Detailed Description

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

Fig. 1 is a flowchart of steps of a communication control method provided in an embodiment of the present invention, where the method may be applied to a terminal, and the terminal may include a data communication antenna, a wireless communication switch, and a received signal amplifier, where the wireless communication antenna and the received signal amplifier are connected through the wireless communication switch, and as shown in fig. 1, the method may include:

step 101, obtaining the transmitting power of the data communication antenna.

In the embodiment of the present invention, the data communication antenna may be configured to receive and transmit a data communication signal, where the data communication signal may be a cellular mobile data signal, and the Wireless communication antenna may be configured to receive and transmit a Wireless communication signal (WiFi), and since the frequency of the data communication signal may be very close to the frequency of the Wireless communication signal, for example, when the data communication antenna transmits the N97 signal, the highest frequency of the data communication signal may reach 5, and the frequency of the Wireless communication signal may be 5.18, the data communication signal transmitted by the data communication antenna may be received by the Wireless communication antenna, and further, since the transmission power of the data communication signal may be relatively large, and further, the Wireless communication device, that is, the receiving signal amplifier may be damaged, in this step, the transmission power may be obtained.

Step 102, adjusting the working mode of the wireless communication switch and/or the receiving signal amplifier according to the transmitting power, the first isolation and the first tolerance value.

In this embodiment of the present invention, the first isolation may be an isolation between the wireless communication antenna and the data communication antenna, and the first tolerance value may be a maximum power tolerance value of the receiving signal amplifier.

In the embodiment of the present invention, in practical application, a certain distance often exists between the data communication antenna and the wireless communication antenna, and a certain attenuation is caused to the data communication signal, so that the received signal amplifier generally receives a part of the data communication signal, and accordingly, the power value applied to the received signal amplifier is often smaller than the transmission power of the data communication signal.

Further, since the wireless communication switch connects the wireless communication antenna and the receiving signal amplifier, the connection state between the wireless communication antenna and the receiving signal amplifier can be changed by adjusting the wireless communication switch, and thus the power applied to the receiving signal amplifier by the signal received by the wireless communication antenna can be changed, further, the receiving signal amplifier is used for power amplifying the signal, the operation mode of the receiving signal amplifier can be the increasing level of the receiving signal amplifier, the receiving signal amplifier is in different increasing levels, i.e. the signal is amplified to different degrees in different operation modes, and the terminal will also include other wireless receiving devices connected with the receiving signal amplifier, therefore, the power applied to other wireless receiving devices can be changed by adjusting the operation mode of the receiving signal amplifier, thereby preventing the wireless receiving device from being damaged.

Specifically, the terminal may determine, based on the transmission power and a first isolation between the wireless communication antenna and the data communication antenna, a power value applied to the received signal amplifier after the data communication signal is attenuated by the wireless communication antenna, that is, after the first isolation loss, then determine, based on the power value and the first tolerance value, whether the received signal amplifier is damaged, and control, based on a determination result, an operation mode of the wireless communication switch and/or the received signal amplifier to ensure that the wireless communication device is not damaged.

In summary, in the communication control method provided in the embodiment of the present invention, the terminal may obtain the transmission power of the data communication antenna, and then adjust the operating mode of the wireless communication switch and/or the received signal amplifier according to the transmission power, the first isolation and the first tolerance value, because the actual power value borne by the received signal amplifier can be determined according to the transmission power and the first isolation, the first tolerance value may represent the maximum power value that the received signal amplifier can bear, and the power borne by the received signal amplifier can be changed by adjusting the operating mode of the wireless communication switch and/or the received signal amplifier, in the embodiment of the present invention, the operating mode of the wireless communication switch and/or the received signal amplifier is adjusted according to the transmission power, the first isolation and the first tolerance value, so that the problem that the wireless communication device of the terminal is damaged can be avoided to a certain extent, thereby avoiding degrading the wireless communication performance of the terminal.

Fig. 2 is a flowchart of steps of another communication control method provided in an embodiment of the present invention, where the method may be applied to a terminal, and the terminal may include a data communication antenna, a wireless communication switch, and a received signal amplifier, where the wireless communication antenna and the received signal amplifier are connected through the wireless communication switch, and as shown in fig. 2, the method may include:

step 201, obtaining the transmitting power of the data communication antenna.

Specifically, the terminal may further include a data communication module, the data communication module may be connected to the data communication antenna, the data communication module may include a signal transceiver and a signal power amplifier, the signal transceiver may be configured to receive a data communication signal and transmit the data communication signal, and the signal power amplifier may be configured to amplify power of the data communication signal. In practical application scenarios, the terminal often uses the data communication module to transmit data communication signals through the data communication antenna, and further, the data communication module often establishes communication connection with the base station by transmitting data communication signals, when the connection is established, the base station to be communicated determines the minimum power value required for establishing the connection according to the actual distance and the current communication quality, then, the lowest power value is sent to the terminal, and accordingly, the terminal may further include a Central Processing Unit (CPU), and the terminal may control the data communication module to transmit the data communication signal with the power not lower than the lowest power value through the internal CPU to implement connection, generally, in order to save the transmission cost, the terminal controls the data communication module to transmit the data communication signal with the power equal to the minimum power value, therefore, in the embodiment of the present invention, the terminal may directly determine the minimum power value as the transmission power of the data communication signal.

Further, in an actual application scenario, under the influence of factors such as an external temperature, a working time of the signal transceiver, and a working accuracy, an actual transmission power of the data communication signal transmitted by the signal transceiver may deviate from the minimum power value, and therefore, the terminal may receive the sampling signal and determine the transmission power of the data communication signal based on the sampling signal, where the sampling signal is obtained by the signal power amplifier and forwarded to the CPU by the signal transceiver. Specifically, the specific process of determining the transmission power of the data communication signal based on the sampling signal may be as follows, sub-step (1) to sub-step (3): substep (1): and the terminal acquires a sampling signal through the signal power amplifier and sends the sampling signal to the signal transceiver.

In this step, the signal power amplifier may amplify an initial signal transmitted by the signal transceiver, and then transmit the amplified signal as a data communication signal by using a connected data communication antenna, and accordingly, the signal power amplifier may obtain a part of the signal from the amplified signal at a preset sampling rate as the sampling signal, and then transmit the sampling signal to the signal transceiver.

Substep (2): and the terminal sends the sampling signal to a CPU of the terminal through the signal transceiver.

In this step, the signal transceiver may send the sampled signal to the CPU to determine the actual power of the transmitted data communication signal by the CPU.

Substep (3): and the terminal receives the sampling signal through the CPU and determines the transmitting power of the data communication signal based on the sampling signal.

In this step, the CPU may receive the sampling signal, and then search for the transmission power corresponding to the power of the sampling signal from a preset corresponding relationship between the power of the sampling signal and the transmission power, to obtain the transmission power of the data communication signal. The preset correspondence between the power of the sampling signal and the transmission power may be generated at a debugging stage of the terminal, for example, the correspondence may be pre-recorded, when the data communication module transmits signals with different powers, the power of the sampling signal obtained from different signals at a preset sampling rate, and then the correspondence is established in a one-to-one correspondence form, further, the correspondence may be pre-written into the CPU at the debugging stage of the terminal, or pre-stored into a preset storage device, and the CPU reads from the storage device. In the embodiment of the invention, the sampling signal is obtained, and the transmitting power of the transmitted data communication signal is determined by the sampling signal, so that the transmitting power is more accurate, and further, the control operation is more accurate under the condition that the wireless communication switch is controlled by taking the transmitting power as a basis in the subsequent steps.

Further, in order to ensure that the wireless communication switch can be controlled in time to avoid the wireless communication receiving module from being damaged before the wireless communication device is not damaged, in the embodiment of the present invention, the terminal may further set the increase level of the receiving signal amplifier to the preset increase level before the terminal acquires the transmission power, that is, before step 201, and control the wireless communication switch to disconnect the receiving signal amplifier from the wireless communication antenna. The preset increasing level can be a level with the minimum signal increasing degree, and further, after the wireless communication switch disconnects the connection between the receiving signal amplifier and the wireless communication antenna, a certain isolation effect can be generated on the data communication signal, so that the wireless communication device can be ensured to be in a safe state without being damaged, the possibility that the wireless communication device is damaged is reduced, meanwhile, the increasing processing on the wireless communication signal is reserved, and further, the communication effect of the wireless communication is ensured.

Step 202, a first power value on the received signal amplifier is determined based on the transmit power and the first isolation.

In this step, the specific magnitude of the first isolation is related to specific parameters of the data communication antenna and the wireless communication antenna, and corresponds to different data communication antennas and wireless communication antennas, the magnitude of the first isolation may be different, the first isolation may represent the isolation degree of the signal, the greater the first isolation is, the greater the isolation degree of the data communication signal is, the smaller the first isolation is, the smaller the isolation degree of the data communication signal is, and the first isolation may be a ratio of power of the signal received by the wireless communication antenna to the power of the data communication signal, where the data communication signal is transmitted by the data communication antenna. Specifically, when the first power value is determined, the first isolation may be converted to be expressed in db, where db is 10logX, and accordingly, the transmission power may be converted to be dbm, that is, 10lg (power/1 milliwatt ratio), so that the first power value on the receiving signal amplifier may be obtained by directly calculating the difference between the transmission power and the first isolation. For example, assuming that the transmission power is X and the first isolation is Y, the first power value may be expressed as: X-Y.

Step 203, if the first power value is not less than the first tolerance value, controlling the wireless communication switch to disconnect the connection between the received signal amplifier and the wireless communication antenna.

For example, assuming that the first tolerance value is M, the terminal may control the wireless communication switch to disconnect the receiving signal amplifier from the wireless communication antenna when X-Y < M. Since the first tolerance value is the maximum power tolerance value of the received signal amplifier, if the first power value is not less than the first tolerance value, it can be considered that the first power value on the received signal amplifier may cause damage to the received signal amplifier, and therefore the terminal can control the wireless communication switch to disconnect the received signal amplifier from the wireless communication antenna,

furthermore, after the wireless communication switch is turned off, the data communication signal is further isolated, so that the received data communication signal is less, the power value of the receiving signal amplifier is smaller, the isolation degree after the wireless communication switch is turned off is often larger, and after the data communication module transmits the data communication signal, the data communication signal is received by the wireless communication antenna for a certain time, and the receiving signal amplifier has a certain tolerance time under the condition that the receiving signal amplifier receives a signal higher than the maximum power tolerance value of the receiving signal amplifier, that is, the receiving signal amplifier is not damaged within the tolerance time, therefore, in the step, the wireless communication switch is controlled to turn off the connection between the receiving signal amplifier and the wireless communication antenna under the condition that the first power value is not less than the first tolerance value, so that the problem that the receiving signal amplifier is damaged can be avoided to a certain extent, thereby ensuring that wireless communication performance is not affected.

In summary, in the communication control method provided in the embodiment of the present invention, the terminal may obtain the transmission power of the data communication antenna, and then determine the first power value on the received signal amplifier based on the transmission power and the first isolation, and if the first power value is not less than the first tolerance value, it indicates that the currently transmitted data communication signal may damage the received signal amplifier, so that the terminal may control the wireless communication switch to disconnect the received signal amplifier from the wireless communication antenna, so as to reduce the power value on the received signal amplifier, thereby avoiding the problem that the received signal amplifier is damaged to a certain extent, and further determining that the wireless communication performance of the terminal is not affected.

Fig. 3-1 is a flowchart of steps of another communication control method provided in an embodiment of the present invention, where the method may be applied to a terminal, and the terminal may include: a data communication antenna, a wireless communication switch, a received signal amplifier, and a wireless module integrated circuit IC, the wireless module IC being connected to the wireless communication antenna through the received signal amplifier, the wireless communication antenna being connected to the received signal amplifier through the wireless communication switch, and further, as shown in fig. 3-1, the method may include:

step 301, obtaining the transmitting power of the data communication antenna.

Specifically, the implementation manner of this step may refer to step 201 described above, and details of the embodiment of the present invention are not described herein.

Step 302, determining a first power value on the received signal amplifier based on the transmit power and the first isolation.

Specifically, the implementation manner of this step may refer to step 203 described above, and details of the embodiment of the present invention are not described herein.

Step 303, if the first power value is smaller than the first tolerance value, determining a corresponding second power value on the radio module IC in each increase level based on a power increment of at least one increase level of the received signal amplifier, the transmission power and the first isolation.

In this step, if the first power value is smaller than the first tolerance value, it may be considered that the data communication signal is applied to the received signal amplifier, and the received signal amplifier is not damaged, and further, in order to avoid the data communication signal from damaging the wireless module IC, in this embodiment of the present invention, the corresponding second power value on the wireless module IC may be further calculated. In general, the received signal amplifier may support a plurality of increasing levels, a power increment of an increasing level indicates an increasing amount when the received signal amplifier increases the signal power based on the increasing level, and the power increment is different for each increasing level, wherein the higher the increasing level is, the larger the power increment is. Specifically, since the data communication signal is attenuated by the antenna when being transmitted to the wireless module IC and then amplified by the received signal amplifier, when the second power value is determined, the difference between the transmission power and the first isolation may be calculated first, and then the sum of the difference and the power increment of the increased level may be calculated, so as to obtain the corresponding second power value on the wireless module IC of the increased level.

By way of example, assume that the receive signal amplifier includes two stages of amplification: a first boost level indicating a low gain mode and a second boost level indicating a high gain mode, the power increment of the second boost level being G1db, the power increment of the first boost level being G2db, G1 > G2, then the second power value at the first boost level may be: X-Y + G2, the second power value at the second increased level may be: X-Y + G1, and two second power values are obtained.

Step 304, adjusting an operation mode of the wireless communication switch and/or the received signal amplifier based on a second tolerance value and at least one of the second power values.

In this step, the increase level of the received signal amplifier may be set based on a second power value corresponding to the radio module IC in each increase level, that is, a power value to which the radio module IC is subjected in different increase levels, when the first power value is smaller than the first tolerance value, so as to control the wireless communication switch to control the power value on the radio module IC to be smaller than the second tolerance value, thereby ensuring that the radio module IC is not damaged, where the second tolerance value is a maximum power tolerance value of the radio module IC.

Specifically, the step can be realized by the following steps 3041 and 3042 or 3043 and 3044:

step 3041, if there is a target second power value smaller than the second tolerance value in at least one of the second power values, taking a maximum value of the target second power values as a target power value.

In this step, each second power value may be compared with the second tolerance value to determine a target second power value smaller than the second tolerance value, and then, a maximum power value is selected from the target second power values as the target power value. For example, assuming that the second tolerance value is Ndbm, the second power value: X-Y + G1 is less than N, X-Y + G2 is less than N, there are two target second power values that are less than this second tolerance value, and X-Y + G1 can be taken as the target power value because X-Y + G1 is greater than X-Y + G2. For another example, assume that the second power value: X-Y + G1 is not less than N, X-Y + G2 is less than N, there is a target second power value less than the second tolerance value, and therefore, X-Y + G2 can be taken as the target power value.

Step 3042 of setting the increase level of the received signal amplifier to the increase level corresponding to the target power value, and controlling the wireless communication switch to connect the received signal amplifier and the wireless communication antenna.

For example, assuming that X-Y + G2 is the target power value, the increase level of the received signal amplifier may be set to the first increase level corresponding to X-Y + G2, and the wireless communication switch may be controlled to connect the received signal amplifier to the wireless communication antenna. That is, in the case where X-Y < M and X-Y + G2 < N ≦ X-Y + G1, the wireless module IC is prevented from being damaged while the wireless communication quality is ensured as much as possible by setting the reception signal amplifier to the low gain mode and controlling the wireless communication switch to connect the reception signal amplifier and the wireless communication antenna. Further, assuming that X-Y + G1 is the target power value, the increase level of the received signal amplifier may be set to a second increase level corresponding to X-Y + G1, and the wireless communication switch may be controlled to connect the received signal amplifier to the wireless communication antenna. That is, in the case where X-Y < M and X-Y + G1 < N, the reception signal amplifier is set to the high gain mode, and the wireless communication switch is controlled to connect the reception signal amplifier and the wireless communication antenna, thereby preventing the wireless module IC from being damaged while ensuring the wireless communication quality as much as possible.

In the embodiment of the invention, the increase grade corresponding to the maximum value in the target second power value smaller than the second tolerance value is set as the increase grade of the receiving signal amplifier, and the receiving signal amplifier is controlled to be connected with the wireless communication antenna, so that the wireless module IC is ensured not to be damaged, and simultaneously, higher power gain is set for the receiving signal amplifier as much as possible, and further, the quality of wireless communication is ensured.

Step 3043, if there is no target second power value smaller than the second tolerance value in the at least one second power value, determining a third power value corresponding to the wireless module IC in the at least one increased class based on the second power value corresponding to each increased class and the disconnection isolation of the wireless communication switch.

In this step, the disconnection isolation degree of the wireless communication switch indicates an isolation degree that would be generated when the wireless communication switch disconnects the connection between the received signal amplification and the wireless module IC. Further, if there is no target second power value smaller than the second tolerance value among the at least one second power value, it can be considered that a problem that the radio module IC is damaged may occur even if the power increase of the received signal amplifier is controlled to reach the minimum increase, and therefore, in this step, the third power value can be determined. Specifically, the sum of the second power value corresponding to the increased level and the disconnection isolation may be calculated, that is, the third power value corresponding to the wireless module IC in the increased level may be obtained when the wireless communication switch disconnects the received signal amplification from the wireless module IC.

As an example, assuming a disconnection isolation of Zdbm, the receive signal amplifier includes two increasing levels: a first boost level and a second boost level, then the third power value at the first boost level may be obtained as: X-Y + G2-Z, and the third power value at the second increased level may be: X-Y + G1-Z, and two third power values are obtained.

Step 3044, controlling the wireless communication switch to disconnect the connection between the received signal amplifier and the wireless communication antenna, and setting the received signal amplifier based on the second tolerance value and the at least one third power value.

In this step, since the wireless communication switch has a large isolation degree in the off state, the power of the data communication signal is largely isolated after the wireless communication switch is controlled to disconnect the connection between the received signal amplifier and the wireless communication antenna, and therefore, the wireless module IC can be prevented from being damaged to a certain extent by controlling the wireless communication switch to disconnect the connection between the received signal amplifier and the wireless communication antenna. Further, since the connection between the received signal amplifier and the wireless communication antenna is disconnected, the received signal through the wireless communication antenna is reduced greatly, and therefore, in order to reduce the influence on the wireless communication quality as much as possible, in the embodiment of the present invention, the received signal amplifier may be further set based on the second tolerance value and the third power value. Specifically, the setting of the received signal amplifier based on the third power value corresponding to each increase level may be realized by the following substeps (1) to (2) or substep (3):

substep (1): and if a target third power value smaller than the second tolerance value exists in at least one third power value, taking the maximum value of the target third power values as a target power value.

In this step, each third power value may be compared with the second tolerance value to determine a target third power value smaller than the second tolerance value, and then, a maximum value is selected as the target power value from the target third power values smaller than the second tolerance value. For example, assume that the third power value: X-Y + G1-Z is less than N, X-Y + G2-Z is less than N, there are two target third power values less than the second tolerance value, and X-Y + G1-Z can be taken as the target power value because X-Y + G1-Z is greater than X-Y + G2-Z. For another example, assume that the third power value: X-Y + G1-Z is not less than N, X-Y + G2-Z is less than N, there is a target third power value less than the second tolerance value, and therefore, X-Y + G2-Z can be taken as the target power value.

Substep (2): and setting the increasing level of the receiving signal amplifier as the increasing level corresponding to the target power value.

For example, assuming that X-Y + G2-Z is the target power value, the increase level of the received signal amplifier may be set to a first increase level corresponding to X-Y + G2-Z, that is, in the case where X-Y < M and X-Y + G2-Z < N ≦ X-Y + G1-Z, the wireless module IC may be prevented from being damaged while ensuring the wireless communication quality by setting the received signal amplifier to a low gain mode and controlling the wireless communication switch to disconnect the received signal amplifier from the wireless communication antenna. Further, assuming that X-Y + G1-Z is the target third power value, the increase level of the received signal amplifier may be set to a second increase level corresponding to X-Y + G1-Z, that is, in the case where X-Y < M and X-Y + G1-Z < N, by setting the received signal amplifier to a high gain mode and controlling the wireless communication switch to disconnect the received signal amplifier from the wireless communication antenna, the wireless communication quality is ensured as much as possible while preventing the wireless module IC from being damaged.

In the embodiment of the present invention, the increase level corresponding to the maximum value in the target third power value is set as the increase level of the received signal amplifier, and the received signal amplifier is controlled to be disconnected from the wireless communication antenna, so that a high power gain is set for the received signal amplifier as much as possible while the wireless module IC is not damaged, thereby reducing the influence on the wireless communication quality due to the disconnection between the received signal amplifier and the wireless communication antenna, and ensuring the quality of the wireless communication as much as possible. In an actual application scenario, a table may be prepared in advance based on the foregoing size relationship between X-Y and M and its corresponding control manner, the size relationship between X-Y + G1 and X-Y + G2 and N and its corresponding control manner, and the size relationship between X-Y + G1-Z and X-Y + G2-Z and N and its corresponding control manner, and stored in the CPU of the terminal, so that the terminal may perform corresponding control according to different situations through the CPU.

Substep (3): setting the received signal amplifier to a pass-through mode if there is no target third power value of the at least one third power value that is less than the second tolerance value.

In this step, the through mode indicates an increase level at which the power increment of the received signal is 0, that is, a mode corresponding to no increase of the received signal, and further, if a target third power value smaller than the second tolerance value does not exist in the at least one third power value, it is considered that there is a risk that the wireless module IC may be damaged even if the power increment of the received signal amplifier is controlled to reach the minimum increment and the connection between the received signal amplifier and the wireless communication antenna is disconnected.

For example, fig. 3-2 is a partial schematic diagram of a circuit in a terminal according to an embodiment of the present invention, as shown in fig. 3-2, the terminal includes a CPU, a data communication module, a data communication antenna, a received signal amplifier, a wireless module IC, a wireless communication antenna, and a wireless communication switch, where the terminal may be controlled by the CPU, the data communication module includes a signal transceiver and a signal power amplifier, the terminal may transmit a data communication signal through the data communication antenna by using the data communication module, the wireless module IC may be configured to modulate and demodulate a wireless communication signal, and in an actual application scenario, the received signal amplifier may be an independent device or a module integrated in an integrated circuit and configured to amplify the received wireless communication signal.

Specifically, the CPU may be connected to a first end of the signal transceiver, a second end of the signal transceiver may be connected to a first end of the signal power amplifier, a second end of the signal power amplifier may be connected to a third end of the signal transceiver through a sampling wire, a second end of the signal power amplifier may be connected to the data communication antenna, and the signal power amplifier may send the acquired sampling signal to the signal transceiver through the sampling wire.

Further, the terminal may further include a control circuit, the CPU may be connected to the control circuit, the control circuit may be connected to the first end of the received signal amplifier, the second end of the received signal amplifier is connected to the wireless module IC, the third end of the received signal amplifier is connected to the first end of the wireless communication switch, the control circuit is connected to the second end of the wireless communication switch, the third end of the wireless communication switch is connected to the wireless communication antenna, the CPU controls the wireless communication switch through the control circuit, and sets the received signal amplifier through the control circuit.
