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.
The antenna control method of the embodiment of the invention can be applied to a terminal comprising an antenna system, wherein the antenna system comprises a first antenna and a second antenna, the first antenna can be used as a first main radio frequency antenna and a Global Positioning System (GPS) antenna, namely, the antenna system of the terminal realizes the common antenna design of the first main radio frequency antenna and the GPS antenna, and can simultaneously process a first main radio frequency signal and a GPS signal through the first antenna; the second antenna may be used as the second main rf antenna, i.e. the second antenna may process the second main rf signal. Therefore, through the design, the antenna system of the terminal provided by the embodiment of the invention can realize the GPS performance while realizing the main radio frequency performance.
The terminal may be any Device including the above antenna system, such as a Mobile phone, a tablet personal Computer (tablet personal Computer), a laptop Computer (L ap Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and may also be an HPUE (High Power User Equipment).
The following describes an antenna control method according to an embodiment of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an antenna control method according to an embodiment of the present invention. As shown in fig. 1, an antenna control method according to an embodiment of the present invention may include the following steps:
and 101, acquiring target communication parameters of the terminal.
The target communication parameter may include, but is not limited to, a transmission power of an antenna system of the terminal or a target network system in which the terminal is located.
And 102, selecting one of the first main radio frequency antenna and the second main radio frequency antenna as a diversity antenna and the other one as a main set antenna based on the target communication parameters.
In specific implementation, the terminal may select one of the first main rf antenna and the second main rf antenna as a diversity antenna and the other as a main set antenna based on a specific expression of the target communication parameter, such as whether a target network system where the terminal is located is a preset network system or not, or whether a transmission power of an antenna system of the terminal is greater than a preset transmission power threshold. Therefore, the function of the main radio frequency antenna is matched with the concrete expression form of the target communication parameter of the terminal, and the reliability of the antenna system is further improved.
It should be understood that when one of the first main rf antenna and the second main rf antenna is used as a diversity antenna, the antenna used as the main rf antenna is only used for receiving the main rf signal; when the other of the first main rf antenna and the second main rf antenna serves as a main set antenna, the antenna serving as the main frequency antenna may be used to receive and transmit main rf signals.
In addition, it should be noted that, when the first main rf antenna is used as the main set antenna or the diversity antenna, the first antenna only changes the function as the first main rf antenna, and may remain unchanged for the function as the GPS antenna.
The antenna control method of the embodiment is applied to a terminal comprising an antenna system, wherein the antenna system comprises a first antenna and a second antenna, the first antenna is used as a first main radio frequency antenna and a GPS antenna, and the second antenna is used as a second main radio frequency antenna; the method comprises the following steps: acquiring target communication parameters of the terminal; selecting one of the first primary radio frequency antenna and the second primary radio frequency antenna as a diversity antenna and the other as a primary set antenna based on the target communication parameters; the target communication parameters comprise the transmitting power of the antenna system or the target network system where the terminal is located. Therefore, the first main radio frequency antenna and the GPS antenna share the antenna design, so that the GPS performance can be realized; meanwhile, the invention can freely switch the functions of the first main radio frequency antenna and the second main radio frequency antenna based on the target communication parameters of the terminal, thereby improving the reliability of the antenna system.
In this embodiment of the present invention, the terminal may select one of the first main rf antenna and the second main rf antenna as a diversity antenna and the other one as a main set antenna based on the target communication parameter through various implementation manners, which are described in the following.
Implementation mode one
In this embodiment, optionally, the selecting one of the first main rf antenna and the second main rf antenna as a diversity antenna and the other as a main set antenna based on the target communication parameter includes:
and if the transmitting power of the antenna system is greater than a preset transmitting power threshold value, or the target network type belongs to a preset network type, selecting the first main radio frequency antenna as a diversity antenna, and selecting the second main radio frequency antenna as a main set antenna.
Selecting the first main radio frequency antenna as a diversity antenna, wherein in the application scene, the first antenna is used as the diversity antenna and a GPS antenna; and selecting the second main radio frequency antenna as a main set antenna, wherein in the application scene, the second antenna is used as the main set antenna.
For convenience of understanding, the following description will be made in terms of application scenarios in which the target communication parameters are expressed as a target network system in which the terminal is located and a transmission power of an antenna system of the terminal, respectively.
And applying the first scene and the target communication parameters to represent the transmitting power of the antenna system of the terminal.
In this application scenario, if the transmission power of the antenna system is greater than a preset transmission power threshold, the first main rf antenna is selected as a diversity antenna, and the second main rf antenna is selected as a main diversity antenna.
In the embodiment of the present invention, the first antenna may be designed as a first main rf antenna and a GPS antenna, that is, the first main rf antenna and the GPS antenna share an antenna, and therefore, it can be understood that the antenna system includes a GPS receiving circuit for processing a GPS signal received by the GPS antenna and a rf processing circuit for processing a rf signal received and/or transmitted by the first main rf antenna, which are both connected to the first antenna.
Assuming that the terminal uses the first main rf antenna as a main set antenna, that is, the first antenna is used as a main set antenna and a GPS antenna, when the first antenna is used to transmit an rf signal, the rf processing circuit is used to transmit the rf signal to be transmitted by the first antenna, and the signal of the rf processing circuit flows to the first antenna, so that during the transmission of the rf signal, part of the rf signal leaks to the GPS receiving circuit, which may affect the GPS receiving circuit.
Assuming that the terminal uses the first main rf as a diversity antenna, i.e. the first antenna serves as a main set antenna and a GPS antenna, the rf processing circuit is only used for transmitting the rf signal received by the first antenna. The radio frequency signal received by the first antenna and the GPS signal cannot interfere with each other, the GPS signal flows to the GPS receiving circuit from the first antenna, and the radio frequency signal flows to the radio frequency processing circuit from the first antenna, so that the GPS receiving circuit cannot be influenced.
In practical applications, the maximum bearing power of a target device in the GPS receiving circuit can be determined as the transmitting power threshold of the antenna system, wherein the target device is the device with the minimum maximum bearing power in all devices included in the GPS receiving circuit, exemplarily, the GPS receiving circuit comprises a first filter, a low Noise Amplifier (L Noise Amplifier, L NA) and a second filter, wherein the second filter is used for filtering out GPS out-of-band signals, the low Noise Amplifier is used for amplifying GPS signals, the first filter is used for filtering out other signals except the GPS signals again, and the maximum bearing powers of the first filter and the low Noise Amplifier are both greater than the maximum bearing power of the second filter, and then the terminal can determine the maximum bearing power threshold of the antenna system in the GPS receiving circuit.
In some embodiments, the transmit power threshold may be set to 25dBm (decibel-milliwatt), but is not limited thereto.
Therefore, if the transmitting power of the antenna system is detected to be larger than the preset transmitting power threshold value, it is indicated that the first main radio-frequency antenna is used as the main set antenna, which may cause the devices in the GPS receiving circuit of the antenna system to be damaged, and further affect the GPS performance of the antenna system, the first main radio-frequency antenna may be selected as the diversity antenna, and the second main radio-frequency antenna may be selected as the main set antenna, so that the devices in the GPS receiving circuit may be protected from being damaged.
If it is detected that the transmission power of the antenna system is smaller than the preset transmission power threshold, it is described that the first main radio-frequency antenna is used as the main set antenna, and a device in the GPS receiving circuit of the antenna system is not damaged, so that the terminal may determine, based on other selection rules, a function of the first antenna as the first main radio-frequency antenna and a function of the second antenna as the second main radio-frequency antenna, which may be specifically referred to the description in embodiment two and will not be described herein again.
And in the application scene II, the target communication parameters are expressed as a target network system where the terminal is located.
In this application scenario, if the target network type belongs to a preset network type, the first main radio frequency antenna is selected as a diversity antenna, and the second main radio frequency antenna is selected as a main diversity antenna.
The preset network system may include one or more network systems. It should be noted that, when the terminal is in the preset network system, the transmission power of the antenna system of the terminal may be greater than the transmission power threshold in the application scenario.
For example, the preset network System may include a GSM (Global System for mobile communication) network System, and when the terminal is in the GSM network System, the transmission power of the antenna System of the terminal may reach 33dBm or higher, which is greater than the transmission power threshold in the application scenario one, so that after a radio frequency signal to be transmitted enters the GPS receiving path, a device in the GPS receiving path may be damaged, and the GPS function of the antenna System may be permanently lost.
Therefore, when the target network system where the terminal is located is determined to be the preset network system, the terminal can directly select the first main radio frequency antenna as the diversity antenna and select the second main radio frequency antenna as the main diversity antenna. Therefore, the device in the GPS receiving circuit of the antenna system can be protected from being damaged, and the reliability of the GPS performance of the antenna system is improved.
In addition, different from the application scenario two in which the terminal is in the same preset network system, the functions of the first main radio frequency antenna and the second main radio frequency antenna are fixed, and in the application scenario one, if the transmission power of the antenna system of the terminal is greater than the transmission power threshold value at some time in the same preset network system, the first main radio frequency antenna can be selected as a diversity antenna, and the second main radio frequency antenna is selected as a main set antenna; at other times, the transmission power is less than or equal to the transmission power threshold, the function of the first antenna as the first main radio-frequency antenna and the function of the second antenna as the second main radio-frequency antenna can be determined based on other selection rules, that is, the functions of the first main radio-frequency antenna and the second main radio-frequency antenna can be switched by the terminal under the same preset network system, so that the reliability and the flexibility of the antenna system can be further improved.
Second embodiment
In this embodiment, optionally, the selecting one of the first main rf antenna and the second main rf antenna as a diversity antenna and the other as a main set antenna based on the target communication parameter includes:
if the transmitting power of the antenna system is smaller than or equal to a preset transmitting power threshold value, or the target network type does not belong to a preset network type, acquiring a first performance parameter value of the first main radio-frequency antenna and a second performance parameter value of the second main radio-frequency antenna;
selecting a main radio frequency antenna corresponding to the first target parameter value as a main set antenna, and selecting a main radio frequency antenna corresponding to the second target parameter value as a diversity antenna;
wherein the first target parameter value is a larger value of the first performance parameter value and the second performance parameter value, and the second target parameter value is a smaller value of the first performance parameter value and the second performance parameter value.
During specific implementation, if the first target parameter value is a first performance parameter value and the second target parameter value is a second performance parameter value, selecting the first main radio-frequency antenna as a main set antenna, and in the application scene, using the first antenna as the main set antenna and the GPS antenna; and selecting the second main radio frequency antenna as a diversity antenna, wherein the second antenna is used as the diversity antenna in the application scene.
If the first target parameter value is a second performance parameter value and the second target parameter value is a first performance parameter value, selecting the first main radio frequency antenna as a diversity antenna, and in the application scene, using the first antenna as the diversity antenna and the GPS antenna; and selecting a second main radio frequency antenna as a main set antenna, wherein the second antenna is used as the main set antenna in the application scene.
In this embodiment, the performance parameter of the main rf antenna may be any downlink communication parameter, such as received signal strength, received signal quality, or received signal power. It should be understood, however, that the first performance parameter value of the first primary rf antenna and the second performance parameter value of the second primary rf antenna correspond to the same downlink communication parameter. Illustratively, if the first performance parameter value corresponds to a received signal strength of the first primary rf antenna, then the second performance parameter value corresponds to a received signal strength of the second primary rf antenna, accordingly.
The first target parameter value is the larger value of the first performance parameter value and the second performance parameter value, and the second target parameter value is the smaller value of the first performance parameter value and the second performance parameter value, so that the antenna performance of the main radio frequency antenna corresponding to the first target parameter value is stronger than the antenna performance of the main radio frequency antenna corresponding to the second target parameter value. Therefore, the main radio frequency antenna corresponding to the first target parameter value is selected as the main set antenna, and the main radio frequency antenna corresponding to the second target parameter value is selected as the diversity antenna, so that the communication quality of the antenna system can be effectively improved, the probability of terminal disconnection or call drop is reduced, and the reliability of the antenna system can be improved.
It should be noted that the transmission power threshold in the second embodiment and the transmission power threshold in the first embodiment may be determined based on the same principle, and may be the same or different, and similarly, the preset network system in the second embodiment and the preset network system in the first embodiment may be the same or different.
However, it should be understood that, when the first embodiment and the second embodiment are used in combination, the transmission power threshold in the second embodiment should be the same as the transmission power threshold in the first embodiment, and the preset network system in the second embodiment should also be equivalent to the preset network system in the first embodiment, so as to ensure the consistency of the determination and improve the accuracy.
It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
The embodiment of the invention also provides an antenna system which can be applied to a terminal and is used for realizing the antenna control method. Referring to fig. 2, fig. 2 is a schematic structural diagram of an antenna system according to an embodiment of the present invention.
As shown in fig. 2, the antenna system includes a first antenna 21, a second antenna 22, a GPS extraction module 23, a GPS receiving circuit 24, an antenna switching module 25, a radio frequency transceiver circuit 26, a radio frequency receiving circuit 27, and a main radio frequency module 28;
wherein, the first antenna 21 is used as a first main radio frequency antenna and a GPS antenna; the second antenna 22 acts as a second main rf antenna;
the radio frequency transceiver circuit 26 is connected with the first antenna 21 through the antenna switching module 25 and the GPS extraction module 23 in sequence; the radio frequency transceiver circuit 26 is connected with the second antenna 22 through the antenna switching module 25;
the radio frequency receiving circuit 27 is connected with the first antenna 21 through the antenna switching module 25 and the GPS extraction module 23 in sequence; the radio frequency receiving circuit 27 is connected with the second antenna 22 through the antenna switching module 25;
the GPS receiving circuit 24 is connected with the first antenna 21 through the GPS extraction module 23;
the antenna switching module 25 is connected to the main rf module 28.
As shown in fig. 2, the first antenna 21 receives a main rf frequency band, and after passing through the GPS extraction module 23, the GPS extraction module 23 divides the signal into two paths, one path is a GPS signal, and the other path is a main rf signal.
The GPS signal passing through the GPS extraction module 23 enters the GPS receiving circuit 24, and the GPS receiving circuit 24 processes the GPS signal, such as filtering out other signals, amplifying the GPS signal, and then enters the GPS signal processor in the main rf module 28 for subsequent signal processing.
The main rf signal passing through the GPS extraction module 23 enters the antenna switching module 25. It should be understood that the antenna switching module 25 has at least two conducting states, so that the main rf module 28 can control the antenna switching module 25 to be in different conducting states, and further control whether the main rf signal enters the rf transceiver circuit 26 or the rf receiver circuit 27.
For example, if the main rf module 28 controls the antenna switching module 25 to be in the first conducting state, and it is assumed that the antenna switching module 25 conducts the GPS extraction module 23 and the rf transceiver circuit 26, and the second antenna 22 and the rf receiving circuit 27 under the condition that the antenna switching module 25 is in the first conducting state, the main rf signal received by the first antenna 21 enters the main rf module 28 through the rf transceiver circuit 26, and the main rf signal received by the second antenna 22 enters the main rf module 28 through the rf receiving circuit 27. It can be seen that in this application scenario, the first main rf antenna is selected as the main set antenna, the second main rf antenna is selected as the diversity antenna, that is, the first antenna 21 is used as the main set antenna and the GPS antenna, and the second antenna is used as the diversity antenna.
If the main rf module 28 controls the antenna switching module 25 to be in the second conducting state, and if the antenna switching module 25 is in the second conducting state, the antenna switching module 25 conducts the GPS extraction module 23 and the rf receiving circuit 27, and the second antenna 22 and the rf transceiver circuit 26, the main rf signal received by the first antenna 21 enters the main rf module 28 through the rf receiving circuit 27, and the main rf signal received by the second antenna 22 enters the main rf module 28 through the rf transceiver circuit 26. It can be seen that in this application scenario, the first main rf antenna is selected as a diversity antenna, the second main rf antenna is selected as a main set antenna, that is, the first antenna 21 is used as a diversity antenna and a GPS antenna, and the second antenna 22 is used as a main set antenna.
Through the antenna system, the main radio frequency module can control a main radio frequency signal to enter the radio frequency transceiving circuit or the radio frequency receiving circuit by controlling the antenna switching module to be in different conduction states, so that one of the first main radio frequency antenna and the second main radio frequency antenna is selected as a diversity antenna, the other one of the first main radio frequency antenna and the second main radio frequency antenna is selected as a main diversity antenna, the function switching of the first main radio frequency antenna and the second main radio frequency antenna is realized, and the reliability of the antenna system can be improved.
In practical applications, as shown in fig. 3, the antenna switching module 25 may be a DPDT (Double pole Double Throw) switch. Specifically, the DPDT switch may include a first single-pole double-throw switch and a second single-pole double-throw switch, a control end of the first single-pole double-throw switch is connected to the GPS decimation module 23, and two ports of the first single-pole double-throw switch for switching connection are respectively connected to the radio frequency transceiver circuit 26 and the radio frequency receiver circuit 27; the control terminal of the second single-pole double-throw switch is connected with the second antenna 22, and two ports of the second single-pole double-throw switch for switching connection are respectively connected with the radio frequency transceiver circuit 26 and the radio frequency receiver circuit 27.
Thus, if the main rf module 28 controls the control end of the first single-pole double-throw switch to connect with the port of the first single-pole double-throw switch, which is connected with the rf transceiver circuit 26, the GPS extraction module 23 and the rf transceiver circuit 26 are turned on, and the rf signal received by the first antenna 21 is controlled to enter the rf transceiver circuit 26; meanwhile, the main rf module 28 controls the control terminal of the second single-pole double-throw switch to connect with the port of the second single-pole double-throw switch, which is connected with the rf receiving circuit 27, so as to turn on the second antenna 22 and the rf receiving circuit 27, and control the rf signal received by the second antenna 22 to enter the rf receiving circuit 27. It can be seen that in this application scenario, the antenna system selects the first main rf antenna as a main set antenna, the second main rf antenna as a diversity antenna, that is, the first antenna 21 serves as the main set antenna and the GPS antenna, and the second antenna serves as the diversity antenna.
If the main rf module 28 controls the control end of the first single-pole double-throw switch to connect with the port of the first single-pole double-throw switch, which is connected with the rf receiving circuit 27, the GPS extraction module 23 and the rf receiving circuit 27 are turned on, and the rf signal received by the first antenna 21 is controlled to enter the rf receiving circuit 27; meanwhile, the main rf module 28 controls the control terminal of the second single-pole double-throw switch to connect with the port of the second single-pole double-throw switch, which is connected with the rf transceiver circuit 26, so as to turn on the second antenna 22 and the rf transceiver circuit 26, and control the rf signal received by the second antenna 22 to enter the rf transceiver circuit 26. It can be seen that in this application scenario, the antenna system selects the first main rf antenna as a diversity antenna, the second main rf antenna as a main set antenna, that is, the first antenna 21 serves as a diversity antenna and a GPS antenna, and the second antenna serves as a main set antenna.
In this way, the main rf module may control a first main rf signal received by the first antenna or a second main rf signal received by the second antenna to enter the rf transceiver circuit through a connection relationship between a control terminal of each single-pole double-throw switch in the DPDT switch and two ports connecting the rf transceiver circuit 26 and the rf receiver circuit 27, so as to select one of the first main rf antenna and the second main rf antenna as a diversity antenna and the other one as a main set antenna, thereby implementing function switching between the first main rf antenna and the second main rf antenna, and improving reliability of the antenna system.
Of course, in other embodiments, the antenna switching module 25 may also be represented by other devices, such as an electronic chip switch, and the like, which may be determined according to actual needs, and is not limited in this embodiment of the present invention.
Further, as shown in fig. 3, the GPS receiving circuit 24 may include a first filter 241, a low Noise Amplifier (L ow Noise Amplifier, L NA)242 and a second filter 243 connected in series in sequence, wherein the first filter 241 is connected to the main rf module 28, the second filter 243 is connected to the GPS decimation module 23, the second filter 243 is used for filtering out GPS out-of-band signals, the low Noise Amplifier 242 is used for amplifying GPS signals, and the first filter 241 is used for filtering out other signals besides GPS signals again.
The rf transceiver circuit 26 may include a PA (Power Amplifier) module 261 and a main switch 262. The PA module 261 and the main switch 262 form a sub-rf transmitting circuit of the rf transceiver circuit 26, and the main switch forms a sub-rf receiving circuit of the rf transceiver circuit 26. The radio frequency receive circuit 27 may include a diversity switch 271. The GPS extraction module 23 may be embodied as a GPS extractor.
Further, in some embodiments, the antenna system may further include a WIFI/BT individual antenna design, and a signal received by the WIFI/BT antenna enters the WCN (Windows Connect Now, Windows immediate Connect) module through the WIFI/BT antenna circuit. The WIFI/BT antenna circuit may include, but is not limited to, a filter.
In a specific application, the first antenna 21 may be an upper antenna of the terminal, such as disposed at an upper end of the terminal; the lower antenna of the terminal may be, for example, but not limited to, the lower antenna of the terminal.
The antenna switching module 25 and the main rf module 28 may be directly connected or indirectly connected through other elements, which is not limited herein.
