DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio receiving apparatus , and more particularly to a radio receiving apparatus which reads out a character string corresponding to a sentence code number included in a received message signal from a storage unit and displays it on a display.

[0002]

Conventionally, in the Viewing function radio selective call receiver, multi-character strings stored in the storage unit is fixed in the system as a so-called fixed phrase, the caller, a predetermined A message is assembled by selecting some necessary fixed sentences from among various fixed sentences, and a sentence code number sequence corresponding to the assembled message is sent to the receiver carrier.

[0003]

According to the radio selective call receiver as described above, it is not necessary to convert each character of the message to be transmitted into a code number and input it, but only to transmit a few sentence code numbers. Thus, there is an advantage that a relatively long sentence can be notified to the receiver carrier. However, there are the following problems.

(1) Since usable character strings are fixed in the system as fixed sentences, the contents of messages that can be notified to the receiver carrier are limited. For this reason, the content of the notification tends to be insufficient, and in many cases, the receiver carrying the notification has to contact the caller by telephone.

[0005] (2) In order to notify a message that cannot be expressed by a combination of fixed phrases prepared by the system, the message is a content frequently used between a specific caller and a specific receiver carrier. Every time,
The caller must convert each character constituting the message into a code number one by one and input the code number from a touch phone or the like. For this reason, the calling operation becomes complicated and an input error easily occurs due to an increase in the number of inputs. Also, since the content of the message cannot be confirmed, even if a message with the wrong content is sent, it is often not noticed. Further, when the number of code numbers that can be input for one call is limited, it is necessary to call a plurality of times.

The present invention has been made to solve such a conventional problem, and a first object of the present invention is to make it possible to change a character string which can be notified by one sentence code number to an arbitrary character string. .

A second object of the present invention is to provide a radio receiving apparatus which can be utilized at the time of calling, and which can confirm in advance the contents of a message to be notified at the time of calling, and input a sentence code number corresponding thereto. Wireless that can definitely be done

When the user performs an operation related to quoting a character string on the input device c, the character string registration means e reads out the quoted character string from the storage unit a and displays it on the display b. After the necessary citations have been completed and the user has assembled the contents of the message to be notified on the display b, the conversion means g converts the character string displayed on the display b into the corresponding sentence code number. Then, the dial sound generating means h converts the sentence code number into a dial sound and outputs it. This dial tone can be used as an input of a sentence code number when calling from a telephone.

[0012]

Next, embodiments of the present invention will be described in detail with reference to the drawings. Referring to FIG. 2, the radio selective call receiver with a display function of the present embodiment includes an antenna 1, a radio unit 2, a decoder 3, an EEPROM 4 for storing its own radio selective call number, a control unit 5, a memory 6, a numeric keypad, and the like. Keyboard 7, an LED drive circuit 8, an LED 9, a speaker drive circuit 10, a speaker 11, a dial sound signal generator 14, an LCD drive circuit 12, and an LCD 13.

Referring to FIG. 3, a memory 6 includes a fixed phrase storage area 61 for storing predetermined fixed phrases (character strings) fixed in the system in correspondence with a predetermined sentence code number. Arbitrary fixed phrase storage area 62 for storing an arbitrary fixed phrase (character string) in association with an arbitrary sentence code number
And a message storage area 63 for storing a received message, and a sentence creation information storage area for storing information necessary for creating an arbitrary fixed phrase, for example, a correspondence table of a combination of a numeric key inputted from the keyboard 7 and a character type. 64
And

Next, a more detailed configuration and operation of the radio selective call receiver with a display function of the present embodiment configured as described above will be described. First, an operation when an arbitrary fixed phrase is created and registered in the arbitrary fixed phrase storage area 62 of the memory 6 will be described. In this case, as shown in FIG. 4, the user first creates an arbitrary fixed phrase (step S1), and then registers it (step S2).

In the creation of an arbitrary fixed phrase in step S1, the user operates the keyboard 7 to set the receiver in an arbitrary fixed phrase creation mode, and to enter each character in the character string to be registered as an arbitrary fixed phrase from now on. A corresponding combination of numeric keys and the like are sequentially input from the keyboard 7. At this time, the control unit 5 stores the sentence creation information storage area 6 in the memory 6.
4 is converted to the corresponding characters by referring to the sentence creation information in 4 and the characters are sequentially converted to LC.
The data is sent to the D drive circuit 12 and displayed on the LCD 13. When the desired character string has been created on the LCD 13, the user proceeds to the registration of step S2, switches the receiver to the arbitrary fixed-state sentence registration mode, and inputs the corresponding sentence code number from the keyboard 7 to register. To instruct. In response to this, the control unit 5 stores the character string displayed on the LCD 13 in the arbitrary fixed-form sentence storage area 62 of the memory 6 in association with the input sentence code number.

Next, the operation of the receiver when receiving a message will be described. In FIG. 2, a radio signal received by an antenna 1 is amplified and demodulated by a radio unit 2, converted to a digital signal, and sent to a decoder 3. Decoder 3
The control unit 5 compares the wireless selective call number read out from the EEPROM 4 with the wireless selective call number included in the digital signal, and when they match, notifies the control unit 5 of the coincidence. Activates the LED drive circuit 8 to blink the LED 9 or / and activates the speaker drive circuit 10 to generate a sound from the speaker 11. In addition, when the verification is successful, the decoder 3 receives the message following the radio selective calling number and notifies the control unit 5 of the message.

Referring to FIG. 5, in the received message, each sentence code number N1, N2,... Is prefixed with a sentence code number of a fixed form sentence or a sentence code number of an arbitrary fixed form sentence. Identifiers C1, C2,.
Is added.

Referring to FIG. 6, when receiving a message from decoder 3, control unit 5 stores it in message storage area 63 of memory 6 (step S11).
Next, a set of an identifier and a sentence code number are cut out from the message, and whether the sentence code number is a sentence code number of a fixed sentence or a sentence code number of an arbitrary fixed sentence is identified based on the identifier (step S12). . If it is the sentence code number of the fixed sentence (NO in step S12), the sentence code number is read out by reading the fixed sentence stored in the fixed sentence storage area 61 of the memory 6 corresponding to the sentence code number. It is converted into a sentence (step S13). On the other hand, if the sentence code number is an arbitrary fixed sentence (YES in step S12)
S), the sentence code number is converted into an arbitrary fixed sentence by reading out the optional fixed sentence stored in the optional fixed sentence storage area 62 of the memory 6 corresponding to the sentence code number (step S14).

After completing the above-described processing for one set of identifier and sentence code number, the control unit 5 determines whether or not all sentence code numbers in the message have been processed (step S).
15) If not finished, return to step S12 and repeat the above-described processing. If the conversion has been completed, a message in which one or more fixed sentences and / or arbitrary fixed sentences obtained by the conversion are arranged in the conversion order is sent to the LC driving circuit 12 via the LC driving circuit 12.
It is displayed on D13 (step S16).

Next, the creation of a message when calling another receiver and the generation of a dial tone corresponding to the sentence code number will be described using the receiver shown in FIG. When calling the radio selective call receiver, dial the subscriber number from the touch phone, and then enter the sentence code number corresponding to the message you want to send along with the identifier,
Normally, the sentence code number or identifier is sent as a dial sound signal to the control device on the side of the radio selective calling transmitter when the user presses the push-phone button. The radio selective calling receiver of the embodiment shown in FIG. 2 can automatically generate such a dial tone signal. Hereinafter, the operation will be described with reference to FIG.

First, the user operates the keyboard 7 to set the receiver to the message creation mode (step S2).
1). Next, the user operates the keyboard 7 to quote the fixed phrase stored in the fixed phrase storage area 61 of the memory 6.
Alternatively, it is selected whether to cite an arbitrary fixed phrase stored in the arbitrary fixed phrase storage area 62 (step S22).

When a reference to a fixed phrase is selected (NO in step S22), the control unit 5 of the receiver takes in the contents of the fixed phrase storage area 61 of the memory 6 into the control unit 5, and
A list of fixed phrases is displayed on the LCD 13 via the D drive circuit 12 (step S23). On the other hand, if the quotation of the arbitrary fixed phrase is selected (YES in step S22), the contents of the arbitrary fixed phrase storage area 62 of the memory 6 are taken into the control unit 5, and the arbitrary fixed phrase is stored in the LCD 13 via the LCD drive circuit 12. A list is displayed (step S24).

Next, when the user selects a fixed form sentence or arbitrary fixed form sentence from the list displayed on the LCD 13 by operating the keyboard 7, the control unit 5 determines the selected fixed form sentence or arbitrary fixed form sentence. Then, the determined contents are accumulated (step S25). Then, it is determined whether the quotation continuation is instructed or the termination is instructed from the keyboard 7 (step S26). If the quotation continuation is instructed (NO in step S26), the process returns to step S22 to perform the above-described operation. repeat.

If the end of the quotation is instructed (YES in step S26), the control unit 5 stores the sentence code numbers corresponding to the quotations determined so far in the fixed sentence storage area 61 of the memory 6 in the quotation order, in the arbitrary fixed form. By reading from the sentence storage area 62 and adding a code number corresponding to an identifier for identifying a fixed sentence or an arbitrary fixed sentence to the head of each sentence, a sequence of code numbers corresponding to the message to be transmitted is generated (step S27). ). Then, by adding the generated code number sequence to the dial sound signal generation unit 14, the dial sound signal generation unit 14 generates a dial sound signal corresponding to the code number sequence. This dial sound signal is applied to the speaker 11 through the speaker drive circuit 10, and a dial sound corresponding to the code number sequence is generated from the speaker 11 (step S28). Therefore, if this dial sound is input from a telephone transmitter, a code number can be input.

[0025]

According to the radio receiving apparatus of the present invention described above, the following effects can be obtained.

(A) Since an arbitrary character string can be registered in the storage unit in correspondence with the sentence code number, there is almost no limit to the contents of the message which can be notified to the receiver carrier by inputting the sentence code number.

(B) A character string frequently used between a specific caller and a specific receiver carrier is registered in a storage unit in correspondence with a certain sentence code number. Thereafter, the character string can be transmitted simply by sending the sentence code number. Therefore, it is not necessary for the caller to convert each character constituting the message one by one into a code number and input the code number from a touch phone or the like every time as in the related art, and the number of input codes is reduced. Input errors are reduced. Also, sufficient contents can be transmitted within the number of code numbers that can be input for one call.

(C) A message to be transmitted can be assembled on the display by referring to a character string registered in the storage unit, and converted into a sentence code number according to the content and the sentence code can be converted. Since the generation of a dial tone according to the number can be performed automatically, it is possible to check the transmitted message in advance, and it is possible to eliminate errors in inputting the necessary sentence code number at the time of calling.
