Embodiment
The smart card mobile phone that the present invention is applicable and all for simplicity, adopts GSM mobile handset to describe as embodiment, is not limited only to GSM.
Traditional GSM mobile handset hardware block diagram comprises radio-frequency module (RF), baseband chip, peripheral hardware, sim card slot as shown in Figure 2.Baseband chip links to each other with radio-frequency module by radio frequency interface, links to each other with peripheral hardware by Peripheral Interfaces such as keyboard/LCD, links to each other with sim card slot by the SIM interface.Baseband chip also comprises baseband processing module, communication protocol processing module and MMI module.
The double card double standby mobile phone that employing one cover communication device of the present invention is realized is referring to the hardware block diagram of Fig. 3, comprise radio-frequency module (RF), baseband chip, peripheral hardware, two sim card slot SIM1 and SIM2, and electronic switch, baseband chip links to each other with radio-frequency module by radio frequency interface, link to each other with peripheral hardware by Peripheral Interfaces such as keyboard/LCD, baseband chip also has SIM interface and sheet modeling piece, links to each other with electronic switch, and the other end of electronic switch links to each other with two sim card slots.
Described baseband chip also comprises baseband processing module, base band time division multiplexing module, SIM card communication protocol processing module, MMI module and SIM interface time division multiplexing module except comprising above-mentioned Peripheral Interface, radio frequency interface, SIM card interface and sheet modeling piece.Wherein said SIM card communication protocol processing module comprises SIM1 communication protocol processing module and SIM2 communication protocol processing module.
SIM1 communication protocol processing module and SIM2 communication protocol processing module are shared the SIM interface by SIM interface time division multiplexing module, and SIM interface time division multiplexing module is controlled electronic switch to select the SIM card of required read-write by sheet modeling piece.When SIM1 communication protocol processing module need to be read and write SIM1, SIM interface time division multiplexing module was the service of SIM1 communication protocol processing module, by sheet modeling piece control electronic switch, connected SIM1; When SIM2 communication protocol processing module need to be read and write SIM2, SIM interface time division multiplexing module was the service of SIM2 communication protocol processing module, by sheet modeling piece control electronic switch, connected SIM2.When generation SIM1 communication protocol processing module and SIM2 communication protocol processing module asked to read and write SIM card simultaneously, SIM interface time division multiplexing module arrangement one tunnel was read and write another road and is waited for that a dataway operation is finished, and another road is read and write.Because read-write SIM task amount is very little, so this kind method is feasible.
SIM1 communication protocol processing module and SIM2 communication protocol processing module are shared baseband processing module by base band time division multiplexing module, when SIM1 communication protocol processing module need to be passed through the baseband processing module transceiving data, base band time division multiplexing module is the service of SIM1 communication protocol processing module, when SIM2 communication protocol processing module needs transceiving data, base band time division multiplexing module is the service of SIM1 communication protocol processing module, when two-way clashes, base band time division multiplexing module guarantees one tunnel data transmit-receive, another road then is equivalent to enter the dead space, by the time be that one tunnel service is complete, provide service for another road again.
In the time division multiplexing mobile communication system, in general, the two-way transceiving data can not conflict basically under holding state, and under service condition, the SIM that is in service condition takies baseband processing module, and another road can't be received and dispatched.If the two-way transceiving data clashes, then be equivalent to another road and enter the dead space.For the general user, this is complete acceptable.Analyze as an example of GSM example at this: among the GSM, mobile phone needs every 470.73ms to remove to receive paging data one time to 2118.3ms under the holding state, the time that the paging receiving data need to take baseband processing module is 18.46ms, the situation of two-way conflict possibility occurrence maximum is all paging datas of every 470.73ms reception of two-way, and the probability that clashes in such cases is: 18.46*2/470.73=7.84%.If a phone arrives, network sends paging and will continue for some time, and can reduce the probability that Inbound Calls is lost by the mode that alternately receives, and irrelevant with the present invention, this paper no longer carefully states; The SIM that is in service condition under the service condition takies baseband processing module, and another road can't be received and dispatched, and per hour converses 5 minutes by the traffic carrying capacity of domestic consumer, i.e. 1/12 Ireland, the probability that conflict occurs is: 1/12=8.33% for domestic consumer, is complete acceptable.
The switching of electronic switch control SIM card, between transfer period, electronic switch just disconnects wherein two pins of I/O, CLK of a SIM card, and connects simultaneously two pins of I/O, CLK of an other SIM card, and the VSIM of SIM card, RST, GND, VPP does not disconnect during switching SIM card, so, during switching SIM card, the SIM card that just is disconnected can not be carried out read-write operation, can read and write this SIM card again after waiting switchback.
When processing the double card business, being business-driven, is the method for operation of preemptive type, and what specifically seize is I/O and two hardware resources of CLK of SIM, by the switching of electronic switch according to business demand control SIM card.
Access to SIM card is driven by concrete business, and business comprises read-write SIM file and carry out SIM authentication etc. that arbitrary calorie requirement work then electronic switch is cut over first, then operates.To operate simultaneously if there is two cards, then control the alternative that guarantees two card access by software, wait one to block the operation of carrying out again another card after operation is finished.
Because it is sporadic that the signal that receives from network side all has, the processing that therefore can carry out signal at same hardware is feasible.If there is conflict, then can priority treatment receive first.The processing logic of single chip double card with the logical construction difference of two cover chips is: conflicting on if there is no signal sends and receives, then two cards all processes, if the conflict on life period and the hardware resource, the then request that arrives first of priority treatment, then delay processing (such as the access of SIM card) for what can delay processing, for delaying processing, discard request (as receiving the network signal on the assigned timeslot) then.
Single cover communication device double-card mobile phone that the present invention speaks of is not limited only to GSM mobile handset, in a broad sense, as long as smart card can be according to doing like this, comprises that GSM SIM card, CDMA card, WCDMA, TD-SCDMA card all can so realize.
According to the present invention, can on the basis of existing single cover communication device, realize double-card dual-standby.Satisfied greatly the user and used the strange land even numbers, enjoyed simultaneously the demand of two different operators services, the mobile phone volume is little, and cost is low, and is easy to carry.
