It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Please refer to fig. 1, which is a flowchart illustrating a multimode communication method according to an embodiment of the present application. In the present embodiment, the method for multimode communication in the present application includes steps S110 to S120.
S110: monitoring whether interference occurs between the narrowband communication and the broadband communication.
In the process of communication of the mobile terminal, monitoring whether interference occurs between narrowband communication and broadband communication is achieved by monitoring the frequency of narrowband communication and the frequency of broadband communication and comparing the relationship between the frequency of narrowband communication and the frequency of broadband communication or the relationship between the frequency of narrowband communication and the bandwidth of broadband communication through calculation (please refer to the following text for detailed explanation of calculation and comparison). Furthermore, the interference generated between the narrowband communication and the broadband communication is co-channel interference, that is, a conflict occurs between the frequency of the current narrowband communication and the frequency of the broadband communication, so that by judging that the intersection exists between the narrowband communication frequency and the bandwidth range of the broadband communication, it can be judged whether communication interference affecting the broadband communication quality is generated between the current narrowband communication and the broadband communication.
S120: when interference between narrow-band communication and broadband communication is detected, the driving power of a narrow-band power amplifier is reduced and/or harmonic suppression of the narrow-band is increased to avoid the interference.
When the interference between the narrowband communication and the broadband communication is monitored in step S110, the driving power of the narrowband power amplifier is reduced and the harmonic suppression of the narrowband is increased to avoid the interference generated between the current narrowband communication and the broadband communication, so as to simultaneously ensure the quality of the narrowband communication and the broadband communication. It is understood that in other embodiments, the above interference can be avoided by reducing the driving power of the narrowband power amplifier or increasing or decreasing the harmonic suppression of the narrowband.
In one embodiment, the driving power of the narrow-band power amplifier is reduced by the power control unit, i.e. the power control unit is switched in to reduce the driving power of the power amplifier. It is understood that in other embodiments, the driving power of the narrow-band power amplifier may be reduced in other manners, which are not described in detail herein. The power control component provided by the present application includes any one of a fixed attenuator, an electronic attenuator, an automatic gain control or a voltage divider, specifically according to the setting in the mobile terminal. In another embodiment, step S120 is to add harmonic rejection of a narrow band by accessing a harmonic rejection component. The harmonic suppression component refers to a device capable of reducing harmonics, and may be any one of a band-pass filter, a band-stop filter, a high-pass filter, a wave trap, an attenuator, and a third type of circuit introduced through a switch/PIN tube, and the like, which is not limited herein.
Further, please refer to fig. 2, which is a flowchart illustrating a multimode communication method according to an embodiment of the present invention. In the current embodiment, when the interference between the narrowband communication and the broadband communication is monitored, a push notification is further formed for the user to select whether to avoid the interference and select a communication category maintaining high quality. Wherein the content of the first and second substances,
s110: monitoring whether interference occurs between the narrowband communication and the broadband communication.
S202: and when the interference between the narrow-band communication and the broadband communication is monitored, forming a push notification for a user to select whether to avoid the interference.
When the interference between the narrow-band communication and the broadband communication is monitored, a push notification is formed to notify a user that the communication interference between the narrow-band communication and the broadband communication occurs currently, and a window is provided for the user to select whether the communication interference needs to be avoided or not, so that the user can select whether the communication interference needs to be avoided or not to obtain better broadband communication quality.
Specifically, the push notification is to display interference generated by frequency conflict between the narrowband communication and the broadband communication on a screen to inform a user that the interference is generated by the narrowband communication and the broadband communication in the current communication process, prompt the user to select to avoid the generated interference, give the user a corresponding interference avoidance option and a corresponding avoidance rejection option, and the content of a specific option is not limited, and the form of the formed push notification is not limited.
Further, in an embodiment, when it is determined that the narrowband communication and the broadband communication interfere with each other, a window-type push notification pops up on a screen, prompting a user that communication interference affecting the current broadband communication quality is generated due to frequency conflict between the narrowband communication and the broadband communication (the difference between the frequency values of the narrowband communication and the broadband communication is less than a preset threshold), and prompting the user whether to select avoidance interference or not.
S203: when the user chooses to avoid the interference, the drive power of the narrowband power amplifier is reduced and/or the harmonic rejection of the narrowband is increased.
When a user selects to avoid interference generated by narrow-band communication and broadband communication, the driving power of a narrow-band power amplifier is reduced and/or harmonic suppression of the narrow band is increased to avoid the interference. Furthermore, the preset instruction is sent to the preset circuit module and/or the preset electronic component, so that the driving power of the narrowband power amplifier is reduced and/or the harmonic suppression of the narrowband is increased, the interference caused by the conflict between the narrowband frequency and the broadband frequency is solved, and the quality of the narrowband communication and the broadband communication is ensured while the narrowband communication and the broadband communication are maintained. In the current embodiment, the communication interference which cannot be seen by naked eyes and is not easy to be perceived by a user is informed to the user in a push notification mode, so that a technical scheme that whether avoidance or avoidance refusal can be selected according to actual needs of the user can be well provided for the user, and the user experience is improved.
It can be understood that after the user selects to avoid interference, the user can also select to cancel the avoidance interference again after sending the preset instruction to the preset circuit module and/or the preset electronic component to reduce the driving power of the power amplifier and/or increase harmonic suppression, so as to ensure higher-quality narrow-band communication or broadband communication.
In another embodiment, please refer to fig. 3, in the current embodiment, after step S202, step S301 is further included.
S110: monitoring whether interference occurs between the narrowband communication and the broadband communication.
S202: and when the interference between the narrow-band communication and the broadband communication is monitored, forming a push notification for a user to select whether to avoid the interference.
S301: when the user selects to refuse to avoid the interference, the interference of the narrow-band communication to the broadband communication is prompted to be serious, and the performance of the broadband communication is influenced. As can be seen from the above, when it is determined in step S110 that the current narrowband communication and the current broadband communication generate serious interference, but the user chooses to refuse to avoid the interference, it can be known from the characteristics of the narrowband communication and the broadband communication that the narrowband communication has a serious influence on the quality of the broadband communication, and the influence of the interference generated by the user on the quality of the broadband communication is notified through step S301, so that the user can further determine the interference according to actual needs. When the mobile terminal does not have data service at this time, the use of the user is not affected. If the mobile terminal has data service at the moment, the mobile terminal is used for prompting the user to reselect to avoid communication interference or to select one of narrow-band communication and broadband communication for high-quality communication.
Further, after the user selects to refuse to avoid the interference, the method further comprises the following steps: the user is prompted to select one of narrowband communication and broadband communication for high performance communication. From the above, when the narrowband communication generates serious interference to the broadband communication, under the condition that the user chooses to refuse to avoid the interference, the user is continuously prompted to select one of the narrowband communication and the broadband communication for high-performance communication, according to the selection of the user, the communication type selected by the user is kept to be continuously communicated, and the other communication is stopped. It will be appreciated that for convenience of use by the user, the terminated communication type may be automatically initiated when it is detected that the narrowband communication and the broadband communication of the terminal device are no longer interfering, or the user may be prompted that the narrowband communication and the broadband communication are currently available simultaneously.
In one embodiment, it may be preset that: after prompting the user to select one of the narrow-band communication and the broadband communication for high-performance communication, when the preset time is exceeded and the user still does not select one of the narrow-band communication and the broadband communication for high-performance communication, the narrow-band communication is automatically selected for high-performance communication, and the broadband communication is terminated.
In another embodiment, it can also be preset that: when the preset time is exceeded and the user does not select one of the narrow-band communication and the broadband communication for high-performance communication, the broadband communication is automatically selected for high-quality communication, and the narrow-band communication is terminated.
It is understood that in other embodiments, the communication level may be preset for narrowband communication and broadband communication according to different application scenarios. When the communication level is preset according to different application scenes, the mobile terminal can automatically select the communication with higher limited level according to the preset communication level to continue to maintain high-quality communication after the user refuses to avoid communication interference. Such as:
in an embodiment, when the current mobile terminal is a mobile terminal for communication use when a blasting task is executed, because the requirement for high-quality narrowband communication is more important in the blasting process, the priority level of narrowband communication is set to be high-level communication, and when communication interference occurs due to frequency conflict between narrowband communication and broadband communication and communication quality is affected, the broadband communication is automatically terminated after a user refuses to avoid the communication interference, so that high-quality narrowband communication is maintained, and the communication quality of the mobile terminal can meet the requirement of the current application scene.
In another embodiment, when the application scene of a certain mobile terminal is a scene requiring a high-quality picture, the broadband communication is set to be a higher-level communication according to the requirement, so that the preset high-level broadband communication can be automatically selected after the user refuses or does not select the terminated communication type for more than the preset time, and the high-quality picture can be timely provided.
It can be understood that the priority level of the communication may be adjusted and set according to different application scenarios, for example, when the application scenarios of the mobile terminal are complex and changeable, the user may adjust the priority level of the communication mode according to the current needs, and specific details are not described herein.
Further, please refer to fig. 4, which is a flowchart illustrating a multimode communication method according to an embodiment of the present invention. Wherein the step of reducing the drive power of the narrow band power amplifier and/or increasing the harmonic suppression further comprises: s401 to S403. Wherein the content of the first and second substances,
s401: and determining the harmonic wave type and/or the communication system of the narrow-band communication.
When a user selects to avoid interference, the harmonic wave type and the communication system of narrowband communication need to be further determined. The harmonic category of the narrow-band communication comprises: fundamental, second harmonic, third harmonic, fourth harmonic, and the like. The communication systems mainly include: FM, DMR, Tetra, P25, and the like.
S402: and calculating the power value of the power amplifier required to be reduced according to the harmonic wave type and/or the communication system of the narrow-band communication.
The power value of the power amplifier (power amplifier) to be reduced is calculated based on the determination result of the harmonic type and/or the communication system of the narrowband communication determined in step 401. Specifically, since the magnitude of power reduction of the power amplifier is affected when the types of the harmonic waves of the narrowband communication are different, the power values of the power amplifier required to be reduced are also different according to the difference of the current communication systems of the terminal devices. Therefore, the power value of the power amplifier required to be reduced is calculated according to the difference of the harmonic wave types of the current narrow-band communication and the difference of the communication systems, the power change of the power amplifier can be controlled more accurately, the power of the power amplifier is reduced, the harmonic frequency of the narrow-band communication is ensured not to influence the broadband communication, and meanwhile, the quality of the narrow-band communication broadband communication is also ensured accurately.
S403: and sending a preset instruction to reduce the power of the power amplifier according to the calculated result.
Based on the power value of the power amplifier required to be reduced calculated in the step 402, a corresponding preset instruction is generated and sent to a corresponding circuit module or an electronic device, so as to reduce the power of the power amplifier or the power of other circuit modules having the same function as the power amplifier, thereby reducing the harmonic frequency of the narrow-band communication. The preset instruction is sent to the corresponding circuit component or the circuit module in the form of an electric signal. As described above, the electronic component refers to a device or a power control component capable of directly or indirectly adjusting power of a power amplifier, and specifically includes: any one of a fixed attenuator, an electronic attenuator, an automatic gain control or voltage dividing device, and the like.
Further, referring to fig. 5, fig. 5 is a flowchart illustrating steps of reducing the driving power of the narrow-band power amplifier and/or increasing the harmonic suppression of the narrow-band in another embodiment. Specifically, S501 to S503 are included. Wherein the content of the first and second substances,
s501: and determining the harmonic wave type and/or the communication system of the narrow-band communication. Step S501 is the same as step S401, and both the harmonic type and/or the communication system of the narrowband communication are determined, which is not described in detail herein.
S502: and calculating the amount of harmonic suppression required to be added according to the harmonic type and/or the communication system of the narrow-band communication.
And calculating the amount of harmonic suppression required to be added according to the narrowband communication harmonic species and/or the communication system obtained in the step. As the name implies, harmonic suppression is used to suppress harmonics, thereby achieving the goal of reducing the frequency of the communication harmonics. When the types of the narrowband communication harmonics are different, it is necessary to increase different amounts of harmonic suppression when the broadband communication quality is not affected by suppressing the narrowband harmonic frequency, and therefore, in order to more accurately suppress the narrowband frequency, it is necessary to increase different amounts of harmonic suppression according to the types of the narrowband communication harmonics. Similarly, the amount of harmonic suppression required to be added is different for different current communication systems of the terminal device, so in order to more accurately realize the suppression of the narrowband frequency, the amount of harmonic suppression required to be added needs to be calculated according to different communication systems except the harmonic type of the reference narrowband communication. It is understood that, in different embodiments, the amount of harmonic suppression required to be added may be calculated according to only the harmonic type of the narrowband communication, or according to only the communication system, or according to both the harmonic type of the narrowband communication and the communication system.
And S503, sending a preset instruction, and increasing the harmonic suppression according to the calculation result to avoid interference.
According to the harmonic suppression amount calculated in the step S502, a preset instruction is sent, and harmonic suppression corresponding to the harmonic suppression amount is increased, or harmonic suppression of a narrow band is increased by accessing a harmonic suppression component, so as to achieve interference avoidance. The calculated harmonic suppression amount can more accurately avoid communication interference and ensure the requirement of narrow-band communication.
Further, please refer to fig. 6, which is a flowchart illustrating a multimode communication method according to an embodiment of the present invention. In the present embodiment, how to monitor whether the narrowband communication and the wideband communication interfere with each other is further described, wherein the step S110 further includes steps S601 to S604. Wherein the content of the first and second substances,
specifically, step S601: reading narrow band frequencies and wide band frequencies.
In one embodiment, the narrowband frequency is a narrowband communication fundamental frequency or a narrowband communication harmonic frequency; the broadband frequency is the lowest frequency and the highest frequency of the broadband communication, and may also be the frequency at which the broadband communication is currently operating. Here, the manner of reading the narrowband frequency and the manner of reading the wideband frequency are not limited at all.
In an embodiment, the read narrowband frequency is a narrowband communication fundamental frequency, and then a corresponding harmonic frequency (e.g., a second harmonic frequency, a third harmonic frequency, etc.) is calculated according to the read narrowband communication fundamental frequency by a predetermined calculation method. It is to be understood that the narrowband frequencies include a narrowband communication fundamental frequency and a narrowband communication harmonic frequency, and when one of the narrowband frequencies is read, the other can be calculated from a relationship therebetween, and when the narrowband communication fundamental frequency is read, the narrowband communication harmonic frequency can be calculated from the narrowband communication fundamental frequency. The specific one of the narrowband frequencies read in step S601 may be set in advance, and is not particularly limited herein.
In another embodiment, the read narrowband frequency is not a narrowband communication harmonic frequency, and may be directly read to a second harmonic frequency, a third harmonic frequency, or the like according to the actual situation, where no limitation is made on whether to read a narrowband communication fundamental frequency before reading the narrowband communication harmonic frequency.
S602: a bandwidth range of the wideband communication is calculated from the wideband frequency.
Further, step S601 is followed by: and calculating the bandwidth range of the broadband communication according to the read broadband frequency value. Based on the read lowest frequency and highest frequency of the broadband communication, calculating the bandwidth range of the broadband communication to judge whether the communication interference is generated between the narrowband communication and the broadband communication. It is to be understood that, since the method for calculating the bandwidth range of the broadband communication is not exclusive, the method for calculating the bandwidth range of the broadband communication is not limited herein, and the bandwidth of the broadband communication may be indirectly calculated in other manners.
S603: and judging whether the narrowband frequency and the harmonic thereof intersect with the bandwidth range of the broadband communication so as to judge whether the interference occurs.
Specifically, based on the narrowband frequency and the wideband bandwidth range obtained in step S601 and step S602, it is determined whether communication interference affecting communication quality occurs in the currently monitored narrowband communication and wideband communication. The narrowband frequency (or narrowband harmonic frequency) is an expression communication frequency value, the bandwidth range of the broadband communication is an expression frequency range value, and whether frequency conflict occurs between the narrowband frequency and the broadband frequency is judged by judging whether intersection exists between the narrowband frequency and the harmonic frequency thereof and the current broadband communication bandwidth, so that communication interference is generated to influence the communication quality. It will be appreciated that the relationship between the narrowband frequencies or harmonics thereof and the wideband communication bandwidth range includes: the narrow-band frequency belongs to the broadband communication bandwidth range, namely the minimum value-x of the broadband frequency is not less than the maximum value + x of the broadband frequency (the size of x is adjusted according to the actual condition of a specific product, and the minimum value and the maximum value of the broadband frequency are determined according to the broadband frequency and the corresponding bandwidth range); similarly, when the harmonic wave of the narrow-band communication belongs to the bandwidth range of the wide-band communication, namely the minimum value-x of the wide-band frequency is less than or equal to the maximum value + x of the narrow-band harmonic wave frequency. Of course, the relationship between the narrowband frequency and its harmonics and the wideband communication bandwidth also includes: the narrowband frequency values and their harmonics are not within the wideband communication bandwidth. It is to be understood that the above-described method for determining whether interference occurs between narrowband and wideband communications is only one example implementation manner of the present disclosure, and those skilled in the art may also use other implementation manners to implement the function of determining whether interference occurs between narrowband and wideband communications.
S604: and when the narrowband communication frequency and the harmonic thereof intersect with the bandwidth range of the broadband communication, judging that the interference occurs.
It is understood that the frequency of the narrowband communication may be the calculated frequency of the harmonic point, or may be the frequency of the narrowband communication fundamental wave. The intersection of the frequency of the narrowband communication and the bandwidth range of the wideband communication may be specifically understood as follows: the frequency of the narrow-band communication belongs to the frequency range represented by the broadband communication bandwidth, namely when the following conditions are satisfied: the minimum value-x of the broadband frequency is less than or equal to the maximum value + x of the broadband frequency (the size of x is adjusted according to the actual situation of a specific product, and the minimum value and the maximum value of the broadband frequency are determined according to the broadband frequency and the corresponding bandwidth range), then it is determined that communication interference occurs between the narrowband communication and the broadband communication, or it can be seen from the perspective of the broadband communication or the perspective of the narrowband communication, that is, it is seen from the perspective of the broadband communication: communication interference affecting the broadband communication quality is generated due to the fact that the frequency of the narrowband communication is too high; when viewed from the narrow-band communication, communication interference affecting the quality of the current narrow-band communication is generated due to frequency collision between the frequency of the wideband communication and the frequency of the narrow-band communication.
In the current embodiment, when the narrowband communication frequency and the wideband communication have an intersection, or the narrowband communication harmonic and the wideband communication have an intersection, or the narrowband communication frequency and the harmonic thereof both have an intersection with the wideband communication, it can be determined that interference is generated between the narrowband communication and the wideband communication, and it is necessary to avoid or prompt a user to select whether to avoid.
Referring to fig. 7, in another embodiment, the step S110 includes steps S701 to S703.
S701: the narrowband and wideband frequencies are read and/or calculated.
Step S701 is to directly read the narrowband frequency and the wideband frequency in an embodiment, and in another embodiment, it is preset that the narrowband communication harmonic frequency needs to be acquired, and then the narrowband fundamental frequency is read and then the narrowband communication harmonic frequency is calculated. Meanwhile, the wideband frequency needs to be read or calculated, and the calculation of the narrowband harmonic frequency and the wideband frequency is not limited at all.
S702: and calculating the difference value of the narrow-band frequency and the wide-band frequency to obtain a frequency difference value, and comparing the frequency difference value with a preset threshold value. Where the frequency difference is the absolute value of the difference.
In step S702, a difference between the narrowband frequency and the wideband frequency obtained in step S701 is calculated to obtain a frequency difference, and the frequency difference is compared with a preset threshold. Wherein the frequency difference is an absolute value of a difference between the narrowband frequency and the wideband frequency, and the frequency difference is obtained by correcting the calculated difference. The frequency difference here refers to the difference between the narrowband frequency and the wideband frequency, and is used to indicate that the narrowband frequency is far from the wideband frequency and is a positive value.
And comparing the frequency difference obtained by positive sampling with a preset threshold value. The preset threshold is a difference value used for representing the distance between the narrow-band frequency and the broadband frequency, and is generally a critical difference value when the narrow-band communication generates communication interference on the broadband communication, and specifically, the preset threshold can be set and adjusted according to different scene needs, and the preset threshold is not limited at all.
S703: and when the frequency difference value is smaller than or equal to a preset threshold value, judging that the interference is generated.
In the calculation that the frequency difference value is larger or smaller than the preset threshold value, when the obtained frequency difference value is smaller than or equal to the preset threshold value, the communication interference is judged to be generated at the moment, namely the frequency of the narrow-band communication is close to the frequency of the broadband communication at the moment, the interference of a broadband system is generated on the broadband communication, the quality of the broadband communication is influenced, and the user experience is influenced.
