In the field of communications, in order to support network coverage of different operators, antennas supporting up to ten frequency bands are often required on a metal frame of an electronic device. Such as LTE low, medium and high frequency antennas; an antenna of NR 5G such as a new frequency n78, n79, etc. or a spectrum re-cultivation frequency n1, n3, n7, etc.; WIFI/GPS/NFC antennas for short-range communications, etc. Therefore, the layout space of the antennas in the electronic equipment is more and more limited, and on the basis of ensuring that the transmission and reception performance indexes of each antenna are all compliant, the isolation between the antennas is difficult to ensure, so that the risk of blocking a potential passage or damaging a device is avoided. Based on this, in order to improve the problems of via blocking and via device damage, the present application provides an electronic apparatus, a communication system, a communication method, a computer apparatus, and a computer storage medium.

Fig. 1 is a block diagram of an electronic device according to an embodiment, referring to fig. 1, in this embodiment, the electronic device includes: the first rf circuit 10, the second rf circuit 20 and the control circuit (in the figure, the antennas that are connected by conducting the first rf circuit 10 and the second rf circuit 20 are shown as examples, such as ANT1 and ANT2 in the figure, which are not limiting, meanwhile, only the connection state between the first rf circuit 10 and the second rf circuit 20 and the antennas is shown at a certain moment, the control circuit is not shown, the dotted line represents that the connection between the rf circuit and the antennas is in the disconnection state at the moment, and the solid line represents that the connection between the rf circuit and the antennas is in the conduction state at the moment).

A first radio frequency circuit 10 for supporting reception of satellite positioning signals when connected to the antenna in a conductive manner; a second radio frequency circuit 20 for supporting transmission of satellite communication signals to a target communication satellite when connected to the antenna in a conductive manner; the control circuit is respectively connected with the first radio frequency circuit 10 and the second radio frequency circuit 20 and is used for controlling connection and conduction between the first radio frequency circuit 10 and the antenna under a target scene, wherein the target scene comprises at least one of a satellite communication emission scene and a satellite positioning scene; and the electronic device is further used for determining the position information of the electronic device according to the satellite positioning signal in a satellite positioning scene, determining a target communication satellite in a satellite communication scene, controlling the connection between the first radio frequency circuit 10 and the antenna to be disconnected, and controlling the connection between the second radio frequency circuit 20 and the antenna to be conducted.

When the first radio frequency circuit 10 is connected to the antenna in a conductive manner, both the satellite communication transmission scene and the satellite positioning scene can support the reception of satellite positioning signals to assist positioning and searching satellites, specifically, in the satellite communication transmission scene, the satellite positioning signals can be used for a control circuit to determine a target communication satellite in a plurality of satellites, so that the electronic equipment performs satellite communication with the target communication satellite; in a satellite positioning scene, the satellite positioning signals can be used for a control circuit to determine the current position information of the electronic equipment so as to realize positioning and navigation functions.

Optionally, according to different usage scenarios of the user, the geographic area in which the electronic device is located may be different, and the visible satellites corresponding to different areas may be different, so the control circuit may determine the current position information of the electronic device according to the satellite positioning signal in the satellite positioning scenario, then determine the visible satellites in the target area according to the current position information, and then control the visible satellites in the target area of the first radio frequency circuit 10 to search for satellites during the satellite communication transmission scenario, so as to improve the efficiency of determining the target communication satellite.

Optionally, the satellite positioning signal may carry a data packet of satellite position information, and the control circuit may obtain position information of each satellite based on the data packet, determine distance information between the electronic device and each satellite according to the position information, and so on, so as to determine the target communication satellite and calculate current position coordinates of the electronic device according to the distance information corresponding to the plurality of satellites, so as to obtain current position information of the electronic device.

Wherein the second rf circuit 20, when in conductive connection to the antenna, supports transmitting satellite communication signals to the target communication satellite for communication with the target communication satellite. The satellite communication signal may, for example, carry call information to communicate with the master station via the target communication satellite. The satellite communication coverage capability is strong, and is not limited by the geographical environment, the climate condition and the time, so that the electronic device in the embodiment is integrated with the satellite communication function through the second radio frequency circuit 20, and the requirements of users can be met.

The control circuit is connected with the first radio frequency circuit 10 and the second radio frequency circuit 20 respectively, and based on the first radio frequency circuit 10 and the second radio frequency circuit 20, the control circuit can realize related control functions, auxiliary satellite searching functions, positioning functions and satellite communication functions:

on the one hand, the control circuit may determine the current scene type based on the received communication instruction, so as to implement the related control function according to the scene type, so as to control the connection states between the first radio frequency channel, the second radio frequency channel and the antenna respectively, specifically, whether in the satellite communication transmission scene or the satellite positioning scene, the first radio frequency circuit 10 may be controlled to be connected to the antenna in a conducting manner, the first radio frequency circuit 10 may be controlled to be disconnected from the antenna in the satellite communication transmission scene, and then the second radio frequency circuit 20 may be controlled to be connected to the antenna in a conducting manner, thereby, function matching under different scenes may be implemented, and meanwhile, the connection between the first radio frequency circuit 10 and the antenna may be timely disconnected when the second radio frequency circuit 20 is in the transmission state, so that the problems of channel blockage and even device damage caused by the transmission of the satellite communication signal by the first radio frequency circuit 10 are avoided, and the safety and stability of the circuit are improved.

On the other hand, the control circuit can also realize relevant auxiliary satellite searching function, positioning function and communication function based on the received satellite positioning signal, specifically, in the satellite communication transmission scene, the control circuit can determine a target communication satellite based on the satellite positioning signal so as to support the auxiliary satellite searching function together with the first radio frequency circuit 10; under the satellite communication emission scene, the control circuit also realizes communication connection with a target communication satellite based on a satellite communication signal, and then can realize communication connection with a main control station based on the target communication satellite, so that a communication function can be realized; in a satellite positioning scene, the control circuit can determine the current position information of the electronic equipment based on satellite positioning signals, so that the positioning navigation function can be realized.

It will be appreciated that the satellite communication signal of the second rf circuit 20 is adjacent to the frequency band of the satellite positioning signal of the first rf circuit 10, and the satellite communication signal is usually transmitted with high power, so that when the second rf circuit 20 transmits the satellite communication signal, the generated interference signal easily falls near the operating frequency band of the first rf circuit 10, and if no protection measures are taken, the interference will be blocked on the path where the first rf circuit 10 is located, and even the internal devices of the first rf circuit 10 are damaged. Jamming interference may be understood as the blocking of the receiver of the first radio frequency circuit 10 by satellite communication signals to demodulate satellite positioning signals.

The electronic device of the embodiment, through the first radio frequency circuit 10, the second radio frequency circuit 20 and the control circuit, can realize the switching control of the connection states between different radio frequency circuits and the antenna under different scenes, and realize the function matching under different scenes, and meanwhile, the first radio frequency circuit 10 can be disconnected with the antenna in time when the second radio frequency circuit 20 is in the transmitting state, so that the problems of channel blocking and even device damage caused by the transmission of satellite communication signals of the first radio frequency circuit 10 are avoided, and the safety and stability of the circuit are improved. Therefore, the electronic equipment of the embodiment can realize the protection of the radio frequency channel on the basis of realizing the satellite communication and satellite positioning functions, and improve the overall reliability, safety and stability, thereby improving the product yield, and reducing the customer return rate, the maintenance rate and the complaint rate, so as to improve the user experience. Meanwhile, the electronic equipment has simple structure and low cost, and can realize large-scale production.

In one embodiment, as shown in fig. 2, the electronic device further comprises a switching circuit 30.

The switch circuit 30 is respectively connected to the control circuit 40 (connection lines between the switch circuit 30 and the control circuit 40 are not shown in the figure), the first rf circuit 10, the second rf circuit 20, and the antenna, and is configured to switch the on-off state between each rf circuit and the antenna under the control of the control circuit 40.

The controlled end of the switch circuit 30 is connected to the control circuit 40, two first ends of the switch circuit 30 are respectively connected to the first rf circuit 10 and the second rf circuit 20, and the second end of the switch circuit 30 is connected to the antenna, so that the switch circuit 30 can switch the on-off state between each rf circuit and the antenna according to the control signal of the control circuit 40. Specifically, in a target scene, connection between a first radio frequency channel and an antenna is conducted; in the case of a satellite positioning scenario and a target communication satellite is determined, the connection between the first radio frequency circuit 10 and the antenna is disconnected and the connection between the second radio frequency circuit 20 and the antenna is turned on. Therefore, the control circuit 40 can assist to control the on-off states of the first radio frequency circuit 10, the second radio frequency circuit 20 and the antenna through the switch circuit 30, and on the basis of realizing function matching under different scenes and lower hardware cost, the problems of blocking a passage and even damaging devices caused by the transmission of satellite communication signals of the first radio frequency circuit 10 are avoided, and the safety, stability and reliability of the circuit are improved.

Alternatively, the switch circuit 30 may be connected to one antenna, so that the first rf circuit 10 and the second rf circuit 20 are respectively connected to the same antenna in a conductive manner at different times, so as to support the reception of satellite positioning signals and the transmission of satellite communication signals by the same antenna. Optionally, the switch circuit 30 may be connected to multiple antennas, and the first rf circuit 10 and the second rf circuit 20 may support conducting connection to the same antenna or different antennas at different times (fig. 2 illustrates connection to different antennas for illustration, but not limitation), so as to support receiving satellite positioning signals and transmitting satellite communication signals through the same or different antennas.

In one embodiment, as shown in fig. 3, the switching circuit 30 is connected to a first antenna (ANT 1 in the figure) and a second antenna (ANT 2 in the figure), and the switching circuit 30 includes: a first switch module 310 and a second switch module 320.

The first switch module 310 is respectively connected with the control circuit 40 (connection lines between each switch module and the control circuit 40 are not shown in the figure), the first radio frequency circuit 10 and the first antenna, and is used for conducting connection between the first radio frequency circuit 10 and the first antenna in a satellite communication transmission scene, and is also used for disconnecting connection between the first radio frequency circuit 10 and the first antenna in a satellite communication transmission scene and in a situation that the control circuit 40 determines a target communication satellite; the second switch module 320 is connected to the control circuit 40, the second rf circuit 20, and the second antenna, and is configured to conduct connection between the second rf circuit 20 and the second antenna when the satellite communication transmits a scene and the first switch module 310 disconnects the connection between the first rf circuit 10 and the first antenna.

The first switch module 310 is disposed on a connection path between the first rf circuit 10 and the first antenna, and the connection between the first rf circuit 10 and the first antenna can be controlled by controlling the on-off condition of the first switch module 310. The second switch module 320 is disposed on a connection path between the second rf circuit 20 and the second antenna, and the connection between the second rf circuit 20 and the second antenna can be controlled by controlling the on/off condition of the second switch module 320. By arranging the first switch module 310 and the second switch module 320, each switch module is arranged on the connection path between each radio frequency circuit and the antenna, so that the on and off conditions of each switch module can be independently controlled, and the radio frequency path can be switched more accurately. Alternatively, each switching module comprises a switching device, which may be, for example, a single pole single throw switch.

Alternatively, the control circuit 40 may output a first control signal to the first switch module 310 and the second switch module 320 to control the first switch module 310 and the second switch module 320 to be in a conductive state, respectively, and may output a second control signal to the first switch module 310 and the second switch module 320 to control the first switch module 310 and the second switch module 320 to be in an off state, respectively. Optionally, the control circuit 40 may be configured with a control interface, where the control interface includes one of a mipi (Mobile Industry Processor Interface ) interface and a GPIO (General Purpose Input Output, general purpose input/output) interface, and the control circuit 40 may send the first control signal and the second control signal to each switch module through level change control of the mipi interface or the GPIO interface, thereby improving control efficiency.

In one embodiment, as shown in fig. 4, the first switch module 310 is further connected to the ground plane (connection state of the control circuit and the switch circuit is not shown in the figure), and is further configured to conduct the connection between the first antenna and the ground plane in the case where the satellite communication transmission scenario is the satellite communication transmission scenario and the control circuit 40 determines the target communication satellite, so that when the second radio frequency circuit 20 transmits the satellite communication signal, the interference energy possibly received by the first antenna is released to the ground, so as to further ensure that the first radio frequency circuit 10 is not affected by the satellite communication signal transmitted by the second radio frequency circuit 20, and at the same time ensure that when the first radio frequency circuit 10 is subsequently connected to the first antenna in a re-conduction manner, the interference energy remains; in addition, under the condition of satellite communication scene, the first antenna is grounded, and the environment near the second antenna can be purer, so that the directivity of the second antenna when transmitting communication signals is more concentrated, the antenna efficiency is higher, and the test value of TRP (Total Radiated Power, omnidirectional radiation power)/TIS (Total Isotropic Sensitivity, omnidirectional radiation sensitivity) is higher. Alternatively, the first switch module 310 may be a single pole double throw switch, thereby implementing a selective switching function between conducting the first antenna to the first radio frequency circuit 10 and to the ground plane. Alternatively, the first switching module 310 may be connected to the ground plane through an impedance matching of 50Ω, so that interference energy may be transferred to the ground in the circuit with maximum power, thereby reducing the residue of interference energy.

In one embodiment, as shown in fig. 5, the first radio frequency circuit 10 includes: a first filtering module 110, a low noise amplifying module 120 and a second filtering module 130.

The first filtering module 110 is connected to the switch circuit 30, and is configured to perform filtering processing on the satellite positioning signal received by the antenna when the first filtering module is connected to the antenna in a conducting manner; the low-noise amplification module 120 is connected with the first filtering module 110, and is used for performing low-noise amplification on the satellite positioning signal filtered by the first filtering module 110; the second filtering module 130 is connected to the low noise amplifying module 120 and the control module, respectively, and is configured to perform filtering processing on the satellite positioning signal subjected to the low noise amplifying processing.

The first filtering module 110 and the second filtering module 130 are respectively configured to perform filtering processing on the received signals, specifically, the first filtering module 110 is configured to perform primary filtering processing on the received satellite positioning signals, and the second filtering module 130 is configured to perform secondary filtering processing on the received satellite positioning signals, so that the sensitivity and accuracy of the satellite positioning signals can be improved through dual filtering processing, and the accuracy of satellite positioning and target communication satellite determination can be improved. The low noise amplifier is connected to the first filtering module 110 and the second filtering module 130, and is configured to perform low noise amplification on the satellite positioning signal after the primary filtering process of the first filtering module 110, and output the satellite positioning signal to the second filtering module 130. Thus, the first filtering module 110, the low noise amplifying module 120 and the second filtering module 130 implement receiving processing of the satellite positioning signal. Alternatively, each filtering module may include a filter (SAW, surface Acoustic Wave Filter), and the low noise amplifying module 120 may include a low noise amplifier (LAN, low Noise Amplifier).

In the related art, the sustainable power range of the filter and the low noise amplifier is generally small, for example, the sustainable power range of the filter is 13dbm, and the sustainable power range of the low noise amplifier is 10dbm; the transmission power of the satellite communication signal is usually larger than the tolerable power range of the filtering module, for example, 36dbm may be reached, so that if no protection measures are taken, the filter and the low noise amplifier may be damaged during the transmission of the satellite communication signal. The on-off state of each radio frequency circuit and each antenna is switched based on the control circuit 40 and the switch circuit 30, so that the potential damage risk of the filter and the low-noise amplifier can be effectively avoided.

In one embodiment, the number of first rf circuits 10 is plural, or the electronic device also includes other rf circuits. Taking the plurality of first rf circuits 10 as an example, the electronic device may further include a combining module connected to the switch circuit 30 and the plurality of first rf circuits 10, respectively, for performing a combining process on the satellite positioning signals received by the antenna when the antenna is connected to the antenna, and outputting the satellite positioning signals to each of the first rf circuits 10 correspondingly.

The combining module may perform a combining processing function (it may be understood that, when receiving a signal, the combining processing function may be understood as splitting the received signal to obtain signals in different frequency bands) so as to respectively and correspondingly transmit the obtained signals in different frequency bands to each first radio frequency circuit 10, and on the other hand, the bearable power range of the combining module is generally higher than that of the filtering module, and by setting the combining module located at the front end (near the antenna side), suppression of interference blocking may be further implemented, for example, the combining module may be 16dbm and may suppress 3dbm.

In one embodiment, the second radio frequency circuit 20 includes: and the power amplification module is used for receiving the satellite communication signals to be transmitted, carrying out power amplification processing on the satellite communication signals and outputting the satellite communication signals to the antenna which is connected in a conducting mode. The Power amplification module may include a Power Amplifier (PA) or other functional devices to implement other auxiliary functions, for example, a low noise amplifier to implement a receiving function at the same time. When the power amplification module further includes a low noise amplifier, the power amplification module may be a power amplifier module (L-pa·mid, pa·mid With LNA) With a built-in low noise amplifier, or may be a power amplifier switching module (LPAF, LNA-PA ASM module With integrated filter) With a filter and a low noise amplifier integrated therein.

The radio frequency transceiver 410 is connected to the first radio frequency circuit 10 and the second radio frequency circuit 20, and is configured to receive the satellite positioning signal received and processed by the first radio frequency circuit 10, and output a satellite communication signal to be transmitted to the second radio frequency circuit 20; the control module 420 is connected with the radio frequency transceiver 410, and is used for determining a target scene according to the received control instruction, and controlling the on-off state of the switch circuit 30 according to the target scene; the method comprises the steps of analyzing satellite positioning signals received by the radio frequency transceiver 410 according to control instructions to determine a target communication satellite or determine current position information of the electronic equipment; and is further configured to control the rf transceiver 410 to output satellite communication signals according to the control instruction in case the target communication satellite is determined.

The radio frequency transceiver 410 is configured to implement a transceiving process, and may include a receiver for receiving a signal and a transmitter for outputting a signal to be transmitted, and specifically, the receiver of the radio frequency transceiver 410 may be connected to a receiving output end of the first radio frequency circuit 10 and the control module 420, respectively, so as to receive a satellite positioning signal received by the first radio frequency circuit 10, and output satellite positioning to the control module 420; the transmitter of the rf transceiver 410 may be respectively connected to the transmission input terminal of the second rf circuit 20 and the control module 420, so as to output the satellite communication signal output by the control module 420 to the second rf circuit 20.

The control module 420 is connected to the radio frequency transceiver 410, and the control module 420 can receive a control instruction input by a user, and can also obtain a working state of each radio frequency circuit and related radio frequency signals based on the radio frequency transceiver 410, and realize direct control or indirect control on the on-off state of the switch circuit according to the related control instruction. For example, the control module 420 may be connected to the switching circuit to directly control the on-off state of the switching circuit; for example, the control module 420 may be connected to the switch circuit through the rf transceiver 410, and the control module 420 may instruct the rf transceiver 410 to control the on-off state of the switch circuit by outputting a control command to the rf transceiver 410.
