Abstract

In a device such as a portable data terminal, characters are received in a format (e.g. Unicode) which can represent at least two different character sets for representing similar characters, such as Traditional and Simplified Chinese. The received characters are converted into a format (e.g. GB code) in which equivalent characters from the two character sets have the same code. The converted codes are then converted into displayed characters in a font which represents a preferred one of the character sets.

Description

Character display technique

The present invention relates to a kind of method and apparatus, the character intercropping that receive and that show that is used in a message is changed, preferably but be not used for a high hand, and preferably but be not used for a portable data terminals machine with a high hand if any the limited memory capacity of the mobile phone of text capabilities in simplified and traditional Chinese character intercropping conversion.

Bimillennium in past, many Chinese characters remained unchanged; Yet in the China's Mainland, many characters are improved read-write by simplified; Singapore and Malaysia follow simplified character set, and traditional Chinese character is still used in Taiwan and Hong Kong; Therefore, even between most these two character set a man-to-man correspondence is arranged, and pronunciation is identical with the syntax, and the text message between these countries may not be understood mutually.

In the Unicode standard, according to its written form and regardless of its meaning, 20,902 designated two different byte values of Chinese character; Not too economical in a portable electron device the complete font data library storage of all these characters; Substitute, according to user's zone, the font data storehouse of a subclass is stored usually; Therefore, if simplified Chinese character is not received person's mobile phone support then can't correctly shows from Chinese SMS (Short Message Service) message of delivering to Taiwan at a cell phone of China's Mainland; Even simplified character is supported, the recipient does not still understand them.

According to the present invention, provide a kind of method to come on a terminating machine, to show a character of receiving, comprise the character of reception from first character set; Judge whether each character falls within second character set of having only with common some characters of this first character set; And if any character do not fall in this second character set, then this character conversion to the corresponding character in this second character set, and show the character of deriving from the character of receiving.

Preferably, this first and second character set is respectively simplified and traditional Chinese, or vice versa.

Character can receive by the Unicode form, and uses the form that a look-up table converts a coding of replacing to; The form of the coding of this replacement can be used the yi word pattern database corresponding with this second character set and change with character display.

The simple description of accompanying drawing

Fig. 1 is a front view of mobile phone handsets;

Fig. 2 is a figure of the internal electrical components of mobile phone;

Fig. 3 shows and to be stored in the structure that allows the database on the mobile phone H that Chinese character is shown;

Fig. 4 is used for being presented at a flow chart of the deduction rule of the character in the preferable character set of user.

Fig. 1 shows to have the numerical key of comprising 0 to 9, star ( ^*) and hash (#) key, and such as " YES ", " NO ", retreat (←), forward (→), remove the mobile phone handsets H of a keyboard K of the function key of (CLR) and other functions (f); One display D can show Arabic numerals, Roman capitals and Chinese characters, and can be to have abundant resolution to show numeral, a LCD of at least one line of font and character; One microphone M and loudspeaker S also put forward to allow tone calling.

Fig. 2 is a structure chart of the electronic building brick of mobile phone H; These assemblies need not separate, and can be integrated; For example, assembly can be integrated on a microcontroller chip and the RF level section chip; One processor P is connected to a volatile memory (V), a nonvolatile memory (NV), an I/O interface (I/O) and a RF modulator-demodulator (RF) via a bus B; The I/O interface is from the input of keyboard K and microphone M decoding, driving display D and loudspeaker S, and allow data to import partly via infrared port (IR) and transmit; Infrared port (IR) allows title, telephone number and other data and other local device as kneetop computer or PDA to exchange; Nonvolatile memory (NV) can comprise the SIM card of storage as user's customization data of address-book data, and can be transferred to another mobile phone H; The RF modulator-demodulator is connected to an antenna A and receives and transmit the RF signal; Assembly is electrically connected (not shown) via a transformer by a battery (not shown) or a master and supplies electric power.

Nonvolatile memory (NV) storing software, it is carried out to implement the function of mobile phone by processor P; Can accept or reject ground, nonvolatile memory can plan upgrade software again; The deduction rule that is described in down as one embodiment of the invention can be mounted the upgrading of conduct to the software of an existing mobile phone; Upgrading can receive as a wireless type message via RF modulator-demodulator (RF).

Mobile phone H implements the agreement that the permission text message is sent and receives; For example, mobile phone can be the GSM compatibility and supports GSM SMS (Short Message Service) agreement; The form of the not specific SMS message of SMS agreement, and reference format is used for determining spreading out of and receive the compatibility between terminal; One of the most frequently used is Unicode, and its pattern 3.0 is supported to comprise in the most widely used document of different language of simplified and traditional Chinese and is close to 50,000 characters.

As being described in down with reference to figure 3 and 4, cell phone software has ability and receives and the Chinese display character; They are stored among the first and second look-up table T1 and T2 of nonvolatile memory (NV); The first table T1 has and is used for the preferable character set the user, and is simplified or traditional, respectively is tied to a unified code table of the Chinese character of a corresponding GB sign indicating number.

Two bytecodes of GB sign indicating number for being defined by a Chinese national standard; Identical GB sign indicating number is represented a traditional Chinese character and its simplified equal person.

The second table T2 has and is used for the not preferable character set the user, and is simplified or traditional, respectively is tied to a unified code table of the Chinese character of a corresponding GB sign indicating number; The software that operates on mobile phone is taken each Unicode character (S10) of receiving in turn and is searched for the first table T1 and judge whether this Unicode character (S20) occur; If then software is shown the value (S30) that T1 returns corresponding GB sign indicating number from first

If Unicode does not appear among the first table T1, then the software search second table T2 judges whether the Unicode character appears at there (S40); If then software is return corresponding GB sign indicating number (S50) from the second table T2.

A string Unicode character that so, be shown is converted into a string GB sign indicating number earlier.

Also be stored in the only yi word pattern table F of the Chinese character data in the preferable character set that indicates with the GB sign indicating number that has among the nonvolatile memory NV; Software is fetched video data (S60) from being used for respectively going here and there the font table F of GB sign indicating number then, and video data is exported to display D (S80); But the font table can be stored a bitmap of each character display.

In order to make character and the numeral that mobile phone can Chinese display, can provide the more xi-type table that is for example indicated by Unicode, ASC II or a proprietary internal code; If the Unicode character that does not occur receiving among the T2 at table T1 or table then software can be searched for this more font table, and so fetch appropriate display data (S70).

So, mobile phone H only need store the video data of the character that is used for the preferable character set of user, and the data of receiving are converted to the preferable character set that is used to show automatically.

According to the zone that mobile phone is wherein peddled, the content of the first and second font table T1 and T2 and font table F can be planned in the NV in factory or by the dealer; Alternatively, content can be crossed Radio Link or be downloaded and plan to nonvolatile memory (NV) by infrared port IR; The first and second table T1 need not to different with T2; Replace ground, they can be combined into single table; Only require to obtain correct GB sign indicating number, and font table F is tied to the GB sign indicating number of the character of receiving the appearance of the character in preferable character set.

Replacement GB sign indicating number, another standard or private code can be used in the character that is converted to demonstration; For example, the Unicode of receiving can be converted into the address code of pointing out the address of the video data of equal character in font table F.

When entirely true, several simplified Chinese characters that have more than a suitable traditional form are arranged to being converted between simplified Chinese when traditional, make that converting traditional Chinese to from Unicode can't correctly be finished by said method; Yet the form of Xian Shiing can be easy to understand in most cases.

Preferably, the character of receiving comes storage inside with the Unicode form, but is converted to GB sign indicating number and therefore only video data just when they will be shown; Character can be received as a SMS message or be data via infrared port IR or from a SIM; For example, the user may wish an address book that is stored on the SIM is transferred to different mobile phones of supporting Chinese character; Name in address book shows with preferable character set then automatically.
