The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The execution main body of the radio frequency interference processing method provided by the embodiment of the invention may be a radio frequency interference processing device provided by the embodiment of the invention, or a terminal (such as a notebook, a palm computer, a tablet computer, a smart phone, a vehicle-mounted smart device, a smart watch, and the like) integrated with the radio frequency interference processing device, and the radio frequency interference processing device may be implemented in a hardware or software manner.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a radio frequency interference processing method according to an embodiment of the present invention. The method comprises the following steps:
step S101, when detecting that the first communication module receives an instruction for executing a communication task, judging whether the second communication module is started; if yes, go to step S102; if not, go to step S104. The first communication module and the second communication module are different types of communication modules, and the working frequency bands of the first communication module and the second communication module are at least partially overlapped, namely the first communication module and the second communication module are mutual interference objects.
It can be understood that there is an overlapping frequency band interval between the operating frequency band of the second communication module and the operating frequency band of the first communication module. When detecting that the first communication module receives an instruction for executing a communication task, judging whether a second communication module is started in the terminal or not so as to eliminate an interference object.
It can be understood that, in a terminal development process, by obtaining operating frequency bands of a plurality of communication modules in a terminal, a frequency band interval in which every two communication modules, of which the operating frequency bands at least partially overlap, overlap exists in the plurality of communication modules, where every two communication modules, of which the operating frequency bands at least partially overlap, include a first communication module and a second communication module.
It is understood that a terminal often employs multiple communication technologies to meet the diversified communication requirements. The terminal may operate over a wired, wireless, or satellite-based communication system in which data is transmitted by frames or packets. For example, the plurality of Communication technologies may include Near Field Communication (NFC), bluetooth, WIreless local area network (WiFi), Global Positioning System (GPS), Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (FDD), TD-SCDMA, and TDD Frequency Division Duplex (TDD-SCDMA) in Long Term Evolution (LTE) Communication networks. The multiple communication technologies realize the functions of the communication technologies through corresponding communication modules, wherein each communication module corresponds to a working frequency band, and the working frequency band is a frequency band specified by an industry specification in the corresponding communication technology or a frequency band interval allowing working. It can be understood that there may be a situation where the operating frequency bands at least partially overlap between a plurality of communication modules in the terminal. In the terminal development process, whether the working frequency bands of the plurality of communication modules are at least partially overlapped is analyzed by obtaining the working frequency bands of the plurality of communication modules in the terminal, and a frequency band interval overlapped between every two communication modules with the at least partially overlapped working frequency bands in the plurality of communication modules is determined according to an analysis result, wherein every two communication modules with the overlapped working frequency bands comprise a first communication module and a second communication module. The obtained data and the analysis result may be recorded to establish a record table and store the record table in the terminal, for example, a record table about the frequency band interval overlapped among the communication modules is established, as shown in table 1, the working frequency bands of the communication modules and the interference objects interfering with each other are recorded, and the record table is recorded for the overlapped frequency band interval of every two communication modules overlapped by the working frequency bands.
TABLE 1
For example, as shown in table 1, the first communication module is GSM, the second communication module that is an interference object with GSM is WCDMA, and when detecting that the first communication module GSM receives an instruction to execute a communication task, it is determined whether the second communication module WCDMA is turned on; if yes, go to step S102; if not, go to step S104.
Step S102, detecting whether the current working frequencies of the first communication module and the second communication module are in an overlapped frequency band interval at the same time; if yes, go to step S103; if not, go to step S104.
It can be understood that, when the current operating frequencies of the first communication module and the second communication module are simultaneously in the overlapped frequency band interval, which indicates that the second communication module may affect the radio frequency signal of the first communication module, step S103 is executed; when the current operating frequencies of the first communication module and the second communication module are not in the overlapped frequency band interval at the same time, which indicates that the second communication module does not affect the radio frequency signal of the first communication module, step S104 is executed.
For example, the first communication module is GSM900, the second communication module is WCDMA, an overlapped frequency band interval of the GSM900 and the WCDMA is B8, when the current operating frequency of the GSM900 is in B8 and the current operating frequency of the WCDMA is in B8, the current operating frequencies of the GSM900 and the WCDMA of the first communication module are simultaneously in the overlapped frequency band interval B8, so that radio frequency interference exists between the GSM900 and the WCDMA, and the two modules cannot coexist in the same operating period to avoid the interference.
For example, the first communication module is GSM900, the second communication module is WCDMA, the overlapped frequency band interval of GSM900 and WCDMA is B8, when the current operating frequency of GSM900 is in B8 and the current operating frequency of WCDMA is in B3, then GSM and WCDMA do not exist in the overlapped frequency band interval at the same time, there is no radio frequency interference between them, and both may coexist in the same operating period.
And step S103, performing radio frequency interference processing by closing the second communication module.
It can be understood that, when the current operating frequencies of the first communication module and the second communication module are simultaneously in the overlapped frequency band interval, during the period when the first communication module executes the communication task, the second communication module needs to be closed to perform the radio frequency interference processing, so as to eliminate the radio frequency interference from the second communication module.
Step S104, allowing the first communication module and the second communication module to operate simultaneously.
It can be understood that, when the current operating frequencies of the first communication module and the second communication module are not in the overlapped frequency band interval at the same time, it indicates that there is no radio frequency interference between the first communication module and the second communication module, and the first communication module and the second communication module may be allowed to operate at the same time.
In some embodiments, before the radio frequency interference processing by turning off the second communication module, the method further includes:
and judging whether the priority of the first communication module is greater than that of the second communication module.
In some embodiments, the performing the radio frequency interference processing by turning off the second communication module includes:
when the priority of the first communication module is higher than that of the second communication module, controlling the first communication module to execute a communication task, and closing the second communication module during the communication task executed by the first communication module; or
And when the priority of the first communication module is smaller than that of the second communication module, closing the second communication module after the second communication module finishes execution.
In some embodiments, the method further comprises:
and when the current working frequencies of the first communication module and the second communication module are not in the overlapped frequency band interval at the same time, allowing the first communication module and the second communication module to operate at the same time.
Before the radio frequency interference processing is performed by closing the second communication module, the method further includes: and judging whether the radio frequency signal intensity of the first communication module is smaller than a threshold value.
In some embodiments, the performing the radio frequency interference processing by turning off the second communication module includes:
when the radio frequency signal intensity of the first communication module is smaller than a threshold value, the second communication module is closed during the first communication module executes a communication task.
In some embodiments, after the determining whether the radio frequency signal strength of the first communication module is less than a threshold, the method further includes:
when the radio frequency signal intensity of the first communication module is larger than a threshold value, the first communication module and the second communication module are allowed to operate simultaneously.
All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
Referring to fig. 2, fig. 2 is another flow chart of a radio frequency interference processing method according to an embodiment of the present invention. The method comprises the following steps:
step S201, when detecting that the first communication module receives an instruction for executing a communication task, judging whether the second communication module is started; if yes, go to step S202; if not, go to step S206. The first communication module and the second communication module are different types of communication modules, and the working frequency bands of the first communication module and the second communication module are at least partially overlapped.
It can be understood that there is an overlapping frequency band interval between the operating frequency band of the second communication module and the operating frequency band of the first communication module. When detecting that the first communication module receives an instruction for executing a communication task, judging whether a second communication module is started in the terminal or not so as to eliminate an interference object.
It can be understood that, in a terminal development process, a frequency band interval in which every two communication modules with at least partially overlapped working frequency bands exist in the plurality of communication modules is determined by acquiring the working frequency bands of the plurality of communication modules in the terminal, where every two communication modules with at least partially overlapped working frequency bands include a first communication module and a second communication module, that is, the first communication module and the second communication module are mutual interference objects.
For example, as shown in table 1, the first communication module is FDD-LTE, the second communication module that is an interference object with FDD-LTE is WCDMA, and when detecting that the first communication module FDD-LTE receives an instruction to execute a communication task, it determines whether the second communication module WCDMA is turned on; if yes, go to step S202; if not, go to step S206.
Step S202, detecting whether the current working frequencies of the first communication module and the second communication module are in an overlapped frequency band interval at the same time; if yes, go to step S203; if not, go to step S206.
It can be understood that, when the current operating frequencies of the first communication module and the second communication module are simultaneously in the overlapped frequency band interval, which indicates that the second communication module may affect the radio frequency signal of the first communication module, step S203 is executed; when the current operating frequencies of the first communication module and the second communication module are not in the overlapped frequency band interval at the same time, which indicates that the second communication module does not affect the radio frequency signal of the first communication module, step S206 is executed.
For example, the first communication module is FDD-LTE, the second communication module is WCDMA, an overlapped frequency band interval of the FDD-LTE and the WCDMA is B1 or B3, when the current working frequency of the FDD-LTE is within B1 and the current working frequency of the WCDMA is within B1, the current working frequency of the FDD-LTE and the WCDMA of the first communication module are simultaneously within an overlapped frequency band interval B1, radio frequency interference exists between the FDD-LTE and the WCDMA, and the FDD-LTE and the WCDMA cannot coexist in the same working period to avoid interference.
For example, the first communication module is FDD-LTE, the second communication module is WCDMA, an overlapped frequency band interval of FDD-LTE and WCDMA is B1 or B3, when the current working frequency of FDD-LTE is in B7 and the current working frequency of WCDMA is in B5, the current working frequency of FDD-LTE and WCDMA of the first communication module is not in the overlapped frequency band interval B1 or B3, no radio frequency interference exists between FDD-LTE and WCDMA, and the FDD-LTE and WCDMA can coexist in the same working period.
Step S203, judging whether the priority of the first communication module is greater than the priority of the second communication module; if yes, go to step S204; if not, go to step S205.
It can be understood that, before the first communication module starts to execute the communication task, the priority of the first communication module and the priority of the second communication module are determined, and the order of executing the communication task among the modules is determined according to the priority.
Step S204, controlling the first communication module to execute a communication task, and closing the second communication module during the communication task executed by the first communication module.
It can be understood that, when the priority of the first communication module is greater than the priority of the second communication module, and the task of the first communication module needs to be executed preferentially, the first communication module is controlled to start executing the communication task, and the second communication module is temporarily turned off to interrupt the task currently being executed by the second communication module, and after waiting for the communication task of the first communication module to be executed completely, the second communication module is turned on again to enable the second communication module to continue executing the task that was temporarily interrupted during the execution of the first communication module.
Step S205, closing the second communication module after the second communication module is executed.
It can be understood that, when the priority of the first communication module is lower than the priority of the second communication module, and the task of the second communication module needs to be executed preferentially, the first communication module is controlled to enter a waiting process, and the second communication module does not interrupt execution, and the second communication module is closed after the second communication module is executed, and finally the execution process of the first communication module is entered.
Step S206, allowing the first communication module and the second communication module to operate simultaneously.
It can be understood that, when the current operating frequencies of the first communication module and the second communication module are not in the overlapped frequency band interval at the same time, it indicates that there is no radio frequency interference between the first communication module and the second communication module, and the first communication module and the second communication module may be allowed to operate at the same time.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a radio frequency interference processing method according to an embodiment of the present invention. The method comprises the following steps:
step S301, when detecting that the first communication module receives an instruction for executing a communication task, judging whether the second communication module is started; if yes, go to step S302; if not, step S305 is executed.
It can be understood that there is an overlapping frequency band interval between the operating frequency band of the second communication module and the operating frequency band of the first communication module. When detecting that a first communication module receives an instruction for executing a communication task, judging whether a second communication module is started in a terminal or not so as to eliminate an interference object, namely the first communication module and the second communication module are mutual interference objects.
It can be understood that, in a terminal development process, by obtaining operating frequency bands of a plurality of communication modules in a terminal, a frequency band interval in which every two communication modules, of which the operating frequency bands at least partially overlap, overlap exists in the plurality of communication modules, where every two communication modules, of which the operating frequency bands at least partially overlap, include a first communication module and a second communication module.
Step S302, detecting whether the current working frequencies of the first communication module and the second communication module are in an overlapped frequency band interval at the same time; if yes, go to step S303; if not, step S305 is executed.
It can be understood that, when the current operating frequencies of the first communication module and the second communication module are simultaneously in the overlapped frequency band interval, which indicates that the second communication module may affect the radio frequency signal of the first communication module, step S303 is executed; when the current operating frequencies of the first communication module and the second communication module are not in the overlapped frequency band interval at the same time, which indicates that the second communication module does not affect the radio frequency signal of the first communication module, step S305 is executed.
Step S303, judging whether the radio frequency signal intensity of the first communication module is smaller than a threshold value; if yes, go to step S304; if not, step S305 is executed.
It can be understood that, although the second communication module may affect the radio frequency signal of the first communication module when the current operating frequencies of the first communication module and the second communication module are simultaneously in the overlapped frequency band interval, when the degrees of radio frequency interference are different, it is further required to further determine whether the strength of the radio frequency signal of the first communication module is smaller than a threshold value for the convenience of the user; if the radio frequency signal intensity of the first communication module is smaller than the threshold, it indicates that the second communication module has great interference to the first communication module, and needs to perform interference processing, and the two modules cannot coexist in the same working period, then step S304 is executed; if the radio frequency signal intensity of the first communication module is greater than the threshold, it indicates that the interference of the second communication module to the first communication module is small, and the two modules can coexist in the same working period, then step S305 is executed.
Step S304, turning off the second communication module during the communication task executed by the first communication module.
For example, the first communication module is controlled to execute a communication task, the second communication module is temporarily turned off during the communication task executed by the first communication module, so as to interrupt the task currently executed by the second communication module, and the second communication module is turned on after waiting for the communication task of the first communication module to be executed completely, so that the second communication module continues to execute the task temporarily interrupted during the execution of the first communication module.
Step S305, allowing the first communication module and the second communication module to operate simultaneously.
It can be understood that, when the current operating frequencies of the first communication module and the second communication module are not in the overlapped frequency band interval at the same time, it indicates that there is no radio frequency interference between the first communication module and the second communication module, and the first communication module and the second communication module may be allowed to operate at the same time.
It can be understood that, if the strength of the radio frequency signal of the first communication module is greater than the threshold, it indicates that the interference of the second communication module to the first communication module is small, and the first communication module and the second communication module may be allowed to operate simultaneously.
According to the embodiment of the invention, whether a second communication module is started is judged by detecting that a first communication module receives an instruction for executing a communication task, wherein the first communication module and the second communication module are different types of communication modules, the working frequency ranges of the first communication module and the second communication module are at least partially overlapped, and when the second communication module is judged to be started and the current working frequencies of the first communication module and the second communication module are detected to be in the overlapped frequency range, the second communication module is closed to carry out radio frequency interference processing, so that the interference from other communication modules with the overlapped frequency range between the first communication module and the second communication module is reduced in the running period of the first communication module, and the communication quality is improved.
