DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiver, and more particularly, to a selective call receiver having a tone dialer function and facilitating a message transmission operation.

[0002]

2. Description of the Related Art In recent years, a selective call receiver having a tone dialer function has become widespread as multi-functions of a selective call receiver have been developed. This tone dialer function means that information such as telephone numbers registered in advance is stored in a DTMF (Dual Tone Multi-
Frequency) signal and output a tone from a speaker or the like to make a call without having to operate the dial of the telephone. Recently, it is also used to transmit a message to a selective call receiver. .

When a message is transmitted to a selective call receiver using the tone dialer function, DTMF-compatible numbers and symbols that can be input from a telephone are only numbers “0” to “9” and “*” and “ However, recently, a transmission message (hereinafter, referred to as an original message) consisting of “Katakana”, “Alphabet”, “Numerical”, and “Symbol” is DTMF-compliant according to a predetermined conversion table. The original message is converted into two-digit numbers and symbols (hereinafter referred to as an encoded message) and transmitted, and the encoded message is inversely transformed by the above-mentioned conversion table on the receiving side. Can be displayed on the screen.

[0004] In addition, the selective call receiver uses a control code added to the beginning or end of the coded message to automatically convert the received coded message into an original message, and a user operates a predetermined switch. And the relationship between the characters and the corresponding two-digit numbers and symbols is slightly different. Therefore, when a message is transmitted to the selective calling receiver using the tone dialer function, the original message is converted into a conversion table corresponding to the transmission destination by designating the function of the selective calling receiver of the transmission destination and the type of the conversion table. Automatically converted to an encoded message and transmitted based on the message.

[0005]

However, the conventional tone dialer function has the following disadvantages. For example, in the case where a pre-specified original text message "5 Japanese pine tree" is transmitted as a message to a selective call receiver of a type that is converted to an encoded message by a switch operation on the receiving side, the code of the above example is used. Message is "5032045221314"
55142224404143 # ", and the number of digits of the transmitted message is 26 digits (the last ## is not counted in the number of message digits).

When a message is transmitted as a message to a selective call receiver of a type that automatically performs conversion, the encoded message in the above-mentioned example is "* 2 * 29032205213".
1455422244041433 ## ",
The number of digits of the transmission message is 28 digits (* 2 is counted as one digit as the number of digits of the transmission message).

However, in the current system, the maximum number of digits of an encoded message that can be accepted at one time is limited, and the limit also differs depending on the system of the selective call receiver of the transmission destination. For example, if the maximum number of digits is limited to 24 digits, the message of the above-described example will not accept 25 digits or less. In such a case, when the message exceeds the maximum number of digits, it is normal for the system to output voice guidance to that effect.However, if the message is transmitted using the tone dialer function, the receiver will be turned off. In many cases, the message is not heard, and if the user misses the guidance, the sender determines that the message was accepted even though the message was not accepted correctly, and the intended message was sent to the other party. Sometimes not communicated. Of course, if the carrier correctly calculates the number of digits of the encoded message each time, such an error can be prevented. Since the number of digits of the coded message is different, it is very troublesome and easy for the carrier to calculate the number of digits of the coded message after the conversion by himself.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and when a carrier transmits a message to a selective call receiver, the number of message digits is restricted by the maximum number of message digits of the system. It is an object of the present invention to provide a selective call receiver with a tone dialer function which is excellent in operability by eliminating the trouble of calculation.

[0009]

SUMMARY OF THE INVENTION To achieve the above object, a selective calling receiver with a tone dialer function of the present invention automatically calculates the number of digits of a message to be transmitted by a predetermined switch operation and displays the number on a display unit. It is characterized by comprising means for performing.
