Embodiment
See also Fig. 3, this is an embodiment of the application's single-chip multi-card multi-standby mobile phone.Subscriber identification module wherein is take SIM card as example, and user's identification controller is take the SIM controller as example, SIM card and SIM controller all take four as example, according to the type of subscriber identification module and the different corresponding modify of carrying out of quantity.Single-chip multi-card multi-standby mobile phone shown in Figure 3 comprises: display, keyboard, antenna, baseband processing chip, four sim card slots and other peripheral hardwares.Described display and keyboard are also replaceable to be touch-screen.Integrated baseband processor (not shown) and memory module (not shown) in baseband processing chip, also integrated one or more in broadcast receiver, audio frequency amplifier, radio-frequency module, power management module, the bluetooth module have also encapsulated exterior storage medium.Described power management module has Switching Power Supply and two kinds of mode of operations of linear power supply, and can select mode of operation by baseband processor.Described exterior storage medium is such as being flash, psram(pseudo-static random access memory) etc.In baseband processing chip, also be integrated with four SIM controllers.Except SIM controller and sim card slot are many covers of equal number, all the other each modules all only have a cover.Four SIM controllers respectively connect a sim card slot and this annexation and will not remain and disconnect.Baseband processor only connects user's identification controller at one time, realizes thus the selection to many cards.
Compare with single chip dual-card dual-standby mobile telephone shown in Figure 1, the application has two places to improve at hardware configuration:
One, in the application's the single-chip multi-card multi-standby mobile phone, being connected between each user's identification controller and each subscriber identification module do not remaining and disconnecting.Even during the process of switching subscriber identification module, each pin of a plurality of subscriber identification modules can not carried out opening operation (unless some pin is exactly to disconnect originally) yet.So, the application's single-chip multi-card multi-standby mobile phone be by baseband processor to the alternative annexation between a plurality of user's identification controllers, realize the switching of a plurality of subscriber identification modules.That is: the application adopts software mode to switch many cards, and adopt hardware (electronic switch) mode to switch many cards with patent A and compare, can reduce power consumption thereby not only can omit hardware, and also more reliable on electric property, be not easy to make mistakes.
Its two, integrated alternatively broadcast receiver, audio frequency amplifier, radio-frequency module, power management module, bluetooth module have also encapsulated exterior storage medium alternatively in the baseband processing chip.Space and manufacturing cost in the machine have obviously been saved in the work of this integrated and encapsulation, but also so that the distance between each module furthered, this can bring each other and and baseband processor between interference problem, also may make noise become large.The application has successfully overcome interference and noise problem by the clock frequency of adjusting modules and/or the electric source modes of mobile phone.
For example, radio receiver module is when work, process if baseband processing chip carries out signal to baseband signal, the latter will bring interference at specific frequency to the former frequency modulation (FM) radio reception, can adopt one of following two kinds of settling modes or Integrated using so:
(1) working clock frequency of adjusting baseband processor normally reduces working clock frequency.Lap between the energy of the harmonic energy that produces when processing baseband signal of baseband processor and the radio receiver module broadcast singal that receives specific frequency will reduce like this, thus reduce disturbance and noise.
(2) power management module has characteristics low in energy consumption, that noise is large under the mode of operation of Switching Power Supply, has the characteristics that power consumption is high, noise is little under the mode of operation of linear power supply.Thereby in order to reduce noise, the power supply of mobile phone can also be changed into the mode of operation of linear power supply by Switching Power Supply.
See also Fig. 4, the handled business of single-chip multi-card multi-standby mobile phone is broadly divided into three classes: to mutual, the multimedia application of read-write, mobile phone and the base station of subscriber identification module File.The interactive service of described mobile phone and base station is subdivided into again and sends professional and the reception business.Describedly send professional business when referring to that mobile phone need to be with network communication.The professional business that refers to mobile phone receiving system message, beep-page message etc. of described reception.The application only relates to the multi-card multi-standby single-pass mobile phone of single-chip, thereby the business that a plurality of subscriber identification module may clash only has the read-write subscriber identification module and receives professional two classes.
In the application's single-chip multi-card multi-standby mobile phone, although it is a plurality of that user's identification controller and draw-in groove all have, but baseband processor only has one, thereby when processing a plurality of subscriber identification modules of read-write professional, may produce competition to baseband processor, this application is provided following contention resolution:
(1) the application's single-chip multi-card multi-standby mobile phone is to process like this for the business of read-write subscriber identification module:
A, arbitrary service needed read-write subscriber identification module then send request to baseband processor;
B, baseband processor connect corresponding user's identification controller according to described service selection, and send the instruction of described business to this user's identification controller;
C, described user's identification controller are carried out described instruction to the subscriber identification module that is connecting, and will deposit in the internal memory the execution result of described instruction and read for baseband processor.
(2) when a plurality of service needed read-write subscriber identification modules, baseband processor connects successively corresponding user's identification controller and sends service order to it according to receiving professional sequencing.This shows, above-mentioned a step can not parallel processing, can only be sequential processes.
(3) baseband processor can only connect at one time user's identification controller and send service order to it, baseband processor disconnects and being connected of this user's identification controller after service order is sent, and then according to the corresponding subscriber identification module of next service connection and to its transmission service order.This shows, has exclusiveness between the b step of different business, can not parallel processing.
(4) arbitrary user's identification controller is carried out described instruction to the subscriber identification module that is connecting and the result is deposited in the internal memory, does not affect to carry out instruction between other user's identification controllers and the subscriber identification module that is being connected separately and the result is deposited in the internal memory.This shows, above-mentioned c step does not have exclusiveness, and the c step of different business can parallel processing.
(5) baseband processor connects user's identification controller and sends service order to it, deposits in the internal memory to subscriber identification module execution instruction and with the result with other user's identification controllers, is independent of each other.This shows, can parallel processing between the b step of different business and the c step.
Further, all professional read-write subscriber identification modules all have the maximum duration restriction, send service order from baseband processor to user's identification controller and begin timing.Restriction is not disposed yet if a certain business exceeds maximum duration, and baseband processor will will should business be processed again, is to send the service order from baseband processor to user's identification controller yet.Again processing has the number of times restriction, for example is 3 times.Exceed the number of times restriction of again processing, then baseband processor stops to process this business, and sends error message to this professional requesting party.
Sometimes, why the business of read-write subscriber identification module exceeds maximum duration restriction, is because the data that read according to the rising edge (or trailing edge) of clock signal are incorrect, this may since clock signal cause.Therefore when again processing overtime business, all clock signal is offset at every turn.If clock signal skew 100% just is equivalent to not change, preferred side-play amount is 50%, 25%, 75%.By again processing overtime business all is offset clock signal different amounts at every turn, so that the success rate of the business of read-write subscriber identification module is greatly improved.
The application compares with patent A for the conflict processing method of the many cards of read-write, has following advantage:
One adopts software mode to realize that many cards switch, and has omitted many cards switching construction of hardware, has reduced thus cost, has reduced power consumption.
Its two, only have between b step and the b step and have exclusiveness, simultaneously parallel processing.Between c step and the c step, all do not have exclusiveness between b step and the c step, simultaneously parallel processing.The step that this method will have exclusiveness is reduced to a minimum, and step that can parallel processing is increased at most, thereby has realized to greatest extent the highest treatment effeciency and processing speed.
For example, a single chip dual-card dual-standby mobile telephone can insert a SIM card and a UIM card simultaneously.Professional m request file of read-write in SIM card proposes to baseband processor first.Professional n request writes a file in the UIM card, backward baseband processor proposes.
Processing method according to patent A, professional m is owing to proposing first, thereby electronic switch is connected first I/O and two pins of CLK of SIM card, and the respective pin of disconnection UIM card (supposing that patent A also supports the UIM card), then send the instruction of professional m to the SIM interface, the SIM interface is carried out read operation to SIM card, and reading result is stored in the internal memory.Subsequently, electronic switch responds the professional n of rear proposition again, connects the pin of UIM card and disconnects the pin of SIM card, the instruction of then sending professional n to the UIM interface, the UIM interface is carried out write operation from the internal memory reading out data to the UIM card, and will write the result and be stored in the internal memory.
And according to the application's processing method, professional m is owing to proposing first, thereby baseband processor connects first the SIM controller and sends the instruction (the b step of professional m) of professional m to it.Baseband processor connects the UIM controller again and sends the instruction (the b step of professional n) of professional n to it subsequently, meanwhile the SIM controller is carried out read operation and reading result is stored in (the c step of professional m) in the internal memory SIM card, and both are independent of each other and carry out simultaneously.SIM card being carried out read operation and reading result is stored in (the c step of professional m) in the internal memory, the UIM card is carried out write operation and will be write the result from the internal memory reading out data with the UIM controller and be stored in (the c step of professional n) the internal memory at the SIM controller, also is to be independent of each other to carry out simultaneously between the two.
Its three, by means such as timers maximum duration restriction is set, guarantee when professional make mistakes or the situation of subscriber identification module fault under, calling party identification module unrestrictedly not.
In the application's single-chip multi-card multi-standby mobile phone, although it is a plurality of that user's identification controller and draw-in groove all have, but baseband processor, radio-frequency module, antenna all only have one, thereby when the reception of processing a plurality of subscriber identification modules is professional, may produce competition to these hardware resources, this application is provided following contention resolution:
(1) a plurality of subscriber identification modules calculate the time point of network terminal transmitting system message, beep-page message in advance according to the frame synchronization information of the residential quarter that enters, thereby learn in advance when a plurality of subscriber identification modules which kind of can occur and receive operational conflict.Take the GSM network as example, in a single day the application's single-chip multi-card multi-standby mobile phone enters into a residential quarter (cell), will receive the frame synchronization information (tdma frame) in this residential quarter, and mobile phone just can calculate network terminal and send out what message when.
The operational conflict of described reception can be divided three classes:
The first kind: when each subscriber identification module all receives individual system message or during the equal paging receiving message of each subscriber identification module or the subscriber identification module that has receive individual system message and during other subscriber identification module paging receiving message, the conflict of time of reception point occur;
Equations of The Second Kind: the subscriber identification module that has receives continuous system message and other subscriber identification modules when receiving individual system message or beep-page message, and the conflict of time of reception point occurs,
The 3rd class: when plural subscriber identification module all receives continuous system message, the conflict of time of reception point occurs.
(2) for first kind conflict, select at random one of them subscriber identification module to receive business, the reception of abandoning all the other subscriber identification modules is professional.Because all being circulations, the individual system message that the base station sends to mobile phone, beep-page message etc. send, not selected subscriber identification module will receive when individual system message or beep-page message repeat to send again, if also have when the time comes conflict then still process by the described method of the application.
(3) for the Equations of The Second Kind conflict, select subscriber identification module to receive continuous system message, the reception of abandoning all the other subscriber identification modules is professional.Continuous system message is corresponding cell reselection operation usually, may not cause corresponding subscriber identification module to fall net if do not process immediately, thereby must priority treatment.And individual system message, beep-page message repeat to send, and not selected subscriber identification module will receive when individual system message or beep-page message repeat to send again, if also have when the time comes conflict then still process by the described method of the application.
Further, for the 3rd class conflict, according to the priority of calculating in advance the continuous system message that will receive of learning, select subscriber identification module to receive continuous the preceding system message according to baseband processor, the reception of abandoning all the other subscriber identification modules is professional.Because baseband processor only has one, even a plurality of subscriber identification module all will receive continuous system message, baseband processor also must have sequencing when processing the reception business so.This set is not absolute, can select the continuous system message after subscriber identification module is received in yet, and the reception of abandoning all the other subscriber identification modules is professional, and is as broad as long on effect.
The application compares with patent B for the conflict processing method of the reception business of processing many cards, has following advantage:
One adopts the random mode of selecting for first kind conflict, thoroughly stopped the described scheme of patent B and may cause a SIM card wherein to face the hidden danger of cell reselection.
For example in certain residential quarter, network terminal sends individual system message to terminal every 8 chronomeres, and every 2 or 4 chronomeres' transmission beep-page messages, terminal has two subscriber identification module first, second.At this moment, the time point that first receives individual system message is with after the time point generation of second paging receiving message once conflicts, and this collision scenario will occur repeatedly continuously.According to the application's scheme, will between first, second, select at random one when conflicting for the first time and process the business of reception, it is professional that each conflict afterwards all will select a processing to receive between first, second at random.From probability, first, second all has the chance that is selected about equally, thereby after the conflict of continuous several times, the reception that both Parties all can be processed separately is professional, the awkward situation that one of them subscriber identification module faces cell reselection can not occur.So also stop simultaneously the mobile phone off-line in this type of situation, and correspondingly reduced mobile phone power consumption.
Its two, a plurality of subscriber identification modules are no longer distinguished major-minor, perhaps select at random (first kind conflict), perhaps select (Equations of The Second Kind conflict) according to the significance level of business, perhaps select (the 3rd class conflict) according to the priority of message, fairer and more reasonable.
See also Fig. 5, this is the Software Protocol Stack of the application's single-chip multi-card multi-standby mobile phone.It is example with two SIM cards and two SIM controllers, according to the type of subscriber identification module and the different corresponding modify of carrying out of quantity.It is seven layers that whole Software Protocol Stack is divided into from bottom to top, is respectively: physical layer, physical control layer arbitration modules (L1 common), physical layer key-course (L1), data link layer, network layer, transport layer, application layer.Two SIM cards share physical layer, physical control layer arbitration modules, data link layer and application layer, but have separately independently physical layer key-course, network layer and transport layer.
Compare with single chip dual-card dual-standby mobile telephone shown in Figure 2, the improvement of the application on Software Protocol Stack is mainly manifested in: two SIM cards share physical layer, but independently physical layer key-course is arranged.Share physical layer, can reduce size of code, be convenient to software administration.Two physical layer key-courses independently are to control according to the arbitration of physical control layer arbitration modules the resource of the physical layer that shares is used.Described physical control layer arbitration modules does not exist on hardware, is according to the performed arbitration function of baseband processor and an independent software module.
The described single-chip multi-card multi-standby mobile phone of the application not only is confined to SIM card, also can be used for UIM card, usim card etc., and correspondingly mobile communication network can be GSM, CDMA, WCDMA, CDMA2000, TD-SCDMA etc.
Be the application's preferred embodiment only below, and be not used in restriction the application.For a person skilled in the art, the application can have various modifications and variations.All within the application's spirit and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the application's the protection range.
