the invention discloses a pager comprising: detection means for detecting a selective address code assigned to said pager; message processing means for processing message data which is received following detection of said selective address code by said detecting means; a message memory which stores a plurality of messages to be processed by said message processing means; a set phrase memory which stores a plurality of set phrases, each of the set phrases being assigned a respective distinguishing number to represent a shortened version of the corresponding set phrase; designation means for designating, for recording, a displayed message and a part of a message as a set phrase, and designating, for display, a stored message or a message and a set phrase together with S 15 its assigned number or a number of set phrases together with respective assigned numbers; and recording means for recording a designated message as a set a *e phrase with an assigned number, storing it into said set phrase memory o and displaying said newly recorded set phrase together with its assigned number in confirmation of recording.

DESCRIPTION OF THE PREFERRED EMBODIMENT Fig. 2 shows a block diagram of an embodiment of the pager of the present invention. This pager is of a similar composition to that of the conventional type shown in Fig. 1, except for a recording function which records a message to be displayed on the display screen 12 into EEPROM 6 using microprocessor 17 which provides with the recording function in addition to the function of microprocessor 4 of conventional pager. The same reference numbers are assigned for blocks having the same functions in both Figs. 1 and 2.
When the recording of a new set phrase is ordered through function switch 8, microprocessor 17 records a portion of the message designated by the function switch 8 stored in the message memory area of RAM 7 into EEPROM 6 as a set phrase. Therefore, ,isers can easily record new set phrases as desired, by transmitting the set phrase by telephone, for example, to this pager.
Fig. 3 is a block diagram of decoder 3 shown in Fig. 2. Bit synchronizing circuit 31 of decoder 3 generates regeneratea clock m from demodulated signal c, and a reference clock signal from oscillation circuit 39. Bit synchronizing circuit 31 outputs regenerated clock m to synchronization control circuit 32, preamble and SC (synchronizing signal) detection circuit (hereinafter 'j l I e i^e !FD/474K i 8 retfered to as "synchronizing signal detection circuit") 33, BCH (Bose-Chaudhuri-Hocquenghem) error correction circuit 34, selective call code detection circuit 35 and baud rate monitor circuit 36.
Synchronization control circuit 32 controls -For battery saving operation which operates intermittent reception of radio waves. Synchronization control circuit 32 is in the battery saving mode while it does not receive any POCSAG (Post Office Code Standardization Advisory Group) 10 signal, and starts continuous reception upon receiving preamble detection signal i from synchronizing (SC) signal 0 detection circuit 33 or baud rate detection signal k from baud rate monitor circuit 36. Synchronization control circuit 32 resumes battery saving operation by receiving 15 synchronizing signal detection signal j sent from preamble and SC signal detection circuit 33 after detection of the C. synchronizing signal, and successively receives signals in accordance with the timing shared to the group to which the 20 pager belongs. Further, when synchronization control circuit 32 receives detection signal o which is generated by the coincidence of the selective address code at selective address code detection circuit 35, radio section 2 keeps receiving the following message d&ta. Furthermore, when synchronization cuntrol circuit 32 starts batterl saving, it outputs battery saving signal h to selective address code -9detection circuit 35 and battery saving control signal b to radio section 2.
Preamble and SC signal detection circuit 33 performs a sampling of demodulated signal c from radio section 2 by means of regenerated clock m from bit synchronizing circuit 31, and generates preamble detection signal i by detecting a preamble signal and outputs preamble signal i to synchronizing control circuit 32. Additionally, when preamble and SC signal detection circuit 33 detects a 10 synchronizing signal in succession to the preambl signal, 4, 4 it generates synchronizing signal detection signal j and outputs it to synchronization control circuit 32.
BCH error correction circuit 34 performs an error correction of demodulated signal c which comes from radio 15 section 2, and outputs message data p to microprocessor 17 by way of MPU interface circuit 37 and data bus f.
Ir *Selective address code detection circuit performs collation of selective address code in4demodulated signal c from radio section 2, in accordance with the timing of battery saving signal h from synchronization control circuit 32. When coincidence of the received selective address code in demodulated signal c and the selective address code of the pager is detected by- ollati,4n selective address code detection circuit 35 outputs coincidence detection signal o to synchronization control 4 4a I- ciicuit 32. Simultaneously, selective address code detection circuit 35 outputs coincidence detection signal o to microprocessor 17 through MPU interface circuit 37 and data bus f. In addition, the selective address code of the pager is set by microprocessor 17 in selective address code detection circuit 35 through MPU interface 37, data bus f and selective address code setting signal q.
Baud rate monitor circuit 36 con \pares regeneration clock m from bit synchronizing circuit 31 with demodulated signal c from radio section 2 and detects whether it is a baud rate of the POCSAG signal to be received. Baud rate detection s;nal k sent from baud rate monitor circuit 36 to synchronization control circuit 32 is used as an activation factor for starting operation for receiving the synchronizing signal in the condition of the battery saving operation state. Signal k is also used, as well as the preamble signal, for canceling battery saving operation.
MPU interface circuit 37 outputs interruption demand signal n to interruption control circuit 38, when receiving message data p from BCH error correction circuit 34 or coincidence detection signal o from selective call code detection circuit Interruption control circuit 38 outputs interruption signal d to microprocessor 4 when it receives interruption demand signal n from MPU interface circuit 37.

Fig. 4 is a flow chart showing message processing operation by microprocessor 17. Message processing operation will be described with reference to Fig. 4.
When interruption signal d,which is generated by the detection of a selective address code is sent from decoder 3 (step 21), microprocessor 17 stores selective address code letection information from decoder 3 in RAM 7 (step 22). Further, when interrupt signal d from decoder 3 is message data (step 23), microprocessor 17 stores the data in a buffer area of RAM 7 (step 24). At this time microprocessor 17 performs the above processing in accordance with the operation clock output of oscillation circuit 39 transferred from reference clock signal g which is inputted from reference clock 13 through decoder 3.
J,
Further, when interruption signal d from decoder 3 does not indicate reception of message data (step 23), that is, interruption signal d from decoder 3 shows detection of the selective address code, at that time microprocessor 17 stops receiving the data and starts MPU operation clock 14 (step 25). Thereafter, microprocessor 17 processes the data i: I: 12 Irr tc i ,r I t e t t t «It t I t

stored in the above buffer area in accordance with MPU operation clock 14 (step 26). Microprocessor 17 stores the processed data as a message (character data) in the message memory area of RAM 7.
Fig. 5 is a time chart along the operation of decoder 3 and microprocessor 17. Case of Fig. 5 shows the timing of battery saving control signal b when no selective address signal of the pager is found in the received POCSAG signals. Case shows the timing of battery saving control signal b when the selective address signal in the received POCSAG signals coincides with the selective address signal of the pager.
Further, case shows the timing of interruption signal d after having received the selective address signal 15 of the pager. Microprocessor 17 reads the message data from decoder 3 with this timing and stores it in the buffer area of RAM 7.
Moreover, case (d)shows the timing of MPU operation clock 14 which generates oscillation. In this oscillation timing chart, the high level portion represents the oscillation by the clock. Microprocessor 17 processes the data stored in the above buffer area with this timing in accordance with MPU operation clock 14 as the operation clock, and stores the processed data as a message (character data) in the message memory area of RAM 7.
13 +Ae, Fig. 6 is a view showing recording area of set phrases in EEPROM 6 shown in Fig. 2. In set phrase recording area 6a of EEPROM 6, set phrases are recorded in each of the numbered areas corresponding to the set phrases.
Namely, in the area corresponding to the set phrase number set phrase "CALL OFFICE" is recorded. Also in the area corresponding to set phrase number set phrase "URGENTLY CONTACT" is recorded. Further, in the area corresponding to set phrase number set phrase "PLEASE PICK UP AT" is recorded. In the area corresponding to set phrase numbers no set phrases are as yet recorded.
Fig. 7 is a view showing two conversion examples of set phrases. Here the conversion examples are shown for the case in which the set phrases shown in Fig. 6 are recorded in the set phrase recording area 6a in EEPROM 6.
As shown in Fig. 7 when a row of characters such that is received, microprocessor 17 refers to set phrase number "01" in set phrase recording area 6a in EEPROM 6, and then displays set phrase "CALL OFFICE" on LCD Also as shown in Fig. 7 when a row of characters such as "--03YOKOHAMA STATION" is received, microprocessor 17 refers to set phrase number "03" in set phrase recording area 6a in EEPROM 6, and then displays set phrase "PLEASE PICK UP AT YOKOHAMA STATION" on LCD 9ii 14 ar I Fig. 8 is a view showing set phrase recording operation according to the embodiment of the present invention, while Fig. 9 is a flow chart showing operation of the embodiment of the present invention. Operation of the embodiment of the present invention will be described with reference to the drawings Fig. 2 through 9.
When the display of LCD 5 is off and the pager is in a waiting mode (step 41), and then SW3 of function switch 8 (hereinbelow referred to as "switch SW3") is depressed, microprocessor 17 reads out the latest message from RAM 7 and displays it on LCD 5 [refer to Fig. 8 (step 42).
Message number 1 is assigned to the top of the latest message. That is, the message "1:YOUR NEXT APPOINTMENT IS AT 9:00" is displayed on LCD 5. When a message is displayed on LCD 5, the pager enters the display waiting mode (step 43).
Whenever switch SW3 is depressed in this mode, successive pictures are displayed on LCD 5 (step Further, received messages are stored in the message memory area of RAM 7 in order of reception, so when there is no successive picture, the next message is displayed on LCD by depressing the switch SW3 refer to Fig. 8 (step 44). That is, the next message "2:PLEASE RETURN TO YOUR OFFICE' is displayed on LCD 5. Further, when SW2 of function switch 8 (hereinbelow referred to as "switch SW2") j Ic St 0 o -V 4 I I I- I 15 is depressed, the preceding message is displayed on LCD (step 46). At that time, if the prescribed time is passed, the display of LCD 5 turns off and the pager returns to the waiting mode (step 41).
When the SW1 of function switch 8 (hereinafter referred to as "switch SW1") is depressed while a message is displayed on LCD 5, the expression (MENU) is shown on LCD [refer to Fig. 8 (step 47). This time the pager enters the menu selection waiting mode (step 48).
10 Here, a cursor on the screen of LCD 5 is moved by :pressing down switch SW3 (step 49), and switch SW2 is depressed when the cursor comes to the position of DELETE, when it changes to the DELETE MODE. Also it switch SW2 is pushed down when the cursor is moved to the PROTECT position, then it becomes the PROTECT MODE. Further, when the cursor is moved to the PROGRAM position and then switch SW2 is depressed, it changes to the PROGRAM MODE [refer to Fig. 8 (step 50). In this case, if switch SWl is pressed down or it passes the prescribed time, then the display of LCD 5 goes off and the pager returns to the waiting mode (step 41).
When the screen shows the PROGRAM MODE, microprocessor 17 reads out the set phrase with the set i phrase number "01" from RAM 7 and displays the set phrase on the second line of LCD 5 together with the set phrase number j r^x: -16 [refer to Fig. 8 That is, on the second line of LCD a set phrase such as "1:CALL OFFICE" is displayed. Now, although the set phrases are stored in set phrase recording area 6a of EEPROM 6, the read rate from EEPROM 6 is slow, so that microprocessor 17 copies the set phrases and set phrase numbers from set phrase recording area 6a of EEPROM 6 into RAM 7 at the time of power input to the pager. When the set phrase and set phrase number are displayed on LCD 5, then the pager enters the waiting mode for recording of a set phrase (step 51).
Whenever switch SW3 is depressed in this state, the set phrase stored in set phrase recording area 6a is displayed on LCD 5 (step 52). When no set phrase is recorded in set phrase recording area 6a, then only the set phrase number is displayed on LCD 5 [refer to Fig. 8 If only this set phrase number is displayed on LCD and then switch SW2 is depressed, a message such as "PLEASE RETURN TO" displayed on the first line of LCD 5 will be recorded in the blank line of set phrase number "04" S 20 [refer to Fig. 8 (step 53). That is, when switch SW2 is depressed, microprocessor 17 reads out the message displayed on the first line of LCD 5 from the message memory area of RAM 7, and writes said message into set phrase recording area 6a and the set phrase recording area of RAM 7. However, when there is a set phrase displayed on the i I l4 i w- ft 17 second line of LCD 5 and then switch SW2 is presqed down, the message displayed on the first line of LCD 5 is superposed on the already recorded portion in set phrase recording area 6a. In this case, if the switch SWl is pressed down or the prescribed time is passed, the display of LCD 5 goes off and the pager returns to the waiting mode (step 41).
In the case where a set phrase such as '"PLEASE RETURN TQ" is recorded by means of the above processing 10 operation, in the position of set phrase number "04" in set phrase recording area 6a and thereafter a row of characters such as "--04YOUR HOME" is received, the microprocessor 17 refers to the set phrase number "04" of set phrase recording area 6a in EEPROM 6 and thus the set phrase such as "PLEASE RETURN TO YOUR HOME" is displayed on LCD 5 [refer to Fig. 8 Fig. 10 is a view showing the format of the POCSAG signal to be used for calling a pager. In Fig, 10 the POCSAG signal comprises a 576 bit preamble signal with a pattern such as a synchronizing signal (SC) for synchronizing a code word, a selective address signal which shows a selective address code, a BCH coded message data of a message to be transmitted and batches.
In Fig. 10 the batch consists of a 32 bit synchronizing siaqal (SC) provided at the top thereof and i 18 code words from CW1 to CW16 divided into eight groups which are intermittently received by each addressed pager of each corresponding group. Further, the code word comprises two types, one an address code word (paging number), the other a message code word (message data).
In Fig. 10 code words are arranged in order from the highest rank bit (MSB Most Significant Bit) to the lowest rank bic (LSB Least Significant Bit), in order an information bit with 21 bits, a check bit with S' 10 bit and a parity bit.
.;This POCSAG signal is described in detail in
I
I: "STANDARD MESSAGE FORMATS FOR DIGITAL RADIO PAGING" and "Post Office Code Standardization Advisory Group (POCSAG), Autumn 1980". POCSAG is a time sharing system, in which 15 battery saving operation is effectuated to reduce the electric curient consumption by the system so that each pager turns its receiving circuit on only within the time of transmitting duration shared for the group to which the pager per se belongs, and turns its receiving circuit off during the time shared by groups other than its own group.
arrang ing Thus, r g by-mcan of the microprocessor 17 in such a way that, when the selective address code is detected by decoder 3 that it is for its own pager, the message signals which follow this selective address code can be processed and stored in the message memory area of RAM 7 Si 19 and the message designated by the function switch 8 among the messages stored in said message memory area is able to recorded in set phrase recording &rea 6a of EEPROM 6 as the set phrase, then the user can record the message which the user transmitted, that is, the user can record the message which he wants to record as a set phrase. Thus it becomes possible to record the set phrase easily, and this function suits the user's requirement and improves of the usability of the system.
While certain representative embodiments have been described for the purpose of illustrating the invention, it will be apparent to those skilled in the trt that various changes and modifications may be made therein without departing from the spirit or scope of the invention.
