Description
Technical Field
The present application relates to the field of communications, and in particular, to a communication apparatus, a control method, a control apparatus, a mobile terminal, and a storage medium.
Background
The frequency band range adopted by 5G communication systems such as Non-Stand Alone Networks (NSA) and Stand Alone networks (SA) comprises a low frequency band range and a high frequency band range, wherein the low frequency band range is 450-6000 MHz, and the high frequency band range is 24.25-52.6 GHz.
Since the lower frequencies are bands of longer wavelengths, the longer distances that can be propagated, e.g., in the less popular regions of north america, the lower frequency band is the more commonly used band. However, the communication rate of the low frequency band is low, and therefore, in order to ensure the communication quality, the mobile terminal may adopt a dual low frequency band combination communication mode. Currently, dual low frequency is mainly endec (LTE and NR working simultaneously, e.g. B20+ N28) mode.
Generally, in order to realize B20+ N28 dual low frequency communication, more than two antennas are required to satisfy 2T4R (T is a transmission path and R is a reception path).
In the related art, for example, a mobile terminal such as a mobile phone and the like to implement dual low frequency communication in the frequency division duplex mode, two antennas of 2T2R (supporting dual frequency communication) or four antennas of 1T2R (supporting single frequency communication) may be used. Wherein, two 2T2R (supporting dual-frequency communication) antennas are respectively arranged at the bottom edge, the side edge or the bottom edge and the top edge of the mobile terminal. Four 1T2R (supporting single frequency communication) antennas are adopted and respectively arranged on four sides of the mobile terminal. However, on the one hand, the antenna of 2T2R occupies a space and generates electromagnetic radiation larger than the antenna of 1T2R, and on the other hand, the mobile terminal has a limited accommodation space, and the accommodation space on the side is smaller than that on the bottom or upper side. If two 2T2R antennas are used and are respectively disposed on the bottom side and the side edge of the mobile terminal, the antenna 2T2R (supporting dual-frequency communication) occupies a large space, the space on the side edge is small, the design difficulty is increased, and the cost is increased. If the mobile terminal employs two antennas 2T2R and is located on the bottom and top sides, respectively, the top antenna generates electromagnetic radiation exceeding a specified value because the top antenna is closer to the user when the user is using the mobile terminal. If four 1T2R antennas are used and are respectively arranged on four sides, the circuit design is complex and the occupied space is too large.

The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.
Frequency band ranges adopted by fifth generation mobile communication (5G) systems such as Non-Stand Alone Networks (NSA) and Stand Alone networks (SA) include a low frequency band range and a high frequency band range, wherein the low frequency band range is 450-6000 MHz, and the high frequency band range is 24.25-52.6 GHz.
Currently, a 5G communication system of a mobile terminal can implement communication by using a dual low-frequency band combined communication mode of low frequency plus low frequency. Wherein the dual low band ranges between 600 and 1000 MHz. It can be understood that the propagation distance of the electromagnetic wave in the space is inversely related to the frequency thereof, that is, the lower the frequency of the electromagnetic wave, the longer the distance is propagated in the space, and the propagation rate of the electromagnetic wave in the space is positively related to the frequency thereof, that is, the lower the frequency of the electromagnetic wave, the lower the propagation rate of the electromagnetic wave in the space is. Therefore, the communication quality can be ensured by a dual low-frequency combination communication method of low frequency plus low frequency. Currently, dual low frequency is mainly endec (LTE and NR work simultaneously, e.g. B20+ N28 mode), B20 is one frequency band supported by LTE, and N28 is one frequency band supported by NR. To realize the dual low frequency communication of B20+ N28, transmission (T) and reception (R) of B20 and N28 need to be performed simultaneously. In order to effectively improve the receiving capability of mobile terminals such as mobile phones, 2 antennas are generally required to operate and receive simultaneously (i.e. 2R) in each frequency band, so that 2T4R is required when B20+ N28 operates.
However, on the one hand, the lower the frequency, the longer the required length of the antenna, the wider the frequency band, and the longer the length required for the antenna, and in general, an antenna that is required to satisfy single low frequency band communication generally requires at least 55mm in length, and if an antenna is required to satisfy dual low frequency band communication, the length required is longer than that of an antenna for single low frequency communication, and the radiation generated by an antenna for dual low frequency communication is larger than that of an antenna for single low frequency band communication. On the other hand, because the antenna is generally disposed on the frame of the mobile terminal for better receiving and transmitting signals, the mobile terminal has a limited accommodating space due to the limitation of volume, and the accommodating space on the side is smaller than that on the bottom or upper side.
In the related art, the mobile terminal may use two antennas 2T2R (supporting dual-frequency communication) or four antennas 1T2R (supporting only single-frequency communication) to implement dual low-frequency communication in the endec mode. The two 2T2R antennas can be respectively disposed on the bottom side and the side of the mobile terminal, or on the bottom side and the top side, and four 1T1R (supporting single frequency communication) antennas are respectively disposed on the four sides of the mobile terminal. However, if two antennas 2T2R are adopted and respectively disposed on the bottom side and the side of the mobile terminal, the antenna 2T2R needs to support dual-band communication at the same time, so that the space requirement of the antenna 2T2R is increased (usually designed as a dual-branch), and the complexity and cost of devices such as a switch and the like associated with the antenna 2T2R are also increased. If the mobile terminal adopts two 2T2R antennas and is respectively arranged on the bottom side and the top side, because the 2T2R antenna generates a larger electromagnetic radiation value, and when the mobile terminal is used by a user, the 2T2R antenna arranged on the top side is closer to the user, the Absorption Rate (SAR) of the human body to electromagnetic waves exceeds a specified SAR value, and if the power is reduced and the SAR is satisfied, the over-the-air (OTA) is not easily satisfied. If four 1T1R antennas are used and disposed on four sides, the circuit design is complicated, which increases the cost and occupies too much space.
Referring to fig. 1, therefore, the present application provides a communication device 10 for a mobile terminal 100, where the mobile terminal 100 includes a main body 20, and the communication device 10 is mounted on the main body 20. The mobile terminal 100 implements dual low frequency communication through the communication device 10.
Specifically, the main body 20 includes a bottom wall 21, a first side wall 22, and a second side wall 23. The first side wall 22 and the first side wall 22 are oppositely disposed at two ends of the bottom wall 21, and two ends of the bottom wall 21 are respectively connected to the first side wall 22 and the second side wall 23. The communication device 10 includes a first antenna 11, a second antenna 12, and a third antenna 13. The first antenna 11 is disposed on the bottom wall 21, the second antenna 12 is disposed on the first sidewall 22, and the third antenna 13 is disposed on the second sidewall 23.
The mobile terminal 100 may be a mobile phone, a tablet computer, etc., in this application, the mobile terminal 100 is illustrated as a mobile phone, that is, the mobile terminal 100 is not limited to a mobile phone.
The communication device 10 may use non-independent networking or independent networking for communication, and the specific communication method is not limited.
Please refer to fig. 2, it should be noted that the dual low band refers to two different low bands within the low band range, and in the present application, the low band range is 600-1000 MHz. For example, the dual low band includes a low band f1 and a low band f 2. The frequency range of the low frequency band f1 is 650-750MHz, and the frequency range of the low frequency band f2 is 750-850 MHz. The first antenna 11 may support an antenna for receiving and transmitting two frequency band ranges (2T2R), and the second antenna 12 and the third antenna 13 support an antenna for receiving and transmitting only one frequency band range (1T 2R). The frequency band ranges supported by the first antenna 11, the second antenna 12 and the third antenna 13 are all within a low frequency band range, that is, the frequency band ranges supported by the first antenna, the second antenna and the third antenna are between 600 and 1000 MHz. For example, in the B20 and N28 modes, the first antenna 11 may support both signal reception and transmission of B20 and signal reception and transmission of N28, while the second antenna 12 and the third antenna 13 support only reception and transmission of B20 signals or only reception and transmission of signals in N28.
Further, the frequency band range supported by the second antenna 12 is different from the frequency band range supported by the third antenna 13, and the frequency band range supported by the first antenna 11 includes the frequency range supported by the second antenna 12 and the frequency range supported by the third antenna 13. For example, if the frequency bands supported by the first antenna 11 are f1 and f2, the frequency band supported by the second antenna 12 is f1 and the frequency band supported by the third antenna 13 is f2, or the frequency band supported by the second antenna 12 is f2 and the frequency band supported by the third antenna 13 is f 1.
The bottom wall 21, the first side wall 22, and the second side wall 23 are made of a metal material, and the specific material is not limited, and the material used for the first antenna 11, the second antenna 12, and the third antenna 13 is not limited, and may be, for example, a Polyimide (PI), a Liquid Crystal Polymer (LCP), a Modified Polyimide (MPI), or the like.
In summary, the communication device 10 can enable the mobile terminal 100 to implement dual low-frequency communication through the first antenna 11, the second antenna 12 and the third antenna 13, so as to meet the 5G communication requirements of independent networking or non-independent networking. Moreover, the first antenna 11 is disposed on the bottom wall 21, and the second antenna 12 and the third antenna 13 are disposed on the first side wall 22 and the second side wall 23 respectively, so that the electromagnetic radiation can reach the standard, better isolation between the antennas can be achieved, and meanwhile, the design difficulty is reduced and the cost is saved.
Referring to fig. 3, in some embodiments, the first sidewall 22 and the second sidewall 23 are trisected along the length direction into a bottom region C close to the bottom wall 21, a top region a far from the bottom wall 21, and a middle region B between the bottom region C and the top region, the second antenna 12 and the third antenna 13 are located in the middle region B and the top region a, more than half of the second antenna 12 is located in the top region a, and more than half of the third antenna 13 is located in the middle region B.
In some embodiments, the communication device 10 further includes a modem 14(modem), the modem 14 is connected to the first antenna 11, the second antenna 12, and the third antenna 13, respectively, and the modem 14 is configured to transmit the dual low frequency signals to the first antenna 11, the second antenna 12, and the third antenna 13.
It should be noted that the dual low frequency signal refers to two low frequency signals within two different low frequency band ranges, that is, two different low frequency signals within a frequency band range of 600-1000 MHz. In the present application, the two low frequency signals are distinguished by a first low frequency signal and a second low frequency signal. The first low-frequency signal or the second low-frequency signal can only be transmitted by a single antenna, that is, the first low-frequency signal and the second low-frequency signal are respectively transmitted by two antennas. The first antenna 11 can support both the first low frequency signal transmission and the second low frequency signal transmission, and the second antenna 12 and the third antenna 13 support only one corresponding low frequency signal transmission.
It should be noted that the frequency band ranges of the transmitted low-frequency signal and the received low-frequency signal in the same frequency band range are not necessarily the same. Referring to fig. 4, for example, in the low dual-band communication scheme of B20+ N28 adopted by the communication device 10, the frequency band range of N28 is f1, the frequency band range of B20 is f2, wherein the low-frequency signal range transmitted by N28 is Tx1 (first low-frequency signal), the low-frequency signal range received is Rx1, the low-frequency signal range transmitted by B20 is Tx2 (second low-frequency signal), and the low-frequency signal range received is Rx 2.
Specifically, the modem 14 is provided in the main body 20, and is connected to the first antenna 11, the second antenna 12, and the third antenna 13, respectively. The modem 14 may transmit the first and second low frequency signals to the first, second, or third antenna 11, 12, or 13, or receive the first and second low frequency signals from the first, second, or third antenna 11, 12, or 13. Further, the modem 14 generates a first low frequency signal and a second low frequency signal, which are respectively transmitted to any two antennas of the first antenna 11, the second antenna 12 and the third antenna 13 to transmit the first low frequency signal and the second low frequency signal.
Referring to fig. 3, in some embodiments, the first antenna 11 is disposed on a side of the bottom wall 21 close to the first sidewall 22, and the second antenna 12 is disposed on a side of the first sidewall 22 away from the bottom wall 21 and offset from the third antenna 13.
Specifically, the first antenna 11 includes a first radiator 111, a first feeding line 112, and a ground line 113. The first radiator 111 is disposed outside the bottom wall 21 and near one side of the first sidewall 22, and a portion of the first radiator 111 bends and extends toward the first sidewall 22, the first feeding line 112 is connected to the first radiator 111 and penetrates from the bottom wall 21 into the main body 20 to form a first branch and a second branch, the first branch is connected to ground, and the second branch is communicated with the modem 14. The first branch also comprises a first antenna switch SW1 for controlling signal receiving or sending. The ground line 113 is connected to the first radiator 111, penetrates the body 20 from the bottom wall 21, and is grounded, and the ground line 113 is further provided with a second antenna switch SW2 that controls signal reception or transmission.

The third branch is also provided with a third antenna switch SW3 that controls signal reception or transmission.
Further, the third antenna switch SW3 may also adjust the frequency band range supported by the second antenna 12, so that the second antenna 12 may support different frequency band ranges under different conditions, for example, the first low frequency signal is in the frequency band range of f1, the second low frequency signal is in the frequency band range of f2, and the frequency band range of the second antenna 12 is f1, in order to enable the second antenna 12 to transmit the second low frequency signal, the adjustment may be performed through the third antenna switch SW3, and the frequency band range supported by the second antenna 12 is adjusted from f1 to f 2.
The third antenna 13 includes a third radiator 131 and a third feed line 132. The third radiator 131 is disposed outside the second sidewall 23 and opposite to the second radiator 121 in a staggered manner, and it can be understood that the isolation between the second radiator 121 and the third radiator 131 can be further improved by disposing the second radiator 121 and the third radiator 131 in a staggered manner. The third feeding line 132 is connected to the third radiator 131 and penetrates into the main body 20 from the second sidewall 23, and is formed with a fifth branch connected to the ground and a sixth branch communicated with the modem 14. The fourth branch is also provided with a fourth antenna switch SW4 that controls signal reception or transmission.
Further, the fourth antenna switch SW4 may also adjust the frequency band range supported by the third antenna 13, so that the third antenna 13 may support different frequency band ranges under different conditions, for example, the first low frequency signal is in the frequency band range of f1, the second low frequency signal is in the frequency band range of f2, and the frequency band range of the third antenna 13 is f1, and in order to enable the third antenna 13 to transmit the second low frequency signal, the frequency band range supported by the third antenna 13 may be adjusted from f1 to f2 by the fourth antenna switch SW 4.
Referring to fig. 3, it can be understood that, since the antenna generates electromagnetic radiation through the radiators, if the mobile terminal 100 is divided into A, B and C regions, and the first radiator 111, the second radiator 121 and the third radiator 131 are arranged, the electromagnetic radiation generated by the first radiator 111 is mainly in the region C, the electromagnetic radiation generated by the second radiator 121 is mainly in the region a, and the electromagnetic radiation generated by the third radiator 131 is mainly in the region B, so that interference between electromagnetic wave pairs generated by the respective antennas is reduced.
In some embodiments, the communication device 10 includes a signal control switch 15. The first antenna 11, the second antenna 12 and the third antenna 13 are connected to the modem 14 through a signal control switch 15, and the signal control switch 15 is used for distributing dual low frequency signals to two of the first antenna 11, the second antenna 12 and the third antenna 13.
Specifically, the signal control switch 15 is disposed in the main body 20, and the modem 14 is connected to the first feeding line 112, the second feeding line 122 and the third feeding line 132 through the signal control switch 15. When the modem 14 generates the first low frequency signal and the second low frequency signal and transmits the first low frequency signal and the second low frequency signal to the signal control switch 15, the signal control switch 15 may distribute the first low frequency signal and the second low frequency signal and transmit the first low frequency signal and the second low frequency signal to two feeding lines of the first feeding line 112, the second feeding line 122, and the third feeding line 132, respectively, so that two antennas of the first antenna 11, the second antenna 12, and the third antenna 13 may transmit the first low frequency signal and the second low frequency signal, respectively. In this manner, by setting the signal control switch 15, the antenna for transmitting the first low-frequency signal and the antenna for transmitting the second low-frequency signal can be switched arbitrarily.
Referring to fig. 5, for example, after the modem 14 generates the first low frequency signal and the second low frequency signal, in some examples, the signal control switch 15 may send the first low frequency signal to the first feeding line 112, transmit the first low frequency signal through the first antenna 11, send the second low frequency signal to the second feeding line 122, and transmit the second low frequency signal through the second antenna 12. In other examples, the signal control switch 15 may transmit the first low frequency signal to the second feeding line 122, transmit the first low frequency signal through the second antenna 12, transmit the second low frequency signal to the third feeding line 132, and transmit the second low frequency signal through the third antenna 13.
In this way, the setting of the signal control switch 15 allows the communication device 10 to arbitrarily select two antennas among the first antenna 11, the second antenna 12, and the first antenna 11 to transmit the first low-frequency signal and the second low-frequency signal. The anti-interference capability of the communication device 10 is enhanced, and the user experience is improved.
Referring to fig. 6 and 7, in some embodiments, the signal control switch 15 includes a first signal control sub-switch 151 and a second signal control sub-switch 152, the first antenna 11 is connected to the modem 14 through the first signal control sub-switch 151, the second antenna 12 and the third antenna 13 are connected to the first signal control sub-switch 151 through the second signal control sub-switch 152, the first signal control sub-switch 151 is configured to distribute the first low frequency signal and the second low frequency signal transmitted by the modem 14 to the first antenna 11 and the second signal control sub-switch 152, and the second signal control sub-switch 152 is configured to transmit the first low frequency signal or the second low frequency signal distributed by the first signal control sub-switch 151 to the second antenna 12 or the third antenna 13.
Specifically, when the communication apparatus 10 communicates, the modem 14 generates a first low-frequency signal and a second low-frequency signal and transmits the first low-frequency signal and the second low-frequency signal to the first sub-signal control switch 15, and the first signal control sub-switch 151 distributes the first low-frequency signal and the second low-frequency signal so as to transmit the first low-frequency signal to the first antenna 11 and transmit the second low-frequency signal to the second signal control sub-switch 152, or transmit the second low-frequency signal to the first antenna 11 and transmit the first low-frequency signal to the second signal control sub-switch 152. The second signal control sub-switch 152 receives the first low-frequency signal or the second low-frequency signal and then transmits the first low-frequency signal or the second low-frequency signal to the second antenna 12, or the second signal control sub-switch 152 receives the first low-frequency signal or the second low-frequency signal and then transmits the first low-frequency signal or the second low-frequency signal to the third antenna 13. Further, the first signal control sub-switch 151 may be a double pole double throw switch (2P2T), and the second signal control sub-switch 152 may be a single pole double throw switch (SP 2T). In the present application, the signal control switch 15 is only allocated to the transmission of the first low-frequency signal and the second low-frequency signal.
In this manner, the first signal control sub-switch 151 and the second signal control sub-switch 152 are set so that the communication apparatus 10 can transmit the first low frequency signal and the second low frequency signal by the first antenna 11 and the second antenna 12, or by the first antenna 11 and the third antenna 13. Furthermore, since the radiation efficiency of a single antenna supporting one frequency band is greater than that of a single antenna supporting two frequency bands, the present embodiment improves the radiation efficiency of the communication device 10 compared to the case where two antennas supporting two frequency bands are used.

Referring to fig. 12, the present application provides one or more non-transitory computer-readable storage media 50 containing computer-executable instructions that, when executed by one or more processors 30, cause the processors 30 to perform a control method.
In the communication device 10, the control method, the control device 200, the mobile terminal 100, and the computer-readable storage medium 40 of these embodiments, it is determined whether the communication of the second antenna 12 is blocked by determining whether the communication signal strength of the second antenna 12 is greater than that of the third antenna 13, and if the communication of the second antenna 12 is blocked, the dual low frequency signals can be transmitted by the first antenna 11 and the third antenna 13, and if the communication of the second antenna 12 is not blocked, the dual low frequency signals can be transmitted by the first antenna 11 and the second antenna 12, so that the interference rejection capability of the communication device 10 is improved.
The control device 200 may be hardware or software preinstalled on the mobile terminal 100 and may perform a control method when it is booted on the mobile terminal 100. For example, the control device 200 may be an underlying software code segment or part of an operating system on the mobile terminal 10. As such, when the communication apparatus 100 generates a dual low frequency signal, it is possible to control the first antenna 11 and the second antenna 12 or control the first antenna 11 and the third antenna 13 to transmit the dual low frequency signal.
In some embodiments, the control device 200 may be part of the mobile terminal 100. In other words, the mobile terminal 100 includes the control device 200.
In some embodiments, the control device 200 may be a discrete component assembled in such a way as to have the aforementioned functions, or a chip having the aforementioned functions in the form of an integrated circuit, or a piece of computer software code that causes a computer to have the aforementioned functions when run on the computer.
In some embodiments, the control device 200 may be a stand-alone or add-on peripheral component to a computer or computer system as hardware. The control device 200 may also be integrated into a computer or computer system, for example, the control device 200 may be integrated into the processor 30 when the control device 200 is part of the mobile terminal 100.
In some embodiments, the control device 200 is a part of the mobile terminal 100, and as software, a code segment corresponding to the control device 200 may be stored on the memory 30 and executed on the processor 30 to implement the aforementioned functions. Or the control device 200 includes one or more programs described above, or the one or more programs described above include the control device 200.
In some embodiments, the computer-readable storage medium 50 may be a storage medium built in the mobile terminal 100, such as the memory 40, or a storage medium that can be plugged into the mobile terminal 100 in a pluggable manner, such as an SD card.
It can be understood that, since the second antenna 12 and the third antenna 13 are respectively disposed on the first side wall 21 and the second side wall 22, when a user interacts with the mobile terminal 100, the user usually holds the first side wall 21 or the second side wall 22 of the mobile terminal 100 with hands in half, which is likely to cause interference to the second antenna 12 or the third antenna 13, and affect communication of the second antenna 12 or the third antenna 13. Accordingly, the processor 30 may compare the communication signal strengths of the second antenna 12 and the third antenna 13 after the modem 14 generates the dual low frequency signal, and thus may determine whether the dual low frequency signal is transmitted by the first antenna 11 and the second antenna 12 or the dual low frequency signal is transmitted by the first antenna 11 and the third antenna 13.
Specifically, after the processor 30 controls the modem 14 to generate the dual low frequency signal, that is, after the first low frequency signal and the second low frequency signal are generated, the communication signal strength of the second antenna 12 and the communication signal strength of the third antenna 13 are obtained, and it is determined whether the communication signal strength of the second antenna 12 is greater than the communication signal strength of the third antenna 13. If the processor 30 determines that the communication signal strength of the second antenna 12 is greater than the communication signal strength of the third antenna 13, it may determine that the communication of the third antenna 13 is interfered, and may control the second antenna 12 to transmit the first low frequency signal and control the first antenna 11 to transmit the second low frequency signal, or may control the second antenna 12 to transmit the second low frequency signal and control the first antenna 11 to transmit the first low frequency signal.
Further, in some embodiments, please refer to fig. 6 and 7, the processor 30 may control the second signal control sub-switch 152 and the first signal control sub-switch 151 to enable the second antenna 12 and the first antenna 11 to transmit the first low frequency signal and the second low frequency signal so as to implement the dual low frequency communication of the mobile terminal 100, or control the second signal control sub-switch 152 and the first signal control sub-switch 151 to enable the third antenna 12 and the first antenna 11 to transmit the first low frequency signal and the second low frequency signal so as to implement the dual low frequency communication.
In this way, the first signal control sub-switch 151 and the second signal control sub-switch 152 are arranged, so that the communication device 10 can transmit the first low-frequency signal and the second low-frequency signal through the first antenna 11 and the second antenna 12, or through the first antenna 11 and the third antenna 13, thereby effectively avoiding the situation that the signal strength is greatly changed due to the fact that the user is held when holding the mobile terminal 100.
Please refer to fig. 13, the present application further provides a control method, where the control method includes the steps of:
s12: controlling the modem to generate a dual low frequency signal;
s20: judging whether the communication signal intensity of the first antenna is smaller than a preset value;
s22: and when the communication signal strength of the first antenna is smaller than a preset value, controlling the second antenna 12 and the third antenna 13 to transmit double low-frequency signals.
Referring further to fig. 9, in some embodiments, the control apparatus 100 further includes a second determining module 20 and a second control module 22. The step S20 may be implemented by the second determination module 20, and the step S22 may be implemented by the fourth control module 22.
Or, the second determining module 20 is configured to determine whether the communication signal strength of the first antenna 11 is smaller than a preset value.
The second control module 22 is configured to control the second antenna 12 and the third antenna 13 to transmit the dual low-frequency signal when the communication signal strength of the first antenna 11 is smaller than a preset value.
In some embodiments, the processor 30 is configured to determine whether the communication signal strength of the first antenna 11 is smaller than a preset value. The processor 30 is further configured to control the second antenna 12 and the third antenna 13 to transmit the dual low-frequency signal when the communication signal strength of the first antenna 11 is smaller than a preset value.
The preset value refers to a preset value, and the preset value may be set by a factory or a user. The preset value may be stored in the computer-readable storage medium 40, and called by the processor 30 or the control device 200.
It will be appreciated that in some examples, the first antenna 11 disposed on the bottom wall 21 may also be blocked from communicating, for example, when a user plays a game or watches a movie using the mobile terminal 100, the bottom wall 21 and a top wall on the side opposite to the bottom wall 21 are held by both hands, thereby causing the first antenna 11 disposed on the bottom wall 21 to be blocked from communicating. Therefore, after controlling the modem 14 to generate the first low frequency signal and the second low frequency signal, the processor 30 may further determine whether the communication signal strength of the first antenna 11 is smaller than a preset value, and if the communication signal strength of the first antenna 11 is smaller than the preset value, it may be determined that the communication of the first antenna 11 is blocked, and the processor 30 may control the second antenna 12 and the third antenna 13 to transmit the first low frequency signal and the second low frequency signal, so as to implement the dual low frequency communication of the mobile terminal 100.
The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
