Because the terminal equipment in the snap gauge simulation models is in passive state usually, in order to guarantee the external read device data in the reading terminal equipment smoothly, terminal equipment can be a mobile host computers with a default setting in baseband processor 10 or the smart card 20 before receiving user's main frame selection instruction, be not provided with under the state of mobile host computers by the main frame selection instruction after the releasing activity main frame etc. automatically.Behind the default setting mobile host computers, if the mobile host computers of main frame that the user selects by the main frame selection instruction and default setting is identical, then to need not to reset this main frame be mobile host computers to terminal equipment, otherwise according to step switching activity main frame shown in Figure 4.
As shown in Figure 5, the mobile phone of an embodiment of the present invention selects SIM card 21 to may further comprise the steps for the idiographic flow of mobile host computers under reader mode:
S500: under reader mode, after CLF chip 31 powers on for SIM card 21, adopt single-wire-protocol to set up communicating by letter of physical layer and data Layer between SIM card 21 and the CLF chip 31, SIM card 21 is obtained in the CLF chip 31 the Reader RF Gate 32 that exists, and sets up and open in the SIM card 21 data transmission channel between the Reader RF Gate32 corresponding among the Reader Application Gate 22 and CLF chip 31; Meanwhile, the data transmission channel between the Reader RF Gate 32 corresponding in wherein Reader Application Gate and the CLF chip 31 is set up and opened to baseband processor 10.This moment is state because the terminal equipment in the reader mode has the initiative usually, and default mobile host computers can be set, and promptly keeps no mobile host computers state, when mobile phone need begin reader application, selects mobile host computers by the user.
S501: after the user selects mobile host computers to be a certain SIM card 21 from the man-machine interface 51 of mobile phone, man-machine interface 51 notice SIM card 21.If there are a plurality of SIM card 21 in mobile phone, then man-machine interface 51 is notified some SIM card 21 that the user chooses.
Reader Application Gate 22 in the S502:SIM card 21 initiates to activate request event EVT_READER_REQUEST to the Reader RF Gate 32 in the CLF chip 31, show this SIM card 21 requesting activation, the activation of this step is initiated mode and has been defined in the near-field communication international standard at present.
It is SIM card 21 that S503:CLF chip 31 is provided with mobile host computers, also can feed back to man-machine interface 51 and watches for users the result is set.
S504: when CLF chip 31 detects outside noncontact tag 60 near mobile phone and reading tag information.
Reader Application Gate 22 in the S506:SIM card 21 sends reading and writing data message WR_XCHG_DATA to the Reader RF Gate 32 in the CLF chip 31, then, Reader RF Gate 32 in the CLF chip 31 returns response message ANY_OK to SIM card 21, thereby finish the data communication between SIM card 21 and the outside noncontact tag 60, this step can repeat repeatedly.
S507: after data communication was finished, the Reader Application Gate 22 in the SIM card 21 sent and reads end EVT_END_OPERATION to CLF chip 31, and prompting CLF chip 31 is closed the RF field.
S508:SIM card 21 receives the message that CLF chip 31 is successfully closed the RF field, and the releasing activity main frame.
S509:CLE chip 31 recovers no mobile host computers state, waits for when next mobile phone begins reader application and selects mobile host computers once more by the user.
Mobile phone is under reader mode, if the user selects baseband processor 10 to be mobile host computers, then specifically select step and above flow process all fours, only need that the ReaderApplication Gate 22 in the SIM card 21 is replaced to Reader Application Gate in the baseband processor 10 and the Reader RF Gate 32 in the CLF chip 31 carries out data interaction.
In the present embodiment, when a mobile host computers was in running order, another mobile host computers led to a conflict thereby the user may send main frame selection instruction requesting activation.In this case, in order to guarantee normally carrying out of data communication, terminal equipment can be refused a back main frame selection instruction, and the current mobile host computers of prompting user is worked, and also can be selected whether to stop the reader application and the switching activity main frame of current active main frame by the user.For example working as the user has selected baseband processor 10 as mobile host computers, selected baseband processor 10 as mobile host computers once more in the near-field communication process of carrying out, then terminal equipment can be refused this request, the current mobile host computers of prompting user is worked, and is selected whether to stop the reader application of current active main frame by the user.
Among the another kind of embodiment, in order to prevent the selection conflict of mobile host computers,, can shield the options on the man-machine interface if the mobile host computers that the user selects is activated and starts working, behind terminal equipment releasing activity main frame, man-machine interface just provides the options of mobile host computers.

Step S601: it is a certain SIM card 21 that the user selects new mobile host computers from man-machine interface 51, and the api interface that mobile phone utilizes CLF chip 31 to provide in advance is by calling api function notice CLF chip 31SIM card 21 requesting activation.
It is SIM card 21 that step S602:CLF chip 31 is provided with mobile host computers, also can feed back to man-machine interface 51 and watches for users the result is set.
In for example a kind of execution mode, the api function that CLF chip 31 offers mobile phone is defined as SetActiveHost (), this function comprises a variable Host ID, the value of predeterminable Host ID is that " 01 " expression selects baseband controller 10 to be mobile host computers, and the value of Host ID is that " 02 " expression selects SIM card 21 to be mobile host computers.After the user selects mobile host computers by man-machine interface 51, api function will be called in mobile phone inside, and CLF chip 31 is provided with mobile host computers according to the value of Host ID.When CLF chip 31 obtains the Host ID of SetActiveHost () function, the value that also can at first the judge Host ID whether value with the corresponding Host ID of current mobile host computers is identical, if identical expression need not the switching activity main frame, can not make any subsequent treatment; If different, then switching the pairing main frame of Host ID that obtains is mobile host computers.
After setting was finished, CLF chip 31 also can provide return information to mobile phone, if handover success or need not to switch then but return information is TRUE, mobile phone shows new mobile host computers on man-machine interface 51; If be provided with for a certain reason that new mobile host computers is failed then return information is FALSE, mobile phone shows on man-machine interface 51 selects failure.
Step S603:CLF chip 31 detects an external RF field near mobile phone.
Card RF Gate 33 in the step S604:CLF chip 31 sends label detect-message EVT_FIELD_ON to the Card Application Gate 32 in the SIM card 31, and expression has detected the RF field that outside contactless reader 70 provides.
After Card RF Gate 33 in the step S605:CLF chip 31 activates, send and activate notification message EVT_CARD_ACTIVATED to the Card Application Gate 23 in the SIM card 21, notice SIM card 21CLF chip 31 has activated, and can begin to exchange Application Protocol Data Unit (APDU:Application Protocol Data Unit) order.
Card RF Gate 33 in the step S606:CLF chip 31 will transfer to Card Application Gate 23 in the SIM card 21 by data transfer messages EVT_SEND_DATA from the APDU of the contactless reader 70 in outside order, Card Application Gate23 in the SIM card 21 replys by data transfer messages EVT_SEND_DATA, thereby finish the data communication between SIM card 21 and the outside contactless reader 70, this step can repeat repeatedly.
Step S607: when the contactless reader 70 in outside no longer provides the APDU order, show that mobile phone finished snap gauge and intend to have used, the Card RF Gate 33 in the CLF chip 31 sends and activates close message EVT_CARD_DEACTIVED and finishes alternately to Card Application Gate 23 notification datas in the SIM card 21.
Step S608: when the RF field that CLF chip 31 detects outside contactless reader 70 is closed, Card RF Gate 33 sends snap gauge and intends end EVT_FIELD_OFF to the Card Application Gate 23 in the SIM card 21, if when mobile phone is in low electric weight or off-mode, can not send this incident.
Step S609: this contactless card simulation application is finished, automatic releasing activity main frame of mobile phone and notice CLF chip 31.
It is baseband processor 10 that step S610:CLF chip 31 can recover to be provided with mobile host computers.
