Description

Cell grouping method and device Technical field

The present application relates to the field of communications, and in particular, to a cell grouping method and apparatus.

Background technique

In the field of communication, Time Division Duplexing (TDD) has played a huge role in communication technology in the past due to its time-domain staggering using the same frequency. In the fifth-generation mobile communication technology (English name: 5th-Generation, 5G) system, since the frequency band is greatly expanded to the high frequency band, the bandwidth of a single frequency point is increased, and it is very difficult to realize the symmetric frequency point, and the characteristics of TDD can be better. Meet the requirements of asymmetric services and adapt to 5G's more diverse and rich business needs.

For the TDD system, in order to avoid serious inter-base station and inter-UE interference, the uplink and downlink time slot ratios of adjacent cells must be the same. As shown in FIG. 1 , an architecture diagram of wireless communication is illustrated. Cell A is adjacent to cell B (same station or different station). If the uplink and downlink configurations of the two cells are inconsistent as shown in FIG. 2, a cell will appear. The downlink interferes with the uplink of the neighboring cell (as indicated by the broken line a in FIG. 1), and at the cell boundary, the uplink of one cell UE interferes with the downlink of the other cell (as indicated by a broken line b in FIG. 1).

In order to improve network utilization, adapt to the imbalance of cell services, and avoid the performance loss caused by strong cross-over interference in the TDD system, the 3rd Generation Partnership Project (3GPP) proposed a A packet-based interference coordination technique. The technology is based on Cell Cluster Interference Mitigation (CCIM), and the cells with low transmission loss or high inter-cell interference level are grouped into one group, and the transmission loss is large or the inter-cell interference level is higher. Small base stations are grouped into different groups. All the base stations in the group must be configured with the same TDD uplink-downlink subframe ratio configuration to avoid strong cross-interference. Different groups can be configured with different TDD uplink-downlink subframe ratio configurations. As shown in FIG. 3, the cells grouped by the CCIM technology, the packet 104, the packet 106, and the packet are illustrated. Each of the intra-packet cells in 108 must be configured to have the same TDD uplink-downlink subframe ratio configuration, and the packet 104, the packet 106, and the packet 108 can be configured to be configured with different TDD uplink-downlink subframe ratios.

However, in the case of densely deployed cells, inter-cell interference relationships are complex and interrelated, and it is difficult to clearly separate high-interference cell groups and low-interference cell groups. After CCIM technology, a large area may only be a group. The effective grouping is not reached, making the packet-based TDD subframe dynamic configuration inefficient. In addition, the cell grouping is considered only from the perspective of interference, and the service imbalance of different cells cannot be adapted, and the network utilization cannot be improved.

Summary of the invention

The embodiment of the present invention provides a cell grouping method and device, which implements a cell group that is effective and adapts to different cell service imbalances, thereby improving packet-based TDD subframe dynamic configuration efficiency and improving network utilization.

To achieve the above objective, the embodiment of the present application adopts the following technical solutions:

In a first aspect, an embodiment of the present application provides a cell grouping method, which is applied to a cell grouping device. The cell grouping device is deployed in a centralized control device in the network. The cell grouping method provided by the embodiment of the present application specifically includes: performing, by using an outer boundary connection line, a packet reference cell having the same uplink and downlink service type in the network, and obtaining N non-intersecting group boundary lines; Determining, by the set of cells to be inspected, the boundary cells of the cell group corresponding to the N group boundary lines, and obtaining the cell packet; wherein the capacity index of the packet reference cell satisfies a preset grouping condition; The service type corresponds to the service type; N is greater than or equal to 2; the set of cells to be inspected includes N cells intersected by the group boundary line and cells not surrounded by the N group boundary lines.

The cell grouping method provided by the embodiment of the present application, from the perspective of the cell service performance, first refers to the uplink and downlink service type and the capacity indicator of the cell, and the cell boundary with the same packet condition and the same uplink and downlink service type. The line group boundary line is obtained, and the preliminary cell grouping is obtained; and the group boundary to be inspected that is not completely surrounded by the group boundary line is determined according to the preset boundary cell determining rule, and the corresponding boundary line of each group is determined. The boundary cells of the block get the final grouping. In the whole grouping process, the cell grouping is performed based on the cell capacity, and the proportion of the uplink and downlink services on the actual network is considered, so that the proportion of the uplink and downlink services is different under the premise that the cell capacity is not compressed by the preset grouping conditions. Small cells are divided into one cell group. The introduction of traffic-based packets adapts to the imbalance of different cell services, avoids the compression of cell traffic and improves network utilization. At the same time, the actual downlink network service is combined with the actual downlink service ratio at the time of grouping, and the cells with different load-bearing services can be divided into the same group, thereby avoiding too many packet numbers, improving the validity of the packet, and thus improving the number of packets.

detailed description

The diversity of communication services leads to diversified uplink and downlink configurations in the actual network, and the interference caused by different uplink and downlink configurations of adjacent cells cannot be ignored. Based on this, the industry groups the cells by using the same uplink and downlink configuration to avoid interference. The inter-group cells use different uplink and downlink configurations, and the interference generated by the cells does not affect the user experience. According to this principle, a grouping method of CCIM is proposed, which is grouped based on the interference level. Due to the complexity of the actual network deployment, the interference of cells in the entire network is complex and interrelated, and it is difficult to define high interference or low interference, so that the CCIM scheme grouping effect is not obvious. Moreover, the interference-based packet cannot adapt to the imbalance of different cell services, and the original intention of the packet cannot be achieved.

Based on this, the basic principle of the present invention is that the reference traffic and the actual network service uplink and downlink ratio are grouped, so that the imbalance of different cell services is better adapted, so that the uplink and downlink configurations of the cell are better adapted to the services in the network.

The packet reference cells of the same uplink and downlink service type in the network are respectively connected to the outer boundary to obtain N non-intersecting group boundary lines. According to the preset boundary cell determination rule, N pieces are determined from the set of cells to be inspected.

The embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

The nouns used in the embodiments of the present invention are first explained as follows:

The preset grouping condition is a capacity measurement condition of a cell to be grouped based on the preset of the cell traffic amount. A cell whose capacity index satisfies the preset grouping condition is grouped. If the capacity is not packetized, the cell is compressed. If the capacity indicator does not satisfy the preset packet condition, the cell is not grouped.

The preset boundary cell determination rule is a preset cell determined from the set of cells to be inspected The rules of the group's boundaries.

In one aspect, the embodiment of the present application provides a cell grouping method, which may be performed by a cell grouping apparatus provided by an embodiment of the present application. The cell grouping apparatus may be deployed in an OSS, or may be deployed in other centrally controlled nodes. In the embodiment of the present application, the method for performing cell grouping by using the OSS is taken as an example, and the method provided by the present application is described, but is not limited to the execution subject of the cell grouping method provided by the embodiment of the present application. The actions performed by the OSS in the following embodiments are the actions performed by the cell grouping device.

As shown in FIG. 6, the cell grouping method may include:

S601. The OSS connects the packet reference cells of the same uplink and downlink service type in the network to the outer boundary, and obtains N non-intersecting group boundary lines.

Where N is greater than or equal to 2. The capacity indicator of the packet reference cell satisfies a preset grouping condition, and the packet reference cell is a cell in which the capacity indicator in the network satisfies a preset grouping condition. The uplink and downlink service type is the service type corresponding to the actual downlink traffic ratio of the cell.

Specifically, by determining the content of the grouping condition, the grouping principle may be determined, and the cell that determines the packet, that is, the packet reference cell, is determined. A cell whose capacity indicator satisfies a preset grouping condition is grouped; otherwise, no packet is performed. The packet is used as the packet reference cell, and the packet is not used as the packet reference cell. The packet reference cell determines the result of the packet.

It should be noted that the content of the preset grouping conditions may be set according to actual requirements, which is not specifically limited in this embodiment of the present application.

Optionally, the embodiment of the present application provides a preset grouping condition content, where the preset grouping condition may include: in the statistics of the previous one volume statistical period, the capacity index of the J capacity statistics period is greater than or equal to the capacity threshold. . Where I is greater than or equal to 1, and J is less than or equal to 1. The first I capacity statistics period refers to the continuous I capacity statistics period before the current time.

It should be noted that the specific values of I and J can be set according to actual requirements, which is not specifically limited in this embodiment of the present application. When statistics are counted in the capacity statistics period, you can select the most busy data record in the period, or you can select the period. The average value of the recording, or other manners, is not specifically limited in the embodiment of the present application.

Further, any indicator that can be used to measure the capacity of a cell can be used as a capacity indicator. Optionally, the capacity indicator may include a cell congestion rate, or the capacity indicator may include uplink or downlink PRB utilization, uplink or downlink power utilization, access failure rate, user experience rate failure rate, CPU usage, and the like. Wait. Certainly, the specific content of the capacity indicator may be set according to actual requirements, which is not specifically limited in this embodiment of the present application.

The cell congestion rate may include the number of TTIs when the cell schedules 90% PRB divided by the number of TTIs when the cell is busy.

Certainly, the specific definition of the cell congestion rate may also be set according to actual requirements, which is not specifically limited in this embodiment of the present application.

It should be noted that the capacity indicator of the cell may include an uplink capacity indicator of the cell and/or a downlink cell capacity indicator.

Optionally, when the capacity indicator of the cell includes the uplink capacity indicator of the cell and the cell capacity indicator of the downlink, the capacity indicator of the cell meets the preset grouping condition, and the line capacity indicator of the cell or the downlink capacity indicator meets the preset. According to the grouping condition, the capacity indicator of the cell satisfies the preset grouping condition.

Optionally, when the capacity indicator of the cell includes the uplink capacity indicator of the cell and the cell capacity indicator of the downlink, the capacity indicator of the cell satisfies the preset group condition, and the uplink capacity indicator and the downlink capacity indicator of the cell respectively satisfy the preset grouping condition. The capacity indicator of the cell satisfies the preset grouping condition.

It should be noted that the specific definition of the capacity indicator of the cell and the specific definition of the preset grouping condition may be set according to actual requirements, which is not specifically limited in this embodiment of the present application.

For example, the following is an example of determining a downlink reference rate of a cell according to a capacity indicator, and determining a packet reference cell according to a capacity indicator of a cell.

For example, the upper part of Table 1 shows the congestion rate statistics of 5 cells in the network over a period of time, and the capacity statistics period of the statistics is days. Under Table 1 In the half, the packet identity is used to identify whether the cell in each cycle is a packet reference cell. The packet identifier of the packet reference cell is "TURE", which is indicated as "T" in Table 1; the identifier of the non-packet reference cell is "FALSE", which is indicated as "F" in Table 1. The defined preset grouping condition is that if the 3 day capacity index is greater than the threshold within 7 consecutive days, the cell "service group identifier" is set to TRUE.

It can be seen from the data in Table 1 that in the period A, cell1, cell4, and cell5 are packet reference cells; in cycle B, cell4 and cell5 are packet reference cells; in cycle C, cell1, cell2, cell3, and cell5 are packet reference cells; The period D, cell 1, cell 2, cell 3, and cell 5 are packet reference cells.

It should be noted that the capacity statistics period in Table 1 is the same as the period of determining the packet reference cell, but in actual applications, the two may be different. This embodiment of the present application does not specifically limit this.

It should be noted that the above example and Table 1 are only by way of example, the capacity index of the cell, and the determination of the packet reference cell according to the capacity indicator are exemplified, not the cell capacity indicator, the preset grouping condition, and the determined grouping reference. The specific definition of the way of the cell.

Table 1

Specifically, at least one service type may be preset, and a preset service class is established. Correspondence between the type and the ratio of uplink and downlink traffic of the cell. After the statistics of the uplink and downlink services of the cell are obtained, the uplink and downlink service types of the cell are obtained. A cell that is equivalent to a cell service ratio or within a certain range is grouped as one type, so that cells of the same service type are divided into one cell group, and the same uplink and downlink configuration is used.

Among them, one service type corresponds to an interval of the ratio of uplink and downlink services. The corresponding relationship between the service type and the interval of the uplink and downlink service ratios may be set according to actual requirements, which is not specifically limited in this embodiment of the present application.

Optionally, the preset interval of the uplink and downlink traffic ratio corresponding to each service type may directly be a numerical threshold. Exemplarily, the threshold value of the interval of the uplink and downlink traffic ratio can be directly given, and is used to define a preset interval of the uplink and downlink traffic ratio corresponding to each service type, as shown in Table 2.

Exemplarily, as shown in Table 2, a correspondence between a service type and an uplink and downlink traffic ratio is illustrated.

It should be noted that Table 2 exemplifies the correspondence between the service type and the ratio of the uplink and downlink services by way of example, and is not specific to the correspondence between the service type and the ratio of the uplink and downlink services and the representation of the corresponding relationship. limited.

Table 2

business type	Upstream and downbound business ratio
Type 1	Greater than or equal to 5
Type 2	Greater than or equal to 3 and less than 5
Type 3	Greater than or equal to 1, and less than 3
Type 4	Less than or equal to 1

Optionally, the preset interval of the uplink and downlink services corresponding to each service type may be divided according to the uplink and downlink configurations supported by the actual product. Specifically, the process of dividing the interval of the uplink and downlink service proportions corresponding to each service type according to the uplink and downlink configuration supported by the actual product is not specifically limited in this embodiment, and is not described in detail.

Exemplarily, assume that the product supports four uplink and downlink configurations, which are 9:1, 3:1, respectively. 1:1, 1:3, the thresholds of different service types can be set to 4, 2, and 0.5. The interval of the proportion of uplink and downlink services corresponding to a specific service type can be as shown in Table 3.

table 3

business type	Upstream and downbound business ratio
Type 1	Greater than 4
Type 2	Greater than 2 and less than or equal to 4
Type 3	Greater than or equal to 0.5 and less than or equal to 2
Type 4	Less than 0.5

It should be noted that the foregoing Table 3 only exemplifies the correspondence between the service type and the ratio of the uplink and downlink services, and is not the correspondence between the service type and the ratio of the uplink and downlink services and the representation of the corresponding relationship. Specifically limited.

Further, the uplink and downlink service types described in S601 are the ratios of the actual cell data accumulation and the actual downlink data accumulation sum in the first X data statistics periods, and the corresponding service type. Where X is greater than or equal to 1.

It should be noted that the value of the X may be set according to actual requirements, which is not specifically limited in this embodiment of the present application. When statistic data is counted in the data statistics period, the data record of the busiest time in the period can be selected, or the average value record in the period can also be selected. Or, when the data is collected in the data statistics period, the recording may be performed in other manners, which is not specifically limited in this embodiment of the present application.

Further, in S601, performing outer boundary connection on at least one packet reference cell means connecting, as far as possible, a straight line to an outer edge of at least one packet reference cell in the map.

Exemplarily, as shown in FIG. 7, it is assumed that the packet reference cell of type 1 and the packet reference cell of type 2 are the packet reference cells labeled in FIG. 7, and the outer boundary is connected, as indicated by the dotted line in FIG.

Further, in S601, the packet reference cells of the same uplink and downlink service type in the network are respectively connected to the outer boundary to obtain N non-intersecting group boundary lines, which may exist and not be limited in the actual solution application. Three cases:

In the first case, the packet reference cell with the same uplink and downlink traffic type is external. After the boundary is connected, the resulting group boundary line has no intersection.

In the first case, after the outer boundary is connected, there are a plurality of outer boundary lines without intersections, that is, N non-intersecting group boundary lines obtained in S601.

The outer boundary line in the first case will be described below in conjunction with the example. As shown in FIG. 8, it is assumed that the packet reference cell of type 1 is cell 1, cell 2, and cell 3. The group boundary line obtained after the outer boundary connection is shown by the dotted line in FIG. 8; the packet reference cell of type 2 is the cell. 4. Cell 5, cell 6, and cell 7, the group boundary line obtained after the outer boundary is connected is shown by the solid line in FIG. As can be seen from Fig. 8, the dotted line does not cross the solid line, so that two group boundary lines without intersection are obtained, that is, the broken line and the solid line in Fig. 8.

In the second case, after the outer boundary is connected to the packet reference cell with the same uplink and downlink service type, at least one of the obtained group boundary lines intersects.

In the second case, after the outer boundary is connected, there are a plurality of intersecting group boundary lines, and a second connection is required to obtain N non-intersecting group boundary lines.

The outer boundary line in the second case will be described below in conjunction with the example. As shown in FIG. 9, it is assumed that the packet reference cell of type 1 is cell A, cell B, cell C, and cell D, and the group boundary line obtained after the outer boundary is connected is indicated by a broken line in FIG. 9; The cell is the cell E, the cell F, the cell G, and the cell H. The group boundary line obtained after the outer boundary is connected is shown by the solid line in FIG. As can be seen from Figure 9, the dotted line intersects with the solid line, and the second connection is made. The type 2 area is re-wired with the cell A as the fulcrum, ensuring that the two groups of boundary lines no longer cross, and the two obtained. The group boundary lines without intersections are the dashed lines and solid lines as illustrated in FIG.

In the third case, after the outer boundary is connected to the packet reference cell with the same uplink and downlink service type, another group boundary line exists inside one group boundary line.

In the third case, after the outer boundary is connected, a plurality of outer boundary lines are obtained, and the outer boundary lines surrounded by the other group boundary lines are removed, and the remaining group boundary lines are N non-intersecting groups obtained in S601. borderline. It is only a group boundary line that is completely enclosed inside another set of boundary lines, and is directly used as a cell group (independent cell group), and a cell group corresponding to a large boundary line surrounding the group boundary line does not include the single cell. Single community group.

The outer boundary line in the third case will be described below in conjunction with the example. As shown in FIG. 11, it is assumed that the packet reference cell of type 1 is cell A ^, cell B ^, and cell C ^, and the group boundary line obtained by connecting the outer boundary is indicated by a broken line in FIG. 11; after the cell group is a cell boundary line ^E,, cell ^F,, cell ^G,, cell ^H,, cell ^I,, for connecting the outer boundary obtained is shown in solid lines in FIG. 11; refer to the packet type cell is a cell 3 R, cell S, cell T, and cell G, the group boundary line obtained after the outer boundary is connected is shown by the virtual real interval line in FIG. As can be seen from FIG. 11, the virtual real interval line is completely surrounded by the solid line, and the obtained two non-intersecting group boundary lines are as shown by the dotted line and the solid line in FIG. The type 3 packet reference cell is a cell group of cell R, cell S, cell T, and cell G.

It should be noted that, when S601 is executed, other situations than the above three cases may be included, but all the processes for obtaining N non-intersecting group boundary lines belong to the execution plan of S601, and all belong to the present application. The scope of protection.

S602: The OSS determines, according to the preset boundary cell determination rule, a boundary cell of the cell group corresponding to the N group boundary lines from the to-be-reviewed cell set, to obtain a cell grouping.

Specifically, in S601, the cells in the network are initially grouped based on the service (that is, the cells completely surrounded by the group boundary line in S601 are divided into a single cell group in the preliminary grouping phase), and the group in S601 is not grouped. The cell completely surrounded by the boundary line is used as the cell to be inspected, and the boundary lines of each group are gradually expanded according to the preset boundary cell determination rule until each cell in the cell to be inspected is allocated, so that each cell in the network can belong to the network. To the only one group.

The set of cells to be inspected includes a cell spanned by N group boundary lines and a cell not surrounded by N group boundary lines.

Specifically, the cell group corresponding to the group boundary line refers to a cell group to which the cell including the group boundary line is completely surrounded. After the boundary cell of the cell group is determined from the set of cells to be inspected, each cell in the set of cells to be inspected is also divided into the cell group corresponding to each group boundary line, so that each cell in the network belongs to In the only cell group, the cell grouping in the network is completed.

The preset boundary cell determining rule is a preset method for determining a boundary cell from the cell to be inspected. The pre-set principle can be obtained from the perspective of purpose.

Optionally, the specific content of the preset boundary cell determination rule may be configured by using the basic principle to avoid interference. When the interference avoidance is the basic principle in S602, the respective group boundary lines obtained in S601 are gradually expanded outward according to the interference avoidance principle in S602 until the division of each cell in the cell to be inspected is completed. Therefore, the specific content of the preset boundary cell determination rule can be configured as a basic principle to avoid interference.

Further, the group boundary line is gradually expanded outward, and may be specifically implemented as an epitaxial group boundary line. The cell that is finally surrounded by the group boundary line is a cell group, and may also be specifically implemented as a boundary cell for determining the initially divided cell group. The cell surrounded by the group boundary line plus the boundary cell of the cell group obtains the cell group. Only the latter description will be made in the embodiments of the present application, but is not intended to limit the specific process. The manner in which the ungrouped cells are further grouped based on the pre-defined boundary cell determination principle is the protection scope of the present application.

Specifically, when the specific content of the preset boundary cell determination rule is configured to prevent the interference as a basic principle, the preset boundary cell determination rule may include, but is not limited to, the following two solutions:

First plan,

The preset boundary cell determining rule is: according to the neighboring cell interference between the cell in the set of cells to be inspected and the neighboring cell, the cell pair whose neighboring cell interference satisfies the interference cancellation condition is divided into one cell group, and the boundary of the cell group is determined.

Optionally, the neighboring cell interference between the cell in the set of the cell to be inspected and the neighboring cell may be obtained by the neighboring cell measurement, the terminal reporting, or the like, which is not specifically limited in this embodiment, and any neighbor may be obtained. The method of regional interference can be applied to the present application as a reference for confirming the boundary cell. The specific process of acquiring the neighboring cell interference between the cell and its neighboring cell is not described in detail in this embodiment of the present application.

The interference cancellation condition is a preset critical interference condition that affects network performance. Optionally, the interference cancellation condition may include: in the first M interference statistical periods, Q The neighboring interference in the interference statistical period is greater than or equal to the interference threshold. Where M is greater than or equal to 1, and Q is less than or equal to M.

Alternatively, the neighbor interference may include a noise floor rise or a generated interference spur value. Alternatively, the neighboring cell interference may be other parameters for measuring the amount of interference, which is not specifically limited in this embodiment of the present application.

It should be noted that the specific values of M and Q may be set according to actual requirements, which is not specifically limited in this embodiment of the present application. When the statistics are collected in the interference statistics period, the data record in the most busy period of the period may be selected, or the average value in the period may be selected, or recorded in other manners, which is not specifically limited in the embodiment of the present application.

Exemplarily, assuming that the interference statistical period is days, the upper part of Table 4 indicates the neighboring area interference statistics between the cells in the network for a period of time, and the “1-2” in Table 4 refers to the pair of cells 2 Neighbor interference generated by cell 1. In the lower half of Table 4, the interference flag is used to identify whether the interference cancellation condition is met. The interference cancellation condition is defined as the 3D threshold for 3 days in a row for more than 7 days. The interference cancellation condition is satisfied, and the interference flag is recorded as “T”, otherwise the interference flag is recorded as “F”.

Table 4

It should also be noted that the above examples and Table 4 are only examples, not interference. Eliminate the specific limitations of conditions such as conditions and interference signs.

The following describes the boundary of the cell group corresponding to the N group boundary lines from the set of cells to be inspected according to the preset boundary cell determination rule in S602, according to the specific situation, when the preset boundary cell determination rule is the first scenario. The implementation of the cell.

Further, if, in the foregoing first solution, S602 is performed for each cell in the cell to be examined, then in S602, according to the preset boundary cell determination rule, the N group boundary lines are determined from the set of cells to be inspected. The implementation manner of the boundary cell of the cell group may include, but is not limited to, the following three situations:

Case 1. If the first cell in the set of cells to be inspected only meets the interference cancellation condition with the neighboring cell interference between the cells in the cell group corresponding to the first group of boundary lines, the first cell is used as the cell corresponding to the first group of boundary lines. Group of border cells.

The first cell is any cell between the first group boundary line and any other boundary line in the set of cells to be inspected; the first group boundary line is any one of the N group boundary lines.

Illustratively, as shown in FIG. 12, the solid line group boundary line and the dashed line group boundary line in FIG. 12 which have been wired are illustrated. It is assumed that the process of S602 is performed on the cell a in the cell combination to be inspected shown in FIG. 12, and the neighboring cell interference between the cell b in the cell group corresponding to the boundary group of the cell line and the boundary group of the solid line group satisfies the interference cancellation condition. For the interference, the cell a is used as the boundary cell of the cell group corresponding to the boundary group of the real line group, that is, the cell a is divided into the cell group corresponding to the boundary line of the solid line group.

Case 2: if the neighboring cell between the second cell in the set of cells to be inspected and the at least two cells in the cell group corresponding to the different group boundary line satisfy the interference cancellation condition, the second cell is used as the second group boundary line indication. The boundary cell of the cell group.

The second set of boundary lines is at least two cells, and completely surrounds a group boundary line of a cell that has the greatest interference to the second cell.

Exemplarily, based on the division scenario shown in FIG. 12, it is assumed that after S602 is performed on the cell a in the above case 1, the process of S602 is performed on the cell c. If the cell d in the cell group corresponding to the boundary line of the cell c and the boundary group of the solid line group and the cell e in the cell group corresponding to the boundary group of the dotted line group satisfy the interference cancellation condition, and the cell c and If the neighboring cell interference between the cell e is greater than the neighboring cell interference between the cell c and the cell d, the cell c is used as the boundary cell of the cell group corresponding to the boundary group of the dotted line group, that is, the cell c is divided into the dotted line group. Within the cell group corresponding to the boundary line.

Case 3: If the neighboring cell interference between the third cell in the cell set to be inspected and the cell in the cell group corresponding to any group boundary line does not satisfy the interference cancellation condition, the third cell is regarded as the third group boundary line. The boundary cell of the cell group, or the boundary cell of the cell group indicated by the third cell as the fourth group boundary line.

The third group boundary line and the fourth group boundary line are any one of the N group boundary lines, and the third cell is the set of the cells to be inspected, and is located at the third group boundary line and the fourth group boundary line. Any cell in between.

Exemplarily, based on the divided scenario shown in FIG. 12, it is assumed that after S602 is performed for the cell a in the above case 1, and S602 is performed for the cell c in the above case 2, the process of S602 is performed on the cell f. If the neighboring cell interference between the cells in the cell group corresponding to the boundary line of any one of the cells in FIG. 12 does not satisfy the interference cancellation condition, the cell f is used as the boundary cell of the cell group corresponding to the boundary group of the dotted group, that is, It is said that the cell f is divided into the cell group corresponding to the boundary group of the dotted group group, or the cell f is the boundary cell of the cell group corresponding to the boundary group of the solid line group, that is, the cell f is divided into the boundary line of the solid line group. Within the corresponding cell group.

Further, if, in the foregoing first solution, each of the cells in the cell to be compared in parallel performs S602, the cell pair in which the neighboring cell interference satisfies the interference cancellation condition is first taken as a whole according to the neighboring cell interference in S602. Then, according to the preset boundary cell determining rule, the boundary cells of the cell group corresponding to the N group boundary lines are determined from the set of cells to be inspected. Specifically, the cell pair that satisfies the interference cancellation condition of the neighboring cell as a whole, according to the preset boundary cell determining rule, determines a boundary cell of the cell group corresponding to the N group boundary lines from the set of cells to be inspected, and The above three cases are similar, except that the whole is regarded as a cell comparison preset boundary cell determination rule, and when a whole is regarded as a group boundary line corresponding to the boundary group of the cell group, the whole cell which is far away from the boundary line of the group is The boundary cell corresponding to the cell group of the group boundary line.

Illustratively, as shown in FIG. 13, the actual implementation in FIG. 13 that has been wired is illustrated. Line group boundary line and dashed line group boundary line. It is assumed that the neighboring interference between the cell a and the cell b and the cell c in the set of cells to be examined shown in FIG. 13 both satisfy the interference cancellation condition, and therefore, the cell a, the cell b, and the cell c are regarded as a whole. It is further assumed that the neighboring interference between the cell d in the cell group corresponding to the boundary line of the cell b and the boundary group of the solid line group satisfies the interference cancellation condition, and the boundary line of the solid line group in the whole of the cell a, the cell b, and the cell c is the most The far cell a is the boundary cell of the cell group corresponding to the boundary group of the solid line group, that is, the cell a, the cell b, and the cell c are divided into the cell groups corresponding to the boundary group of the solid line group.

plan B,

The preset boundary cell determining rule is: determining, according to the location relationship between the cell and the group boundary line in the set of cells to be inspected, the cell in the set of cells to be inspected is the boundary cell of the cell group corresponding to the closest group boundary line.

Further, if the cell to be inspected does not include a cell that is completely not surrounded by the group boundary line, and only includes the cell that the group boundary traverses, the cell in the cell to be inspected is the boundary of the cell group corresponding to the group boundary line of the group. Community.

It should be noted that the content of the preset boundary cell determination rule may be configured according to actual requirements, and is not limited to the foregoing two solutions. Any method for determining a boundary cell from a cell to be inspected according to a preset boundary cell determination rule belongs to the scope of protection of the present application.

The cell grouping method provided by the embodiment of the present application, from the perspective of the cell service performance, first refers to the uplink and downlink service type and the capacity indicator of the cell, and the cell boundary with the same packet condition and the same uplink and downlink service type. The line group boundary line is obtained, and the preliminary cell grouping is obtained; and the boundary cell of the cell group corresponding to each group boundary line is determined according to the preset boundary cell determining rule from the set of the to-be-checked cells that are not completely surrounded by the group boundary line, and finally Grouping of groups. In the whole grouping process, the cell grouping is performed based on the cell capacity, and the proportion of the uplink and downlink services on the actual network is considered, so that the proportion of the uplink and downlink services is different under the premise that the cell capacity is not compressed by the preset grouping conditions. Small cells are divided into one cell group. Introduce traffic-based packets, adapt to the imbalance of different cell services, and try to avoid small The compression of the area traffic increases the network utilization. At the same time, the actual downlink network service is combined with the actual downlink service ratio at the time of grouping, and the cells with different load-bearing services can be divided into the same group, thereby avoiding too many packet numbers, improving the validity of the packet, and thus improving the number of packets. Packet-based TDD subframe dynamic configuration efficiency and commercial implementability of the scheme.

Optionally, as shown in FIG. 14 , in the S601, the OSS sends the packet reference cells of the same uplink and downlink service type in the network to the outer boundary to obtain the N non-intersecting group boundary lines. The cell grouping method may further include S601a.

S601a and OSS collect the capacity index of each cell in the network according to the capacity statistics period.

In S601a, the OSS may use the method of requesting reporting to calculate the capacity index of each cell in the network, or the method of periodically reporting the capacity indicator in each cell to implement the function of the S601a. This is not specifically limited.

Specifically, when the OSS uses the method of requesting reporting to calculate the capacity indicator of each cell in the network, the OSS periodically sends a capacity indicator request message to each cell, and each cell receives the request message. After measuring the current capacity indicator of the current cell, the OSS feeds back a response message including the current capacity indicator.
