[0048] The example embodiments will be described in detail herein with reference to the accompanying drawings. When the following description refers to accompanying drawings, unless otherwise specified, the same numbers in different drawings represent the same or similar elements. The implementations described in the following example embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0049] Figure 1 Fig. 4 shows a schematic diagram of a signal coverage range determination system corresponding to a signal coverage range determination method according to an example embodiment of the present application. As shown in Fig. 4, the signal coverage range determination system can include a 4G base station 110, a 5G base station 120, and a 5G terminal 130. Figure 1

[0050] With the development of communication technology, the construction of 5G networks has been completed, but there are still areas with weak or no coverage. Generally, in order to ensure the continuity of user services, in areas with weak 5G network coverage, the 5G terminal needs to switch from the 5G network to the 4G network for services, and correspondingly, the 5G terminal 130 switches from maintaining a communication connection with the 5G base station 120 to maintaining a communication connection with the 4G base station 110; while in areas with strong 5G network coverage, it can switch back from the 4G network to the 5G network for services, and correspondingly, the 5G terminal 130 switches from maintaining a connection with the 4G base station 110 to maintaining a connection with the 5G base station 120; wherein the 5G terminal refers to a terminal that can access the 5G base station and has 5G communication function. ​

[0051] Since the 5G positioning technology is not mature, the current 5G terminal does not support MDT (Minimization of Drive-Tests, Minimization of Drive-Tests) positioning, and the current 5G camping threshold is relatively high, usually set at about -112dbm, and when the 5G network coverage threshold is low, the 5G terminal will camp on the 4G network in advance, therefore, it is difficult to identify the weak coverage range of the 5G signal through the MR (Measurement Report, Measurement Report) reported on the 5G network.

[0052] In order to realize the determination of the weak coverage range of the 5G signal, in the embodiment of the application, the 4G base station 110 is configured with a 5G inter-system measurement frequency point, so that the 5G terminal can scan the 5G signal based on the 5G inter-system measurement frequency point when camping on the 4G network, and feed back the 5G signal data obtained by scanning to the 4G base station 110 through the 4G network, realizing the collection of the 5G signal by the 4G base station.

[0053] Figure 2 The flowchart of the signal coverage range determination method provided by an exemplary embodiment of the application is shown, which can be executed by a network device, which can be implemented as a management device on the side of the 4G base station, as shown in Figure 2 The signal coverage range determination method can include the following steps:

[0054] Step 210, in the case where the target terminal camps on the 4G network, the 5G inter-system frequency point information is issued to the target terminal; the target terminal is a terminal supporting 5G communication function.

[0055] If the coverage threshold of the 5G network is higher than the camping threshold of the 5G terminal, the target terminal will prefer to camp on the 5G network; therefore, when the target terminal, i.e. the 5G terminal, camps on the 4G network, it indicates that the coverage threshold of the 5G network in the current area is lower than the camping threshold of the 5G terminal, i.e. the target terminal is in the weak coverage range of the 5G signal.

[0056] In the embodiment of the application, the network device (i.e. the management device on the side of the 4G base station) is configured with a 5G inter-system frequency point, which is used to receive the 5G signal data reported by the 5G terminal through the 4G network, therefore, the 4G side terminal issues the 5G inter-system frequency point information to the target terminal, instructing the target terminal to perform signal scanning based on the 5G inter-system frequency point information, and collect 5G signal data.

[0057] Step 220, receiving the measurement report reported by the target terminal, the measurement report containing 4G measurement information and 5G signal data; the 5G signal data is obtained by the target terminal based on the 5G inter-system frequency point information; the 4G measurement information contains the positioning information of the 4G signal.

[0058] In the embodiment of the present application, the 4G measurement information and the 5G signal data are contained in the same measurement report.

[0059] Optionally, the 4G measurement information contains MR information and MDT information; the MR information contains the wireless measurement information of the 4G network, and the MDT information contains the positioning information of the 4G signal; the positioning information can be implemented as latitude and longitude information.

[0060] At step 230, the positioning information of the 5G signal is determined based on the measurement report.

[0061] In the embodiment of the present application, the measurement report contains both the 4G measurement information and the 5G signal data, so that the 4G base station can determine the positioning information of the 5G signal based on the positioning information of the 4G signal in the 4G measurement information.

[0062] At step 240, the weak coverage range of the 5G signal is determined based on the positioning information of the 5G signal.

[0063] In summary, the signal coverage range determination method provided in the embodiment of the present application utilizes the feature that the 4G network can collect position information, and makes the 5G terminal report the measurement report containing both the 4G measurement information and the 5G signal information through the 4G network by the 4G base station issuing the 5G inter-system frequency point information to the 5G terminal, and the 4G measurement information contains the positioning information of the 4G signal, so that the positioning information of the 5G signal can be determined based on the measurement report, and the weak coverage range of the 5G signal can be determined based on the positioning information of the 5G signal when the target terminal resides in the 4G network. Through the above method of filling the positioning information of the 5G signal based on the 4G inter-system measurement report, the 5G weak coverage range can be determined in real time, the dynamic detection of the 5G weak coverage range is realized, and the determination effect of the 5G weak coverage range is improved.

[0064] In the embodiment of the present application, in order to realize the collection of the 5G signal by the 4G base station, the 4G base station is a base station of a target base station version, and the base station version of the 4G base station can be V100R017C10SPC230 or above, for example. After the 4G base station is determined, the 5G inter-system frequency point is configured for the 4G base station, the period of the measurement report file is set, and the subscription of the measurement report is started, so that the 4G base station can collect data.

[0065] Figure 3 A flowchart of a signal coverage range determination method provided by an example embodiment of the present application is shown, which can be executed by a network device, which can be implemented as a management device on the side of a 4G base station, as shown in the figure, and the signal coverage range determination method can include the following steps: Figure 3 ​

[0066] Step 310, in the case that the target terminal resides in the 4G network, issuing 5G inter-system frequency point information to the target terminal; the target terminal is a terminal supporting 5G communication function.

[0067] Step 320, receiving a measurement report reported by the target terminal, the measurement report containing 4G measurement information and 5G signal data; the 5G signal data is obtained by the target terminal based on the 5G inter-system frequency point information for signal scanning; the 4G measurement information contains positioning information of the 4G signal.

[0068] The network device receives a measurement report reported by the target terminal through the 4G network, the measurement report being generated based on 4G measurement information and 5G measurement information; the measurement report contains both 4G measurement information and 5G measurement information.

[0069] The positioning of the 4G signal contained in the 4G measurement information can be collected based on known 4G positioning technology, and the application does not specify the acquisition method of the positioning information of the 4G signal.

[0070] Step 330, according to the alignment relationship between the 4G measurement information and the 5G signal data in the measurement report, determining the positioning information of the 4G signal contained in the 4G measurement information as the positioning information of the corresponding 5G signal.

[0071] Since there is both 4G measurement information and 5G signal data for the same measurement information in the same measurement report, the network device can separately analyze the positioning information of the 4G signal in the 4G measurement information and the 5G signal data, and correspond the positioning information of the 4G signal with the 5G signal data, so as to determine the positioning information of the 5G signal data of each measurement information. Figure 4 A schematic diagram of the measurement report provided by an example embodiment of the application is shown as follows, Figure 4 As shown in the same measurement report, both 4G measurement information 410 and 5G signal data 420 are contained, and the 4G measurement information 410 and the 5G signal data 420 have a corresponding relationship, so the positioning information of the 4G signal in the 4G measurement information can be determined as the positioning information of the corresponding 5G signal data.

[0072] In order to further supplement the positioning information of the 5G signal data, in the embodiment of the application, a method for determining the positioning information of the 5G signal data based on the 4 / 5G switching fallback event is also provided to determine the positioning information of the 5G signal data at the 4 / 5G switching moment; the process can include:

[0073] In the case that there is a 4G network and 5G network switching event, obtaining a 5G measurement report reported by the target terminal at a target time point;

[0074] The terminal tag and the timestamp information included in the 5G measurement report are matched in the 4G positioning information database to obtain the positioning information of the 5G signal. The 4G positioning information database is constructed based on the positioning information of the 4G signal included in the 4G measurement information reported by the target terminal when the target terminal resides in the 4G network.

[0075] In the case of 4G network and 5G network switching event, it indicates that the target terminal moves from the 5G weak coverage range to the 5G strong coverage range, or the target terminal moves from the 5G strong coverage range to the 5G weak coverage range. When the target terminal resides in the 4G network, the target terminal can report the 4G measurement information (including 4G MR and MDT) through the 4G network. When the target terminal resides in the 5G network, the target terminal can also report the 5G measurement report (i.e. 5G MR) through the 5G network. At this time, the 4G measurement information and the 5G measurement report are reported respectively. The terminal tag and the timestamp information in each 4G measurement information and 5G measurement report are matched based on the terminal tag and the timestamp information in the 5G MR in the 4G positioning information database constructed based on the 4G MR / MDT (4G measurement information), so that the positioning information of the 5G signal can be obtained. The 4G positioning information database can include the terminal tag, the timestamp information and the positioning information of the 4G signal.

[0076] Alternatively, in another possible implementation, the network device can also directly match the data in the 4G measurement information based on the terminal tag and the timestamp information in the 5G MR to obtain the corresponding positioning information of the 5G signal.

[0077] Optionally, the network device can obtain the 5G measurement report reported by the target terminal at the target time point by interacting with the 5G base station.

[0078] In a possible implementation, in the case that the target terminal is switched from the 5G network to the 4G network, the target time point is the last time point when the target terminal resides in the 5G network.

[0079] Figure 5 A schematic diagram of the case that the 5G network is switched to the 4G network is shown as shown in FIG. 1. Figure 5As shown, when the target terminal is handed over from the 5G network to the 4G network, there is a handover time point 510, at which the location of the target terminal is the boundary point between the strong coverage range of the 5G signal and the weak coverage range of the 5G signal, and therefore, the terminal tag and the timestamp information in the 5G measurement report reported by the target terminal at the last time point of camping on the 5G network can be acquired, the positioning information matching is performed in the 4G positioning information library, the positioning information of the location of the target terminal at the handover time point 510 is obtained, and the positioning information of the 5G signal is determined.

[0080] In the case where the target terminal is handed over from the 4G network to the 5G network, the target time point is the first time point of camping on the 5G network by the target terminal.

[0081] Figure 6 A schematic diagram of the case where the 4G network is handed over to the 5G network is shown according to an example embodiment of the present application, as shown in Figure 6 As shown, when the target terminal is handed over from the 4G network to the 5G network, there is a handover time point 610, at which the location of the target terminal is the boundary point between the weak coverage range of the 5G signal and the strong coverage range of the 5G signal, and therefore, the terminal tag and the timestamp information in the 5G measurement report reported by the target terminal at the first time point of camping on the 5G network can be acquired, the positioning information matching is performed in the 4G positioning information library, the positioning information of the location of the target terminal at the handover time point 610 is obtained, and the positioning information of the 5G signal is determined.

[0082] In a possible implementation, the process of acquiring the positioning information of the 5G signal based on the terminal tag and the timestamp information contained in the 5G measurement report and performing the positioning information matching in the 4G positioning information library can be implemented as follows:

[0083] Acquiring target positioning information in the 4G positioning information library based on the terminal tag and the timestamp information contained in the 5G measurement report, the target positioning information being the positioning information of the 4G signal of the target terminal in a target time period; the target time period being a time period determined based on the target time point;

[0084] Determining the positioning information of the 5G signal at the target time point based on the target positioning information.

[0085] Since there is a certain time difference between the 4G network and the 5G network switching, when the positioning information matching is performed through the timestamp information in the 5G measurement report, the target time period determined based on the target time point and the time difference can be obtained first, and the positioning information of the 4G signal in the target time period (i.e., the target positioning information) is obtained, and then the positioning information of the 5G signal at the target time point is determined from the target positioning information based on the terminal tag in the 5G measurement report; wherein the value of the time difference can be set by relevant personnel based on actual needs, generally, the value of the time difference is less than 5 seconds; for example, if the target terminal (assuming that the terminal tag of the target terminal is 1111111) resides in the 5G network, due to network signal or network quality reasons, it needs to reside in the 4G network, the target terminal reports the last 5G MR through the 5G network at 19:00:01, the 5G MR carries 5G related network data, and the target terminal has resided in the 4G network at 19:00:04 and reported the first 4G MR / MDT through the 4G network; if the value of the time difference is 5, the target time period is determined as 19:00:01-19:00:06, and the target positioning information corresponding to the terminal tag 1111111 is obtained from the positioning information of the 4G signal in the 4G MR / MDT reported by the target terminal within 19:00:01-19:00:06; since the target terminal resides in the 4G network at 19:00:04 and starts to report the 4G MR / MDT within the time period of 19:00:01-19:00:06, the network device can obtain the target positioning information corresponding to the terminal tag 1111111 from the positioning information of the 4G signal in the 4G MR / MDT reported by the target terminal within 19:00:04-19:00:06; then, the positioning information of the 5G signal at the target time point (i.e., 19:00:01) is determined based on the target positioning information.

[0086] Optionally, when the positioning information of the 5G signal at the target time point is determined based on the target positioning information, the method further comprises:

[0087] In the case that the error between each positioning information of the 4G signal within the target time period is less than the error threshold, the positioning information of the 5G signal at the target time point is determined based on each positioning information in the target positioning information;

[0088] In the case that the error between each positioning information of the 4G signal within the target time period is greater than the error threshold, the positioning information of the 4G signal at the time point closest to the target time point within the target time period is determined as the positioning information of the 5G signal at the target time point.

[0089] That is, if the error between the positioning information of the 4G signal in each 4G measurement information reported by the target terminal is less than the error threshold in the target time period, it indicates that the position of the target terminal changes less in the target time period, and the positioning information of the 4G signal is consistent by default. At this time, the target positioning information can be determined as the positioning information of the 5G signal at the target time point. Illustratively, when the target positioning information is determined as the positioning information of the 5G signal at the target time point, the average result of the positioning information of the 4G signal in the target time period can be determined as the positioning information of the 5G signal at the target time point, or a randomly obtained positioning information of the 4G signal in the target time period can also be determined as the positioning information of the 5G signal at the target time point.

[0090] If the error between the positioning information of the 4G signal in each 4G measurement information reported by the target terminal is greater than the error threshold in the target time period, it indicates that the position of the target terminal changes greatly in the target time period. At this time, the positioning information of the 4G signal corresponding to the time point closest to the target time point in the target time period is closest to the position of the target terminal at the target time point, so the positioning information of the 4G signal at the time point closest to the target time point in the target time period can be determined as the positioning information of the 5G signal at the target time point.

[0091] It should be noted that when the target time period is determined based on the target time point, if the 4G network and 5G network switching event is from 4G network to 5G network, the target time period is determined based on the time difference, and the target time point is the starting point, and the time period is determined forwardly. If the 4G network and 5G network switching event is from 5G network to 4G network, the target time period is determined based on the time difference, and the target time point is the starting point, and the time period is determined backwardly, so as to achieve the purpose of obtaining the positioning information of the 4G signal in the target time period.

[0092] Figure 7 A schematic diagram of 4G measurement information and 5G measurement report is shown according to an example embodiment of the present application, as shown in Figure 7 As shown, the 4G measurement information 710 includes timestamp information 711 and terminal label 712, and also includes the positioning information 713 of the 4G signal, i.e. the longitude and latitude information; the 5G measurement report 720 includes timestamp information 721 and terminal label 722, therefore, through the corresponding relationship between the timestamp information and the terminal label between the 4G measurement information and the 5G measurement report, the association between the 4G measurement information and the 5G measurement report can be realized, and the positioning information of the 5G signal can be matched from the 4G measurement information.

[0093] In step 340, the weak coverage range of the 5G signal is determined based on the positioning information of the 5G signal.

[0094] The network device can determine the weak coverage range of the 5G signal based on the positioning information of the 5G signal obtained when the target terminal resides in the 4G network.

[0095] The method for determining the signal coverage range provided in the present application can be applied to various scenarios for determining the weak coverage range of the 5G signal, such as determining the weak coverage range of the 5G signal in the scenarios of urban trunk roads, towns, buildings, etc. When the method for determining the signal coverage range provided in the present application is applied to the scenario for determining the indoor 5G signal coverage range, the process can be implemented as follows:

[0096] Obtaining map information;

[0097] Determining a target 5G signal according to the positioning information of the 5G signal and the map information; the target 5G signal is a 5G signal within an indoor range;

[0098] Determining the weak coverage range of the 5G signal within the indoor range based on the positioning information of the target 5G signal.

[0099] The map information can be the map information of a 3D high-definition map, or the map information of an electronic map, and the map information can include the positioning information of various buildings.

[0100] Based on the positioning information of various buildings, the obtained 5G signal can be screened to distinguish the indoor 5G signal from the outdoor 5G signal, so as to determine the 5G signal distributed in the geographical range of each building, i.e., to determine the target 5G signal; and then based on the positioning information of the target 5G signal, the weak coverage range of the 5G signal within the indoor range is determined.

[0101] In another possible implementation, in order to further improve the accuracy of indoor range positioning, on the premise of determining the indoor range through the map information, the user's historical behavior data can also be obtained on the premise of obtaining the user's authorization, the historical behavior data is analyzed to obtain the user features; the indoor feature database and the outdoor feature database are respectively constructed based on the difference between the user features and the signal features in the indoor and outdoor scenarios in combination with the user features and the signal features; the user features can include call features, service features, and movement features, etc.; the signal features can include level features, neighbor cell features, handover features, and cell features, etc. For the level features, the signals are strong because of the directivity in the outdoor, while the signals are weak because of the loss of signal penetration through the buildings in the indoor. For the movement features, the user is in the driving, riding, or walking state in the outdoor, so the user has mobility, while the user is in the stationary state in the indoor, so the user has low mobility.

[0102] In summary, the method for determining the signal coverage range provided by the embodiments of the present application utilizes the feature that the 4G network can collect position information, and makes the 5G terminal contain both 4G measurement information and 5G signal information in the measurement report reported through the 4G network, and the 4G measurement information contains the positioning information of the 4G signal, so that the positioning information of the 5G signal can be determined based on the measurement report, and the weak coverage range of the 5G signal can be determined based on the positioning information of the 5G signal in the case that the target terminal resides in the 4G network. Through the above method of filling the positioning information of the 5G signal based on the 4G inter-system measurement report, the 5G weak coverage range can be determined in real time, the dynamic detection of the 5G weak coverage range is realized, and thus the determination effect of the 5G weak coverage range is improved.

[0105] Way 2: In the case that the target terminal exists between the 4G network and the 5G network, the terminal tag and the timestamp information are obtained through the 5G MR reported by the target terminal before or after the switching, and in the data matching and association analysis, the positioning information of the 5G signal at the switching moment is determined from the 4G positioning information database according to the terminal tag and the timestamp information.

[0106] The way of determining the positioning information of the 5G signal at the switching moment in the way 2 is a supplement to the way of obtaining the positioning information of the 5G signal in the way 1, and the 5G positioning information database is constructed based on the positioning information of the 5G signal obtained by the above two ways.
