Embodiment
With reference to the accompanying drawings and the description of enclosing, can understand principle and the operation of being used for better by the multi-protocol data memory device of fabricator's preloading data according to various embodiment.
Note Fig. 1, Fig. 1 is according to the figure of an embodiment (subscriber identity module) SIM card 100.SIM card 100 is inserted in the main frame 99, and in this case, main frame 99 is to have honeycomb (GSM) phone of watching screen 98.(be that main frame 99 can be PDA, smart phone or other suitable equipment, as skilled in the art will be aware of in the example of Fig. 1 of SIM card perhaps, at card 100.) for other forms of storage component part (such as tag card, electronic key or demoder key), main frame can be personal computer, cashier's machine, DVB (digital video broadcasting) receiver or other suitable equipment, as skilled in the art will be aware of.SIM card 100 has eight outsides can insert conductive contact 111a-h, is used for communication and power supply.(write down as following, the multi-protocols smart card can have more than eight outside can insert conductive contact.) according to iso standard, contact C1111a is used for to card power supply (VSS 5V), and contact C5111e is (GRND) contact, ground, shown in Fig. 3 a.Communication between main frame 99 and the SIM card 100 is the set by the standard agreement that is collectively referred to as user model.
Main tradition (legacy) agreement that is used for subscriber identification is the ISO agreement, and it is worked according to the standard ISO of announcing 7816.Thereby the user model of SIM card 100 comprises the ISO agreement.When receiving from main frame 99 through (RST) the contact C2111b that resets to the suitable enabling signal of SIM card 100, processor 120 is from integrated circuit (IC) chip 132a loading data, and these data comprise the instruction that is used for the ISO agreement.
According to the ISO agreement, contact C2111b is used as (RST) line that resets, and contact C3111c is used as clock (CLK-ISO) line, and input and output (I/O) line that contact C7111g is used as data transmission (upload or download) (referring to Fig. 3 a).
Main frame 99 uses the ISO agreement to communicate by letter with SIM card 100, to provide user totem information to the mobile network.Therefore, when main frame 99 uses conventional I SO agreement, expectation is not interrupted (for example, if distribute alternative to ISO pin (even temporarily) during user model, then may interrupt) to the visit of ISO agreement (comprising contact C2111b, C3111c and C7111g).In the ISO agreement, utilize the timing signal that transmits through CLK-ISO contact C3111c, use I/O contact C7111g between SIM card 100 and main frame 99, synchronously to transmit data.
During user model,, also can move single data line SD/MMC agreement and be used for data transmission although contact C2111b, C3111c and C7111g are used to the ISO agreement.When from main frame 99 when processor 120 transmission is used to begin the signal (for example privately owned order) of SD/MMC agreement, processor 120 is from integrated circuit (IC) chip 132b loading data, these data comprise the instruction that is used for the SD/MMC agreement.For a line SD/MMC agreement, transmit clock signal (CLK-MMC) through contact C6111f, order (CMD) line is through contact C8111h, and single data line (DAT0) is through contact C4111d.Thereby a data line SD/MMC agreement makes contact C2111b, C3111c and C7111g can be used for using the subscriber identification information transmission of ISO agreement.Because the ISO agreement has only stayed three available contacts (being used to power supply and ground because of two in eight contacts), so in the embodiment in figure 1, need can not move simultaneously with the ISO agreement more than the agreement of three order wires, and can not operate in such as in the user model on the legacy equipment of main frame 99.
Note Fig. 2 now.In Fig. 2, SIM card 100 is shown as the fabricator's equipment 200 that is attached to.In the example of Fig. 2, fabricator's equipment 200 is for example to have the computer based that is used for the interface (not shown) that writes to SIM card to produce machine, make platform etc.SIM card 100 is being distributed to user (for example subscriber of cellular network) before, for example MNO agency's fabricator (may relate to many fabricators as mentioned above, when producing card.For example, each among the agency of the MNO of chip manufacturing person, smart card fabricator and custom card can be considered to fall in fabricator's the classification (rubric).It will be understood by those skilled in the art that in the part producing process to relate to other entities, and they also will fall in fabricator's the exercise question.Those skilled in the art also will understand, and an entity can be carried out a plurality of functions (for example single entities can be made chip, manufacturing and custom card, and loads the data at the customization of MNO)) be SIM card 100 preloading datas.Subsequently, for example, MNO distributes SIM card 100 to the subscriber.Equipment 200 be used for will be from the data of fabricator's equipment 200 prestrains and software upload to SIM card 100 nonvolatile memory 130 of SIM card 100 (and upload to particularly).For example, according to the use of intention or card distributor's requirement, the content of prestrain can comprise network settings, recreation or audio-visual content and (particularly, the data that upload can be specified by MNO) such as high-level softwares that be used to handle audio-visual content.
Because the fabricator is loaded into mass data on a large amount of SIM card, so thereby the fabricator is to being used for data are uploaded to fast that card is saved time for the fabricator and the high speed mechanism of money is interested.In order to increase message transmission rate, SIM card 100 is configured to be used in fabricator's pattern of data transmission.In fabricator's pattern, temporary transient forbidding ISO agreement, and three ISO contacts (C2111b, C3111c and C7111g) (in addition also had the single data line (DAT0) through contact C4111d as the parallel data line of SD/MMC agreement, thereby provided four data lines that are used for SD/MMC transmission), thus allow to be four times in the message transmission rate of the message transmission rate of user model.When the suitable enabling signal that receives from main frame 99 to SIM card 100, processor 120 is from the second integrated circuit (IC) chip 132b loading data, and these data comprise the instruction that is used for the SD/MMC agreement.
Perhaps, fabricator's pattern can comprise and is used for the custom protocol that high-speed data is uploaded.For example, except custom protocol was used many data lines, custom protocol can be the agreement similar to usb protocol.Perhaps, custom protocol can be similar to the high speed USB agreement, but also have an extra contacts that is used for external clock or other proper protocol, considers that as those skilled in the art this description will recognize.For example, the custom protocol based on high speed USB with external clock can be used 6 contacts, and the usb protocol with additional set of differential data line can use 7 contacts.Perhaps, custom protocol can comprise a plurality of differential data line and also have extra clock, and utilize 8 contacts.To understand as those of ordinary skill in the art, other custom protocol that substitute are possible.Alternate embodiment can comprise more than 8 contacts, thus at the data line utilization more than four contacts.To understand, such custom protocol can not be by the user capture that utilizes standard host equipment.
Fig. 3 a illustrates the distribution at the contact of the user model of SIM card 100 and fabricator's pattern according to an embodiment.In these two patterns, the power supply that provides on the C1111a of contact is 5V, and provides ground on the C5111e of contact.
When SIM card 100 is operated in user model following time, ISO and single data line SD/MMC agreement activity (active).Perhaps, according to the SIM standard, user model can comprise usb protocol and ISO compatible protocol,, can realize ISO agreement (realizing USB ICCD class) on USB that is.In the embodiment of Fig. 3 a, ISO agreement use contact C2111b is used to restart (RST), contact C3111c is used for clock (CLK-ISO) and contact C7111g is used for data I/O (I/O).Simultaneously, a data line SD/MMC agreement use contact C4111d (DAT0) is used for data transmission, contact C6111f is used for clock signal (CLK-MMC) and contact C8111h is used for order wire (CMD).
In the embodiment of Fig. 3 a, when SIM card 100 is operated in fabricator's pattern following time, all contacts are assigned to four data line SD/MMC agreements.Particularly, article four, data line SD/MMC agreement use contact C4111d (DAT0) is used for data transmission, contact C6111f is used for clock signal (CLK-MMC) and contact C8111h is used for order wire (CMD), as in the user model, but than user model, in fabricator's pattern, the SD/MMC agreement also utilizes contact C2111b, C3111c and C7111g to be used for parallel data line DAT1, DAT2 and DAT3, thereby when hypothesis is used identical clock rate, allow four times data transmission with the speed of user model.
In the embodiment of Fig. 3 a, the ISO agreement is called as first (user model) agreement, and multidata line SD/MMC agreement is called as second (manufacturing mode) agreement, and a data line SD/MMC agreement is called as the 3rd (user model) agreement.Contact C2111b, C3111c and C7111g are shared for ISO (first, user model) agreement and multidata line SD/MMC (second, fabricator's pattern) agreement, but can't help single data line SD/MMC (the 3rd, user model) agreement uses.Contact C4111d, C6111f and C8111h are utilized by second (fabricator's pattern multidata line SD/MMC) and the 3rd (the single data line SD/MMC of user model) protocol-specific ground.Contact C1111a and C5111e are used jointly by institute's protocols having.Thereby, article one, data line SD/MMC agreement is used five contact C1, C4, C5, C6 and C8 (111a, d, e, f, h), and the ISO agreement is used five contact C1, C2, C3, C5 and C7 (111a, b, c, e, g), and four line SD/MMC agreements are used all eight contact C1-C8,111a-h.
Fig. 3 b illustrates the alternative distribution of the contact of eight contact SIM card.In the embodiment of Fig. 3 b, usb protocol is used to transmit subscriber identification information in user model.Usb protocol need be used for the single contact of order wire and be used for two pins of differential data transmission, but does not need external clock.Thereby in the embodiment of Fig. 3 b, usb protocol is called as first (user model) agreement.
Usb protocol utilizes five contacts (be used for three contact C2CMD, C3IC_DP and C7IC_DM of data and be used for power supply and two contact C1VSS 5V on ground and C5GRND).In eight contact cards, this has only stayed three available data contact.Current standard-required for some legacy equipment (for example not supporting the hand-held set of usb protocol) compatibility, these three contacts are preserved for ISO agreement (for example, C4RST, C6CLK-ISO and C8I/O).Thereby in the embodiment of Fig. 3 b, the ISO agreement is called as the 3rd (user model) agreement.Thereby,, must transmit data according to ISO or usb protocol when the eight contact SIM card (in user model) of Fig. 3 b when using with main frame.On the SIM card that lacks high-speed internal clock and crystal oscillator, this is restricted to approximate 1M byte per second with the maximum data transfer rate in the user model.If will be used for parallel data transmission (for example above-mentioned multidata line SD/MMC), can realize that then faster data uploads more than three data contacts.Therefore, in order to realize high-speed data communication, SIM card can be programmed for and be operated in fabricator's pattern, in this fabricator's pattern, ISO and usb protocol are temporarily forbidden, and all available contacts are assigned to fast agreement (aforesaid multidata line SD/MMC or custom protocol).
Perhaps, for having the card (not being current standard SIM card) that can insert the contact more than eight outsides, fabricator's pattern can be used for extra contact even more parallel data line, obtains higher data upload speed.
Note Fig. 4 now, Fig. 4 illustrates the distribution at the contact of the user model of the alternate embodiment of multi-mode SIM card and fabricator's pattern.The user model of the SIM card of the embodiment of Fig. 4 comprises USB (first) agreement according to the standard of announcing, and utilizes contact C1 to be used for power supply (VSS), contact C3 to be used for that first differential data line (IC_DP), contact C4 are used for second differential data line (IC_DM), contact C5 is used for ground (GRND) and contact C8 is used for order wire (CMD).Contact C2, C6 and C7 are idle in user model.
In fabricator's pattern, the SIM card utilization of the embodiment of Fig. 4 customization (second pattern) agreement is used for the data upload of higher rate.Should be noted that according to the usb protocol standard two data pins are arranged at most.High speed USB uses the clock of these two data pins and faster (asynchronous), but the crystal oscillator of the costliness that this need be on storage card, and be considered to for SIM card and uneconomical.Thereby, not using standard high speed USB agreement, the fabricator utilizes customization (second) agreement at a high speed by two parallel data lines (utilizing contact C2 and C7 to be respectively applied for DAT0 and DAT1 line) being added to slow usb protocol, thereby uploading rate is doubled.Alternatively or additionally, the external clock that uses contact C6 as clock (CLK) contact can be added to customization (second, fabricator's pattern) agreement, allow card to use with synchronous communication by the definite speed of the high-frequency clock of main process equipment.
Thereby, in the embodiment of Fig. 4, contact C1, C3, C4, C5 and C8 be by first, the common used of user model agreement and second, fabricator's mode protocol, and contact C2, C6 and C7 be only by second, fabricator's mode protocol special-purpose contact of using.
Fig. 5 is the process flow diagram of exemplary method of the operation of diagram multi-protocol data memory device (for example multi-protocols SIM card).The multi-protocol data memory device has two mode of operations, fabricator's pattern 517 and user model 523.In step 510, device is powered on, and initialize signal is sent to this device.Then, in step 512, which kind of initialize signal operation has sent according to depending on, promptly has been user model initialize signal (" Y ") or is not that in two kinds of patterns of (" N ") one or another advance.The example of user model initialize signal is the standard enabling signal that for example meets the standard of being accepted that is used for the single-mode SIM card, but not the example of user model signal is privately owned enabling signal.
If in step 512 enabling signal is not the user model enabling signal, then device enters fabricator's pattern 517.When device entered fabricator's pattern 517, this device began 518 and (for example customizes) agreement at a high speed.
In alternate embodiment, device can be configured to enter standard agreement 510 the time when powering on and consult (negotiation) sequence.Under these circumstances, between period of negotiation, specify the agreement (for example standard ISO or usb protocol) that is included in the user model 523 will be defined as sending user model enabling signal (" Y " in the step 512), and between period of negotiation, specify the agreement (for example multidata pin SD/MMC agreement or custom protocol) that is not included in the user model 523 will be defined as sending non-user model enabling signal (" N " in the step 512).
In another alternate embodiment, during the making of device, default mode that can data storage device is set to manufacturing mode.Under these circumstances, device is powered on 510 starters in fabricator's pattern 517, and step 510 and 512 can be considered to merge into single step.And, under these circumstances,, can forbid fabricator's pattern by default mode being changed into user model 523 in the ending of making.
After step 518, in step 520, the data of prestrain are uploaded to device.After the data of all prestrains were uploaded, in step 522, the fabricator was forbidden fabricator's pattern 517.The 522 fabricator's patterns 517 of forbidding can be temporary transient or permanent, and the 522 fabricator's patterns 517 of forbidding can be by any execution the in the multiple mode.For example, can close data storage device by (fabricator) and realize temporarily forbidding 522 fabricator's patterns 517 (in this case, step 522 and 540 can be considered to merge into single step).Perhaps, temporarily forbidding 522 can be made of reset device, makes device must be restarted so that be operated in fabricator's pattern 517.When data storage device is set to powering on during manufacture, give tacit consent under the situation about entering in the manufacturing mode, then forbid 522 and can the default mode of device be changed into user model 523 formations by (fabricator).In the embodiment of Fig. 5, under the situation of the pattern that can when starting, come specify devices, the default mode of device is changed into user model 523 will be considered to temporarily forbid fabricator's pattern 517 by order.In alternate embodiment, after default mode is changed into user model 523, then needs are reconfigured device so that in fabricator's pattern 517, operate this device.Under these circumstances, the default mode of device is changed into user model 523 and will be considered to for good and all forbid fabricator's pattern.As for the generalized case of for good and all forbidding fabricator's pattern 517, by for good and all forbidding fabricator's pattern 517, device only carries out in user model 523 subsequently, just looks like that it does not have fabricator's pattern 517 the same.In addition, for good and all forbid fabricator's pattern 517 and prevent that unauthorized user from using fabricator's pattern 517 to be used for the unauthorized access to device as " back door (back door) ".In alternate embodiment, data storage device can be configured to make when receiving privately owned order, and fabricator's pattern 517 is by (for good and all or temporarily) forbidding.Forbidding 522 gives memory device with order when in such embodiments, can be included in the ending of customization.
