Those skilled in the art can understand that the terms "first" and "second" are not intended to limit the quantity or execution order.

[0027] As described in the background section, with the development of mobile communication technology, accurately determining the received power (also known as radio signal strength) of a terminal in a detection area can provide an important basis for network planning in that area. Currently, the method for determining the received power of a terminal in a detection area is usually the ray tracing method. However, the ray tracing method is typically applied to open environments (such as large stadiums). When the detection area is a complex environment (such as mountainous areas), the efficiency of the ray tracing method in determining the received power is relatively low.

[0028] To address the aforementioned problems, this application provides a method for determining received power. After acquiring the location information of the signal transmitting device and the location information of the area to be detected, since the location information of the area to be detected includes the location information of the sample detection point and the location information of the target detection point, the location information of the visible elements relative to the area to be detected can be determined based on the location information of the signal transmitting device and the location information of the sample detection point. Next, the received power of the sample detection point can be acquired, and then the received power of the target detection point can be determined based on the location information of the signal transmitting device, the location information of the visible elements, the location information of the target detection point, and the received power of the sample detection point.

[0029] As can be seen from the above, the method for determining the received power provided in this application embodiment can first determine the position information of visible elements relative to the area to be detected based on the position information of the signal transmitting device and the position information of the sample detection point. Since the distance between each detection point (e.g., the sample detection point and the target detection point) in the area to be detected is relatively short, the visible element relative to the area to be detected can be equivalent to the visible element of any detection point in the area to be detected. Therefore, when determining the received power of the target detection point, the already determined position information of the visible element can be used directly, without having to repeatedly determine the position information of the visible element of the target detection point, thus reducing the computational complexity of determining the received power and improving the efficiency of determining the received power.

[0030] This method for determining received power is applicable to systems that determine received power. Figure 1 One structure of the system for determining the received power is shown.

[0032] In practical applications, electronic device 101 can typically connect to multiple signal transmitting devices, and each signal transmitting device can connect to multiple signal detection devices. For ease of understanding, this application uses an electronic device 101 connected to a signal transmitting device 102, and a signal transmitting device 102 connected to a signal detection device 103.

[0033] Optionally, the signal detection device 103 can be deployed at the location corresponding to the sample detection point.

[0034] Optionally, the physical device of electronic device 101 can be a terminal, a server, or other types of electronic devices.

[0035] Optionally, the physical device of the signal detection device 103 can be a terminal or other devices used for signal detection.

[0036] Optionally, when the physical devices of electronic device 101 and signal detection device 103 are terminals, the terminal can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The terminal can communicate with one or more core networks via a radio access network (RAN). The terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network, such as a mobile phone, tablet computer, laptop computer, netbook, or personal digital assistant (PDA).

[0037] Optionally, when the physical device of electronic device 101 is a server, the server can be one of the servers in a server cluster (composed of multiple servers), a chip in the server, a system-on-a-chip in the server, or a virtual machine (VM) deployed on a physical machine. This application embodiment does not limit this.

[0038] Optionally, the signal transmitting device 102 can be a wireless communication base station or base station controller, etc. In this embodiment, the base station can be a base station (BTS) in Global System for Mobile Communication (GSM), a base station (node ​​B) in Code Division Multiple Access (CDMA), a base station (eNB) in the Internet of Things (IoT) or Narrow Band Internet of Things (NB-IoT), a base station in a future 5G mobile communication network or a future evolved public land mobile network (PLMN). This embodiment does not impose any limitations on this. The basic hardware structure of the electronic device 101 in the system for determining the received power is similar, all including... Figure 2 or Figure 3 The components included in the device for determining the received power are shown below. Figure 2 and Figure 3 Taking the device for determining the received power as an example, the hardware structure of electronic device 101 will be introduced.

[0039] like Figure 2 The diagram shown is a hardware structure schematic of a receiving power determination device provided in an embodiment of this application. The receiving power determination device includes a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, memory 22, and communication interface 23 are connected via the bus 24.

[0040] Processor 21 is the control center of the receiving power determination device. It can be a single processor or a collective term for multiple processing elements. For example, processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processors. Among them, the general-purpose processor can be a microprocessor or any conventional processor.

[0041] As one embodiment, processor 21 may include one or more CPUs, for example Figure 2 CPU 0 and CPU 1 are shown in the diagram.

[0042] The memory 22 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), disk storage media or other magnetic storage devices, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer, but is not limited thereto.

[0043] In one possible implementation, the memory 22 can exist independently of the processor 21. The memory 22 can be connected to the processor 21 via a bus 24 and is used to store instructions or program code. When the processor 21 calls and executes the instructions or program code stored in the memory 22, it can implement the method for determining the received power provided in the following embodiments of this application.

[0044] In this embodiment, the software programs stored in the memory 22 of the electronic device 101 are different, so the functions implemented by the electronic device 101 are different. The functions performed by each device will be described with reference to the following flowchart.

[0045] In another possible implementation, the memory 22 can also be integrated with the processor 21.

[0046] Communication interface 23 is used for the power receiving determination device to connect with other devices via a communication network, such as Ethernet, wireless access network, wireless local area network (WLAN), etc. Communication interface 23 may include a receiving unit for receiving data and a transmitting unit for transmitting data.

[0047] Bus 24 can be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industry standard architecture (EISA) bus, etc. This bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 2 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0048] Figure 3 Another hardware structure of the receiving power determination device in the embodiments of this application is shown. For example... Figure 3 As shown, the receiving power determination device may include a processor 31 and a communication interface 32. The processor 31 is coupled to the communication interface 32.

[0049] The functions of processor 31 can be referred to in the description of processor 21 above. In addition, processor 31 also has a storage function, and can perform the functions of memory 22 mentioned above.

[0050] The communication interface 32 is used to provide data to the processor 31. The communication interface 32 can be an internal interface of the receiving power determination device, or it can be an external interface of the receiving power determination device (equivalent to communication interface 23).

[0051] It should be pointed out that, Figure 2 (or Figure 3 The structure shown in the diagram does not constitute a limitation on the device for determining the received power, except... Figure 2 (or Figure 3 In addition to the components shown in the figure, the means for determining the received power may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0052] The method for determining the received power provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0053] like Figure 4 As shown, the method for determining the received power provided in this application embodiment is applied to an electronic device, and the method for determining the received power includes: S401-S404.

[0054] S401. The electronic device acquires the location information of the signal transmitting device and the location information of the area to be detected.

[0055] The location information of the area to be detected includes the location information of the sample detection points and the location information of the target detection points.

[0056] Optionally, one way for the electronic device to acquire the location information of the signal transmitting device and the location information of the area to be detected is as follows: The electronic device can acquire terrain data of a preset area. This preset area may include the signal transmitting device and the area to be detected. Then, the electronic device can model the terrain data to obtain three-dimensional data of the preset area. This three-dimensional data may include the location information of the signal transmitting device and the location information of the area to be detected.

[0057] Since the 3D data is composed of multiple triangular facets, the region to be detected can be any one of the triangular facets in the preset region. In this case, the location information of the region to be detected can be the location determined by the spatial coordinates of the three endpoints of the triangular facet corresponding to the region to be detected. The sample detection point and the target detection point can be any two points in the triangular facet corresponding to the region to be detected (for example, the sample detection point can be an endpoint of the triangular facet corresponding to the region to be detected, and the target detection point can be any point in the triangular facet corresponding to the region to be detected). The location information of the signal transmitting device can be the spatial coordinates of the signal transmitting device in the 3D data of the preset region mentioned above.

[0058] Alternatively, another way for the electronic device to acquire the location information of the signal transmitting device and the location information of the area to be detected is as follows: A surveyor can manually measure the location information of the signal transmitting device and the area to be detected using a surveying instrument (e.g., a topographic detector). Then, the surveyor can input the measured location information of the signal transmitting device and the area to be detected onto the electronic device. Accordingly, the electronic device, in response to the operation performed by the surveyor, acquires the location information of the signal transmitting device and the area to be detected.

[0059] S402. The electronic device determines the position information of the visible elements relative to the area to be detected based on the position information of the signal transmitting device and the position information of the sample detection point.

[0060] Specifically, during the propagation of a signal emitted by a signal transmitting device, the signal may be reflected at the location of an obstacle due to obstruction. In this case, the surface element corresponding to the location of the obstacle (i.e., the reflection point) is the visible surface element relative to the area to be detected. Since the signal attenuation is high when the number of reflections exceeds a preset number, when determining the visible surface elements, usually only the surface elements corresponding to the reflection points of signal propagation paths with a number of reflections less than or equal to the preset number are determined.

[0061] For example, when the preset number of times is 2, the visible surface element may include a first-order reflective surface element (i.e., the surface element where the reflection point of the signal propagation path with 1 reflection time is located) and a second-order reflective surface element (i.e., the surface element where the reflection point of the signal propagation path with 2 reflection times is located).

[0062] Optionally, the electronic device can use ray tracing to determine the position information of visible elements relative to the area to be detected, based on the position information of the signal transmitting device and the position information of the sample detection point.

[0063] Specifically, because the ray tracing method only needs the initial position information of the signal during propagation and the receiving position information during the signal propagation process to determine the position information of the reflection point in the preset area, electronic devices can use the ray tracing method to determine the reflection point corresponding to the propagation path of the signal with a reflection number of 1 and the reflection point corresponding to the propagation path of the signal with a reflection number of 2, based on the position information of the signal transmitting device (i.e., the initial position information of the signal during propagation) and the position information of the sample detection point (i.e., the receiving position information of the signal during propagation). Furthermore, based on the reflection point corresponding to the propagation path of the signal with a reflection number of 1 and the reflection point corresponding to the propagation path of the signal with a reflection number of 2, the position information of the first-order and second-order reflection surface elements relative to the sample detection point (i.e., the spatial coordinate points corresponding to the three endpoints of the first-order and second-order reflection surface elements) can be determined.

[0064] As shown above, since the distances between the detection points (e.g., sample detection points and target detection points) in the area to be detected are relatively short, the first-order and second-order reflective elements relative to the sample detection points can be equivalent to the visible elements relative to the area to be detected. Therefore, after the electronic device determines the position information of the first-order and second-order reflective elements relative to the sample detection points, it can equate this position information to the position information of the visible elements relative to the area to be detected.

[0065] S403, Electronic equipment acquires the receiving power of the sample detection point.

[0066] The received power can also be referred to as the radio signal strength at the sample detection point.

[0067] Specifically, when there are no obstacles during the propagation of the signal emitted by the signal transmitting device, the signal travels in a straight line to reach the sample detection point. In this case, the straight propagation path is called the direct path. Since the signal attenuation is lower on the direct path and the signal propagation path with fewer than or equal to a preset number of reflections, when determining the received power at the sample detection point, it is necessary to determine the received power of the direct path and the signal propagation path with fewer than or equal to a preset number of reflections relative to the sample detection point separately, and then sum the received power of the direct path and the signal propagation path with fewer than or equal to a preset number of reflections relative to the sample detection point to determine the received power of the sample detection point.

[0068] When determining the received power of a signal propagation path relative to the direct path and the number of reflections of a sample detection point less than or equal to a preset number, electronic devices need to first obtain relevant parameters of the base station and the sample receiving point. These parameters include: the transmit power of the signal transmitting device, the transmit gain of the signal transmitting device, the receive gain of the sample detection point, the wavelength of the signal, and the reflection coefficient.

[0069] Next, the electronic device can determine the receiving power of the signal propagation path with a direct path and a reflection number less than or equal to a preset number of times relative to the sample detection point, based on the length of the direct path and the signal propagation path with a reflection number less than or equal to a preset number of times, as well as the transmission power of the signal transmitting device, the transmission gain of the signal transmitting device, the receiving gain of the sample detection point, the wavelength of the signal, and the reflection coefficient.

[0070] For example, assuming the preset number of times is 2, when determining the received power of the sample detection point, the lengths of the direct path (i.e., the path along which the signal propagates in a straight line to the sample detection point), the first-order reflection path (i.e., the path of the signal propagation with 1 reflection time), and the second-order reflection path (i.e., the path of the signal propagation with 2 reflection times) relative to the sample detection point can be determined separately, as well as the transmission power of the signal transmitting device, the transmission gain of the signal transmitting device, the receiving gain of the sample detection point, the wavelength of the signal, and the reflection coefficient. The received power of the direct path relative to the sample detection point, the received power of the first-order reflection path relative to the sample detection point, and the received power of the second-order reflection path relative to the sample detection point can be determined separately. Then, the sum of the received power of the direct path relative to the sample detection point, the received power of the first-order reflection path relative to the sample detection point, and the received power of the second-order reflection path relative to the sample detection point is determined as the received power of the sample detection point.

[0071] S404. The electronic device determines the receiving power of the target detection point based on the location information of the signal transmitting device, the location information of the visible element, the location information of the target detection point, and the receiving power of the sample detection point.

[0072] Specifically, because the distances between multiple points in the area to be detected are relatively short, a visible element relative to the area to be detected can be equivalent to a visible element at any point in the area. Next, the electronic device can use the mirror method to determine the mirror point of the signal transmitting device relative to the visible element based on the position information of the signal transmitting device and the visible element. Then, the electronic device can determine the intersection of the line segment between the target detection point and the mirror point of the signal transmitting device relative to the visible element, and the visible element, as the first-order and second-order reflection points of the signal propagation path from the signal transmitting device to the target detection point.

[0080] S501. The electronic device acquires terrain data of the area to be detected and the preset area to which the signal transmitting device belongs.

[0081] The terrain data of the preset area includes the contour lines and slope data of the preset area.

[0082] Optionally, the method for electronic devices to acquire terrain data of the area to be detected and the preset area to which the signal transmitting device belongs may include: acquiring terrain data of the preset area using a global positioning system (GPS), measuring terrain data of the preset area based on aerial or space imagery, or manually measuring terrain data by surveyors using measuring instruments (such as terrain detectors).

[0083] S502. The electronic equipment models the acquired terrain data based on the regular grid model in the digital elevation model to obtain the three-dimensional data of the preset area.

[0084] The three-dimensional data includes the location information of the signal transmitting equipment and the location information of the area to be detected.

[0085] Optionally, one implementation method for the electronic device to model the acquired terrain data based on a regular grid model in a digital elevation model (DEM) to obtain 3D data of a preset area is as follows: The electronic device converts the acquired terrain data of the preset area into multiple 3D coordinate points. Based on these multiple 3D coordinate points, the electronic device performs 3D modeling of the terrain surface, transforming the complex real-world terrain into a regular grid model in the DEM composed of multiple continuous, interconnected triangular facets, thereby obtaining the 3D data of the preset area. In this case, the electronic device determines the positional information of the signal transmitting device and the positional information of the area to be detected within the preset area based on the positional relationship between the signal transmitting device, the area to be detected, and the 3D model of the preset area.

[0086] For example, after obtaining the three-dimensional data of the preset area, since the three-dimensional data is composed of multiple triangular facets, the area to be detected can be any triangular facet in the preset area whose received power needs to be predicted (also known as a sample triangular facet).

[0087] In this case, the coordinates of the signal transmitting device are ( , , ).

[0088] Assuming the region to be detected can be represented by triangular elements △ Sample detection points can include triangular facets △ endpoints Then the triangular element △ endpoints The coordinates are ( , , ).

[0089] Assuming the target detection point can include triangular facets △ any point in Then the triangular element △ any point in The coordinates are ( , , In one embodiment, combined with Figure 5 ,like Figure 6As shown, the method for the electronic device to obtain the received power of the sample detection point in S403 above specifically includes: S601-S602.

[0090] S601, Electronic equipment acquires the transmission power of the signal transmitting device, the transmission gain of the signal transmitting device, the receiving gain of the sample detection point, the length of the signal propagation path between the signal transmitting device and the sample detection point, the wavelength of the signal, and the reflection coefficient.

[0091] The transmission power of the signal transmitting equipment is the signal strength of the radio signal emitted by the signal transmitting equipment.

[0092] The transmit gain of the signal transmitting device is equal to the antenna gain of the signal transmitting device, and the receive gain of the sample detection point is equal to the antenna gain of the sample detection point. In this case, the antenna gain is the ratio of the power density of the signal generated by the actual antenna and the ideal radiating element at the same point in space, assuming equal power.

[0093] The wavelength is the distance between two particles whose displacement relative to the equilibrium position is the same at the same time as the signal's corresponding electromagnetic wave graph.

[0094] The reflection coefficient is the ratio between the portion of the signal reflected by the interface of the impedance discontinuity and the total electromagnetic wave.

[0095] In this embodiment, the reflection coefficient is divided into the reflection coefficient of the direct path, the reflection coefficient of the first-order reflection path, and the reflection coefficient of the second-order reflection path. When the signal propagation path is a direct path, the reflection coefficient is 1.

[0096] Optionally, the electronic device determines the length of the direct path from the signal transmitting device to the sample detection point based on the location information of the signal transmitting device and the location information of the sample detection point.

[0097] The electronic device determines the length of the first-order reflection path from the signal transmitting device to the sample detection point based on the location information of the signal transmitting device, the location information of the first-order reflection point, and the location information of the sample detection point.

[0098] The electronic device determines the length of the second-order reflection path from the signal transmitting device to the sample detection point based on the location information of the signal transmitting device, the location information of the second-order reflection point, and the location information of the sample detection point.

[0099] S602. The electronic device determines the receiving power of the sample detection point based on the transmitting power of the signal transmitting device, the transmitting gain of the signal transmitting device, the receiving gain of the sample detection point, the length of the signal propagation path between the signal transmitting device and the sample detection point, the wavelength of the signal, and the reflection coefficient.

[0100] The received power at the sample detection point satisfies the following formula: ; Used to indicate the transmission power of a signal transmitting device. Used to indicate the transmit gain of a signal transmitting device. Used to represent the receiver gain of the sample detection point Used to represent the length of the signal propagation path between the signal transmitting device and the sample detection point. The wavelength of the signal is used to represent the wavelength, and R is used to represent the reflection coefficient. Used to indicate the received power at the sample detection point.

[0101] For example, in combination Figure 1 The signal transmitting device 102 has a transmitting power of 100 dB / mW, and both the transmitting gain of the signal transmitting device 102 and the receiving gain of the signal detection device 103 (i.e., the sample detection point) are 10. The wavelength of the signal is 10 meters, and the direct distance between the signal transmitting device 102 and the signal detection device 103 is 50 meters. In this case, the receiving power of the sample detection point is... =(100 100 10 10) ÷ 394375 = 2.54 dBmW.

[0102] In one embodiment, combined with Figure 6 ,like Figure 7 As shown, in S404 above, the method by which the electronic device determines the receiving power of the target detection point based on the location information of the signal transmitting device, the location information of the visible element, and the receiving power of the sample detection point specifically includes: S701-S704.

[0103] S701. The electronic device determines the signal propagation path from the signal transmitting device to the target detection point based on the location information of the signal transmitting device, the location information of the visible element, and the location information of the target detection point.

[0104] Optionally, one implementation of the electronic device determining the signal propagation path from the signal transmitting device to the target detection point based on the location information of the signal transmitting device and the visible element is as follows: The electronic device determines the mirror image point of the signal transmitting device relative to the visible element based on the location information of the signal transmitting device and the visible element. Then, the electronic device can determine the intersection point of the line segment between the target detection point and the mirror image point of the signal transmitting device relative to the visible element, and the visible element, as the first-order reflection point and second-order reflection point of the signal propagation path from the signal transmitting device to the target detection point.

[0105] Next, the electronic device determines the direct path relative to the target detection point based on the location information of the signal transmitting device and the location information of the target detection point.

[0106] The electronic device determines the first-order reflection path for the target detection point based on the location information of the signal transmitting device, the location information of the target detection point, and the location information of the first-order reflection point of the signal propagation path from the signal transmitting device to the target detection point.

[0107] The electronic device determines the second-order reflection path for the target detection point based on the location information of the signal transmitting device, the location information of the target detection point, and the location information of the second-order reflection point of the signal propagation path from the signal transmitting device to the target detection point.

[0108] S702. When the signal direction received by the target detection point makes an acute angle with the normal vector of the plane where the area to be detected is located, the electronic device determines the signal propagation path corresponding to the signal direction as the effective propagation path.

[0109] The direction of the signal received by the target detection point is the direction of the visible signal propagation path from the signal transmitting device to the target detection point.

[0110] Optionally, the electronic device determines the spatial vectors corresponding to the direct path, first-order reflection path, and second-order reflection path from the signal transmitting device to the target detection point, as well as the normal vector of the plane containing the area to be detected, based on the mirror position information of the signal transmitting device relative to the visible surface and the position information of the visible surface. In this case, the electronic device can determine the angle between the two vectors.

[0111] Since the above propagation path is blocked by the terrain during the actual signal propagation process when the included angle is greater than or equal to 90°, it cannot be received by the target detection point. Therefore, when determining the received power of the target detection point, only the sum of the received power of the effective propagation path needs to be calculated.

[0112] When the included angle is greater than or equal to 0° and less than 90°, the electronic device determines the above signal propagation path as a valid propagation path.

[0113] When the included angle is greater than or equal to 90°, the electronic device determines that the above signal propagation path is an invalid propagation path.

[0114] S703, The length of the effective propagation path of the signal from the signal transmitting device to the target detection point is acquired by the electronic equipment.

[0115] Optionally, the electronic device determines the mirror position coordinates of the signal transmitting device relative to the visible surface based on the signal propagation path between the signal transmitting device and the target detection point. Using the distance formula between the two points, the electronic device determines the length of the signal propagation path between the signal transmitting device and the target detection point based on the mirror position coordinates of the signal transmitting device relative to the visible surface and the coordinates of the target detection point.

[0116] S704. The electronic device determines the receiving power of the target detection point based on the length of the signal propagation path between the signal transmitting device and the sample detection point, the receiving power of the sample detection point, and the length of the effective signal propagation path from the signal transmitting device to the target detection point.

[0117] The received power at the target detection point satisfies the following formula: ; Used to represent the received power at the sample detection point Used to represent the length of the signal propagation path between the signal transmitting device and the sample detection point. Used to represent the length of the effective signal propagation path from the signal transmitting device to the target detection point. Used to represent the received power of the target detection point. For example, combined with... Figure 1 The receiving power of signal detection device 103 is 10 dBmW, the length of the signal propagation path between signal transmitting device 102 and signal detection device 103 is 10 meters, and the length of the effective signal propagation path from the signal transmitting device to the target detection point is 12 meters. In this case, the receiving power of the target detection point = 10 dBmW. 100 ÷ 144 = 6.94 dBmW.

[0118] Optionally, since the target detection point may receive signals from multiple directions, there can be multiple effective propagation paths for the signal at the target detection point. The calculation method for the received power of multiple effective propagation paths is the same as the calculation method for the received power of a single effective propagation path. The sum of the received power of multiple effective propagation paths of the target detection point is determined as the received power of the target detection point.
