Description
Technical field
The present invention relates to wireless communication field, particularly the method for processing task conflict of mobile terminal.
Background technology
Mobile communication technology development defines the mobile communications network of multiple types, as the global communication mobile system (GSM in second generation mobile communication system (2G), Global System for Mobile Communication), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA in 3-G (Generation Three mobile communication system) (3G), Time Division-Synchronous CDMA), Long Term Evolution (LTE in next generation mobile communication system, Long Term Evolution) and worldwide interoperability for microwave access (WIMAX, Worldwide Interoperability for Microwave Access).
Because the networking time of each communication network is different, the scope of each network coverage is different, and the application service content that different operators provides and rate also have very big difference.In the process of Communication Development, customer-centric is the focus of market competition.For consumers, it wishes use mobile terminal, by configuring different subscriber identification card (SIM, Subscriber Identity Module, hereinafter referred to as SIM card), to enjoy the application service that different operators on heterogeneous networks provides.Meanwhile, a mobile terminal configuring the service that different SIM card enjoys consolidated network simultaneously is also required for consumer.
For this reason, the mobile terminal of corresponding configurable multiple SIM card also arises at the historic moment, and makes communication become more convenient.Prior art provides the scheme of multiple this technology of support, such as, just discloses a kind of travelling carriage of bimodulus in U.S. Patent Application Publication US2006/0095600A1.Described dual mode mobile station can support two kinds of different mobile communications networks, as GSM, CDMA.Described dual mode mobile station can identify configuration SIM card in a mobile station automatically, and selects corresponding drive pattern.
At present, the mobile terminal meeting multi-card multi-standby requirement mainly contains two types.For double-card dual-standby, a kind of mobile terminal is called as two treats bilateral mobile terminal, and it has two cover baseband processing modules and two cover radio frequency processing modules.Such as, Chinese patent application 200610157647.0 just provides and a kind ofly two subscriber cards can be made to be in the technical scheme of holding state simultaneously, its dual-SIM-card dual-standby mobile terminal provided comprises main frame and from machine, main frame and have separately independently draw-in groove, antenna, baseband processing module and radio frequency processing module respectively from machine.Due to main frame with from machine independence separately, the business of subscriber card in each draw-in groove thus can be processed independently.But this movement due to actual be by two cover communication devices form, therefore cost compare is high, and power consumption is also higher.
Accordingly, another kind of mobile terminal is called as two treats single-pass mobile terminal, and it uses single baseband processing module and injection processing module frequently.Treat bilateral mobile terminal relative to two, twoly treat that the cost of single-pass mobile terminal and power consumption reduce all greatly.But, due to two treat single-pass mobile terminal actual be by two SIM card shared baseband processing modules and radio frequency processing module to carry out Business Processing, namely, therefore inevitably there is the problem of task conflict in two cover protocol stack, a set of physical layer processing unit.
Such as, treat that single-pass mobile terminal exists following applicable cases usually for described pair: in order to initiating communication business or paging receiving information, need one of selected current SIM card (being set to SIM1) suitable community to carry out resident after start, this just needs physical layer processing unit to perform frequency point scanning and Cell searching task (being called " task one ").But owing to not operating an other SIM card (being set to SIM2), SIM2 should not be affected.When mobile terminal is resident behind Serving cell, SIM2 place, in order to receive the calling of other mobile terminals or fixed station, in each Page Indication Channel (PICH) cycle, all need to perform Page Indication Channel (PICH) in Serving cell and receive task (being called " task two "), to guarantee the paging information not losing network transmission.Like this, just there is conflicting between the task one of SIM1 and the task two of SIM2.
When conflicting with task two for described task one, the processing mode of current existence is the task abandoned wherein, that is:
(1) abandon task one and go to execute the task two, after task two completes, re-execute task one again;
(2) abandon this task two, after task one completes and returns IDLE state, wait for that next PICH executes the task two when arriving.
In two kinds of processing modes of conflicting with task two in above-mentioned solution task one, no matter be first kind of way or the second way, always need to abandon a certain task.This is for mobile terminal, have impact on the process of task process.
Summary of the invention
The problem that the present invention solves is to provide a kind of method for processing task conflict of mobile terminal, to accelerate task treatment progress, optimizes the use of physical layer processing unit.
For solving the problem, the invention provides a kind of method for processing task conflict of mobile terminal, comprising:
In current executory task and pending task conflict, and pending task priority higher than current executory task time, judge that whether current executory task identical with the operation frequency of pending task;
If current executory task is identical with the operation frequency of pending task, then judge whether to obtain pending required by task signal the signal that can receive from current executory task;
If obtain pending required by task signal the signal that can receive from current executory task, obtain described pending required by task signal, to perform described pending task and described current executory task respectively.
Compared with prior art, such scheme has the following advantages: when facing task conflict, for can the situation (two Conflict Tasks frequencies are identical and pending required by task signal can be obtained from current executory task received signal) of parallel processing task, after pending required by task signal acquisition, perform two Conflict Tasks respectively again, make two Conflict Tasks can share a set of physical layer processing unit in mobile terminal, when performing current executory task, also take into account the process of pending task.Thus, accelerate the process of task process.
And for cannot the situation of parallel processing task, take the mode of pending priority of task process, for current executory task also by suspending and preserving task process parameter, give the follow-up possibility continuing to perform.Thus the implementation abandoned relative to prior art and restart mission, can reduce the time that current executory task finally completes, also accelerate the process of task process.

Embodiment
As previously mentioned, prior art, when processing above-mentioned Cell searching task and Page Indication Channel receives task conflict, always needs to abandon a certain task, thus have impact on the process of mobile terminal task process.The present invention this is proposed for solution, to optimize the process of task process.Fig. 1 shows a kind of execution mode flow chart of the method for processing task conflict of mobile terminal of the present invention.Described method for processing task conflict comprises:
Perform step s1, when current executory task and pending task conflict, determine that pending task priority is higher than current executory task;
Perform step s2, judge that whether current executory task is identical with the operation frequency of pending task; If identical, then forward step s3 to; If different, then forward step s6 to;
Perform step s3, judge whether to obtain pending required by task signal the signal that can receive from current executory task; If can, then forward step s4 to; If can not, then forward step s7 to;
Perform step s4, obtain described pending required by task signal to perform described pending task;
Perform step s5, perform described current executory task;
Perform step s6, suspend current executory task and preserve task process parameter;
Perform step s7, suspend current executory task and preserve task process parameter;
Perform step s8, after step s6 or step s7 completes, perform pending task.
In above-mentioned execution mode, when facing task conflict, first whether identical for the operation frequency of two tasks clashed, and obtain pending required by task signal the signal that whether can receive from current executory task and judge.
Identical and when obtaining pending required by task signal the signal that can receive from current executory task, obtain pending required by task signal at operation frequency.Execute the task owing to treating, mobile terminal obtains desired signal, thus next can continue in the terminal to process pending task, and without the need to taking the radio frequency processing module of mobile terminal again.Like this, to current executory task, mobile terminal also can continue to utilize radio frequency processing module to obtain coherent signal from network, and follow-up continuation in this locality processes current executory task.Thus mobile terminal achieves and performs current executory task and pending task respectively.
When the required by task signal that operation frequency signal acquisition that is different or that can not receive from current executory task is pending, first suspend current executory task and preserve task process parameter, performing pending task subsequently.Although due to the now pending task of first row relax, but the process for current executory task suspends and preserves task process parameter, after pending task process completes, still can continue the current executory task of process according to the task process parameter of having preserved.
By analyzing above and can learning, above-mentioned execution mode is when facing task conflict, for can the situation (two Conflict Tasks frequencies are identical and pending required by task signal can be obtained from current executory task received signal) of parallel processing task, after pending required by task signal acquisition, perform two Conflict Tasks respectively again, make two Conflict Tasks can share a set of physical layer processing unit in mobile terminal, and when performing current executory task, also taken into account the process of pending task.Thus, avoid the treatment cycle (waiting in such as background technology that next PICH executes the task two when arriving) that prior art needs again to wait for next pending task, accelerate the process of task process.And for cannot the situation of parallel processing task, take the mode of pending priority of task process, for current executory task also by suspending and preserving task process parameter, give the follow-up possibility continuing to perform.Thus, the implementation abandoned relative to prior art and restart mission (is abandoned task one and is gone to execute the task two in such as background technology, task one is re-executed again) after task two completes, the time that current executory task finally completes can be reduced, also accelerate the process of task process.
Below for double-card mobile terminal, the example specifically processing Cell searching task and Page Indication Channel by further illustrates method for processing task conflict of the present invention.It should be noted that, present invention focuses on the Coordination Treatment to two Conflict Tasks, therefore be not limited to the particular type of Conflict Tasks, and, the execution of concrete Cell searching task and Page Indication Channel receive the execution not problem to be solved by this invention of task, the specific implementation that prior art Cell searching task and Page Indication Channel receive task is all applicable to the present invention, just repeats no more the specific implementation of Cell searching task and Page Indication Channel reception task herein.In addition, though below with the citing of TD-SCDMA pattern, application of the present invention is not limited to this, and such as, similar tasks clash handle under other patterns such as GSM, WCDMA etc., is also applicable to the present invention.
With reference to shown in Fig. 2, assuming that a certain SIM card (being set to SIM card A) in described double card mode mobile terminal is when performing Cell searching task under TD-SCDMA pattern, under another SIM card (being set to SIM card B) need perform TD-SCDMA pattern, Page Indication Channel receives task, thereby produces the conflict of Cell searching task and Page Indication Channel reception task.According to method for processing task conflict of the present invention, concrete process is as follows:
Perform step s10, in Cell searching tasks carrying, need to perform Page Indication Channel receive task;
Perform step s20, judge that whether the operation frequency that Cell searching task and Page Indication Channel receive task is identical; If identical, then forward step s30 to; If not identical, then forward step s60 to;
Perform step s30, judge whether that obtaining Page Indication Channel in the signal of eating dishes without rice or wine that can receive from Cell searching tasks carrying process receives required by task signal; If can obtain, then forward step s40 to; If can not obtain, then forward step s70 to;
Perform step s40, receive the synchronizing information of task maintenance according to Page Indication Channel, from described signal of eating dishes without rice or wine, obtain Page Indication Channel receive required by task signal, receive task to perform Page Indication Channel;
Perform step s50, continue to perform Cell searching task;
Perform step s60, suspend Cell searching task, preserve the execution phase type before Cell searching task suspension and inter-related task procedure parameter;
Perform step s70, suspend Cell searching task, preserve the execution phase type before Cell searching task suspension and inter-related task procedure parameter;
Perform step s80, after step s60 or step s70 completes, perform Page Indication Channel and receive task.
Wherein, SIM card A is when carrying out Cell searching task, and usual advanced line frequency spot scan, can the multiple frequency of rotation in frequency point scanning course.And SIM card B complete Serving cell resident after, perform Page Indication Channel when receiving task, the dominant frequency point of Serving cell is its operation frequency.When the operation frequency that frequency and the Page Indication Channel of frequency point scanning rotation receives task is consistent, just can think that Cell searching task is identical with the operation frequency that Page Indication Channel receives task.
With reference to Fig. 3, receive required by task signal for obtaining Page Indication Channel in the signal of eating dishes without rice or wine judging whether in step s30 to receive from Cell searching tasks carrying process, it specifically comprises the following steps:
Perform step s310, judge whether Cell searching task is in the frequency point scanning stage; If so, then step s340 is forwarded to; If not, then step s320 is forwarded to;
Perform step s320, judge whether Cell searching task is in searching downlink pilot frequency slot (DwPTS) the position stage; If so, then step s340 is forwarded to; If not, then step s330 is forwarded to;
Perform step s330, whether synchronously judge that Cell searching task and described Page Indication Channel receive task place network; If so, then step s340 is forwarded to; If not, then step s350 is forwarded to;
Perform step s340, determine that obtaining Page Indication Channel the signal of eating dishes without rice or wine that can receive from Cell searching task receives required by task signal;
Perform step s350, determine that obtaining Page Indication Channel the signal of eating dishes without rice or wine that can not receive from Cell searching task receives required by task signal.
Wherein, signal of eating dishes without rice or wine described in refers to the signal that the interface (Uu interface) between mobile subscriber terminal in TD-SCDMA system (UE) and wireless access network (UTRAN) transmits.
Consider under TD-SCDMA pattern, carry out, in frequency point scanning and search DwPTS position process, needing the signal receiving continuous multiple subframe, therefore can obtaining Page Indication Channel from the signal of eating dishes without rice or wine that Cell searching task receives and receive required by task signal.And after the operation of searching for DwPTS position, just can obtain the synchronizing information of Cell searching task place network, so just for judge whether two task place networks synchronously provide necessary requirement.In fact, when frequency is identical, all comprises Page Indication Channel in the signal that Cell searching task receives and receive required by task signal.But, in the two nonsynchronous situations in a network cell, card place, when utilizing the synchronizing information of Page Indication Channel, just cannot determine this intercepts Page Indication Channel and receives required by task signal from which chip (chip), to which chip should terminate again, and therefore just cannot obtain Page Indication Channel and receive required by task signal.
When determining that obtaining Page Indication Channel the signal of eating dishes without rice or wine that can receive from Cell searching task receives required by task signal, just can as described in step s40, Page Indication Channel is received required by task signal (Page Indication Channel receives task and only needs receiving slot 0 signal) to intercept out, continue the described Page Indication Channel of process by mobile terminal baseband processing module in inside and receive task.The synchronizing information that described Page Indication Channel receives task is safeguarded by the baseband processing module in mobile terminal.And do not needed because after this Page Indication Channel receives task the radio frequency processing module taking mobile terminal again, thus just as described in step s50, execution Cell searching task can be continued.
And it is different for operation frequency, or obtain the situation that Page Indication Channel receives required by task signal the signal of eating dishes without rice or wine that can not receive from Cell searching task, required by task signal is received because the signal of eating dishes without rice or wine that cannot be received by Cell searching task obtains Page Indication Channel, thus just need to suspend Cell searching task and receive task to carry out Page Indication Channel, to avoid losing the beep-page message that network sends to SIM card B.And continue to perform Cell searching task to receive at Page Indication Channel after task completes, also needing when suspending, preserving the inter-related task procedure parameter of Cell searching task before suspending.Signal acquisition Page Indication Channel of eating dishes without rice or wine that is different for operation frequency and that can not receive from Cell searching task receives the situation of required by task signal, and the associative operation of described time-out and preservation is also distinguished to some extent, is described in detail as follows:
With reference to shown in Fig. 4, when operating frequency and being different, suspend Cell searching task, the execution phase type before preservation Cell searching task suspension and inter-related task procedure parameter comprise:
Perform step s610, suspend Cell searching task;
Perform step s620, judge whether Cell searching task is in the frequency point scanning stage; If so, then step s621 is forwarded to; If not, then step s630 is forwarded to;
Perform step s621, preserve Cell searching tasks execution phases type and scanned frequency and corresponding received signal strength indicator (RSSI, Received Signal Strength Indication) thereof, and forwarding step s80 to;
Perform step s630, judge whether Cell searching task is in the searching downlink pilot frequency slot position stage; If so, then step s631 is forwarded to; If not, then step s640 is forwarded to;
Perform step s631, preserve Cell searching tasks execution phases type and frequency point scanning stage all frequencies and corresponding received signal strength indicator thereof, and forward step s80 to;
Perform step s640, judge whether Cell searching task is in and confirm descending synchronous code (Sync-DL code) stage; If so, then step s641 is forwarded to; If not, then step s650 is forwarded to;
Perform step s641, the descending pilot frequency time slot position that preservation Cell searching tasks execution phases type and searching downlink pilot frequency slot position stage obtain, and forward step s80 to;
Perform step s650, judge whether Cell searching task is in and confirm basic training sequences (Midamble code) stage; If so, then step s651 is forwarded to; If not, then step s660 is forwarded to;
Perform step s651, preserve Cell searching tasks execution phases type and confirm the descending synchronous code that the descending synchronous code stage obtains, and forward step s80 to;
Perform step s660, judge whether Cell searching task is in broadcast channel (BCH) decode phase; If so, then step s661 is forwarded to; If not, then step s80 is forwarded to;
Perform step s661, the basic training sequences that preservation Cell searching tasks execution phases type and confirmation basic training sequences stage obtain, frequency offset information between UE and network, and forward step s80 to.
Wherein, be not in above-mentioned all stage type in Cell searching task, illustrate that Cell searching completes, can transfer to perform Page Indication Channel and receive task.
In addition, the Cell searching tasks execution phases type in above-mentioned each stage can be represented by state machine.
With reference to shown in Fig. 5, when the signal acquisition Page Indication Channel of eating dishes without rice or wine that can not receive from Cell searching task receives required by task signal, suspend Cell searching task, the execution phase type before preservation Cell searching task suspension and inter-related task procedure parameter comprise:
Perform step s710, suspend Cell searching task;
Perform step s720, judge whether Cell searching task is in and confirm the descending synchronous code stage; If so, then step s721 is forwarded to; If not, then step s730 is forwarded to;
Perform step s721, the descending pilot frequency time slot position that preservation Cell searching tasks execution phases type and searching downlink pilot frequency slot position stage obtain, and forward step s80 to;
Perform step s730, judge whether Cell searching task is in and confirm the basic training sequences stage; If so, then step s731 is forwarded to; If not, then step s740 is forwarded to;
Perform step s731, preserve Cell searching tasks execution phases type and confirm the descending synchronous code that the descending synchronous code stage obtains, and forward step s80 to;
Perform step s740, judge whether Cell searching task is in broadcast channel (BCH) decode phase; If so, then step s741 is forwarded to;
Perform step s741, the basic training sequences that preservation Cell searching tasks execution phases type and confirmation basic training sequences stage obtain, frequency offset information between UE and network, and forward step s80 to.
Due to when judging whether that obtaining Page Indication Channel the signal of eating dishes without rice or wine that can receive from Cell searching task receives required by task signal, carry out the judgement in frequency point scanning stage and searching downlink pilot frequency slot position stage, therefore when determining that obtaining Page Indication Channel the signal of eating dishes without rice or wine that can not receive from Cell searching task receives required by task signal, just without the need to carrying out the judgement in frequency point scanning stage and searching downlink pilot frequency slot position stage, and can directly from judging whether Cell searching task is in the confirmation descending synchronous code stage.Similarly, the Cell searching tasks execution phases type in above-mentioned each stage is also represented by state machine.The judgement in above-mentioned Cell searching task each stage can be determined by detecting the acquired coherent signal of mobile terminal.
Consider in practical operation, the beep-page message that network sends might not belong to SIM card B, thus whether belongs to SIM card B according to beep-page message, also can after execution Page Indication Channel reception task, be further processed, to optimize task treatment progress further.
With reference to shown in Fig. 6, after execution Page Indication Channel reception task, also can according to beep-page message for the difference of object, respective handling is carried out for Cell searching task, it comprises the following steps:
Perform step s81, to the signal decoding obtained in Page Indication Channel reception task;
Perform step s82, according to decoded result, judge whether to there is the paging to described mobile phone users (SIM card B); If so, then step s83 is forwarded to; If not, then step s85 is forwarded to;
Perform step s83, calculate the time interval between described Page Indication Channel and corresponding paging channel;
Perform step s84, within the described time interval, according to the inter-related task procedure parameter of preserved Cell searching task, continue to perform Cell searching task;
Perform step s85, according to the inter-related task procedure parameter of preserved Cell searching task, continue to perform Cell searching task until complete;
Perform step s86, at the end of judging the time interval, whether Cell searching task completes; If so, then step s87 is forwarded to; If not, then step s88 is forwarded to;
Perform step s87, obtain beep-page message from described corresponding paging channel;
Perform step s88, abandon Cell searching task.
Wherein, existence is judged whether to the paging of described mobile phone users (SIM card B) by judging that paging instruction (PI) information of self correspondence of the UE calculated by high level obtained from Page Indication Channel is determined.
If there is not the paging belonging to SIM card B, time then before next Page Indication Channel arrives, can be used for continuing to perform the Cell searching task suspended, thus as described in step s85, according to the inter-related task procedure parameter of preserved Cell searching task, continue to perform Cell searching task until complete.As previously mentioned, due to when suspending Cell searching task, save the Cell searching tasks execution phases type before time-out and inter-related task procedure parameter, now just can determine the stage also do not performed according to the Cell searching tasks execution phases type before time-out, and continue to perform these stages when Page Indication Channel reception task receives and returns.
If there is the paging to SIM card B, owing to there is certain hour interval between Page Indication Channel and corresponding paging channel, thus can consider to utilize and continue Cell searching task during this period of time, to accelerate task treatment progress further.Calculating time interval between described Page Indication Channel and corresponding paging channel can be obtained by the number of sub frames calculated between Page Indication Channel and corresponding paging channel, and described number of sub frames can according to 8.3 saving the algorithm provided and calculate in 3GPP TS25.304.
At the end of the described time interval, if Cell searching task completes, then can start to obtain beep-page message from described corresponding paging channel, to start to process the paging to SIM card B.If Cell searching task remains unfulfilled, owing to cannot confirm when the business that the beep-page message that SIM card B receives triggers terminates, then abandon Cell searching task, discharge the relevant parameter of the Cell searching task of having preserved.
Can be learnt by the explanation of above-described embodiment, in the process of task clash handle, fully take into account Page Indication Channel and received the enforcement of task (signal of eating dishes without rice or wine of Cell searching task can obtain desired signal, obtains after desired signal and performs; Operation frequency signal of eating dishes without rice or wine that is different or Cell searching task cannot obtain desired signal, and the preferential Page Indication Channel that performs receives task), thus can avoid losing the beep-page message that network sends to SIM card B.And during this period, (signal of eating dishes without rice or wine of Cell searching task can obtain desired signal, performs Cell searching task and Page Indication Channel task respectively also to ensure that it completes as early as possible as best one can for Cell searching task; There is not the paging to SIM card B, continue to perform Cell searching task until complete; The time interval of Page Indication Channel and paging channel is utilized to continue to perform Cell searching task).And the completing as early as possible of Cell searching task, decrease the task processing time on the one hand, also make SIM card A can complete community as early as possible on the other hand resident, also and then decrease the probability of SIM card A calling information drop-out.
It should be noted that, though above with the task conflict citing that double-card mobile terminal relates to, but application of the present invention is not limited to double card, for the mobile terminal comprising double card, three cards or four cards, there is priority height relating to current executory task and pending task, and during situation about clashing, the present invention is all applicable.
Disclosed above many aspects of the present invention and execution mode, it will be understood by those skilled in the art that other side of the present invention and execution mode.Many aspects disclosed in the present invention and execution mode are just for illustrating, be not limitation of the invention, real protection range of the present invention and spirit should be as the criterion with claims.
