Specific embodiment
The present invention provides a kind of method, system and mobile terminal that short message encoding scope is arranged based on national code, to make this
The purpose of invention, technical scheme and effect are clearer, clear and definite, and the present invention is described in more detail below.It should be appreciated that this
The described specific embodiment in place is not intended to limit the present invention only to explain the present invention.
127 characters, and 1 escape are contained in 7 bit Default Alphabet of GSM in 3GPP agreements.
Wherein, 0x1B is used for the character being introduced in 7 bit default alphabet extension table of GSM, if existed
Occurs 0x1B in message content, then, equivalent to latter character of escape, latter character is according to 7 bit of GSM for the character
Definition in default alphabet extension table is any character to determine.Generally, when user moves
Dynamic terminal（Such as mobile phone）During middle input English note, system can use this coded system, and so, a short message content is at most
160 English characters can be included.
And in the evolution of technology, 3GPP 23.038 expanded Single shift mechanism and
Locking shift mechanism mechanism.Single shift mechanism are to replace " 7 bit default of GSM
A kind of mechanism of alphabet extension table ", that is, occur 0x1B in message content, character thereafter not basis
" 7 bit default alphabet extension table of GSM " parsing, but according to header in User Data
The table that part indicates is parsing.The corresponding form collection of Single shift mechanism mechanism is combined into " National
Language Single Shift Tables ", abbreviated here as GSM7 extended coding substitution table set.
Locking shift mechanism are a kind of mechanism for replacing " 7 bit Default Alphabet of GSM ",
Namely the 7bit characters in message content do not use " 7 bit Default Alphabet of GSM ", but according to User
The table that header parts indicate in Data is parsing.The corresponding form collection of Locking shift mechanism mechanism is combined into "
National Language Locking Shift Tables ", abbreviated here as GSM7 default coding substitution table set.
Such as in Turkey, it is assumed that occur in the character of user input more " Turkish National Language
In Locking Shift Table " forms, rather than " 7 bit Default Alphabet of GSM " in, then, so that it may so that
With " Turkish National Language Locking Shift Table " replacing " 7 bit Default of GSM
Alphabet ", takes more channel resources in the transmission to reduce user inputs character.It is because if not replacing, then necessary
Switch to UCS2 codings, UCS2 encodes a character and takes 2 bytes, and " 7 bit Default Alphabet of GSM " and "
Character of Turkish National Language Locking Shift Table " only takes up 7 bits.
In short message encoding, the table in an essential base table set, the table in an optional expansion table set.General meeting
The default coding schedules of prioritizing selection GSM7 and GSM7 extended coding tables.And if the character of user input is beyond the default codings of GSM7
The scope of table and GSM7 extended coding tables, then need from mobile terminal（Such as mobile phone）Upper preset GSM7 is default to encode substitution table collection
Close and the set of GSM7 extended coding substitution tables obtains optimum combination, it is most in data is activation with the process of guarantee agreement data length
Amount takes Internet resources less.What the mainstream speech that a general country uses was to determine, therefore, we can be main by the country
The code set for flowing language to confirm to support needed for the mobile terminal.
Fig. 1 is referred to, Fig. 1 is the method preferred embodiment that short message encoding scope is arranged based on national code of the present invention
Flow chart.As shown in figure 1, which comprises the following steps：
Step S100, when detect mobile terminal insertion usim card when, then from usim card read IMSI, and from IMSI extract
MCC；Wherein, the IMSI is international mobile subscriber identity（International mobile subscriber is recognized
Code）Abbreviation；The MCC is Mobile Country Code（Mobile Country Code MCC）Abbreviation.
The default coding substitution table of step S200, the GSM7 corresponding with the MCC that will prestore and GSM7 extended codings are replaced
Table pack is imported in the mobile terminal system.
Further, the combination at least 13 of the default coding substitution tables of the GSM7 and GSM7 extended coding substitution tables.
So far, base table has 12 kinds can replace " 7 bit Default Alphabet of GSM " table, expansion table have 13 kinds can be with
Replace " 7 bit default alphabet extension table of GSM " table, therefore, the default codings of the GSM7 is replaced
The combination of table and GSM7 extended coding substitution tables at least 13.As shown in table 1, the base table is corresponded with expansion table.
After mobile terminal-opening inserts usim card, you can according to the MCC on the usim card of insertion, determine
The default coding substitution tables of GSM7 held and the scope of GSM7 extended coding substitution tables.

In prior art, scheme of the acquiescence using mobile terminal factory pre-set, but this needs manufacturer issuing mobile terminal to certain
Before individual country, just the default coding substitution tables of GSM7 and GSM7 extended coding substitution tables according to country's suggestion support, sets
Put the default coding substitution tables of GSM7 and GSM7 extended coding substitution tables that the country need to support.If such as mobile terminal batch
Secondary shipment then need to specify support in mobile phone to Turkey:Turkish National Language Locking Shift
Table, Turkish National Language Single Shift Table；If wanting shipment to Spain, need
Specify in mobile phone and support:Spanish National Language Single Shift Table.This specified support
Code set is that manufacturer is preset before dispatching from the factory.But, in prior art, if when manufacturer's delivery is national to one, finding should
State does not reach expected shipment amount, need this part mobile phone re-send to another it is national when, it is necessary to GSM7 is lacked
The support for saving coding substitution table and GSM7 extended coding substitution tables carries out software modification.And technical scheme is caused in handss
It is not required to the support of the default coding substitution tables of GSM7 and GSM7 extended coding substitution tables is carried out for concrete certain country when machine dispatches from the factory
It is preset, but coding substitution table default with GSM7 and GSM7 extended codings are replaced in the mobile terminal system that table pack prestores,
In this manner it is possible to the default coding substitution tables of GSM7 and GSM7 extended coding substitution tables of locality is supported, so as to reduce technology, people
Power puts into the risk upgraded to mobile phone with the error probability during software modification and cell phone manufacturer again.
Further, the method for arranging short message encoding scope based on national code also comprises the following steps：When user compiles
When collecting and sending note, then obtain the default coding substitution tables of the GSM7 and GSM7 extended codings are replaced table pack and encoded.
Specifically, when all characters of the short message content that user edits are included in the default coding substitution tables of GSM7, then directly use
The default substitution tables that encode of the GSM7 are encoded；When the short message content that user edits has character to be not included in the default codings of GSM7
When in substitution table, then the default coding substitution tables of the GSM7 are replaced using the GSM7 extended codings substitution table and encoded.
Further, as shown in Fig. 2 by the GSM7 for prestoring default coding substitution table and GSM7 extensions in step S200
Coding is replaced table pack setting and is specifically included in the mobile terminal system：
Step S201, by the MCC of the MCC and support GSM7 that prestores default coding substitution table and GSM7 extended coding substitution tables
Compare, and find out the default coding substitution tables of GSM7 corresponding with the MCC and GSM7 extended codings replacement table pack；
Step S202, by it is the GSM7 for finding default coding substitution table and GSM7 extended codings replace table pack import arrange to institute
State in mobile terminal system.
In order that present disclosure becomes apparent from, it is exemplified below.
Usim card is inserted after start, when usim card is detected, is read and IMSI is therefrom extracted its MCC, by the MCC and
Prestore support GSM7 it is default coding substitution table and GSM7 extended coding substitution tables national code compare；
Such as, by taking Turkey and Brazil as an example, our first following data preset in mobile phone:
＜ mcc=' 286 ', single_shift_tables=" 1 ", locking_shift_tables=" 1 ">
＜ mcc=' 724 ', single_shift_tables=" 3 ", locking_shift_tables=" 3 ">
Wherein, mcc=' 286 ' Turkey is represented, mcc=' 724 is represented ' Brazil, and single_shift_tables represents support
GSM7 extended coding substitution tables, locking_shift_tables represents the default coding substitution tables of the GSM7 of support.single_
Shift_tables and locking_shift_tables numerology below is following, and (3GPP 23.038 has corresponding relation, root
According to the renewal of 23.038 later releases of 3GPP, the digital number should may proceed to increase): 0 - reserved
1 - Turkish
2 - Spanish (single shift table only)
3 - Portuguese
4 - Bengali
5 - Gujarati
6 - Hindi
7 - Kannada
8 - Malayalam
9 - Oriya
10 - Punjabi
11 - Tamil
12 - Telugu
13 - Urdu
Then, coding substitution table default with national code identical GSM7 and GSM7 extended coding substitution tables are found.
If mcc=' 286 ', then it represents that for Turkey, and single_shift_tables=here " 1 " and locking_
Shift_tables=" 1 ", then it represents that support Turkish National Language single Shift Table and
Turkish National Language Locking Shift Table。
Finally, the GSM7 for finding default coding substitution table and GSM7 extended codings are replaced into table pack and system is set to
In.
As Turkish National Language single Shift Table and Turkish National
The support of Language Locking Shift Table is arranged in system, when user edits and sends note, then can be with
Encoded using the two forms.
For how two forms are replaced, have for an example for using scene here, such as sell to osmanli mobile whole
End（Such as mobile phone）, when the short message content that user edits is：During abcdefgh, then these characters are included in 7 bit of GSM
In Default Alphabet, then directly using the form；But, when the short message content that user edits is：
abcdefghWhen, in the GSM7bitDefault Alphabet and not comprising the two characters, now, if institute
State mobile terminal（Such as mobile phone）Turkish National Language Locking Shift Table are supported, and supports to make
The form is used, then due to abcdefghAll of character is all in the form, then now system is just automatically by Turkish
National Language Locking Shift Table replacing 7 bit Default Alphabet forms of GSM, with
Guarantee the protocol data length used by the character being input into, so as to take Internet resources in data is activation less as far as possible.If institute
State mobile terminal（Such as mobile phone）Turkish National Language Locking Shift Table are not supported, then just
Must be with UCS2 come coded string abcdefgh, and in UCS2, each character takes 2 bytes, considerably increases shared
Internet resources.
