Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of client identification card storage, read technology.
Background technology
In the prior art; The application software of main frame adopts GSM7 and UCS280 coding method needs to be stored in SIM (the Subscriber Identity Module of the portable terminal that links to each other with main frame usually; Client identification card) data such as name in the telephone directory are encoded; Then coded data and store instruction are sent to the terminal, portable terminal is stored in coded data in the SIM according to store instruction.GSM7 coding mainly is to change West Europe language such as English and spcial character that some is commonly used into 8 binary representations, takies the code word in a bytes of memory space; The UCS280 coding is with the regulation of each character according to ISO/IEC10646, changes 16 binary representations into, takies the code word in two bytes of memory spaces.Because the literal that many countries use can not be that the GSM7 coding that 8 bits are represented carries out character code with only taking a byte; For example: the SIM phone directory is because of the restriction of hardware, and each field of phone directory all has the restriction of length, and particularly " name " field is generally all shorter, and memory space is little.Suppose that " name " field stores 16 bytes at most, if adopt the GSM7 coding English, this field can be stored 16 letters at most; If adopt the UCS280 coding, then because the coding of a Chinese character need take two bytes, so this field is stored 8 Chinese characters at most; And in fact,, have a message header that takies two bytes in this field because adopt UCS2 to encode when carrying out the storage of " name " field, like this, this field reality can only be stored 7 Chinese characters at most.For the storage of described Chinese " name " field, this restriction is also more acceptant.But,,,, tens characters are arranged all generally because Russian's name is generally all long such as Muscovite Cyrillic literary composition for some languages.Like this, because hardware constraints that should " name " field, if carry out this Russian's of storage that the storage of " name " field just can't be complete name according to the UCS280 coding.
In realizing process of the present invention; The inventor finds following at least problem: except the West Europe Latin language can be set to a byte code of GSM7 coded format; Other Languages uses the coding of two bytes of UCS280 coding; So if SIM name field length restriction is " n " individual byte, " n/2 " individual word stored at most in language such as storage Chinese or Russian so.

Embodiment
In order to solve in the prior art; Input character is that other language beyond the Latin language such as West Europe are only supported in the UCS2 coding UCS2 80 coded formats to carry out code storage to cause the big problem of memory space that takies; Adopt the embodiment of the invention can be set to the byte code of GSM7 coded format except common Latin languages such as West Europe; Other Languages not only can be selected UCS2 80 codings for use according to the needs of actual input character, can also select for use to take less UCS2 81 codings of memory space and UCS2 82 codings.UCS2 81 has significantly reduced the memory space of data such as name in SIM with the appearance of UCS2 82 coded systems.
At first introduce the UCS2 coding principle below so that the clearer understanding of those skilled in the art technical scheme of the present invention.Usually; The name that is stored in the SIM telephone directory adopts three kinds of UCS2 coded formats: first kind of UCS2 80 coding generally is used for pure English; Second kind of UCS2 81 coding encoded with the third UCS2 82 and generally is used for the situation of non-English; Its main difference is that the interval range of all characters of UCS2 81 coding requirements in the UCS2 coding is no more than 127, and 82 codings are unrestricted.Introduce one by one below.
But the first clock UCS2,80 coded system reference tables one; First Byte 1 of data be character string ' 80 '; Ensuing Byte s (eight bit byte) is 16 bits UCS2 characters; Numbering is the MSB (high byte) of UCS2 character in preceding byte, the numbering after be the LSB (low byte) of UCS2 character.For example second Byte comprised the MSB of first UCS2 character, and the 3rd Byte comprised the LSB of first UCS2 character, and the Byte that does not use then is changed to ' FF '.
Table 1 80 codings for example
| Byte?1 | Byte?2 | Byte?3 | Byte?4 | Byte?5 | Byte?6 | Byte?7 | Byte?8 | Byte?9 |
| ′80′ | Ch1 MSB | Ch1 LSB | Ch2 MSB | Ch2 LSB | Ch3 MSB | Ch3 LSB | ′FF′ | ′FF′ |
Under this kind coding, if SIM maximum storage field is a n byte, the UCS2 character that then can represent is (n/2-1) to the maximum.
For example: " 80 4E 2D, 56 FD FF FF " expression " China ".
But second kind of UCS2 81 coded system reference table two, first character string is ' 81 ', ensuing Byte 2 expression character numbers, the 3rd Byte (Byte 3) is the bit 15 to bit8 of 16 basic pointers; In this basic pointer, bitl6 puts ' O ', and bit7 also is changed to ' 0 ' to bitl; The bit8 of the 4th and later Bytes is if zero, and what then the bit7 of the 4th and later Bytes represented to bitl is exactly corresponding characters in the GSM7 character list; If bit8 is l, what then the bit7 of the 4th and later Bytes represented to bitl is exactly a side-play amount of UCS2 coding, adds that with this side-play amount foregoing basic pointer just can obtain required UCS2 sign indicating number.
Table 2 81 codings for example
| Byte?1 | Byte?2 | Byte?3 | Byte?4 | Byte?5 | Byte?6 | Byte?7 | Byte?8 | Byte?9 |
| ′81′ | ′05′ | ′13′ | ′53′ | ′95′ | ′A6′ | ′XX′ | ′FF′ | ′FF′ |
Under this kind coding, if SIM maximum storage field is a n byte, the UCS2 character that then can represent is (n-3) to the maximum, but all USC2 characters can not surpass 127 from plot.This is coded in three kinds of codings and saves the space most, but 127 skew quantitative limitations are arranged, and the plot scope also has restriction, thus under Chinese DeGrain, but just advantageous in language such as Russian (Cyrillic literary composition).
For example:
Russian " И р И a Ac " adopts the Cyrillic literary composition, and 81 corresponding codings are " 810F0898C0B8BDB02090C1 ", and specific explanations is following:
81 presentation code forms are USC281;
0F representes that input character length is 15;
08 expression base address 0400;
98 presentation address are 0418, i.e. Cyrillic literary composition И;
The C0 presentation address is 0440, i.e. Cyrillic literary composition p;
The B8 presentation address is 0438, i.e. Cyrillic literary composition И;
The BD presentation address is 043D, i.e. Cyrillic literary composition H;
The B0 presentation address is 0430, i.e. Cyrillic literary composition a;
20 presentation address are 20, i.e. space, and bit7=0 is so this is the GSM7 coding;
90 presentation address are 0410, i.e. Cyrillic literary composition A;
The C1 presentation address is 0441, i.e. Cyrillic literary composition c.
But the third UCS282 coded system reference table three; First character string is ' 82 '; Ensuing second Byte comprised character number; The 3rd and the 4th Byte form 16 a complete basic pointer, if the bit8 of the 5th and later Byte is zero, what then the bit7 of the 5th and later Byte represented to bit1 is exactly corresponding characters in the GSM7 character list; If the bits8 of the 5th and later Byte is 1, then the bit7 of the 5th and later Byte to the bit1 bit representation be exactly a side-play amount of UCS2 coding, this side-play amount of usefulness adds that the basic pointer of front is exactly required UCS2 sign indicating number.
Table 3 82 codings for example
| Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 | Byte8 | Byte9 |
| ′82′ | ′05′ | ′05′ | ′30′ | ′2D′ | ′82′ | ′D3′ | ′2D′ | ′31′ |
[0099]Under this kind coding, if SIM maximum storage field is a n byte, the UCS2 character that then can represent is (n-4) to the maximum, but all USC2 characters can not surpass 127 from plot.The same with 82 codings, 81 codings also have 127 skew quantitative limitations, thus under Chinese DeGrain, but just advantageous in language such as Russian (Cyrillic civilian).
For example, the Chinese character "a Ding Yu seven
ㄒ
bottomless three"
80 coding " 4E004E014E024E034E044E054E064E074E084E09 " (continuous)
81 coding " 0A9C80818283848586878889 " (continuous)
82 coding " 0A4E0080818283848586878889 " (continuous)
Three kinds of its contrasts of coding are summed up as shown in table 4 in sum;
Three kinds of codings of table 4 contrast table
| ? | 80 codings | 81 codings | 82 codings |
| Form | 80 CH1msbCH11sbCH2msbCH21sb… | 81 length (1 byte) plots (1 byte) data (each data 1 byte) | 82 length (1 byte) plots (2 byte) data (each data 1 byte) |
| Can support maximum UCS2 number of characters, suppose the maximum n of support of SIM byte | n/2-1 ? | n-3 | n-4 |
| The UCS2 character content restriction of codified | Do not have | 1) each UCS2 character and plot deviation are not more than 127; 2) plot is a byte, and expression is limited in scope | Each UCS2 character and plot deviation are not more than 127 |
From three kinds of codings of top USC2 were introduced, in the prior art, the standard AT command of 3GPP had only used USC2 80 codings, a kind of coding that space utilization efficient just is minimum.
The embodiment of the invention is exactly through expansion AT command, lets " management software that TE2 is last " and " software that MT2 is last " can both support three kinds of codings of UCS2, thereby reaches the purpose of the most efficiently utilizing the SIM data space.Wherein, said TE2 can be portable machine, desktop computer; Operation wireless data card management software, perhaps " mobile phone synchronizing software " above, back literary composition general designation " management software that TE2 is last "; MT2 can be wireless data card, wireless Modem, mobile phone.
Wherein, expand two AT orders:
^CPBR, the command format that reads phone directory is:
^CPBR: < indexl >, < number >, < type >, < text >, < coding >; Wherein,
< index1>is the integer value, the position in the expression phone directory internal memory;
< number>character string type, telephone number;
< type>type of number;
< text>character string type, the expression name;
< coding>encoding scheme, the character code and the appointed language of expression < text>field, promptly last parameter < coding>can the presentation code pattern: 0 expression " GSM7 coding " only is used for the common Latin alphabets such as West Europe that 3GPP defines; 1 expression " three kinds of coded formats of UCS2 ".
^CPBW, the command format of writing phone directory is:
^CPBW: [< index >] [, < number>[, < type>[, < text >, < coding>[, email]]]]; Wherein, < index>is the integer value, the position in the expression phone directory internal memory;
< number>is telephone number, and its character string type comprises: ' 0-9 ', ' # ', ' * ', '+', ' (', ') ', '-'); Wherein, ' (', ') no matter ', '-' three character appear at any position, and handling procedure is all ignored them, can not report an error as forbidden character.
< type>is the type of number, wherein 145 expression international numbers;
< text>is character string type, expression name (not supporting carriage return, quotation marks character).
< coding>is encoding scheme, the character code and the appointed language of expression < text>field; Be that last parameter < coding>can the presentation code pattern: 0 expression " GSM7 coding " only is used for the common Latin alphabets such as West Europe that 3GPP defines; 1 expression " three kinds of coded formats of UCS2 ".
< email>character string type, expression email address.At present, this field is only effective when storage medium is usim card.
In writing the processing procedure of phone directory, according to user's input character, can judge dynamically that current which kind of coding is optimum, priority orders can be:
GSM7→UCS2?81→UCS2?82→UCS2?80
According to different coding, should point out whether overlength of character that the user writes on the pc client interface.Wherein, according to the character of said input, selecting coded format is GSM7 or UCS2 80; Further; Adopt UCS2 81 codings still to adopt UCS2 82 codings can pass through all UCS2 80 characters of traversal; As plot, other UCS2 80 characters calculate deviant, if deviant is in 127 minimum one of numerical value in UCS2 80 characters; Just can use UCS2 81 or 82 codings, otherwise can only use UCS2 80 codings.And according to the numerical value of plot, can further determine with 81 or 82 codings, if the minimum value of promptly described UCS2 80 characters in the represented scope of byte, selects UCS2 81 to encode; If the minimum value of described UCS2 80 characters in the represented scope of two bytes, selects UCS2 82 to encode.
For example:
AT^CPBR=1,50; (this order can send to the order of portable terminal for PC) is for reading 1 to 50 information of phone directory;
＾CPBR：1，＂9897867576567＂，129，＂810F0898C0B8BDB02090C1FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF＂，1
Mentioned order is: read phone directory article one information, telephone number is 9897867576567, and name is " И р И H a Ac "; Wherein, ^CPBR reads the phone directory order; The position that the information of phone directory is read in 1 expression of closelying follow thereafter; The telephone number that ＂ 9897867576567 ＂ read; 129 expressions " telephone number "; ＂ 810F0898C0B8BDB02090C1FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF ＂ representes character string type, i.e. name; Last parameter 1 presentation code scheme.
＾CPBR：2，＂78916783164987163487634＂，129，＂80044D043A0441043F043B0443043004420430044604380438FF＂，1
Mentioned order is: read phone directory second information;
