Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method and apparatus for identifying obscured cells. Background Technology

[0002] Currently, mobile networks have permeated all aspects of social life, profoundly changing people's communication, interaction, and even their entire lifestyles. With the rapid development of the mobile internet, new services and businesses are constantly emerging, mobile data traffic is exploding, and people have higher requirements for the signal quality of the mobile internet.

[0003] However, with urban development, the number of high-rise buildings in cities is increasing, and the obstruction of cell tower antennas is becoming more and more common. This prevents base stations from transmitting signals to distant areas, resulting in poor signal quality in the cells covered by the base station antennas, failing to cover a wider user base, and thus affecting user experience. Therefore, how to effectively identify obstructed cells is a problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides a method and apparatus for identifying obscured cells, which can effectively identify obscured cells, enabling operators to optimize the identified obscured cells in a targeted manner, thereby improving the efficiency of base stations and user experience.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a method for identifying an obstructed cell. The method includes: identifying a plurality of first terminals, wherein the first terminals are outdoor terminals in a first cell, and the signal between the first terminals and a first network device to which the first cell belongs is obstructed; identifying a plurality of second terminals, wherein the second terminals are terminals in the first cell, and the distance between the second terminals and the first network device is less than or equal to a first threshold; and determining the first cell as an obstructed cell if the proportion of the plurality of first terminals to the outdoor terminals in the first cell is greater than or equal to a second threshold, and the proportion of the plurality of second terminals to the terminals in the first cell is greater than or equal to a third threshold.

[0007] Based on the method provided in the first aspect above, multiple first terminals and multiple second terminals can be identified. When the proportion of the multiple first terminals among the outdoor terminals in the first cell is greater than or equal to a second threshold, and the proportion of the multiple second terminals among the terminals in the first cell is greater than or equal to a third threshold, the first cell is determined to be an obstructed cell. Here, the multiple first terminals are obstructed outdoor terminals in the first cell, and the multiple second terminals are near-field terminals close to the first network device. Therefore, the method provided in the first aspect above comprehensively considers both obstructed outdoor terminals and near-field terminals within the cell when determining obstructed cells, making the determined obstructed cells more accurate. Subsequently, operators can specifically optimize the identified obstructed cells to improve base station performance and user experience.

[0008] One possible implementation involves identifying multiple first terminals, including: identifying outdoor terminals in a first cell; obtaining the path loss of a first signal received by the outdoor terminals in the first cell, where the first signal is a signal sent by a first network device to the outdoor terminals in the first cell; and identifying the outdoor terminals in the first cell whose path loss is greater than or equal to a fourth threshold as first terminals.

[0009] Based on the above method, outdoor terminals in the first cell can be identified, and then the outdoor terminals with relatively large path loss in the first cell can be identified as the first terminal.

[0010] In one possible implementation, the path loss of the first signal received by the third terminal is the ratio of the total path loss of the first signal received by the third terminal to the distance from the third terminal to the first network device, wherein the third terminal is any outdoor terminal in the first cell.

[0011] Based on the above method, the path loss of the first signal received by any terminal in the first cell is defined as the average path loss per unit distance, which makes it easier to determine the first terminal and thus the blocked cell.

[0012] One possible implementation is that the signal strength of the satellite signal from the outdoor terminal in the first cell is greater than or equal to the fifth threshold.

[0013] Based on the above method, the outdoor terminal in the first cell can be determined according to the signal strength of the satellite signal of the terminal in the first cell.

[0014] Secondly, this application provides an apparatus for identifying obscured cells to implement the above-described method.

These modules, units, or means can be implemented in hardware, software, or by hardware executing corresponding software. The hardware or software includes one or more modules or units corresponding to the above-described functions.

[0015] Thirdly, this application provides an apparatus for identifying obscured cells, the apparatus comprising: a processor; the processor being coupled to a memory, and after reading instructions from the memory, executing the method described in the first aspect above according to the instructions.

[0016] Fourthly, this application provides a computer-readable storage medium storing instructions that, when executed on a computer, cause the computer to perform the methods described in the first aspect or any possible implementation thereof.

[0017] Fifthly, embodiments of this application provide a computer program product containing instructions that, when run on a computer, cause the computer to perform the methods described in the first aspect or any possible implementation thereof.

[0026] The method and apparatus for identifying obscured cells provided in this application will now be described in detail with reference to the accompanying drawings.

[0027] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0028] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0029] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0030] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] The method provided in this application can be used in various communication systems. For example, the communication system can be a long-term evolution (LTE) system, a 5th generation (5G) communication system (also known as a new radio (NR) communication system), a Wi-Fi system, a 3rd generation partnership project (3GPP) related communication system, a future evolution communication system (such as a 6th generation (6G) communication system), or a system integrating multiple systems, etc., without limitation. The following examples illustrate this. Figure 1 Taking the communication system 10 shown as an example, the method provided in the embodiments of this application will be described. Figure 1 This is merely an illustrative diagram and does not constitute a limitation on the applicable scenarios of the technical solutions provided in this application.

[0033] like Figure 1 The diagram shown is a schematic diagram of the architecture of the communication system 10 provided in an embodiment of this application. Figure 1 In this system, the communication system 10 may include a network device 102, a terminal 103 and a terminal 104 that can communicate with the network device 102. Optionally, the communication system 10 may also include a device 101 for identifying obscured cells.

[0034] The network device in this application embodiment, such as network device 102, can be any device with wireless transceiver capabilities. This includes, but is not limited to: evolved Node B (NodeB or eNB or e-NodeB) in LTE, base station (gNodeB or gNB) or transmission receiving point / transmission reception point (TRP) in NR, base stations evolved from 3GPP, access nodes in WiFi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. Multiple base stations can support networks using the same technology mentioned above, or they can support networks using different technologies mentioned above. A base station can contain one or more co-located or non-co-located TRPs. The network device can also be a radio controller in a cloud radio access network (CRAN) scenario. The network device can also be a centralized unit (CU) and / or a distributed unit (DU). The network device can also be a server, wearable device, machine communication device, or vehicle-mounted device, etc. The following explanation uses network devices as base stations as an example. These network devices can be the same type of base station or different types of base stations. Base stations can communicate directly with terminals, or they can communicate with terminals through relay stations.

[0035] The terminals in this application embodiment, such as terminals 103 and 104, are devices with wireless transceiver capabilities. A terminal can also be called a terminal device, which can be a user equipment (UE). A UE includes handheld devices, in-vehicle devices, wearable devices, or computing devices with wireless communication capabilities. For example, a UE can be a mobile phone, a tablet computer, or a computer with wireless transceiver capabilities. Terminal devices can also be virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in autonomous driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in smart cities, or wireless terminals in smart homes, etc.

[0036] exist Figure 1In this system, network devices can provide wireless access services to terminals. Specifically, each network device corresponds to a service coverage area, and terminals entering this area can communicate with the network device to receive the wireless access services provided by the network device. Optionally, the service coverage area may include one or more cells. For example, the service coverage area corresponding to network device 102 includes a first cell, and terminal 103 accesses network device 102 through the first cell, as do terminal 104.

[0037] The device for identifying obscured cells in this application embodiment, such as device 101 for identifying obscured cells, can be any device with computing and communication capabilities, such as a computer, server, or cloud server, and can be used to identify obscured cells.

[0038] exist Figure 1 In this context, the device 101 for identifying obscured cells is deployed independently. However, in specific applications, the function of the device 101 for identifying obscured cells can also be deployed on the network device 102. It should be understood that in this case, the communication system 10 may not include the device 101 for identifying obscured cells.

[0039] Figure 1 The communication system 10 shown is for illustrative purposes only and is not intended to limit the technical solutions of this application. Those skilled in the art should understand that in specific implementations, the communication system 10 may also include other devices, and the number of network devices and terminals can be determined according to specific needs without limitation.

[0040] The methods provided in the embodiments of this application will be described in detail below.

[0041] like Figure 2 As shown in the figure, a method for identifying an obscured cell is provided in an embodiment of this application. The method for identifying an obscured cell includes the following steps:

[0042] S201: The device for identifying the obscured cell identifies multiple first terminals.

[0043] In this embodiment of the application, the device for identifying the obscured cell can be... Figure 1 The device 101 or network equipment 102 in the communication system 10 shown for identifying obscured cells.

[0044] The first terminal is an outdoor terminal in the first cell, and the signal between the first terminal and the first network device to which the first cell belongs is blocked.

[0045] One possible implementation involves the device for identifying the obstructed cell identifying an outdoor terminal in the first cell, obtaining the path loss of the first signal received by the outdoor terminal in the first cell, and determining the outdoor terminal in the first cell whose path loss is greater than or equal to a fourth threshold as the first terminal.

[0046] Wherein, the signal strength of the satellite signal of the outdoor terminal in the first cell is greater than or equal to the fifth threshold. The first signal is the signal transmitted by the first network device to the outdoor terminal in the first cell. The path loss of the first signal received by the outdoor terminal in the first cell is the difference between the antenna output power value of the first network device and the power value received by the outdoor terminal in the first cell, which is the total path loss of the first signal received by the outdoor terminal in the first cell; or, the path loss of the first signal received by the third terminal is the ratio of the total path loss of the first signal received by the third terminal to the distance from the third terminal to the first network device, which is the average path loss of the first signal received by the third terminal. Wherein, the third terminal is any outdoor terminal in the first cell, and the total path loss of the first signal received by the third terminal is the difference between the antenna output power value of the first network device and the power value received by the third terminal.

[0047] Understandably, the fourth and fifth thresholds mentioned above can be set according to actual needs. For example, the fourth threshold could be 1.8 dB / m, and the fifth threshold could be 40.

[0048] For example, taking communication system 10 as an example, terminal 103 in the first cell detects a satellite signal strength of 60. Terminal 103 in the first cell can send the detected satellite signal strength to device 101 for identifying obstructed cells. Device 101 for identifying obstructed cells determines that the satellite signal strength is greater than a fifth threshold (e.g., 40), and therefore identifies terminal 103 in the first cell as an outdoor terminal in the first cell. Then, terminal 103 determines that the average path loss of the first signal received by terminal 103 is 2.5 dB / m, and sends this path loss to device 101 for identifying obstructed cells. Device 101 for identifying obstructed cells determines that the path loss is greater than a fourth threshold (e.g., 1.8 dB / m), and therefore identifies terminal 103 as the first terminal.

[0049] Based on the above method, the device for identifying obstructed cells can identify multiple first terminals. These multiple first terminals are both outdoor terminals and terminals with significant path loss. Therefore, it can be determined that the signal between multiple first terminals and the first network device in the first cell is obstructed, and these multiple first terminals are obstructed outdoor terminals within the first cell. It should be understood that the above example is only an example of the device for identifying obstructed cells identifying one first terminal within one evaluation period. The calculation method for identifying multiple first terminals within one evaluation period is similar, so the above process can be referred to, and will not be elaborated further.

[0050] S202: The device for identifying obscured cells identifies multiple second terminals.

[0051] The second terminal is a terminal in the first cell, and the distance between the second terminal and the first network device is less than or equal to the first threshold.

[0052] Understandably, a terminal in the first cell can send the distance between itself and the first network device to the device identifying the obstructed cell. The device identifying the obstructed cell determines the terminal in the first cell whose distance to the first network device is less than or equal to a first threshold as the second terminal.

[0053] The distance between the terminal in the first cell and the first network device is calculated by the terminal in the first cell using Time Advance (TA).

[0054] One possible design is that the distance between a terminal in the first cell and the first network device is proportional to the TA measured by the terminal in the first cell.

[0055] For example, if the first cell occupies 20 MHz bandwidth, the subcarrier spacing is 15 kHz, the timing advance (TA) adjustment is 16 TS (sampling time) (i.e., 0.5208 μs), and the timing advance measured by the terminal in the first cell is 1 TA, then the one-way trip delay corresponding to one TA adjustment unit is 0.5208 * 3 * 10. 8 / 2 = 78.12 meters, meaning the distance between the terminal in the first cell and the first network device is 78.12 meters.

[0056] One possible design is that the first threshold can be set according to actual needs. For example, the first threshold could be 100 meters.

[0057] For example, taking communication system 10 as an example, the distance between terminal 103 and first network device 102 in the first cell is 80 meters, and the distance between terminal 104 and first network device 102 in the first cell is 70 meters. The device 101 for identifying the obscured cell determines that the distance between terminal 103 and terminal 104 in the first cell and the first network device is less than a first threshold, so terminal 103 and terminal 104 are identified as second terminals.

[0058] Based on the above method, the device for identifying obstructed cells can identify multiple second terminals. These second terminals are located at a distance less than or equal to a first threshold from the first network device, meaning they are clustered close to the first network device; in other words, they are near-field terminals. This indicates that the signal from the first network device cannot reach terminals further away, thus suggesting that the first cell containing these second terminals is obstructed, meaning the forward space of the first cell antenna is blocked.

[0059] Understandably, the process of identifying multiple first terminals and multiple second terminals by the aforementioned device for identifying obscured cells can be performed periodically. If a terminal in a cell performs n evaluation cycles within a set time period, then that terminal generates n results within that set time period. In other words, that terminal can be identified as a first terminal or a second terminal multiple times.

[0060] S203: If the proportion of multiple first terminals to outdoor terminals in the first cell is greater than or equal to a second threshold, and the proportion of multiple second terminals to terminals in the first cell is greater than or equal to a third threshold, the device for identifying the obscured cell determines the first cell as an obscured cell.

[0061] In this context, "terminals in the first cell" refers to all terminals in the first cell, and "outdoor terminals in the first cell" refers to all outdoor terminals in the first cell. Alternatively, "terminals in the first cell" refers to a subset of terminals in the first cell, and "outdoor terminals in the first cell" refers to all outdoor terminals within that subset.

[0062] One possible design is that the second and third thresholds mentioned above can be set according to actual needs. For example, the second threshold could be 80%, and the third threshold could be 70%.

[0063] The following section uses the first cell as an example to explain the specific process by which the device for identifying obscured cells determines the obscured cell.

[0064] For example, taking an evaluation period of 7 days as an example. Terminal 104 in the first cell detects a satellite signal strength of 50, and the average path loss per unit distance for outdoor terminal 104 in the first cell is 2.2 dB / m. Terminal 104 in the first cell sends its detected satellite signal strength and the average path loss to the device 101 for identifying obstructed cells. The device 101 for identifying obstructed cells determines that the satellite signal strength is greater than a fifth threshold (e.g., 40) and the path loss is greater than a fourth threshold (e.g., 1.8 dB / m), so terminal 104 is identified as the first terminal, i.e., the obstructed outdoor terminal. Thus, the spatial straight-line path between terminal 104 in the first cell and the antenna of the first cell is obstructed. Within 7 days, the proportion of multiple first terminals in the first cell to outdoor terminals in the first cell is 95%, and the device 101 for identifying obstructed cells determines that the proportion of multiple first terminals in the first cell to outdoor terminals in the first cell is greater than a second threshold (e.g., 80%). Within 7 days, if the proportion of multiple second terminals in the first cell to the total number of terminals in the first cell is 90%, the device 101 for identifying the obscured cell determines that the proportion of multiple second terminals to the total number of terminals in the first cell is greater than or equal to a third threshold (e.g., 70%). Therefore, the device 101 for identifying the obscured cell identifies the first cell as an obscured cell.

[0065] based on Figure 2 The method shown identifies a first cell as an obstructed cell using a device. Multiple first terminals are obstructed outdoor terminals within the first cell, and multiple second terminals are near-field terminals close to the first network device. Therefore, when identifying an obstructed cell, the device comprehensively considers both obstructed outdoor terminals and near-field terminals within the cell, resulting in a more accurate identification of obstructed cells. Subsequently, operators can optimize the identified obstructed cells to improve base station performance and user experience.

[0066] This application embodiment can divide the device for identifying obscured cells into functional modules or functional units based on the above method example. For example, each function can be divided into its own functional modules or functional units, or two or more functions can be integrated into one module. The integrated module can be implemented in hardware or as a software functional module or functional unit. The module or unit division in this application embodiment is illustrative and represents only one logical functional division; other division methods may be used in actual implementation.

[0067] like Figure 3 The diagram shown is a structural schematic of a device 30 for identifying obscured cells provided in an embodiment of this application. The device includes an identification module 301 and a processing module 302.

[0068] The identification module 301 is used to identify multiple first terminals, where each first terminal is an outdoor terminal in a first cell, and the signal between the first terminal and the first network device to which the first cell belongs is blocked. For example, the identification module 301 is used to execute the above-described S201.

[0069] The identification module 301 is also used to identify multiple second terminals, wherein the second terminals are terminals in the first cell, and the distance between the second terminals and the first network device is less than or equal to a first threshold; the identification module 301 is used to perform the above S202.

[0070] Processing module 302 is configured to determine that the first cell is an obstructed cell if the proportion of multiple first terminals to outdoor terminals in the first cell is greater than or equal to a second threshold, and the proportion of multiple second terminals to terminals in the first cell is greater than or equal to a third threshold. For example, processing module 302 is configured to execute the above-described S203.

[0071] One possible implementation is that the identification module 301 is specifically used to identify outdoor terminals in the first cell. The identification module 301 is further specifically used to acquire the path loss of a first signal received by an outdoor terminal in the first cell, where the first signal is a signal sent by a first network device to an outdoor terminal in the first cell. The identification module 301 is also specifically used to determine the outdoor terminals in the first cell whose path loss is greater than or equal to a fourth threshold as the first terminal.

[0072] One possible implementation is that the path loss of the first signal received by the third terminal is the ratio of the total path loss of the first signal received by the third terminal to the distance from the third terminal to the first network device, and the third terminal is any outdoor terminal in the first cell.

[0073] One possible implementation is that the signal strength of the satellite signal from the outdoor terminal in the first cell is greater than or equal to the fifth threshold.

[0074] Understandably, the aforementioned device for identifying obscured cells can also be implemented in hardware. For example, in hardware implementation, the identification module 301 in this embodiment can be integrated on the communication interface, and the processing module 302 can be integrated on the processor. As another example, in hardware implementation, both the identification module 301 and the processing module 302 in this embodiment are integrated on the processor. The hardware structure can be as follows... Figure 4 As shown.
