Embodiments of the present invention have been described in connection with a network system. The network system may be a computer or other device capable of processing data.

Fig. 1 is a schematic flow chart of a method 100 for cell adjustment according to an embodiment of the present invention, where the method 100 may be executed by a network system, or may be executed by other systems or devices, for example, as shown in fig. 1, the method 100 is executed by the network system, and includes:

s110, obtaining a plurality of initial Measurement Information (MI) of at least two cells, the at least two cells including at least one cell to be adjusted and an evaluation cell corresponding to each cell to be adjusted in the at least one cell to be adjusted, wherein each initial MI of the plurality of initial MIs includes a plurality of first reception level values, and the plurality of first reception level values are in one-to-one correspondence with the plurality of cells;

specifically, if at least one cell to be adjusted is adjusted, the network system needs to obtain an initial MI of each cell to be adjusted in the at least one cell to be adjusted and an initial MI of an evaluation cell of each cell to be adjusted. The number of the plurality of initial MIs of the at least two cells is the sum of the number of initial MIs of the cell to be adjusted and the number of initial MIs of the evaluation cell. For example, the cell to be adjusted is a₁Each cell to be adjusted has an initial MI of b₁Estimating a cell as a₂Each evaluating the initial of a cellMI is b₂A plurality of initial MI of the at least two cells is a₁·b₁+a₂·b₂. Each initial MI includes a plurality of first reception level values in one-to-one correspondence with a plurality of cells. For example, assuming that the a cell is a cell to be adjusted, a first initial MI among the initial MIs of the a cell may include first reception level values of the a cell, the B cell, the C cell, the D cell, and the E cell. Alternatively, the MI may include Measurement Reports (MR), drive test data, or sweep data. The MR is an important means for the network system to obtain the wireless information of the terminal, and the network system can acquire the strength, quality and other information of the receiving level values of the plurality of cells received by the terminal equipment after receiving the MR. The MI may include various types of information, which can improve the compatibility and scalability of the method.

In an embodiment of the present invention, the reception level value of the cell included in the MI (e.g., the initial MI) may be a reception level value at which the terminal device receives the cell signal. For example, the first initial MI includes a reception level value of the a-cell may be understood as a reception level value at which the terminal device receives the a-cell signal. For simplicity, the embodiments of the present invention are described with the reception level value of the cell. The initial MI specifically includes reception level values of cells, and is related to a geographical location where the initial MI is reported by the terminal device. Typically, an initial MI of an a-cell comprises reception level values of the a-cell and reception level values of several neighbours of the a-cell.

In the embodiment of the present invention, the network system may acquire the initial MI of the at least two cells in various ways. For example, the at least two cells include a cell a and a cell B, and a base station of the cell a may receive B reported by the terminal device₁The base station of the initial MR, B cell can receive B reported by the terminal equipment₂An initial MR, the network system acquires the B through the base stations of the A cell and the B cell₁+b₂And (4) MR.

It should be understood that the Base Station may be a Base Transceiver Station (BTS) in Global System for mobile communications (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB) in Wideband Code Division Multiple Access (WCDMA), an eNB or evolved Node B (eNodeB) in LTE, a relay Station or Access point, or a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network.

In the embodiment of the present invention, as an example and not by way of limitation, the evaluation cell of each cell to be adjusted is used to evaluate whether the adjustment of the corresponding cell to be adjusted is qualified. For example, assuming that the a cell is a cell to be adjusted, although the coverage problem or the capacity problem of the a cell is solved after the a cell is adjusted, the adjustment of the a cell causes the coverage problem or the capacity problem of the evaluation cell of the a cell to occur, or the adjustment of the a cell causes the coverage problem or the capacity problem of the evaluation cell to deteriorate, the adjustment of the a cell is considered to be unqualified, the a cell needs to be adjusted again, and then the evaluation cell of the cell to be adjusted is described in detail.

S120, updating a first receiving level value of a cell to be adjusted included in each of the plurality of initial MIs according to at least one first value to be adjusted, to obtain a plurality of updated MIs, where the at least one first value to be adjusted and the at least one cell to be adjusted are in one-to-one correspondence, and the plurality of updated MIs and the plurality of initial MIs are in one-to-one correspondence;

specifically, after the network system obtains a plurality of initial MIs of the at least two cells, the network system updates the plurality of initial MIs according to the first value to be adjusted corresponding to each cell to be adjusted. Wherein, when updating the first reception level value included in the initial MI, only the first reception level value of the cell to be adjusted included in the initial MI is updated. Wherein the network system may update the plurality of initial MIs's to a plurality of updated MIs's in a variety of ways.

For example, the value to be adjusted is directly used to adjust a parameter to be adjusted (e.g., a transmission power value or a down tilt angle) of the cell. Fig. 2 is another schematic flow chart of a cell adjustment method according to an embodiment of the invention. In the embodiment of the present invention, as shown in fig. 2, the S120 may include, by way of example and not limitation:

s121, determining, according to a first value to be adjusted corresponding to a cell to be adjusted included in a first initial MI, a variation of a reception level value of the cell to be adjusted included in the first initial MI, where the first initial MI belongs to the plurality of initial MIs;

s122, determining a second receiving level value of the cell to be adjusted included in the first initial MI according to the variation of the receiving level value of the cell to be adjusted included in the first initial MI and the first receiving level value of the cell to be adjusted included in the first initial MI;

s123, obtaining a first updated MI according to a second receiving level value of the cell to be adjusted included in the first initial MI, where the first updated MI belongs to the plurality of updated MIs.

Specifically, assume that there are three cells to be adjusted, which are a cell, B cell, and C cell. The values to be adjusted corresponding to the three cells to be adjusted are [ x ] respectively₁，y₁，z₁]. The plurality of initial MIs includes a first initial MI, and the updating of the first initial MI to obtain a first updated MI may be as shown in table 1.

TABLE 1

As shown in Table 1, the first reception level value of the A cell in the first initial MI is-94 dBm, and after the update, the reception level value of the A cell included in the first updated MI is updated to-94 + x₂dBm. Similarly, the reception level value of the B cell is updated to-96 + y in the first update MI₂dBm (a relationship between the first adjustment value and the variation amount of the reception level value will be described later in detail). And the first initial MI comprisesThe first reception level values of the D cell, the E cell, and the F cell remain unchanged. It should be noted that, the variation of the reception level value of the cell to be adjusted included in the first initial MI is determined according to the first value to be adjusted corresponding to the cell to be adjusted included in the first initial MI, which is to be understood as that the variation of the reception level value of the cell to be adjusted in the corresponding initial MI is determined according to the variation of the parameter to be adjusted of the cell to be adjusted.

As another example, the value to be adjusted is directly used to adjust the reception level value of the cell. That is, without determining the amount of change, the first value to be adjusted is directly used to adjust the first reception level value of the cell to be adjusted included in the initial MI, thereby obtaining a plurality of updated MIs corresponding one-to-one to the plurality of initial MIs.

It should be understood that the operations related to updating each of the plurality of initial MIs may refer to the operations related to updating the first initial MI, and the description of the present invention is omitted herein for brevity. Therefore, a plurality of updated MIs corresponding to the plurality of initial MIs can be obtained according to the at least one value to be adjusted.

It should also be understood that, in the embodiment of the present invention, updating the plurality of initial MIs means acquiring a plurality of updated MIs according to the plurality of initial MIs, which are not actually covered or deleted.

It should be noted that, since the first initial MI listed above only includes two cells to be adjusted, the first reception level values of the two cells to be adjusted included in the first initial MI are updated by using corresponding values to be adjusted.

It should be further noted that the above-listed manners for obtaining the plurality of updated MI according to the at least one first value to be adjusted are only exemplary, and should not limit the present invention in any way. It is within the scope of the present invention to update the initial MI into a plurality of updated MIs corresponding to each other, and predict the adjusted cell condition according to the updated MIs.

S130, predicting the cell condition of the at least one cell to be adjusted after being adjusted by the at least one first value to be adjusted according to the plurality of updated MI;

specifically, the cell condition may include a variety. Optionally, the cell condition includes at least one of a loading amount of a first cell of the at least two cells, a coverage of the first cell, and a coverage of a cell group of the at least two cells, wherein the coverage includes at least one of a pilot pollution MI ratio, a coverage hole MI ratio, and a weak coverage MI ratio. (details will be given later on how to predict the cell condition corresponding to the at least one first value to be adjusted based on the plurality of updated MIs). The more factors the cell condition includes, the more preferable scheme can be adopted for adjusting the cell to be adjusted, thereby improving the user experience.

It should be noted that the first cell is any one of the at least two cells. The coverage situation and the capacity situation of one or more of the at least two cells may be predicted according to the method 100.

S140, if the cell condition of the at least one cell to be adjusted after being adjusted by the at least one first value to be adjusted reaches a preset standard, determining each first value to be adjusted as a target adjustment value of the corresponding cell to be adjusted.

Therefore, in the method 100 for adjusting a cell in the embodiment of the present invention, before actually adjusting the cell to be adjusted, the network system may first predict whether the cell condition of the cell to be adjusted after being adjusted correspondingly reaches a preset standard, and if the cell condition reaches the preset standard, determine the at least one first value to be adjusted as the target adjustment value, so that the network system or other devices may adjust the corresponding cell to be adjusted according to the target adjustment value, thereby avoiding repeated adjustment of the cell to be adjusted, and improving the adjustment efficiency. Moreover, the method 100 does not need high-precision longitude and latitude information, can realize the prediction of the adjustment scheme of the cell to be adjusted through the first receiving level values of the cells in the plurality of initial MIs of the at least two cells, and has the advantages of simple operation, easy realization and good compatibility with the prior art.

It should be understood that "first" and "second" in the implementation of the present invention are used to distinguish different level values or values to be adjusted, and should not constitute any limitation to the present invention.

It should be noted that, if the at least one first value to be adjusted is directly used to adjust the parameter to be adjusted of the cell to be adjusted, the updated MI needs to be obtained by first determining the variation of the reception level value of the cell to be adjusted included in the first initial MI according to each first value to be adjusted; if the at least one first value to be adjusted is directly used for adjusting the receiving level value of the cell to be adjusted included in the first initial MI, after the first value to be adjusted is determined to be the target adjustment value, the variation of the parameter to be adjusted included in each initial MI of the cell to be adjusted needs to be determined according to each first value to be adjusted, and then the parameter to be adjusted of the cell to be adjusted is adjusted according to the variation of the parameter to be adjusted included in each initial MI of the cell to be adjusted. The method 100 does not need a high-precision data source, realizes the prediction of the adjustment scheme through easily-obtained parameters, and has simple operation and good compatibility.

Fig. 3 is a further schematic flow chart of a cell adjustment method according to an embodiment of the present invention. Optionally, in the embodiment of the present invention, as shown in fig. 3, by way of example and not limitation, before the network system acquires the plurality of initial measurement information MI of at least two cells, the method 100 may further include:

s101, determining a problem cell;

s102, determining at least one cell to be adjusted of the problem cell;

s103, determining an evaluation cell corresponding to each cell to be adjusted in at least one cell to be adjusted.

Specifically, the problem cell may refer to a cell in which a coverage problem or a capacity problem exists. There are various ways for the network system to determine the problem cell.

For example, the network system may obtain multiple MIs for a serving cell from which the serving cell is determined to be a problem cell.

For another example, the network system may obtain session data of the serving cell, and determine that the serving cell is the problem cell according to the session data of the serving cell.

For another example, the network system may receive indication information transmitted by the other device, where the indication information is used to indicate the problem cell, and the network system determines the problem cell according to the indication information.

After the network system determines the problem cell, a cell to be adjusted of the problem cell can be constructed. The parameters to be adjusted for cell adjustment are different, and the cells to be adjusted constructed are also different, which will be described in detail later. The network system may determine the evaluation cell corresponding to each cell to be adjusted in various ways.

Optionally, in the embodiment of the present invention, by way of example and not limitation, the network system may determine an evaluation cell of each cell to be adjusted according to the location information of each cell to be adjusted;

specifically, the network system may use a neighboring cell with the same frequency adjacent to the geographic location of the cell to be adjusted as an evaluation cell of the cell to be adjusted. For example, the network system may sort a plurality of co-frequency neighboring cells adjacent to the cell to be adjusted from near to far according to the distance between the co-frequency neighboring cells and the cell to be adjusted, and select one or more co-frequency neighboring cells closest to the cell to be adjusted as the evaluation cell of the cell to be adjusted.

Optionally, in the embodiment of the present invention, as an example and not by way of limitation, the network system may further determine the evaluation cell of each cell to be adjusted according to the number of times of switching between each cell to be adjusted and the corresponding co-frequency neighboring cell.

Specifically, the network system may use a neighboring cell with the same frequency that is switched with the cell to be adjusted closely as an evaluation cell of the cell to be adjusted. For example, the network system may count the number of times of switching between the cell to be adjusted and the co-frequency neighboring cells according to the number of times of successful switching or switching requests of every two cells in the traffic statistics data of the cell to be adjusted, sort the plurality of co-frequency neighboring cells of the cell to be adjusted according to the number of times of switching between the co-frequency neighboring cells and the cell to be adjusted from large to small, and select one or several co-frequency neighboring cells that are most closely switched with the cell to be adjusted as the evaluation cell of the cell to be adjusted.

It should be understood that the above listed methods for determining problem cells and evaluating cells are only exemplary and should not limit the present invention in any way, and the number of evaluating cells corresponding to each cell to be adjusted can be selected according to actual needs, and the present invention is not limited herein.

It should also be understood that the network system may obtain the location information of each cell to be adjusted through the engineering parameters and/or configuration information of the cell to be adjusted; the network system can acquire the switching times of each cell to be adjusted and the adjacent cell through the speech system data of each cell to be adjusted. Further, the network system may also obtain the location information or the handover information of each cell to be adjusted through other manners, which is not limited herein.

In the above, the method 100 for adjusting a cell according to the embodiment of the present invention is described in detail in a general point of view. Hereinafter, the method 100 will be described in detail from the perspective of power adjustment and antenna feed adjustment (downtilt adjustment), respectively.

First, power regulation

Optionally, in the embodiment of the present invention, by way of example and not limitation, the at least one cell to be adjusted may include at least the following two cases:

case one (cell to be adjusted includes key cell to be adjusted)

Typically, some cells are adjusted to address coverage or capacity issues of the problem cell. The cell to be adjusted for solving the coverage problem or the capacity problem may be referred to as a critical cell to be adjusted.

For example, the problem cell is a cell with weak coverage, and the problem of weak coverage of the problem cell can be solved by adjusting the transmission power value of the problem cell, and at this time, the problem cell can be used as a key cell to be adjusted. For another example, the problem cell is a pilot pollution cell, and in general, the pilot pollution problem is for a group of cells with overlapping coverage. The serving cell may be determined to be a pilot polluted cell based on a proportion of pilot polluted MIs among the plurality of MIs of the serving cell. When determining the pilot pollution MI, recording the pollution source cell corresponding to the pilot pollution cell for each pilot pollution MI, and determining at least one cell to be adjusted corresponding to the pilot pollution cell and an adjustment direction of the at least one cell to be adjusted according to indexes such as various coverage problem ratios, loads and the like of the pollution source cells of which the pilot pollution contribution ratio is higher than a certain threshold. The judging mode of the pilot pollution MI comprises the following formula:

ServerCell _ RSCP is more than or equal to RSCP threshold (1)

N_{|ServerCell_RSCP-NeighborCell_RSCP|<Overlapping coverage threshold}>Strong pilot frequency number threshold (2)

Wherein, ServerCell _ RSCP is the Received Signal Power (referred to as "RSCP") of the main serving cell (ServerCell) Received by the terminal equipment, and N is_{|ServerCell_RSCP-NeighborCell_RSCP|<Overlapping coverage threshold}The number of strong pilots. If the absolute value of the difference between the pilot frequency of the main service cell received by the terminal equipment and the pilot frequency of the neighboring cell (neighbor cell) received by the terminal equipment (such as cell A) is larger than the overlapping coverage threshold, the pilot frequency of the cell A received by the terminal equipment is a strong pilot frequency. And when the number of the strong pilot frequency in one MI is larger than the threshold of the number of the strong pilot frequency, determining the MI as the pilot frequency polluted MI. In other words, a certain MI is determined to be a pilot polluted MI when the MI satisfies equations (1) and (2).

It should be understood that in the UMTS system, the PSCP may be used to measure the coverage of the corresponding cell, and in the LTE system, the Reference Signal Receiving Power (RSRP) may be used to measure the coverage of the corresponding cell.

Therefore, the problem of pilot pollution can be solved by increasing the difference value of the receiving level values of the main pilot cell and the adjacent cell received by the terminal equipment. The at least one cell to be adjusted constructed according to the pilot frequency polluted cell may include at least one of the pilot frequency polluted cell and a pollution source cell of the pilot frequency polluted cell, wherein both the pilot frequency polluted cell and the pollution source cell may be used as a cell to be adjusted, and the problem of pilot frequency pollution of the pilot frequency polluted cell is solved by adjusting the transmission power of the cell to be adjusted.

Case two (the at least one cell to be adjusted includes not only the key cell to be adjusted but also the co-coverage cell of each key cell to be adjusted)

When the cells to be adjusted are adjusted, each cell to be adjusted and its corresponding adjacent cell with the same coverage frequency band and different frequency points may become a blind-cut adjacent cell, and in order to ensure that the blind-cut is successful, the pilot powers of the cell to be adjusted and the cell to be covered are required to be consistent (the coverage is consistent). Therefore, when adjusting the cell to be adjusted, it is necessary to perform synchronous adjustment on the cell to be adjusted and the coverage cell of the cell to be adjusted. The synchronization adjustment refers to adjusting the key cell to be adjusted and the cell with the same coverage of the key cell to be adjusted by using the same value to be adjusted, for example, a cell a is the key cell to be adjusted, and the cell with the same coverage of the cell a is a cell B and a cell C. The transmission power value of the cell a is increased by xdBM, and the transmission power values of the cell B and the cell C need to be increased by xdBM respectively.

Optionally, the network system may identify the cells with the same coverage of each key cell to be adjusted according to the engineering parameters and/or the configuration information of each key cell to be adjusted.

It should be noted that the above listed critical cells to be adjusted are only exemplary, and should not limit the present invention. In any cell adjustment method, the same coverage cell or common antenna feeder cell of a type of cell to be adjusted is also used as the cell to be adjusted to perform synchronous adjustment, and the method falls into the protection scope of the invention.

The network system may determine, according to a first value to be adjusted corresponding to the cell to be adjusted included in the first initial MI, a variation of the reception level value of the cell to be adjusted included in the first initial MI, thereby obtaining the first updated MI. Optionally, the network system may determine, through a correspondence between a variation of the cell transmission power value and a variation of the cell reception level value and a first value to be adjusted corresponding to the cell to be adjusted included in the first initial MI, the variation of the reception level value of the cell to be adjusted included in the first initial MI, so as to obtain the first updated MI.

Specifically, the power adjustment has a linearly changing characteristic. In general, it can be assumed that, when the transmission power value of the transmitting end changes, the receiving end has the same amount of change in the reception level value of the received signal at different receiving locations. Further, it can also be assumed that the amount of change in the transmission power value at the transmitting end and the amount of change in the reception level value at the receiving end are the same. For example, the value of the transmission power of the A cell is P₀The terminal equipment receives the receiving level value of the A cell at D1 as P₁The terminal equipment receives the receiving level value of the A cell at D2 as P₂. The value to be adjusted of the transmission power value of the cell a comprises Δ P, and the transmission power value of the cell a is adjusted by the Δ P (namely the transmission power value of the cell a is changed into P after adjustment)₀+ Δ P), it can be considered that the receiving level values of the a cells received by the terminal device at D1 and D2 are changed by Δ P (i.e., after adjustment, the receiving level values of the a cells received by the terminal device at D1 and D2 become P, respectively₁+ Δ P and P₂+Δp)。

Still taking Table 1 as an example, if power adjustment is performed for the cell to be adjusted, the [ x ] is₁，y₁，z₁]＝[1，3，1]Determining [ x ] according to the variation of the cell transmission power value and the variation of the cell reception level value₂，y₂，z₂]＝[1，3，1]. The first initial MIThe updated first updated MI can be as shown in table 2.

TABLE 2

Therefore, if the at least one cell to be adjusted is power-adjusted, each of the values to be adjusted may be mapped to the variation of the reception level value of each cell to be adjusted according to the correspondence between the variation of the transmission power value of the cell and the variation of the reception level value of the cell, so as to update the plurality of initial MIs to the plurality of updated MIs.

Second, antenna feeder adjustment (lower inclination angle adjustment)

Optionally, in the embodiment of the present invention, as an example and not by way of limitation, similar to power adjustment, the at least one cell to be adjusted may also include at least the following two cases:

case one (cell to be adjusted includes key cell to be adjusted)

The relevant description of the cell to be adjusted may refer to the relevant description of the cell to be adjusted in the power adjustment, which is not described herein again.

Case two (the at least one cell to be adjusted includes not only the key cell to be adjusted but also the co-antenna feeder cell of the key cell to be adjusted)

When the cell to be adjusted is adjusted, because the cell to be adjusted and the corresponding common antenna feeder cell share one antenna, the downtilt adjustment of the cell to be adjusted may result in consistent adjustment of the common antenna feeder cell of the cell to be adjusted.

Optionally, the network system may identify the common antenna feeder cell of the key cell to be adjusted according to the engineering parameter and/or the configuration information of the key cell to be adjusted.

The network system may determine, according to a first value to be adjusted corresponding to the cell to be adjusted included in the first initial MI, a variation of the reception level value of the cell to be adjusted included in the first initial MI, thereby obtaining the first updated MI. Alternatively, the network system may determine the amount of change in the reception level value of the cell to be adjusted included in the first initial MI in at least the following two ways.

In a first way,

In the embodiment of the present invention, as an example and not by way of limitation, each initial MI includes a Timing Advance (TA), and the variation of the reception level value of the cell to be adjusted included in the first initial MI is determined according to the variation of the cell downtilt, a mapping table of the TA and the variation of the antenna attenuation, and a first value to be adjusted corresponding to the cell to be adjusted included in the first initial MI.

Specifically, in a normal case, it can be assumed that the ambient environment is not changed, and the amount of change in the antenna attenuation is the amount of change in the received signal strength of the terminal device (i.e., the amount of change in the cell reception level value). The mapping table of the variation of the cell downtilt angle, the TA, and the variation of the antenna attenuation may be shown in table 3.

TABLE 3

Taking table 4 as an example, if the adjustment of the downtilt angle is performed on the cell to be adjusted, the first initial MI includes TA of 2, where a cell is the cell to be adjusted, and the downtilt angle change amount x of the a cell is the cell to be adjusted₁1, according to the mapping table, the antenna attenuation variation is determined to be 2, so that the receiving level value of the cell is worth the variation x₂2. The first initial MI is updated to obtain a first updated MI as shown in Table 4Shown in the figure.

TABLE 4

Therefore, if the downtilt adjustment is performed on the at least one cell to be adjusted, each value to be adjusted may be mapped to the variation of the reception level value of each cell to be adjusted according to a mapping table of the variation of the downtilt angle of the cell, the TA, and the variation of the antenna attenuation, so as to update the plurality of initial MIs into a plurality of updated MIs.

The second way,

In the embodiment of the present invention, each initial MI includes a TA, and the amount of change in the reception level value of the cell to be adjusted included in the first initial MI is determined according to the first value to be adjusted corresponding to the cell to be adjusted included in the first initial MI and the TA included in the first initial MI, by way of example and not limitation.

The difference between the first and second modes is that the second mode does not require the mapping table. The network system may determine, according to the variation of the cell downtilt angle and the correspondence between the TA and the variation of the antenna attenuation, the variation of the reception level value of the cell to be adjusted included in the first initial MI. Alternatively, each of the initial MIs's may include the same TA, and the network system may determine the variation of the reception level value of the cell to be adjusted included in each of the initial MIs's according to a corresponding relationship between the variation of the cell downtilt angle and the variation of the antenna attenuation.

It should be noted that the mapping tables of the variation of the cell downtilt angle, the TA, and the variation of the antenna attenuation listed above are only exemplary, and should not be construed as limiting the invention.

It should be further noted that the network system may calculate the amount of change of the antenna attenuation after the downtilt angle at different TAs changes by a certain degree according to the TA reported by the terminal device, the engineering parameters, and the antenna file, and further obtain a mapping table of the amount of change of the downtilt angle from-TA to the amount of change of the antenna attenuation. The network system may also obtain the mapping table in other manners. The mapping table may be used for pre-evaluation of subsequent cell adjustments.

From the perspective of power adjustment and the perspective of antenna feed adjustment, it was explained in detail how to determine the variation of the reception level value of the cell to be adjusted included in the first initial MI according to the first value to be adjusted corresponding to the cell to be adjusted included in the first initial MI. In the following, how to predict the cell condition of the at least one cell to be adjusted after the adjustment of the at least one first value to be adjusted according to the updated MIs is described in detail.

For example, in the embodiment of the present invention, the determining the cell condition of the at least one cell to be adjusted after being adjusted by the at least one first value to be adjusted according to the plurality of updated MIs may include, by way of example and not limitation: according to the number (or the amount of change) of the active state MI of the first cell of the at least two cells included in the plurality of updated MIs, the load amount (or the amount of change) of the first cell after the at least one cell to be adjusted is adjusted by the at least one first value to be adjusted is determined.

Specifically, in an MI, if the reception level of a cell received by the terminal device satisfies the following three conditions, the cell may be considered as an active set cell of the MI:

condition 1, the receiving level of the cell received by the terminal equipment is greater than or equal to the minimum receiving level requirement of the terminal equipment;

condition 2, the strongest receiving level of the terminal equipment-the receiving level of the terminal equipment for receiving the cell is less than or equal to a level difference threshold;

condition 3 the number of active set cells is less than or equal to the maximum number of active sets (typically the maximum number of active sets is 3).

An MI may be considered an active state MI for a cell if the cell is included in its active set cell. In general, three cells with strongest signals received by the terminal equipment in a MI can be used as active set cells of the MI. Further, the network system may count the number of active MI of the first cell in the plurality of updated MI so as to predict the load amount of the first cell. For example, assuming that the a cell is a cell to be adjusted, the number of active MI of the a cell is 70 in 100 initial MI, and the active MI of the a cell becomes 60 after the 100 initial MI is adjusted to 100 updated MI by using at least one first value to be adjusted. The active state MI of the cell a to be tuned is reduced by 1/7, and accordingly the load of the cell a to be tuned is considered to be reduced by 1/7. Alternatively, the variation of the active state number may not be counted, and if the active state MI of the cell a is determined to be 60 corresponding load amounts.

For another example, but not by way of limitation, in the embodiment of the present invention, the determining, according to the updated MIs, the cell condition of the at least one cell to be adjusted after being adjusted by the at least one first value to be adjusted includes: and determining the load capacity (or the variable quantity of the load capacity) of the first cell to be adjusted after the at least one cell to be adjusted is adjusted by the at least one first value to be adjusted according to the number (or the variable quantity of the number) of the downlink Physical Resource Blocks (PRBs) occupied by the terminal equipment in the plurality of updated MIs.

Specifically, the network system may count the number of the first cell updated MI having the strongest reception level value among the plurality of updated MI as the first cell updated MI, and further count the number of the downlink physical Resource blocks prb (physical Resource blocks) occupied by the terminal device in each first cell updated MI. The network system predicts the load amount (or the variation of the load amount) of the first cell according to the number (or the variation of the number) of PRBs occupied by the terminal device in the plurality of updated MIs in the first cell.

It should be noted that, in the UMTS system, the network system may predict the load amount of the first cell according to the number of active states MI of the first cell; in the LTE system, the network system may predict a load amount of the first cell according to the number of PRBs of the first cell occupied. In the embodiment of the invention, the load capacity and the coverage condition of one or more cells in at least two cells can be predicted.

It should be noted that, in the embodiment of the present invention, the first cell may be any one of at least two cells, and for predicting the load capacity of any one of the at least two cells, reference may be made to prediction of the load capacity of the first cell, which is not described herein again for brevity.

Alternatively, the preset criterion may include at least one of a cell group pollution preset criterion, a cell group coverage hole preset criterion, a cell group weak coverage preset criterion, and a cell load preset criterion.

For example, the preset criteria may include a preset criteria for cell group contamination, and meeting the preset criteria for cell group contamination includes satisfying the following formula:

wherein,for a number of updated MI cell group pilot contamination MI ratios derived from the at least one first value to be adjusted,a cell group pilot contamination MI proportion of the plurality of initial MI;a tolerance threshold for contamination degradation. The MI ratio of cell group pilot pollution is as follows: (number of all pilot contaminating MIs within a cell group)/(number of all MIs within a cell group). The method for determining the MI due to pilot pollution may refer to the above description, and for brevity, the present invention is not described again. Therefore, if adjusted, the ratio of MI to the cell group pilot pollution MI corresponding to the plurality of initial MIAnd then, the proportion of the cell group pilot pollution MI in the plurality of updated MI is not increased or the increment of the cell group pilot pollution MI does not exceed the pollution deterioration tolerance threshold, and the cell condition is considered to reach the preset standard of the cell group pollution.

For another example, the preset criterion may further include a cell group weak coverage preset criterion, and meeting the cell group weak coverage preset criterion includes satisfying the following formula:

wherein,for a cell group weak coverage MI fraction of a plurality of updated MI's derived from the at least one first value to be adjusted,for the cell group weak coverage MI fraction in the plurality of initial MIs,a weak coverage degradation tolerance threshold.

Specifically, the cell group weak coverage MI ratio refers to: (number of all weakly covered MIs within cell group)/(number of all MIs within cell group). Wherein the weak coverage MI comprises: and if the receiving level value of the main service cell is lower than the weak coverage threshold, determining the MI as the weak coverage MI. Therefore, if the cell group weak coverage MI ratios of the plurality of updated MIs are not increased or the increment does not exceed the weak coverage deterioration tolerance threshold after adjustment, relative to the cell group weak coverage MI ratios corresponding to the plurality of initial MIs, the cell condition cell group weak coverage preset standard is considered.

For another example, the preset criterion may further include a coverage hole preset criterion, and the reaching of the coverage hole preset criterion includes satisfying the following formula:

wherein,in order to obtain a plurality of cell group coverage hole MI proportions corresponding to the updated MI according to at least one first value to be adjusted,for the cell group coverage hole MI proportion corresponding to the plurality of initial MIs,a tolerance threshold for coverage hole degradation.

Specifically, the cell group coverage hole MI ratio refers to: (number of all coverage holes MI in the cell group)/(number of all MI in the cell group). Wherein the coverage hole MI comprises: and if the receiving level value of the main service cell is lower than the receiving level value threshold of the coverage hole, determining the MI as the coverage hole MI. Therefore, with respect to the cell group coverage hole MI ratios corresponding to the initial MI ratios, if the cell group coverage hole MI ratios are not increased or the increment does not exceed the coverage hole deterioration tolerance threshold after adjustment, the cell condition is considered to reach the preset cell group coverage hole standard.

For another example, the preset criteria further include a cell load preset criterion, and the meeting of the cell load preset criterion includes: in the plurality of updated MIs, after the cell to be adjusted for increasing the transmission power value is adjusted, the increase of the load capacity of the cell to be adjusted for increasing the transmission power value does not exceed the load tolerance threshold, and after the cell to be adjusted for decreasing the transmission power value is adjusted, the increase of the load capacity of the evaluation cell corresponding to the cell to be adjusted for decreasing the transmission power value does not exceed the load tolerance threshold, and the cell condition is considered to reach the load preset standard.

Further, it is described in detail above how to obtain a plurality of updated MI according to the at least one first value to be adjusted, and determine the at least one first value to be adjusted as the corresponding target adjustment value of the at least one cell to be adjusted according to the updated MI. In general, the network system may include, before determining each first value to be adjusted as the target adjustment value of the corresponding cell to be adjusted:

updating a first receiving level value of a cell to be adjusted included in each of the plurality of initial MIs according to at least one second value to be adjusted to obtain a plurality of second updated MIs, wherein the at least one second value to be adjusted is in one-to-one correspondence with the at least one cell to be adjusted, and the plurality of second updated MIs are in one-to-one correspondence with the plurality of initial MIs;

predicting the cell condition of each cell to be adjusted after being adjusted by the corresponding first value to be adjusted according to the plurality of second updated MI;

and determining that the comprehensive score of the cell condition of the at least one cell to be adjusted after being adjusted by the at least one first value to be adjusted is higher than the comprehensive score of the cell condition of the at least one cell to be adjusted after being adjusted by the at least one second cell to be adjusted.

In particular, the at least one value to be adjusted may constitute one set of values to be adjusted. For example, the at least one first value to be adjusted may constitute a first set of values to be adjusted; the at least one second value to be adjusted may constitute a second set of values to be adjusted. In general, before determining a target adjustment value of each cell to be adjusted, a cell condition corresponding to each set of values to be adjusted in a plurality of sets of values to be adjusted is predicted. Wherein, a set of values to be adjusted corresponds to a set of updated MI. A set of updated MIs corresponds to a cell condition. The network system can predict a plurality of sets of values to be adjusted, and determines the most preferable set of values to be adjusted from the plurality of sets of values to be adjusted as a target set of adjustment values. Optionally, the network system may obtain the plurality of sets of values to be adjusted. For example, a plurality of sets of values to be adjusted may be determined according to the current transmission power value of the cell to be adjusted, or a plurality of values to be adjusted may be determined according to the reception level value of the cell to be adjusted received by the terminal deviceAnd the set of a plurality of values to be adjusted can be determined according to other methods. Further, suppose there are two cells to be adjusted, which are a cell a and a cell B, respectively, and the cell a and the cell B need to be adjusted, respectively. Wherein the value to be adjusted of the cell A is [ x₁，x₂]The value to be adjusted of cell B is [ y₁，y₂]. The set of values to be adjusted for the a cell and the B cell may include [ x [ ]₁，y₁]、[x₁，y₂]、[x₂，y₁]And [ x ]₂，y₂]. At this time, the two cells to be adjusted may correspond to four sets of values to be adjusted. The number of the value sets to be adjusted may be determined according to the number of the value sets to be adjusted corresponding to each cell to be adjusted, or may be determined according to other manners, which is not limited herein.

If the cell conditions corresponding to a plurality of value sets to be adjusted all meet the preset standard, a comprehensive score corresponding to each value set to be adjusted can be calculated in a weighted manner, and the value to be adjusted in the value set to be adjusted with the highest comprehensive score is selected as the target adjustment value (in the embodiment of the invention, the group of value sets to be adjusted with the highest comprehensive score is the first value set to be adjusted).

For example, the network side device obtains a first set of updated MI according to at least one first value to be adjusted (i.e. a first set of values to be adjusted), and the network side device obtains a second set of updated MI according to at least one second value to be adjusted (i.e. a second set of values to be adjusted). Wherein the first set of updated MIs corresponds to the plurality of updated MIs, and the second set of updated MIs corresponds to the plurality of second updated MIs. Determining a score for each scoring factor in the first updated MI, determining a score for each scoring factor in the second updated MI, the scoring factors including at least two of a cell group pilot contamination factor, a cell group weak coverage factor, a cell group coverage hole factor, and a cell load factor, determining a weight for each scoring factor, and weighting the composite score for the first updated MI and the composite score for the second updated MI; the first set of updated MI is assigned a composite score that is higher than the composite score of the second set of updated MI. The weight of each scoring factor can be randomly determined, or determined according to some actual conditions, the requirements of a cell or the requirements of a user. For example, the weight of the cell load factor may be set to 70% according to some cases, and the sum of the weights of the other scoring factors is 30%. And selecting a value to be adjusted in a group of values to be adjusted corresponding to the updated MI with the highest comprehensive score as a target adjustment value of the at least one cell to be adjusted.

Alternatively, a score table may be developed from which the score for each scoring factor in each set of updated MIs's is determined.

The above-listed methods for determining the target adjustment value are only exemplary, and should not limit the present invention. The network system may also determine the target adjustment value of the cell to be adjusted by other methods.

It should be noted that the preset criteria listed above are only exemplary and should not limit the present invention, and the preset criteria may also include other criteria for measuring the cell coverage condition or the load condition.

The adjustment scheme of the adjustment cell is predicted by combining a plurality of updated MI, and then the target adjustment value corresponding to each cell to be adjusted can be determined. A method of cell adjustment according to another embodiment of the present invention is described below. Fig. 4 is a schematic flow chart 200 of a method of cell adjustment according to another embodiment of the present invention, as shown in fig. 4, the method 200 includes:

s210, acquiring a first receiving level value of a cell to be adjusted;

s220, determining the variation of the receiving level value of the cell to be adjusted according to the value to be adjusted of the cell to be adjusted;

s230, determining a second receiving level value of the cell to be adjusted according to the first receiving level value and the variation of the receiving level value, wherein the second receiving level value is used for predicting whether the cell condition of the cell to be adjusted after being adjusted by the receiving level value reaches a preset standard;

s240, if the cell condition of the cell to be adjusted after the adjustment of the value to be adjusted reaches a preset standard, determining the value to be adjusted as a target adjustment value of the cell to be adjusted.

The method 200 may be used to implement the method 100. The method 200 can predict the second receiving level value of the cell to be adjusted after being adjusted by the value to be adjusted through the variation of the receiving level value of the cell to be adjusted.

Optionally, the value to be adjusted is used to adjust the transmission power value of the cell to be adjusted, and the variation of the reception level value of the cell to be adjusted is determined according to the value to be adjusted of the cell to be adjusted; the method comprises the following steps: and determining the variation of the receiving level value of the cell to be adjusted according to the corresponding relation between the variation of the transmitting power value of the cell and the variation of the receiving level value of the cell and the value to be adjusted.
