According to a first aspect of the present invention, there is provided a method for controlling an antenna of a mobile terminal, the mobile terminal including a plurality of antennas, comprising: step 1, selecting the antenna with the current received signal strength greater than the strength threshold value from all the opened antennas and taking the selected antenna as a selected target, and then closing the unselected antennas; and 2, selecting the antennas with approximately consistent current received signal strength from all the selected objects, using the antennas as final objects for transmitting data together, and then closing the unselected selected objects, wherein the approximately consistent current received signal strength is defined as that the absolute value of the difference of the current received signal strength between the antennas is not greater than a difference threshold.
Further, the step 2 further comprises: and when the antenna with approximately consistent current received signal strength does not exist in all the selected targets, selecting one antenna with the highest current received signal strength from all the selected targets as a final target for transmitting data, and then closing the unselected selected targets.
Further, the step 2 specifically includes: step 201, sequencing all the selected targets according to the intensity of the current received signal, and assigning a value 1 to a variable i; step 202, extracting the ith selected target from all the selected targets as a comparison target, and then judging whether there is the selected target of which the current received signal is not less than a first set value and not more than a second set value in all the selected targets with serial numbers more than i, wherein the first set value is equal to the current received signal strength of the comparison target, and the second set value is equal to the sum of the current received signal strength of the comparison target and a difference threshold; step 203, if the result of the determination in the step 202 is yes, selecting the selected target and the comparison target whose current received signal strength is not less than the first setting value nor greater than the second setting value as the antennas whose current received signal strengths are approximately consistent, and using them together as a final target for data transmission, and then closing the unselected selected target; step 204, if the judgment result of the step 202 is negative, judging whether i is equal to the total number of the selected targets; step 205, if the judgment result of the step 204 is negative, assigning the number of the results of i +1 to i and returning to the step 202; step 206, if the result of the determination in the step 204 is yes, selecting one of the antennas with the highest current received signal strength from all the selected targets as a final target for data transmission, and then closing the unselected selected targets.
Further, the intensity threshold is equal to the sum of the digital signal threshold of the antenna and a compensation value, wherein the value range of the compensation value is 15-25 dbm.
Further, the compensation value is 20 dbm.
Further, the difference threshold value is 3-6 db.
Further, the antenna is a millimeter wave antenna.
Further, the mobile terminal is a mobile phone, a smart watch or a flat computer.
According to a second aspect of the present invention, there is provided a mobile terminal comprising a memory for storing computer program instructions and a processor for executing the computer program instructions, wherein the processor is configured to implement the control method described above when executing the computer program instructions.
According to a third aspect of the present invention, there is provided a computer readable medium having stored thereon computer program instructions executable by a processor to implement the control method described above.
As can be seen from the foregoing, the present invention provides a method for controlling antennas of a mobile terminal, a mobile terminal capable of implementing the method, and a computer readable medium storing the method, wherein the method is capable of selecting antennas having received signal strength greater than a strength threshold value from all turned-on antennas, selecting the antennas as selected targets, and then turning off unselected antennas. The inventor finds out after great efforts that, because the electromagnetic wave in the millimeter wave band has strong straight-line propagation and extremely weak diffraction capability, a plurality of antennas are usually used to form a MIMO (large-scale antenna array) mode in the mobile terminal to improve the communicable range, but when an obstacle blocks the antenna, the signal strength received by the antenna is significantly deteriorated, so that the antenna cannot be used for transmitting data and continuously consumes energy, and therefore, the antenna not greater than the intensity threshold is turned off, so that the energy consumption of the antenna of the mobile terminal can be effectively reduced. The control method can also select antennas with approximately consistent current received signal strength from all the selected targets, and the antennas are used as final targets for transmitting data together, and then the unselected targets are closed. Because the MIMO (large-scale antenna array) mode mainly gains the transmission data of the antennas through space diversity, and the premise of realizing the space diversity gain is that the signal strengths are approximately consistent, that is, when the absolute value of the difference between the signal strengths received by the two antennas is greater than the difference threshold, the space diversity gain cannot be realized between the two antennas, and when the signal strengths received by the antennas are approximately consistent, a space diversity gain effect can be generated between the antennas, so as to improve the data throughput and the mobile communication quality of the mobile terminal, so that the energy consumption of the mobile terminal can be further reduced by turning off the unselected antennas after selecting the antennas whose current received signal strengths are approximately consistent. By the mode, the control method of the mobile terminal antenna, the mobile terminal and the computer readable medium can solve the problem of high energy consumption of the mobile terminal, meet the requirement of the mobile terminal on data throughput, ensure the mobile communication quality of the mobile terminal and reduce the energy consumption of the mobile terminal during the use of mobile communication.

Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1 is a flowchart of a method for controlling an antenna of a mobile terminal according to an embodiment of the present invention. As shown in fig. 1, the present invention provides a method for controlling an antenna of a mobile terminal, wherein the mobile terminal can be a mobile phone, a smart watch, or a tablet computer, and includes a plurality of antennas. The antenna is preferably a millimeter wave antenna, millimeter waves typically referring to electromagnetic waves having a frequency in the range of 30GHz-300 GHz. The control method comprises the following steps: step S1, selecting the antenna with the current received signal intensity larger than the intensity threshold value from all opened antennas and taking the antenna as the selected target, and then closing the unselected antenna; in step S2, antennas with approximately the same received signal strength are selected from all the selected objects and used together as the final object for data transmission, and then the unselected objects are turned off. The fact that the current received signal strengths are approximately consistent means that the absolute value of the difference between the current received signal strengths of the antennas is not greater than the difference threshold. In this embodiment, the intensity threshold is equal to the sum of the digital signal threshold of the antenna and the compensation value, wherein the compensation value has a value in the range of 15-25dbm, preferably 20 dbm. In this embodiment, the difference threshold may be selected to be 3-6 db. The digital signal threshold value is typically an inherent parameter given by the manufacturer before the antenna leaves the factory.
Therefore, the control method can select the antenna with the current received signal strength greater than the strength threshold value from all opened antennas to be used as the selected target, and then close the unselected antennas. The inventor finds out after great efforts that, because the electromagnetic wave in the millimeter wave band has strong straight-line propagation and extremely weak diffraction capability, a plurality of antennas are usually used to form a MIMO (large-scale antenna array) mode in the mobile terminal to improve the communicable range, but when an obstacle blocks the antenna, the signal strength received by the antenna is significantly deteriorated, so that the antenna cannot be used for transmitting data and continuously consumes energy, and therefore, the antenna not greater than the intensity threshold is turned off, so that the energy consumption of the antenna of the mobile terminal can be effectively reduced. The control method can also select antennas with approximately consistent current received signal strength from all the selected targets, and the antennas are used as final targets for transmitting data together, and then the unselected targets are closed. Because the MIMO (large-scale antenna array) mode mainly gains the transmission data of the antennas through space diversity, and the premise of realizing the space diversity gain is that the signal strengths are approximately consistent, that is, when the absolute value of the difference between the signal strengths received by the two antennas is greater than the difference threshold, the space diversity gain cannot be realized between the two antennas, and when the signal strengths received by the antennas are approximately consistent, a space diversity gain effect can be generated between the antennas, so as to improve the data throughput and the mobile communication quality of the mobile terminal, so that the energy consumption of the mobile terminal can be further reduced by turning off the unselected antennas after selecting the antennas whose current received signal strengths are approximately consistent. Therefore, the control method can solve the problem of high energy consumption of the mobile terminal, can meet the requirement of the mobile terminal on data throughput, ensures the mobile communication quality of the mobile terminal, and reduces the energy consumption of the mobile terminal during the use of mobile communication.
In this embodiment, step S2 further includes: when there is no antenna with approximately consistent current received signal strength in all the selected targets, one antenna with the highest current received signal strength is selected from all the selected targets as a final target for transmitting data, and then the unselected selected targets are closed. In this way, it is possible to avoid a scenario in which the mobile terminal does not have an antenna available when spatial diversity gain cannot be achieved.
In other embodiments, step S2 specifically includes: step S201, sequencing all selected targets according to the intensity of the current received signal, and assigning a value 1 to a variable i; step S202, an ith selected target is extracted from all selected targets to serve as a comparison target, and then whether a selected target with a current received signal not less than a first set value and not more than a second set value exists in all selected targets with serial numbers more than i is judged, wherein the first set value is equal to the current received signal strength of the comparison target, and the second set value is equal to the sum of the current received signal strength of the comparison target and a difference threshold; step S203, if the judgment result in the step S202 is yes, the selected target and the comparison target of which the current received signal strength is not less than the first set value and not more than the second set value are selected as the antennas of which the current received signal strengths are approximately consistent, and are jointly used as the final target for transmitting data, and then the unselected selected target is closed; step S204, if the judgment result of the step S202 is negative, judging whether i is equal to the total number of the selected targets; step S205, if the judgment result in the step S204 is negative, the number of the results of i +1 is given to i, and the step S202 is returned; step S206, if the result of the determination in step S204 is yes, selecting one antenna with the highest current received signal strength from all the selected targets as the final target for data transmission, and then closing the unselected selected targets. In this way, step S2 can be implemented efficiently and safely, but the implementation of step S2 is not limited thereto.
In an embodiment, not shown, there is also provided a mobile terminal comprising a memory for storing computer program instructions and a processor for executing the computer program instructions, wherein the processor is configured to implement the control method described above when executing the computer program instructions.
In an embodiment not shown, there is also provided a computer readable medium having stored thereon computer program instructions executable by a processor to implement the control method described above.
In summary, the control method of the mobile terminal antenna, the mobile terminal and the computer readable medium provided by the present invention can solve the problem of high energy consumption of the mobile terminal, and can reduce the energy consumption of the mobile terminal when using mobile communication while meeting the requirement of the mobile terminal on data throughput and ensuring the mobile communication quality of the mobile terminal.
