Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio call receiver used as a receiving terminal of a radio call system.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for a radio call system for calling a specific portable receiving terminal by radio using a general subscriber telephone network. Receiving terminals used in this radio calling system, so-called pagers, are roughly classified into the following three types according to their functions.

Tone-on-pager: A pager having only a calling function.

Numerical pager: A pager having a message display function in addition to a calling function. In this case, the messages that can be displayed are limited to those represented by numbers and symbols.

Information pager: A pager having a calling function and a message display function, like the numeric pager. The difference from the Numeric pager is that it can also display messages expressed in English or kana characters.

When a user of such a pager receives a call, he or she needs to identify the caller and respond to the caller.

The caller is identified by occupying a plurality of calling numbers in the tone-on-pager and outputting a different ringing tone for each calling number (however, in reality, the tone having such a configuration is used). There are few online pagers, and in most cases (about 90%), they are operated with a single number, so when using this pager,
It is difficult to identify the sender unless the sender is limited in advance).

On the other hand, in the numeric pager and the information pager, the identification information of the sender included in the message is displayed on the display.

The response to the caller is made by manually dialing the caller's telephone number using a public telephone or the like.

[0010]

However, in the method of manually dialing the caller's telephone number as described above, the telephone number must be confirmed while checking the telephone number in the telephone number book or the display. There was a problem that incorrect connection often occurred due to misreading. In addition, when looking at the telephone number book, there is a problem that it often takes a long time from receiving a call to answering.

Therefore, an object of the present invention is to provide a pager that can respond accurately and quickly when a call is received.

[0012]

In order to achieve the above object, the invention according to claim 1 provides means for outputting number data indicating the telephone number of the other party to be called, and dial tone for this number data. A means for converting into a signal and a means for converting this dial tone signal into an audible sound are provided.

In the invention according to claim 2, the number data output means of claim 1 extracts the number data included in this signal from the received signal and outputs it as the number data of the other party to be called. It is configured as follows.

In the invention according to claim 3, a plurality of number data are registered in advance in the memory or the like by the number data output means of claim 1, and the number data output means is required from the registered number data. According to the configuration, the number data of the other party who should make a call is selected and output.

Further, the invention according to claim 4 is the invention according to claim 1.
The number data output means is configured to output the number data when a predetermined operation key is operated.

[0016]

In the invention according to claim 1, the number data output from the number data output means is converted into a dial tone signal by the dial tone signal converting means. This converted output is converted into an audible sound by the audible sound converting means. Therefore, by bringing this audible sound converting means close to the mouthpiece of a public telephone or the like, it is possible to automatically dial the telephone number of the other party who should make a call.

According to the second aspect of the present invention, the number data of the other party to be called is extracted from the received signal. Therefore, the present invention is premised on that the received signal includes the number data, but when the received signal includes the number data, the number data can be output simultaneously with the calling.

In the invention according to claim 3, the number data of the other party to be called is selected from the number data registered in advance in the memory or the like. Therefore, the present invention, even if the received signal does not include the number data,
The dial can be automated. Further, the present invention enables automation of dialing even when a call is not received.

In the invention according to claim 4, the output of the number data is executed by the user of the pager operating a predetermined operation key. Therefore, according to the present invention, the user of the pager can freely select either one of the automatic dial and the manual dial according to his / her state.

69 is a cursor key for moving the cursor displayed on the display 18.

The operation of the above configuration will be described. In the following description, the case where the present invention is applied to an information pager will be described as a representative.

First, the operation for registering the number data in the RAM 17 will be described.

This registration is performed using the read key 161, the switching key 162, the selection key 163, and the registration key 164.

That is, when the read key 161 is operated by the user of the pager, the signal processor 14 causes the read key 161 to operate.
The character code is read from the programmable ROM 15. This reading is performed one by one each time the read key 161 is operated. In addition, the changeover key 1 determines which code such as a number, a symbol, or a kana character is read.
It is set by 62.

The character code read from the programmable ROM 15 is converted into pattern data and then supplied to the display 18. As a result, the character corresponding to the read code is displayed on the display 18.

When the selection key 163 is operated in this state, the displayed character is displayed as it is, and the newly read character is displayed next to the displayed character. On the other hand, if the selection key 163 is not operated, the newly read character is displayed on the currently displayed character.

By repeating the above processing every time the read key 161 is operated, the identification information of the person who wants to register the telephone number and the telephone number can be input. When this input is completed, the input information is registered in the RAM 17 by operating the registration key 164.

FIG. 3 is a diagram showing an example of the storage structure of the RAM 17.

As shown, the RAM 17 has a plurality of information storage areas A1, A2, .... Each area An (n =
1, 2, ...) stores identification information for one registered person and number data indicating the telephone number. The identification information of the registered person is represented by symbols or kana characters. FIG. 3 shows a representative case in which this is represented by kana characters.

The above-mentioned information storage areas A1 and A
2, ... Are also used to store the message included in the received signal. In this case, this received message is stored in the area next to the last area in which the number data is registered. In the case of FIG. 3, since the final area in which the number data is registered is A3, the received message is stored in A4.

The above is the telephone number registration operation. next,
The operation for automatically dialing the telephone number of the caller when receiving a call will be described.

The calling signal received by the antenna 11 is subjected to frequency conversion processing and detection processing by the radio reception section 12 and is returned to the original signal. The demodulated output is converted into a digital signal by the data reproducing section 13 and then supplied to the signal processing section 14.

FIG. 4 and FIG. 5 are flowcharts separately showing the processing of the signal processing unit 14 at the time of automatic dialing.

As shown in the figure, in the signal processing section 14,
First, it is monitored whether or not a call signal is received (step S11).

When the call signal is received, the call number included in the received signal is compared with the self-identification number stored in the programmable ROM 15 to determine whether or not both match (step). S12). This determines whether the call is for itself.

If it is determined that the call is for itself, that is, if the numbers match, a process for driving the speaker 19 is performed (step S13). As a result, the calling sound is output from the speaker 19.

After that, a message is extracted from the received signal and stored in the RAM 17 (step S).
14). In this case, the message is stored in the area A4 next to the final area A3 in which the telephone number is registered as described above.

Thereafter, the received message is read from the RAM 17 and supplied to the display 18 (step S15). As a result, the received message is displayed on the display 18.

The received message contains the identification information of the sender. Also, depending on the case, number data indicating the telephone number of the caller is included. Therefore, the user of the pager can identify the caller by looking at the received message displayed on the display 18, and determine whether the received message includes the caller's number data. You can

When the display processing of the received message is completed,
It is determined whether the tone generation key 165 has been operated (step S16). If it is determined that it is operated, the process of step S17 is performed, and if it is determined that it is not operated, the process of step S22 is performed.

In step S22, it is determined whether the reference key 168 has been operated. If it is determined that it is operated, the process of step S23 is performed, and if it is determined that it is not operated, the process of step S26 is performed.

In step S26, it is determined whether or not a fixed time has elapsed since the call signal was received. When it is determined that the time has passed, the process of step S19 is performed, and when it is determined that the time has not passed, the process returns to step S16 and the above-described determination process is executed again.

The tone generation key 165 is operated when the received message includes the caller's number data. This is because, in this case, the caller's number data can be obtained from the received message.

On the other hand, the reference key 167 is operated when the caller's number data is not included in the received message. This is because, in this case, the caller's number data cannot be obtained from the received message and must be obtained from the RAM 17.

However, even when the received message includes the sender's number data, this number data may be obtained from the RAM 17 instead of the received message. That is, even in such a case, the reference key 167 may be operated instead of the tone generation key 165.

When the tone generation key 165 is operated, the process of step S17 is executed as described above. In step S17, a process of instructing the pager user to specify the transfer range is performed. As a result, the pager user can select the dial tone generator 2 from the received messages stored in the RAM 17 in step S14.
Processing for designating the range to be transferred to 0 is performed.

This designation is performed on the display 18 by using the range designation key 166 and the cursor key 169. In this case, if the cursor is positioned at the beginning of the transfer range and the range designation key 166 is operated, the beginning of the transfer range is designated, and the cursor is positioned at the end of the transfer range and the range designation key 166 is operated. The last part of the transfer range is specified. By this designation processing, the sender's number data included in the received message can be designated.

When the transfer range is designated in this way, the signal processing unit 14 transfers the designated range to the dial tone generator 20 (step S18). As a result, the caller's number data is supplied to the dial tone generator 20.

The number data supplied to the dial tone generator 20 is converted into a dial tone signal and then supplied to the speaker 19 and converted into an audible sound. Therefore, at this time, if the speaker 19 is brought close to the mouthpiece of a public telephone or the like, the dial tone signal of the caller is input to the general subscriber telephone network through the mouthpiece of the public telephone or the like and is read by the local exchange. It As a result, the caller's telephone number is automatically dialed.

When the transfer of the number data to the dial tone generator 20 is completed, the display on the display 18 is erased (step S19). Then, it is determined whether or not the delete key 168 has been operated (step S20). If it is determined that it has not been operated, the process returns to step S11, and if it is determined that it has been operated, the process of step 21 is executed. In step S21, a process of deleting the received message stored in the RAM 17 in step S14 is performed.

The delete key 168 is operated, for example, when the telephone number of the caller is already registered in the RAM 17, and is not operated when it is not registered. As a result, when the caller's telephone number is already registered, duplicate registration of this telephone number is prevented and the RAM 17 is effectively used. On the other hand, when the telephone number of the caller is not registered, it is not necessary to separately perform the operation for registering the telephone number, so the labor of the registration operation can be saved.

When the process of deleting the received message is completed,
Returning to step S11, when the call signal is received, the above-described processing is executed again.

When it is determined in step S22 that the reference key 167 is operated, as described above, step S2
Process 3 is executed. In this step S23, RA
A process of reading the stored content of M17 and supplying it to the display 18 is performed. This reading is executed only within the range that can be displayed on the display 18.

When this process ends, tone generation key 1
It is determined whether or not 65 has been operated (step S2).
4). If it is determined that the operation has not been performed, a process of updating the read start address is performed (step S25). Then, the process of step S23 is performed again.

Hereinafter, similarly, the processes of steps S23 and S25 are performed until it is determined that the tone generation key 165 has been operated. As a result, the contents stored in the RAM 17 are scroll-displayed on the display 18.

When it is determined that the tone generation key 165 has been operated, the process proceeds to step S17. Thereby, also in this case, it becomes possible to automatically dial the telephone number of the caller. Thereafter, if necessary, the received message is erased, and then the process of step S11 is executed.

If it is determined in step S26 that the fixed time has elapsed, the process proceeds to step S19. As a result, in this case, the process of step S11 is executed after the received message is erased as necessary.

In the above description, the case where the present invention is applied to the information pager has been described. However, the present invention can also be applied to tone-on pagers and numeric pagers.

However, since the tone-only pager does not have a message display function, the user of this pager cannot judge whether or not the received signal includes the caller's number data. Therefore, when the present invention is applied to the tone-on-pager, the dial tone generator 2 extracts the number data from the received signal.
The configuration of supplying 0 has little meaning.

In the above description, the case of receiving a call and responding to the caller has been described. However, how to use the pager is not limited to responding to the caller, but the caller and the callee must be pre-arranged and if a call is received, the pager can be It is also possible to use it to respond.

As described above, the present invention can be applied to the case of responding to a person other than the sender. in this case,
When inserting the number data in the message, if the arrangement is made such that the number data of the person who has agreed in advance is inserted as the number data instead of the number data of the sender, the response destination can be stored without referring to the RAM 17. Number data can be obtained.

According to this embodiment described in detail above, the following effects can be obtained.

(1) First, means (14, 16, 17) for outputting the number data indicating the telephone number of the response destination (sender or person who has agreed beforehand) and means for converting this number data into a dial tone signal. Since (20) and the means (19) for converting the dial tone signal into an audible sound are provided, the telephone number of the answering destination can be automatically dialed. As a result, the telephone number of the response destination can be dialed accurately and quickly.

(2) In addition, since the response destination number data is output by extracting it from the received message, if the received message includes the response destination number data, , The number data can be quickly output without referring to the registered contents of the RAM 17.

(3) Further, as a structure for outputting the number data of the response destination, the number data of the person who can be the response destination is registered in the RAM 17 in advance, and when the call is received, from the registered number data. Since the configuration is provided in which the response destination number data is selected and output, even if the received message does not include the response destination number data, dialing can be automated.

(4) Furthermore, depending on the pager user,
When a predetermined operation key (165, 167) is operated,
Since the number data is output, the user of the pager can freely select either the automatic dial or the manual dial according to his or her situation.

FIG. 6 is a flow chart showing the operation of the second embodiment of the present invention.

In this embodiment, the telephone number of the other party to be called can be automatically dialed even when a call is not received.

That is, in the above embodiment, the case where the telephone number of the other party (in this case, the answering party) to be called can be automatically dialed only when the call is received has been described.

However, as in the previous embodiment, the RAM 17
In the configuration in which the telephone number is registered in advance in, as long as the telephone number of the person who wants to make a call is registered in the RAM 17,
This telephone number can be automatically dialed even when the call is not received.

Therefore, in this embodiment, the number data registered in the RAM 17 can be transferred to the dial tone generator 20 in the processing of the signal processing unit 14 in the previous embodiment except when a call is received. Such a process is added.

FIG. 6 is a flowchart showing the processing after this change. In FIG. 6, the same parts as those in FIGS. 4 and 5 are designated by the same reference numerals and are simplified as appropriate.

In the flowchart of FIG. 6, before the step S11 for judging whether or not the calling signal is received, it is judged at the step S31 whether or not the reference key 167 is operated.
Is provided.

If it is determined in step S31 that the reference key 167 is not operated, the process proceeds to step S11, and if it is determined that it is operated, the process proceeds to step S23. As a result, when the reference key 167 is not operated, the same processing as that in the previous embodiment is executed. To be executed.

With such a configuration, the number data registered in the RAM 17 can be transferred to the dial tone generator 20 as needed, so that the dialing can be automated even when the call is not received. it can.

Although the two embodiments of the present invention have been described in detail above, the present invention is not limited to the above-mentioned embodiments.

(1) For example, in the above embodiment, as the structure for outputting the number data, the first structure for extracting and outputting the received signal and the second structure for selecting and outputting the registered contents of the RAM 17 are output. The case of providing the above configuration has been described.

However, in the present invention, if the dial is automated only when the received signal includes number data, only the first configuration may be provided. Similarly, even when the received signal includes number data, only the second configuration may be provided when selecting from the registered contents of the RAM 17.

(2) Further, in the above embodiment, the case where the pager user outputs the number data when a predetermined operation key is operated has been described.

However, in the present invention, this output operation may be automated. When this automation is performed, in the above-described first configuration, it is automatically determined whether or not the received signal includes number data, and if it is included, this is automatically extracted. There is a need. In order to perform these processes, for example, it is necessary to insert information indicating the presence / absence of number data into the message, and to determine the insertion position of the number data in advance.

Further, in the above-mentioned second structure, it is necessary to automatically judge whether or not the person number data represented by the identification information included in the message is registered in the RAM 19. In order to make this determination, it is necessary to compare the identification information included in the message with the identification information registered in the RAM 19. In order to make this comparison, it is necessary to determine in advance the identification information of the registered person between the caller and the callee.

(3) In addition to this, it is needless to say that the present invention can be variously modified without departing from the scope of the invention.
