Problems solved by technology

[0007] The problem in Japanese Patent Application Laid-Open No. 244065 / 1993 is that a large amount of information must be pre-entered into RAM so that many different types of errors can be corrected
In this case it is not possible to correct the erroneous part of the message in the main storage
[0010] Moreover, the above conventional systems only correct errors that occur in communication routing, and no system corrects errors due to incorrect input by the caller
For example, when a caller forgets to enter a character conversion code or confuses data entry, correct character conversion cannot be performed

no. 2 example

[0077] A second embodiment of the present invention is described below with reference to FIG. 4, which is a block diagram of the CPU 6 in the receiver. In FIG. 4, the same components as the CPU 6 shown in FIG. 2 are given the same reference numerals for easy understanding.

[0078] The key difference between the first embodiment and the second embodiment is that the wireless selective calling receiver of the second embodiment is equipped with a second search unit 31 for searching the part where characters repeat, instead of the first search unit 30, The first search unit 30 is used to find whether the number of characters after the character conversion code shown in FIG. 2 is odd or even.

[0079] Therefore, the second search unit 31 searches for repeated characters. Heavy characters do not indicate the presence of characters, but only a high probability of error. Such errors are typically caused by incorrect input by the user (eg, consecutive characters caused by the user p...

[0091] A third embodiment of the present invention is described below with reference to FIG. 6, which shows a block diagram of a CPU 6 in a receiver of the third embodiment, particularly in a radio selective calling receiver such as a pocket pager.

[0092] In FIG. 6, the same components as those of the CPU 6 shown in FIGS. 2 and 4 are assigned the same reference numerals. The wireless selective calling receiver of the third embodiment is equipped with a first search unit 30 and a second search unit 31, and the first search unit 30 is used to find whether the number of characters behind the character conversion code is odd or even (for example, as shown in Figure 2 shown), the second search unit 31 is used to search for the continuous part (for example, repeated part) of the same character, as shown in FIG. 4 .

[0093] The operation of the radio selective calling receiver shown in FIG. 6 will be described below with reference to the flow charts in FIGS. 7 and 8. FIG. 7 and 8...

[0104] The receiver of the fourth embodiment of the present invention will be described below with reference to FIG. 9 showing a block diagram of the CPU 6 in the receiver of this embodiment, particularly in a radio selective calling receiver such as a pocket pager.

[0105] In FIG. 9, the same components as those of the CPU 6 shown in FIG. 6 have the same reference numerals to facilitate understanding. The CPU 6 of the radio selective calling receiver of the fourth embodiment has a structure in which the CPU 6 of the radio selective calling receiver shown in FIG. For example, matrix characters such as kana characters or other predetermined language characters found in the matrix) without deleting a character after performing the operations of the first lookup unit 30 and the second lookup unit 31 .

[0106] Also, the character conversion section 28 converts the characters in the character string into characters of a predetermined language (for example, kana characters) one by...

Abstract

A method and receiver for correcting a received message includes a character converter for converting received data into a character string, and for converting character string into characters, when a predetermined character in the character string is recognized by the character converter. A message converter corrects a message formed by the character when an error is included in the message.

Description

technical field [0001] The present invention relates to methods and devices for message correction, and in particular to receivers and methods for correcting received message information. Background technique [0002] When sending predetermined language characters (for example, may be kana characters (Japanese language characters) or similar matrix characters) as message information to the receiver, the caller inputs the character conversion code of the character (for example, kana characters) and then enters the corresponding The numeric data for this particular kana character in order to send this character. According to the character conversion matrix shown in Fig. 15, one two-digit character is used for one character. When there is a character conversion code in the received message, the receiver converts the digital data into characters according to the character conversion matrix, and displays the message information in the character form on the display portion.
