Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a radio call receiver implemented by, for example, a pager (pager), and more particularly to a radio call receiver having a function of not notifying a user that a call has been made based on a transmitted message.
[0002]
[Prior art]
A pager as a wireless call receiver is widely used for a caller to call a user carrying the pager from a remote location. Further, in recent years, pagers are not only used for notifying a simple call but also being used in a form for displaying a message transmitted together with a call from a caller.
Since such a call has various purposes and contents, there has been a predetermined keyword in the information included in the received signal as described in JP-A-2-127826. A call receiver that makes it possible to immediately determine whether or not a given call is based on only the call notification is proposed by searching for whether or not the keyword is present and by making the call notification form different depending on whether or not the keyword exists Has been.
[0003]
[Problems to be solved by the invention]
Here, in addition to the case where the caller made the call with the original intention as described above, the purpose and content of the call include the case where the caller mistakenly called the other party, In some cases, a person makes a call with mischief, and when such an abnormal call is made, the pager user is bothered by the call.
In particular, in the case of a call by mischief, a call including a message with an unpleasant content is repeated several times, or a call that does not include any message is repeated many times, such as a silent call. The situation that the troublesomeness of the user becomes considerable will occur.
[0004]
In response to such an abnormal call, in the conventional call receiver described above, it is possible to make the call notification form different, for example, by reducing the volume of the call notification or by calling the LED by emitting light. It is possible. However, in this call receiver, since the call notification operation is not necessarily performed for an abnormal call, the user stops the notification operation or confirms the received message. Therefore, troublesome switch operation has to be performed wastefully. In addition, since a wireless call receiver such as a pager operates with a built-in battery, not only is it bothersome for the user, but also causes a problem that battery power is wasted due to unnecessary notification operations.
Furthermore, in the case of a call by mischief, if a confirmation operation is performed and a message is displayed, the user feels uncomfortable depending on the content of the message, and furthermore, if the number of calls by mischief increases, the call is called It just made me feel uncomfortable.
[0005]
The present invention has been made in view of the above-described conventional circumstances, and an object of the present invention is to provide a wireless call receiver having a function of not notifying a user that a call has been made based on a transmitted message.
More specifically, an object of the present invention is to provide a wireless call receiver in which call notification to a user is prohibited based on the content of a message to be transmitted. It is another object of the present invention to provide a wireless call receiver in which call notification to a user is prohibited based on the presence or absence of a message in a call signal.
[0006]
[Means for Solving the Problems]
The present invention wirelessly receives a call signal including a call number and a message by a receiving means, and compares the received call number with a call number assigned to itself stored in the call number storage means. And is applied to a radio call receiver for notifying that a call has been made by the notifying means when the received call number matches the own call number.
[0007]
When the keyword specified by the user is received from the keyword input means, the keyword is stored in the keyword storage means, and when the call signal is received by the receiving means, the keyword search means is included in the call signal. Whether the keyword stored in the keyword storage means is included in the received message, and if the keyword stored in the keyword storage means is included in the received message, the call signal is received. A radio paging receiver in which the notification prohibiting unit prohibits the notification operation by the notification unit of the fact that it has been performed.
Therefore, even if the user receives a message including a keyword, the notification operation such as ringing is not performed by the notification means, and the situation where the user is bothered by receiving the message such as mischief is prevented, and further, the notification is wasted. Waste of battery power due to operation is prevented.
[0008]
In addition to the above function, the present invention is also applicable to a radio paging receiver having message storage means for storing a message received by the receiving means and message display means for displaying the message received by the receiving means. If the received message contains the keyword stored in the keyword storage means, the message conversion means converts the message into other contents and displays it by the message display means.
Therefore, even if a message of mischief or the like is received as described above, a situation in which the user is bothered by the notification operation is prevented, and furthermore, waste of battery power due to useless notification operation is prevented, and the message is displayed. Even if the message is displayed by the message display means, the message is displayed by being replaced with other contents, so that the user is uncomfortable. Feel It is prevented.
[0009]
Further, the present invention is also applied to a radio call receiver having an illustration storage means for storing an illustration in addition to the above function, and the message conversion means stores the message including the registered keyword as an illustration. The image is converted into an illustration stored in the means and displayed on the message display means.
Furthermore, in addition to the above functions, the present invention provides an illustration storage means for storing a plurality of types of illustrations, and an illustration designation for accepting a correspondence between the registered keyword and the illustration stored in the illustration storage means from the user. The message converting means converts the message including the registered keyword into an illustration designated by the user and displays it on the message display means, and is also applied to the input means and the radio call receiver having the illustration. Allows classification by.
[0010]
Furthermore, in addition to the above function, the present invention determines whether the received message including the registered keyword and the message already stored in the message storage means are matched by the message comparison means, and determines the registered keyword. When the received message matches the message already stored in the message storage means, the message writing means overwrites the message already stored in the message storage means and causes the message storage means to store the message. This prevents the storage capacity from being wasted due to duplicate storage of messages.
Furthermore, in addition to the above functions, the present invention, when receiving a message including the registered keyword, discards the received message without storing the received message in the message storage means, This prevents a waste of storage capacity due to duplicate storage of messages.
[0011]
In the present invention, a call signal including a call number and a message is wirelessly received by the receiving means, and the received call number is matched with the call number assigned to itself stored in the call number storage means. This is applied to a radio call receiver for notifying that a call has been made by a notification means when the received call number matches the call number received by the comparison means, and a message is included in the received call signal. The message determining unit determines whether the message is included. If the message is not included, the notification prohibiting unit prohibits the notification operation by the notification unit.
Therefore, even if a mischievous call signal that does not contain any message and only makes a call is received, a notification operation such as ringing by the notifying means is not performed, and a situation where the user is bothered by the mischievous call is prevented. Waste of battery power due to useless notification operations is prevented.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail using an embodiment of a radio selective call communication system using a pager as a radio call receiver.
As shown in FIG. 1, the radio selective calling communication system of this example includes telephones 1A, 1B,..., 1N, a telephone network 2, a central station 3, and base stations 4A, 4B,. And pagers 5A, 5B,..., 5N.
In this system configuration, a call from the telephones 1 </ b> A to 1 </ b> N or another input device (not shown, for example, a mobile phone, a personal computer, etc.) is transmitted to the central office 3 via the telephone network 2.
[0013]
The central station 3 converts the call number and message of the call transmission partner to a protocol suitable for the wireless communication system, and transmits a call signal including the call number and message to the plurality of base stations 4A to 4N. As a protocol suitable for the wireless communication system, for example, POCSAG (Post Office Code Standardization Advisory Group), NTT system, FLEX-TD RADIO Paging System (hereinafter referred to as FLEX-TD) defined in RCR STD-43A However, the present invention can use other formats.
[0014]
The base stations 4A to 4N transmit the data converted as described above as a calling signal as a radio signal at a predetermined data transmission rate (for example, 1600 bps (bits per second), 3200 bps or 6400 bps in FLEX-TD), and When 5A to 5N receives this call signal and detects a signal that matches the call number assigned to itself in this call signal, it notifies the call and displays the content of the received message.
[0015]
FIG. 2 shows the configuration of one of the pagers (radio call receivers with a display function) 5A to 5N used in this example.
Each pager of this example includes an antenna 50 that receives a radio paging signal, a receiving unit 51 that receives radio paging signals transmitted from the base stations 4A to 4N via the antenna 50, and a decoder that decodes the received paging signal. Unit 52, an ID-ROM (readable memory) 53 for storing a self-assigned call number and a frame number to be received, and a ROM storing various programs for controlling each functional unit (Readable memory) 54, (Readable / writeable memory) RAM 55 for storing received messages, a display drive circuit 56 for driving the display unit 57 based on an input signal from the control unit 62, An LCD display 57 for displaying a message and the like, an LED 58 for notifying that a call has been made by light emission, and announcing that there has been a call by pronunciation A sounding unit 59 such as a speaker, a vibration unit 60 such as a vibrator for notifying that a call has been made, a message reading operation, a notification operation stopping operation, a function selecting operation described later, and a keyword And an operation unit 61 for a user to perform an input operation or the like.
[0016]
Here, since the communication system of this example has a diversity format in which data such as a message is transmitted repeatedly in a plurality of frames, the ID-ROM 53 stores the number of the frame to be received. Each pager 5A to 5N receives and processes a frame corresponding to itself based on the frame number. Of course, the present invention is not limited to such a communication system, and can be implemented in various other communication systems.
[0017]
Further, the pager has a control unit 62 that performs overall control of each of the functional units 51 to 61. The control unit 62 also includes a call number and an ID-ROM 53 included in the received call signal. The ID comparison means 63 for comparing with its own call number stored in the message, the message extraction means 64 for extracting the message following the call number from the received call signal when it matches the call number, and the RAM 55 A memory management means 65 for writing data such as a message and a keyword, reading these data from the RAM 55 and performing a predetermined process, and a notification operation by the notification means 58 to 60 when there is a keyword match or a message is not described later. Notification prohibiting means 66 not to be performed.
[0018]
Further, the memory management means 65 stores in the RAM 55 a keyword search means 67 for determining whether or not a keyword stored in the RAM 55 described later exists in the message extracted from the call signal by the message extraction means 64. When the displayed message is displayed on the display unit 57, it has message conversion means 68 for converting the content of the message into a corresponding illustration as will be described later and displaying it.
In this example, each functional unit described above is configured by executing a predetermined program using hardware resources such as a CPU and a memory, but may be configured as a hardware circuit. In the pager of this example, the received message is stored in the RAM 55, and the message is read from the RAM 55 and displayed on the display unit 57 according to the display instruction from the operation unit 61 by the user. May be displayed when a message is received. In this case, the message conversion processing by the message conversion means 68 is performed at the time of display.
[0019]
Further, the RAM 55 stores a message storage area 70 for storing a received message, a keyword storage area 71 for storing a keyword for prohibiting a read notification operation for the received call signal, and a message including the keyword. There is provided an illustration storage area 72 for storing an illustration to be displayed and converted when displaying.
[0020]
FIG. 3 shows an example of the configuration of the message storage area 70. The message storage area 70 is associated with the message number 70a, and a plurality of sets of received message contents 70b and reception times 70c are sequentially set. Store. At the time of message display, the memory management means 65 reads the message contents and the reception times in the order of the new message numbers (that is, the reception time from the newest), and sequentially displays them on the display unit 57.
[0021]
FIG. 4 shows a configuration example of the keyword storage area 71. The keyword storage area 71 is associated with the keyword number 71a, and the keyword content (character string) 71b input by the user, A plurality of sets of illustration contents 71c including keywords and associated with a message are sequentially stored. When displaying the message by the memory management means 65, it is determined whether or not the keyword stored in the keyword storage area 71 is included in the message to be displayed by the keyword search means 67. If it is included, the message conversion means 68 converts the content of the message into an illustration associated with the keyword and displays it.
[0022]
FIG. 5 shows a configuration example of the illustration storage area 72. The illustration storage area 72 stores a plurality of sets of illustration contents (characters, etc.) 72b registered in advance in association with the illustration number 72a. . When the user registers a keyword from the operation unit 61 and an illustration associated with the keyword is designated by the user, the memory management unit 65 reads the contents of the designated illustration from the illustration storage area 72. A copy is stored in the corresponding keyword storage area 71c.
[0023]
Here, the association between the message and the keyword, and further the association between the keyword and the illustration may be realized by associating each data with a pointer, and in this way, the association between the data. The processing required for the processing can be performed quickly and the memory capacity required for the processing can be reduced.
In this example, the user selects a plurality of types of illustrations prepared in the illustration storage area 72 and associates them with the keywords. However, when displaying a message including the registered keywords, the message conversion means 68 The content of the message may be automatically converted into a certain type of illustration. In the present specification, in the present specification, the meaning of the illustration means data for replacement, and this illustration is character string data such as “mischief” in addition to the character. Also good.
[0024]
Further, in this example, it is determined whether or not the keyword registered in the message is included even when the message is displayed, but in the present invention, based on the result of the coincidence determination performed when the call signal is received, The message and the keyword may be associated with each other (that is, when the message is stored), and the conversion display may be performed based on the association without performing the determination process when the message is displayed.
[0025]
Next, the operation of the keyword registration process by the pager having the above configuration will be described with reference to an example of a processing procedure shown in FIG.
First, when the power of the pager is turned on by the user (step S1) and the user selects a function using the operation unit 61 (step S2), the control unit 62 determines whether or not the keyword registration mode is selected. (Step S3). As a result, when a mode other than the keyword registration mode is selected, the selected function process is executed, the process is terminated (step S4), and a call signal reception waiting state is entered.
[0026]
On the other hand, when the keyword registration mode is selected, a keyword for prohibiting the call notification operation input from the operation unit 61 by the user is accepted (step S5), and the keyword is determined by the registration instruction from the operation unit 61. When it is determined that the input of the character string has been completed (step S6), the memory management means 65 registers and stores the input keyword in the keyword storage area 71 (step S7). Note that when a keyword input operation is performed by the operation unit 61, characters are displayed on the display unit 57, and the user inputs a keyword while watching this.
[0027]
When it is desired to display an illustration instead of the message content including the registered keyword, the illustration is selected by the operation of the operation unit 61 by the user (step S8), and the selected illustration is stored in the memory management means 65. Is read from the illustration storage area 72 and stored in the keyword storage area 71c in association with the input keyword (step S9). In the illustration selection operation by the operation unit 61, the illustrations stored in the illustration storage area 72 are sequentially read out and displayed on the display unit 57, and the user selects an illustration while viewing it.
[0028]
Next, processing operations from reception of a message signal to message storage by the pager having the above configuration will be described with reference to examples of processing procedures shown in FIGS. Since the message signal reception process in these processes is common, the same processes are denoted by the same reference numerals, and redundant description is omitted.
In the present invention, any of these processes may be adopted.
[0029]
In the process illustrated in FIG. 7, when a registered keyword is included in the received message, the received message is overwritten and stored in the message storage area 70. In this process, when the reception unit 51 receives a frame including its own call number stored in the ID-ROM 53 in the standby state (step S10) (step S11), the call number of the received frame and the ID-ROM 53 are received. The ID comparison means 63 determines a match with the own call number stored in (step S12).
As a result, when there is no matching call number, the process shifts to a standby state (step S10). When there is a matching call number, is there a message following this call number in the received call signal? A determination of whether or not is made by the message extraction means 64 (step S13).
[0030]
If there is no message, a notification operation is performed by any one or a combination of the LED 58, the sounding unit 59, and the vibration unit 60 (step S16), and a transition is made to the standby state. On the other hand, if there is a message, the keyword search means 67 determines whether or not any keyword is registered by the user in the keyword storage area 71 of the RAM 55 (step S14), and if there is no registered keyword. Then, the received message is stored in the message storage area 70 of the RAM 55 (step S15), a call notification operation is performed (step S16), and a transition is made to the standby state.
[0031]
On the other hand, if there is a registered keyword, the keyword search means 67 determines whether or not the registered keyword is included in the received message (step S17). If the registered keyword is not included, the received message Is stored in the message storage area 70 of the RAM 55 (step S15), a call notification operation is performed (step S16), and a transition is made to the standby state.
On the other hand, if a registered keyword is included, the memory management means 65 determines whether the same message as the received message is already stored in the message storage area 70 of the RAM 55 (step S18). If the same message does not exist, the memory management unit 65 stores the received message in the message storage area 70 (step S19), and the notification prohibiting unit 66 prevents the operation of the notification units 58 to 60 to notify the call. It shifts to the standby state without performing any operation.
[0032]
On the other hand, if the same message already exists, the received message is overwritten and stored in the message number area in which the same message is stored by the memory management means 65 (step S20), and the notification prohibiting means 66 notifies. The operation of the means 58 to 60 is blocked, and a transition is made to the standby state without performing a call notification operation.
Such reception storage processing prevents call notification due to mischief and avoids duplicate storage of messages, so that the storage capacity can be effectively used.
[0033]
In the process shown in FIG. 8, when a registered keyword is included in the received message, the received message is discarded without being stored in the message storage area 70. In this process, the operations in steps S10 to S17 are the same as described above. When the keyword registered in the keyword storage area 71 is included in the received message (step S17), the received message is stored in the RAM 55. The message extraction means (discard means) 64 discards the message without storing it in the message storage area 70 and shifts to a standby state.
Such reception storage processing prevents call notification due to mischief, and avoids unnecessary storage of messages, so that the storage capacity can be effectively used.
In this example, when a message containing a registered keyword is already stored, if the same message has already been stored, it is overwritten or discarded, but for a normal message that does not contain a registered keyword. It is also possible to perform similar processing.
[0034]
Next, the read processing operation of the stored message by the pager having the above configuration will be described with reference to an example of the processing procedure shown in FIG.
In this process, when a read SW (not shown) of the operation unit 61 is operated by the user (step S30), a message designated as a read target of the message storage area 70 is registered in the keyword storage area 71. The keyword search unit 67 determines whether or not the keyword exists (step S31). If the registered keyword does not exist, the memory management unit 65 reads the message content from the storage area 70 and displays it on the display unit 57. The message content is displayed (step S32).
[0035]
On the other hand, if there is a registered keyword, the message content read by the memory management unit 65 from the storage area 70 is converted by the message conversion means 68 into an illustration associated with the registered keyword (step S33). The converted illustration (character or the like) is displayed on the display unit 57 (step S34).
When the selection SW of the operation unit 61 is pressed during display of this illustration or message (step S35), the memory management means 65 determines whether or not there is a next message to be displayed in the message storage area 70. If there is a message to be displayed next (step S36), the process proceeds to step S501. If there is no message to be displayed, the message reading process is terminated.
[0036]
As described above, when a registered keyword is present in a message, it is converted into an illustration and displayed, so that it is possible to reduce discomfort that a user feels when viewing the message display screen.
In this example, when the message is displayed, the message including the registered keyword is converted into an illustration and displayed. However, when the message is stored, the message including the registered keyword is converted into an illustration and stored in the message. It may be stored in the area 70 and the conversion process may be omitted when the message is read and displayed.
[0037]
FIG. 10 shows an example of a processing procedure in which no call notification is performed when no message is included in the received call signal.
This processing is performed by the pager having the configuration shown in FIG. 2, but the cooperation between the message extraction unit 64 and the notification prohibition unit 66 is changed, and there is no message in the call signal received by the message extraction unit 64. (Step S13), the notification prohibiting means 66 shifts to the standby state without performing the notification operation by the LED 58, the sound generation unit 59, and the vibration unit 60. Since the other processes are the same as those shown in FIG. 7, the same reference numerals are given and description thereof is omitted.
[0038]
In this way, regardless of the presence or absence of registered keywords, when there is no message in the received call signal, call notification is not performed, and the user is not bothered by a call that does not require confirmation.
Of course, such a process can be applied in the same way as the process shown in FIG. 8, but it is performed alone in the radio call receiver without using the call notification process based on the presence or absence of the registered keyword. In this case, the above-described effects can be obtained.
[0039]
【The invention's effect】
As described above, according to the present invention, since a keyword such as an uncomfortable word is registered in the memory in advance by the user, a call operation is not performed even if a message including the registered keyword is received. In addition, it is possible to prevent the user from being bothered by call notification due to mischief or the like, and further, it is possible to prevent the waste of limited power and message storage capacity.
Further, when displaying a message including a registered keyword, it is converted into a pre-registered illustration and displayed, so that user discomfort can be reduced.
