In the prior art; It is described from baseband chip to have the utility model embodiment on some equipment, if the described main baseband chip of the utility model embodiment with respectively do not adopt the intelligent card interface of standard from the connecting interface of baseband chip, but adopt self-defining interface; Then also need revise respectively from the hardware and software of baseband chip makes it meet the standard of self defined interface; Not only cost is high in the practical application, and realizes complicacy, and the debugging difficulty of program is also bigger.
For these reasons; In the described preferred embodiment of the utility model; Because main baseband chip and being connected respectively from baseband chip all through meeting the interface of smart card standard; Need not to revise respectively hardware configuration and corresponding software, so the said equipment of present embodiment can compatiblely well have the existing equipment from baseband chip from baseband chip.
Based on the content of above-mentioned each apparatus embodiments, specify said equipment below and how to realize many baseband chips share and access smart card.
With reference to Fig. 2, be the workflow diagram of the said a kind of many baseband chips share and access smart card device of the utility model embodiment.
Usually, at first start main baseband chip, main baseband chip through with being connected of smart card, accomplish the initial work of smart card;
Then, start each, do not have mandatory requirement from the boot sequence of baseband chip from baseband chip.
After main baseband chip started, main baseband chip was in holding state; After each starts from baseband chip, respectively also be in holding state from baseband chip.
When main baseband chip with respectively after baseband chip all starts, principal and subordinate's baseband chip is in the state of standby simultaneously, and therefore, main baseband chip possibly want to visit smart card, produces the information of visit smart card; Each also possibly want to visit this smart card from baseband chip, also can send the information of visit smart card through the intelligent card interface of standard to main baseband chip.If all produce the information of visit smart card at synchronization principal and subordinate baseband chip; Not only have in the then said main baseband chip and oneself visit the information of smart card; Also can receive the information of each visit smart card of sending from baseband chip, main baseband chip can all carry out buffer memory to the information of oneself visit smart card with each information from baseband chip visit smart card.If synchronization has only main baseband chip to produce the information of visit smart card, then main base-band information buffer memory self is visited the information of smart card; If synchronization has only one or more arbitrarily information from baseband chip generation visit smart card, then main base-band information buffer memory is from the information of baseband chip visit smart card.
Information for the so many visit smart card of main baseband chip buffer memory; Main baseband chip need be coordinated through the effect of master control, thereby makes the main baseband chip that is in standby simultaneously and can both send same sheet smart card to from the information that baseband chip is visited smart card separately.
In the practical application, main baseband chip can adopt various strategies to coordinate information and each information from baseband chip visit smart card of the main baseband chip visit smart card of buffer memory, and sends to said smart card one by one.
For example:
(1) sequencing according to buffer memory sends one by one;
Suppose an information a who sends a visit smart card from baseband chip earlier to main baseband chip; Main then baseband chip produces one and oneself visits the information b of smart card, and another also sends the information c of a visit smart card to main baseband chip from baseband chip then again.So, main baseband chip just sends to smart card according to the buffer memory order of a, b, c one by one.In the process of sending a, buffer memory b, c.
(2) priority or the professional priority set according to the user are sent one by one;
The priority of said business such as 3G business have precedence over the 2G business, and the 4G business has precedence over the 3G business, or the like.
The priority that said user sets is meant: allows the user to set up the priority level of transmission on their own, sets incoming call like the user and have precedence over short message, or the like.
(3) preferentially transmit each information, and then the information of oneself visiting smart card is sent to said smart card from baseband chip visit smart card to said smart card;
This strategy is the other side's principle of priority, and promptly main baseband chip is preferential transmits the information of the visit smart card of sending from baseband chip, and own information of visiting smart card is postponed transmission.
(4) preferentially the information of oneself visiting smart card is sent to said smart card, and then transmit each information from baseband chip visit smart card to said smart card.
Opposite with above-mentioned strategy (3), this strategy is the own principle of priority of main baseband chip.
Several kinds of strategies of more than enumerating can also can be set according to self-demand by the user by factory settings.
Main baseband chip can adopt the combination of any strategy or several kinds of strategies; At main baseband chip with under the situation of baseband chip standby simultaneously; The information of oneself visiting smart card and each information from baseband chip visit smart card are issued smart card one by one through coordinated mode; Thereby make the same sheet smart card of a plurality of baseband chip share and access, standby when realizing communicating by letter cross more.
Certainly, outside the above-mentioned strategy of enumerating, practical application can also have other strategy, and the utility model embodiment does not do qualification to this.
By on can know, in the process of many baseband chips share and access smart card, be responsible for true mutual with smart card by main baseband chip, respectively from baseband chip respectively forwarding realization through main baseband chip and smart card alternately.The more important thing is; Said main baseband chip can keep mutual with smart card with each from baseband chip simultaneously; Said " simultaneously " is meant: main baseband chip all is in holding state with each from baseband chip, and main baseband chip plays the master control effect, can be with the information of oneself visiting smart card and each information from baseband chip visit smart card; Arrangement according to certain strategy sends to said smart card respectively; Thereby realize many baseband chips share and access smart card, and said share and access need not to carry out the switching of baseband chip, thereby realized the standby simultaneously of real multi-communication standard.
The many baseband chips of this single deck tape-recorder possess the ability of multi-communication standard standby simultaneously; Can select the baseband chip of required communication standard flexibly as required, and after new communication standard occurs, can provide quickly and possess the equipment that multi-communication standard is treated capabilities simultaneously than other method.
Based on content embodiment illustrated in fig. 2, the utility model also provides the embodiment that is more preferably, and is specific as follows:
Before the main baseband chip of step 203 sends to smart card with the information of the visit smart card of buffer memory, main baseband chip judge earlier current whether carrying out baseband chip and smart card alternately.Wherein, said baseband chip can be main baseband chip, promptly whether is carrying out the operation of main baseband chip visit smart card; Said baseband chip also can be from baseband chip, promptly whether is carrying out certain operation from baseband chip visit smart card.
If current the mutual of baseband chip and smart card that do not carry out, then main baseband chip can send to smart card with the information of the visit smart card of buffer memory.Concrete, main baseband chip selects the information of the visit smart card of a buffer memory to send to smart card according to the above-mentioned strategy that presets.
If current the mutual of baseband chip and smart card that carrying out, then main baseband chip need be waited for after the said mutual completion information with the visit smart card of buffer memory again and send to smart card.
Below with the mutual of SIM be that example describes:
If carry out alternately with SIM, each sends APDU (Application Protocol data unit, Application Protocol Data Unit) according to the agreement of standard SIM card to main baseband chip from baseband chip and comes to carry out alternately with SIM.Wherein, the APDU of one whole comprises the command response that one or more the TPDU to smart card (Transport Protocol Data Unit, TPDU) order and smart card returns alternately.
Go forward side by side behind the row cache when main baseband chip receives certain TPDU that sends from baseband chip X, judge current the mutual of APDU and SIM that whether carrying out:
If current a baseband chip has been arranged (possibly be that other are from baseband chip; Also possibly be main baseband chip) in the middle of the carrying out alternately of the APDU that triggers and SIM, then main baseband chip waits for that the APDU request of selecting a buffer memory after this APDU reciprocal process finishes again continues and SIM carries out alternately.Wherein, the principle of selection can also can be confirmed (priority that is provided with in advance like the user or the like) by the sequencing decision of APDU request by other principle, and the principle of selection can be tactful with reference to above-mentioned several kinds of enumerating.
If in the middle of the carrying out alternately of the APDU that (possibly be other from baseband chip, also possibly be main baseband chip) triggers current neither one baseband chip and SIM, then main baseband chip is directly selected an information transmission of visiting smart card.Wherein, the principle of selection also can be with reference to the above-mentioned several kinds of strategies of enumerating.In this case, if having only the said TPDU that sends from baseband chip X in the buffer memory, then main baseband chip can directly be transmitted this APDU and ask to SIM.
Because it is mutual that APDU possibly relate to a plurality of TPDU alternately; Therefore in APDU reciprocal process; If main baseband chip receives the APDU request of sending from baseband chip; Or the APDU request that oneself produces the visit SIM, at current a plurality of TPDU mutual (promptly an APDU is mutual) not before the completion, do not allow that to carry out other APDU mutual with this SIM.In brief, be exactly not allow mutual intersection of a plurality of APDU to carry out, can avoid data to obscure like this, but also can improve the efficient mutual with SIM.
In addition, based on content embodiment illustrated in fig. 2, the utility model also provides another preferred embodiment, and is specific as follows:
As previously mentioned, said main baseband chip plays the effect of master control in whole communication process, and it is mutual that main baseband chip can be accomplished own visit with smart card on the one hand, can also transmit other interactive information from baseband chip and smart card on the other hand.In this preferred embodiment, if close the idle function of said main baseband chip, then said main baseband chip can't produce the information of visit smart card; But,, can also be transmitted to said smart card respectively when said main baseband chip receives each after the information of baseband chip visit smart card.That is: after the communication function of said main baseband chip was closed, its forwarding capability can also continue.
Concrete; When said main baseband chip receives a plurality of information from baseband chip visit smart card; Still can be respectively carrying out buffer memory from the information of baseband chip visit smart card, and the information of the visit smart card of buffer memory is transmitted to smart card one by one according to the strategy that presets.Wherein, the said strategy that presets includes but not limited to following several kinds of enumerating:
(1) sequencing according to visit sends one by one;
(2) send one by one according to the priority of business;
(3) priority of setting according to the user is sent one by one;
(4) send one by one according to priority from baseband chip.
When being a plurality of from baseband chip; Can set the priority level of respectively visiting smart card from baseband chip; Said main baseband chip can select the high information from baseband chip visit smart card of priority to send to smart card earlier from buffer memory, and then sends the low information from baseband chip visit smart card of priority.
In conjunction with foregoing, further understand the content of the utility model in order to make those skilled in the art, describe through two object lessons below.
Example 1: a kind of multi-module mobile terminal
The equipment of above-mentioned many baseband chips share and access smart card is applied in the portable terminal, a kind of multi-module mobile terminal can be provided.
With reference to Fig. 3, be the structure chart of the said a kind of multi-module mobile terminal of the utility model embodiment.
Said multi-module mobile terminal comprises two baseband chips, and one is main baseband chip, and another is from baseband chip.In this example, said main baseband chip is TD-LTE BB (hereinafter to be referred as TDL), is mainly used in 4G or 5G business, and said is TD-SCDMA BB (hereinafter to be referred as TDS) from baseband chip, is mainly used in 2G or 3G business.
Said main baseband chip TDL provides two SIM interfaces, and one of them SIM interface (like the USIM Master among the figure) is used for being connected with SIM, and another SIM interface (like the USIMSlaver among the figure) is used for and is connected from baseband chip TDS.
Said multi-module mobile terminal comprises that also one switches switch, and the one of which end is connected with SIM, the other end respectively with main baseband chip TDL be connected from baseband chip TDS.Said diverter switch is used for as main baseband chip TDL with when baseband chip TDS all is in holding state; With self conducting that is connected with main baseband chip TDL; And with self with from the connection closed of baseband chip TDS; Saidly visit said SIM from baseband chip TDS through the forwarding of main baseband chip TDL, said main baseband chip TDL is through diverter switch visit SIM.
Said diverter switch also is used for after closing main baseband chip TDL; Connection closed with self and main baseband chip TDL; And with self and the conducting that is connected from baseband chip TDS; Saidly can directly visit said SIM through diverter switch, need not forwarding, thereby realized single standby through main baseband chip TDL from baseband chip TDS.This single standby is owing to closed main baseband chip TDL, the energy consumption of therefore more saving said multi-module mobile terminal.
In addition, a plurality of if main baseband chip TDL connects simultaneously from baseband chip TDS (not shown Fig. 3), and respectively all be connected with SIM through said diverter switch from baseband chip TDS.In this case; If main baseband chip TDL and a plurality ofly all be in holding state from baseband chip TDS; Then said diverter switch is with self conducting that is connected with main baseband chip TDL; And with self and respectively from the connection closed of baseband chip TDS, respectively all can be through the forwarding visit SIM of main baseband chip TDL from baseband chip TDS.
If close main baseband chip TDL, then said diverter switch is with the connection closed of self and main baseband chip TDL.At this moment, respectively directly visit SIM through diverter switch respectively with switching way from baseband chip TDS.Said switching way is meant: when certain during from baseband chip TDS1 request visit SIM; Said diverter switch is with self conducting that is connected from baseband chip TDS1 with the current accessed SIM; And with self and all the other connection closeds from baseband chip TDS, current request visit SIM just can directly visit SIM through diverter switch from baseband chip TDS1 like this.After the visit from baseband chip TDS1 finishes; If another is from baseband chip TDS2 request visit SIM; Diverter switch can close self with from being connected of baseband chip TDS1, with self and the conducting that is connected, realize from baseband chip TDS2 visit SIM from baseband chip TDS2.
Said multi-module mobile terminal also comprises an application processor; Respectively with said main baseband chip TDL be connected from baseband chip TDS; Be used for transmitting control signal to said main baseband chip TDL with from baseband chip TDS respectively, like startup and shutdown signal, single standby signal, two standby signals or the like.In this example, said application processor and main baseband chip TDL with can adopt USB interface from being connected of baseband chip TDS, also can adopt the SDIO interface.In addition, said application processor can also be to above-mentioned diverter switch transmitting control commands, and which control its switch connect conducting or close with.
Based on above-mentioned structure shown in Figure 3, said multi-module mobile terminal provides two kinds of mode of operations, and a kind of is dual standby mode, and another kind is single standby mode.When TDL and TDS pair of standby, TDS passes through the TDL transfer to the visit of SIM; When the standby of TDS list, TDS directly carries out the visit of SIM, and TDL is in off-mode.Said two kinds of mode of operations are carried out the switching of pattern by the application processor control its switch.
The process that switches to two standbies is following:
Application processor is all reset TDS and TDL (reset), and analog switch is set is 0;
At first, application processor transmits control signal and starts TDL, and TDL carries out the initialization procedure of SIM;
According to the smart card standard agreement, said initialization procedure relates to the transmission of VCC (voltage signal), CLK (clock signal), RST (reset signal), several kinds of signals of DIO (IO signal), and is as shown in Figure 3;
Then, application processor transmits control signal and starts TDS.
After TDS and TDL start, can carry out many baseband chips share and access SIM according to flow process shown in Figure 2 standby simultaneously.
The process that switches to the single standby of TDS is following:
Application processor is all reset TDS and TDL (reset), and analog switch is set is 1;
Application processor transmits control signal and starts TDS, and TDS carries out the initialization procedure of SIM.
Under the single standby mode of TDS, because TDL is in off-mode, the energy consumption that therefore can save multi-module mobile terminal.
In order to realize above-mentioned dual standby mode, said main baseband chip TDL can comprise master control module and cache module, wherein:
Cache module is used for when main baseband chip produces the information of visit smart card, then the information of the visit smart card of buffer memory master baseband chip generation; Said when baseband chip TDS produces the information of visit smart card when arbitrarily, the information of the said arbitrarily visit smart card that sends from baseband chip of buffer memory then;
The master control module, be used for baseband chip of every completion and smart card mutual after, the information of from said cache module, getting a visit smart card according to the strategy that presets sends to smart card.
As previously mentioned, the said strategy that presets can comprise:
