Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a radio communication terminal device for mobile communication such as a selective call receiver, and particularly to a base station together with an individual number code. The present invention relates to a device having a function of displaying sent message information.

(Prior Art) Conventionally, a selective call system is known as one of mobile radio systems. The selective call system, for example,
A selective call signal as shown in the figure is used. That is, the selective call signal is time-divided in one frame into a plurality of groups (n groups in the figure) as shown in (a), and these groups are further divided into a synchronization word and a plurality of call words (FIG. M words). These call words are composed of an individual number code (ID code) of the selective call receiver and a message code as shown in (c).

To call the desired selective call receiver, the caller dials the telephone number corresponding to the selective call receiver, calls the base station, and sends message information to the base station. Then, the base station first generates an ID code previously assigned to the selective call receiver and a message code obtained by encoding the message information. Then, the ID code and the message code are respectively inserted into the open call words of the group to which the selective call receiver belongs, among a plurality of groups forming one frame, and transmitted.

FIG. 8 shows an example of the configuration of a selective call receiver. In FIG. 1, a selective call signal transmitted from a base station is received by a radio circuit 2 via an antenna 1, then demodulated by a demodulation circuit 3 and introduced to a control circuit 4.
The control circuit 4 is included in the demodulated selective call signal.
The ID code is collated with the ID code of the own device stored in the individual number code memory (ID-ROM) 5 in advance. When a match between the two codes is detected by this collation, it is recognized that a call to the own device has occurred, and a sound signal is supplied to the speaker 7 via the drive circuit 6. For this reason, the speaker 7
Generates a ringing tone, thereby notifying the holder of the occurrence of the ringing. The ringing tone is stopped by pressing the stop switch 11.

When a match of the ID code is detected, the control circuit 4 performs error correction processing on the message code received following the ID code, decodes the received message code, and further displays the message data obtained by the decoding. Supply to circuit 8. Therefore, message information is displayed on the liquid crystal display (LCD) 9. Therefore, the bearer can know the message from the caller by looking at the LCD 9 at the time of calling notification. The received message code is
The message is transferred to and stored in the message memory (M-RAM) 10. The message code stored in the M-RAM 10 is
The display is read out by pressing the display switch 12
Will be displayed again.

(Problems to be Solved by the Invention) However, in such a conventional selective call receiver, when a call occurs, the received message is unconditionally set to the LC at that time.
The received message stored in the M-RAM 10 is displayed on the LCD 9 by a simple operation of pressing the display switch 12 after receiving the message. For this reason, in some cases, the confidentiality of the received message information may be impaired.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wireless communication terminal device which prevents the received message information from being displayed unconditionally by focusing on the above circumstances, thereby improving the confidentiality of the received message information.

Another object of the present invention is to allow conditional display of received message information for each identification number assigned to the own device, thereby ensuring the confidentiality of important received message information, and for general received messages. An object of the present invention is to provide a wireless communication terminal device that can be easily checked.

[Means for Solving the Problems] To achieve the above object, a wireless communication terminal device according to the present invention is a wireless communication terminal device having a plurality of identification numbers, the identification information transmitted from a base station. Receiving number and message information and determining whether or not the received identification number corresponds to the identification number owned by the receiving apparatus; A storage unit for storing received message information, a display unit for displaying at least the message information, and selectively selecting display conditions for each of a plurality of identification numbers assigned to the own device. Display condition setting means for setting the display condition of the message information stored in the storage means, and a display condition setting means for determining the display condition of the message information stored in the storage means. For message information received together with the identification number the first display condition is set, read from said storage means and displayed on said display means in response to complex specific first display operation, and the second
Display control means for reading out the message information received together with the identification number for which the display condition is set from the storage means in accordance with a single normal second display operation, and displaying the read out information on the display means. doing.

(Operation) According to the present invention, the received message information received together with the identification number for which the first display condition is set by the display condition setting means is displayed by the composite specific first display operation. The received message information received together with the identification number for which the second display condition has been set by the display condition setting means is displayed by a single normal second display operation. Therefore, conditional display of the received message information can be performed for each identification number.

(Embodiment) Next, an embodiment in which the present invention is applied to a selective call receiver will be described. FIG. 1 is a circuit block diagram showing the configuration. 8, the same parts as those in FIG. 8 are denoted by the same reference numerals, and detailed description is omitted.

The selective call receiver of this embodiment has a function switch 13 and a display condition memory (N-RAM) 14 newly. The function switch 13 is used to set message display conditions corresponding to a plurality of identification numbers possessed by the selective call receiver, ie, ID codes, for distinguishing calls. In other words, it is used to specify the display condition setting mode. The display condition memory 14 stores display conditions input in the display condition setting mode in association with ID codes.

By the way, the control circuit 40 has, for example, a microcomputer as a main control unit, and includes a first display operation detection unit 41, a second display operation detection unit 42, a display condition It comprises a judgment means 43 and a display control means 44.

The first display operation detecting means 41 determines whether or not a composite specific display operation has been performed. As the composite specific display operation, for example, an operation of pressing the function switch 13 while pressing the display switch 12 is used. On the other hand, the second display operation detecting means 42 determines whether a single normal display operation has been performed. This single normal display operation is a pressing operation of the display switch 12 as in the past.

The display condition judging means 43, for each received message code, according to the additional code (“1”, “0”) in the received message code and the contents of the display condition stored in the N-RAM 14, It is determined whether the code is to be displayed by the first display operation or to be displayed by the second display operation.

The display control means 44 determines the received message to be displayed by the display condition determination means 43 when a message addressed to itself is received while waiting for a call and when the first and second display operations are performed. The display is controlled according to the result.

Reference numeral 15 denotes a light emitting diode used as one of the call notification means.

Next, the operation of the selective call receiver configured as described above will be described according to the control procedure of the control circuit 40. It is assumed that the selective call receiver has two ID codes A and B, and that the caller can specify display conditions as shown in FIGS. 2 (a) and 2 (b). Description will be made assuming that message information to which the additional code (1, 0) is added is transmitted. In the additional code, “1” corresponds to a first display condition requiring a complex specific first display operation, and “0” can be displayed by a one-shot normal second display operation. This corresponds to the second display condition.

In the call waiting state, as shown in FIG. 3, the control circuit 40 monitors in step 2a whether or not the reception period of each group to which the ID code belongs has been reached. Is confirmed, the process proceeds to reception control. Further, the control circuit 40 sets the display switch in step 2b.
In step 2c, operation monitoring of the function switch 13 is performed, and when it is confirmed that the display switch 12 is pressed, display control of the received message information stored in the M-RAM 10 is performed. Transition. When the operation of the function switch 13 is confirmed, the control circuit 40 shifts to control for setting display conditions.

Now, it is assumed that the owner of the receiver presses the function switch 13 in order to set display conditions in association with the ID codes A and B. Then, the control circuit 40 enters the display condition setting mode, and first monitors the operation of the function switch 13 in step 3a as shown in FIG. And the function switch
If 13 is not pressed, proceed to step 3b where, for example,
The user selects the ID code A and causes the LCD 9 to display the ID code A. In steps 3c and 3d, the operation of the display switch 12 and the stop switch 11 is monitored. If the operation of these switches 11 and 12 is not confirmed, the process returns to step 3a to repeat the above control.

In this state, an ID different from the ID code currently displayed
Assume that the owner presses the display switch 12 to select a code. Then, the control circuit 40 shifts from step 3c to step 3e, selects another ID code B here, and shifts to step 3b. Therefore, the newly selected ID code B is displayed on the LCD 9. If the function switch 13 is pressed again during the above control operation, the operation returns to the call waiting state.

Now, it is assumed that the owner presses the stop switch 11 while a desired ID code (for example, ID code A) is selected. Then, the control circuit 40 determines that the ID code A has been selected and shifts from step 3d to step 3f, where the LCD 9
For example, a guidance message “first display condition?” Is displayed. Here, the first display condition is to use a composite specific first display operation. Then, the control circuit 40 repeatedly monitors the operations of the display switch 12 and the stop switch 11 in steps 3g and 3h, respectively. Then, it is assumed that the owner who confirms the guidance message in this state presses the stop switch 11, for example. Then, the control circuit 40 determines that the first display condition is set for the ID code A, and stores the first display condition in the N-RAM 14 in association with the ID code A.
Then, the process returns to step 3a.

On the other hand, it is assumed that the owner has pressed the display switch 12. Then, the control circuit 40 proceeds to step 3i, selects the second display condition here, and proceeds to step 3f.
For this reason, a guidance message “second display condition?” Is displayed on the LCD 9. Here, the second display condition uses a single normal second operation.
Then, the control circuit 40 repeatedly monitors the operation of the display switch 12 and the stop switch 11 in steps 3g and 3h, respectively, as in the case of the first display condition. If the owner who confirms the guidance message in this state presses, for example, the stop switch 11, the control circuit 40 determines that the second display condition is set for the ID code A, and the first display condition is set. The display conditions are stored in the N-RAM 14 in association with the ID code A. Then, the process returns to step 3a.

The setting of the display condition for the ID code B is performed similarly to the case of the ID code A. When the setting of the display conditions for each of the ID codes A and B is completed, and the holder presses the function switch 13, the control circuit 40 detects this operation in step 3a, and the control circuit 40 detects the operation (step 2). (Fig.).

On the other hand, in the call waiting state, it is assumed that the reception period of each group to which the ID codes A and B belong has come. Then, the control circuit 40 shifts from step 2a in FIG. 2 to the reception control shown in FIGS. 5 (a) and 5 (b). In this reception control, first, a reception ID code and a reception message code are fetched from the demodulation circuit 3 in step 4a, and the own ID codes A and B are read from the ID-ROM 5 in step 4b. Then, in step 4c, both codes are collated, and the received ID is
It is determined whether the code matches each of the own ID codes A and B. If they do not match, it returns to the call waiting state.

Now, for example, the received ID code is your ID
Assume that it matches the code A. Then, the control circuit 40
First, a notification drive signal is output to the drive circuit 6 in step 4d. Therefore, a sound is generated from the speaker 7. The light emitting diode 15 emits light by blinking. Therefore, the owner can be informed of the occurrence of the call by the sound and the blinking light emission. The control circuit 40 also stores the received message code together with the received ID code A in the N-RAM 14 in step 4e.
To memorize.

Next, the control circuit 40 reads out the display condition for the reception ID code A from the N-RAM 14, and determines in step 4g whether the display condition is the first display condition, that is, it is necessary to perform a complex specific display operation. It is determined whether or not there is. In step 4h, it is determined whether the additional code added to the received message code is “1”, that is, whether it is necessary to perform a complex specific display operation. As a result of these determinations, the ID code A
If it is determined that the first display condition is not set and the received message code is not added with the “1” level additional code, the control circuit 40 displays the received message code in a specific display. It is determined that the operation is not so important that the operation is unnecessary, and the process proceeds to step 4i where the received message code is decoded and displayed on the LCD 9. On the other hand, if it is determined that the first display condition is set for the reception ID code, or if it is determined that the “1” level additional code is added to the reception message code, the control is performed. The circuit 40 determines that the received message code must not be displayed unless a specific display operation is performed, and returns to the call waiting state without displaying it.

That is, when a call occurs, a received message is displayed only when a display condition that requires a specific first display operation is not set in both the received ID code and the received message code.

When the reading notification is started as described above and the received message information is further displayed, the control circuit 40
At 4j and step 4k, the operation of the stop switch 11 and the monitoring of whether the first time t1 has elapsed since the start of the call notification are repeatedly monitored, and in this state, the owner presses the stop switch 11, or When the time t1 has elapsed without the stop switch 11 being pressed, the control circuit 40 proceeds to step 41 and stops the notification operation here. In step 4m, it is determined whether or not the received message is being displayed. If the received message is being displayed, the stop switch 11 is operated in step 4n and step 4o, and the first time t2 has elapsed since the start of the call notification. It is monitored repeatedly whether it has been done. In this state, if the owner presses the stop switch 11 or the time t2 elapses without the stop switch 11 being pressed, the control circuit 40
Shifts to step 4p, stops the display here, and returns to the call waiting state. If the received message is not displayed, the process returns to the call waiting state.

By the way, in the call waiting state, in order to read and display the received message stored in the M-RAM 10,
It is assumed that the owner has pressed the display switch 12. Then, as shown in FIG. 6, the control circuit 40 first determines in step 5a whether the first display operation or the second display operation has been performed based on the operation mode of the display switch.
For example, when the display switch 12 is pressed alone once, that is, when a single operation is performed, this is recognized as a second operation. On the other hand, if the function switch 13 is further pressed while the display switch 12 is pressed, that is, if a complex operation is performed, this is recognized as the first display operation.

For example, assume that the owner has performed a single second display operation. Then, the control circuit 40 first proceeds to step 5b
Then, for example, one received message code with the newest reception timing is read from the M-RAM 10 together with the ID code. Next, in step 5c, the display condition corresponding to the read reception ID code is read out from the N-RAM 14, and it is determined whether or not this display condition is the second display condition allowing a single display operation. . If it is the second display condition, step
The process proceeds to 5e, and it is determined whether or not the additional code of the received message code is "0". As a result of this judgment,
If the additional code is "0", the control circuit 40 determines that the received message code can be displayed by a single second display operation, and proceeds to step 5f. After decoding the code, it is displayed on LCD9.

On the other hand, if the first display condition that requires a complex display operation is set for the reception ID code, or if the additional code of the reception message code is “1”, the read reception message is read. It is determined that the code cannot be displayed unless it is a composite first display operation, and the process returns to step 5b to read the next received message code. The routine of steps 5b to 5e is repeated until the second display condition is set for the corresponding reception ID code and the reception message with the additional code "0" of the reception message code is read from the M-RAM 10.

When the display of the received message is started on the LCD 9 as described above, the control circuit 40 monitors the re-operation of the display switch 12 in step 5h, and operates the stop switch 11 and the display in steps 5i and 5j, respectively. It is repeatedly determined whether or not a predetermined time t2 has elapsed from the start. Then, in this state, if the owner presses the stop switch 11 or the time t2 elapses without pressing the stop switch 11, the control circuit 40 proceeds to step 5k, stops the display here, and enters the call waiting state. Return.

If the display switch 12 is pressed again, the control circuit 40 returns from step 5h to step 5a, and determines the operation mode of the display switch as described above.
If the re-operation of the display switch 13 is a single second display operation, steps 5b to 5k described above are performed.
Is repeatedly executed.

That is, when a single normal display operation is performed, for each received message read from the M-RAM 10, the display condition set for the ID code and the additional code added to the received message code are used. It is determined whether or not display by a single normal display operation is possible, and the display is made on the LCD 9 only when it is determined that display is possible. Therefore,
In a single normal display operation, a received message in which the first display condition is set for the ID code and the additional code of the message code is set to “1” cannot be displayed.

On the other hand, it is assumed that the owner further presses the function switch 13 while pressing the display switch 12, for example. Then, the control circuit 40 determines that this operation is a composite specific display operation in step 5a and shifts to step 5q, where the M-RAM 1
Read one received message code from 0. Then, after the read received message code is decoded in step 5f, it is displayed on the LCD 9. The control after the display of the received message is started is the same as the case of the single display operation described above, and is selectively executed in steps 5h to 5k. Thereafter, similarly, every time a complex specific display operation is performed, the routine of steps 5g to 5k is repeatedly executed, whereby the received message codes are read out unconditionally one by one from the M-RAM 10. Displayed on LCD9.

That is, when a composite display operation in which the display switch 12 and the function switch 13 are combined is performed, M-
The received message code stored in the RAM 10 is displayed on the LCD 9 unconditionally.

As described above, according to the present embodiment, the received message code in which the first display condition is set by the ID code is displayed on the LCD 9 unless a composite display operation combining the display switch 12 and the function switch 13 is performed. Cannot be displayed. Therefore, the confidentiality of these received messages is increased.

Further, since display control can be performed by setting display conditions for each message information, it is possible to ensure both confidentiality of important received message information and easy display of general received message information. be able to. Furthermore, according to the present embodiment, display control can be performed by setting display conditions for each ID code.
When code A is used for calling from a company and ID code B is used for calling from a home, respectively,
Message information received from a company can be collectively confidential, and message information received from a home can be displayed by a simple operation without confidentiality.

The present invention is not limited to the above embodiment.
For example, in the above-described embodiment, when a composite first display operation is performed, all received messages stored in the M-RAM 10 can be displayed. Display only received messages, and for other received messages a single secondary message
May be displayed by the display operation of.

Further, when the display condition is set for each ID code, the effective time zone may be set at the same time, and the display condition may be set to be effective only in this effective time zone.

In addition, the means for setting display conditions and the control procedure and control contents of the display control means can be variously modified and implemented without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, the message information received together with the identification number for which the first display condition has been set by the display condition setting means is a composite specific first message. The display is performed by the display operation, and the message information received together with the identification number for which the second display condition is set by the display condition setting means is displayed by a single normal second display operation. As a result, it is possible to provide a wireless communication terminal device which can set display conditions of message information for each identification number, secure confidentiality of important received messages, and easily confirm general received messages. it can.
