Description

Cell evaluation method, device and computer readable storage medium

Technical Field

The present application relates to the field of communications, and in particular, to a cell evaluation method, apparatus, and computer readable storage medium.

Background

Non-independent (NSA) networking is a networking approach with a dual connectivity architecture. The dual connectivity architecture means that the terminal device can use radio resources of at least two different base stations including the primary station and the secondary station simultaneously in a connected state. The primary station is an anchor point of the terminal equipment accessing the network, also called an anchor point station or an anchor point cell, and is used for providing a signaling control function of the terminal equipment accessing the network and can provide a user plane data forwarding function, and the secondary station only provides additional user plane data forwarding resources for the terminal equipment and can also be called a secondary cell.

To evaluate coverage quality of anchor cells, in the prior art, evaluation is typically based on drive test and spot test, network management monitoring and deep packet inspection techniques (deeo packet inspection, DPI), etc. However, drive test and fixed point test have limited coverage, have high input cost, and are generally only applied in the initial stage of network establishment; network management monitoring focuses on the operation quality of network equipment, and lacks comprehensive monitoring on the aspect of users and evaluation on service perception; DPI evaluates traffic awareness through core network data, lacking wireless side quality evaluation. In addition, the above schemes are all based on the data of the anchor station, and the dual connection condition of the anchor station and the necessity of configuring the anchor station cannot be judged from the data. Meanwhile, the scheme is not associated with a New Radio (NR) secondary station cell which is connected with the primary station cell in a double way, so that when a user perception problem occurs under NSA networking, the problem cannot be delimited, namely whether the problem of the NR secondary station cell is self coverage or the problem of the coverage of an anchor point cell connected with the NR secondary station cell is not judged, and the positioning of the cell with the specific problem cannot be realized.

Disclosure of Invention

Furthermore, the various steps may be performed in a different order presented in accordance with embodiments of the present application, and it is possible that not all of the operations in the embodiments of the present application may be performed.

As shown in fig. 2, a cell evaluation method provided in an embodiment of the present application includes the following steps:

s201, the cell evaluation device acquires measurement report data, wherein the measurement report data comprises measurement report data of one or more anchor cells within a set duration and measurement report data of one or more auxiliary cells with a dual-connection architecture with the one or more anchor cells.

As a possible implementation, the anchor cell may be an LTE cell and the secondary cell may be an NR cell.

As a possible implementation, the measurement report data may be measurement report data periodically reported with a certain period of time, and the measurement report may be measurement report data periodically reported with a period of 10 seconds, or the measurement report may be measurement report data periodically reported with a period of 20 seconds, for example. Of course, the measurement report data may be periodically reported in other periods, which is not limited in this application.

As one possible implementation, the measurement report data of the anchor cell includes one or more of a cell identity of the anchor cell, a reference signal received power (reference signal received power, RSRP) of the anchor cell, or a reference signal received quality (reference signal reception quality, RSRQ) of the anchor cell. Illustratively, taking an anchor cell as an LTE cell as an example, the cell identification code of the anchor cell may be denoted as an LTE cell global identifier (Cell Global Identifier, cgi), the RSRP of the anchor cell may be denoted as an LTE RSRP, and the RSRQ of the anchor cell may be denoted as an LTE RSRQ.

As one possible implementation, the measurement report data of the secondary cell having a dual connectivity architecture with the anchor cell includes one or more of a cell identity of the secondary cell, RSRP of the secondary cell, RSRQ of the secondary cell, or reference signal to noise ratio (signal to noise ratio, SINR) of the secondary cell. For example, taking the secondary cell as an NR cell as an example, the cell identification code of the secondary cell may be denoted as NRCgi, the RSRP of the secondary cell may be denoted as NRRSRP, the RSRQ of the secondary cell may be denoted as NRRSRQ, and the SINR of the secondary cell may be denoted as NRSINR.

S202, the cell evaluation device determines whether the first anchor cell is a necessary anchor cell according to measurement report data of the first anchor cell in the one or more anchor cells and measurement report data of one or more auxiliary cells with dual-connection architecture with the first anchor cell.

The first anchor point cell is any anchor point cell in one or more anchor point cells.

In this step, the cell evaluation apparatus can determine whether the first anchor cell is a necessary anchor cell by using measurement report data of the first anchor cell of the one or more anchor cells and measurement report data of one or more secondary cells having a dual connectivity architecture with the first anchor cell, and when the first anchor cell is a necessary anchor, execute step S203 described below.

As a possible implementation, after step 202, if the first anchor cell is an unnecessary anchor cell, the anchor configuration of the anchor cell may be subsequently canceled. Of course, other operations may be performed on the first anchor cell, which is not limited in this application.

S203, if the first anchor cell is a necessary anchor cell, the cell evaluation device determines the network coverage state of the first auxiliary cell according to measurement report data of the first auxiliary cell in one or more auxiliary cells with double connection architecture with the first anchor cell; and the cell evaluation device determines the network coverage state of one or more anchor cells which are in double connection with the first auxiliary cell according to the measurement report data of one or more anchor cells which are in double connection with the first auxiliary cell.

The first auxiliary cell is any one auxiliary cell in one or more auxiliary cells with double-connection architecture with the first anchor cell.

As a possible implementation, if the cell evaluation device determines that the network coverage state of the first secondary cell is not good, the first secondary cell may be determined to be a problem cell; or if the cell evaluation device determines that the network coverage state of a certain anchor cell which is in dual connection with the first auxiliary cell is not good, the anchor cell can be determined to be a problem cell.

In one aspect, in the embodiment of the present application, the measurement report data acquired by the cell evaluation device includes measurement report data of one or more anchor cells within a set duration and measurement report data of one or more secondary cells having a dual-connection architecture with the one or more anchor cells, and the cell evaluation device may determine whether the first anchor cell is a necessary anchor cell according to the measurement report data of the first anchor cell of the one or more anchor cells and the measurement report data of the one or more secondary cells having a dual-connection architecture with the first anchor cell, so that based on the scheme, the dual-connection condition of the anchor station and the necessity of configuring the anchor station may be determined. On the other hand, in the embodiment of the present application, in the case where the first anchor cell is the necessary anchor cell, the cell evaluation device may determine, according to measurement report data of the first secondary cell of the one or more secondary cells having a dual-connection architecture with the first anchor cell and measurement report data of the one or more anchor cells that perform dual-connection with the first secondary cell, a network coverage state of the first secondary cell and a network coverage state of the one or more anchor cells that perform dual-connection with the first secondary cell, respectively. If the cell evaluation device determines that the network coverage state of the first auxiliary cell is not good, the first auxiliary cell can be determined to be a problem cell, and if the cell evaluation device determines that the network coverage state of a certain anchor cell which is in double connection with the first auxiliary cell is not good, the anchor cell can be determined to be a problem cell. That is, based on this scheme, positioning of a specific problem cell can be achieved. In summary, based on the cell evaluation method provided by the embodiment of the application, not only the dual connection condition of the anchor point station and the necessity of configuring the anchor point station can be judged, but also the positioning of the cell with specific problem can be realized.

The foregoing is a general description of the cell evaluation method provided by the present application, and the cell evaluation method provided by the present application will be further described below.

For the above step S202, as a possible implementation, the cell evaluation device determines, according to measurement report data of a first anchor cell of the one or more anchor cells and measurement report data of one or more secondary cells having a dual connectivity architecture with the first anchor cell, whether the first anchor cell is a necessary anchor cell, including: the cell evaluation device determines the proportion of the first anchor cell to double connection according to the measurement report data of the first anchor cell in the one or more anchor cells and the measurement report data of one or more auxiliary cells with double connection architecture with the first anchor cell; if the proportion of the first anchor point cell for double connection is larger than a first threshold value, determining the first anchor point cell as a necessary anchor point cell; otherwise, the first anchor point cell is determined to be an unnecessary anchor point cell.

The cell evaluation apparatus determines a ratio of a number of measurement reports of one or more secondary cells having a dual connectivity architecture with the first anchor cell to a number of measurement reports of the first anchor cell as a ratio of the first anchor cell to make dual connectivity.

For example, taking an anchor cell as an LTE cell, a secondary cell as an NR cell, a set duration of 50 seconds, and a period of a certain duration of 10 seconds as an example, table 1 is an example of measurement report data of a first anchor cell and measurement report data of one or more secondary cells having a dual-connection architecture with the first anchor cell provided in the present application:

TABLE 1

Wherein, reportTime indicates the time when the measurement report data is reported, XX indicates that the cell data is not null, and can be any value, and a blank cell indicates that the cell has no data or the data is null.

In combination with table 1, the total of 6 measurement report data of LteCell1 within 50 seconds, i.e., the number of measurement reports of LteCell1 is 6. The presence of measurement report data for the secondary cell by LteCell1 at 00:00:00, 00:00:20, 00:00:30, and 00:00:50 indicates that LteCell1 is now dual-connected with the secondary cell, i.e., the number of measurement reports for one or more secondary cells with dual-connection architecture with LteCell1 is 4. Thus, the ratio of the dual connection performed by LteCell1 = the number of measurement reports per one or more secondary cells with dual connection architecture with LteCell 1/the number of measurement reports of LteCell1 = 4/6 = 2/3.

After determining the proportion of the LteCell1 to be connected in double, comparing the proportion of the LteCell1 to be connected in double with a first threshold value by the cell evaluation device, and determining the LteCell1 as a necessary anchor cell if the proportion of the LteCell1 to be connected in double is greater than the first threshold value; otherwise, the LteCell1 is determined to be an unnecessary anchor cell. Taking the first threshold value of 0.5 as an example, 2/3≡0.67 > 0.5, the cell evaluation device may determine that LteCell1 is the necessary anchor cell.

For the above step S203, as a possible implementation, the cell evaluation device determines, according to measurement report data of a first secondary cell of one or more secondary cells having a dual connectivity architecture with the first anchor cell, a network coverage state of the first secondary cell, including: the cell evaluation device respectively determines average values of N target parameters in the measurement report data of the first auxiliary cell in the first duration according to the measurement report data of the first auxiliary cell; if the average value of M target parameters in the average value of N target parameters is larger than a corresponding preset threshold value, determining that the network coverage state of the first auxiliary cell is good; otherwise, determining that the network coverage state of the first auxiliary cell is problematic, wherein the preset threshold is a threshold for evaluating the network coverage state of the auxiliary cell, N and M are both positive integers, and N is greater than or equal to M.

For example, taking an anchor Cell as an LTE Cell, a secondary Cell as an NR Cell, a set duration of 50 seconds, and a period of a certain duration of 10 seconds as an example, table 2 is an example of measurement report data of NR Cell1 and measurement report data of one or more LTE cells that are doubly connected to NR Cell 1:

TABLE 2

Note that, in table 2, no data of 00:00:10 and 00:00:40 above assumes that NRCell1 is not dual connected with other LTE cells at 00:00:10 and 00:00:40.

In combination with table 2, it is assumed that there are 3 target parameters in the measurement report data of NRCell1, i.e., n=3, 3 target parameters are NRRSRP, NRRSRQ and NRRSRQ, respectively, where the average nrrsrp= (-90) +(-100) +(-90) +(-100) = -95, the average nrrsrq= (-4) +(-8) +(-4) +(-8) = -6, and the average nrsinr=10+2+10+2=6.

After determining the average value of 3 target parameters in the measurement report data of NRCell1, the cell evaluation device compares the average value of 3 target parameters with the corresponding threshold value for evaluating the coverage state of the secondary cell network. Taking NRRSRP with a threshold value of-105, NRRSRQ with a threshold value of-12, NRSINR with a threshold value of 0, m=2 as an example, average nrrsr= -95 > -105, average nrrsrq= -6 > -12, average nrsinr=6 > 0, that is, the average value of 3 target parameters in the average value of 3 target parameters is greater than the corresponding preset threshold value, so as to satisfy the condition that the average value of 2 target parameters in the average value of 3 target parameters is greater than the corresponding preset threshold value, therefore, the cell evaluation device can determine that the network coverage state of NRCell1 is good.

With regard to the above step S203, as a possible implementation, the cell evaluation device determines, according to measurement report data of one or more anchor cells that make a dual connection with the first secondary cell, a network coverage status of one or more anchor cells that make a dual connection with the first secondary cell, including: the cell evaluation device respectively determines average values of P target parameters in the measurement report data of a second anchor point cell in one or more anchor point cells which are in double connection with a first auxiliary cell according to the measurement report data of the second anchor point cell in the one or more anchor point cells which are in double connection with the first auxiliary cell, wherein the second anchor point cell is any one of the one or more anchor point cells which are in double connection with the first auxiliary cell; if the average value of the Q target parameters in the average value of the P target parameters is larger than the corresponding preset threshold value, determining that the network coverage state of the second anchor point cell is good; otherwise, determining that the network coverage state of the second anchor cell is problematic, wherein the preset threshold is a threshold for evaluating the network coverage state of the anchor cell, P and Q are both positive integers, and P is greater than or equal to Q.

For example, taking LteCell1 in table 2 as an example, in combination with table 2, it is assumed that there are 2 target parameters in the measurement report data of LteCell1, i.e., p=2, and that the 2 target parameters are LteRSRP and LteRSRQ, respectively, where average ltersrp= (-110) +(-120) = -115, and average ltersrq= (-12) +(-14) = -13.

After determining the average value of 2 target parameters in the measurement report data of the LteCell1, the cell evaluation device compares the average value of the 2 target parameters with a threshold value corresponding to the target parameters for evaluating the network coverage state of the anchor cell. Taking the threshold value of LteRSRP as-105, the threshold value of LteRSRQ as-12, and q=2 as an example, average ltersrp= -115 < -105, average ltersrq= -13 < -12, that is, the average value of 0 target parameters in the average value of 2 target parameters is greater than the corresponding preset threshold value, the condition that the average value of 2 target parameters in the average value of 2 target parameters is greater than the corresponding preset threshold value is not satisfied, so the cell evaluation device can determine that the network coverage state of LteCell1 is problematic.

The method for determining the network coverage status of the LteCell2 in table 2 by the cell evaluation device is similar to the method for determining the network coverage status of the LteCell1 in table 2 described above, and is not described in detail here.

As one possible implementation, the present application further provides another method to determine a network coverage status of one or more anchor cells that are dual-connected with the first secondary cell, specifically including: the cell evaluation device respectively determines average values of A target parameters in the measurement report data of one or more anchor cells in the first duration according to the measurement report data of one or more anchor cells which are in double connection with the first auxiliary cell, and if the average value of B target parameters in the average values of A target parameters is larger than a corresponding preset threshold value, the network coverage state of one or more anchor cells is determined to be good; otherwise, determining that the network coverage state of one or more anchor cells is problematic, wherein the preset threshold is a threshold for evaluating the network coverage state of the anchor cells, A and B are both positive integers, and A is greater than or equal to B. When the network coverage state of one or more anchor cells is determined to be problematic, if the value of the target parameter of a certain anchor cell in the measurement report data of one or more anchor cells is smaller than the corresponding threshold value, determining that the anchor cell is problematic.

For example, taking table 2 as an example, in combination with table 2, it is assumed that there are 2 target parameters for the LTE cell, i.e. a=2, 2 target parameters are LteRSRP, lteRSRQ respectively, where all LTE cells average ltersrp= (-110) +(-100) +(-110) +(-120) = -110, all LTE cells average ltersrq= (-12) +(-14) = -13.5.

After determining the average value of 2 target parameters in the measurement report data of the LteCell1, the cell evaluation device compares the average value of 2 target parameters with a threshold value corresponding to the target parameters for evaluating the coverage state of the LTE cell network. Taking the threshold value of the LTE cell LteRSRP as-105, the threshold value of the LTE cell LteRSRQ as-12, and b=2 as an example, the LTE cell average ltersrp= -110 < -105, the LTE cell average ltersrq= -13.5 < -12, that is, the average value of 0 target parameters in the average value of 2 target parameters is greater than the corresponding preset threshold value, and the condition that the average value of 2 target parameters in the average value of 2 target parameters is greater than the corresponding preset threshold value is not satisfied, the cell evaluation device can determine that the network coverage state of the LTE cell is problematic.

Further, after determining that the network coverage state of the LTE cell is problematic, the cell evaluation device may determine that the network coverage state of the LTE cell1 is problematic because the ltersrp= -110 of the LteCell1 is less than the corresponding preset threshold-105 and the ltersrq= -14 of the LteCell1 is less than the corresponding preset threshold-12. It should be noted that, if a target parameter of a certain anchor cell is smaller than a corresponding preset threshold, it can be determined that a problem occurs in the network coverage state of the anchor cell.
