Description

Technical Field

[0001] This application claims the priority of Chinese Patent Application No. 202011158431.2, entitled "SATELLITE SEARCH METHOD AND APPARATUS", filed with the China National Intellectual Property Administration on October 26, 2020, which is incorporated herein by reference in its entirety.

[0002] This application relates to the field of communications, and in particular, to a satellite search method and apparatus.

Background Art

[0003] Satellite communication technology is a technology that uses artificial earth satellites as relay stations to realize communication between ground stations. Satellite communication technology has many advantages such as wide coverage, large communication capacity, good transmission quality, simple and fast networking, and easy and seamless global connection implementation. This can provide great convenience to mobile users. In order to establish a communication connection between a mobile terminal and a satellite, the signal quality of the communication between the mobile terminal and the satellite can be guaranteed only when there is no obstacle on the connection line between the antenna of the mobile terminal and the satellite (that is, there is a direct line of sight).

[0004] Currently, medium or large communication devices (where the device body is separated from the device's antenna) need to rely on external devices (such as satellite finders) to search for satellites. However, this method cannot be applied to the satellite search operation of mobile terminals (where the antenna of the mobile terminal is integrated with the mobile terminal body). In the case of a mobile terminal that supports satellite search, usually, the antenna needs to be installed outside the mobile terminal, or the antenna occupies a large space inside the mobile terminal. However, in this method, the device cost is high, the power consumption is high, and the size of the mobile terminal also becomes large. Currently, there is no satellite search method that is applicable to mobile terminals and has low cost, small size, and low power consumption.

Summary of the Invention

[0005] Embodiments of the present application solve the problems that the satellite search method cannot be applied to mobile terminals that can search for satellites or cannot be applied to mobile terminals, and that in a satellite search method applicable to mobile terminals, the antenna needs to be installed outside the mobile terminal or the antenna occupies a large space inside the mobile terminal, and provide a satellite search method and device in which the satellite search method is applicable to mobile terminals and the mobile terminals have low cost, small size, and low power consumption.

Means for Solving the Problems

[0006] To achieve the above object, the present application uses the following technical solutions.

[0007] According to a first aspect, the present application is a satellite search method applicable to a mobile terminal, including determining whether a direct line of sight between the mobile terminal and an available satellite is blocked by an obstacle based on the position information of the mobile terminal, the position information of the available satellite, and three-dimensional (3D) map information; and determining the position information of a target area based on the 3D map information when the direct line of sight is blocked by an obstacle, where the target area is an area where there is a direct line of sight between the mobile terminal and the available satellite.

[0008] Based on the satellite search method provided in the first aspect, it is determined that a direct line of sight between the mobile terminal and an available satellite is blocked by an obstacle based on the position information of the mobile terminal, the position information of the available satellite, and three-dimensional (3D) map information. The position information of the target area is determined based on the 3D map information. The target area is an area where there is a direct line of sight between the mobile terminal and the available satellite. In this way, the satellite search method is applicable to the mobile terminal, and there is no need to install an antenna outside the mobile terminal, nor does the antenna occupy a large space inside the mobile terminal. Therefore, the mobile terminal has low cost, small size, and low power consumption.

[0009] In one possible design, the target area may be an area where the distance from the mobile terminal is less than or equal to a preset distance. In this way, since the target area is an area where the distance from the mobile terminal is less than or equal to a preset distance, the time spent by the user to reach the target area from the location where the mobile terminal is located is the shortest. This improves the user's operation experience.

[0010] Optionally, the step of determining the position information of the target area based on the 3D map information may include a step of determining a candidate area, where the candidate area may be an area within a preset distance from the mobile terminal, and the candidate area may include a plurality of sub-areas, and a step of determining the target area based on the position information of at least one sub-area, the position information of available satellites, and the 3D map information, where the target area may be a sub-area among the plurality of sub-areas that has a direct line of sight to an available satellite.

[0011] Alternatively, optionally, the step of determining the position information of the target area based on the 3D map information may include a step of determining a first included angle between a first connection line and a second connection line based on the 3D map information, where the first connection line may be a connection line between the top of an obstacle and an available satellite, and the second connection line may be a connection line between the projection of the available satellite on the ground and the mobile terminal, and a step of determining the target area, where the target area may be located on the extension line of the second connection line and the difference between the first included angle and a second included angle is greater than an included angle threshold, and the second included angle may be an included angle between a third connection line and the extension line of the second connection line, and the third connection line may be a connection line between the available satellite and the extension line of the second connection line.

[0012] In one possible design, the satellite search method provided in the first aspect may further include a step of outputting navigation information, where the navigation information is used to move from the position corresponding to the position information of the mobile terminal to the target area based on the 3D map information. In this way, the navigation information can clearly instruct the user on how to reach the target area from the position of the mobile terminal, and the operation is simple. This improves the user experience.

[0013] In one possible design, the satellite exploration method provided in the first aspect includes, when the mobile terminal is already within the target area, the steps of obtaining the pose information of the mobile terminal, determining the maximum gain direction angle of the antenna of the mobile terminal based on the antenna pattern of the antenna and the pose information of the mobile terminal, determining the target direction angle of the available satellite based on the position information of the mobile terminal and the position information of the available satellite, determining a first pose adjustment parameter based on the difference between the maximum gain direction angle and the target direction angle, and outputting prompt information corresponding to the first pose adjustment parameter, where the prompt information is used to adjust the difference between the maximum gain direction angle and the target direction angle to be less than or equal to the angular threshold. In this way, the user can adjust the pose of the mobile terminal based on the output prompt information corresponding to the first pose adjustment parameter, which is simple and fast. In addition, the first pose adjustment parameter is determined with reference to the coefficient of the antenna pattern. Therefore, the reliability of the determined first pose adjustment parameter is also high.

[0014] In one possible design, the prompt information may include one or more of display information, pan-tilt-zoom control information, voice prompt information, or vibration prompt information.

[0015] In one possible design, the satellite search method provided in the first aspect includes establishing a communication connection between the mobile terminal and an available satellite when the difference between the maximum gain direction angle and the target direction angle is less than or equal to an angular threshold, determining a second pose adjustment parameter when the signal strength of the signal transmitted by the available satellite and received by the mobile terminal is less than or equal to an intensity threshold, and outputting second prompt information when the actual adjustment amount is greater than or equal to a preset adjustment amount. The actual adjustment amount is counted once each time the first pose adjustment parameter or the second pose adjustment parameter is determined, and the second prompt information may be information indicating satellite search failure. The method may further include the step of outputting second prompt information. Therefore, when the actual adjustment amount is greater than or equal to the preset adjustment amount, it indicates that the communication requirement between the mobile terminal and the available satellite cannot be satisfied by adjusting the pose of the mobile terminal at the current position. In this case, information indicating satellite search failure may be output to prompt the user to change the position. This avoids the waste of time caused by the user continuously adjusting the pose of the mobile terminal at the same location to search for satellites, improves the reliability of satellite search, and reduces the power consumption of the mobile terminal.

[0016] According to a second aspect, an embodiment of the present application further provides a satellite search device applicable to a mobile terminal, including a determination unit and an acquisition unit.

The acquisition unit is configured to acquire the position information of the target area based on the 3D map information when the direct line of sight is blocked by an obstacle. The target area may be an area where there is a direct line of sight between the mobile terminal and the available satellite.

[0017] Furthermore, the target area is an area where the distance from the mobile terminal is less than or equal to a preset distance.

[0018] Optionally, in one possible design, the acquisition unit is configured to determine a candidate area, which is an area where the distance from the mobile terminal is less than or equal to a preset distance. The candidate area includes a plurality of sub-areas, and the acquisition unit is further configured to acquire the position information of the target area based on the position information of at least one sub-area, the position information of the available satellites, and the 3D map information. The target area may be a sub-area among the plurality of sub-areas that has a direct line of sight to the available satellites.

[0019] Alternatively, optionally, in another possible design, the acquisition unit is configured to determine a first included angle between a first connection line and a second connection line based on the 3D map information. The first connection line may be a connection line between the top of the obstacle and the available satellite, and the second connection line may be a connection line between the projection of the available satellite on the ground and the mobile terminal. Then, the acquisition unit is further configured to acquire the position information of the target area, and the target area may be an area located on the extension line of the second connection line, where the difference between the first included angle and a second included angle is greater than the included angle threshold. The second included angle may be an included angle between a third connection line and the extension line of the second connection line, and the third connection line may be a connection line between the available satellite and the top of the obstacle.

[0020] In one possible design, the device further includes an output unit configured to output navigation information, where the navigation information is used to move from the position corresponding to the position information of the mobile terminal to the target area based on the 3D map information.

[0024] In one possible design, the device may further include a communication unit configured to establish a communication connection between the mobile terminal and the available satellite when the difference between the maximum gain direction angle and the target direction angle is less than or equal to the angular threshold. The determination unit is further configured to determine a second pose adjustment parameter when the signal strength of the signal transmitted by the available satellite and received by the mobile terminal is less than or equal to the strength threshold. The output unit is further configured to output second prompt information when the actual adjustment amount is greater than or equal to a preset adjustment amount. The actual adjustment amount is counted once each time the first pose adjustment parameter or the second pose adjustment parameter is determined. The second prompt information is information indicating a satellite exploration failure.

[0069] As shown in FIG. 2, the mobile terminal 101 in the embodiments of this application may be a mobile phone 200. The following uses the mobile phone 200 as an example to specifically describe the embodiments. The mobile phone 200 shown in the figure is only an example of the mobile terminal 101. It should be understood that the mobile phone 200 may have more or fewer components than those shown in the figure, may combine two or more components, or may have a configuration of different components.

[0070] As shown in FIG. 2, specifically, the mobile phone 200 may include components such as a processor 201, a radio frequency (RF) circuit 202, a memory 203, a touch screen 204, a Bluetooth (registered trademark) device 205, one or more sensors 206, a wireless fidelity (Wi-Fi) device 207, a positioning device 208, an audio circuit 209, a peripheral device interface 210, and a power supply device 211. These components may communicate via one or more communication buses or signal lines (not shown in FIG. 2). Those skilled in the art can understand that the hardware structure shown in FIG. 2 does not constitute any limitation to the mobile phone. The mobile phone 200 may include more or fewer components than those shown in the figure, may have some combined components, or may have an arrangement of different components.

[0071] The components of the mobile phone 200 will be specifically described below with reference to FIG. 2.

[0072] The processor 201 is the control center of the mobile phone 200. By using various interfaces and circuits, it connects various parts of the mobile phone 200, runs or executes the applications stored in the memory 203, and calls the data stored in the memory 203 to execute various functions of the mobile phone 200 and process data. In some embodiments of the present application, the processor 201 may further include a fingerprint verification chip configured to verify the collected fingerprints.

[0073] The radio frequency circuit 202 may be configured to receive and transmit radio signals in the information receiving and transmitting process or the call process (for example, perform signal interaction with the available satellite 102). In particular, after receiving the downlink data from the base station, the radio frequency circuit 202 can transmit the downlink data to the processor 201 for processing and can transmit the uplink data to the base station. The radio frequency circuit usually includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency circuit 202 can further communicate with another device via wireless communication. The wireless communication may use any wireless communication standard or communication protocol including, but not limited to, Global System for Mobile Communications, General Packet Radio Service, Code Division Multiple Access, Wideband Code Division Multiple Access, Long Term Evolution, email, Short Message Service, etc.

[0074] The memory 203 is configured to store applications and data. The processor 201 executes various functions of the mobile phone 200 and processes data by running the applications and data stored in the memory 203. The memory 203 mainly includes a program storage area and a data storage area. The program storage area may store an operating system and applications required by at least one function (such as an audio playback function and an image playback function). The data storage area may store data created based on the use of the mobile phone 200 (such as audio data and a phone book). In addition, the memory 203 may include a high-speed random access memory (RAM), and may further include a non-volatile memory such as a magnetic disk storage device, a flash memory, or another volatile solid-state storage device. The memory 203 may store various operating systems such as the iOS (registered trademark) operating system developed by Apple and the Android (registered trademark) operating system developed by Google. The memory 203 may be independent, connected to the processor 201 by using a communication bus, or the memory 203 may be integrated with the processor 201.

[0075] The touch screen 204 may specifically include a touch panel 204-1 and a display 204-2.

[0076] The touch panel 204-1 can collect touch operations (for example, operations performed on or near the touch panel 204-1 by the user of the mobile phone 200 using an arbitrary applicable object such as a finger or a stylus), and transmit the collected touch information to another device (for example, the processor 201). The touch operation near the touch panel 204-1 by the user may be called hover touch. Hover touch can mean that the user is not required to directly touch the touch panel to select, move, or drag a target (for example, the control unit), but only needs to stay near the terminal to perform the intended function. In addition, the touch panel 204-1 may be implemented in multiple types such as resistive type, capacitive type, infrared type, surface acoustic wave type, etc.

[0077] The display (also known as a display) 204-2 may be configured to display information input by or provided to the user, as well as various menus of the mobile phone 200. The display 204-2 may be configured in the form of a liquid crystal display or an organic light emitting diode, etc. The touch panel 204-1 may cover the display 204-2. After detecting a touch event on or near the touch panel 204-1, the touch panel 204-1 transmits the touch event to the processor 201 in order to determine the type of the touch event. The processor 201 can then provide a corresponding visual output on the display 204-2 based on the type of the touch event. In FIG. 2, the touch panel 204-1 and the display 204-2 are used as two independent components that implement the input and output functions of the mobile phone 200. However, in some embodiments, the touch panel 204-1 and the display 204-2 may be integrated to implement the input and output functions of the mobile phone 200. It can be understood that the touch screen 204 can be formed by stacking a plurality of material layers. Only the touch panel (layer) and the display (layer) are presented in the present embodiment of this application. Other layers are not described in the present embodiment of this application. In addition, the touch panel 204-1 may be arranged on the front surface of the mobile phone 200 in the form of a full panel, and the display 204-2 may also be arranged on the front surface of the mobile phone 200 in the form of a full panel. In this way, a bezel-free structure can be implemented on the front surface of the mobile phone 200.

[0078] In addition, the mobile phone 200 may further have a fingerprint authentication function. For example, the fingerprint collection component 212 may be configured on the back surface of the mobile phone 200 (for example, under the rear-facing camera), or the fingerprint collection component 212 may be configured on the front surface of the mobile phone 200 (for example, under the touch screen 204). As another example, the fingerprint collection component 212 may be configured in the touch screen 204 to implement the fingerprint recognition function. That is, the fingerprint collection component 212 may be integrated with the touch screen 204 to implement the fingerprint recognition function of the mobile phone 200. In this case, the fingerprint collection component 212 may be configured in the touch screen 204 to become a part of the touch screen 204, or may be configured in the touch screen 204 in another way. In the embodiments of the present application, the main component of the fingerprint collection component 212 is a fingerprint sensor. The fingerprint sensor can use any type of sensing technology including, but not limited to, optical technology, capacitive technology, piezoelectric technology, ultrasonic technology, etc.

[0079] The mobile phone 200 may further include a Bluetooth (registered trademark) device 205 configured to perform data exchange (for example, receiving and transmitting the translated text and the original text) between the mobile phone 200 and another short-range terminal (for example, a mobile phone or a smartwatch). In the present embodiment of the present application, the Bluetooth (registered trademark) device 205 may be an integrated circuit, a Bluetooth (registered trademark) chip, etc.

[0080] The mobile phone 200 may further include at least one type of sensor 206, such as an optical sensor, a motion sensor, and other sensors. Specifically, the optical sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display of the touch screen 204 according to the brightness of the ambient light, and the proximity sensor can turn off the display when the mobile phone 200 moves close to the ear. As for the type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in various directions (typically three axes), and can detect the magnitude and direction of gravity in the stationary state, and can be applied to the pose recognition applications of the mobile phone (such as landscape / portrait switching, related games, and magnetometer pose calibration), and vibration recognition related functions (such as pedometer or knock recognition). Details of other sensors such as gyroscope, barometer, hygrometer, thermometer, and infrared sensor that can be further configured in the mobile phone 200 are not described here.

[0081] The Wi-Fi device 207 is configured to provide the mobile phone 200 with network access that meets Wi-Fi related standard protocols. The mobile phone 200 can access a Wi-Fi access point by using the Wi-Fi device 207 to assist the user in sending and receiving information and provide the user with wireless broadband Internet access. In some other embodiments, the Wi-Fi device 207 can also function as a Wi-Fi wireless access point that provides Wi-Fi network access to another terminal.

[0082] The positioning device 208 is configured to provide the geographical location to the mobile phone 200. It can be understood that the positioning device 208 can specifically be a receiver of a positioning system such as the global positioning system (GPS), the BeiDou navigation satellite system, or GLONASS of Russia. After receiving the geographical location transmitted by the aforementioned positioning system, the positioning device 208 transmits the information to the processor 201 for processing or transmits the information to the memory 203 for storage. In some other embodiments, the positioning device 208 may alternatively be a receiver of an assisted global positioning system (AGPS). The AGPS system functions as an assisting server to assist the positioning device 208 in completing ranging and positioning services. In this case, the assisting positioning server communicates with the positioning device 208 (i.e., the GPS receiver) of the terminal, such as the mobile phone 200, via a wireless communication network to provide positioning assistance. In some other embodiments, the positioning device 208 may alternatively be a positioning technology based on Wi-Fi access points. Each Wi-Fi access point has a globally unique media access control (MAC) address, and the terminal can scan and collect the broadcast signals of the nearby Wi-Fi access points when the terminal has Wi-Fi enabled. Therefore, the MAC address broadcast by the Wi-Fi access point can be obtained. The terminal transmits the data (e.g., MAC address) that can identify the Wi-Fi access point to the location server via the wireless communication network. The location server obtains the geographical location of each Wi-Fi access point through search, calculates the geographical location of the terminal, and refers to the intensity of the Wi-Fi broadcast signal to transmit the geographical location to the positioning device 208 of the terminal.

[0083] The audio circuit 209, speaker 213, and microphone 214 can provide an audio interface between the user and the mobile phone 200. The audio circuit 209 can convert the received audio data into an electrical signal, and then transmit the electrical signal to the speaker 213. The speaker 213 can convert the electrical signal into an audio signal and output it. In addition, the microphone 214 can convert the captured audio signal into an electrical signal. The audio circuit 209 can convert the received electrical signal into audio data, and then output the audio data to the RF circuit 202. Then, the audio data is transmitted to another mobile phone or output to the memory 203 for further processing.

[0084] The peripheral device interface 210 is configured to provide various interfaces for external input / output devices (e.g., a keyboard, a mouse, a display externally connected to the mobile phone, an external memory, or a subscriber identification module card). For example, the terminal is connected to a mouse via a universal serial bus (USB) interface. By using the metal contacts on the card slot of a subscriber identification module (SIM) card provided by a telecommunications carrier, the terminal is connected to the subscriber identification module card. The peripheral device interface 210 may be configured to couple an external input / output peripheral device to the processor 201 and the memory 203.

[0085] The mobile phone 200 may further include a power supply device 211 (e.g., a battery and a power management chip) that supplies power to various components. The battery may be logically connected to the processor 201 by using a power management chip to perform functions such as charge management, discharge management, and power consumption management by using the power supply device 211.

[0086] Note that the solution in the present embodiment of this application may be further applied to another mobile terminal 101, and the corresponding name may also be replaced with the name of the corresponding function in the other mobile terminal 101.

[0087] Hereinafter, the satellite exploration method provided in the embodiment of this application will be described in detail with reference to FIG. 3.

[0088] For example, FIG. 3 is a schematic flowchart of a satellite exploration method according to an embodiment of this application. The satellite exploration method is applicable to the aforementioned mobile terminal 101, and the mobile terminal 101 is located in the aforementioned satellite exploration system. Referring to FIG. 3, the satellite exploration method includes the following steps.

[0089] S301. Based on the position information of the mobile terminal 101, the position information of the available satellite 102, and the three-dimensional 3D map information, determine whether the direct line of sight between the mobile terminal 101 and the available satellite 102 is blocked by an obstacle. If it is blocked, perform S302.

[0090] Specifically, the position information of the mobile terminal 101 may include, but is not limited to, the latitude and longitude information obtained from the available satellite 102, and the identification information of the base station used for communication by the mobile terminal 101 and obtained from the wireless network. The three-dimensional 3D map information may be obtained from pre-stored information, and the three-dimensional 3D map information includes the position, height, and shape contour of each obstacle on the 3D map. The position information of the satellite includes satellite operation parameters (orbital inclination angle, satellite distance from the ground, eccentricity, mean anomaly, etc.).

[0091] For the user's operation, the user can tap on the system home screen of the mobile terminal 101 to enter the home screen of the target application, and then tap on the "Start satellite search" touch key on the home screen to perform S301. The location information of the mobile terminal 101, the location information of the available satellites 102, and the three-dimensional (3D) map information may be obtained first. Specifically, the method of obtaining the location information of the mobile terminal 101 is not limited to these, but may be obtained based on the LBS service or based on the GPS positioning module. The method of obtaining the location information of the available satellites 102 is not limited to this, but may be to obtain the location information of the available satellites 102 from the pre-stored satellite ephemeris. Before the location information of the available satellites 102 is obtained, it should be noted that the available satellites 102 need to be determined from a plurality of satellites based on the location information of the mobile terminal 101, the satellite signal coverage, and the plurality of satellite operation parameters included in the pre-stored ephemeris information. The satellite operation parameters may further include the coverage area of each satellite transmission signal on the earth at different times and the signal strength of the coverage area.

[0092] In addition, the method of determining the available satellites 102 may be to select satellites whose coverage area includes the location information of the mobile terminal 101 and whose signal strength in the coverage area is greater than a preset threshold within a preset time at the current time and after the current time, and determine the satellites as the available satellites 102. When the location information of the mobile terminal 101, the location information of the available satellites 102, and the location, height, and shape contour of each obstacle on the 3D map are known, by using geometric relationships, it can be determined that the direct line of sight between the mobile terminal 101 and the available satellites 102 is blocked by obstacles. The obstacles may be dense vegetation, terrain uplifts due to geological movements, buildings, etc. This is not limited in this specification.

[0093] Specifically, as shown in FIG. 4, FIG. 4 includes a mobile terminal A, a mobile terminal B, a mobile terminal C, an obstacle a, an obstacle b, an obstacle c, and an obstacle d. The projected position of the available satellite 102 on the ground is point S. Details will be described later.

[0094] For example, the obstacle a is located on the connection line between the mobile terminal A and the point S. Therefore, the obstacle a may block the direct line of sight between the mobile terminal A and the available satellite 102. In this way, the height of the direct line of sight at the position of the obstacle a can be determined by using the principle of similar triangles based on the ratio of the distance from the obstacle a to the mobile terminal A, the distance from the mobile terminal A to the point S, and the distance between the available satellite 102 and the point S, and the height of the obstacle a is identified as higher than the height of the direct line of sight at the position of the obstacle a. In this way, it can be determined that the direct line of sight between the mobile terminal A and the available satellite 102 is blocked by the obstacle.

[0095] As another example, the obstacle d is located on the connection line between the mobile terminal C and the point S. Therefore, the obstacle d may block the direct line of sight between the mobile terminal C and the available satellite 102. The height of the direct line of sight at the position of the obstacle d can be determined by using the principle of similar triangles based on the ratio of the distance from the obstacle d to the mobile terminal C, the distance from the mobile terminal C to the point S, and the distance between the available satellite 102 and the point S, and the height of the obstacle d is identified as lower than the height of the direct line of sight at the position of the obstacle d. In this way, it can be determined that there is a direct line of sight between the mobile terminal C and the available satellite 102.

[0096] As another example, the obstacles b and c are not located on the connection line between the point S and any of the mobile terminals 101. Therefore, it can be directly determined that the obstacles b and c do not interfere with the direct line of sight between any of the mobile terminals and the available satellite 102.

[0097] S302: Determine the position information of the target area based on the 3D map information.

[0098] The target area is an area where there is a direct line of sight between the mobile terminal 101 and the available satellite 102. Since the position information of the available satellite 102 and the positions, heights, and shape contours of each obstacle in the 3D map are known, the area where there is a direct line of sight between the mobile terminal 101 and the available satellite 102 can be determined by using geometric relationships.

[0099] Furthermore, the target area may be an area where the distance from the mobile terminal 101 is less than or equal to a preset distance. Since the target area may be an area where the distance from the mobile terminal 101 is less than or equal to a preset distance, the time spent by the user to reach the target area from the location where the mobile terminal 101 is located is the shortest. This improves the user's operation experience.

[0100] Furthermore, in one possible design, the step of determining the position information of the target area based on the 3D map information in S302 may include the following:

[0101] Step A1: Determine the candidate area.

[0102] The candidate area may be an area where the distance from the mobile terminal 101 is less than or equal to a preset distance. Optionally, the candidate area may include a plurality of sub-areas.

[0103] Specifically, in order to obtain a candidate region including a plurality of sub-regions, a circular region or a regular polygon region centered on the position of the mobile terminal 101 and with a distance from the mobile terminal 101 less than a preset distance may be divided. For example, the candidate region may include three, four, eight, or nine sub-regions. This is not limited in this specification. As shown in FIG. 5, the candidate region is a circular region with a distance from the mobile terminal 101 less than a preset distance, and the circular region includes three sub-regions (i.e., sub-region Q1, sub-region Q2, and sub-region Q3).

[0104] Step A2: Determine a target region based on the position information of at least one sub-region, the position information of the available satellite 102, and the 3D map information.

[0105] The target region may be a sub-region among the plurality of sub-regions that has a direct line of sight to the available satellite 102.

[0106] Specifically, the target region may be determined in order (for example, from left to right or from top to bottom) based on the position information of the sub-region, the position information of the available satellite 102, and the 3D map information. As shown in FIG. 5, the region covered by the shaded part is the determined target region (i.e., sub-region Q1). The position information of the sub-region may be the position information of the geometric center of the sub-region. In addition, the method of determining the target region is to determine whether the direct line of sight between the sub-region and the available satellite 102 is blocked by an obstacle based on the position information of the sub-region, the position information of the available satellite 102, and the three-dimensional 3D map information, and when the direct line of sight is not blocked, determine the sub-region as the target region.

[0107] In one embodiment, when the first selected sub-region is determined as the target region, the target region will not be determined based on the position information of subsequent sub-regions, the position information of available satellites 102, and the 3D map information. If the first selected sub-region is not determined as the target region, the next sub-region is selected to determine whether the sub-region can be used as the target region until the selected sub-region is determined as the target region, and so on. Specifically, the candidate region includes four sub-regions, and it is assumed that the first sub-region is traversed sequentially. If the first sub-region is not determined as the target region, the second sub-region is traversed. If the second sub-region is determined as the target region, the traversal is stopped, and the second sub-region is used as the finally determined target region.

[0108] In another embodiment, regardless of whether the first selected sub-region is determined as the target region, whether the second selected sub-region is the target region is continuously determined based on the position information of the second selected sub-region, the position information of available satellites 102, and the 3D map information until the selected sub-region is determined as the target region and the sub-region closest to the position of the mobile terminal 101 among the sub-regions determined as the target region is selected as the final result, and so on. Specifically, the candidate region includes four sub-regions, and it is assumed that all sub-regions among the four regions are traversed sequentially. If the sub-region obtained by the second traversal and the sub-region obtained by the fourth traversal are determined as the target region, and the position of the sub-region obtained by the second traversal is closest to the position of the mobile terminal 101, the sub-region obtained by the second traversal is used as the finally determined target region.

[0109] Furthermore, in another possible design, the step of determining the position information of the target region based on the 3D map information in S302 may include the following:

[0110] Step B1: Based on the 3D map information, determine the first included angle between the first connection line and the second connection line.

[0111] The first connection line may be the connection line between the top of the obstacle and the available satellite 102, and the second connection line may be the connection line between the projection of the available satellite 102 on the ground and the mobile terminal 101. Step B2: Determine the target area.

[0112] The target area may be located on the extension line of the second connection line, and the area where the difference between the first included angle and the second included angle is greater than the included angle threshold. The second included angle may be the included angle between the third connection line and the extension line of the second connection line, and the third connection line may be the connection line between the available satellite 102 and the extension line of the second connection line.

[0113] The principles of Step B1 to Step B2 are described with reference to FIG. 6. As shown in FIG. 6, the projection of the available satellite 102 on the ground is point S, the connection line between point S and the mobile terminal 101A is the second connection line, the connection line between the obstacle a and the available satellite 102 is the first connection line, and the included angle between the first connection line and the second connection line is K1. It can be understood that the position of the first connection line at the intersection of the second connection line and the direct line of sight of the available satellite 102 is exactly blocked by the top of the obstacle a. Therefore, on the extension line of the second connection line, in addition, in the area where the difference between the first included angle and the second included angle is greater than the included angle threshold (on the extension line of the second connection line and away from the obstacle a), the direct line of sight between that area and the available satellite 102 is not blocked by the obstacle a. Therefore, the area located on the extension line of the second connection line and where the difference between the first included angle and the second included angle is greater than the included angle threshold is determined as the target area (for example, the thick line part in FIG. 6), and the included angle between the third connection line and the extension line of the second connection line is K2.

[0114] In one possible design, as shown in FIG. 3, after determining the position information of the target area based on the 3D map information in S302, the method may further include the following steps.

[0115] S303: Output navigation information.

[0116] The navigation information is used to move from the position corresponding to the position information of the mobile terminal 101 to the target area based on the 3D map information. The navigation information can clearly instruct the user on how to reach the target area from the position of the mobile terminal 101. The navigation information can be displayed on the display interface of the target application, played by the speaker of the mobile terminal 101, or displayed on the application display interface and broadcast by the speaker of the mobile terminal 101.

[0117] In one possible design, as shown in FIG. 3, after S303 that outputs navigation information, the method may further include the following.

[0118] S304: When the mobile terminal 101 is already within the target area, obtain the pose information of the mobile terminal 101.

[0119] Specifically, the user can hold the mobile terminal 101 to move to the target area based on the navigation information and obtain the position information of the mobile terminal 101 during the movement process. In this way, it can be determined whether the mobile terminal 101 is already within the target area. If the mobile terminal 101 is already within the target area, the pose information of the mobile terminal 101 is obtained. The pose information of the mobile terminal 101 may include the elevation angle and azimuth angle of the mobile terminal 101, as well as the polarization angle of the antenna.

[0120] S305. Determine the maximum gain direction angle of the antenna based on the antenna pattern of the antenna of the mobile terminal 101 and the pose information of the mobile terminal 101.

[0121] The antenna pattern of the antenna refers to the included angle of the antenna with respect to the vertical direction when the mobile terminal 101 is installed vertically along the long side.

[0122] S306: Based on the position information of the mobile terminal 101 and the position information of the available satellite 102, determine the target direction angle of the available satellite 102.

[0123] The target direction angle includes a target azimuth angle, a target elevation angle, and a target polarization angle. Specifically, the target direction angle may be the included angle between the X-axis of the preset terrestrial coordinate system and the connection line between the antenna and the projection of the satellite on the ground when the mobile terminal 101 is installed vertically along the long side. The target elevation angle may be the included angle between the connection line between the antenna and the projection of the satellite on the ground and the connection line between the mobile terminal 101 and the satellite when the mobile terminal 101 is installed vertically along the long side. The target elevation angle may also be the direction in which the electric field strength is formed when the antenna extends radially when the mobile terminal 101 is installed vertically along the long side and the antennas are arranged in the vertical direction.

[0124] S307: Determine the first pose adjustment parameter based on the difference between the maximum gain direction angle and the target direction angle.

[0125] For example, when the difference is (5 degrees, 10 degrees, or 20 degrees), the first pose adjustment parameter may be "turn 5 degrees forward, turn 10 degrees to the left, and turn 20 degrees downward".

[0126] S308: Output prompt information corresponding to the first pose adjustment parameter.

[0127] The prompt information is used to adjust so that the difference between the maximum gain direction angle and the target direction angle is equal to or less than the angular threshold. The user can adjust the pose of the mobile terminal 101 based on the output prompt information corresponding to the first pose adjustment parameter, which is simple and fast. In addition, the first pose adjustment parameter is determined with reference to the coefficient of the antenna pattern. Therefore, the reliability of the determined first pose adjustment parameter is also high. The angular threshold may be 2 degrees, 3 degrees, 5 degrees, etc. This is not limited in this specification.

[0128] In one possible design, the prompt information may include one or more of display information, pan-tilt-zoom control information, voice prompt information, or vibration prompt information. As shown in FIG. 7, the display information may be an adjustment direction guide (e.g., an arrow) and an adjustment amplitude (e.g., an adjustment angle). The pan-tilt-zoom control information may be an analog signal that carries the adjustment direction and the adjustment amplitude, and the analog signal that carries the adjustment direction and the adjustment amplitude is output to the pan-tilt-zoom control unit. The pan-tilt-zoom control unit may control a motor that drives a pan-tilt-zoom that transports the mobile terminal 101 to adjust the pose, based on the adjustment direction and the adjustment amplitude, to automatically adjust the pose of the mobile terminal 101. The voice prompt information may be "rotate 10 degrees clockwise", "swing 5 degrees upward", etc. The vibration prompt information may be to control the vibration motor of the mobile terminal 101 to vibrate in order to prompt the user to adjust the pose of the mobile terminal 101.

[0129] It should be noted that in the adjustment process, the output prompt information may be different when the adjustment direction is correct or incorrect. For example, when the adjustment is correct, the display information may become smaller or the color may change to green, and when the adjustment is incorrect, the adjustment error display information may become larger or the color may change to red. In another example, when the adjustment is correct, the vibration / amplitude frequency of the vibration motor becomes smaller, and when the adjustment is incorrect, the vibration / amplitude frequency of the vibration motor becomes larger.

[0130] In one possible design, as shown in FIG. 3, after the step of outputting prompt information corresponding to the first pose adjustment parameter at S308, the method may further include the following steps:

[0131] S309: When the difference between the maximum gain direction angle and the target direction angle is less than or equal to the angular threshold, establish a communication connection between the mobile terminal 101 and the available satellite 102.

[0132] After the communication connection is established, the mobile terminal 101 sends a communication request to the available satellite 102. After receiving the communication request, the available satellite 102 sends feedback information to the mobile terminal 101. Based on the feedback information, the mobile terminal 101 establishes a communication connection with the available satellite 102, and as a result, the mobile terminal 101 can send a communication signal to the available satellite 102 or receive a communication signal sent by the available satellite 102.

[0133] S310: When the signal strength of the signal transmitted by the available satellite 102 and received by the mobile terminal 101 is less than or equal to the strength threshold, determine the second pose adjustment parameter.

[0134] When the signal strength is less than or equal to the strength threshold, it indicates that the communication quality between the mobile terminal 101 and the available satellite 102 is insufficient and the pose of the mobile terminal 101 needs to be adjusted again. The second pose adjustment parameter is the parameter that needs to be adjusted again. Note that for the process of determining the second pose adjustment parameter, refer to S304 - S308. Details are not described again here.

[0135] S311: When the actual adjustment amount is greater than or equal to the preset adjustment amount, output the second prompt information.

[0136] The actual adjustment amount is counted once each time the first pose adjustment parameter or the second pose adjustment parameter is determined, and the second prompt information may be information indicating satellite search failure.

[0137] When the actual adjustment amount is greater than or equal to a preset adjustment amount, it is indicated that the signal strength of the received signal transmitted by the available satellite 102 cannot exceed the strength threshold by adjusting the pose of the mobile terminal 101 at the current position. Therefore, in order to prompt the user to change the position, information indicating satellite search failure can be output, and the user is prevented from continuously adjusting the pose of the mobile terminal 101 to search for satellites. This reduces power consumption.

[0138] Based on the satellite search method provided in FIG. 3, whether the direct line of sight between the mobile terminal and the available satellite is blocked by an obstacle is determined based on the position information of the mobile terminal, the position information of the available satellite, and the three-dimensional 3D map information. If the direct line of sight is blocked, the position information of the target area is determined based on the 3D map information. The target area is an area where there is a direct line of sight between the mobile terminal and the available satellite. In this way, the satellite search method is applicable to the mobile terminal, and there is no need to install the antenna outside the mobile terminal, nor does the antenna occupy a large space inside the mobile terminal. Therefore, the mobile terminal has low cost, small size, and low power consumption.

[0139] The foregoing has described in detail the satellite search method provided in the embodiments of the present application with reference to FIGS. 3 to 7. The following will describe in detail a satellite search device configured to perform the satellite search method provided in the embodiments of the present application with reference to FIGS. 8 and 9.

[0140] Referring to FIG. 8, an embodiment of the present application further provides a satellite search device 800 that can be applied to the mobile terminal 101. The mobile terminal 101 is located in the aforementioned satellite search system. It should be noted that the basic principle and technical effects of the satellite search device 800 provided in the present embodiment of the present application are the same as those of the aforementioned embodiments. For the sake of brief description, for parts not mentioned in this embodiment, please refer to the corresponding content of the aforementioned embodiments. The device 800 includes a determination unit 801 and an acquisition unit 802.

[0141] The determination unit 801 is configured to determine whether the direct line of sight between the mobile terminal 101 and the available satellite 102 is blocked by an obstacle based on the position information of the mobile terminal 101, the position information of the available satellite 102, and the three-dimensional (3D) map information.

[0142] The acquisition unit 802 is configured to acquire the position information of the target area based on the 3D map information when the direct line of sight is blocked by an obstacle. The target area is an area where there is a direct line of sight between the mobile terminal 101 and the available satellite 102.

[0143] Furthermore, the target area is an area where the distance from the mobile terminal 101 is less than or equal to a preset distance.

[0144] Furthermore, in one possible design, as shown in FIG. 8, the acquisition unit 802 is configured to determine a candidate area, which is an area where the distance from the mobile terminal 101 is less than or equal to a preset distance. The candidate area may include a plurality of sub-areas.

The target area is a sub-area among the plurality of sub-areas where there is a direct line of sight to the available satellite 102.

[0146] Furthermore, in another possible design, as shown in FIG. 8, the acquisition unit 802 is configured to determine a first included angle between a first connection line and a second connection line based on the 3D map information. The first connection line is the connection line between the top of the obstacle and the available satellite 102, and the second connection line is the connection line between the projection of the available satellite 102 on the ground and the mobile terminal 101.

[0147] The acquisition unit 802 is further configured to acquire the position information of the target area. The target area is located on the extension line of the second connection line and is an area where the difference between the first included angle and the second included angle is greater than the included angle threshold. The second included angle is the included angle between a third connection line and the extension line of the second connection line, and the third connection line is the connection line between the available satellite 102 and the top of the obstacle.

[0148] In one possible design, as shown in FIG. 8, the apparatus 800 may further include an output unit 803 configured to output navigation information. The navigation information is used to move from the position corresponding to the position information of the mobile terminal 101 to the target area based on the 3D map information.

[0149] In one possible design, as shown in FIG. 8, the acquisition unit 802 may be further configured to acquire the pose information of the mobile terminal 101 when the mobile terminal 101 is already within the target area.
