Description
Technical field
The present invention relates to mobile communication equipment, especially dual-mode handset.
Background technology
Because dual-mode handset can make mobile phone can obtain the mobile communication signal in the mobile communications network of two kinds of different frame lengths, therefore, though when the mobile communications network of pattern one does not cover the mobile phone position or mobile phone can't provide talk channel in the mobile communications network scope of pattern one but because the mobile communications network of pattern one is busy the time, can also seek the support of the mobile communications network signal of pattern two.This has enlarged the scope that dual-mode handset and similar mobile device are accepted service in undoubtedly, and therefore, dual-mode handset more and more is subjected to liking of user, and the developer has also increased the research work to dual-mode handset gradually.
Can not research and develop the needed all component of dual-mode handset, agreement etc. because the R﹠D cycle is short with growing out of nothing, thereby and research and develop all component and agreement with growing out of nothing and also caused a large amount of wastes of prior art not need the such management development work of mobile device developer.Therefore, at the development dual-mode handset, for example adopt WCDMA (Wideband Code Division Multiple Access (WCDMA))/GSM (global system for mobile communications, Global System for Mobile Communications) dual-mode handset of two kinds of patterns, perhaps in the process of GSM/IS95 (Interim Standards) dual-mode handset, many mobile device developers start all over again from the beginning fully.The developer more wishes farthest to utilize the technical scheme of existing mobile communication equipment, revise prior art by trying one's best littlely and make the prior art scheme to be applied in the dual-mode handset, and in fact the technical staff also adopts really and develops dual-mode handset in such a way constantly.
The research and development dual-mode handset also has reason on the other hand on the prior art basis, promptly because existing mobile communication technology scheme has dropped into a large amount of infrastructure investments, therefore, also be necessary under the prior art scheme, to develop dual-mode handset,, new dual-mode handset utilizes to bigization existing infrastructure, for example communication network so that can trying one's best.
Those skilled in the art can understand, and utilize existing two kinds of different technical schemes, just needs to solve the clock synchronization issue of two kinds of mobile communication modes.Have only the clock of two patterns to keep to guarantee that two kinds of patterns can cooperate in harmony synchronously, thereby realize the purpose that dual-mode handset runs well.Otherwise the clock of two kinds of patterns that exist in the same mobile communication equipment can't be synchronous, can cause the confusion of cell phone system.For example, must reach accurate synchronously, could be in the gap of pattern one work, the Useful Information that goes to the base station of receiving mode two to send, thereby guarantee from pattern one to pattern two switch effectively correct.
The problem that why has two kinds of above-mentioned pattern synchronization, be because the time counting mode of different communication patterns is relevant with the radio frames form, and the unlimited frame format of different mode is different, thereby causes the time counting mode of two kinds of patterns to have very big difference.For example, in a WCDMA/GSM dual-mode handset, the frame length of WCDMA pattern is 10 milliseconds, and the frame length of GSM pattern is 60/13 millisecond, and this directly causes the difference of its counting mode, i.e. the asynchronism(-nization) of the two kinds of patterns step.Therefore, in the process of development dual-mode handset, consider the stationary problem of two kinds of patterns generally, promptly to make the two-mode time to convert mutually, simultaneously, also to make as best one can two kinds of patterns do not need synchronously revise existing technical scheme too much.
At present, also not about in the dual-mode handset two kinds of patterns being carried out synchronous patent documentation, but the pertinent literature that this type of is arranged at other field, for example application number is: 200410044884.7, denomination of invention is for having mentioned a kind of method of clock mutually synchronization in the patent application of " a kind of method that realizes the clock mutually synchronization ", its method by sample count is carried out count measurement to a plurality of input reference clock benchmark, and measurement result is weighted average calculating operation, finally obtains the synchronised clock benchmark.The present invention proposes a kind of be used for dual-mode handset two kind patterns different and carry out synchronous method with these method for synchronous, specific as follows described.
Summary of the invention
This paper has proposed the method for two kinds of pattern synchronization in a kind of dual-mode handset, guaranteed to original each pattern software, hardware designs influence minimum.
The method of two kinds of pattern synchronization in a kind of dual-mode handset, operate in the dual-mode handset, it comprises pattern one and 2 two kinds of patterns of pattern, and pattern one comprises first baseband control unit, be used for pattern one is controlled, for example start, stop and managing function that baseband portion provides etc., pattern two comprises second baseband control unit, be used for equally pattern two is controlled, and described mobile phone comprises main control unit, and main control unit is used for all problems of described mobile phone is carried out overall situation control, and carries out communication with described first baseband control unit and second baseband control unit, it is characterized in that described method comprises the steps:
Step 1, main control unit sends synchronization request to first baseband control unit and second baseband control unit;
Step 2, first baseband control unit determines that according to the current time of pattern one time that a pattern two can dispose as processing as described in the following step 3 is predetermined break period, and sets the interrupt signal that occurs in described predetermined break period by the interruption controls unit in the described mobile phone;
Step 5, described second baseband control unit is handled described interruption, the described clock count of preservation mode two;
Step 6, described second baseband control unit is notified described first baseband control unit with the clock count of described pattern two, and described first baseband control unit writes down this time value;
In above-mentioned steps two, pattern two the time as processing as described in the step 3 of can disposing is that the mode by pre-execution or Simulation execution obtains, i.e. Simulation execution pattern two these steps, and obtain the time of carrying out this step.These execution can be finished by the control of main control unit or pattern one, for example the main control unit or first baseband control unit are sent request, and by the second baseband control unit Simulation execution, to handle the three needed times of above-mentioned steps after being finished reinforms main control unit and notifies first baseband control unit by main control unit, perhaps directly notifies first baseband control unit.Perhaps also can directly initiate above-mentioned Simulation execution, directly notify first baseband control unit with correlation time after being finished, perhaps notify main control unit to notify first baseband control unit by main control unit again by second baseband control unit.
In above-mentioned steps three, six, seven, finish notifying operation with message mode.
In above-mentioned steps three, six, seven, be to finish notifying operation in the value mode of revising a constant.
In above-mentioned steps five, described second baseband control unit reads the clock count of the pattern two of being preserved and it is saved in the directly actuated memory of second baseband control unit institute, in order to avoid these loss of datas from the register described in the step 4.
In above-mentioned steps two, the interrupt signal that is provided with in described interruption controls unit is for once carrying out interrupt signal, and promptly this interrupt signal is carried out once the i.e. cancellation automatically in back.
In above-mentioned steps two, the interrupt signal that is provided with in described interruption controls unit is for repeating interrupt signal, not cancellation automatically after promptly this interrupt signal is carried out once, in this case, in step 7, described first baseband control unit notice main control unit synchronous working finish before or simultaneously or should cancel above-mentioned interrupt signal subsequently, take place once more to avoid above-mentioned interrupt signal.
Through after the above-mentioned steps, pattern one can be converted to time of pattern two time of pattern one by following formula:
FrameMode1＝(FrameMode2×FrameLengthMode2/LCM)×(LCM/FrameLengthMode1)+(((FrameMode2％(LCM/FrameLengthMode2))×NMode2+CountMode2)×(TMode2/TMode1))/NMode1
CountMode1＝(((FrameMode2％(LCM/FrameLengthMode2))×NMode2+CountMode2)×(TMode2/TMode1))％NMode1
Wherein, N is the count cycle of every frame, and promptly NMode1 is the frame count cycle of pattern one, and NMode2 is the frame count cycle of pattern two; T is the time of each digit, and TMode1 is the time of the digit of pattern one, and TMode2 is the time of the digit of pattern two; LCM is the least common multiple of two-mode frame length; Frame is the frame number of corresponding modes, and promptly FrameMode1 is the frame number of pattern one, and FrameMode2 is the frame number of pattern two; Count is the count value (TickCount) in corresponding modes one frame, and CountMode2 is the interior count value of a frame of pattern two, is appreciated that CountMode1 is the interior count value of a frame of pattern one; FrameLength is the frame length of corresponding modes, and promptly FrameLengthMode2 is the frame length of pattern two, is appreciated that equally FrameLengthMode1 is the frame length of pattern one.
Similarly, pattern two can be converted to time of pattern two with time of pattern one by above-mentioned formula, correspondingly, FrameMode1 wherein should be replaced with FrameModel2 etc., by that analogy.
By above-mentioned steps and above-mentioned synchronous computing formula, any one pattern can be finished the time synchronized of this pattern and another pattern according to the time of another pattern.With pattern one is example, and concrete mode of operation is: pattern two sends to pattern two with the temporal information of this pattern, and pattern one is received after the temporal information of pattern two time that can time of pattern two be converted to pattern one by above-mentioned synchronous computing formula.Correspondingly, pattern two also can be by the way be converted to time of pattern two with time of pattern one.
Simultaneously, in order to remain the correctness of above-mentioned conversion, also need to carry out timing correction work.These are regularly revised, be meant briefly a particular moment two kinds of patterns each self-recording synchronization point is added a certain amount of skew, this quantitatively can be chosen as the common multiple of the frame length of two kinds of patterns, for example least common multiple.

With reference to figure 1, it has described the sequential schematic diagram of an embodiment of the method for two kinds of pattern synchronization in a kind of dual-mode handset provided by the invention.It will be appreciated by those skilled in the art that, method provided by the invention goes for any pattern that can be applicable to dual-mode handset, two kinds of patterns that for example any frame length is relatively prime, any two kinds of patterns that frame length is relatively prime in WCDMA pattern, GSM pattern, IS95 pattern, WLAN (Wireless Lan) pattern, WiMAX (micro-wave access global inter communication, the Worldwide Interoperability forMicrowave Access) pattern for example.
With reference to figure 1, in a dual-mode handset, comprise main control unit 1, the first baseband control unit 21, second baseband control unit, 22, the first baseband control unit 21 and second baseband control unit 22 under the control of main control unit 1 respectively control model one carry out work with pattern two.Also comprise interrupt control unit 3 and clock register 4 in the described dual-mode handset, it will be appreciated by those skilled in the art that, described dual-mode handset can also comprise other devices, but the method for synchronous that focuses on two kinds of patterns of the present invention, so will not give unnecessary details other devices, those skilled in the art can be understood said apparatus and other devices with reference to prior art and known data.
With reference to figure 1, it finishes synchronizing process one time according to following steps:
At first, main control unit 1 sends synchronization request, step 501 to first baseband control unit 21 and second baseband control unit 22;
Next, first baseband control unit 21 determines that according to the current time of pattern one time that a pattern two can dispose as processing as described in the following step 3 is predetermined break period, and set the interrupt signal that occurs in described predetermined break period, step 502 by the interrupt control unit in the described mobile phone 3;
Next, described first baseband control unit 21 will be notified described second baseband control unit 22 described predetermined break period, and step 503, described second baseband control unit 22 begin to wait for that above-mentioned interruption takes place;
Next, in above-mentioned predetermined break period, described interrupt signal takes place, and described interrupt control unit 3 is saved in the register step 504 with the present clock counting of described pattern two;
Next, described second baseband control unit 22 is handled described interruption, the described clock count of preservation mode two, step 505;
Next, described second baseband control unit 22 is notified described first baseband control unit 21 with the clock count of described pattern two, described first baseband control unit, 21 these time values of record, step 506;
Next, the described timing of described first baseband control unit, 21 cancellations interrupts 508, and notice main control unit synchronous working is finished step 507.
Need to prove, in legend shown in Figure 1,
Representative " message ",
Representative " register access ",
Representative " hardware signal ",
Representative " interrupt signal ".
In the present embodiment, the interrupt signal that sets in step 502 is for repeating interrupt signal, therefore, after this interrupt signal takes place once, the purpose of above-mentioned steps realizes, so initiatively cancel this interrupt signal by described first baseband control unit 21, take place once more to avoid this interrupt signal.Those skilled in the art will appreciate that above-mentioned interrupt signal also can be set to interrupt signal one time, at this moment, after carrying out once, then this interrupt signal is cancelled automatically, and in this case, described first baseband control unit 21 just need be in this interrupt signal of cancellation.The purpose that this interrupt signal is set is in order to obtain the clock count of pattern one and pattern two a specific moment, not influenced flesh and blood of the present invention so how this interrupt signal is provided with.And it will be appreciated by those skilled in the art that, an above-mentioned interrupt signal with repeat interrupt signal and can cause the processing logic of relevant treatment unit slightly different, those skilled in the art can be understood and implemented by prior art and known data, does not give unnecessary details at this.
Those skilled in the art is appreciated that equally that in the present embodiment in above-mentioned steps 504, in fact the clock count of pattern one also is kept in the clock register when taking place to interrupt.As seen in Figure 1, clock register comprises two groups of registers at least, is respectively applied for the clock count of memory module one and the clock count of pattern two.Correspondingly, in the present embodiment, in step 505, described second baseband control unit 22 can read the clock count of two patterns and it is saved in the local memory from above-mentioned clock register 4, thereby can guarantee that two clock counts are all preserved steadily, thereby this is for fear of causing above-mentioned clock count to lose because other processing units or new interruption write new data in this clock register 4.Can be kept in certain memory if can guarantee above-mentioned clock count, and pattern two can read these memories at any time, above-mentioned steps 505 can be omitted so always, and those skilled in the art is appreciated that this.
In fact, because in step 503, described first baseband control unit 21 has been notified described predetermined break period second baseband control unit 22, therefore, at this moment, second baseband control unit 22 can obtain and interrupt the clock count of pattern one constantly, promptly described predetermined break period.Similarly, in step 506, because pattern one do not need the clock count of obtaining mode one from pattern two again, so just do not need again clock count notification mode one with pattern one.
Therefore, by above-mentioned steps, pattern one and pattern two have all been obtained the other side's clock count respectively.After finishing above-mentioned synchronizing process, just can be according to the time of two kinds of patterns of the described formula conversion of summary of the invention.For example, be example with the WCDMA/GSM bimodulus, establishing the every chip of WCDMA (chip) is a digit, the count cycle is 4096 frames; Per 25 symbols of GSM are a digit, and the count cycle is the 26*51 frame, and then above-mentioned reduction formula is:
FrameGsm＝
(FrameWcdma/6)×13
+(((FrameWcdma％6)×38400+CountWcdma)×((1/3.84M)/(12/13M)))/5000
CountGsm＝
(((FrameWcdma％6)×38400+CountWcdma)×((1/3.84M)/(12/13M)))％5000
Equally:
FrameWcdma＝
(FrameGsm/13)×6
+(((FrameGsm％13)×5000+CountGsm)×((12/13M)/(1/3.84M)))/38400
CountWcdma＝
(((FrameGsm％13)×5000+CountGsm)×((12/13M)/(1/3.84M)))％38400
In the present embodiment, the frame length of above-mentioned WCDMA pattern is 10 milliseconds, and the frame length of GSM pattern is 60/13 millisecond, and the frame length ratio of two kinds of patterns is 13/6.Therefore, per 60 milliseconds of arrival are the least common multiple of two kinds of pattern frame lengths once, i.e. 6 WCDMA model frames, 13 GSM model frames.
In the present embodiment, the count value of a GSM model frame (TickCount) is that the count value (TickCount) of 5000, one WCDMA model frames is 38400.A count value (TickCount) of GSM pattern is 12/13 millisecond in the time of second.The time in second of a count value (TickCount) expression of WCDMA pattern is 1/3.84 millisecond.
Those skilled in the art will appreciate that according to above-mentioned formula and concrete data, can finish computing the time synchronized of two kinds of patterns.
Particularly, can further understand sequential shown in Figure 1 by following embodiment, with reference to figure 2.In the present embodiment, we are that example is described synchronous detailed process with the WCDMA/GSM dual-mode handset still.
In the present embodiment, above-mentioned main control unit 1 sends the moment 81 of above-mentioned " synchronization request ", is the time of WCDMA pattern: Frame:10+Count:1.
The WCDMA pattern obtains pattern two within 10 milliseconds of fixed delays, and promptly the GSM pattern can be finished the Interrupt Process in the above-mentioned synchronizing process, determines that therefore fixed delay is 10 milliseconds.I.e. predetermined break period 82, be the time Frame:11+Count:10 of WCDMA pattern.Those skilled in the art will appreciate that in actual applications the said fixing time delay may be far smaller than above-mentioned 10 milliseconds, but cited time delay only is for method of the present invention being described, not influencing flesh and blood of the present invention in the present embodiment.
Then, the WCDMA pattern is with the baseband control unit of above-mentioned break period with a message informing GSM pattern.
Interrupt control unit arrives above-mentioned break period 82, produced interruption when being the Frame:11+Count:10 of WCDMA mode time, the clock count of clock register 4 these two patterns constantly of record, at this moment, the time that register 4 has been preserved the WCDMA pattern is Frame:11+Count:10, and the time of preserving the GSM pattern is Frame:7+Count:17.
Notify the WCDMA pattern with Frame:7+Count:17 break period of said GSM pattern with message mode.
The message that main control unit 1 sends according to the WCDMA pattern learns synchronously and finishes that WCDMA pattern cancellation is simultaneously regularly interrupted, and synchronous working is finally finished.
In the present embodiment, above-mentioned notice work is that mode by message realizes.And it will be appreciated by those skilled in the art that, in other similar embodiment, above-mentioned notice work also can be by revising a constant, for example the mode of a global variable is achieved, one or several global variables promptly are set represent correlated identities respectively, whether interruption for example is set, interrupt the scheduled time, whether the clock numeration is finished etc. synchronously.
Through after the above-mentioned steps, can calculate the time of corresponding this pattern of time of another kind of pattern by aforementioned calculation formula W CDMA pattern or GSM pattern.
For example, suppose the time of WCDMA pattern notice GSM pattern: the Frame:21+Count:10 moment 83 in the WCDMA pattern, the GSM pattern should be made certain processing, for example carve the GSM pattern at this moment and can handle the mobile communication signal, then the GSM pattern can be converted to the time of this WCDMA pattern the time of GSM pattern, that is:
(Frame?21+4096-Frame?11)％4096＝10
(Count?10+38400-Count?10)％38400＝0
Thereby obtain time difference with the WCDMA pattern of lock in time.
Equally, the time difference that is scaled the GSM pattern is:
FrameGsm＝(10/6)×13+(((10％6)×38400+0)×((1/3.84M)/(12/13M)))/5000＝21
CountGsm＝(((10％6)×38400+0)×((1/3.84M)/(12/13M)))％5000＝3333
The moment that is scaled the GSM pattern is:
Frame?21+Frame?7＝28
Count?3333+Count?17＝3350
So according to the notice of WCDMA pattern, the GSM pattern can be at the time of GSM pattern: Frmae 28, Count 3350 constantly begins to handle accordingly, for example carries out the measurement of signal strength signal intensity.
With reference to figure 3, it has described the schematic diagram of applied dual-mode handset of one embodiment of the present of invention and base station communication.In the present embodiment, described dual-mode handset 7 has two kinds of patterns: GSM pattern and IS95 pattern.Correspondingly, this dual-mode handset 7 is in the coverage of a GSM base station 61 and IS95 base station 62, and dual-mode handset 7 voice service of always using the GSM pattern to provide.At a time, GSM pattern notice IS95 pattern, Frmae 28 in the GSM pattern, Count3350 constantly, the IS95 pattern can be carried out the measurement of signal strength signal intensity, then the IS95 pattern is according to the method for the described embodiment of Fig. 1 Frmae 28 with the said GSM pattern, and Count 3350 is converted to the moment of IS95 pattern constantly, and carries out the measurement of the signal strength signal intensity of IS95 pattern constantly at this.
Below, specifically describe an embodiment who regularly revises.Still be example with the WCDMA/GSM bimodulus in the foregoing description.Because the least common multiple of the frame length of WCDMA/GSM bimodulus is 60 milliseconds, so 60 milliseconds of every mistakes, two-mode adds each self-recording synchronization point and is equivalent to 60 milliseconds skew.Be that the GSM pattern is offset 13 frames forward, the WCDMA pattern is offset 6 frames forward.Those skilled in the art will appreciate that above-mentioned side-play amount is that the common multiple of the frame length of two patterns gets final product, this does not influence flesh and blood of the present invention.
Those skilled in the art will appreciate that in order to realize said method the logic that at first needs to revise above-mentioned interruption controls unit makes it meet the requirement that step in the clock register is interrupted and the clock count of pattern one, pattern two is stored in above-mentioned generation.Particularly,, then can write one section code of finishing above-mentioned steps if adopt DSP (digital signal processor) to realize, and and then realize its logical changes; If adopt FPGA to realize, then can write one section VHDL code and be used for finishing above-mentioned steps, and and then realize its logical changes.Above-mentioned concrete operation, those skilled in the art can be understood and implemented with reference to prior art and known data, for example at least can be with reference to " TMS320F206 DSP structure, principle and application " (Li Gang, woods icepro, Ye Wenyu work, publishing house of BJ University of Aeronautics ﹠ Astronautics, 2002), " the senior application and development guide of CPLD/FPGA " (Ren Xiaodong, Wen Bozhu, the Electronic Industry Press, 2003) or similar books.
Secondly, need increase the code of realizing aforesaid operations to main control unit 1, first baseband control unit 21 and second baseband control unit 22.Particularly, the programming language that can discern with reference to corresponding process chip or other processing units and the code that increases aforesaid operations, for example the codes etc. of 22 above-mentioned predetermined break periods of second baseband control unit is notified in increase in first baseband control unit 21.Those skilled in the art can be understood this partial content and implemented with reference to prior art and known data.
Although the present invention is illustrated with aforesaid preferred embodiment, but the foregoing description is not to be used for limiting the present invention, any technical staff that this field is familiar with, enlightenment according to design philosophy of the present invention, concrete summary of the invention and embodiment, should various changes and adjustment, and by these changes with adjust resulting new content and should be contained by content of the present invention.
