Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method and apparatus for evaluating the building depth coverage effect of macro base stations. Background Technology

[0002] In wireless network planning, the coverage effect of outdoor macro base stations inside buildings (or indoors) is often difficult to evaluate. This is because in existing systems, the network coverage level of the terminal's location can be evaluated based on measurement report data based on the latitude and longitude information carried by the terminal. However, inside buildings, the terminal's GPS signal is usually weak, making it easy to lose this data, thus making it impossible to evaluate indoor coverage.

[0003] The existing solution mainly uses actual traversal testing for evaluation, that is, a person holds a test terminal and leaves the terminal at an outdoor macro base station to traverse the interior of the building, test its RSRP / SINR / uplink and downlink rates and other indicators, and combine the on-site map to visualize and statistically analyze the data sampling points, thereby evaluating the building depth coverage effect of the macro base station.

[0004] The existing technical solutions have the following drawbacks: they are performed manually, which is inefficient and costly; and they have accessibility issues within buildings, such as traversing unreachable areas like rooms, which leads to distorted test results. Summary of the Invention

[0005] This invention provides a method and apparatus for evaluating the building depth coverage effect of macro base stations, which solves the defects of low efficiency and distorted test results in the existing technology where the evaluation of the indoor coverage effect of macro base stations is performed manually.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0044] In this invention, a base station may be referred to as a Node B, Evolved Node B (eNB), Access Point, Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home B Node, Home Evolved B Node, Transmitting Receiving Point (TRP), or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms.

[0045] In this invention, the terminal can be a mobile phone, tablet computer, laptop computer (also called a notebook computer), personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), etc. Wearable devices include smartwatches, smart bracelets, smart headphones, smart glasses, etc. It should be noted that the specific type of terminal is not limited in the embodiments of this invention.

[0046] The following is combined Figures 1-5 This invention describes a method and apparatus for evaluating the building depth coverage effect of a macro base station.

[0047] Figure 1This is one of the flowcharts illustrating the building depth coverage effect evaluation method for macro base stations provided by the present invention. Figure 1 As shown, the method for evaluating the building depth coverage effect of macro base stations, when applied to terminals, includes the following steps:

[0048] Step 100: Periodically send measurement instructions to the terminal residing in the indoor base station of the building and configure parameters. The measurement instructions are used to instruct the terminal to measure the reference signal received power RSRP of the outdoor base station cell that is in the same system or a different system as the indoor base station of the building.

[0049] For the planning and deployment of new standards (such as 5G / 6G), new frequency bands (such as the newly licensed 5G spectrum 2.6G / 3.5G / 4.9G), and new equipment (such as Massive MIMO AAU equipment), whether to carry out indoor network construction requires an assessment of whether the outdoor macro base stations of the network can achieve good indoor coverage.

[0050] Considering existing networks, such as 2G / 3G / 4G wireless networks, after years of construction, indoor base stations of this standard have been basically built for areas with poor outdoor base station coverage or important buildings. Therefore, users who are stationed at indoor base stations can be basically determined to be located inside the building.

[0051] This invention proposes a method to send measurement commands from an existing indoor base station (such as a 4G indoor base station) to a different system (such as 5G) and configure relevant parameters, so that the terminal residing at the indoor base station can report the coverage level of a certain frequency band of the same / different system (such as 5G 3.5G / 2.6G outdoor / indoor frequency bands, or 4G 2.6G / 1800M outdoor / indoor frequency bands).

[0052] In this embodiment of the invention, the indoor base station cell in a building periodically sends measurement commands and configures parameters to terminals residing in the indoor base station. These measurement commands are commands to measure the RSRP of outdoor base station cells within the same or different systems.

[0053] The RSRP of outdoor base station cells corresponds to the operating frequency band. Measuring the RSRP of outdoor base station cells in the same or different systems can also be understood as measuring the RSRP of the same or target frequency bands of the system.

[0054] "Same system" means that the outdoor base station has the same system as the indoor base station, but the outdoor base station and the indoor base station operate on different frequencies. For example, they can both be 4G systems, but operate on different frequency bands.

[0055] Different systems refer to outdoor base stations having different systems than indoor base stations. For example, an indoor base station is a 4G base station, while an outdoor base station is a 5G macro station.

[0056] It should be noted that outdoor base stations can also be called macro base stations or macro stations.

[0057] Step 101: Receive the measurement report reported by the terminal, the measurement report including the RSRP value of the outdoor base station cell;

[0058] The indoor base station cell receives the measurement report reported by the terminal and obtains the RSRP value of the outdoor base station cell.

[0059] Step 102: Perform data cleaning on the RSRP value of the outdoor base station cell to obtain the effective RSRP value of the outdoor base station cell;

[0060] After data cleaning and processing, the effective RSRP value of the outdoor base station cell is output.

[0061] Step 103: Evaluate the deep coverage effect of the outdoor base station cell on the building based on the effective RSRP value of the outdoor base station cell.

[0062] Furthermore, based on the effective RSRP value of the outdoor base station cell, a quantitative assessment of the coverage effect of a certain frequency band in the same or different system of the building where the indoor base station is located can be obtained.

[0063] Optionally, the deep coverage effect of the outdoor base station cell on the building includes at least one of the following: the overall indoor coverage effect of the outdoor base station cell on the building, the indoor coverage effect of a single outdoor base station cell on the building, and the indoor coverage rate of the building by the combined or single outdoor base station cells.

[0064] For example, a building may have an E-band 4G indoor base station deployed, but no 5G indoor base station. To assess whether a 5G indoor base station is needed and the required area for its construction, it's necessary to evaluate the coverage effect of a 5G outdoor base station (e.g., 5G 2.6G / 3.5G / 700M bands) on the building. By sending measurement commands from the 4G indoor base station to instruct terminals residing there to report the signal level of the 5G outdoor base station, and processing the data accordingly, the indoor coverage effect of the macro base station can be evaluated, providing a reference for whether or not to build an indoor base station and the area required for its construction.

[0065] In this embodiment of the invention, periodic same / different system measurement commands with customized configuration parameters are issued by the existing indoor base station system, enabling the terminal stationed at the indoor base station to report RSRP measurement data of the outdoor base station cell. Through data cleaning and calculation, the macro base station coverage effect of the building where the indoor base station is located is evaluated. This method does not rely on on-site manual testing, which improves the efficiency of macro base station indoor coverage evaluation, reduces evaluation costs, and improves the accuracy of macro base station indoor coverage effect evaluation because it is based on network data acquisition.

[0066] Optionally, measurement commands are periodically sent to terminals residing in indoor base stations of buildings and parameters are configured. The total duration of the measurement command sending is denoted as T.

[0067] Optionally, the parameter configuration includes:

[0068] 1) Set the threshold for initiating periodic measurement reports and reporting to the lowest value allowed by the system corresponding to the indoor base station of the building;

[0069] For example, for 5G systems, the minimum allowable value for measurement reporting is -156dBm.

[0070] The purpose of setting the threshold for initiating measurement and reporting periodic measurement reports to the lowest value is to collect all samples residing at the indoor base station and avoid losing samples with low RSRP levels.

[0071] 2) Set the reselection / handover threshold triggered by the A4 / B1 event to the maximum value allowed by the system corresponding to the indoor base station of the building.

[0072] The definitions of A4 / B1 events are consistent with those in 3GPP 36.331 5.5.4. An A4 event with better neighboring cells within the same system than a certain threshold is denoted as Th_A4, and a B1 event with better neighboring cells across different systems than a certain threshold is denoted as Th_B1. For example, for a 5G system, Th_B1 is set to -31dBm.

[0073] The purpose of setting the reselection / handover threshold triggered by the A4 / B1 event to the maximum value is to collect all samples residing in the indoor base station and avoid sample loss at high RSRP levels.

[0074] In this embodiment of the invention, by configuring parameters, the loss of samples at both low and high RSRP levels can be avoided, thereby obtaining all measurement data residing in the indoor base station. The data is highly available and reliable, thus ensuring the accuracy of the evaluation of the indoor coverage effect of the macro base station.

[0075] Optionally, the step of cleaning the RSRP value of the outdoor base station cell to obtain the effective RSRP value of the outdoor base station cell includes:

[0076] The RSRP values ​​of the outdoor base station cell are cleaned by short-term invalid data cleaning and long-term fixed-point duplicate data cleaning to obtain the effective RSRP values ​​of the outdoor base station cell.

[0077] In this embodiment of the invention, by performing short-term invalid data cleaning and long-term fixed-point duplicate data cleaning on the RSRP value of the outdoor base station cell, the measurement data of terminals that stay for a very short time and the measurement data repeatedly reported at the same geographical point can be filtered out, so that the measurement data used for macro base station indoor coverage effect evaluation is valid and reliable, thereby improving the accuracy of macro base station indoor coverage effect evaluation.

[0078] Furthermore, the short-term invalid data cleaning of the RSRP value of the outdoor base station cell includes:

[0079] Based on the characteristics of the building and user groups, an effective data collection time threshold is determined, and the RSRP value of the outdoor base station cell is cleaned of invalid data for a short period of time based on the effective data collection time threshold.

[0080] The long-term fixed-point repetitive data cleaning of the RSRP value of the outdoor base station cell includes:

[0081] The terminal measurement sampling points are arranged in a time sequence. If the RSRP value between the current measurement sampling point and the previous adjacent measurement sampling point is less than the level fluctuation step size, the RSRP value of the current measurement sampling point is discarded.

[0082] Assume that within the total measurement duration T, the indoor base station issues a measurement command once every T_period, for a total of K_Max measurement commands. Let the nth terminal camped on the indoor base station receive the kth measurement command from the mth cell of the indoor base station, measure the RSRP of the lth cell of the same / different system outdoor base station (assuming there are L outdoor base station cells in total), and report it to the indoor base station. Let the RSRP sample value be RSRP. n_m_k_l The sample data underwent the following cleaning process:

[0083] 1) Cleaning short-term invalid data

[0084] Let the effective data sampling time threshold be T_effect. If the data sample size reported by a terminal is Num_report, and if Num_report*T_period / L < T_effect, then the data reported by the terminal is invalid and will not be retained.

[0085] T_effect refers to the duration of the terminal's stay in the indoor cell, which can be adjusted based on the characteristics of the building and user group. The purpose is to filter out samples with extremely short stay times, thereby introducing samples with overly good coverage (such as users who pass through the building and stay in the indoor cell for a short time).

[0086] 2) Long-term fixed-point data cleaning

[0087] If the same terminal stays in the same location for a long time, it will repeatedly report data from the same geographical location, causing data deviation. Therefore, duplicate data reports from the same geographical location should be identified and discarded.

[0088] Let the level fluctuation step size for determining stillness be Move_Gap_RSRP. When arranging the timing of measurement sampling points for a given terminal, if the RSRP value between the current measurement sampling point and the previous adjacent measurement sampling point is less than the level fluctuation step size, i.e., RSRP... n_m_k_l -RSRP n_m_k-1_l <Move_Gap_RSRP, then for RSRP n_m_k_l Discard the samples and retain only the earlier time series samples.

[0089] The level fluctuation step size, Move_Gap_RSRP, can be adjusted according to the degree of obstruction inside the building, and can be set to 1.5dB by default. If the interior is spacious, increase this value; if there are many partitions inside, decrease this value.

[0090] Optionally, evaluating the deep coverage effect of the outdoor base station cell on the building based on the effective RSRP value of the outdoor base station cell includes at least one of the following:

[0091] The indoor comprehensive coverage effect of the outdoor base station cell on the building is evaluated based on the effective RSRP value of the outdoor base station cell;

[0092] The indoor coverage effect of a single outdoor base station cell on the building is evaluated based on the effective RSRP value of the outdoor base station cell.

[0093] The indoor coverage rate of the building by the combined or single outdoor base station cell is calculated based on the effective RSRP value of the outdoor base station cell.

[0094] The effective sample value after data cleaning is RSRP_ef n_m_k_l If there are a total of Num_all samples, then the number of effective indoor samples is Num_effect = Num_all / L, where L is the number of outdoor base station cells.

[0095] 1) Evaluation of the indoor comprehensive coverage effect of the outdoor base station cell on the building

[0096] For a valid RSRP sample reported by the nth terminal in the kth measurement obtained from the mth indoor base station, multiple outdoor base station RSRPs should be measured, and the sample with the maximum value should be taken, i.e.:

[0097] RSRP_ef = RSRP_ef_max n_m_k =MAX(RSRP_ef n_m_k_l RSRP_ef n_m_k_l-1,..)

[0098] For example, if L = 3 (meaning the building can receive signals from 3 macro base station cells), and after receiving the sampling command, the terminal measures the RSRP of the 3 outdoor base station cells as -98dBm, -112dBm, and -156dBm, then RSRP_ef = RSRP_ef_max n_m_k = -98dBm.

[0099] 2) Evaluation of the indoor coverage effect of a single outdoor base station cell on the building

[0100] For a valid RSRP sample reported by the nth terminal in the kth measurement from the mth indoor base station, multiple outdoor base station RSRPs should be measured. For the target outdoor base station cell (denoted as l), only its relevant data are extracted, i.e.:

[0101] RSRP_ef = RSRP_ef n_m_k_l

[0102] For example, if L=3, after the terminal receives the sampling command, the RSRP of the 1st, 2nd and 3rd macro base station cells are measured to be -98dBm, -112dBm and -156dBm respectively. If it is desired to evaluate the coverage effect of the 2nd outdoor base station cell on the indoor environment, then RSRP_ef=-112dBm.

[0103] 3) Calculation of indoor coverage rate of the building by a combined or single outdoor base station cell.

[0104] Set the RSRP value of the outdoor base station to the indoor target coverage value to RSRP_Target. If RSRP_ef > RSRP_Target, then increment the count of the number of qualified indoor sample level samples Num_qualified (initially 0) by 1.

[0105] For the full RSRP_ef n_m_k_l Perform either the above-mentioned operation 1) evaluating the overall indoor coverage effect of an outdoor base station cell on the building, or 2) evaluating the indoor coverage effect of a single outdoor base station cell on the building, to obtain the total number of qualified macro base station samples, Num_qualified. Then, the indoor coverage rate of the building by the overall or single outdoor base station can be calculated as: C_macro2indoor = Num_qualified / Num_effect.

[0106] In particular, for scenarios where m indoor base station cells cover different floors of a building, the above processing can be performed on each of the m indoor base station cells individually to evaluate the indoor coverage effect of outdoor base stations on different floors.

[0107] In this embodiment of the invention, a periodic same / different system frequency measurement command with customized configuration parameters is issued by an existing indoor base station system, enabling the terminal residing in the indoor base station system to report target system, cell, and frequency band RSRP measurement data. Through data cleaning and calculation, the macro base station coverage effect of the building where the indoor base station is located is evaluated. This method does not rely on on-site manual testing, improves the efficiency of macro base station indoor coverage evaluation, reduces evaluation costs, and can achieve macro base station indoor coverage effect evaluation from multiple aspects, thus improving the comprehensiveness and accuracy of macro base station indoor coverage effect evaluation.

[0108] Figure 2 This is the second flowchart illustrating the method for evaluating the building depth coverage effect of a macro base station according to an embodiment of the present invention. Figure 2 As shown, the method includes the following steps:

[0109] Step 200: Receive measurement instructions periodically issued by the indoor base station cell of the building, wherein the measurement instructions are used to instruct the measurement of the reference signal received power RSRP of the outdoor base station cell which is in the same system or a different system as the indoor base station of the building;

[0110] Step 201: Measure the RSRP of the outdoor base station cell and report the measurement report to the indoor base station of the building. The measurement report includes the RSRP value of the outdoor base station cell.

[0111] It is understood that the terminal receives measurement instructions periodically issued by the indoor base station cell of the building. The measurement instructions are used to instruct the terminal to measure the reference signal received power (RSRP) of the outdoor base station cell, which is in the same system or a different system as the indoor base station of the building. The terminal measures the RSRP of the outdoor base station cell and reports a measurement report to the indoor base station of the building. The measurement report includes the RSRP value of the outdoor base station cell.

[0112] The understanding of the measurement instructions can be found in the description in the foregoing embodiments, and will not be repeated here.

[0113] In this embodiment of the invention, the terminal residing in the indoor base station cell receives periodic same / different system measurement instructions with customized configuration parameters issued by the established indoor base station system, performs measurement operations, and reports the RSRP measurement data of the outdoor base station cell to the indoor base station. Subsequently, through data cleaning and calculation, the macro base station coverage effect of the building where the indoor base station is located is evaluated. This invention does not rely on on-site manual testing, improves the efficiency of macro base station indoor coverage evaluation, reduces evaluation costs, and improves the accuracy of macro base station indoor coverage effect evaluation because it is based on network data acquisition.

[0127] Optionally, the short-term invalid data cleaning of the RSRP value of the outdoor base station cell includes:

[0128] Based on the characteristics of the building and user groups, an effective data collection time threshold is determined, and the RSRP value of the outdoor base station cell is cleaned of invalid data for a short period of time based on the effective data collection time threshold.

[0129] The long-term fixed-point repetitive data cleaning of the RSRP value of the outdoor base station cell includes:
