Abstract

PURPOSE:To report a call with high urgency to the user by implementing call notice operation when the number of times of reception of the same selective calling signal addressed to a concerned equipment counted for a period when making no call notice operation reaches a prescribed number of times. CONSTITUTION:A control circuit 60 has, e.g. a microcomputer as a main control section and is provided as functions relating to a call notice operation with a 1st call notice control means 61, a 2nd call notice control means 62 and a call notice stop period setting control means 63. Then the 2nd call notice control means 62 counts the number of times of reception of the same selective call signal addressed to its own receiver for a period not implementing call notice operation and controls the receiver to implement the call notice operation when the count number of times reaches a preset number of times. That is, when the same call comes to its own receiver for a prescribed number of times during the call notice stop period by the call notice standby reception function, it is regarded as a call with high urgency, the call notice stop state is released to implement the call notice operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiver having a call notification standby function, and more particularly to a selective call receiver having a function capable of handling emergency calls.

[0002]

2. Description of the Related Art In a selective call system, for example, a selective call signal as shown in FIG. 4 is used. That is, one frame of the selective call signal is time-divided into a plurality of groups (n groups in the figure) as shown in FIG. 4A, and these groups are further divided into a synchronization word and a plurality of groups as shown in FIG. 4B. It is time-divided into a call word (m words in the figure). Also, these calling words are the individual number code (ID code) of the selective calling receiver as shown in FIG.
It consists of a message code and.

When calling the desired selective call receiver, the caller dials the telephone number corresponding to the selective call receiver to call the base station and sends message information to the base station. Then, the base station first generates an ID code previously given to the selective call receiver and a message code obtained by encoding the message information. And 1
The ID code and the message code are respectively inserted into the empty call words of the group to which the selective call receiver belongs, out of a plurality of groups forming the frame, and the frame is transmitted.

On the other hand, FIG. 5 shows an example of the configuration of a selective call receiver used in this type of system. In the figure, a selective call signal transmitted from a base station (not shown) is received by a radio circuit 2 via an antenna 1 and then guided to a mixing circuit 3 where the local oscillation circuit 4
The signal is mixed with the local oscillation signal generated from the frequency converter, frequency-converted to an intermediate frequency or a baseband frequency, demodulated by the demodulation circuit 5 and introduced into the control circuit 6.
The control circuit 6 collates the ID code included in the demodulated selective calling signal with the ID code of the own device stored in advance in the ID code memory (ID-ROM) 7. When a match between the two codes is detected by this collation, it is recognized that a call to the own machine has occurred, and a ringing drive signal is supplied to the drive circuit 8 to drive the speaker 9. For this reason, a ringing tone is generated from the speaker 9, and the owner is notified of the ringing tone.

When the ID code coincidence is detected, the control circuit 6 performs error correction processing on the message code received subsequent to the ID code and then decodes the message code, and the message information reproduced by this decoding. Is supplied to the display drive circuit 10. Therefore, the display device 11 displays the message information. The display 11 is composed of, for example, a liquid crystal display (LCD). Therefore, the user of the selective call receiver can see the LCD 11 at the time of alerting the call,
You can know the message from the caller. The received message code is the message memory (M-
It can be stored in the RAM 12 and read by the operation of the display switch 13 to be displayed again on the LCD 11.

Recently, it has been proposed to provide a selective call receiver of this type with a call notification standby function. The call notification standby function is, for example, that the user sets a call notification stop period by operating a switch, and during this call notification stop period, a call notification operation including a message display operation is performed even if a call addressed to itself is generated. It is a function to prevent it.
If this function is used, for example, even if a call occurs during a time when the user does not have the selective call receiver, the call notification operation can be prevented from being performed. This is very useful because it can prevent the three parties from being known. Further, it is also effective when used in a time zone such as midnight when the call notification operation is not suitable.

[0007]

However, in a selective call receiver having such a call notification standby function, no call notification operation is performed during the call notification suspension period, so a call with a high degree of urgency is required. However, there is a problem in that the user is not notified at all even if the above occurs.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to notify a user of a call with a high degree of urgency even in a state in which a period during which call notification is not performed is set. Thus, the present invention provides a selective call receiver with an improved notification service property.

[0009]

In order to achieve the above object, the present invention receives a selective call signal transmitted from a base station, and performs a call notification operation when the selective call signal is a signal addressed to itself. In the selective call receiver for performing the call notification operation, a call notification period setting means for setting a period for performing or not performing the call notification operation, and a period for not performing the call notification operation set by the call notification period setting means,
In addition to the first call notification control means for controlling so as not to perform the call notification operation even when the selective call signal addressed to the own device is detected, a second call notification control means is provided. Then, the second call notification control means counts the number of times of detection of reception of the same selective call signal addressed to itself in the period in which the above-mentioned call notification operation is not performed, and the number of times reaches the preset predetermined number. In this case, the call notification operation is controlled.

Further, according to the present invention, in the second call notification control means, the number of times of detection of reception of a selective call signal having the same individual number code and the same message information is counted, and the counted number has reached a preset predetermined number. In this case, control is performed so as to perform a call notification operation.

Further, according to the present invention, in the second call notification control means, the number of times the same selective calling signal addressed to the own device is detected is detected within a fixed time from the time when the selective calling signal addressed to the own device is detected. Another feature is that the call notification operation is performed when the number of times reaches a predetermined number.

Further, according to the present invention, when the selective call signal addressed to the own machine is received and detected during the period when the call alert operation is not performed, the information to that effect is stored, and the second call alert control means is provided. , When the above information is read and displayed and the predetermined confirmation operation for the displayed information is not detected, and the number of detections of reception of the same selective call signal addressed to itself reaches the predetermined number of times. In addition, it is also characterized in that it is controlled to perform a call notification operation.

[0013]

As a result, according to the present invention, when the same number of calls to the own machine arrives a predetermined number of times during the call notification suspension period by the call notification standby function, this is regarded as a call with a high degree of urgency. Then, the call notification stopped state is released and the call notification operation is performed. Therefore, even during the call notification suspension period, the user is notified of a call with a high degree of urgency, thereby improving the call performance.

Further, when the selective calling signal having the same individual number code and the same message information arrives a predetermined number of times,
The call notification operation is performed by recognizing this as the arrival of a call with a high degree of urgency. Therefore, the call notification can be performed only when a call with a truly high degree of urgency arrives.

Furthermore, when the same number of calls addressed to the self-apparatus arrives within a predetermined time from the time when the call addressed to the self-apparatus arrives, this is regarded as a call with a high degree of urgency and a call notification operation is performed. I am trying to do it. Therefore, it is possible to clearly notify a call with a high degree of urgency and a call with a low probability with a high probability.

Generally, when a call is made with a high degree of urgency, the caller repeats the same call a plurality of times within a relatively short time until a response is received from the user of the selective call receiver. . Therefore, as described above, it is necessary to monitor the number of times of arrival of selective call signals having the same content or the number of times of selective call signals addressed to the own device, which arrive within a certain time, to make an emergency call to other normal calls. It is extremely effective in distinguishing and recognizing.

Further, according to the present invention, when a call addressed to the own machine arrives during a period in which the call notification operation is not performed, information to that effect is stored and displayed, and the user performs a confirmation operation on this display. When the same call addressed to itself is received a predetermined number of times or more, the call notification operation is performed. Therefore, the call notification operation is performed only when the user has not confirmed a call with a high degree of urgency, whereby unnecessary call notification operation during the call notification suspension period can be avoided as much as possible.

[0018]

1 is a circuit block diagram showing the configuration of a selective call receiver according to an embodiment of the present invention. In the figure, the same parts as those in FIG. 5 are designated by the same reference numerals, and detailed description thereof will be omitted.

The clock circuit 14 has a function of measuring the current time and a timer function of measuring a predetermined time in accordance with a start signal output from the control circuit 60 described later.

By the way, the control circuit 60 has, for example, a microcomputer as a main control unit, and has a first call notification control means 61 as a function related to the call notification operation.
And second call notification control means 62 and call notification stop period setting control means 63.

Of these, the call notification stop period setting control means 63 fetches the time information input by the subsequent switch operation when the call request stop period setting request operation is performed by the user during standby. This is stored as information indicating the call notification suspension period.

The first call notification control means 61 determines whether or not the call notification stop mode is currently set, every time a call addressed to itself is generated, and the call notification stop mode is not set. In this case, the call notification operation is performed as it is, and when the call notification stop mode is set, the call notification operation is controlled not to be performed unless a predetermined condition described later is satisfied.

The second call notification control means 62 determines whether or not the above predetermined condition is satisfied. The predetermined conditions are the following three. The first condition is that the ID code and the message code of the received selective call signal addressed to the own device are the same as the ID code and the message code of the previously received selective call signal addressed to the own device. The second condition is that the selective call signal addressed to the current device is received within a fixed time from the time of receiving the selective call signal addressed to the previous device. The third condition is that the user has not confirmed the previously received call addressed to the own device by the LED 11. And if the above three conditions are satisfied,
Even if the call notification stop mode is set, the call notification operation is performed.

Next, the call notification operation of the selective call receiver configured as described above will be described according to the control procedure of the control circuit 60. In the standby state, the control circuit 60 monitors the arrival of the selective call signal addressed to itself in step 2a as shown in FIG. 2 and monitors the operation of setting the call notification suspension period in step 2b.

In this state, it is assumed that the user operates a plurality of switches in a predetermined combination in order to set the call notification suspension period. Then, the control circuit 60
At step 2c, first, the LCD 11 displays a guidance prompting the user to input the "hour" of the call notification stop start time, and when the user inputs a numerical value in this state, the call notification stop start of the input numerical value is started. It is stored in the RAM in the control circuit 60 as information indicating the "hour" of the time. Similarly, in step 2d, the control circuit 60 causes the LCD 11 to display a guidance prompting the user to input the "minute" of the call notification stop start time, and the numerical value input in this state is the information indicating the "minute" of the call notification stop start time. Is stored in the RAM in the control circuit 60. Then, when the setting of the call notification stop start time is completed, the control circuit 60 next proceeds to step 2e, and this time, the LCD 11 is caused to display a guidance prompting for the input of the call notification stop end time "hour". The numerical value input in this state is stored in the RAM in the control circuit 60 as information indicating "hour" of the call notification stop start time. Similarly, in step 2f, the LCD 11 displays a guidance prompting the user to input the "minute" of the call notification stop end time, and the numerical value input in this state is stored in the control circuit 60 as the information indicating the "minute" of the call notification stop start time. Stored in RAM. Thus, the setting of the call notification stop time is completed.

Now, in this state, it is assumed that the selective call signal addressed to itself is detected. Then, the control circuit 60 executes the call notification control as follows. Figure 3
Is a flowchart showing the control procedure.

That is, the control circuit 60 proceeds to the previous step 3a.
At, it is determined whether the current time of the clock circuit 14 has passed the call notification stop start time set in the RAM.
If it has not passed, the call notification stop mode is released in step 3d. On the other hand, if the current time has passed the call notification stop start time, the process proceeds to step 3b, where the current time is the call notification stop end time. It is determined whether or not it has passed. Then, if the current time has passed the call notification stop end time, the call notification stop mode is released in step 3d, while if the current time has not passed the call notification stop end time, the current time is within the call notification stop period. Then, the procedure shifts to step 3c, where the call notification stop mode is set.

Next, the control circuit 60 proceeds to step 3e, where it is determined whether the call notification stop mode is being set. If the call notification stop mode is not set, the process proceeds to step 3f and the call notification operation is performed as it is. Therefore, the ringing tone is output from the speaker 9 and the received message information is displayed on the LCD 11. Therefore, the user can know the occurrence of the call.

On the other hand, assume that the call notification stop mode has been set. That is, it is assumed that the current time is within the preset call notification suspension period. Then, the control circuit 60
Determines in step 3h whether the ID code and message code inserted in the currently received selective call signal are the same as the ID code and message code of the previously received selective call signal addressed to itself. To do. If they are not the same, that is, if they are the first selective call signals received, the start signal is given to the clock circuit 14 in step 3i to start the timer, and then the process proceeds to step 3g to receive the signal. The ID code and the message code are stored in the message memory 12. That is, in this case, the call notification operation is not performed and only the ID code and the message code are stored.

On the other hand, it is assumed that the ID code and the message code that have just been received are the same as the ID code and the message code that were previously received and stored in the message memory 12. Then, the control circuit 60
In step 3j, it is determined whether or not the timer started at the time when the previous selective call signal addressed to the own device is received has timed out. Then, if it is timed out, it is determined that the selective call signal addressed to the own device this time is not received within a predetermined time from the time of receiving the same selective call signal last time, and the call alert operation is not performed. In step 3g, the ID code and the message code are stored here.

On the other hand, it is assumed that the selective call signal of this time is received before the timer times out, that is, within a fixed time from the time of receiving the same selective call signal of the previous time. In this case, the control circuit 60 proceeds to step 3k, where it determines whether the previous call has been confirmed by the user. Now, suppose that the user switches the display switch 1 between the time when the previous call is received and the time when the current call is received.
It is assumed that 3 is operated to display the previously received message information stored in the message memory 12 on the LCD 11. In this case, the control circuit 60 determines that the user has confirmed the previous call and therefore the call notification is not necessary, and the call notification operation is not performed, and step 3g is performed as it is.
Then, the ID code and the message code are stored here.

On the other hand, when it is determined that the user has not confirmed the previous call, the control circuit 60 proceeds to step 3m and restarts the timer here.
The process moves to step 3f to execute the call notification operation. Therefore, the ringing tone is output from the speaker 9,
Moreover, the received message information is displayed on the LCD 11.
Therefore, the user can know the occurrence of the call even during the call notification suspension period.

As described above, in this embodiment, during the call notification suspension period, the selective call signal having the same ID code and message code as the previous call is received, and this selective call signal is received last time. If it is determined that the reception of the previous selective call signal has not been confirmed by the user within a certain time from the time of receiving the selective call signal, it is during the call notification suspension period, though A call notification operation is performed.

Therefore, according to the present embodiment, even during the call notification suspension period, the user is notified of a call with a high degree of urgency, thereby improving the call performance.

Further, it is determined whether or not the call has a high degree of urgency by determining whether or not the selective call signal having the same ID code and message code as the previous call is received and a predetermined time from the time of receiving the previous call. This is done by determining whether each of the signals has been received. Therefore, a call with a high degree of urgency can be distinguished from other normal calls and accurately recognized with a high probability.

Further, according to the present embodiment, even when a call having the same content as the previously received call is received within a fixed time from the last reception time, the previously received message information is displayed on the LCD 11. In this case, it is determined that the user has confirmed this, and the call notification is not performed. Therefore, unnecessary call notification operation during the call notification suspension period can be avoided as much as possible.

The present invention is not limited to the above embodiment. For example, in the above embodiment, when the message information display operation is performed by the user, this message information is considered to have been confirmed, but when the call occurs, the information to that effect is automatically displayed on the LCD 11. If the user performs a confirmation operation during the display of this information, the call may be regarded as confirmed by the user.

In the above-described embodiment, when the selective call signal having the same content is received twice within a fixed time, this is recognized as a call with a high degree of urgency, but the selective call signal having the same content is constant. If received more than 3 times in time,
This may be recognized as a call with a high degree of urgency. In short, the number of times a call is received when it is recognized as a call with a high degree of urgency can be set arbitrarily.

In the above embodiment, the call notification stop period is set and the call notification stop process is performed during this period. Instead, however, the call notification permission period is set, and the call notification is performed during a period other than this period. You may make it perform a stop process.

Further, in the above embodiment, when the selective call signal having the same content is received twice within the fixed time, this is regarded as a call with a high degree of urgency, and the immediate call notification operation is performed at that time. However, when it is received twice, for example, that effect may be merely displayed on the LCD, and when it is received three times, the call notification operation including the generation of a ringing sound may be performed. That is, you may make it alert | report the call with a high urgency step by step.

Further, as a form of the call notification operation when a call with a high degree of urgency is recognized, the sound volume is reduced or the sound generation cycle is changed in consideration of the fact that the call notification is stopped. For example, the adverse effect may not be exerted.

In addition, the configuration of the selective call receiver, the control procedure and control contents of the call notification control means, the form of the call notification operation (light emission or vibration may be combined in addition to the ringing sound), and the urgency level are selected. The conditions for determining whether or not the call is high can also be modified in various ways without departing from the scope of the present invention.

[0043]

As described above in detail, according to the present invention, a call notification period setting means for setting a period for performing the call notification operation or a period for not performing the call notification operation, and a call notification operation set by the call notification period setting means. In addition to the first call notification control means for controlling so as not to perform the call notification operation even when the selective call signal addressed to the own machine is detected during the non-execution period, the second call notification control means is provided. I have it. Then, the second call notification control means counts the number of times of detection of reception of the same selective call signal addressed to itself in the period in which the above-mentioned call notification operation is not performed, and the number of times reaches the preset predetermined number. In such a case, the call notification operation is controlled.

Therefore, according to the present invention, the user can be informed of a call with a high degree of urgency even in a state in which a period for not making a call notification is set, thereby improving the notification serviceability. A selective call receiver can be provided.
