Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and device of realizing adaptation of communication protocol of intelligent card.
Background technology
All communication systems are all comprised of software systems and these two parts of hardware system, and communication protocol is very important basic link in software systems, it can be understood to the platform that key interface between software function and particular hardware and software function realize, based on communication protocol, communication system completes the transmission of information with mutual.
In smart card communications field, there is at present various communications protocols type, such as TypeA, TypeB, TypeC, TypeD etc.Existing intelligent card chip generally can be supported these two kinds of communication protocol type of TypeA and TypeB, can also supporting of having comprises the communication protocol of the other types of TypeC, when the communication protocol type of smart card operating system Set For Current and the communication protocol type of terminal are not mated, just communication protocol type corresponding to smart card operating system need to be converted to consistent with the communication protocol type of terminal, thereby guarantee can to communicate by letter normally between smart card and terminal.
Prior art one has proposed a kind ofly by user, manually for smart card operating system, to select the method for communication protocol type, in the method, by user, judged whether to carry out the conversion of the communication protocol that smart card operating system is corresponding, and by user, to smart card transmit operation instruction, to control smart card, communicate protocol conversion when definite need to conversion.Generally in smart card performance history, the corresponding relation of the communication protocol type that the pre-defined operational order of smart card developer and smart card are supported, when smart card receives the operational order of user's transmission, according to this corresponding relation, by communication Protocol Conversion corresponding to smart card operating system, be communication protocol type corresponding to operational order sending with user.The method can realize the conversion of simple communication protocol of intelligent card, but needs user to judge whether conversion, and due to the subjectivity of user behavior, the opportunity that therefore judgement is changed is inaccurate, thereby makes to switch weak effect; And the realization of the method needs user to be familiar with the corresponding relation of protocol type and operational order and protocol type, and then determine whether to carry out the conversion of protocol type.And in fact a lot of users protocol type corresponding to unclear concrete application so the realization of the method is high to user's operation requirements, and because the conversion between communication protocol is all manually completed by user, have caused inconvenience to user.
Prior art two has proposed a kind of Frame that differs from the current communication protocol type of card intelligence sheet by reception, with the protocol type of selecting smart card system to be supported, particularly:
Smart card is after receiving the instruction that differs from current communication protocol type, chip is automatically by the flag set of certain register of inside, smart card can check the set situation of this register-bit in routine processes subsequently, if find this register set, enter setting processing module, this module is configured to the type corresponding with the instruction receiving by smart card, thereby realizes type conversion.Current all smart cards have one to wait for the state (being holding state) receiving, if smart card receives the Frame identical with current protocol type, smart card is jumped out this holding state, and carries out subsequent operation.If but smart card receives the Frame that differs from current protocol type, smart card may be jumped out holding state, also may not jump out holding state, this depends on performance and the residing radio-frequency field environment of intelligent card chip completely.Generally, intelligent card chip is after jumping out holding state, by one for identifying wrong marker bit set, if but smart card differs from the Frame of current protocol type but does not jump out holding state receiving, just can set for identifying wrong marker bit set, cause the repeatedly reception instruction different from current protocol type and cannot carry out self-adaptation, thereby affect user's proper communication.
In fact, in a lot of practical application, electrical specification due to intelligent card chip itself, and the difference of specific environment (such as magnetic field intensity, depth of modulation, sequential etc.), the simple stability that relies on chip self character, stability to guarantee self-adaptation application is inadequate, tends to run into the situation that self-adaptation success ratio is very low.For example, same method is applied to different smart cards, and probably because the difference of intelligent card chip characteristic causes some smart card can self-adaptation, and other smart card can not self-adaptation; Some smart card is adaptive effective, and the adaptive effect of other smart card is bad.Equally, also may be due to environment for use, a same sheet smart card can self-adaptation in some environment, but lower under other environment just cannot self-adaptation; In some environment, self-adaptation is effective, but self-adaptation effect is bad under other environment.
In sum, in existing communication protocol of intelligent card conversion method, for the mode that needs user to participate in, poor and the user of conversion effect operates inconvenience, for the mode of self-adaptation conversion, the weak effect of conversion, and there is the problem that cannot carry out protocol conversion in time and affect user's proper communication.

Embodiment
In order to provide, improve the accuracy of adaptation of communication protocol of intelligent card and the implementation of self-adaptation effect, the embodiment of the present invention provides a kind of method and device of realizing adaptation of communication protocol of intelligent card, below in conjunction with Figure of description, the preferred embodiments of the present invention are described, be to be understood that, preferred embodiment described herein only, for description and interpretation the present invention, is not intended to limit the present invention.And in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.
According to the embodiment of the present invention, first a kind of method that realizes adaptation of communication protocol of intelligent card is provided, by the method, can realize exactly the self-adaptation of the communication protocol of communication protocol in smart card and terminal.
Fig. 1 realizes the method flow diagram of adaptation of communication protocol of intelligent card in the embodiment of the present invention, as shown in Figure 1, mainly comprise the steps:
The running state information that step 102, basis are obtained determines whether the communication protocol of this smart card configuration mates with the communication protocol of terminal support;
If step 103 is determined the communication protocol of this smart card configuration, do not mate with the communication protocol of terminal support, perform step 104, otherwise execution step 105;
According to the embodiment of the present invention, after powering on, smart card to be configured and initialization this communication protocol of intelligent card, and concrete processing procedure as shown in Figure 2, comprises the steps:
The state that smart card enters before radio-frequency field is POWER-OFF, and noenergy state, enters after radio-frequency field, and smart card obtains energy by magnetic Field Coupling, and intelligent card chip powers on and carries out following flow process:
In this step, the configuration information obtaining comprises protocol type, transfer rate and other parameter and variable relevant to communication connection, for subsequent treatment, uses.
The configuration information initialization smart card operating system that step 203, basis are obtained;
The initialization of communication protocol after being completed smart card and powered on by said process, smart card, after the initialization that completes communication protocol, enters the self-adaptive processing flow process of communication protocol of intelligent card.
In above-mentioned flow process, in step 201, default communication protocol type can be accomplished in several ways, and for example, sets in advance communication protocol type table, and this table comprises various communications protocols type, and priority corresponding to each communication protocol type.After smart card powers on, the communication protocol type of the first priority is defined as to the current communication protocol type that will configure of smart card go forward side by side line correlation configuration and initialization.Wherein, in communication protocol type table, the priority of each communication protocol type dynamically updates according to init state and self-adaptation state, specific as follows:
For convenience of understanding, suppose to set in advance communication protocol type table and comprise A, B, C, the communication protocol of D Four types, and priority is followed successively by earth by height: A-> B-> C-> D, according to this communication protocol type table, after smart card powers on, the communication protocol of determining category-A type is as the current communication protocol that will configure of smart card and carry out relevant configuration and initialization, then the update strategy based on default upgrades this communication protocol type table, wherein update strategy can arrange flexibly, for example this update strategy can be set to: priority corresponding to the current communication protocol type having configured is set to minimum, the priority update of the communication protocol type that communication protocol type table can be comprised according to this update strategy is B-> C-> D-> A, the priority of communication correspondence that is category-B type is the highest, if the communication protocol of the category-A type having configured current is not mated with terminal communication protocol, the communication protocol in smart card is converted to category-B type by category-A type.
Above-mentioned communication protocol type table upgrades during except initialization after terminal powers on, and can also upgrade according to self-adaptation result, specific as follows:
When the communication protocol that the communication protocol configuring in determining smart card is supported with terminal is mated, utilize the communication protocol of current smart card configuration to upgrade communication protocol type table, the communication protocol type that is about to current smart card configuration is updated to the first priority in communication protocol type table.
Should be appreciated that the above update strategy for communication protocol type table can arrange flexibly, does not enumerate herein.And communication protocol type table only, for a kind of existing way of the various communications protocols type that sets in advance in the embodiment of the present invention, can also exist with the alternate manner beyond list.And, in actual applications, the priority of a communication protocol type in communication protocol type table also can be set, and the random wherein a kind of communication protocol type of selecting during communication protocol in carrying out configurable smart card, and the communication protocol type of selection is designated and is configured, upper while once selecting this communication protocol type not at the row of selection until in communication protocol type table all communication protocol type be all identified as and configure.
In one embodiment of the invention, the running state information of the communication protocol of the current configuration of smart card comprises:
This smart card completes the standby time information (convenient for subsequent descriptions, to be called A information) after current communication protocol in configuration; Or/and,
This smart card is to the process state information of the data that receive (convenient for subsequent descriptions, to be called B information).
Wherein:
The standby time that smart card completes after current communication protocol in configuration can, after completing communication protocol of intelligent card configuration, be realized by counter; Obtaining A information can determine by reading the count value of counter;
Smart card can be realized by the bit-identify in register the treatment state of the data that receive, when smart card to the execution of the data that receive processing, by this bit-identify set, therefore, obtaining B information can take and determine that treatment state is as untreated or processed by reading the SM set mode of this bit-identify.
Be to be understood that, the expression mode of above-mentioned cited A information and B information is only for implementing a kind of mode of the embodiment of the present invention, can be provided for flexibly representing as required the mode of A information and B information, for example, A information can also represent by other timing device or Trigger of time, and B information can also represent by low and high level, represents processed when high level, during low level, represent untreatedly, do not enumerate herein.
As shown in Figure 3, after completing the configuration of communication protocol of intelligent card and initialization, when the running state information of the communication protocol of the current configuration of smart card comprises A information and realize the counting to the standby time in A information by counter, the adaptive process of communication protocol of intelligent card comprises:
The communication protocol that step 305, the communication protocol of determining the current configuration of smart card are supported with terminal is mated, and communicates and be connected with terminal according to the communication protocol of the current configuration of this smart card.
Generally, smart card complete power on and initial configuration after can enter holding state, wait for extraneous instruction.Before this this holding state, initialization is also opened counter.If smart card is not still jumped out holding state before counter overflow, the extraneous Frame instruction that has probably sent the communication protocol type that differs from the current configuration of smart card of explanation, and because the reason of intelligent card chip own has been made the false judgment of not receiving protocol instructions, cause smart card always in holding state, thereby cannot communicate the self-adaptation of agreement.For fear of this situation, in above-mentioned flow process, when determining that according to A information the standby time of smart card after configuration completes current communication protocol surpasses setting duration, think that the communication protocol type of the current configuration of smart card and the communication protocol type of terminal support do not meet, determine that the communication protocol of this smart card configuration is not mated with the communication protocol of terminal support.
As shown in Figure 4, after completing the configuration of communication protocol of intelligent card and initialization, when the running state information of the communication protocol of the current configuration of smart card comprises B information and represents the treatment state in B information by the bit-identify in register, the adaptive process of communication protocol of intelligent card comprises:
The communication protocol that step 404, the communication protocol of determining the current configuration of smart card are supported with terminal is mated, and communicates and be connected with terminal according to the communication protocol of the current configuration of this smart card.
Generally, smart card is when receiving the Frame being consistent with communication protocol type own, smart card can be processed this Frame according to normal flow, but if smart card is while receiving the Frame that differs from communication protocol type own, although smart card can be jumped out holding state, but may exist because intelligent card chip cannot be processed the Frame of receiving and again get back to holding state, thereby cannot communicate the self-adaptation of agreement.Appearance for fear of this situation, in above-mentioned flow process, in described process state information while being untreated, think that the communication protocol type of the current configuration of smart card and the communication protocol type of terminal support do not meet, determine that the communication protocol of this smart card configuration is not mated with the communication protocol of terminal support.
As shown in Figure 5, after completing the configuration of communication protocol of intelligent card and initialization, when the running state information of the communication protocol of the current configuration of smart card comprises A information and B information, and by counter realize the counting of the standby time in A information, while representing the treatment state in B information by the bit-identify in register, the adaptive process of communication protocol of intelligent card comprises:
The communication protocol that step 507, the communication protocol of determining the current configuration of smart card are supported with terminal is mated, and communicates and be connected with terminal according to the communication protocol of the current configuration of this smart card.
In above-mentioned flow process, the process that reads the value of counter and judge according to the value of the counter reading with read setting for representing the bit-identify state of register and the execution sequence interchangeable of the process that judges according to the bit-identify state reading of B information, in judgement when representing the bit-identify set of register of B information, further read the value of counter, and when the value of judgement counter is not overflowed, execution step 507, communicates and is connected with terminal according to the communication protocol of the current configuration of this smart card.
Generally, when smart card is jumped out after holding state, smart card checks the state of counter, if determine, counter does not overflow, illustrate in setting duration, smart card has received the data that the external world is transmitted, if the data that receive are mated with the communication protocol type of the current configuration of smart card, smart card is processed according to normal flow.If but do not mated, smart card can exist because processing and enter holding state in follow-up processing procedure, if the instruction type of next receiving all differs from the communication protocol type of the current configuration of smart card, card can repeat the process of " jump out standby mode-cannot process and receive instruction-again enter standby mode " always.
Therefore, according on the basis of counter judgement, further for representing that bit-identify state in the register of B information is as Rule of judgment.When smart card receives the data command of the communication protocol type that differs from current configuration and this instruction has been carried out to processing, the bit-identify set in this register, expression smart card had been received the instruction of mating with the communication protocol type of current configuration.
In order to improve adaptive accuracy, in this embodiment, will determine that the communication protocol of described smart card configuration with the unmatched condition setting of communication protocol of terminal support is: smart card completes standby time after current communication protocol in configuration and surpasses and set duration and be untreated to the process state information of the data of reception.
In above-mentioned flow process, at step 505 judgement bit-identify, not set in the situation that, further judgement is in setting duration, and treatment state is whether the number of times of untreated (being not set of bit-identify) surpasses set point number, setting duration when wherein, setting duration judges counter.Idiographic flow as shown in Figure 6, comprising:
Step 601, initialization are also opened counter;
Step 602, read the value of counter;
Step 603, judge whether the value of counter overflows, whether surpass and set duration, if so, perform step 607, otherwise execution step 604;
Step 604, read setting for representing the bit-identify state of the register of B information;
Step 605, judge the whether set of this bit-identify, if not, perform step 606, if so, perform step 608;
Step 606, in setting duration bit-identify not the number of times of set whether surpass set point number N, if so, perform step 607, if not, execution step 608;
Step 607, the configuration of returning to communication protocol of intelligent card and initialization flow process (being the flow process shown in Fig. 2);
The communication protocol that step 608, the communication protocol of determining the current configuration of smart card are supported with terminal is mated, and communicates and be connected with terminal according to the communication protocol of the current configuration of this smart card.
In this embodiment, by judgement set bit-identify in duration not the number of times of set whether surpass set point number N, further improved the accuracy of adaptation of communication protocol.
In further embodiment of this invention, the running state information of the communication protocol of the current configuration of smart card is except comprising A information, or/and, beyond B information, also further comprise:
Whether this smart card receives after the data of the communication protocol type that differs from current configuration the information (convenient for subsequent descriptions, to be called C information) in holding state.Particularly, whether smart card can be realized by the bit-identify in register in holding state after receiving the data of the communication protocol type that differs from current configuration, after smart card receives the data of the communication protocol type that differs from current configuration also in holding state, by this bit-identify set, therefore, obtain SM set mode that C information can be by reading this bit-identify to determine whether in holding state.
As shown in Figure 7, after completing the configuration of communication protocol of intelligent card and initialization, when the running state information of the communication protocol of the current configuration of smart card comprises A information and C information, and by counter, realized the counting of the standby time in A information, by the bit-identify in register, represented that C information is whether during in holding state, the adaptive process of communication protocol of intelligent card comprises:
The communication protocol that step 707, the communication protocol of determining the current configuration of smart card are supported with terminal is mated, and communicates and be connected with terminal according to the communication protocol of the current configuration of this smart card.
In above-mentioned flow process, when determining that according to A information standby time surpasses setting duration and determines also in holding state according to C information, determine that the communication protocol of this smart card configuration is not mated with the communication protocol of terminal support.And in above-mentioned flow process, the execution sequence interchangeable of the process judging according to the value of counter and the process that judges according to the SM set mode of bit-identify in register, at the bit-identify of register for representing C information not during set, when reading Counter Value and this Counter Value and not overflowing, execution step 707, communicates and is connected with terminal according to the communication protocol of the current configuration of this smart card.
As shown in Figure 8, after completing the configuration of communication protocol of intelligent card and initialization, when the running state information of the communication protocol of the current configuration of smart card comprises B information and C information, and by the bit-identify in register, represent that treatment state in B information and C information are whether during in holding state respectively, the adaptive process of communication protocol of intelligent card comprises:
The communication protocol that step 806, the communication protocol of determining the current configuration of smart card are supported with terminal is mated, and communicates and be connected with terminal according to the communication protocol of the current configuration of this smart card.
In above-mentioned flow process, according to B information, determining that process state information is untreated and while determining also in holding state according to C information, determines that the communication protocol of described smart card configuration is not mated with the communication protocol of terminal support.And in above-mentioned flow process, according to for represent process that the bit-identify of the register of B information judges with according to for representing the execution sequence interchangeable of the process that the SM set mode of the register bit-identify of C information judges, at the bit-identify of register for representing C information not during set, read when representing the bit-identify of register of B information and this bit-identify set, execution step 806, communicates and is connected with terminal according to the communication protocol of the current configuration of this smart card.
As shown in Figure 9, after completing the configuration of communication protocol of intelligent card and initialization, when the running state information of the communication protocol of the current configuration of smart card comprises A information, B information and C information, and by counter, realized the counting of the standby time in A information, by the bit-identify in register, represented that treatment state in B information and C information are whether during in holding state respectively, the adaptive process of communication protocol of intelligent card comprises:
The communication protocol that step 909, the communication protocol of determining the current configuration of smart card are supported with terminal is mated, and communicates and be connected with terminal according to the communication protocol of the current configuration of this smart card.
In above-mentioned flow process, set duration, according to B information, determine that process state information is untreated and determines whether that according to C information information in holding state is when being determining that according to A information standby time surpasses, determine that the communication protocol that described smart card configures do not mate with the communication protocol of terminal support.And, according to the deterministic process of A information and executing, according to the deterministic process of B information and executing and according to the execution sequence interchangeable of the deterministic process of C information and executing, no matter with which kind of execution sequence, need to meet, the count value of counter do not overflow, for represent B information register bit-identify set and for the bit-identify of register that represents C information not during set, execution step 909, communicates and is connected with terminal according to the communication protocol of the current configuration of this smart card.
At Fig. 8, shown in Fig. 9 in flow process, when the running state information of the communication protocol of the current configuration of smart card at least comprises B information, when judgement is for the bit-identify of register that represents B information not in the situation of set, further judgement is in setting duration, treatment state is whether the number of times of untreated (being not set of bit-identify) surpasses set point number, if surpass set point number, carry out and return to the configuration of communication protocol of intelligent card and the step of initialization flow process, if do not surpass set point number, carry out according to the communication protocol of the current configuration of this smart card and communicate with terminal the step being connected, concrete treatment scheme is consistent with ultimate principle shown in Fig. 6, be not described in detail herein.
Above in arbitrary flow process, when determining that the communication protocol of the current configuration of smart card is mated with the communication protocol of terminal support, priority by the communication protocol type of the current configuration of smart card in communication protocol type table is made as the first, and object is that after avoiding smart card to power on, communication protocol type fixes and the drawback brought.For example, protocol type after smart card powers on is at every turn all TypeA, and the communication protocol type of terminal support is TypeB, although the each data interaction of smart card and terminal can be ensured by above-mentioned adaptation mechanism so, but after powering on, all to carry out same poll by protocol type table at every turn, reduce efficiency.So after having determined the communication protocol type that smart card is identical with the communication protocol of terminal support, just upgrade according to the method described above communication protocol type table, make smart card next time can just enter into for the first time corresponding handling procedure after powering on, and the type poll of needn't losing time again to carry out.
The above method providing according to the embodiment of the present invention, can realize the self-adaptation of communication protocol of intelligent card, in practical application, when complete the configuration and initialization of communication protocol according to said method after, can further detect and whether have protocol error, for example crc error, check bit mistake, fifo error etc., if made mistakes, get back to the instruction of again waiting for terminal in holding state, otherwise assert that instruction is correct.If by the check that makes mistakes, count initialized device, be that initialization smart card completes the standby time after current communication protocol in configuration, and, set is for representing the bit-identify of the register of B information, be about to smart card and the treatment state of the data command receiving be updated to processed, and current communication protocol type is updated to the first priority at communication protocol type table.
Describe for example the adaptive implementation method of communication protocol type of the present invention below in detail, suppose that the communication protocol type priority arranging in the current communication protocol type table of smart card is A-B-C by high order on earth, the communication protocol type of terminal support is TypeC, and smart card operating system adaptive process is as follows:
After the first step, smart card enter radio-frequency field, chip is obtained energy and is powered on by magnetic Field Coupling, then according to communication protocol type table, communication protocol type is configured to TypeA, and upgrading communication protocol type table, in the communication protocol type table after renewal, all types of priority order is from high to low B-C-A.
Second step, smart card setting are also opened counter, enter holding state, the counter overflow event of waiting for extraneous instruction and may occurring.
The 3rd step, smart card are jumped out from holding state, and due to the difference of chip characteristics, smart card has likely received that TypeC protocol instructions just jumped out, and also may receive that the instruction of TypeC is not still jumped out, until counter overflow is just jumped out.
If it is owing to having received TypeC instruction that smart card is jumped out, because the communication protocol type of the current configuration of smart card is TypeA, smart card will enter into the treatment scheme of TypeA so, in to the process of TypeC instruction process, certainly have generation protocol error, thereby this smart card comes back to holding state.If again receive the instruction of TypeC under holding state, smart card can repeat above process again, until the N time time, smart card is identified for representing the bit-identify set not yet in the register of B information, determine that the communication protocol type of the current configuration of smart card and the communication protocol type that terminal is supported are inconsistent, need conversion, enter the 4th step.
If it is because timer overflows that smart card is jumped out, directly determine that the communication protocol type of the current configuration of smart card and the communication protocol type that terminal is supported are inconsistent, need conversion, enter the 4th step.
The 4th step, smart card are configured to TypeB according to the priority orders in communication protocol type table by the communication protocol type of smart card, and upgrade communication protocol type table, in communication protocol type table after renewal, all types of priority order is from high to low C-A-B, and after this time configuration, the last communication protocol type of priority is TypeC.
The 5th step, smart card setting are also opened counter, enter holding state, the counter overflow event of waiting for extraneous instruction and may occurring.
The 6th step, smart card are received the protocol instructions of TypeC under holding state, because the communication protocol type of the current configuration of smart card is TypeB, therefore the instruction receiving is not still inconsistent with the protocol type of itself, so the same with above-mentioned flow process, the communication protocol type in smart card is converted to TypeC by TypeB.
The 7th step, smart card are received the protocol instructions of TypeC under holding state, meet with the communication protocol type of the current configuration of smart card, smart card is jumped out holding state, after determining that according to other deterministic process the communication protocol type of the current configuration of smart card and the communication protocol type of terminal support are consistent, for smart card operating system is set up and communicated by letter with terminal.
