The starting procedure figure of mobile terminal is illustrated in figure 5, is comprised the following steps：
Step 51：Mobile terminal-opening, uploads the IMEI of SIM card（International MobileEquipment
Identity, International Mobile Equipment Identity code）And the version of mobile terminal is to the background system of mobile terminal, such as DM systems；
Step 52：Judge background system whether be stored with mobile terminal Modem ability information, if so, turn to step
53；If it is not, turning to step 54., can be in API because Modem module version is numerous, it is impossible to be managed in the terminal
（Application Programming Interface, application programming interface）Middle extension Modem ability acquisition modules are borrowed
Background system is helped, Modem ability is obtained；
Step 53:Modem abilities acquisition module obtains Modem ability information, and this movement is judged according to the ability information
Whether the Modem of terminal has the ability directly to use the Open MobileAPI modules of standard, if so, then standard Open Mobile
API module need not do any change, can directly invoke AT instructions and be communicated with Modem；If Modem is not supported or indefinite branch
Open MobileAPI mechanism is held, then needs notice standard Open Mobile API modules to need to encapsulate by transparent transmission APDU
Module turns to step 54 to Modem transmission APDU instructions；
Step 54：The APDU that what all clients were issued interact with SIM card is instructed by standard OpenMobile API
Module is accepted, therefore it is using standard API processing modes or extension to need in start to configure the module to determine
Transparent transmission mode.Modem do not support or indefinite support OpenMobile API mechanism when, it is necessary to notify standard Open
The encapsulation and response that Mobile API modules need to carry out APDU by transparent transmission APDU modules are parsed；
Step 55：SIM card IMSI is obtained, by transparent transmission APDU acquisition modules, the corresponding transparent transmission APDU ginsengs of the SIM card are obtained
Numerical value, transparent transmission APDU parameter values include the CLS that can pass through Modem APDU instructions（Classification byte）And INS（Command byte）'s
Value, both together decides on the type of message of machine card interface.Current embodiment require that for transparent transmission APDU package modules configuration CLS and
APDU can be instructed and is encapsulated as the APDU for being capable of transparent transmission instructions by INS, such transparent transmission APDU package modules according to CLS and INS；
Step 56：Judge whether to obtain in transparent transmission APDU parameter values, the step and to be looked into by transparent transmission APDU acquisition modules
Ask whether SIM card has variation, whether can obtain above successfully transparent transmission APDU parameter values, if so, turning to step 57；If it is not,
Turn to step 58；
Step 57：CLS, INS of the transparent transmission instruction of previous Successful transmissions are obtained, and notifies transparent transmission APDU wind revolving die blocks to make
With.
Step 58：Call transparent transmission APDU negotiation modules to obtain CLS, INS of the transparent transmission instruction that can be used, and notify transparent transmission
APDU wind revolving die blocks are used.
Because the APDU transmitted in logical channel is instructed for all trades and professions, each industry defines also phase not to the utmost to APDU
Together, instructed it is difficult to define fixed CLS, an INS for transparent transmission APDU, it is therefore desirable to which a set of negotiation mechanism is dynamically found out
Modem and SIM card Applet can be passed through at present（Applet）Transparent transmission APDU instruction CLS, INS, as shown in fig. 6,
The negotiations process comprises the following steps：
Possible transparent transmission in the Modem logical channels is obtained from background system by Modem abilities acquisition module first
CLS, INS recommendation list.When forming CLS, INS recommendation list, it is necessary to by the strength of platform side, remove sector application obvious
APDU, the APDU of specific Modem products refusal CLS, the INS used, CLS, the INS for forming a transparent transmission APDU recommend
List.In each consult, by Modem ability acquisition modules background system can be gone to obtain this recommendation list, this recommendation
The content of list can change with deepening continuously for sector application.
Transparent transmission APDU acquisition modules select to plan to transmit CLS, the INS used from CLS, INS recommendation list, utilize selection
CLS, INS build transparent transmission APDU as instruction head and consult sign on, in the instruction, P1P2 is default particular value, Len=
0, transparent transmission APDU negotiations sign on is sent to SIM card afterwards.
If there is Applet to recognize that transparent transmission APDU consults sign in SIM card, define and return according to Applet；Such as
There is no Applet to recognize that transparent transmission APDU consults sign in fruit SIM card, then pass at transparent transmission APDU modules
Reason, because now transparent transmission APDU negotiations sign on has been able to normally pass through Modem, therefore transparent transmission APDU modules can be recorded
One state and the return code for returning to the non-9XXX/6XXX defined in an ETSI102.221 at random（This is able to success
Transparent transmission crosses Modem）.
Mobile terminal is received after the return code, and return code is inserted into P1P2, is continued to use a transparent transmission APDU and is consulted to start
CLS, INS in instruction, which are built, confirms APDU instructions, and will confirm that APDU instructions are sent to SIM card.
If there is Applet to recognize that confirmation APDU is instructed in SIM card, error code is returned；If do not had in SIM card
Applet recognizes that confirmation APDU is instructed, then passes to transparent transmission APDU modules and handled, transparent transmission APDU modules can be entered after receiving
Row is compared, if CLS, INS of confirmation APDU instructions consult CLS, INS mono- in sign on a upper transparent transmission APDU
Cause, and this P1P2 value confirmed in APDU instructions is the return code of last time, it is determined that CLS, the INS are instructed as APDU transparent transmissions
Modem and SIM card Applet can be passed through, can subsequently be used, 9000 mobile terminals are returned.
If the return value that mobile terminal is received is 9000, illustrate that CLS, INS for currently selecting can be used in transparent transmission
APDU is instructed；If the return value that mobile terminal is received is not 9000, mobile terminal need repeat the above steps, from CLS,
CLS, the INS for planning to transmit and using are reselected in INS recommendation lists.
After acquisition can be used in CLS, INS of transparent transmission APDU instructions, you can realize logical between client and SIM card
Letter, as shown in fig. 7, the data transmission method of the present invention specifically includes following steps：
Step 701:Client call standard Open Mobile API modules transmit data, all clients to SIM card
The APDU interacted with SIM card the instructions issued are accepted by standard Open Mobile API modules；
Step 702：Judge whether to need to call transparent transmission APDU modules to carry out data transmission, if so, turning to step 704；If
It is no, turn to step 703；
By mobile terminal-opening when may decide that it is to use standard API to the configurations of standard Open Mobile API modules
The transparent transmission mode that processing mode still extends.If the module be configured to use standard API processing modes, turn to step
703；If using the transparent transmission mode of extension, turning to step 704；
Step 703：Notice standard Open Mobile API modules directly invoke AT instructions and communicated with Modem；
Step 704：The APDU transmitted instructions are needed to be sent to transparent transmission APDU package modules client；
Step 705：Transparent transmission APDU package modules be sealed with CLS, the INS that can pass through Modem to original APDU instructions
Dress；
In the transparent transmission mode using extension, it is necessary to call transparent transmission APDU package modules to be used to APDU instructions to be passed
Under mode encapsulate
Wherein, CLS, INS are the CLS, the INS that can be used in transparent transmission APDU instructions obtained by step shown in Fig. 6.
Step 706：Transparent transmission APDU package modules call AT+CGLA to instruct, and the APDU after encapsulation is transmitted to Modem and is instructed；
Step 707：The APDU instructions whether Modem is delivered successfully after encapsulation are judged, if so, turning to step 708；If it is not,
Turn to step 709；
For the APDU instructions after encapsulation, instructed and issued to Modem by 3GPP27.007AT+CGLA, if Modem is not
Successfully issue the instruction or SIM card have rejected the instruction（Return code non-9000）, that is, prove CLS, INS used in transparent transmission APDU
Modem or SIM card can not successfully be passed through（For example this transmission still uses CLS, INS of last time success transparent transmission, but during this period
It is new in SIM card that application is installed, and the application conflicts with CLS, INS of last time success transparent transmission, so as to cause this to fail）, it is necessary to
CLS, INS that transparent transmission APDU negotiation modules consult a set of transparent transmission that can succeed again are re-called, step 708 is turned to.
If the APDU instructions after encapsulation can successfully be pass-through to SIM card, when SIM card Applet does not recognize CLS, the INS
After need to call transparent transmission APDU modules in SIM card to be parsed, transparent transmission APDU modules compare itself current storage be used for it is transparent
CLS, INS of transmission, if unanimously, removing CLS, INS, P1, P2, the data in Data only being returned into SIM card Applet
Carry out subsequent treatment；If it is inconsistent, thinking to be not intended to transparent transmission, return to SIM card Applet and carry out error handle
（Such as return to the CLS/INS mistakes do not supported）.
After SIM card Applet terminates to instruction processing, reply data is still given transparent transmission APDU modules in SIM card and sealed
Dress, regardless of Applet results, transparent transmission APDU modules all add 9000 success status words after original reply data
Return, to pass through Modem.
Step 708：Judge whether SIM card successfully returns to 9000 yards and reply data, if so, turning to step 711；If it is not,
Turn to step 709；
Step 709：Transparent transmission APDU negotiation modules are called, is reacquired by step shown in Fig. 6 and can be used in transparent transmission APDU
CLS, INS of instruction；
Step 710：Transparent transmission APDU package modules are notified using CLS, the INS newly consulted, to turn to step 705；
Step 711：Response parsing module is called, the reply data that SIM card is returned is sent to standard OpenMobile
API module；
9000 status words that Modem returns to Applet+response is the response parsing mould that data are sent in mobile terminal
Block, is removed after 9000 status words by response parsing module, reply data is sent into standard OpenMobile API modules.
Step 712：Standard Open Mobile API modules carry out logical process to reply data and return to result
To client.
The data transmission method of the present invention, the APDU for being actually needed transmission is instructed and is encapsulated in transparent transmission APDU instructions, is led to
Cross Modem and transparent transmission APDU instructions are sent to SIM card, APDU instructions are sent to SIM card so as to realize, need not be to client
