Description

Anchor point station determining method, device, equipment and readable medium based on NSA mode

Technical Field

The embodiment of the invention relates to the technical field of wireless networks, in particular to an anchor point station determining method, device, equipment and readable medium based on an NSA mode.

Background

At present, when a Next Generation CORE (NGC) of a fifth Generation mobile communication technology (5th Generation mobile networks, 5G) is not ready, in order to implement rapid deployment of a 5G new air interface (5GNew Radio, 5GNR), operators preferentially adopt a Non-independent Networking (NSA). In the NSA mode, when 5G provides wireless access service to the ue, the ue needs to use the 4th Generation mobile communication technology (4G) base station.

Specifically, the NSA needs to use a current 4G core network and a 4G base station, and uses the current 4G base station as an anchor point of a control plane, so as to meet a requirement that an operator uses a current Long Term Evolution (LTE) network resource to implement rapid deployment of the 5 GNR. The NSA mainly aims at improving network bandwidth of a hot spot area, and still needs to work by relying on a 4G base station and a core network because a non-independent networking does not have an independent signaling plane. To implement NSA, first, the number, position, frequency band, and other configuration related parameters of anchor sites in a target area need to be planned.

Currently, in the current technology, a lot of data needs to be collected and analyzed manually when site planning is performed for an anchor point. The problem with this is that: on one hand, great manpower and material resources are required to be input when anchor point planning is carried out, the whole planning consumes long time and is not suitable for large-scale rapid planning and station building, on the other hand, manual testing is mainly carried out by outdoor road testing, data samples have space limitation and selectivity, indoor coverage samples are difficult to obtain, and errors exist in analysis of coverage performance. These result in inefficient and costly anchor point planning and determined anchor point site locations that are not the most efficient coverage, thereby affecting the popularity and application of 5G technology.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.

Fig. 1 shows a flow chart of an NSA mode based anchor point determination method in an embodiment, which may be implemented by means of a computer program that is executable on a computer system based on the von neumann architecture, in particular, on a computer processing device such as a mobile phone, a laptop computer, etc. As shown in fig. 1, the method comprises the following steps 110-140:

step 110: target data is obtained, wherein the target data at least comprises MR data, working parameter data of an available LTE base station and site data of a target NR base station, and the target data is preprocessed.

First, MR (Measurement Report) data is network Measurement data reported by a mobile phone, and may be reported on a periodic basis, such as every 10 minutes, or on an event basis, such as when a mobile phone network is interrupted or the quality is poor, and a signal coverage condition of a certain slice area may be determined according to MR data uploaded by each mobile phone.

Secondly, since the present invention is based on NSA, i.e. a non-independent networking mode, in the NSA mode, the 5G base station can also be used as a micro station to perform co-station or non-co-station deployment with the existing LTE base station (eNB).

And the anchor point stations are distributed around the stations such as 4G existing macro stations, indoor distribution stations, small stations and the like as transmission access points, and planning, address selection and anchoring are carried out on the station transmission access points in advance by combining the 5G layout scale.

And the future 5G base station construction is accessed according to the anchor point plan. Therefore, the target nr (new radio) base station here refers to an address of a 5G base station to be established later.

The specific working parameter data of the available LTE base station may include a base station identifier, physical structure data, an antenna position, an azimuth angle, a coverage range, and the like of each alternative 4G LTE base station.

The process of preprocessing the target data may include cleaning the target data, converting the target data into a preset data format, removing abnormal data in the original input data, and outputting the target data as usable target data.

Step 120: and determining a planning parameter threshold corresponding to the target NR base station, and determining an alternative anchor point site from the available LTE base station according to the planning parameter threshold and the preprocessed target data.

Considering that the anchor point station has the function of realizing the intermediate transition from the 4G signal to the 5G signal, in order to realize the comprehensive coverage of the signals and simultaneously not waste the station building resources, the planning parameter threshold value of the anchor point station planning can be determined according to the current network planning condition of the anchor point station (such as the number of the existing anchor point stations in a certain reference distance range and the frequency band covered by the existing anchor point stations) and the target KPI data of the estimated 5G NR (such as the optimal signal coverage rate and/or the suboptimal signal coverage rate which should be reached).

First, the planning parameter threshold herein may include a current anchor point planning reference distance threshold, that is, an available LTE base station with a large distance from the target NR base station is selected to determine whether the LTE base station can be used as an alternative anchor point. In a specific embodiment, the determination of the current anchor point planning reference distance threshold may be determined according to the number and distribution of the current available LTE base stations, or may be input by a person related to anchor point planning.

Further, it is easily understood that, in order to determine whether a better signal coverage from an available LTE base station can be received at the current target NR site location, the planning parameter threshold further includes a first distance threshold, i.e. how far the signal coverage of the available LTE base station is obtained for judgment and screening, which may be 300 meters, for example.

Similarly, the determination of the first distance threshold may be performed by determining the number and distribution of currently available LTE base stations, or may be input by a person related to anchor station planning.

The determining alternative anchor sites from the available LTE base stations according to the planning parameter threshold and the preprocessed target data may further include

steps

1201 and 1202 shown in fig. 2. Fig. 2 illustrates a flow diagram for determining alternative anchor sites in one embodiment.

Step 1201: determining an area formed by taking the target NR station address as a circle center and the first distance threshold as a radius as a first target area, and determining whether the first target area has the available LTE base station on a preset frequency band according to the preprocessed target data, wherein the preset frequency band at least comprises a first preset frequency band and a second preset frequency band.

Since the first distance threshold is set to be small (e.g. 300 meters), and the signal coverage is generally good in a short distance, if there is an available LTE base station in the first target area around the target NR station, the detection of the signal coverage is not needed, and it is directly used as an alternative anchor point.

In addition, the preset frequency band may be a common 4G frequency band such as GSM900, GSM1800, etc. In an alternative embodiment, the preset frequency band may further include more frequency bands.

Step 1202: when the available LTE base station exists in the first target area, determining the available LTE base station existing in the first target area as the alternative anchor point site.

In practical application, there may be a case where there is no available LTE base station in the first target area, in this case, the signal detection range may be further expanded, it is determined whether there is an available LTE station around the target NR station within a larger range, and in the case where there is an available LTE station, detection is further performed with respect to the signal coverage (different from the case where there is a signal within the first area that is generally better covered due to a closer distance, and the existing available LTE base station may be directly used as an alternative anchor point), and a suitable LTE station is determined to be used as an alternative anchor point.

Thus, in an optional embodiment, the planning parameter threshold further comprises a second distance threshold, a first coverage threshold, a second coverage threshold, and the second distance threshold is greater than the first distance threshold.

Specifically, the first coverage threshold may be understood as a lower optimal signal coverage limit of the anchor station, such as 98%, and the second coverage threshold may be understood as a lower sub-optimal signal coverage limit of the anchor station, such as 95%;

correspondingly, the second distance threshold may be understood as that, in the case that no suitable available LTE station exists in the first target area, the signal coverage of the available LTE base station in the farther distance range is further obtained for judgment and screening, and may be set to 500 meters (greater than the first distance threshold by 300 meters), for example.

After determining whether there is an available LTE base station with a preset frequency band in the first target area according to the preprocessed target data, the method further includes step 1211-1217 shown in fig. 3, where fig. 3 shows a flowchart of determining an alternative anchor site when there is no LTE base station with the preset frequency band in the first target area in an embodiment.

Step 1211: and when the LTE base station of the preset frequency band does not exist in the first target area, determining an area formed by taking the target NR station address as a circle center and the second distance threshold as a radius as a second target area.

Continuing with the foregoing example, the first distance threshold may be 300 meters and the second distance threshold may be 500 meters, the first coverage threshold may be 70%, and the second coverage threshold may be 50%. (example of second target region referring to FIG. 2)

Step 1212: determining whether the available LTE base station exists in the preset frequency band outside the first target area and inside the second target area, and determining the signal coverage rate of the available LTE base station on the preset frequency band outside the first target area and inside the second target area as a first signal coverage rate according to the preprocessed target data under the condition that the available LTE base station exists in the preset frequency band outside the first target area and inside the second target area.

Referring to the schematic diagram of fig. 4, fig. 4 shows a schematic diagram of a first target area and a second target area in an embodiment, where L1 is the first target area, and L2 is the second target area, that is, there is no directly available LTE base station in a relatively close L1 range, and a screening of signal coverage is performed for an available LTE base station outside L1 but in an L2 range.

Step 1213: and comparing the first signal coverage rate with the first coverage rate threshold, and when the first signal coverage rate is greater than the first coverage rate threshold, taking the available LTE base station corresponding to the first signal coverage rate as the alternative anchor point site.

The description is made with reference to step 1212-1213, that is, the coverage rate of each available LTE base station at the target NR base station site is determined according to the MR data and the working parameter data of the available LTE base station, and if the coverage rate can reach the first signal coverage rate, it can be considered that if an anchor station is established at the available LTE base station by the same station, the signal of the anchor station can cover the target NR base station site, so that the available LTE base station in the second target area can be used as the alternative anchor station.

Step 1214: and when the coverage rate of the first signal is smaller than the second coverage rate threshold, determining the alternative anchor point site according to the target NR site according to a preset corresponding relation.

In connection with step 1213, there is an available LTE base station in L2 but its signal coverage at the target NR base station site cannot meet the lowest signal coverage for direct station establishment, so it is necessary to select a supplementary station establishment and prioritize the co-station between the anchor station and the 5G base station to be established later. Therefore, the alternative anchor point site is determined according to the target NR site according to the preset corresponding relation.

Step 1215: and when the first signal coverage rate is not greater than the first coverage rate threshold and not less than the second coverage rate threshold, performing a preset signal optimization operation on the areas outside the first target area and inside the second target area, and acquiring the signal coverage rates of the preset frequency bands of the areas outside the first target area and inside the second target area after the signal optimization operation as second signal coverage rates.

It is easy to understand that when the existing available LTE base station is located between coverage areas where direct station establishment is possible and where station establishment is not possible, there is a certain potential for station establishment, and therefore signal optimization can be performed on the existing available LTE base station first, and specific signal optimization operations may be adjusting an antenna angle, determining whether a coverage object exists, clearing a signal transmission obstacle, and the like by executing a preset program.

After the signal optimization operation is completed, the judgment of whether the optimized signal coverage rate meets the threshold value can be carried out again, so that the secondary check can ensure that the existing resources are not wasted.

Step 1216: and comparing the second signal coverage rate with the first coverage rate threshold, and when the second signal coverage rate is greater than the first coverage rate threshold, taking the available LTE base station corresponding to the second signal coverage rate as the alternative anchor point site.

Step 1217: and when the second signal coverage rate is smaller than the first coverage rate threshold value, determining the alternative anchor point site according to the target NR site.

That is, if the optimized signal coverage is still smaller than the lower limit of the optimal coverage of the anchor point station, that is, there is no existing available LTE base station that can be used as the anchor point station, so an anchor point station needs to be newly established according to the target NR station address, and optionally, the anchor point station and the NR station can be considered together.

It is easy to understand that after determining that there is a currently available LTE base station that can be used as an alternative anchor station, it may further determine which anchor stations on which frequency bands need to be performed and how many anchor stations need to be established to meet the needs, and therefore step 130 may also be included.

Step 130: and determining the target frequency band to be planned and the number of target anchor points.

In consideration of the signal coverage and mediation functions of the anchor point stations, in order to reduce inter-frequency handover between anchor point stations, the frequency band coverage condition of the current anchor point station within a certain range of the alternative anchor point station can be referred to when determining the frequency band of the alternative anchor point station, and more frequency bands of the current anchor point station covered on the frequency band are taken as the target frequency bands to be planned.

Similarly, when determining how many anchor points are needed in the current target NR station address area, the setting condition of the current anchor point within a certain range of the current area may also be referred to, that is, how many anchor points are set on the average level may meet the requirements of signal transmission and coverage.

In summary, the specific process of determining the target planned frequency band may include at least steps 1301 to 1302 shown in fig. 5. Fig. 5 shows a flow chart of the determination of the target planning frequency band in one embodiment.

Step 1301: acquiring a planning reference distance set value, comparing the planning reference distance set value with the first distance threshold, determining an area with a distance less than or equal to the planning reference distance set value from the target NR base station as a planning reference area under the condition that the planning reference distance set value is less than the first distance threshold, and acquiring the number of current anchor point stations on the preset frequency band in the planning reference area.

First, the planning reference distance setting value here is similar to the planning reference distance threshold of the current anchor point in the planning parameter thresholds in step 120, that is, the situation of the current anchor point which is more distant from the target NR base station is selected for reference. In a specific embodiment, the determination of the planning reference distance value may be determined according to the number and distribution of the currently available LTE base stations, or may be input by a person related to the anchor station planning.

The determination of the planning reference distance set value enables the average planning number of anchor point stations in the actual nearby area to be referred to, so that waste is avoided, and the requirement can be met.

Furthermore, when the planning reference distance setting value is smaller than the first distance threshold, the number of the anchor point stations in the area within the current planning reference distance setting value in each preset frequency band may be directly obtained without further consideration of the signal coverage rate in each frequency band (since a closer area is defined when the distance is smaller than the first distance threshold, the signal coverage is better by default).

Step 1302: comparing the number of current anchor points on each preset frequency band, and determining the preset frequency band with the maximum number of current anchor points as the target frequency band to be planned.

That is, to avoid frequency band switching too frequently, a plurality of frequency bands with the largest number of existing anchor sites may be directly selected as the target frequency band.

It is easy to understand that the distance between the existing available LTE base station and the target NR base station exceeds the planned reference distance setting value, because due to the increase of the reference distance, even if there are a sufficient number of anchor stations, it is not always possible, and therefore it is further necessary to consider the coverage rate of each frequency band as a whole, and therefore, the determination is performed according to the coverage rate of each frequency band.

After comparing the planning reference distance setting value with the first distance threshold, the method further includes steps 1311 and 1313 shown in fig. 6, where fig. 6 shows a flowchart for determining a target frequency band to be planned in another embodiment.

Step 1311: and under the condition that the planning reference distance set value is greater than or equal to the first distance threshold, acquiring and comparing the signal coverage rate of the planning reference area on the preset frequency band, and determining the difference value of the signal coverage rate on each preset frequency band.

Step 1312: and when the difference value of the signal coverage rate on each preset frequency band is greater than or equal to a preset coverage rate difference threshold value, determining the preset frequency band with the highest signal coverage rate as the target frequency band to be planned.

That is, when the signal coverage rate between the preset frequency bands is greatly different, in order to reduce the pilot frequency switching of the anchor point station, the frequency band with the largest signal coverage rate is directly obtained as the target frequency band to be planned.

Step 1313: and when the difference value of the signal coverage rate on each preset frequency band is smaller than the preset coverage rate difference value threshold value, acquiring the preset frequency band with the maximum number of current anchor point sites as the target frequency band to be planned.

That is, when the difference value of the signal coverage rates on the preset frequency bands is smaller than the preset coverage rate difference value threshold, because the distance between the reference range of the current surrounding anchor point station and the target NR station is short, the signal coverage rate on each frequency band can be ensured, so that the factor of the signal coverage rate can be ignored, and the preset frequency band with the maximum number of current anchor point stations is directly acquired as the frequency band to be planned, thereby avoiding frequent switching of the frequency band.

The same determination regarding the number of target anchor sites is also performed with reference to the number of current anchor sites in the surrounding area of the current target NR, which may specifically include steps 1321 to 1322 shown in fig. 7, where fig. 7 shows a flowchart for determining the number of target anchor sites in an embodiment.

Step 1321: and comparing the planning reference distance set value with the first distance threshold, and determining the number of the target anchor points as 1 when the planning reference distance set value is not greater than the first distance threshold.

That is, when planning an area where the reference distance setting value is closer to the target NR station address, it is not necessary to consider how many existing anchor stations exist in the surrounding area, and the signal coverage and signal management of the target NR station can be realized by defaulting one anchor station base station.

Step 1322: and when the planning reference distance set value is larger than the first distance threshold value, acquiring the average value of the current anchor point station number as the target anchor point station number.

That is to say, when the planned reference distance setting value is an area far from the target NR station address, how many existing anchor stations are in the surrounding area is not considered, and the number of anchor stations to be added for realizing signal coverage and signal management of the target NR station is determined according to the number of existing anchor stations averagely set in the surrounding area.

Step 140: and selecting a plurality of alternative sites of the target anchor site from the alternative anchor sites as the target anchor sites on the target frequency band to be planned.

It is easy to understand that, in the case that there are multiple alternative anchor points, several anchor points with better signal coverage may be preferentially selected as the target anchor points for final field planning, and sorted in descending order of signal coverage and output to the relevant personnel.

That is, specifically, steps 1401 and 1402 shown in fig. 8 may be included, and fig. 8 shows a flowchart of outputting the target anchor site in one embodiment.

Step 1401: and determining the signal coverage rate of each alternative anchor point site on the target planning frequency band at the target NR site according to the target data, and sequencing and outputting the alternative anchor point sites according to the sequence from large to small of the signal coverage rate of each alternative anchor point site on the target planning frequency band at the target NR site.

Step 1402: and acquiring a plurality of alternative sites of a front target anchor site in the output alternative anchor site sequence as the target anchor site.
