Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, equipment, medium and program product for identifying underground parking lots. Background Technology

[0002] With the increasing popularity of new energy vehicles, daily needs such as QR code charging and mobile payments in underground parking garages urgently require stable network support. Currently, identifying underground parking lots typically relies on latitude and longitude data reported by users.

[0003] However, in the above methods, in underground environments, due to severe signal obstruction, the latitude and longitude data reported by users can have errors of tens or even hundreds of meters, which may result in "location drift" and make it impossible to accurately determine whether the community contains an underground parking lot. Summary of the Invention

[0045] The following is a detailed description of the underground parking lot identification method, device, equipment, medium, and program products provided in this application, with reference to the accompanying drawings.

[0046] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0047] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0048] The terms "at least one," "at least one of," etc., used in the specification and claims of this application refer to any one, any two, or a combination of two or more of the included items. For example, at least one of a, b, and c can mean: "a," "b," "c," "a and b," "a and c," "b and c," and "a, b, and c," where a, b, and c can be single or multiple. Similarly, "at least two" refers to two or more items, and its meaning is similar to that of "at least one."

[0049] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0050] The embodiments of this application provide an underground parking lot identification method, device, equipment, medium, and program product, which can be applied to scenarios of identifying whether a community contains an underground parking lot, and if so, what type of underground parking lot it is.

[0051] With the increasing popularity of new energy vehicles, daily needs such as QR code charging and mobile payments in underground parking garages urgently require stable network support. Furthermore, by identifying underground parking lots, operators can shift from "passively handling complaints" to "proactively and precisely building networks." This not only avoids blind investment but also enhances user stickiness by creating a high-quality vehicle-to-everything (V2X) and digital ecosystem experience, allowing them to seize a strategic advantage in the fierce market competition. Meanwhile, the Ministry of Industry and Information Technology and other departments are comprehensively promoting the "signal upgrade" campaign, explicitly requiring a focus on resolving the weak coverage issues in enclosed spaces such as underground parking lots and elevators. Therefore, proactively identifying underground parking lots is a problem that operators urgently need to address.

[0052] Currently, identifying underground parking lots typically relies on latitude and longitude data reported by users. However, on the one hand, 5G network users almost never report latitude and longitude data; on the other hand, in underground environments, due to severe signal obstruction, the latitude and longitude data reported by users can have errors of tens or even hundreds of meters, frequently resulting in "location drift." This makes it impossible to accurately determine whether a residential area contains an underground parking lot.

[0053] To address the aforementioned technical problems, this application provides an underground parking lot identification method, apparatus, device, medium, and program product. The underground parking lot identification apparatus can acquire vehicle-mounted MR data reported by at least one vehicle in a target area within a target time period. Based on the reporting time and received signal strength included in the vehicle-mounted MR data, it determines whether the target area contains an underground parking lot without coverage; or based on the cell type corresponding to the cell identifier included in the vehicle-mounted MR data, it determines whether the target area contains a covered underground parking lot. That is, the underground parking lot identification apparatus can not only determine whether the target area contains an underground parking lot, but also, based on this, determine whether the target underground parking lot is an underground parking lot without coverage or a covered underground parking lot, and can determine the network coverage status of the underground parking lot. Then, based on the acquired latitude and longitude data, the underground parking lot identification apparatus can further determine the specific location information of the target underground parking lot, thus improving the accuracy of underground parking lot identification.

[0054] The following description, in conjunction with the accompanying drawings, details the underground parking lot identification method, apparatus, equipment, medium, and program products provided in the embodiments of this application.

[0055] Figure 1 The network architecture of an underground parking lot identification method provided in an embodiment of this application is illustrated. For example... Figure 1 As shown, the network architecture includes an underground parking lot identification device 101 and a terminal device 102. The underground parking lot identification device 101 and the terminal device 102 are interconnected.

[0056] In some embodiments, the underground parking lot identification device 101 may be a server, a computer, or a processor or processing unit within a server or computer. The server may be a single server or a server cluster consisting of multiple servers. It should be noted that this application does not limit the specific device form of the underground parking lot identification device 101. Figure 1 The underground parking lot identification device 101 is used as an example of a single server.

[0057] In some embodiments, the terminal device may be a mobile phone, tablet computer, laptop computer, handheld computer, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, personal computer (PC), ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc., and the embodiments of this application do not specifically limit it. Figure 1 The example shown is a vehicle-mounted electronic device, with terminal device 102 as an example.

[0058] In some embodiments, the underground parking lot identification device 101 can acquire vehicle-mounted MR data reported by at least one terminal device 102 in the target area within a target time period. The vehicle-mounted MR data includes: cell identifier, received signal strength, reporting time, and latitude and longitude data. Therefore, if the reporting time and received signal strength meet a first determination condition, the underground parking lot identification device 101 can determine that the target area includes an underground parking lot without coverage. If the cell type determined based on the cell identifier meets a second determination condition, the underground parking lot identification device 101 can determine that the target area includes an underground parking lot with coverage. Further, the underground parking lot identification device 101 can determine the location information of the underground parking lot without coverage or the underground parking lot with coverage in the target area based on the latitude and longitude data.

[0059] It should be noted that the network architecture described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As network architectures evolve, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0060] See Figure 2 This is a flowchart illustrating an underground parking lot identification method provided in an embodiment of this application. Figure 2 As shown, the underground parking lot identification method provided in this application embodiment can be implemented by the above-mentioned underground parking lot identification device, specifically including the following steps 201 to 204.

[0061] Step 201: The underground parking lot identification device acquires the vehicle MR data reported by at least one vehicle in the target area within the target time period.

[0062] In some embodiments, the target time period can be a preset underground parking lot identification cycle.

[0063] It is understood that the underground parking lot identification device can periodically acquire vehicle-mounted MR data based on the target time period in order to execute the underground parking lot identification method provided in the embodiments of this application.

[0064] It should be noted that the duration of the aforementioned target time period can be set according to actual needs, and this embodiment of the application does not impose any limitation on it.

[0065] It should be noted that the area of ​​the target region mentioned above can be determined according to actual needs, and this embodiment of the application does not limit it here.

[0066] In some embodiments, the underground parking lot identification device can acquire all periodically reported Measurement Report (MR) data in the target area, and further determine the on-board MR data reported by at least one vehicle based on the operator's vehicle card trajectory table.

[0067] It should be noted that the above-mentioned basic MR data can be a set of quantitative measurements of the wireless environment continuously reported to the base station by mobile terminals (such as mobile phones and in-vehicle electronic devices) at fixed time intervals (usually 5s, 10s, etc.).

[0068] In some embodiments, the aforementioned basic MR data may include, but is not limited to, at least one of the following: user identifier, reporting time, cell information, reference signal received power (RSRP), reference signal received quality (RSRQ), uplink signal to interference plus noise ratio (SINR), and timing advance (TA) of the serving cell and multiple neighboring cells.

[0069] It should be noted that the RSRP reported in the basic MR data usually needs to be converted to the actual RSRP. For example, the actual RSRP = reported RSRP - 140.

[0070] In some embodiments, for the aforementioned user identifier, if it is a 4G cell, the 4G user identifier can be monitored, and if it is a 5G cell, the 5G identifier can be monitored.

[0071] Specifically, the 4G user identifier may include, but is not limited to, any of the following: MME-side S1 interface UE identifier (MME UES1 Application Protocol ID, MmeUeS1apId) and eNB-side S1 interface UE identifier (eNB UE S1 Application Protocol ID, ENBUeS1apId).

[0072] The 5G identifier may include, but is not limited to, any of the following: for 5G, it is the UE identifier of the NG interface on the AMF side (AMF UE NGApplication Protocol ID, AmfUeNgapId) and the UE identifier of the NG interface on the RAN side (RAN UE NG Application Protocol ID, RanUeNgapId).

[0073] In some embodiments, operators may use backfilling methods to add information such as latitude and longitude data, Subscription Permanent Identifier (SUPI) / International Mobile Subscriber Identity (IMSI), International Mobile Equipment Identity (IMEI), and Mobile Station International ISDN Number (MSISDN) to the basic MR data reported by users.

[0074] It should be noted that the above-mentioned vehicle and card trajectory table is usually compiled from raw data points reported periodically by the vehicle's electronic equipment, mainly including vehicle identification (SUPI / IMSI, IMEI, MSISDN, etc.), time, latitude and longitude data, etc.

[0075] Understandably, underground parking lot identification devices can determine which MR data was reported by onboard electronic devices and which was reported by other mobile terminals (such as mobile phones) based on the vehicle identifiers included in the vehicle card trajectory table. In other words, they can filter out the user-level basic MR data of the vehicle card and its backfilled data.

[0076] In some embodiments, the above-mentioned vehicle-mounted MR data includes: cell identifier, received signal strength, reporting time, and latitude and longitude data.

[0077] It is understandable that the aforementioned vehicle-mounted MR data may include the basic MR data reported by the vehicle and its corresponding backfill data.

[0078] In some embodiments, when the underground parking lot identification device obtains the vehicle MR data reported by at least one vehicle, it can sort all the vehicle MR data first by IMSI, and then sort the vehicle MR data belonging to the same IMSI by time. That is, it can first organize the data by vehicle, arrange all the vehicle MR data reported by the same vehicle together, and then sort all the vehicle MR data reported by the same vehicle by time.

[0079] Step 202: If the reporting time and received signal strength meet the first judgment condition, the underground parking lot identification device determines that the target area includes an underground parking lot without coverage.

[0080] It should be noted that for the specific details of step 202 above, please refer to the relevant descriptions of steps 202a to 202c below, which will not be repeated here in the embodiments of this application.

[0081] Step 203: If the cell type determined based on the cell identifier meets the second determination condition, the underground parking lot identification device determines that the target area includes the underground parking lot.

[0082] In some embodiments, the underground parking lot identification device can obtain the basic operating parameter data corresponding to the cell identifier in the vehicle-mounted MR data, so as to obtain the cell type included in the basic operating parameter data.

[0083] It is understandable that vehicle-mounted MR data and basic engineering parameter data can be linked through cell identifiers.

[0084] In some embodiments, the cell types described above may include, but are not limited to, any of the following: indoor cell, outdoor cell.

[0085] It should be noted that for the specific details of step 203 above, please refer to the relevant descriptions of steps 203a and 203b below, which will not be repeated here in the embodiments of this application.

[0086] It should be noted that the execution order of steps 202 and 203 described above is not limited in this embodiment. For example, step 202 can be executed first, followed by step 203; or step 203 can be executed first, followed by step 202; or steps 202 and 203 can be executed simultaneously. Figure 2 This example illustrates the process of executing step 202 first, followed by step 203.

[0087] Step 204: The underground parking lot identification device determines the location information of the target underground parking lot in the target area based on latitude and longitude data.

[0088] In some embodiments, the target underground parking lot is either an uncovered underground parking lot or a covered underground parking lot.

[0089] Understandably, when the underground parking lot identification device determines that the target area includes uncovered or covered underground parking lots, it can further combine the latitude and longitude data uploaded by the vehicle to determine the specific location of the uncovered or covered underground parking lot.

[0090] The underground parking lot identification method provided in this application allows the underground parking lot identification device to acquire vehicle-mounted MR data reported by at least one vehicle in a target area within a target time period. Based on the reporting time and received signal strength included in the vehicle-mounted MR data, the device determines whether the target area contains an uncovered underground parking lot; or based on the cell type corresponding to the cell identifier included in the vehicle-mounted MR data, it determines whether the target area contains a covered underground parking lot. In other words, the underground parking lot identification device can not only determine whether the target area contains an underground parking lot, but also, based on this, determine whether the target underground parking lot is uncovered or covered, and determine the network coverage status of the underground parking lot. Then, based on the acquired latitude and longitude data, the underground parking lot identification device can further determine the specific location information of the target underground parking lot, thus improving the accuracy of underground parking lot identification.

[0091] In some embodiments, combined with Figure 2 ,like Figure 3 As shown, step 202 above can be specifically implemented through steps 202a to 202c below.

[0092] Step 202a: If the reporting time of the on-board MR data reported by the first vehicle meets the preset time determination condition, the underground parking lot identification device determines that there is at least one valid uncovered location.

[0093] In some embodiments, the aforementioned effective uncovered location can be an inlet effective uncovered location or an outlet effective uncovered location.

[0094] In some embodiments, step 202a can be implemented by any one of steps A1 to A3 below, or by any other feasible means.

[0095] Step A1: If the reporting time interval between two adjacent vehicle MR data reported by the first vehicle is greater than the preset time, the underground parking lot identification device determines that there is an effective uncovered point at the entrance and an effective uncovered point at the exit.

[0096] In some embodiments, if the time interval between the Nth reported vehicle MR data and the N+1th reported vehicle MR data by user i (first vehicle) exceeds T1 (preset duration), i.e. Therefore, the Nth reported vehicle MR data is the last reported vehicle MR data of user i before entering the uncovered underground parking lot. Thus, the underground parking lot identification device can determine the existence of a valid uncovered entrance location based on this Nth reported vehicle MR data. ( ).

[0097] Correspondingly, the (N+1)th reported vehicle MR data is the first reported vehicle MR data by user i after leaving the uncovered underground parking lot. Therefore, the underground parking lot identification device can determine, based on this (N+1)th reported vehicle MR data, the existence of a valid uncovered exit point. ( ).

[0098] It is understandable that, within the target time period, the aforementioned first vehicle entered the uncovered underground parking lot and left the uncovered underground parking lot after being parked there for a period of time.

[0099] It should be noted that T1 can be used to indicate that the first vehicle has been parked in an uncovered underground parking lot for a period of time. The specific value of T1 can be set according to actual needs, and this embodiment of the application does not limit it.

[0100] Step A2: If the time interval between the reporting time of the first vehicle-mounted MR data reported by the first vehicle and the end time of the target time period is greater than the preset duration, the underground parking lot identification device determines that there is an effective uncovered point at the entrance.

[0101] In some embodiments, the first vehicle-mounted MR data may be the last vehicle-mounted MR data reported by the first vehicle within the target time period.

[0102] It is understandable that during the target time period, the first vehicle entered the uncovered underground parking lot and did not leave it; that is, at the end of the target time period, the first vehicle was still placed in the uncovered underground parking lot.

[0103] Step A3: If the time interval between the reporting time of the second vehicle-mounted MR data reported by the first vehicle and the start time of the target time period is greater than the preset duration, the underground parking lot identification device determines that there is an effective uncovered point at the exit.

[0104] In some embodiments, the second vehicle-mounted MR data may be the first vehicle-mounted MR data reported by the first vehicle within a target time period.

[0105] It is understandable that the first vehicle entered the uncovered underground parking lot before the target time period and left the uncovered underground parking lot during the target time period, that is, the first vehicle was placed in the uncovered underground parking lot at the beginning of the target time period.

[0106] In this way, the underground parking lot identification device can determine the effective uncovered points at the entrance or exit based on the vehicle MR data reported by the first vehicle within the target time period. This provides information support for the subsequent identification of underground parking lots, thereby improving the accuracy of subsequent identification of underground parking lots.

[0107] It is understandable that, since there is no network coverage in the underground parking lot, network interruption may occur when a vehicle enters the underground parking lot, thus interrupting the reporting of vehicle MR data until the vehicle leaves the underground parking lot, at which point the vehicle can reconnect to the network and resume the reporting of vehicle MR data.

[0108] Step 202b: If the received signal strength contained in the two adjacent vehicle MR data reported by the second vehicle meets the preset received signal strength condition, the underground parking lot identification device determines that there is a valid abrupt change point.

[0109] In some embodiments, the aforementioned effective steep change point can be an effective steep descent point at the entrance or an effective steep ascent point at the exit.

[0110] In some embodiments, the two adjacent vehicle-mounted MR data reported by the second vehicle may include third vehicle-mounted MR data and fourth vehicle-mounted MR data.

[0111] In some embodiments, the reporting time of the third vehicle-mounted MR data may be earlier than that of the fourth vehicle-mounted MR data.

[0112] In some embodiments, step 202b above may be implemented by step B1 or step B2 below, or may be implemented by any other feasible means.

[0113] Step B1: When the difference between the received signal strength of the third vehicle-mounted MR data and the received signal strength of the fourth vehicle-mounted MR data is greater than a preset threshold, and the received signal strength of the fourth vehicle-mounted MR data is less than the preset received signal strength, the underground parking lot identification device determines that there is an effective steep drop point at the entrance.

[0114] In some embodiments, if the RSRP of the Mth reported vehicle MR data (third vehicle MR data) and the RSRP of the (M+1)th reported vehicle MR data (fourth vehicle MR data) by user j (second vehicle) satisfy... ,and ,at the same time If the Mth reported vehicle MR data is detected, then user j is considered to have experienced a steep descent. Therefore, the underground parking lot identification device can determine the existence of a valid steep descent point at the entrance based on this Mth reported vehicle MR data. ( ).

[0115] It should be noted that the above (Preset threshold) can be used to indicate that a change has occurred in RSRP, for example ;

[0116] The above (Preset Received Signal Strength) can be used to represent the minimum RSRP value required to meet user communication needs, for example, ;

[0117] The above It can be used to represent the interval between consecutive adjacent reports of vehicle-mounted MR data, for example .

[0118] Understandably, before a vehicle enters an underground parking lot without network coverage, it can maintain a relatively good signal, meaning its RSRP remains at a high level. However, as the vehicle prepares to enter the underground parking lot, the RSRP in the vehicle's reported MR data will drop sharply due to the lack of network coverage. Furthermore, since the vehicle continues to operate within the underground parking lot without coverage, its subsequent RSRP will remain at a low level, or it may experience a loss of RSRP data due to interrupted MR data reporting, until the vehicle leaves the underground parking lot and resumes reporting MR data.

[0119] Step B2: When the difference between the received signal strength of the fourth vehicle-mounted MR data and the received signal strength of the third vehicle-mounted MR data is greater than a preset threshold, and the received signal strength of the third vehicle-mounted MR data is less than the preset received signal strength, the underground parking lot identification device determines that there is an effective steep rise point at the exit.

[0120] In some embodiments, if the RSRP of the Kth reported vehicle MR data (third vehicle MR data) and the RSRP of the (K+1)th reported vehicle MR data (fourth vehicle MR data) by user j (second vehicle) satisfy... ,and ,at the same time If the Kth reported vehicle MR data is detected, then user j is considered to have experienced a steep ascent. Therefore, the underground parking lot identification device can determine, based on this Kth reported vehicle MR data, the existence of a valid exit steep ascent point. ( ).

[0121] It should be noted that the above (Preset threshold) can be used to indicate that a change has occurred in RSRP, for example .

[0122] Understandably, when a vehicle is in an uncovered underground parking lot, it may be in a low-signal or no-signal state, meaning its RSRP remains at a low level, or RSRP data may be missing due to interrupted onboard MR data. When the vehicle prepares to leave the uncovered underground parking lot, it can resume reporting onboard MR data and, after leaving, will be in a state with a better signal, meaning its RSRP will remain at a high level. Therefore, the RSRP in the vehicle's reported onboard MR data will experience a sharp increase.

[0123] It should be noted that the above and The values ​​can be the same or different.

[0124] It should be noted that the above , , , The specific value can be set according to actual needs, and this application embodiment does not limit it.

[0125] In some embodiments of this application, the cell identifiers corresponding to the third vehicle-mounted MR data and the fourth vehicle-mounted MR data may be the same, so as to reduce or avoid the sharp change in RSRP caused by the change of the cell connected to the second vehicle.

[0126] In this way, the underground parking lot identification device can determine the effective steep drop point at the entrance or the effective steep rise point at the exit based on the received signal strength of the on-board MR data reported by the second vehicle within the target time period. This provides information support for the effective steep change points in subsequent underground parking lot identification, thereby improving the accuracy of subsequent underground parking lot identification.

[0127] Step 202c: If the number of effective uncovered points and effective steep change points included in the target sub-area meets the first preset value condition, the underground parking lot identification device determines that the target sub-area includes an uncovered underground parking lot.

[0128] In some embodiments, the target sub-region can be any sub-region included in the target region.

[0129] In some embodiments, if within a certain area (target sub-region, such as a circular area with a radius of 100m), there are a certain number of uncovered exit / entrance points. ( (At the same time, there are a certain number of effective steep descent points at the entrances.) ( If the underground parking lot identification device determines that the area is the entrance to an uncovered underground parking lot, then the underground parking lot identification device can identify the area as such.

[0130] In some embodiments, if within a certain area (target sub-region, such as a circular area with a radius of 100m), there are a certain number of effective uncovered exit points. ( At the same time, there are a certain number of effective steep rise points in exports. If so, the underground parking lot identification device can determine that the area is the exit of an uncovered underground parking lot.

[0131] It should be noted that the above-mentioned first preset numerical condition can be determined according to actual needs, and this application embodiment does not limit it here.

[0132] It is understandable that, since there are situations in above-ground parking lots where the on-board MR data may suddenly stop being reported due to the vehicle being turned off, or may suddenly resume being reported due to the vehicle being restarted, the underground parking lot identification method provided in this application can improve the accuracy of identifying underground parking lots by adding a limitation on the sharp change of RSRP.

[0133] In this way, the underground parking lot identification device can determine whether the target sub-area includes an uncovered underground parking lot based on the characteristics of uncovered underground parking lots and effective uncovered points and effective steep change points, thereby improving the accuracy of identifying uncovered underground parking lots.

[0134] In some embodiments, combined with Figure 3 ,like Figure 4 As shown, in conjunction with the above steps 202a to 202c, step 204 can be specifically implemented through the following steps 204a to 204c.

[0135] Step 204a: The underground parking lot identification device determines the location information of the effective uncovered points based on the latitude and longitude data reported by the first vehicle.

[0136] In some embodiments, the underground parking lot identification device can record the latitude and longitude data corresponding to the Nth vehicle-mounted MR data as the location information of an effective uncovered point at the entrance; or, it can record the latitude and longitude data corresponding to the (N-1)th vehicle-mounted MR data as the location information of an effective uncovered point at the entrance; or, it can take the center point based on the latitude and longitude data corresponding to the Nth and (N-1)th vehicle-mounted MR data to... ( This can be denoted as the location information of a valid, uncovered entry point; or, based on any other feasible method, the location information of a valid, uncovered entry point can be determined.

[0137] In some embodiments, the underground parking lot identification device can record the latitude and longitude data corresponding to the (N+1)th vehicle-mounted MR data as the location information of an effective uncovered exit point; or, it can record the latitude and longitude data corresponding to the (N+2)th vehicle-mounted MR data as the location information of an effective uncovered exit point; or, it can take the center point based on the latitude and longitude data corresponding to the (N+1)th and (N+2)th vehicle-mounted MR data. ( ), in order to ( This can be denoted as the location information of an effective uncovered exit point; or, based on any other feasible method, the location information of an effective uncovered exit point can be determined.

[0138] It is understandable that the method by which the underground parking lot identification device determines the location information of the effective uncovered points based on the latitude and longitude data reported by the first vehicle can be determined according to actual needs, and the embodiments of this application are not limited here.

[0139] Step 204b: The underground parking lot identification device determines the location information of the effective steep change points based on the latitude and longitude data reported by the second vehicle.

[0140] In some embodiments, the underground parking lot identification device can record the latitude and longitude data corresponding to the Mth vehicle-mounted MR data as the location information of an effective steep descent point at the entrance; or, it can record the latitude and longitude data corresponding to the (M+1)th vehicle-mounted MR data as the location information of an effective steep descent point at the entrance; or, it can take the center point based on the latitude and longitude data corresponding to the Mth vehicle-mounted MR data and the (M+1)th vehicle-mounted MR data. ( ),Will ( This can be recorded as the location information of an effective steep descent point at an entrance; or, based on any other feasible method, the location information of an effective steep descent point at an entrance can be determined.

[0141] In some embodiments, the underground parking lot identification device can record the latitude and longitude data corresponding to the Kth vehicle-mounted MR data as the location information of an effective steep exit point; or, it can record the latitude and longitude data corresponding to the (K+1)th vehicle-mounted MR data as the location information of an effective steep exit point; or, it can take the center point based on the latitude and longitude data corresponding to the Kth vehicle-mounted KR data and the (K+1)th vehicle-mounted MR data. ( ),Will ( This can be recorded as the location information of an effective steep rise point at an exit; or, based on any other feasible method, the location information of an effective steep rise point at an exit can be determined.

[0142] It is understandable that the method by which the underground parking lot identification device determines the location information of the effective steep change point based on the latitude and longitude data reported by the second vehicle can be determined according to actual needs, and this application embodiment does not limit it here.

[0143] Step 204c: The underground parking lot identification device determines the location information of the uncovered underground parking lot based on the location information of each valid uncovered point and the location information of each valid steep change point.

[0144] In some embodiments, the aforementioned effective uncovered location can be an inlet effective uncovered location or an outlet effective uncovered location.

[0145] In some embodiments, the aforementioned effective steep change point can be an effective steep descent point at the entrance or an effective steep ascent point at the exit.

[0146] In some embodiments, step 204c can be implemented by steps 204c1 to 204c3.

[0147] Step 204c1: The underground parking lot identification device determines the entrance location information of the uncovered underground parking lot based on the location information of the effective uncovered points at each entrance and the location information of the effective steep drop points at each entrance.

[0148] Step 204c2: The underground parking lot identification device determines the exit location information of the uncovered underground parking lot based on the location information of each effective uncovered point and the location information of each effective steep rise point.

[0149] Step 204c3: The underground parking lot identification device determines the location information of the uncovered underground parking lot based on the entrance location information and the exit location information of the uncovered underground parking lot.

[0150] Understandably, an underground parking lot identification device can determine the location information of the entrance to an uncovered underground parking lot in a target area based on the location information of at least one valid uncovered point at the entrance and the location information of a valid steep descent point at the entrance corresponding to a vehicle. Correspondingly, the underground parking lot identification device can determine the location information of the exit of an uncovered underground parking lot in a target area based on the location information of at least one valid uncovered point at the exit and the location information of a valid steep descent point at the exit. Furthermore, the underground parking lot identification device can determine the location information of an uncovered underground parking lot based on the location information of its exit and entrance.

[0151] In this way, the underground parking lot identification device can first determine the location of the entrance and exit of the uncovered underground parking lot, and then further determine the specific location of the uncovered underground parking lot, thereby improving the accuracy of locating the underground parking lot.

[0152] In this way, the underground parking lot identification device can determine whether there is an uncovered underground parking lot based on the vehicle-mounted MR data, and further determine the specific location of the uncovered underground parking lot, thereby achieving accurate identification of the underground parking lot.

[0153] In some embodiments, after step 202 above, the underground parking lot identification method provided in this application embodiment may further include step 301 below.

[0154] Step 301: The underground parking lot identification device generates the first work order information.

[0155] In some embodiments, the first work order information described above is used to instruct the addition of a base station for an underground parking lot without coverage.

[0156] Understandably, if the underground parking lot identification device identifies that the target area includes an underground parking lot without coverage, the underground parking lot identification device can automatically generate a work order to be dispatched to relevant personnel, so that the relevant personnel can add a base station for the underground parking lot without coverage, so that the underground parking lot can be covered by the network.

[0157] In this way, the underground parking lot identification device can add base stations to the identified underground parking lots that are not covered, so that they can become covered underground parking lots, thereby reducing the inconvenience caused by the lack of network coverage and improving the user experience of using underground parking lots.

[0158] In some embodiments, combined with Figure 2 ,like Figure 5 As shown, step 203 can be implemented through steps 203a and 203b.

[0159] Step 203a: When the cell types corresponding to the two adjacent vehicle MR data reported by the third vehicle are different, the underground parking lot identification device determines that there is an effective coverage point.

[0160] In some embodiments, the cell types described above may include, but are not limited to, any of the following: indoor cell, outdoor cell.

[0161] In some embodiments, the aforementioned effective coverage points can be effective coverage points at the entrance or effective coverage points at the exit.

[0162] In some embodiments, the two adjacent vehicle-mounted MR data reported by the third vehicle may include the fifth vehicle-mounted MR data and the sixth vehicle-mounted MR data.

[0163] In some embodiments, the reporting time of the fifth vehicle-mounted MR data may be earlier than that of the sixth vehicle-mounted MR data.

[0164] In some embodiments, step 203a can be implemented by step C1 or step C2, or by any other feasible means.

[0165] Step C1: When the cell type corresponding to the fifth vehicle-mounted MR data is an outdoor cell and the cell type corresponding to the sixth vehicle-mounted MR data is an indoor cell, the underground parking lot identification device determines that there is an effective coverage point at the entrance.

[0166] In some embodiments, the underground parking lot identification device can identify the location of the vehicle card in the vehicle MR data when the vehicle card user service cell changes from an outdoor cell to an indoor cell, so as to use it as an effective entry point coverage location.

[0167] Specifically, if the cell corresponding to the Nth reported vehicle MR data (the fifth vehicle MR data) by user i (the third vehicle) is an outdoor cell, and the cell corresponding to the (N+1)th reported vehicle MR data (the sixth vehicle MR data) is an indoor cell, then the underground parking lot identification device can determine, based on these N vehicle MR data and the (N+1)th vehicle MR data, that there exists an effective coverage point at the entrance. ( ).

[0168] Step C2: If the cell type corresponding to the fifth vehicle-mounted MR data is an indoor cell and the cell type corresponding to the sixth vehicle-mounted MR data is an outdoor cell, the underground parking lot identification device determines that there is an effective coverage point for an exit.

[0169] In some embodiments, the underground parking lot identification device can identify the location of the vehicle card in the vehicle MR data when the vehicle card user service cell changes from an indoor cell to an outdoor cell, so as to use it as an effective entry point coverage location.

[0170] Specifically, if the cell corresponding to the N+Xth reported vehicle MR data (the fifth vehicle MR data) of user i (the third vehicle) is an indoor cell, and the cell corresponding to the N+X+1th reported vehicle MR data (the sixth vehicle MR data) is an outdoor cell, then the underground parking lot identification device can determine the existence of an effective coverage point at the exit based on the N+Xth and N+X+1th vehicle MR data. ( ).

[0171] In this way, the underground parking lot identification device can determine the effective coverage points at the entrance or exit based on the cell type corresponding to the vehicle MR data reported by the third vehicle within the target time period. This provides information support for the effective coverage points of the underground parking lot in the subsequent identification, thereby improving the accuracy of the subsequent identification of the underground parking lot.

[0172] Step 203b: If the number of effective coverage points included in the target sub-area meets the second preset value condition, the underground parking lot identification device determines that the target sub-area includes the underground parking lot.

[0173] In some embodiments, the target sub-region can be any sub-region included in the target region.

[0174] In some embodiments, if there are a certain number of entrances with effective coverage points within a certain area (target sub-region, such as a circular area with a radius of 100m). ( If many vehicle card users change from outdoor to indoor parking areas in this area, the underground parking lot identification device can determine that the area is the entrance to the underground parking lot.

[0175] In some embodiments, if there are a certain number of effective exit coverage points within a certain area (target sub-area, such as a circular area with a radius of 100m). ( If many vehicle card users change from indoor to outdoor parking areas in this area, the underground parking lot identification device can determine that the area is the exit of the underground parking lot.

[0176] It should be noted that the above-mentioned second preset numerical conditions can be determined according to actual needs, and this application embodiment does not limit them here.

[0177] In this way, the underground parking lot identification device can determine the effective coverage points by the characteristics of the underground parking lot, and further determine whether the target sub-area includes the underground parking lot based on the effective coverage points, thereby improving the accuracy of identifying the underground parking lot.

[0178] In some embodiments, combined with Figure 5 ,like Figure 6 As shown, in combination with steps 203a and 203b above, step 204 above can be specifically implemented through steps 204d and 204e below.

[0179] Step 204d: The underground parking lot identification device determines the location information of the effective coverage points based on the latitude and longitude data reported by the third vehicle.

[0180] In some embodiments, the underground parking lot identification device can record the latitude and longitude data corresponding to the Nth vehicle-mounted MR data as the location information of an effective coverage point of an entrance; or, it can record the latitude and longitude data corresponding to the (N+1)th vehicle-mounted MR data as the location information of an effective coverage point of an entrance; or, it can take the center point based on the latitude and longitude data corresponding to the Nth and (N+1)th vehicle-mounted MR data. ( ),Will ( This can be denoted as the location information of an effective coverage point of an entrance; or, based on any other feasible method, the location information of an effective coverage point of an entrance can be determined.

[0181] In some embodiments, the underground parking lot identification device can record the latitude and longitude data corresponding to the N+Xth vehicle-mounted MR data as the location information of an effective coverage point of an exit; or, it can record the latitude and longitude data corresponding to the N+X+1th vehicle-mounted MR data as the location information of an effective coverage point of an exit; or, it can take the center point based on the latitude and longitude data corresponding to the N+Xth vehicle-mounted MR data and the latitude and longitude data corresponding to the N+X+1th vehicle-mounted MR data. ( ),Will ( This can be denoted as the location information of an effective coverage point of an exit; or, based on any other feasible method, the location information of an effective coverage point of an exit can be determined.

[0182] It is understandable that the method by which the underground parking lot identification device determines the location information of the effective coverage points based on the latitude and longitude data reported by the third vehicle can be determined according to actual needs, and this application embodiment does not limit it here.

[0183] Step 204e: The underground parking lot identification device determines the location information of the covered underground parking lot based on the location information of each effective coverage point.

[0184] In some embodiments, the aforementioned effective coverage points can be effective coverage points at the entrance or effective coverage points at the exit.

[0185] In some embodiments, step 204e can be implemented by steps 204e1 to 204e3.

[0186] Step 204e1: The underground parking lot identification device determines the entrance location information of the covered underground parking lot based on the location information of each entrance's effective coverage point.

[0187] Step 204e2: The underground parking lot identification device determines the exit location information of the covered underground parking lot based on the location information of each effective coverage point.

[0188] Step 204e3: The underground parking lot identification device determines the location information of the underground parking lot based on the entrance location information and the exit location information of the underground parking lot.

[0189] Understandably, an underground parking lot identification device can determine the location information of the entrance covering the underground parking lot within a target area based on the location information of the effective coverage point of at least one vehicle's entrance; correspondingly, the underground parking lot identification device can determine the location information of the exit covering the underground parking lot within a target area based on the location information of the effective coverage point of at least one vehicle's exit. Furthermore, the underground parking lot identification device can determine the location information of the covered underground parking lot based on the location information of both the exit and the entrance.

[0190] In this way, the underground parking lot identification device can first determine the location of the entrance and exit of the underground parking lot, and then further determine the specific location of the underground parking lot, thereby improving the accuracy of locating the underground parking lot.

[0191] In this way, the underground parking lot identification device can determine whether the underground parking lot is included based on the vehicle-mounted MR data, and further determine the specific location of the underground parking lot, thereby achieving accurate identification of the underground parking lot.

[0192] In some embodiments, after step 202 above, the underground parking lot identification method provided in this application embodiment may further include step 401 below.

[0193] Step 401: If the received signal strength included in the target vehicle MR data meets the third determination condition, the underground parking lot identification device determines that the covered underground parking lot is a weakly covered underground parking lot.

[0194] In some embodiments, the target vehicle MR data mentioned above includes vehicle MR data reported by at least one vehicle in a covered underground parking lot.

[0195] In some embodiments, if the vehicle card user service cell corresponding to a vehicle changes from an outdoor cell to an indoor cell, and all subsequent cells are indoor cells, the underground parking lot identification device can determine the vehicle MR data reported by the vehicle as the target vehicle MR data.

[0196] In some embodiments, for a vehicle whose corresponding vehicle-mounted user serving cell changes from an outdoor cell to an indoor cell and then changes back from the indoor cell to the outdoor cell, the underground parking lot identification device may determine the intermediate vehicle-mounted MR data reported by the vehicle while it is in the indoor cell as the above-mentioned target vehicle-mounted MR data.

[0197] It can be understood that the underground parking lot identification device may perform statistics based on the RSRP included in the vehicle-mounted MR data (all vehicle-mounted MR data from the (N+1)th to the (N+X)th) reported by the vehicle-mounted card within the area of the underground parking lot, so as to evaluate the coverage condition of the underground parking lot.

[0198] In some embodiments, the above-mentioned third determination condition may be that the number of RSRP values less than a preset RSRP threshold is greater than or equal to a preset number; or may be that the proportion of RSRP values less than the preset RSRP threshold is greater than or equal to a preset threshold.

[0199] Exemplarily, if the proportion of sample points where RSRP<Y is higher than the preset threshold, the underground parking lot with such coverage is a weak coverage underground parking lot.

[0200] It should be noted that the specific value of Y described above may be determined according to actual requirements, which is not limited in the embodiments of the present application.

[0201] In this way, on the basis of determining that the target area includes a covered underground parking lot, the underground parking lot identification device can further pay attention to the received signal strength, that is, the network quality in the covered underground parking lot, so that corresponding network optimization measures can be subsequently performed on the weak coverage underground parking lot, so as to reduce the inconvenience caused by weak network coverage and improve the user experience of users using the underground parking lot.

[0202] In some embodiments, after the above step 401, the underground parking lot identification method provided in the embodiments of the present application may further include the following step 402.

[0203] Step 402: The underground parking lot identification device generates second work order information.

[0204] In some embodiments, the above-mentioned second work order information is used to instruct to perform network optimization for the weak coverage underground parking lot.

[0205] If it is identified that the underground parking lot has coverage but weak coverage exists, the device automatically generates a work order and dispatches it to relevant personnel to carry out work related to network optimization.

[0206] Understandably, if the underground parking identification device identifies a target area that includes a poorly covered underground parking lot, the device can automatically generate a work order to be dispatched to relevant personnel. This allows the relevant personnel to optimize the network for the poorly covered underground parking lot and improve its network quality.

[0207] In this way, the underground parking lot identification device can optimize the network of the identified underground parking lot with weak coverage, so that the underground parking lot with weak coverage can provide users with a network that meets their actual needs, thereby reducing the inconvenience caused by weak network coverage and improving the user experience of using the underground parking lot.

[0209] S1. Obtain the cell's user-level MR data and its backfilled information, including user identifiers (MmeUeS1apId and ENBUeS1apId for 4G; AmfUeNgapId and RanUeNgapId for 5G; for 4G cells, use the 4G user identifier, and for 5G cells, use the 5G identifier), time, cell ID, RSRP, SUCI / IMSI, IMEI, MSISDN, latitude and longitude data, etc. (Note: The RSRP reported in the MR needs to be converted to the actual RSRP; generally, the actual RSRP = reported RSRP - 140).

[0212] S4. Identify underground parking lots.

[0213] 1. Identification in uncovered underground parking lots:

[0214] (1) Identification of parking entrances without coverage:

[0215] First, sort the vehicle MR data of all vehicle card users by IMSI, and then sort the data of the same IMSI by time.

[0216] If the time interval between the Nth and N+1th reported vehicle MR data by user i exceeds T1, that is ( Then, the Nth reported vehicle MR data is the last vehicle MR data reported by the user. The center point is taken from the latitude and longitude data corresponding to the Nth vehicle MR data and the latitude and longitude data corresponding to the (N-1)th vehicle MR data. ( ),Will ( () is recorded as an effective uncovered entry point.

[0217] If the RSRP of the Mth reported vehicle MR data by user j and the RSRP of the (M+1)th reported data satisfy... ,and ,at the same time If a sharp drop occurs, it is considered that user j has experienced a sudden drop. The center point is then taken from the latitude and longitude data corresponding to the Mth vehicle MR data and the latitude and longitude data corresponding to the (M+1)th vehicle MR data. ( ),Will ( This is recorded as an effective steep descent point at the entrance.

[0218] If within a certain area (such as a circular area with a radius of 100m), there are a certain number of ( ), and at the same time, a certain number ( If the area is marked as such, then it is the entrance to the underground parking lot.

[0219] It should be noted that the requirement for a certain number of steep drops is because in above-ground parking lots, many cars will turn off their engines, resulting in many vehicles moving from covered to uncovered states.

[0220] (2) Identification of parking exits without coverage:

[0221] First, sort the vehicle MR data of all vehicle card users by IMSI, and then sort the data of the same IMSI by time.

[0222] If the time interval between the Nth and N+1th reported vehicle MR data by user i exceeds T1, that is ( Then, the (N+1)th reported vehicle MR data is the first vehicle MR data reported by the user. The center point is taken from the latitude and longitude data corresponding to the (N+1)th vehicle MR data and the latitude and longitude data corresponding to the (N+2)th vehicle MR data. ( ),Will ( This is recorded as an effective uncovered exit point.

[0223] If the RSRP of the Kth reported vehicle MR data and the RSRP of the (K+1)th reported vehicle MR data by user j satisfy... ,and ,at the same time If a sharp rise occurs in user j, then the latitude and longitude data corresponding to the Kth vehicle MR data point and the latitude and longitude data corresponding to the (K+1)th vehicle MR data point are taken as the center point. ,Will This is recorded as an effective steep rise point at the exit.

[0224] If within a certain area (such as a circular area with a radius of 100m), there are a certain number of ( ), and at the same time, a certain number If so, then this area is the exit of the underground parking lot.

[0225] 2. Covered underground parking lot identification:

[0226] (1) Coverage for underground parking lot entrance identification:

[0227] Identify the location of the vehicle MR data when the service cell for a vehicle MR user changes from an outdoor cell to an indoor cell. The vehicle MR data for all vehicle MR users can be sorted first by IMSI, and then by time for the same IMSI.

[0228] If the cell corresponding to the Nth reported vehicle MR data is an outdoor cell, and the cell corresponding to the (N+1)th reported vehicle MR data is an indoor cell, then the center point of the latitude and longitude data corresponding to the Nth and (N+1)th vehicle MR data is taken. ( ),Will ( () is recorded as an effective coverage point of an entrance.

[0229] If within a certain area (e.g., a circular area with a radius of 100m), there are a certain number of ( If many car card users are moving from an outdoor community to an indoor community in this area, then the area is determined to be the entrance to an underground parking lot.

[0230] (2) Coverage for underground parking lot exit identification:

[0231] Identify the location of the vehicle MR data when the service cell for a vehicle MR user changes from an indoor cell to an outdoor cell. The vehicle MR data for all vehicle MR users can be sorted first by IMSI, and then by time for the same IMSI.

[0232] If the cell corresponding to the N+Xth reported in-vehicle MR data of the user is an indoor cell, and the cell corresponding to the N+X+1th reported in-vehicle MR data is an outdoor cell, the center point of the latitude and longitude data corresponding to the N+Xth in-vehicle MR data and the latitude and longitude data corresponding to the N+X+1th in-vehicle MR data is taken ( ), ( ) is recorded as an exit effective coverage point.

[0233] If there are many such points in a certain area (for example, a circular area with a radius of 100m), that is, many vehicle-mounted users change from the indoor cell to the outdoor cell in this area, it is determined that this area is the exit of an underground parking lot.

[0234] (3) Evaluation of underground parking lot coverage status:

[0235] All in-vehicle MR data from the N+1th to the N+Xth are the in-vehicle MR data of the vehicle-mounted user in the underground parking lot, and the coverage status of the underground parking lot can be evaluated according to the statistics of RSRP of these in-vehicle MR data.

[0236] If the proportion of sample points with RSRP<Y is higher than a certain threshold, the underground parking lot is a weak coverage parking lot.

[0237] S5. If it is identified that there is no coverage in the underground parking lot, the device automatically generates a work order and dispatches it to relevant personnel, and a new base station needs to be added to the underground parking lot.

[0238] If it is identified that the underground parking lot has coverage but weak coverage exists, the device automatically generates a work order and dispatches it to relevant personnel, and network optimization related work needs to be carried out.

[0239] In this way, the underground parking lot identification device can acquire the in-vehicle MR data reported by at least one vehicle in the target area within the target time period, so as to determine whether the target area includes an uncovered underground parking lot according to the reporting time and received signal strength included in the in-vehicle MR data; or determine whether the target area includes a covered underground parking lot according to the cell type corresponding to the cell identifier included in the in-vehicle MR data. That is, the underground parking lot identification device can not only determine whether the target area includes an underground parking lot, but also on this basis, determine whether the target underground parking lot is an uncovered underground parking lot or a covered underground parking lot, and can determine the network coverage status of the underground parking lot. Then, the underground parking lot identification device can further determine the specific position information of the target underground parking lot based on the acquired latitude and longitude data, which improves the accuracy of identifying the underground parking lot.

[0240] In other words, the underground parking lot identification device can overlay the vehicle card trajectory table with the wireless signal measurement report and its backfill information collected by the network between the user equipment and the base station, and use the signal change characteristics of the vehicle card to determine the location of the underground parking lot. It can accurately identify the signal status of the vehicle card in the underground parking lot, and is highly practical and accurate.
