As shown in Figure 2, except DCI message transmission unit 210, also comprise a DCI formation 220 and a DCI performance element 230 in the card external equipment 200.In Fig. 2, DCI message transmission unit 210 with the DCI message stores that receives in DCI formation 220.DCI formation 220 can be sorted to the DCI message that receives according to the type or the priority of message.230 each DCI message that rank the first of taking out from DCI formation 220 of DCI performance element are handled.DCI performance element 230 can make an explanation to the DCI message of taking out, and carries out corresponding operating according to the corresponding hardware device in the command driven card external equipment 200 in the DCI message.
Thus, utilize as shown in Figure 2 DCI can make each application program control card external equipment 200 in the smart card.In addition, the incident that triggers in the card external equipment 200 also can be under the operation of DCI message transmission unit 210, DCI formation 220 and DCI performance element 230, conversely by API in the smart card 100 to application program generation effect in blocking.Utilize above-mentioned DCI control card external equipment below with reference to the application program that two specific embodiments are described in detail in the smart card, and the card external equipment is passed through the DCI process of the interior application program of control card conversely.
In following examples, suppose that smart card 100 platforms are global platform (Global Platform:GP), and the API that expands for DCI specially is GP API on GP.Simultaneously, the DCI service that is used to call GPAPI is Global Service (global service).In addition, for convenience of description, in following examples, the GP in the smart card 100 also provides a card manager 140 and a registering unit 150 to be used to manage the interior application program of smart card.In view of similar in operation that blocks a manager 140 and a registering unit 150 and the prior art, thus all not shown in Fig. 2.According to concrete application, the operation that relates to card manager 140 and registering unit 150 in Fig. 4 and Fig. 5 can change according to actual conditions, even omit.
Fig. 4 shows the process flow diagram of smart card in the one embodiment of the invention 100 by DCI control card external equipment 200.
In Fig. 4, the application program 130 in the smart card 100 is for example wished the control card external equipment---the camera in the mobile phone is taken snapshot.As shown in Figure 4, at first, application program 130 is sent request to DCI GlobalService 125, to obtain DCI service (step S411).At this moment, DCI GlobalService 125 needs to check whether application program 130 has authority control card external equipment (step S413).If scope check passes through, then DCI Global Service returns to 130 1 DCIGlobal Service of application program and quotes (step S415).Application program 130 is quoted by this Global Service can call the DCI API 120 that is used to take snapshot, as api function Camera.TakeSnapShot () (step S417), promptly sends control request.Here, step S411～S417 calls the example of DCI API 120 by calling method of service.Alternatively, application program 130 can also directly be called corresponding D CI API 120.
In response to calling of application program 130, DCI API 120 needs at first to check whether caller (being application program 130) has the authority of the camera that uses card external equipment (mobile phone) 200.Particularly, DCI API 120 checks the authority (step S421) of application program 130 to 140 requests of card manager.Card manager 140 is to the registry entry (step S423) of registering unit 150 inquiry application 130, and after obtaining corresponding registry entry the authority (step S427) of (step S425) verification Application program 130.If authorization check passes through among the step S427, then block manager 140 and feed back to the DCIAPI verification by message (step S429).Here, according to actual needs, the checking procedure of API application programs also is omissible.
After verification is passed through, the interface parameters that DCI API 120 provides when calling API according to application program 130, establishment meets the DCI command messages (for example DCI command messages M340 shown in Fig. 3 B) of form shown in Fig. 3 A, and the DCI message of being created is sent to DCI message transmission unit 110 (step S430).Then, the DCI message transmission unit 1110 in the smart card 100 sends to DCI message transmission unit 210 (step S440) in the card external equipment 200 with the DCI message M340 that creates.Alternatively, at this moment, DCI message transmission unit 110 also can be represented the issued response messages of DCI command messages (step S442) to application program 130 feedbacks via DCI API 120 and DCI GlobalService 125.
In card external equipment 200, DCI message transmission unit 210 stores the DCI message M340 that receives in the DCI formation 220 (step S450).DCI formation 220 can be according to type and the right DCI message of priority sort (step S452) when accepting new DCI command messages M340.In this embodiment, suppose that this DCI command messages M340 comes the first place of DCI formation 220.
According to the method described in the foregoing description, any one application program 130 in the smart card can be passed through the operation of DCI control card external equipment 200 easily.In the above-described embodiments, the application program in smart card waits as long for, and DCI message transmission unit 110 sends feedback message to application program 130 immediately after sending DCI message M340.Alternatively, if application program 130 expectations obtain the feedback message from card external equipment 200, for example application program 130-1 wishes the volume status of inquirying card external equipment 200, and then DCI message transmission unit 110 can be waited for after sending DCI message from the DCI message in the card external equipment.
In the example of inquiry volume status, the DCI performance element 230 in the card external equipment 200 calls speaker drive, to obtain the volume of current loudspeaker.Then, DCI performance element 230 will obtain information volume and be packaged into the DCI message of form as shown in Figure 3A, and by DCI message transmission unit 210 this DCI message be returned to DCI message transmission unit 110 in the smart card.At this moment, this comprises the DCI message of volume status to the DCI message transmission unit 110 in the smart card to application program 130 feedbacks via DCI API 120 and DCI Global Service125 again.
Fig. 5 shows and blocks external equipment 200 acts on the application program in the smart card 100 by DCI a process flow diagram in the one embodiment of the invention.
In the example of Fig. 5, suppose that the application programs 130 in the smart card 100 receive that for card external equipment (as mobile phone) incident of incoming call is interested, then application program 130 wish can the transaction card external equipment in the incoming call incident.
In this case, as shown in Figure 5, application program 130 can be in advance by DCI API 120 these incoming call incidents of registration.For example, application program 130 can send the request (step S511) of registration incoming call incident to DCI API 120, and the call back function of this incoming call disposal route that application program 130 realizes self is provided simultaneously.At this moment, the authority that DCI API 120 can first application programs 130 is differentiated.Particularly, DCI API 120 can be to card manager 140 request authentications (step S512).Card manager 140 and then to the registry entry (step S513) of registering unit 150 inquiry application 130.After obtaining registry entry (step S514), whether card manager 140 has the right to monitor this incoming call incident (step S515) according to the record authentication application program 130 of registry entry.If authentication is passed through, then block manager 140 and return to DCIAPI 120 authentication success messages (step S516), in registering unit simultaneously application program 130 these incoming call incidents of registration.Then, DCIAPI 120 feeds back to application program 130 message (step S517) that succeeds in registration.Thus, application program 130 can successfully have been registered the incoming call incident.Repeated execution of steps S511～S517, other application program as application program 130-1 and 130-2, also can be registered its interested separately incident respectively.In above-mentioned steps,, then can save authentication process if application program 130 is considered to believable.
After registration, in case generation incident in the card external equipment 200, for example produced incoming call incident (incoming call) just, then DCI message transmission unit 210 can be known the generation (step S521) of this incident from the platform of card external equipment, and deposits this incident in the DCI formation 220 (step S522).Alternatively, after incident deposited DCI formation 220 in, DCI message transmission unit 220 can received the affirmation message (step S523) finished of storage afterwards, the message (step S524) of finishing dealing with to card external equipment platform feedback event.Repeat above-mentioned steps S521～S524, a plurality of incidents that take place in the card external equipment all can be stored in the DCI formation 220 successively.
In DCI formation 220, the incident that deposits in can be according to type and priority sort (step S530).In the embodiment of Fig. 5, suppose that the incoming call incident temporarily comes the first place of formation.Then, DCI performance element 230 in the card external equipment 200 can extract pending incident (for example incoming call incident) at one's leisure and the incident that extracts is packaged into the DCI event message from DCI formation 220, for example the DCI event message M350 (step S540) shown in Fig. 3 C.Then, DCI event message M350 is sent to DCI message transmission unit 110 (step S550) in the smart card 100 via DCI message transmission unit 210.
In smart card 100, according to the DCI event message that receives, DCI message transmission unit 110 announcement card managers 140 incidents of carrying out are handled (step S560), so that handle this incoming call incident.Each registry entry (step S571) in the card manager 140 traversal registering unit finds application program, for example application program 130 (step S572) in all cards of registering this incoming call incident.
After finding corresponding application 130, the call back function that card manager 140 provides when registering by DCI API 120 invokes application 130, i.e. the incoming call disposal route (step S581) of application program 130 realizations.Thereby, application program 130 can be handled from the incoming call incident (step S582) of blocking external equipment 200 according to the method that self realizes, and feed back to the response message that card manager 140 is handled success or not via DCI API 120 after handling, thereby but card manager 140 recording events are handled success or failure situations (step S583).At this moment, but card manager 140 repeating step S581～S583, and other have registered the application program of this incoming call incident sequence call, and the incoming call of carrying out is respectively separately handled.
After the application program of all registrations has all been finished processing to this incoming call incident, the response message (step S590) that card manager 140 disposes to card external equipment 200 feedback events via DCI message transmission unit 110.In card external equipment 200, DCI performance element 230 can obtain the response message (step S590) that this event handling finishes via DCI message transmission unit 210, and removes this incoming call incident (step S592) thus from the DCI formation.Next, DCI performance element 230 can be handled next incident.
In Fig. 4 and the described embodiment of Fig. 5, it will be understood by those skilled in the art that be not each response message all be necessary.For whether successful those be indifferent to processing embodiment, response message among Fig. 4 and Fig. 5 or feedback message can omit.
In addition, in the above-described embodiments, because DCI has the message format and the layering result of standard, DCIAPI 120 can design according to multiple mode.For example, api function can be designed to a certain operation at same card external equipment, also can be designed to the same operation at the different cards external equipment.Such as, can provide a general api function Close () for the operation of closing the card external equipment, its parameter can comprise the label of different cards external equipment.Thus, as long as when calling api function Close (), the application program is inserted the card external equipment label (that is, comprising corresponding card external equipment label in call request) that will close in the card in relevant parameters, then can utilize this Close () function to generate corresponding D CI command messages.Alternatively, DCI API 120 can also be the general controls function C ontrol () at the different operating of different cards external equipment.In this case, application program 130 can realize various controls by inserting parameters such as different card external equipment labels, functional label for api function Control ().Thus, DCI API can be adapted to various new card external equipment controls, thereby DCI can have very strong extensibility.
In addition, although above 3A～C has in conjunction with the accompanying drawings described the form of the DCI message that provides in the present embodiment, the form of DCI message is not limited to the situation shown in Fig. 3 A～C in the present invention.For example, the sub-message among Fig. 3 A can comprise a plurality of sub-message value fields, is used to fill in the status information of card external equipment feedback.For another example, the DCI message length field also can be placed on the beginning of whole message among Fig. 3 A.About the various definition or the distortion of DCI message, also be conspicuous to those skilled in the art.
Beneficial effect
In above embodiment, DCI provides unified interface function for each application program in the smart card.Thus, each application program need not to realize separately more self-defining APDU order, thereby has saved resource and cost.Simultaneously, DCI also provides the command messages of standard and the form of event message for different card external equipment.Thereby the smart card with DCI can be inserted on the different card external equipment, and can utilize its inner DCI API that these different card external equipment are controlled.Moreover in the above-described embodiments, DCI has the message format of standard, and has the hierarchy of transport layer and processing layer, and simultaneously, DCI API can also be designed to general purpose function.Thereby, can be with good expansibility according to DCI of the present invention.Even smart card also can be realized new card external equipment control behind the mask hair fastener.In addition, can on various communication protocols, transmit according to DCI message of the present invention, and no longer be confined to the ISO7816 standard.
Therefore, DCI according to the present invention provides a kind of general, unified and extendible solution route for the control between smart card and the card external equipment.The application of DCI can be supported the control of smart card to various card external equipment, thereby has opened up wide space again for the application of smart card.
