Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message erasing method for a radio selective calling receiver and a message receiver.
The present invention relates to a radio selective call receiver having a message storage function, a message erasing method, and a message receiver.

[0002]

2. Description of the Related Art Conventionally, there has been a radio selective call receiver, also called a pager or a pager, which has a function of displaying and storing a message. The selective calling signal sent from the base station is received by a radio circuit via an antenna, demodulated by a demodulation circuit, and input to a control circuit. In the control circuit, an individual number code (ID code) included in the reception selection calling signal and an individual number code memory (ID-RO) are stored.
M) against the ID code of the own device stored in advance in
If both codes match, it is determined that a call to the own device has occurred, a call notification instruction is output, a sound signal is generated by the drive circuit, a sound is output from the speaker, and The fact that a call has occurred is reported.

When a message code is included in the reception selective calling signal, the control circuit first performs error correction and decoding of the message code, and the message code is displayed on a display, and the displayed message is displayed. Is deleted when a display stop operation is performed or when a certain display time has elapsed. The received message code is transferred from the control circuit to a message memory (M-RAM),
It is memorized. The message code is read from the message memory and displayed on the display when the display switch is displayed by the owner after the display of the message is completed.

[0004] Thereafter, every time a call is made to the own device, the message code inserted in the selected call signal is displayed and stored in the message memory. When the message memory becomes full, the oldest message code is replaced with a new message code.

A method for erasing a message code in one message memory is disclosed in Japanese Patent Application Laid-Open No. 3-147431. According to this publication, in the selective call receiver, there is provided a clocking means for performing a clocking operation, and erasing information specifying means for inputting information relating to the erasing timing of the message code. It is described that the message code is deleted from the memory in response.

[0006] Japanese Patent Application Laid-Open No. Hei 5-30018 discloses that
The document describes that a time setting means for setting a predetermined time and an input means for inputting erasure prohibition information are provided, and erasure of specific message information stored in a message memory is prohibited until a predetermined time. .

As described above, there are various methods for erasing message information from the message memory. That is, (1) a batch erasing method for simultaneously erasing all unprotected messages by a switch operation, (2) an individual erasing method for individually erasing messages for each message information by a switch operation, and (3) a message memory. There is a method in which the oldest message is deleted every time a new message arrives when the capacity is full.

[0008]

However, in recent years,
The radio selective call receiver has become the mainstream of the information reception service rather than the individual call, and the number of messages received per day is enormous, and with the increase in received messages,
The memory capacity has also increased, and the number of messages that can be stored in the receiver has increased from several hundred to several thousand. In the radio selective calling receiver, the above three methods have the following problems. Had. That is, as means for erasing received messages, there are a batch erasing method, an individual erasing method, and an oldest message erasing method. However, it is troublesome to delete all data after protecting them. Further, in the individual erasure method, since the number of information messages is too large, it takes too much time to erase one message at a time. In the oldest message erasing method, a message that one wants to keep is also erased.

In particular, information receiving services such as news and weather forecast are distributed in dozens of times a day and stored in a message memory. However, it is troublesome to delete a message stored in the memory, and the memory capacity is reduced. For large receivers, old information messages will remain forever.

[0010] The present invention provides a new message erasing method to address such a problem. That is,
The freshness of an information message does not last for many days (depending on the type of information, of course), and it is also free from the hassle of deleting messages, so messages can be partially and collectively deleted at certain time intervals. It is like that.

At a predetermined time, the arrival time information such as a time stamp added to the message stored in the memory of the radio selective calling receiver is compared with a clock function by a comparison circuit, and a message satisfying a certain condition is obtained. From the memory.

[0012]

According to the present invention, there is provided a message erasing method for a radio selective call receiver with a display having a clock function, wherein the erasing of a message stored in a storage unit is performed for each predetermined information genre of the message. It is characterized in that it is performed collectively at a preset time.

[0013] Further, in the above-described message erasing method for a radio selective calling receiver, a protection designation is further set to the message, and the message is erased excluding the message with the protection designation.

According to another aspect of the present invention, in a message receiver with a display having a clock function, a message memory for storing a received message, protection setting means for setting a protection designation to the message, and erasing the message Erasure setting means for setting a time to perform, classification means for classifying the message according to the attribute of the message, display means for displaying the message, the protection designation and the attribute of the message from the message memory The message is deleted according to the message deletion time.

Further, the present invention provides a radio selective calling receiver having a display unit, particularly a radio selective calling receiver having a function of receiving various information (information receiving service) provided by an operator in addition to an individual call. , A means for erasing a received message is provided. Here, the freshness of the information message does not last for many days (depending on the type of information, of course), and is free from the trouble of deleting the message. It is designed to be erasable. In this case, at a fixed time, a comparison circuit compares the arrival time information such as a time stamp added to the message stored in the memory of the device with the clock function, and deletes a message satisfying a certain condition from the memory. I do.

Embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment] FIG. 1 is a block diagram of a radio selective call receiver (hereinafter, referred to as a receiver) according to a first embodiment of the present invention. FIG. 2 shows a message erasing method according to an embodiment of the present invention. FIG. 3 shows a flowchart of an embodiment of the present invention.

(Configuration of the Present Embodiment) The configuration of a receiver according to an embodiment of the present invention will be described. FIG. 1 is a block diagram of one embodiment of the present invention.

In FIG. 1, after a radio signal received by an antenna 1 is amplified by a radio section 2 at a high frequency,
Demodulated to baseband signal. The demodulated baseband signal is shaped and converted by the waveform shaping circuit 3 into a waveform readable by the control unit 4. The control section 4 compares its own call number, which is written in advance in a writable read-only memory (ROM) 5, with the call number received from the waveform shaping circuit 3. The message code is stored in the memory RAM6.

When both the own calling number and the received calling number coincide with each other, the control unit 4 notifies each of the amplifying circuits 9, 11, and 13 in order to notify the calling.
The notification is made to the wearer by the speaker 10, the vibrator 12, and the LED 14.

The message is displayed on the display unit 8 via the display driver 7. The receiver is operated by a power supply 15 and a clock oscillating unit (CLK) 16, 17 is a power switch, and 18 and 19 are switches for inputting a message erasing time and the like. A comparison unit 20 operates by a clock function 21 of the control unit to compare a preset time at which a message is to be deleted with the current time, and to delete the message stored in the memory if the time matches. is there.

The inside of the control unit 4 is further divided into the following blocks as shown in FIG. The time at which the message set by the carrier is erased is stored in the set time memory 101, and is compared with the time keeping circuit 102 of the apparatus by the comparison circuit 10
Compare at 3. If they match, a control signal is sent to the memory control unit 104. The memory control unit that has received the control signal deletes the message data stored in the RAM 6.

FIG. 3 shows a display example of a message before and after a message erasing operation according to the message erasing method of the present invention.

In the present embodiment, at 12:00 (noon) every day, the information messages up to the previous day are deleted.

In FIG. 3, in the <list of received messages before deletion>, 201 is a message number which is numbered in the order of the arrival time, and those with [] are [4] (202). This means that erasure is protected.

Reference numerals 203 and 204 denote time stamps of the arrival time of the message, which indicate the arrival date and time, respectively. Reference numeral 205 denotes the content of the message.

With respect to these messages, according to the erasing method of the present invention, at the designated time of 12:00, unprotected messages up to the previous day are automatically and collectively erased, and
Message list after deletion>.

In order to delete all unprotected messages up to the previous day, a message arrives on the previous day (9/22) and the protected message “GGGGGGGG” (206) and today (9/2)
3) Incoming messages remain and all others are deleted.

FIG. 4 shows the operation on the time axis in the message erasing method of the present invention. In the figure,
J, I, H, etc. (251) indicate the message and the message arrival time, and the message content (205) in FIG.
Is linked to. Now, the time is 12:00 on September 23
If it is (noon), the message of the message received by the previous day (shaded portion of 253) is deleted. However, protected messages [4: GGGGGGG
G] remains.

(Operation of the Present Embodiment) Next, the operation of the receiver according to the embodiment of the present invention will be described. FIG. 5 shows a flowchart of an embodiment of the present invention.

In the receiver, the power switch 1
7 is turned on (301), and the reception standby state (302)
Then, the current time of the clock function of the receiver is compared with a preset time at which messages are automatically deleted at once (303). When the current time has reached the set time (Y in 303), if there is no message arriving at the receiver (N in 304), the process returns to the standby state without deleting the message. When there is a message (3
04, Y), the message is deleted from the message whose reception time is old.

In the present embodiment, the message numbers (201) shown in FIG.
n.

In this case, first, it is confirmed whether the message having the earliest arrival time (message # 1) among the messages stored in the memory is designated as a protected message (305). If the protection is designated, this message is left as it is, and it is determined whether there is a next message (308).

On the other hand, if there is no protection designation (N in 305), the message arrival time is confirmed. If the incoming time is before 0:00 of the previous day (Y in 306), the message # 1 is deleted from the memory (307), and the process proceeds to search for a message with the oldest received time (308). If the incoming time is after 0:00 of the previous day (N in 306),
It returns to the standby state.

Here, the message erasing process is performed in the order of the oldest arrival time, and the messages after the message # 2 have the newer arrival time than the message # 1.
Since the incoming time is after 00, the message is not subject to the erasure message, so there is no need for erasure processing.

When message # 1 erasure processing is completed as described above, the arrival time of the message # 1 is shifted to the next oldest message. If there is no next message, the process returns to the waiting state (N in 308).

It is confirmed whether the next message # 2 is designated as a protected message (309). If the protection is designated, this message is left as it is, and it is determined whether there is a next message (312).

On the other hand, if protection is not specified for message # 2 (N at 309), the message arrival time is confirmed. Since the message erasing process is performed in the order of the arrival time, the arrival time is later than that of the message # 1. If the incoming time is before 0:00 of the previous day, (31
0, Y), delete message # 2 from memory (311)
Then, similarly to the case of the message # 1, the process proceeds to search for a message having the next oldest reception time (312).

If the incoming time is after 0:00 of the previous day (N in 310), the process returns to the standby state.

When the erasing process of the message # 2 is completed,
The incoming message moves to the next oldest message (messages # 3, # 4,...), And the same processing is performed in order.

Finally, the message # with the latest arrival time
n is performed. It is confirmed whether the message #n is designated as a protected message (313). If the protection is designated, this message is left as it is, and the process returns to the original standby state (313). If the arrival time of this message is earlier than 0:00 of the previous day (Y at 314), the message #n is deleted from the memory (315), and the process returns to the standby state, and the arrival time is changed from 0:00 of the previous day. In the latter case (N in 314), the process returns to the original waiting state while leaving the message in the memory.

In this way, the preset today's
At 12:00, for messages arriving before 24:00 on the previous day, messages without protection designation stored in the message memory are sequentially deleted. The set point and the erase set time may be different from those in the above-described embodiment, and when the capacity of the message memory is large, the erase time of the memory may be further increased and the erase interval may be further increased from the present time.

Further, according to the present embodiment, the protection designation message may be deleted from the message memory according to the self-selection.
A switch for canceling the protection designation may be provided. In this case, for example, if the time setting switch or the protection designation switches 18 and 19 shown in FIG. Various functions can be set with functions.

In the above-described embodiment, the radio selective calling receiver is described. However, the above function is not limited to the radio selective calling receiver, but in recent years, the above functions are applied to PHS (Personal Handyphone System) and PDC (Personal Digital Cellular). It may be set, and not limited to mobile devices, the above function is provided in a data communication device having a limited memory capacity of a message memory, a home telephone, or a message receiver having a function of receiving a message, so to speak. Of course, it is good. In these cases, the setting of the erasure setting time, the setting of the protection designation, and the like can make use of the advantage that the number of setting switches is small.

Further, the message memory need not be limited to a RAM that specifies a semiconductor RAM for temporary storage, and may be used as another data storage area if it is a storage area for storing a message. The message may be stored as a message code stored in the received baseband signal or as input data of a display driver for driving the display. The smaller the code as the data amount, the smaller the storage capacity and the longer the erasure setting time can be set retroactively.

In the above message, a message for which protection has been designated can be deleted from the time when the user releases the protection designation. The protection designation can be released by, for example, cyclically setting the switch for which the protection designation is made, and can be easily released and erased.

[Second Embodiment] In the first embodiment, the condition for deleting a message is only the arrival time, but the second embodiment will be described as follows.

In recent years, since the amount of messages for information reception has increased, some receivers have a function of storing a message for each information genre. With such a message storage, there are genres whose genre is desired to be stored in the memory for a while and genres which may disappear on the next day such as a weather forecast.

For these, a message erasing time can be designated for each genre. FIG. 6 shows a genre name (401) and a header (402) for each genre with regard to genre-specific message elimination of the present embodiment.

Each received message has a header part and a data part.
A D number or the like is specified, and the header is used to categorize each genre.

FIG. 7 shows an example of message deletion according to the present invention on the time axis. Now, when the time reaches the designated time 12:00 (451), message deletion processing is performed for each genre. "News" sets the erasing time to the previous day, "Weather Forecast" sets the erasing time to 12:00 of the previous day,
Each can be set for each message genre.

The condition of the time range for deleting the message is different for each genre, and the setting is input in advance by the switch operation by the carrier (452).

As a deletion operation, a header for identifying a genre is searched for, and when a message having the header is found, the incoming time is compared with a set time. If the conditions are met (when it is determined that this message is to be deleted), this message is deleted from the memory. This process is performed on messages in all genres based on the header of the message.

This processing is performed from “news” of the genre.
"Fortune-telling", and the message in the shaded portion shown in FIG. 7 is eventually deleted.

For example, in the case of "news", at 12:00 on September 23 (453), the shaded message shown in FIG. 7 is deleted. In the “weather forecast”, at 12:00 on 9/23 (454), the shaded message shown in the figure is deleted. Similarly, for "sports" and "divination", messages in the time range set for each genre are deleted.

In the present embodiment, it is possible to delete a message from the message memory according to the deletion setting time for each genre. However, if a protection is designated for each message, the presence or absence of the protection designation is searched for each genre. do it,
If protection is specified, the message is left in the message memory and erased at a desired erase set time.

[0057]

According to the present invention, the erasure of the received message is collectively erased at a fixed time, so that the trouble of erasing the message is eliminated. In addition, since old messages that have not been seen do not remain in the memory forever, the number of messages stored in the memory decreases, search becomes easy, and usability can be increased.

Further, since the erasing time of the received message can be set separately for each genre, even if a large number of messages are received, the messages can be easily collected and the messages can be understood more quickly.
