Abstract

PURPOSE:To make it possible to register a message from a transmitting side to a receiving side and to make it unnecessary to increase the storage capacity of an EEPROM by reading out and displaying a protection message to which management information is added out of registered contents. CONSTITUTION:At the time of detecting a call to a self-receiver, a control part 102 informs the existence of the call to its user by an informing function part 107. Simultaneously the control part 102 stores message information reproduced from a selection signal in a memory part 105 and sends the information to a display part 106. Prior to the storage of the information in the memory part 105, the control part 102 detects a header including a free routine sentence registering code from a reproduced signal. At the time of detecting the header, its corresponding free routine sentence is registered in a registering area of the EEPROM 103 as a protection message. At the time of detecting a header for developing a free routine sentence, its corresponding free routine sentence is developed in the message information stored in the ROM 103. Plural kinds of free routine messages are registered as protection messages and an optional message is selected and displayed by an operation part 104.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver with a display function, and more particularly to a radio selective call receiver with a display function having functions for registering, receiving and displaying free-form text.

[0002]

2. Description of the Related Art Conventionally, a device of this type can send a simple comment by using numbers or alphabets, but it is not practical to send a text because of restrictions of transmission capacity and other factors. Therefore, a plurality of fixed phrases are prepared on the receiving side, and the required fixed sentence is called by sending the fixed phrase number on the transmitting side, and the sentence of the fixed phrase is displayed. In this case, there are two types of fixed phrases, free fixed phrases and fixed fixed phrases. A fixed phrase is a fixed sentence that everyone uses, such as "please call me," and multiple sentences are registered in the ROM from the beginning, so that the mobile phone cannot rewrite it. There is. For example, as a message, “1234-567
8) was transmitted, and if the fixed phrase "Please call me" was selected from the registered fixed phrases, the sentence "1234-5678 Please call" was transmitted. Become. In this case, what is actually transmitted is only the comment "1234-5678" and the information for selecting the fixed fixed sentence "Please call me", and the transmission amount is larger than the case where the whole sentence is transmitted as a message. Is less. On the other hand, the free-form text is a fixed text that the carrier arbitrarily registers, and proper nouns such as place names and project names, and frequently used texts or telephone numbers are arbitrarily registered and used. If the other party is informed of the registered contents in advance, the other party can transmit the necessary sentence by sending a message together with a message indicating which of the free-form texts to use when calling. That is, by using the free-form text, a text suitable for the wearer can be expressed.

Free-form text is generally rewritable by a ROM writer or a switch operation, and is stored in an EEPROM whose stored contents are not lost even when power is not supplied. Also, among the received messages, the ones that the carrier wants to register are EERP by switch operation.
You can also register with OM. As a technique similar to the registration of the free-form text, there is a technique of registering a protected message of received messages. The protected message is used in the case of a particularly important message, and informs the carrier of the time when the message is received, the number of times of reception, the registered address, etc. in addition to the message using the free-form text. One of the protection message registration methods is a priority call priority memory protection means that performs a process in which, when a message having a priority call identification code, that is, a header of a protection message is received, the memory is not erased unless the carrier performs an erase operation. What is possessed is JP-A-3-9332.
No. 5 is disclosed. With this method, the message can be registered from the sender to the receiver. However, this priority call is stored in the message memory part using RAM, and when the battery is completely exhausted,
The message registered as a priority call also disappears. Another method of registering a protected message is that, when a message in which a secret code following a special symbol is added to the head of a received message is received, an area for storing the received message information is separately provided in the EEPROM. , Japanese Patent Laid-Open No. 4-312033. In this case, in addition to the sent message, information such as the reception time, the number of times of reception, and the storage address is also stored.

[0004]

As described above, in the method of registering the free-form text by operating the switch of the ROM writer or the carrier himself, the free-form text cannot be registered from the sending side of the paging system. , There is little freedom in how to register free-form phrases. Also, in the case of a protected message for registering a message from the sending side in the EEPROM of the receiving side, since the EEPROM is originally used for registration by the carrier, if the storage area is allocated for the protected message, the original registration Since the storage area is reduced, there is a problem that it is necessary to increase the storage capacity for this purpose. The present invention has been made in view of such a situation, and enables a message to be registered from a transmitting side to a receiving side, and even in that case, it is not necessary to increase the storage capacity of the EEPROM. is there.

[0005]

In order to solve such a problem, the invention of claim 1 adds management information to the read free-form text and adds it as a protection message as an EEP.

02, step 204), and when the selection signal includes a fixed text expansion header, if the fixed text expansion header specifies a free fixed text, the EEPROM specifies the fixed text expansion header. Fixed sentence expansion means (steps 207 and 208 in FIG. 4) for reading a fixed fixed sentence and reading the fixed fixed sentence from the ROM if the fixed fixed sentence is specified by the fixed sentence expansion header. The display means (the message display unit 106 in FIG. 1) for displaying the fixed phrase expanded by is provided. According to a third aspect of the present invention, in the second aspect, the free-form sentence registration header includes a free-form sentence registration code indicating that the free-form sentence is registered, and a plurality of free-form sentences stored in the EEPROM. It has a free fixed sentence number that specifies which. According to the invention of claim 4, in the invention of claim 2 or claim 3, the free-form text registration permission / non-permission judgment means for judging whether or not the free-form text specified by the received selection signal can be stored in the EEPROM ( 4) and display means for displaying the result of judgment by the free fixed text registration possibility judgment means in addition to the free fixed text.

[0006]

According to the first aspect of the present invention, all free-form texts are stored in the EEPROM as a protection message, and it is determined whether they are used as a protection message at the time of reading or as a simple text. According to the second aspect of the present invention, the free-form texts selected from the transmitting side are registered in the EEPROM, and the registered free-form texts are selected and displayed. According to the invention of claim 3, a designated free fixed phrase is registered. According to the invention of claim 4, it is determined whether the EEPROM can store the free-form text and the result is displayed.

[0007]

1 is a diagram showing the configuration of an embodiment of the present invention, in which a signal received by a radio receiving section 101 is supplied to a control section 102, decoded by a decoder of a control section 111, and a decoded message is displayed. Is stored in the message memory unit 105, is displayed on the message display unit 106, and the notification function unit 107 notifies that the message has been received. Further, when a header is received following the message, and when a free-form text is specified by the information contained in the header, the specified free-form text is read from the EEPROM 103 and is combined with the message. The message is stored in the message memory unit 105 and further displayed on the message display unit 106. When the fixed fixed phrase is specified by the header, the fixed fixed fixed phrase which is specified is read from the ROM 112 and is displayed in the same manner as described above.
Reception is notified.

When the header is composed of a free-form message registration code and a free-form message number, a sentence designated by the free-form message number is combined with the message and stored in the message memory unit 105, and received. Management information such as time and the number of times of reception is added and registered in the EEPROM 103 as a protection message. At this time, if a plurality of protection messages are registered, one of them can be selected and displayed by the switch operation unit 104.

2 and 3 are diagrams showing the signal format of the selection signal. FIG. 2A shows an example in which only a message is sent, and the message information is sent following the ID which is the calling number information. In this case, the message is stored in the message memory unit 105, and the content is stored in the message display unit 10.
6 is displayed and the notification function unit 107 notifies that the message has been received.

FIG. 2B shows an example of displaying a fixed phrase between messages. In this case, the fixed phrase can be read by sending a header. The header consists of a fixed phrase expansion code to identify to the receiving side that what is sent later is not a message but a fixed fixed phrase or free fixed phrase, and then a fixed phrase number for reading the fixed phrase. , The fixed phrase at this time may be a fixed fixed phrase or a free fixed phrase. For example, if the first message is "1234-5678", the fixed text read by the header is "please call me", and the last message is "MURAYAMA". The information displayed is "1234-5678, please call MURAYAMA". The fixed phrase numbers are, for example, 01 to 20 for free fixed phrases and 2 for fixed fixed phrases.
1 to 50 are used, and "---" is used as the fixed phrase expansion code.
It is designed to send the symbol. Therefore, on the receiving side, "-
It is understood that the two-digit number after receiving the "-" signal is the fixed phrase number, and the free fixed phrase or the fixed fixed phrase is read and displayed by the number.

FIG. 2C shows a signal format when registering a free-form text, in which case a header is sent to the beginning of the message. The header is composed of a free-form sentence registration code and a free-form sentence number. For example, a symbol "]]" is used as the free-form sentence registration code, and the symbol is followed by any of the free-form sentence numbers 01 to 20. Numbers will be sent. Since a message is sent after that, the message is added after the specified free-form text and EEPR
It is recorded in an empty position in the protected message area of the OM 103. The vacant position is determined by the control unit 102.

All free-form texts registered by the header are registered as protected messages, and the reception time, the number of receptions,
The management information such as the address where the message is stored is also registered. As of this, the protection message is registered both the sentence and the management information at that time of freedom boilerplate. Therefore, both are displayed when this is displayed. This is all right when management information is also needed, but when it is not necessary and only the text content is needed, extra information is displayed and the page increases and it becomes difficult to see.
Therefore, it is more convenient to select whether to display only the text content or the management information. For this reason, when reading this, the carrier displays the read text together with all of the reception time, the number of times of reception, the address storing the message, etc., that is, the protection message, or displays only the read text. This can be selected by the switch unit 104. Switch part 10
Reference numeral 4 has a menu switch, a Δ switch, a ▽ switch, etc. The message is read by pressing the △ or ▽ switch, and the menu is displayed by pressing the menu switch. Then, the ▽ switch increments the menu item, and the ∆ switch shifts to the operation of the menu item being displayed. The menu items include display items such as free-form text display and protected message display. When the free-form text display item is selected, press the △ switch to read information other than management information and display the free-form text in the message display area. indicate. Further, when the protection message display item is selected, the protection message to which the management information is added is read out by pressing the Δ switch and displayed on the message display section. In the normal standby mode, the latest or oldest message is displayed by pressing the △ or ▽ switch. FIG. 3 shows the above application example, which is an example in which a plurality of fixed phrase expansion codes are sent after the free fixed phrase is registered, and the fixed phrase expansion code may be located at any position.

When the wireless receiver 101 of this apparatus receives a selection signal from a base station of a paging system (not shown), the wireless receiver 101 sends the selection signal to the decoder 111 of the controller 102. The decoder 111 receives the received ID number and its own ID stored in the EEPROM 103 in advance.
Match the number. When these call numbers match, the control unit 102 detects that there is a call, and notifies the wearer that there is a call by the notification function unit 107 including at least one of a speaker, a light emitting diode, a vibrator, and the like. To do. At the same time, the control unit 102 stores the message information reproduced from the selection signal in the message memory unit 1.
In addition to being stored in 05, a message based on this message information is displayed on the message display unit 106.

Before storing the message information in the message memory unit 105, the control unit 102 detects whether or not the reproduced signal has a header containing a free-form text registration code. When there is a header including a registration code of free-form text information, the control unit 102 registers the free-form text corresponding to this header in the free-form text registration area of the EEPROM 103 as a protection message. Further, when the expansion header of the free-form text is included, the free-form text corresponding to this header is expanded from the EEPROM 103 into the message information. Since a plurality of free fixed phrases can be registered as the protection message, any one of them can be selected and displayed by the switch operation unit 104. At this time, the wearer operates a switch to decide whether to display all the texts consisting of the message and the fixed text and the accompanying protection time such as the recording time as the protection message, or whether to display only the text consisting of the message and the fixed text. It is determined by operating the section 104.

As described above, when a free-form sentence is registered, all of the free-form sentences are registered in the EEPROM as protection messages, so that the free-form sentence can be registered from the transmitting side to the receiving side, and all free-form sentences are registered. Because it is done
The carrier himself does not need to register the received message in the EEPROM. Therefore, the EEPROM does not need to prepare an area for a protected message and two areas for storing a received message in the EEPROM at the will of the carrier as in the conventional case, and the storage area of the EEPROM can be effectively used. Moreover, the EEPROM 103 is set as a free-form text so that important messages are not overwritten.
By storing in the memory, it is possible to prevent important messages from being lost due to the exhaustion of the power supply. In this case, E
When the data is recorded in the EPROM, the limit of the storage capacity is reached soon, but at this time, the user can delete the free-form text or the protection message by the switch operation. As for this deletion, there is an item of individual deletion of free-form text or individual deletion of protected message in the menu as shown in Fig. 5. If you specify either of these items, a list of registered contents will be displayed, and unnecessary ones will be displayed. I have selected to delete.

Next, the operation of the embodiment when the fixed text information is received will be described with reference to the flow chart shown in FIG. When the control unit 102 detects a call to itself from the selection signal,
The free fixed text processing operation is started, and it is detected whether or not the message information received in step 202 includes a registration header of the free fixed text. If the registration header is included, the EEPR is determined in step 203.
It is checked whether or not the free-form text can be written in the OM 103. That is, it is checked whether or not the carrier permits rewriting of the free-form text in the EEPROM 103.

When the data can be written in the EEPROM 103, the control unit 102 proceeds to EE as shown in step 204.
The text of the free-form sentence number designated by the header in the PROM 103 is read from the EEPROM 103 and registered in the free-form sentence area of the same EEPROM 103 together with the information as a message and a protection message. Subsequently, the control unit 102 deletes the registration code of the free-form text and adds and displays a comment "Tooku OK" after the free-form text developed in the message information. Therefore, the carrier can know that the received signal has been registered by confirming the display of “TOOKOU OK”.

On the other hand, in step 203, EEPR
When the OM 103 is set so that the free-form text cannot be written, the control unit 102 sends the free-form text to the EE.
Without registering in the PROM 103, the registration header of the free-form text is deleted, and, as shown in step 206, a comment of "TOROKU NG" is added after the free-form text message expanded in the message information.

In step 202, when there is no header for registering the free-form text, the control unit 102 determines in step 20.
As shown in 7, it is checked whether or not there is a fixed sentence expansion code in the message information. If there is a fixed phrase expansion code, the control unit 102 deletes the fixed phrase expansion code from the received message and expands the fixed phrase corresponding to the fixed phrase number in the message information as shown in step 208.
In this case, the fixed phrase is read from the ROM 112,
The free-form text is read from the EEPROM 103. If there is no fixed phrase expansion code in step 207, the operation immediately proceeds to step 209.

After the processing in any of steps 205, 206 and 208 is performed, or after it is determined in step 207 that there is no fixed sentence expansion code, is there any free memory in the message memory unit 105 shown in step 209? Check whether or not. If there is no free memory, the control unit 102 erases the oldest message stored in the message memory unit 105 and registers the received message information in this message area, as shown in step 210.

If the message memory unit 105 has an empty memory, the received message is registered in this empty message area as shown in step 211.

[0022]

As described above, according to the present invention, since all free-form texts are registered in the EEPROM as protected messages, the message can be registered from the sending side to the receiving side and the battery consumption is also registered. Message can be secured. In addition, the EEPROM is used as an area for protection messages,
Since it is not necessary to divide the received message into areas for the carrier to register, it is only necessary to select whether to read the registered protected message as a protected message or to read only the message.
This has the effect that the storage area can be effectively used.
