Description

Paging Receiver and Method of Controlling the Same Background of the Invention Field of the Invention This invention relates to a paging receiver which makes a call report when it receives a paging call through a radio signal including a reception address (page number) allocated to the paging receiver.

Description of the Prior Art When a paging receiver receives a radio signal including a reception address allocated to the receiver, that is, when it receives a paging call to itself, it makes a call report to the person carrying the receiver in the form of a sound from a loudspeaker, flickering of a light emitting element or vibrations of a vibrator. Since a conventional paging receiver normally makes a call report immediately after reception of a paging call to the receiver, the call report is made even if the person carrying the receiver wants to reject all paging calls, such as in the case the person is off duty or must concentrate on a particular job.

Therefore, the user of the receiver is not allowed any time free from potential distraction caused by a paging call.

A paging receiver which has the function of automatically stopping its operation for a time period arbitrarily set by the user has been disclosed in U.S. Patent No.

4,860,005. When a paging receiver of the type mentioned is used, the user may have a time period during which there will be no disturbance caused by a paging call by stopping the operation of the receiver for the desired time period.

However, in this case, all of the paging calls received during the period the operation of the receiver is stopped become unavailable.

Summary of the Invention It is an object of the present invention to provide a paging receiver wherein either a time period during which a call report should be made immediately after the reception of a paging call or a time period during which a call report should be reserved temporarily at the time of reception can be set, and the information relating to the paging call received in the time period during which a call report should be reserved temporarily is stored once in a storage apparatus, and when the time period starts during which a call report should be made immediately, the call report is made according to the stored information.

A time period during which a call report should be made immediately is the time period excepting another time period during which a call report should be reserved temporarily, and the converse is also true. Consequently, setting either time period is equivalent to setting both of the time periods (a pair of the time periods).

Consequently, when the user of the receiver sets either of the time periods, he can pass a certain time interval without paying any attention to paging calls while secure in the knowledge that every paging call which is not reported at the time of reception can be confirmed later; that is, after the time period starts during which a call report should be reported immediately or after the time period ends during which a call report should be reserved temporarily.

It is a further object of the present invention to provide a paging receiver wherein the time period is set corresponding to each of a plurality of reception addresses or, when only one reception address is allocated, the time period is set corresponding to each of predetermined keywords which are conveyed in a radio signal so that different time periods can be set based on the degree of significance of calls according to, for example, the type of calls or the identity of the calling parties.

In order to attain the objects described above, there is provided a paging receiver which makes a call report when it receives a paging call through a radio signal including a reception address allocated to the receiver, said receiver comprising: time period setting means for setting either a time period during which a call report should be made immediately after the paging call is received or another time period during which a call report should be reserved temporarily at the time of reception; timer means for counting the present time; storage means for storing the information relating to the paging call; and control means for controlling the operation of the receiver, wherein the control means makes a call report immediately after the reception of the paging call when neither of the time periods are set, but when either of the time periods is set, if the reception time counted by the timer means is in the time period during which a call report should be made immediately, the control means makes the call report immediately, and if the reception time is in the time period during which a call report should be reserved temporarily, the control means stores the information relating to the paging call into the storage means temporarily and makes the call report when the time period starts during which a call report should be made immediately.

In the paging receiver which achieves the further objects described above, the time period setting means allows setting the time period individually corresponding to each of at least one reception address. In addition, in a paging receiver further comprising means for detecting a keyword included in the radio signal, the time period setting means is capable of setting the time period individually corresponding to each of at least one keyword.

According to another aspect of the present invention, there is provided a method of controlling a paging receiver which makes a call report when it receives a paging call through a radio signal including a reception address allocat ed to the receiver, said method comprising the steps of: detecting the existence of settings for either a time period during which a call report should be made immediately after the paging call is received or another time period during which a call report should be reserved temporarily at the time of reception; making a call report immediately after the reception of the paging call when neither of the time periods is set;; however, when either of the time periods is set, making a call report immediately if the time of reception of the paging call is within the time period during which a call report should be made immediately, and if the time of reception is within the time period during which the call report should be reserved temporarily, storing the information relating to the paging call and making the call report when the time period starts during which the call report should be made immediately.

In the controlling method which achieves the further objects described above, time periods may be set individually corresponding to each of at least one reception address.

In addition, in the method further comprising the step of detecting a keyword included in the radio signal, time periods may be set individually corresponding to each of at least one keyword included in the radio signal.

Brief Description of the Drawings Fig. 1 is a block diagram showing the hardware construction of an embodiment of a paging receiver of the present invention; Figs. 2 through 8 are flow charts illustrating the operation of the paging receiver shown in Fig. 1 in connection with the four embodiments A, B, C and D.

Reception address or keyword Fig. Embodiment to which a corresponding time period is set Fig. 2 & 3 A Second reception address Fig. 4 & 5 B First & Second reception addresses Fig. 6 & 3 C One keyword Fig. 7 & 8 D First and Second keywords Description of the Preferred Embodiments Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a block diagram showing the hardware construction of an embodiment of a paging receiver of the present invention.

The paging receiver of Fig. 1 includes an antenna 1, a radio section 2, a demodulation section 10, a control section 3, ROM 4, RAM 5, a reporting section 6, a display section 11, a slide switch 7, a push switch 8, and a power supply section 9.

The demodulation section 10 demodulates a reception address (page number) and a message included in a radio signal received by the antenna 1 and the radio section 2, and sends them to the control section 3. A keyword is included in the message, transmitted together with the message, and retrieved from the message. The ROM 4 stores a reception address allocated to the receiver and a keyword determined by the user.

The control section 3 refers to the reception address stored in ROM 4 to identify a paging call with the receiver. The control section 3 also identifies the existence of a keyword by referring to ROM 4. The RAM 5 stores the information including a start time and an end time of a time period, a reception time of a paging call, a reception address, a keyword and a message. Reporting section 6 includes a loudspeaker, a vibrator and a light emitting diode for reporting the reception of a paging call by sound, vibration, or emission of light, and display section 11 includes a LCD or a like element for displaying thereon the information relating to a paging call and a time period. The slide switch 7 is used to make power available to the receiver and to select the form of call reporting.

The push switch 8 includes three buttons A, B and C which are used as means for stopping a call report, for reading out call information and for setting a time period. The power supply section 9 supplies power to the components of the receiver. The control section 3 has a built-in timer 31 and controls the function of the components of the receiver.

When a paging call to the receiver is identified, the control section 3 determines whether or not either of the time periods is set, and, when neither of the time periods is set, the control section 3 makes a call report immediately, and when either of the time periods is set, if the time of reception of the call is within a time period during which a call report should be made immediately, a call report is made immediately. If the time of the reception is within a time period during which the call report should be reserved temporarily, control section 3 stores the information relating to the paging call into RAM 5 without making the call report, and when a time period starts during which a call report should be made, the control section 3 processes the call report according to the stored information.Further, in response to the operation of the push switch 8 by the user, the control section 3 permits the call information stored in RAM 5 to be read out and displayed on the display section 11 at any time. Furthermore, in response to the operation of the push switch 8 by the user, the control section 3 permits the setting of a time period for a call report at any time.

Next, the operation of the paging receiver having the hardware construction shown in Fig. 1 will be described with reference to the flow charts in connection with the four embodiments A, B, C and D based on the number of reception addresses allocated to the receiver, the number of keywords determined by the user and in what manner a time period is set corresponding to the reception addresses or keywords.

In the following description, it is assumed that, as the time periods relating to a call report, a time period is set during which a call report should be made immediately, and this time period is hereinafter referred to as the "reporting time period." Any time at which a call report should be made immediately belongs to the "reporting time period" while any other time belongs to the time period during which a call report should be reserved temporarily.

Accordingly, setting a "reporting time period" and setting a time period during which a call report should be reserved temporarily ("report reserving time period") are equivalent time period setting procedures, and naturally, it is possible to alternatively describe the operation of the paging receiver when setting a "report reserving time period." Embodiment A.

1: First and second reception addresses are stored in ROM 4.

2: A reporting time period is set only for the second reception address.

In this instance, when the first reception address is received, or when the second reception address is received at a time within the reporting time period, a call report is made immediately, but when the second reception address is received at a time outside the reporting time period, a call report is not made at that point of time and the call information is stored into RAM 5. When the reporting time period starts, the call report is made automatically. Figs.

2 and 3 illustrate an example of the process executed by the control section 3 in embodiment A above.

Referring first to Fig. 2, when the control section 3 in a waiting condition (step S1) receives a paging call including the reception address stored in ROM 4 (YES at step S2), it determines whether the received address is the first reception address or the second reception address (step S5). When the received address is the first reception address, since no time period is set as yet, the control section 3 activates the reporting section 6 to make a call report (step S6). In this instance, when there is a received message, the message is displayed on the display section 11. The control section 3 then clears the call information thus reported and returns to a waiting condition (step Sol). It is to be noted that, in this instance, any call information in RAM 5 which has not been reported as yet is not cleared. On the other hand, when the received address is the second reception address (step S5), the control section 3 refers to the present time of the timer 31 to determine whether the present time is a time within the reporting time period stored in RAM 5 (step S7), and when the present time is a time within the reporting time period, the control section 3 activates the reporting section 6 to make a call report (step S6). However, when the present time is a time outside the reporting time period, the control section 3 stores into RAM 5 the call information including the information that the call has been received as well as the point of time of the reception and the message included in the received signal (step S8), and then returns into a waiting condition (step S1). In other words, a call report is not made at this point of time.

On the other hand, while the control section 3 is in the waiting condition, it checks whether or not any call information is written in RAM 5 (step S3), and when no call information is written in RAM 5, it remains in the waiting condition. However, when some call information is written in RAM 5, the control section 3 refers to the present time of the timer 31, and when the present time is not included in the reporting time period stored in RAM 5 (NO at step S9), the control section 3 remains in the waiting condition, but when the present time is included within the reporting time period (YES at step S9), the control section 3 activates the reporting section 6 to make the call report and causes the display section 11 to display the message if the message is included in the received signal (step S6).The control section 3 then erases the call information from RAM 5 (step S10) and returns to the waiting condition (step S1).

Further, when button A and button B of the push switch 8 are depressed simultaneously (YES at step S4) while the control section 3 is in the waiting condition S1, the control section 3 enters into a time period setting mode during which a reporting time period can thereafter be set in response to operation of the buttons of the push switch 8, as illustrated in the flow chart of Fig. 3.

Referring to Fig. 3, at steps S13, S16, S19 and S22, it is determined which one or ones of buttons A, B and C of the push switch 8 are depressed by the user.

In this mode, a start time and an end time of a reporting time period stored in RAM 5 at present are displayed on the display section 11 (step Sol). Only the displayed value of the "hour" of the start time flickers (step S12), and each time that button C is depressed (step S13), the displayed value of the "hour" is incremented by one (step S14). In this instance, when the value of the "hour" exceeds 23, it returns to 0. When button B is depressed after the setting of the "hour" has been completed, the procedure advances to the next step (step S13). On the other hand, if button A is depressed, the procedure up to this point is made invalid, and the control sequence returns to the starting step Sll of the time period setting mode.

The processing from steps S15 to S22 proceeds in a similar procedure to effect setting of the "minute" of the start time and the "hour" and the "minute" of the end time, and finally, completion of setting is displayed and the start time and the end time are written into RAM 5 (at step S24), thereby ending the time period setting mode.

It is to be noted that the control section 3 displays the procedure of the setting of the time period on the display section 11 for monitoring by the user, and then writes the values thus set into RAM 5.

Embodiment B.

1: First and second reception addresses are stored in ROM 4.

2: A reporting time period is set corresponding to each of the first and second reception addresses.

In this instance, when the time at which any one of the reception addresses is received belongs to a corresponding one of the reporting time periods, a call report is made immediately. When the time does not belong to the corresponding reporting time period, the call report is not made at that point of time, but the call information is stored into RAM 5 so that, when the reporting time period starts, the call report will be made automatically. Figs. 4 and 5 illustrate an example of the process executed by the control section 3 in embodiment B above.

Referring first to Fig. 4, when the control section 3 in waiting condition S1 receives a paging call including any one of the reception addresses stored in ROM 4 (YES at step S2), it determines whether the received address is the first reception address or the second reception address (step S5). When the received address is the first reception address, the control section 3 refers to the present time of the timer 31 to determine whether it is a time within the reporting time period corresponding to the first reception address stored in RAM 4 (step S21), and if the present time is a time within the time period, the control section 3 activates the reporting section 6 to make a call report (step S6).If it is a time outside the time period, the control section 3 stores into RAM 5 the call information including the information that a call has been received as well as the point of time of the reception, the message, and the kind of the address included in the received signal (step S8), and the control section 3 then returns to a waiting condition (step S1). When the received address is the second reception address, the control section 3 refers to the present time of the timer 31 to determine whether it is a time within the reporting time period corresponding to the second reception address stored in RAM 4 (step S7), and if the present time is a time within the time period, the control section 3 activates the reporting section 6 to make a call report (step S6).If it is a time outside the time period, the control section 3 stores into RAM S the call information including the information that a call has been received as well as the point of time of the reception, the message, and the kind of the address included in the received signal (step S8), and the control section 3 then returns to a waiting condition (step S1).

On the other hand, when the control section 3 is in the waiting condition, it checks whether or not call information is written in RAM 5 (step S3), and if no call information is written in RAM 5, it remains in waiting condition. When some call information is written in RAM 5, the control section 3 determines whether the address included in the call information is the first reception address or the second reception address (step S25).If the address is the first reception address, the control section 3 refers to the present time of the timer 31, and when the present time is not included in the reporting time period corresponding to the first reception address stored in RAM 5 (NO at step S9), the control section 3 remains in waiting condition, but when the present time is included in the time period (YES at step S9), the control section 3 activates the reporting section 6 to make a call report and causes the display section 11 to display the message, if a message is included in the received signal (step S6).The control section 3 then erases the call information from RAM 5 (step S10) and returns to a waiting condition (step Sol). On the other hand, when the received address is the second reception address, the control section 3 refers to the time of the timer 31, and when the present time is not a time within the reporting time period corresponding to the second reception address stored in RAM 5 (NO at step S26), the control section 3 remains in waiting condition, and when the present time is within the time period (YES at step S26), the control section 3 activates the reporting section 6 to make a call report and causes the display section 11 to display the message (step S6) if a message is included in the received signal. The control section 3 then erases the call information from RAM 5 (step Sl0) and returns to a waiting condition (step S1).

Further, when button A and button B of the push switch 8 are depressed simultaneously (YES at step S4) while the control section 3 is in waiting condition S1, the control section 3 enters into a time period setting mode. In this mode, through the procedures illustrated at steps S27 to S29 and S11 to 524 in Fig. 5, the setting of the reporting time period can be performed for each reception address in the order of designation of a reception address, setting of a start "hour", setting of a start "minute", setting of an end "hour" and setting of an end "minute" for the reporting time period. It is to be noted that the control section 3 displays the procedure of the setting of the reporting time period with the relevant reception address on the display section 11 for monitoring by the user, and then writes the values thus set into RAM 5.

Embodiment C.

1: A single reception address is stored in ROM 4.

2: A single keyword is stored as a call report control keyword in ROM 4.

3: A reporting time period is set corresponding to the keyword.

In this instance, when the keyword is not included in a message received or when the keyword is included in a message received at a time within the reporting time period, a call report is made immediately, but when the keyword is included in a message received at a time outside the reporting time period, a call report is not made at this point of time but the call information is stored into RAM 5 so that the call report will be made automatically when the reporting time period starts.

The flow charts of Figs. 6 and 3 illustrate an example of the process executed by the control section 3 in embodiment C above.

Referring first to Fig. 6, when the control section 3 in waiting condition Sl receives a paging call including the reception address stored in ROM 4 (YES at step S2), it determines whether or not the keyword stored in ROM 4 is included in the message then being received (step S31), and when the keyword is not included (step S31), the control section 3 makes a call report (step S6). In this instance, the received message is displayed on the display section 11.

On the other hand, when the keyword is included in the message, the control section 3 refers to the present time of the timer 31 to determine whether or not the present time is within the reporting time period stored in RAM 5 (step S7).

When the present time is within the time period, the control section 3 makes a call report (step S6), but when the present time is outside the time period, the control section 3 stores into RAM 5 the call information including the information that a call has been received as well as the point of time of the reception and the message included in the received signal (step S8), and then returns to the waiting condition (step Sol).

On the other hand, when the control section is in the waiting condition 3, it checks whether or not call information is written in RAM 5 (step S3), and when no call information is written in RAM 5, it remains in waiting condition.

When call information is written in RAM 5, the control section 3 refers to the present time of the timer 31, and when the present time is not included in the reporting time period stored in RAM 5 (NO at step S9), thecontrol section 3 remains in waiting condition, but when the present time is included in the time period (YES at step S9), the control section 3 activates the reporting section 6 to make a call report and causes the display section 11 to display the message (step S6). The control section 3 then erases the call information from RAM 5 (step S10) and then enters back into the waiting condition (step Sl).

Further, when button A and button B of push switch 8 are depressed simultaneously (YES at step S4) while control section 3 is in waiting condition S1, control section 3 enters into a time period setting mode. In this mode, the setting of a reporting time period is performed in the order of setting a start "hour", setting a start "minute", setting an end "hour1, and setting an end "minute" by the procedure illustrated in Fig. 3. It is to be noted that the control section 3 displays the procedure of the setting of the time period on the display section 11 for monitoring by the user, and then writes the values thus set into RAM 5.

Embodiment D.

1: A single reception address is stored in ROM 4.

2: Two of the first and second keywords are stored in ROM 4.

3: A reporting time period is set corresponding to each of the keywords.

In this instance, when neither the first nor second keyword is included in a received message or when one of the keywords is included in a message received at a time within the reporting time period corresponding to the keyword, the call report is made immediately, but when the first or second keyword is included in a message received at a time outside the reporting time period corresponding to the keyword, the call report is not made at that point of time but the call information is stored into RAM 5 so that the call report can be made when the reporting time period starts. The flow charts of Figs. 7 and 8 illustrate an example of the process executed by the control section 3 in embodiment D above.

Referring first to Fig. 7, when the control section 3 in waiting condition S1 receives a call including the reception address stored in ROM 4 (YES at step S2), it determines whether or not the first keyword is included in the message then being received (step S31) and then determines whether or not the second keyword is included in the message (step S41). When neither the first nor second keyword is included, the control section 3 makes a call report (step S6). On the other hand, when the first keyword is included in the message (YES at step S31), the control section 3 refers to the present time of the timer 31 to determine whether or not the present time is within the reporting time period corresponding to the first keyword stored in RAM 5 (step S7).If the present time is within the time period, the control section 3 makes a call report (step S6), but if the present time is outside the time period, the control section 3 stores into RAM 5 the call information including the information that a call has been received as well as the point of time of the reception and the message and the type of keyword included in the received signal (step S8), and then returns to a waiting condition (step S1). When the second keyword is included in the message (YES st step S41), the control section 3 refers to the present time of the timer 31 to determine whether or not the present time is within the reporting time period corresponding to the second keyword stored in RAM 5 (step S42). If the present time is within the time period, the control section 3 makes a call report (step S6), but when the present time is outside the time period, the control section 3 stores into RAM 5 the call information (step S8), and then returns to the waiting condition.

On the other hand, when the control section 3 is in waiting condition S1, it checks whether or not call information is written in RAM 5 (step S3), and when no call information is written in RAM 5, the control section 3 remains in waiting condition. When some call information is written in RAM 5, the control section 3 determines whether the keyword in the call information is the first keyword or the second keyword (step S45).When the keyword is the first keyword, the control section 3 refers to the present time of the timer 31, and when the present time is not included in the reporting time period corresponding to the first keyword stored in RAM 5 (NO at step S9), the control section 3 remains in waiting condition, but when the present time is included in the time period (YES at step S9), the control section 3 activates the reporting section 6 to make a call report and causes the display section 11 to display the message (step S6). The control section 3 then erases the call information from RAM 5 (step S10) and returns to the waiting condition (step S1).On the other hand, when the keyword is the second keyword, the control section 3 refers to the present time of the timer 31, and when the present time is not included in the reporting time period corresponding to the second keyword stored in RAM 5 (NO at step S46), the control section 3 remains in waiting condition, but when the present time is included in the time period (YES at step S46), the control section 3 activates the reporting section 6 to make call report and causes the display section 11 to display the message (step S6). The control section 3 then erases the call information from RAM 5 (step S10) and returns to the waiting condition (step S1).

Further, when button A and button B of the push switch 8 are depressed simultaneously (YES at step S4) while the control section 3 is in waiting condition S1, the control section 3 enters into a time period setting mode. In this mode, through the procedure illustrated at steps S47 to S49 and S11 to S24 in Fig. 8, the setting of the reporting time period can be performed for each key word in the order of designation of a keyword, setting a start "hour", setting a start "minute", setting an end "hour" and setting an end "minute" for the reporting time period. It is to be noted that the control section 3 displays the procedure of setting the reporting time period with relevant key word on the display section 11 for monitoring by the user, and then writes the values thus set into RAM 5.
