Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiver for calling a carrier by various alert methods,
In particular, it relates to the selection of the alert method.

[0002]

2. Description of the Related Art Conventionally, a selective call receiver of this type has a structure as shown in FIG. The signal transmitted from the base station is received by the radio circuit 2 via the antenna 1 of the selective call receiver, and then demodulated by the demodulation circuit 3 into a selective call signal, which is input to the decoder circuit 21 of the matching circuit 4. To be done. Here, the selective call signal demodulated by the demodulation circuit 3 is composed of an individual number code of the selective call receiver, a BCH code including a message code, and a parity bit. The decoder circuit 21 converts the individual number code of the selective call signal as described above into an individual number and the message code into a message, and stores the individual number in the address storage circuit 22 and the message in the message storage circuit 23. The comparison circuit 24 compares the individual number stored in the address storage circuit 22 with the individual number of the selective call receiver written in advance in the storage circuit 5, and if both match, the call to the own device is made. If it is found, the message stored in the message storage circuit 23 is sent to the LCD drive circuit 6 and displayed on the LCD 7. At the same time, the call control circuit 12 activates, for example, the tone generation circuit 14 and sends the special sound generated from the tone generation circuit 14 to the drive circuit 8 to output it from the horn 9.

By the way, when the selective call receiver receives a call to its own device, a special sound or melody is emitted from the horn 9 according to an alerting method previously designated by the position of the switch 15 by the carrier of the selective call receiver. The call control circuit 12 controls whether the call is generated or the vibration is generated by operating the motor 11, thereby informing the wearer that the call is made. That is, as a method of alerting the wearer to the caller by operating the switch 15, the tone generation circuit 1
It is possible to select any one of the special sound generated from No. 4, the melody sound generated from the melody generating circuit 13, and the vibration generated from the motor 11.

However, in such a conventional selective call receiver, the carrier of the receiver can select and switch the alert method as described above, but the caller who makes the call (caller) Was unable to select and specify the alert method of the selective call receiver. Therefore, for example, when the caller wants to make a call to the carrier so as not to be known to others, when he / she wants to make an emergency call, or when he / she wants to make a call to convey other matters, etc. There may be cases where a call is made in the situation.
However, the selective call receiver can only call by the alert method specified by the receiver of the receiver in advance, so even if you want to make a call so that others cannot know it, you can use a special sound or melody. There is a problem that a sound is output and is known to others. Further, since the alert method at the time of calling is set by the carrier as described above, the called party should determine the intention of the caller based on the information which alert method was used to make the call. Therefore, there is a drawback that the intention of the caller cannot be determined unless the message displayed on the LCD 7 is seen.

[0005]

As described above, the alert method for making a call to the carrier of the conventional selective call receiver can be specified only by the switch operation of the carrier having this receiver. , It was not possible to select and specify the alert method from the calling party making a call. For this reason, since the alert method for calling the caller's intention cannot be specified, the called party cannot determine the intention of the caller depending on the type of the calling alert method, and the call displayed on the LCD. The intent cannot be determined without looking at the message sent by the person, and there is a drawback that the burden is imposed on the wearer in a place where it is difficult to see the LCD display, such as in a crowded train. there were.

In view of the above, the present invention eliminates the above-mentioned drawbacks and allows the calling side making a call to select and specify the type of alerting method of the selective call receiver held by the called party, and to make a call. It is an object of the present invention to provide a selective call receiver capable of discriminating a caller's intention depending on the type of alerting method.

[0007]

According to the present invention, there is provided a selective call receiver for making a call when an individual number obtained from a selective call signal including an individual number and a message received from a base station is addressed to itself. Storage means for storing calling method determination information corresponding to the selected call switching message, and a call switching message from the message obtained from the selective calling signal when the individual number obtained from the selective calling signal is addressed to the own machine. And a calling switching message detected by the detecting means, the predetermined calling method is determined based on calling method determination information stored corresponding to the calling switching message that matches the detected calling switching message. And a calling means for making a call suggesting the requirement.

[0008]

In the selective call receiver of the present invention, the storage means stores calling method determination information corresponding to a predetermined call switching message. The detecting means detects the call switching message from the message obtained from the selective call signal when the individual number obtained from the selective call signal is addressed to the own machine.
When the call switching message is detected by the detecting means, the calling means suggests a predetermined message based on the calling method determination information stored corresponding to the call switching message that matches the detected call switching message. Make a call. This allows the calling party on the calling side to select and specify the alerting method of the selective call receiver carried by the called party, and which alerting method was used to call the called party. This allows the called party to know the intent of the calling party without looking at the displayed message.

The collation circuit 4 includes a decoder circuit 21 for decoding the input selective calling signal, an address storage circuit 22 for storing the received individual number, a message storage circuit 23 for storing the received message, the contents of the address storage circuit 22 and the storage circuit 5. The comparison circuit 24 for comparing the stored contents of the above-mentioned memory, the comparison circuit 25 for comparing the call switching message stored in the message storage circuit 23 with the stored contents of the memory circuit 26, and the relationship between the call switching message and the alert method are shown. It has a memory circuit 26 that stores data.

FIG. 3 is an example of table data showing the relationship between the call switching message and the call alert method stored in the storage circuit 26 shown in FIG. For example, it is shown that the call switching message "-0" specifies the alert method by the vibration by the motor 11, and "-1" specifies the alert method by the special sound from the tone generation circuit 14. . It is shown that "-2" to "-9" specify the alert method by the melody generated by the melody generating circuit 13, and the generation of the melody of a different tune can be specified by the call switching message. ing. Further, each of these melodies is set to a content sufficient for associating a predetermined message.

Next, the operation of this embodiment will be described. A radio wave transmitted from a base station (not shown) is received by the wireless circuit 2 via the antenna 1 to become a reception signal, this reception signal is demodulated by the demodulation circuit 3 to become a selective calling signal, and this selective calling signal is further verified. 4 is input to the decoder circuit 21. The decoder circuit 21 decodes the input selective calling signal into individual numbers and messages,
The individual number is stored in the address storage circuit 22 and the message is stored in the message storage circuit 23. The comparison circuit 24 stores the individual number stored in the address storage circuit 22 and the storage circuit 5.
Is compared with the individual number of the selective call receiver stored in advance, and if only the two match, the comparison circuit 25 is activated and the message in the message storage circuit 23 is sent to the LCD drive circuit 6. Send LC
Display on D7.

On the other hand, when the comparison circuit 25 is activated by the comparison circuit 24 as being called, the comparison circuit 25 operates as shown in FIG. First, in step 401, waiting for a call is made, and when there is a call, the process proceeds to step 402, and it is determined whether or not the first character of the message input to the message storage circuit 23 is "-". If not, the process proceeds to step 404, and the call control circuit 1
The alert method designation command is not sent to 2, and the processing of this routine ends. For this reason, the call control circuit 12 calls the carrier using the alert method designated by the switch 15 of the receiver. If the first character of the message is "-" in step 402, step 403
After determining whether the character following the "-" is "0" to "9", the table in the memory circuit 26 shown in FIG. If so, the process proceeds to step 405 to issue a motor drive command, and if it is "1", the process proceeds to step 406 to issue a special sound generation command. If the command is “3”, the process proceeds to step 408 to issue the melody generation command for the second song, and if it is “4”, the process proceeds to step 409 to determine the melody generation command for the third song is “5”. If so, the process proceeds to step 410 to issue the melody generation command for the fourth tune, and if it is "6", the process proceeds to step 411 to issue the melody generation command for the fifth tune to "7".
If so, the process proceeds to step 412 to issue the melody generation command for the sixth song, and if it is "8", the process proceeds to step 413 for the melody generation command for the seventh song, and to "414" if it is "9". Then, the melody generating command for the tune 8 is output to the calling control circuit 12, and this routine is finished.

When a command for designating an alert method is input from the comparison circuit 25, the call control circuit 12 makes a call according to this command. For example, when a motor drive command is input from the comparison circuit 25, the call control circuit 12 drives the drive circuit 10 to rotate the motor 11 to notify the wearer that a call has been made due to vibration. When the special sound generation command is input from the comparison circuit 25, the call control circuit 12 outputs a tone (special sound) generated by activating the tone generation circuit 14 to the drive circuit 8,
This is output from the horn 9 to the outside world to call the wearer. Further, the melody generation command of the first music is the comparison circuit 2
When input from 5, the calling control circuit 12 activates the melody generating circuit 13 to generate the melody of the first music,
This is output from the horn 9 via the drive circuit 8 to call the wearer. Further, if the switch 15 is not operated within a fixed time after the calling, the calling automatically stops after this fixed time (auto reset), and is registered in the address storage circuit 22 and the message storage circuit 23 as a non-call message. To be done. Then, when the switch 15 is operated, the same melody is again generated from the horn 9. Further, when a message is displayed on the LCD 7 by operating the switch 15 at any time, for a message having a call switching message, the melody corresponding to the call switching message is generated from the horn 9.

According to this embodiment, the alert method used by the selective call receiver is designated at the beginning of the message input when the caller calls the desired selective call receiver from the nearest telephone or the like. The alert method of the selective call receiver carried by the callee can be specified simply by inputting the call switching message, and the callee can be called by the alert method as intended by the caller. . Therefore, if you want to send a message "Return" to the called party, if you send a call switching message that causes the song to generate a melody "Return home", the called person can call "Return" just by listening to this song. Can know the intention of the person. Further, when the caller wants to call the called party without being noticed by the people around, the vibration by the motor 11 is specified as the alert method, and the special sound is specified when the emergency call is desired. You can It is possible to eliminate the need to look at the messages displayed on the LCD 7 one by one. Therefore, even if it is troublesome to see the display of the LCD 7 in a crowded place, the caller's intention can be conveyed to the callee. Furthermore, even if the callee cannot confirm the call because the callee, for example, left the selective call receiver unattended and left the call, the call was automatically reset again by a later switch operation. Since the same melody is generated, the message can be surely transmitted. In this case, a large number of different messages can be transmitted even with a selective call receiver that does not have a display for displaying messages. Moreover, the effect of the present embodiment can be realized without changing the hardware or software of the calling side telephone or the like at all. As an alert method corresponding to each call switching message, various methods such as sending a specific message predetermined by voice synthesis or a silent mode in which only a message is displayed on a display device can be considered.

[0016]

As described above, according to the selective call receiver of the present invention, the type of alert method of the selective call receiver possessed by the called party is selected and designated from the calling side making a call. In addition, there is an effect that the intention of the caller can be discriminated depending on the type of the alerting method of calling.
