Embodiment
Specifically describe below in conjunction with the implementation method and the device thereof of each accompanying drawing PHS mobile phone PIM card function of the present invention.
Though note that the function of PIM card is realized by corresponding software in this embodiment of the present invention.But, it will be understood by those skilled in the art that the various functions of PIM card obviously also can be realized by the various known hardware in this area, can be used for finishing the function of the interface between mobile phone and the PIM card as LTC1555L.(following will the specific descriptions).
The realization of the PIM card protocol software is described below in conjunction with Fig. 1-5.
Fig. 1 schematically shows the overall software hierarchy structure chart that PIM card protocol function is realized.As shown in Figure 1, PIM card agreement realizes that software adopts hierarchy, is divided into three levels, is respectively application layer, and transmission command layer and hardware driving layer, hardware driving layer segment task again and drive two sublayers.
Application layer is responsible for the control and the scheduling of whole protocol stack sofeware, accepts request from agreement and MMI (man-machine interface) layer, and this request is resolved, and gives the transmission command layer then.Similarly, the message that application layer is come Drive Layer is resolved, and sends to agreement and man-machine interface layer then.The transmission command layer to form corresponding transmission data units, sends to the hardware driving layer with formed transmission data units according to PIM technical standard deal with data then.The hardware driving layer cooperates hardware according to the authentic data exchange between realization of ISO7816-3 host-host protocol and the PIM card.
Fig. 2 schematically shows the detail message flow graph that PHS mobile phone PIM card function realizes.As shown in Figure 2, at L1, agreement and man-machine interface course application layer send a request message, and request PIM card is carried out corresponding operation.At L2, application layer is carried out interface interchange according to sending a request message of being received, and according to ISO7816 protocol data form and PIM card software interface requirement data is handled, is encapsulated.Then, at L3, transport layer will pass to the hardware driving layer via this transmission message that the corresponding interface obtains, and finish the transmission of message to lower floor's software.At L4, hardware driving course application layer sends Indication message, this message is the result who is used to refer to bottom layer driving or PIM card execution application layer single step request, content comprises success or failure indication, the data that the PIM card returns etc., and the request message content is the more request on upper strata in L1, it is service request to the PIM card, as ask authentication, this request will be resolved in application layer, be decomposed into concrete execution in step and finish.Then, at L5, application layer sends a notification message to agreement and man-machine interface layer, and application layer is resolved the message that bottom comes, and according to the software interface that defines executing result message is passed to corresponding upper layer software (applications).So far, finish request PIM card and carry out a certain function operations.
Below in conjunction with the flow chart of Fig. 3-Fig. 5, be example to read a short message from SIM card, each functional block of as shown in Figure 2 software is realized being elaborated
Fig. 3 schematically shows application layer software master control handling process.As shown in Figure 3, at step S10, incident is received, in this embodiment, this incident promptly requires to read a short message from SIM card.At step S11, this incident that is received is resolved.At step S12, judge the source of this incident.Come from the upper strata if judge this incident, then at step S13, judge whether to cancel this incident? if judge and to cancel incident, then read the process of short message from SIM card in step S16 cancellation.If judge the incident of not cancelling, then judged whether further that at step S15 other incidents handle? if judged result is a "Yes", then this incident that will require to read short message from SIM card at step S17 is put into buffer queue, treats to handle this incident that reads short message from the PIM card again after other event handlings finish in the buffer queue.If judge that at step S15 not having other incidents handles, then program forwards S14 to, and this incident is handled.If judge that at step S12 this incident comes from Drive Layer, then handles this incident at step S14.Treat that this event handling finishes, program forwards step S18 to, and processing finishes, that is, the result of processing is or carries out at once from the PIM card and read short message, perhaps temporarily this incident is put into buffer queue and handles after a while, perhaps cancels this incident.
The schematically illustrated application layer subprocess of Fig. 4 process chart.As shown in Figure 4, at step S21, check this request, the request that is is in the present embodiment read short message from the PIM card, and residing state determines this request is in which state of state machine.At step S22, judge whether this request is cancelled execution, that is to say whether this request is required to stop to carry out.If judged result is a "Yes", then move to the cancellation state at step S23.If judged result is a "No", then carry out the processing procedure of corresponding state at step S24.Then, judge whether unusual in previous step at S25? if judged result is a "Yes", then message is issued the user at step S27, and after carrying out reprocessing, check formation (S28, S29).Afterwards, judge whether non-NULL of formation at S31.If formation is " sky ", then return idle bit, otherwise, return non-idle bit.If the judged result at step S25 is a "No", then further judge whether to reach last current state at step S26.If judged result is a "Yes", then program forwards step S27 continuation execution to; Otherwise, transfer to next state at step S30.
Be that example is elaborated to above-mentioned flow process to read a short message from the PIM card below.After PIM card application layer is received the message that transmits on the upper strata, at first resolve, judge corresponding state after, this request is decomposed into following concrete steps realizes, as shown in table 1 below.
Table 1
Fig. 5 schematically shows Drive Layer software processes flow chart.As shown in Figure 5, receive incident, should the time promptly read a short message in the present embodiment from the PIM card at step S40.At step S41, extract the primitive head.At step S42, the original language head that is extracted is resolved.Afterwards, handling process is divided into 4 tributaries.In S421 to S4211 tributary, carry out the event handling relevant according to the resulting upper strata of primitive header parsing PIM access request with this request, promptly carry out from the PIM card and read short message.In S422 to S4221 tributary, carry out reset operation according to the resulting reset request of primitive header parsing.In S423 to S4231 tributary, carry out deactivation operation according to the resulting deactivation request of primitive header parsing.In S424 to S4241 tributary, if the resulting content of primitive header parsing is the other guide except above-mentioned three tributaries, then discharge internal memory, to be used for other processing.
