In embodiments of the present invention, based on above-mentioned various pre-set work after, we just can arrange according to these and determine the operating frequency of the MIPI of work at present in terminal, in order to avoid terminal communication is interfered by the operating frequency of terminal communication period MIPI, wish that the operating frequency of the MIPI of work at present falls outside the frequency range of communication frequency, or, when the operating frequency of MIPI of work at present cannot be avoided to fall in the frequency range of communication frequency, wish select work at present MIPI operating frequency try one's best away from the mid frequency of communication frequency place frequency range some.

In embodiments of the present invention, based on above-mentioned design philosophy, when terminal communication, it would be desirable to first obtain frequency and the bandwidth of communication frequency, obtain the frequency range of this communication frequency according to the frequency obtained and bandwidth, be not particularly limited for obtaining the method for the frequency range of this communication frequency here.After obtaining the frequency range of communication frequency; need to obtain further the operating frequency of the MIPI of work at present; need exist for explanation be; when terminal just starts to communicate; the MIPI of work at present, it will usually using the first predeterminated frequency in the group of frequencies corresponding to the interface type corresponding to this MIPI as the initial operating frequency of this MIPI.We need to determine whether that can this initialization always as the operating frequency of this MIPI.Need exist for explanation be, during frequency in pre-setting group of frequencies, in advance the multiple predeterminated frequencies arranged can be added label, and the predeterminated frequency that with the addition of label is ranked up, here this label can carry out self-defined, such as, according to the size of frequency values, label is set to 1, 2, 3 ..., or, it is set to a, b, c ... etc., here this group news mode can also carry out self-defined, such as, arrange from low to high according to the size of frequency values, or arrange from high to low, furthermore it is arranged in order etc. according to the order that arranges of predeterminated frequency, at this, definition and sortord for label are all not particularly limited.For pre-setting label and the group of frequencies put in order, we just can be using the predeterminated frequency that makes number one in group of frequencies as the first predeterminated frequency, or using the predeterminated frequency that rolls into last place in group of frequencies as the first predeterminated frequency.In other embodiments, we can not also carry out label setting and sequence to the predeterminated frequency in group of frequencies, any one predeterminated frequency inside selection is as the first predeterminated frequency, and using this predeterminated frequency as terminal communication time, the initial operating frequency of the acquiescence of the MIPI of a certain interface type of work at present.

In embodiments of the present invention, it can further be stated that, when terminal communication, the MIPI having different interface types works simultaneously, we need respectively the different MIPI in the MIPI of the different interface type of work at present to be obtained the first corresponding predeterminated frequency, i.e. its initial operating frequency respectively.Here, the corresponding first different predeterminated frequency of MIPI meeting of different interface types, the corresponding first identical predeterminated frequency of MIPI meeting of identical interface type, acquisition is belonged to the different MIPI of identical interface type, owing to the initial operating frequency of its correspondence is the most identical, therefore, we can obtain the initial operating frequency corresponding to a kind of style interface, after i.e. first predeterminated frequency, and verify when this first predeterminated frequency is in the frequency range of communication frequency, unification carries out resetting operating frequency for the MIPI that this first predeterminated frequency is corresponding.

S102, by the first predeterminated frequency compared with the frequency range of communication frequency, it is judged that whether the first predeterminated frequency falls in the frequency range of communication frequency.

In embodiments of the present invention, obtain terminal set up communication time each MIPI the first predeterminated frequency after, by the way of by the first predeterminated frequency compared with the frequency range of communication frequency, it is judged that whether the first predeterminated frequency falls in the frequency range of communication frequency.

S103, when the first predeterminated frequency does not falls within the frequency range of communication frequency, using the first predeterminated frequency as the present operating frequency of MIPI.

In embodiments of the present invention, by the comparison in step S102, we can judge the operating frequency of the MIPI of current default according to comparative result, and whether the i.e. first predeterminated frequency meets the requirements, it is possible to always as the operating frequency of MIPI of work at present.Here, comparative result only has two kinds, a kind of be the frequency range that the first predeterminated frequency does not falls within communication frequency in, another kind of result is that the first predeterminated frequency falls in the frequency range of communication frequency.For two kinds of different comparative results, the present invention program can take different measures.

When the first predeterminated frequency does not falls within the frequency range of communication frequency, illustrate that this first predeterminated frequency meets the requirements, current signal of communication will not be interfered, therefore may proceed to the present operating frequency using this first predeterminated frequency as the MIPI of work at present.

When the first predeterminated frequency falls in the frequency range of communication frequency, illustrate that this first predeterminated frequency is undesirable, current signal of communication can be interfered, thus without continuing this first predeterminated frequency of the employing present operating frequency as the MIPI of work at present, need from default group of frequencies, reselect a satisfactory predeterminated frequency.Specific implementation method is as described below.

Alternatively, the method also includes:

S201, when the first predeterminated frequency falls in the frequency range of communication frequency, obtain the first frequency group corresponding with first interface type.

S202, whether fall in the frequency range of communication frequency according to predeterminated frequency in addition to the first predeterminated frequency in preset order checking first frequency group；And determine that can the predeterminated frequency of current authentication as the present operating frequency of MIPI according to the result.

Below by citing, such scheme is illustrated:

S301, when the first predeterminated frequency falls in the frequency range of communication frequency, obtain the first frequency group corresponding with first interface type.

S302, from described first frequency group, obtain the second predeterminated frequency, and by described second predeterminated frequency compared with described communication frequency, it is judged that whether described second predeterminated frequency falls in the frequency range of described communication frequency.

S303, when described second predeterminated frequency does not falls within the frequency range of described communication frequency, using described second predeterminated frequency as the present operating frequency of described MIPI.

S304, when described second predeterminated frequency falls in the frequency range of described communication frequency, return step S302, from described first frequency group, obtain the second predeterminated frequency, it is judged that whether described 3rd predeterminated frequency falls in the frequency range of described communication frequency.

Repeat above-mentioned step S302 to step S304, until the predeterminated frequency obtained from first frequency group in the frequency range not falling within communication frequency, directly using this predeterminated frequency as the operating frequency of the MIPI of the work at present corresponding with first frequency group；Or until the whole predeterminated frequencies verified in first frequency group, if still there is no the predeterminated frequency outside the frequency range of communication frequency after the whole predeterminated frequencies verified in first frequency group, or, when all predeterminated frequency all falls in the frequency range of communication frequency, process according to following proposal.

Need exist for explanation, foregoing is illustrated as a example by verifying the predeterminated frequency in first frequency group, same as mentioned above for the verification method of predeterminated frequency in other group of frequencies, do not repeat them here.

In embodiments of the present invention, will be apparent from solution when the whole predeterminated frequencies in a group of frequencies all fall in the frequency range of communication frequency below.

Alternatively, the method also includes:

S401, when the whole predeterminated frequencies in first frequency group all fall in the frequency range of communication frequency, obtain communication frequency frequency range in center frequency value.

S402, by the whole predeterminated frequencies in first frequency group respectively compared with center frequency value.

S403, using in whole predeterminated frequencies with the predeterminated frequency of the maximum absolute value of the difference of center frequency value as the present operating frequency of MIPI.

In embodiments of the present invention, the design philosophy of such scheme is: if whole predeterminated frequencies all falls in the frequency range of current communication frequency in a group of frequencies, look for the nearest predeterminated frequency of marginal frequency apart from the frequency range of this communication frequency as the operating frequency of the MIPI of current authentication from these predeterminated frequencies, in other words, look for the farthest predeterminated frequency of mid frequency apart from the frequency range of this communication frequency as the operating frequency of the MIPI of current authentication.

Alternatively, the method also includes:

In embodiments of the present invention, perhaps the predeterminated frequency of the maximum absolute value of multiple difference with center frequency value is detected by step S401 to S403, in this case, we can differences with center frequency value multiple from this maximum absolute value predeterminated frequency arbitrarily select an operating frequency as MIPI, or select the minimum operating frequency as MIPI of the predeterminated frequency medium frequency value of the maximum absolute value of multiple difference with center frequency value.Certainly, in other embodiments, it is also possible to carry out other according to application scenarios and arrange.

In embodiments of the present invention, when predeterminated frequencies whole in a group of frequencies all falls in the frequency range of current communication frequency, the present invention have also been devised another kind of solution, is described in detail the program below.

Alternatively, the method also includes:

S501, when the first predeterminated frequency falls in the frequency range of communication frequency, the first predeterminated frequency is adjusted with the first default adjustment amplitude.

S502, will adjust after the first predeterminated frequency compared with communication frequency, it is judged that whether the first predeterminated frequency after adjustment falls in the frequency range of communication frequency；

S503, when the first predeterminated frequency after adjusting does not falls within the frequency range of communication frequency, the first predeterminated frequency after adjusting is as the present operating frequency of MIPI.

S504, when the first predeterminated frequency after adjusting falls in the frequency range of communication frequency, obtain the second predeterminated frequency in first frequency group, and judge whether the second predeterminated frequency falls in the frequency range of communication frequency.

S505, when the second predeterminated frequency falls in the frequency range of communication frequency, the second predeterminated frequency is adjusted with the second default adjustment amplitude；And judge whether the second predeterminated frequency after adjusting falls in the frequency range of communication frequency.

In embodiments of the present invention, foregoing had been introduced, a difference can be had between each two predeterminated frequency in each group of frequencies, we can pre-set an adjustment amplitude for each predeterminated frequency, this adjustment amplitude is necessarily smaller than the difference between two predeterminated frequencies, when we judge that the predeterminated frequency of current authentication falls in the frequency range of communication frequency, before verifying next not verified predeterminated frequency according to preset order, first predeterminated frequency for this current authentication can do a fine setting, this fine setting is i.e. the fine setting done according to the adjustment amplitude preset.Not falling within the frequency range of communication frequency if carried out the predeterminated frequency after adjusting, we just can be using the predeterminated frequency after adjustment as the present operating frequency of MIPI.If the predeterminated frequency after being adjusted still falls within the frequency range of communication frequency, next predeterminated frequency is verified by again.This scheme is highly effective for the predeterminated frequency just fallen in the band edge region of communication frequency, it is to avoid follow-up multiple authentication, improves work efficiency.

Illustrate below by citing.nullSuch as，If the difference between the first predeterminated frequency in first frequency group and the second predeterminated frequency is 1MHZ，First predeterminated frequency is 825MHZ，Second predeterminated frequency is 826KHZ，The frequency range of communication frequency is 825MHZ～835MHZ，The adjustment amplitude assuming the first predeterminated frequency preset is ± 0.5MHZ，Then when judging that the first predeterminated frequency 825MHZ just falls in 825MHZ～835MHZ by checking，First predeterminated frequency 825MHZ is adjusted 0.5MHZ to the left，I.e.，825MHZ-0.5MHZ，Obtaining the first predeterminated frequency after adjusting is 824.5MHZ，At this moment the first predeterminated frequency after being adjusted would not fall in communications band 825MHZ～835MHZ，Then using the first predeterminated frequency 824.5MHZ after this adjustment as the operating frequency of current MIPI，Avoid the detection continued follow-up predeterminated frequency.
