Description

Communication method, mobile terminal and medium

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a communication method and a mobile terminal.

Background

The 5G communication technology is a new generation mobile communication technology following 4G because it has the characteristics of high rate, low latency and large capacity. Sub-6GHz will become an intermediate technology for the existing 4G mobile communication technology to iterate to the 5G mobile communication technology. And the frequency band used by Sub-6GHz is higher in frequency, the attenuation of signals in the space channel is larger, and the frequency band used by 4G communication is lower than that of Sub-6GHz, and the loss in the space channel is small. Therefore, in practical application, a scene that 4G, Sub-6GHz and WIFI coexist exists, the 4G is responsible for accessing the terminal into the core network, the Sub-6GHz is responsible for large throughput data interaction between the terminal and the core network, and the WIFI is responsible for connecting the terminal as a hotspot with other intelligent equipment.

In the prior art, due to the fact that circuit devices in the communication terminal have nonlinearity, when 4G, Sub-6GHz and WIFI coexist, intermodulation products can be generated between signals of 4G, Sub-6GHz and WIFI, and the intermodulation products can fall into the receiving frequency bands of 4G, Sub-6GHz and 2.4G WIFI, so that interference is generated on receiving of the system. For example, in the communication system, the second order intermodulation products of the Sub-6GHz communication band N77 (transmission band 3.3-4.2GHz), the 4G communication band LTE B8 (transmission band 880 MHz-915 MHz) and the 2.4G WIFI fall within the N77, LTE B8 (reception band 925 and 960MHz) and 2.4G WIFI reception bands (2412MHz-2472MHz), thereby interfering with the reception performance of N77, LTE B8 and 2.4G WIFI, and reducing the performance of the whole communication system.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1, a flowchart illustrating steps of a communication method according to a first embodiment of the present invention is shown. The communication is applied to a mobile terminal, wherein the mobile terminal has a first communication mode and a second communication mode.

The communication method of the embodiment of the invention can comprise the following steps:

step 101: and acquiring a first communication carrier parameter corresponding to the first communication mode and a second communication carrier parameter corresponding to the second communication mode.

The communication modes may include Sub-6GHz, 4G, WIFI and other communication modes. The first communication carrier parameter may be a frequency or a transmission/reception timing of the first communication carrier, and the second communication carrier parameter may be a frequency or a transmission/reception timing of the second communication carrier. In practical applications, the frequency of the communication carrier is each frequency point within the operating frequency band, and the transmission/reception timing of the communication carrier is each timing of the transmission/reception time slot of the communication carrier.

Step 102: when the first communication carrier parameter and the second communication carrier parameter do not meet the first preset condition, the first communication carrier parameter is adjusted to be a third communication carrier parameter, and the second communication carrier parameter is adjusted to be a fourth communication carrier parameter, wherein the communication interference generated between the third communication carrier and the fourth communication carrier is smaller than the communication interference generated between the first communication carrier and the second communication carrier.

The first preset condition may be, for example, that the amount of communication interference generated between the first communication carrier and the second communication carrier is less than a preset threshold.

Specifically, when the communication interference amount generated between the first communication carrier and the second communication carrier is greater than or equal to the preset threshold, the first communication carrier parameter is adjusted to be the third communication carrier parameter, that is, the communication carrier in the first communication mode is adjusted from the first communication carrier to the third communication carrier, and the second communication carrier parameter is adjusted to be the fourth communication carrier parameter, that is, the communication carrier in the second communication mode is adjusted from the second communication carrier to the fourth communication carrier, so that the third communication carrier parameter and the fourth communication carrier parameter satisfy the first preset condition, or the communication interference amount generated between the third communication carrier and the fourth communication carrier is smaller than the communication interference amount generated between the first communication carrier and the second communication carrier, so that the communication interference amount generated between the communication carriers in the communication modes can be reduced.

The communication interference amount may be energy in which an intermodulation product generated between the communication carriers of the first communication mode and the second communication mode falls within a reception range (e.g., a reception band or a reception slot) of a communication carrier of another communication mode, energy in which an intermodulation product generated between the first communication mode and another communication mode falls within a reception range (e.g., a reception band or a reception slot) of the second communication mode, or the like.

The preset threshold value can be predetermined in a theoretical calculation or laboratory test mode according to the actual conditions such as the type of the communication carrier parameter, the communication mode, the application requirement and the like, and the specific preset threshold value and the like are not limited in the application.

In the communication method provided by this embodiment, when the first communication carrier parameter and the second communication carrier parameter do not satisfy the first preset condition, the first communication carrier parameter is adjusted to be the third communication carrier parameter, and the second communication carrier parameter is adjusted to be the fourth communication carrier parameter.

Example two

Referring to fig. 2, a flowchart of steps of a communication method according to a second embodiment of the present invention is shown. In this embodiment, the first communication carrier parameter is a first carrier frequency of the first communication mode, the second communication carrier parameter is a second carrier frequency of the second communication mode, and the mobile terminal further has a third communication mode, where the carrier frequency of the third communication mode is a designated frequency.

The communication method of the embodiment of the invention specifically comprises the following steps:

step 201: and acquiring a first communication carrier parameter corresponding to the first communication mode and a second communication carrier parameter corresponding to the second communication mode.

The following description will take the first communication mode as Sub-6GHz, the second communication mode as 4G, and the third communication mode as WIFI. The first communication carrier parameter is the frequency Fa of the first communication carrier in the first communication mode, the second communication carrier parameter is the frequency Fb of the second communication carrier in the second communication mode, and the communication carrier frequency in the third communication mode is the designated frequency Fc.

Step 202: judging whether a first difference absolute value between the first carrier frequency and the second carrier frequency and a second difference absolute value between the first carrier frequency and the second carrier frequency and the designated frequency are larger than a first threshold value or not, and if so, meeting a first preset condition; if not, the first preset condition is not met.

Specifically, a first difference absolute value of the first carrier frequency Fa of the first communication mode and the second carrier frequency Fb of the second communication mode may be first calculated: Δ F1 ═ Fa-Fb |.

Then, a second difference absolute value of the first difference absolute value Δ F1 and the specified frequency Fc is calculated: Δ F2 ═ Δ F1-Fc |.

Then, whether the second difference absolute value Δ F2 is greater than the first threshold X is determined, if the second difference absolute value Δ F2 is greater than the first threshold X, the first preset condition is met, and step 203 is executed; if the second absolute difference value Δ F2 is less than or equal to the first threshold value X, the first preset condition is not satisfied, and step 204 is executed. The first threshold value X may be preset through laboratory tests and the like according to the actual working conditions of the communication mode, performance requirements and the like, and the specific numerical value is not limited in the present application.

It should be noted that the essence of this step is to determine whether the first difference absolute value Δ F1, i.e., the frequency Δ F1 of the second order intermodulation product of the first carrier frequency Fa and the second carrier frequency Fb, falls within the range of the first threshold X from the designated frequency Fc. Therefore, the specific implementation of determining whether the first carrier frequency and the second carrier frequency (the first communication carrier parameter and the second communication carrier parameter) satisfy the first preset condition is not limited to the manner described in this embodiment.

Step 203: when the first communication carrier parameter and the second communication carrier parameter meet a first preset condition, determining that the working carrier parameter of the first communication mode is the first communication carrier parameter, and the working carrier parameter of the second communication mode is the second communication carrier parameter.

When the second absolute difference value Δ F2 is greater than the first threshold X, it indicates that the frequency Δ F1 of the second-order intermodulation product between the first carrier frequency Fa and the second carrier frequency Fb does not fall within the range from the designated frequency Fc to the first threshold X, at this time, the frequency interval between the carrier frequencies Fa, Fb and Fc is relatively large, the energy of the intermodulation product generated between the communication carrier of the first communication mode and the communication carrier of the second communication mode falling within the receiving frequency band range of the third communication mode is negligible, and the influence of the intermodulation product on the performance of the entire communication system is small. Thus, the carrier frequency of the first communication mode may be determined to be the first carrier frequency and the carrier frequency of the second communication mode may be determined to be the second carrier frequency.

Step 204: when the first communication carrier parameter and the second communication carrier parameter do not meet the first preset condition, traversing the preset parameters of the first communication mode and the second communication mode, adjusting the first communication carrier parameter to be a third communication carrier parameter, and adjusting the second communication carrier parameter to be a fourth communication carrier parameter.

The preset parameters in this embodiment are frequency points in the transmitting frequency band or the receiving frequency band of each communication mode of the mobile terminal.

If the second absolute difference value Δ F2 is less than or equal to the first threshold X, it indicates that the frequency Δ F1 of the second-order intermodulation product between the first carrier frequency Fa and the second carrier frequency Fb falls within the range from the designated frequency Fc to the first threshold X, and the energy (amount of communication interference) of the intermodulation product generated between the communication carrier of the first communication mode and the communication carrier of the second communication mode falling within the receiving band range of the third communication mode is greater than or equal to the preset threshold, at this time, the preset parameters of the first communication mode and the second communication mode may be traversed, the first carrier frequency Fa (first communication carrier parameter) is adjusted to the third carrier frequency Fa '(third communication carrier parameter), and the second carrier frequency Fb (second communication carrier parameter) is adjusted to the fourth carrier frequency Fb' (fourth communication carrier parameter). The first carrier frequency Fa and the third carrier frequency Fa 'are both preset parameters of the first communication mode, namely frequency points in a transmitting frequency band or a receiving frequency band, and the first carrier frequency Fa and the third carrier frequency Fa' can be the same or different; the second carrier frequency Fb and the fourth carrier frequency Fb' are both preset parameters of the second communication mode, i.e., frequency points in the transmitting frequency band or the receiving frequency band, which may be the same or different.

Step 205: and judging whether the third communication carrier parameter and the fourth communication carrier parameter meet a first preset condition.

The execution manner of this step is similar to that of step 202, and may specifically include: determining whether a first absolute difference value Δ F1 ═ Fa ' -Fb ' between the third carrier frequency Fa ' and the fourth carrier frequency Fb ' and a second absolute difference value Δ F2 ═ Δ F1-Fc ' between the third carrier frequency Fa ' and the fourth carrier frequency Fb ' are greater than a first threshold X; if the second absolute difference value Δ F2 is greater than the first threshold X and meets the first preset condition, step 206 is executed, and if the preset parameters of the first communication mode and the second communication mode are traversed, the second absolute difference value Δ F2 is still less than or equal to the first threshold X and does not meet the first preset condition, step 207 is executed.

Step 206: and when the third communication carrier parameter and the fourth communication carrier parameter meet a first preset condition, determining that the working carrier parameter of the first communication mode is the third communication carrier parameter, and the working carrier parameter of the second communication mode is the fourth communication carrier parameter.

If Δ F2 is greater than the first threshold X, the adjusted third carrier frequency Fa 'and fourth carrier frequency Fb' satisfy a first preset condition, which indicates that the frequency Δ F1 of the second-order intermodulation product of the third carrier frequency Fa 'and fourth carrier frequency Fb' does not fall within the range from the designated frequency Fc to the first threshold X, at this time, the frequency intervals between the carrier frequencies Fa ', Fb' and Fc are relatively large, at this time, the energy of the intermodulation product between every two three carriers can be ignored, and the influence of the intermodulation product on the performance of the entire communication system is small. Therefore, it can be determined that the carrier frequency of the first communication mode is the third carrier frequency Fa 'and the carrier frequency of the second communication mode is the fourth carrier frequency Fb'.

In practical applications, the present embodiment provides a way to traverse the preset parameters of the first communication mode and the second communication mode as follows: the first carrier frequency Fa may be first sequentially adjusted to frequency points Fa1 ', Fa 2', … … Fan 'in the preset parameters of the first communication mode to obtain a third carrier frequency Fa', the second carrier frequency Fb is then sequentially adjusted to frequency points Fb1 ', Fb 2', … … Fbm 'in the preset parameters of the second communication mode to obtain a fourth carrier frequency Fb', and the third carrier frequency Fa 'and the fourth carrier frequency Fb' which satisfy the first preset condition are respectively used as working carrier parameters of the first communication mode and the second communication mode, or when the m × n combinations of the third carrier frequency Fa 'and the fourth carrier frequency Fb' do not satisfy the first preset condition, step 207 is executed.

Step 207: and when the preset parameters of the first communication mode and the second communication mode are traversed and the first preset condition is not met, determining the working carrier parameters of the first communication mode and the second communication mode as communication carrier parameter values enabling the absolute value of the second difference to be the maximum.

When all frequency points in the frequency bands transmitted or received by the first communication mode and the second communication mode are traversed and the first preset condition is still not met, namely, both the delta F2 are smaller than or equal to the first threshold value X, at this time, the carrier frequency of the first communication mode and the carrier frequency of the second communication mode are determined to be the frequency point which enables the absolute value of the second difference delta F2 to be the maximum respectively. In this way, it is ensured that the frequency of the second order intermodulation product between the first communication mode and the second communication mode is farthest from the carrier frequency of the third communication mode, i.e. the designated frequency Fc, thereby minimizing the influence of the intermodulation product on the third communication mode and the influence of the intermodulation product on the performance of the entire communication system.

In the communication method provided by the embodiment of the present invention, when a first carrier frequency in a first communication mode and a second carrier frequency in a second communication mode satisfy a first preset condition, the first carrier frequency and the second carrier frequency that satisfy the first preset condition are determined as carrier frequencies in the first communication mode and the second communication mode; when the first carrier frequency and the second carrier frequency do not meet the first preset condition, the first carrier frequency (the first communication carrier parameter) is adjusted to be the third carrier frequency (the third communication carrier parameter), the second carrier frequency (the second communication carrier parameter) is adjusted to be the fourth carrier frequency (the fourth communication carrier parameter), and determines a third carrier frequency and a fourth carrier frequency that satisfy a first preset condition or maximize an absolute value of the second difference as carrier frequencies of the first communication mode and the second communication mode, this may be so that the intermodulation product frequencies generated between the first and second communication modes do not fall around the carrier frequency of the third communication mode, or the frequency of the intermodulation product is far away from the carrier frequency of the third communication mode as far as possible, so that the interference of the intermodulation product on the work of the third communication mode is reduced, and the influence of the intermodulation product on the performance of the whole communication system is further reduced.

EXAMPLE III

Referring to fig. 3a, a flowchart of steps of a communication method according to a third embodiment of the present invention is shown. In this embodiment, the first communication carrier parameter is a first transmission timing of the communication carrier in the first communication mode, and the second communication carrier parameter is a first reception timing of the communication carrier in the second communication mode.

step 301: and acquiring a first communication carrier parameter corresponding to the first communication mode and a second communication carrier parameter corresponding to the second communication mode.

In this embodiment, the first communication mode is Sub-6GHz, and the second communication mode is WIFI, for example, the mobile terminal in this embodiment may further have other communication modes such as 4G. The first communication carrier parameter is a first transmission timing Ta of the first communication mode, and the second communication carrier parameter is a first reception timing Tb of the second communication mode.

Step 302: judging whether a third difference absolute value of the first transmitting time sequence and the first receiving time sequence is greater than a second threshold, if so, meeting a first preset condition; if not, the first preset condition is not met.

Specifically, the third difference absolute value Δ T-Ta-Tb-of the first transmission timing Ta and the first reception timing Tb may be first calculated.

Then, it is determined whether the third difference absolute value Δ T is greater than the second threshold Y, if the third difference absolute value Δ T is greater than the second threshold Y and meets the first preset condition, step 303 is executed, and if the third difference absolute value Δ T is less than or equal to the second threshold Y and does not meet the first preset condition, step 304 is executed.

The second threshold value Y may be preset through laboratory tests and the like according to the actual working conditions of the communication mode, performance requirements and the like, and the specific numerical value is not limited in the present application.

It should be noted that the essence of this step is to determine whether the transmission time slot of the first communication mode coincides with the reception time slot of the second communication mode. Therefore, the specific implementation of determining whether the first transmission timing and the second reception timing (the first communication carrier parameter and the second communication carrier parameter) satisfy the first preset condition is not limited to the manner described in this embodiment.

Step 303: when the first communication carrier parameter and the second communication carrier parameter meet a first preset condition, determining that the working carrier parameter of the first communication mode is the first communication carrier parameter, and the working carrier parameter of the second communication mode is the second communication carrier parameter.

Due to the existence of nonlinearity of the device in the second communication mode WIFI, the transmitting signal of the first communication mode Sub-6GHz and the transmitting signal of another communication mode, such as 4G, may perform intermodulation, and if the third absolute difference value Δ T is greater than the second threshold Y, it indicates that the transmitting time slot of the first communication mode and the receiving time slot of the second communication mode are not overlapped, as shown in fig. 3 b. At this time, even if the second-order intermodulation product is generated between the transmission signal of the first communication mode and the transmission signal of another communication mode, such as 4G, the second-order intermodulation product does not fall into the receiving time slot of the second communication mode WIFI, that is, the energy of the intermodulation product generated between the communication carrier of the first communication mode and the communication carrier of another communication mode falling into the receiving time slot range of the second communication mode WIFI can be ignored, so that the operation of the second communication mode WIFI is not interfered. Therefore, it can be determined that the transmission timing of the communication carrier of the first communication mode is the first transmission timing and the reception timing of the second communication mode is the first reception timing.

Step 304: when the first communication carrier parameter and the second communication carrier parameter do not meet the first preset condition, traversing the preset parameters of the first communication mode and the second communication mode, adjusting the first communication carrier parameter to be a third communication carrier parameter, and adjusting the second communication carrier parameter to be a fourth communication carrier parameter.

The preset parameters are all time sequences of the receiving and sending time slots of the communication carriers of all communication modes of the mobile terminal.

If the third absolute difference value Δ T is less than or equal to the second threshold value Y, it indicates that the transmission time slot of the first communication mode overlaps with the reception time slot of the second communication mode, as shown in fig. 3 c. At this time, the second-order intermodulation product generated between the transmission signal of the first communication mode Sub-6GHz and the transmission signal of another communication mode, such as 4G, just falls into the receiving time slot of the second communication mode WIFI, that is, the energy (communication interference amount) of the intermodulation product generated between the communication carrier wave of the first communication mode and the communication carrier wave of another communication mode falling into the receiving time slot range of the second communication mode is greater than or equal to the preset threshold, which may interfere with the operation of the second communication mode WIFI. At this time, the first transmission timing Ta (first communication carrier parameter) may be adjusted to the second transmission timing Ta '(third communication carrier parameter) and the first reception timing Tb (second communication carrier parameter) may be adjusted to the second reception timing Tb' (fourth communication carrier parameter) through all transmission timings of the first communication mode and all reception timings of the second communication mode. The first transmission time sequence Ta and the second transmission time sequence Ta' are both preset parameters of the first communication mode, namely, the time sequences of the transmission time slots of the communication carrier of the first communication mode can be the same or different; the first receiving timing Tb and the second receiving timing Tb' are both preset parameters of the second communication mode, that is, the timing of the receiving time slot of the communication carrier in the second communication mode may be the same or different. Each time sequence of the first communication mode communication carrier transmission time slot and each time sequence of the second communication mode communication carrier receiving time slot can be predetermined according to actual conditions.

Step 305: and judging whether the third communication carrier parameter and the fourth communication carrier parameter meet a first preset condition.

The execution manner of this step is similar to that of step 302, and may specifically include: and determining whether a third difference absolute value Δ T ═ Ta '-Tb' of the second transmission timing Ta 'and the second reception timing Tb' is greater than a second threshold Y, if the third difference absolute value Δ T is greater than the second threshold Y and meets a first preset condition, executing step 306, and if the preset parameters of the first communication mode and the second communication mode are traversed, the third difference absolute value Δ T is still less than or equal to the second threshold Y and does not meet the first preset condition, executing step 307.

Step 306: and when the third communication carrier parameter and the fourth communication carrier parameter meet a first preset condition, determining that the working carrier parameter of the first communication mode is the third communication carrier parameter, and the working carrier parameter of the second communication mode is the fourth communication carrier parameter.

If the third absolute difference value Δ T is greater than the second threshold Y, the adjusted second transmitting timing Ta 'and the second receiving timing Tb' satisfy a first preset condition, which indicates that the transmitting time slot of the adjusted first communication mode and the receiving time slot of the adjusted second communication mode are not coincident, and the second-order intermodulation product generated by the first communication mode and other communication modes such as 4G does not fall into the receiving time slot of the second communication mode WIFI, so that the WIFI does not interfere. Therefore, it can be determined that the transmission timing of the communication carrier of the first communication mode is the second transmission timing Ta 'and the reception timing of the second communication mode is the second reception timing Tb'.

In practical applications, this embodiment provides a way to traverse the preset parameters of the first communication mode and the second communication mode as follows: the first transmitting timing Ta may be adjusted to each timing Ta1 ', Ta 2', … … Tan 'in the preset parameters of the first communication mode in sequence to obtain a second transmitting timing Ta', the first receiving timing Tb may be adjusted to each timing Tb1 ', Tb 2', … … Tbm 'in the preset parameters of the second communication mode in sequence to obtain a second receiving timing Tb', and the second transmitting timing Ta 'and the second receiving timing Tb' which satisfy the first preset condition are respectively used as the working parameters of the first communication mode and the second communication mode, or when both m × n combinations of the second transmitting timing Ta 'and the second receiving timing Tb' do not satisfy the first preset condition, step 307 may be executed.

Step 307: and when the preset parameters of the first communication mode and the second communication mode are traversed and the first preset condition is not met, determining the working carrier parameters of the first communication mode and the second communication mode as communication carrier parameter values enabling the absolute value of the third difference to be the maximum.

When the first preset condition is not met after traversing each time sequence of the first communication mode transmitting time slot and each time sequence of the second communication mode receiving time slot, namely the third difference absolute value delta T is smaller than or equal to the second threshold value Y, at the moment, the transmitting time sequence of the first communication mode and the receiving time sequence of the second communication mode are respectively determined to be the time sequences enabling the third difference absolute value delta T to be maximum. Therefore, the superposition of the transmitting time slot of the first communication mode and the receiving time slot of the second communication mode can be ensured to be minimum, and even if second-order intermodulation products generated by the first communication mode and other communication modes such as 4G fall into the receiving time slot of the second communication mode WIFI, the energy is smaller, so that the interference on the work of the second communication mode WIFI is reduced, and the influence on the performance of a communication system is reduced.

In the communication method provided in the embodiment of the present invention, when a first transmission timing sequence of a first communication mode and a first reception timing sequence of a second communication mode satisfy a first preset condition, the first transmission timing sequence and the first reception timing sequence that satisfy the first preset condition are determined as transceiving timing sequences of the first communication mode and the second communication mode; when the first transmitting time sequence and the first receiving time sequence do not meet the first preset condition, the first transmitting time sequence (the first communication carrier parameter) is adjusted to be the second transmitting time sequence (the third communication carrier parameter), the first receiving time sequence (the second communication carrier parameter) is adjusted to be the second receiving time sequence (the fourth communication carrier parameter), and the second transmitting time sequence and the second receiving time sequence which meet the first preset condition or enable the absolute value of the third difference to be the maximum are determined to be the transmitting and receiving time sequences of the first communication mode and the second communication mode, so that intermodulation products generated between the first communication mode and other communication modes can not fall into the receiving time slot range of the second communication mode, or the energy of the intermodulation products falling into the receiving time slot range of the second communication mode is minimized, and the influence of the intermodulation products on the performance of the whole communication system is reduced.

Example four

Referring to fig. 4 and 5, block diagrams of two mobile terminals according to a fourth embodiment of the present invention are shown.

The mobile terminal of the embodiment of the present invention has a first communication mode and a second communication mode, and may include: a parameter obtaining module 501, configured to obtain a first communication carrier parameter corresponding to the first communication mode and a second communication carrier parameter corresponding to the second communication mode; the parameter adjusting module 502 is configured to adjust the first communication carrier parameter to be a third communication carrier parameter and adjust the second communication carrier parameter to be a fourth communication carrier parameter when the first communication carrier parameter and the second communication carrier parameter do not satisfy a first preset condition, where a communication interference amount generated between the third communication carrier and the fourth communication carrier is smaller than a communication interference amount generated between the first communication carrier and the second communication carrier.

The communication modes may include Sub-6GHz, 4G, WIFI and other communication modes. The parameter obtaining module 501 may obtain a first communication carrier parameter, which may be a frequency or a transmission/reception timing sequence of the first communication carrier, and obtain a second communication carrier parameter, which may be a frequency or a transmission/reception timing sequence of the second communication carrier. In practical applications, the frequency of the communication carrier is each frequency point within the operating frequency band, and the transmission/reception timing of the communication carrier is each timing of the transmission/reception time slot of the communication carrier.

Specifically, when the communication interference amount generated between the first communication carrier and the second communication carrier is greater than or equal to the preset threshold, the parameter adjusting module 502 adjusts the first communication carrier parameter to be the third communication carrier parameter, that is, the communication carrier of the first communication mode is adjusted from the first communication carrier to the third communication carrier, and the second communication carrier parameter is adjusted to be the fourth communication carrier parameter, that is, the communication carrier of the second communication mode is adjusted from the second communication carrier to the fourth communication carrier, so that the third communication carrier parameter and the fourth communication carrier parameter satisfy the first preset condition, or the communication interference amount generated between the third communication carrier and the fourth communication carrier is less than the communication interference amount generated between the first communication carrier and the second communication carrier, so that the communication interference amount generated between the communication carriers of the communication modes can be reduced.

The communication interference amount may be, for example, energy in which an intermodulation product generated between the communication carriers of the first communication mode and the second communication mode falls within a reception range (e.g., a reception band or a reception slot) of a communication carrier of another communication mode, such as a third communication mode, or energy in which an intermodulation product generated between the first communication mode and another communication mode, such as the third communication mode, falls within a reception range (e.g., a reception band or a reception slot) of the second communication mode, or the like.

Preferably, the parameter adjusting module 502 includes: a first unit 5021, configured to traverse preset parameters of the first communication mode and the second communication mode, adjust the first communication carrier parameter to be a third communication carrier parameter, and adjust the second communication carrier parameter to be a fourth communication carrier parameter; a second unit 5022, configured to determine that the working carrier parameter of the first communication mode is the third communication carrier parameter and the working carrier parameter of the second communication mode is the fourth communication carrier parameter when the third communication carrier parameter and the fourth communication carrier parameter satisfy the first preset condition.

When the first communication carrier parameter is a first carrier frequency of the first communication mode, the second communication carrier parameter is a second carrier frequency of the second communication mode, the mobile terminal further has a third communication mode, and the carrier frequency of the third communication mode is a designated frequency, the mobile terminal further includes: a first determining module 503, configured to determine whether a first difference absolute value between the first carrier frequency and the second carrier frequency and a second difference absolute value between the first carrier frequency and the second carrier frequency and the designated frequency are greater than a first threshold value before the parameter adjusting module adjusts the first communication carrier parameter to be a third communication carrier parameter and adjusts the second communication carrier parameter to be a fourth communication carrier parameter, and if so, the first preset condition is satisfied; if not, the first preset condition is not met.

Preferably, the mobile terminal may further include: a first determining module 504, configured to determine the working carrier parameter of the first communication mode and the second communication mode as the communication carrier parameter value that maximizes the second difference absolute value when the preset parameters of the first communication mode and the second communication mode are traversed and the first preset condition is not satisfied.

When the first communication carrier parameter is a first transmission timing sequence of the communication carrier in the first communication mode, and the second communication carrier parameter is a first reception timing sequence of the communication carrier in the second communication mode, the mobile terminal further includes: a second determining module 505, configured to determine whether a third absolute difference value between the first transmit timing and the first receive timing is greater than a second threshold before the parameter adjusting module adjusts the first communication carrier parameter to be a third communication carrier parameter and adjusts the second communication carrier parameter to be a fourth communication carrier parameter, and if so, satisfy the first preset condition; if not, the first preset condition is not met.

Preferably, the mobile terminal may further include: a second determining module 506, configured to determine the working carrier parameter of the first communication mode and the working carrier parameter of the second communication mode as the communication carrier parameter value that maximizes the third absolute difference value when the preset parameters of the first communication mode and the second communication mode are traversed and the first preset condition is not satisfied.

The mobile terminal provided by the embodiment of the present invention can implement each process implemented by the mobile terminal in any of the above method embodiments, and is not described herein again to avoid repetition.

In the mobile terminal provided by this embodiment, when the first communication carrier parameter and the second communication carrier parameter acquired by the parameter acquiring module do not satisfy the first preset condition, the parameter adjusting module adjusts the first communication carrier parameter to be the third communication carrier parameter and adjusts the second communication carrier parameter to be the fourth communication carrier parameter, and since the communication interference generated between the third communication carrier and the fourth communication carrier is smaller than the communication interference generated between the first communication carrier and the second communication carrier, the mobile terminal provided by this embodiment can reduce the influence of the communication interference on the performance of the whole communication system.
