Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the field of communications, and in particular to a method for configuring a cooperative relationship of communication cells, a network device, and a storage medium. Background Art
[0002] Array antenna base stations have been commercialized on a large scale in mobile communication networks. With the rise of 4G+ (Pre-5G) and 5G networks in recent years, the application of Massive MIMO technology has also shown a blowout trend. Traditional array antenna base stations can control the direction and width of the transmission beam in the horizontal dimension, while Massive MIMO consists of more transmitting units and can control the direction and width of the beam in the horizontal and vertical degrees of freedom. The characteristics of array antennas and Massive MIMO antennas that can flexibly control the transmission pattern also provide convenience for network self-optimization, giving rise to the broadcast beam transmission pattern adaptation technology. This broadcast beam transmission pattern adaptation technology reduces co-channel interference, tracks the breathing effect of the cell, improves the network capacity and user experience in the area, and reduces the network operation and maintenance costs. The adaptive adjustment of the antenna pattern of the array antenna / Massive MIMO base station is divided into two major processes: AAPC coordination relationship / coordination group configuration and AAPC weight adaptation. When the AAPC function is enabled, the coordination relationship / coordination group must be configured first before the adaptive configuration and adjustment of the inter-cell antenna pattern can begin.
[0003] In the process of implementing the embodiments of the present invention, the inventors found that: currently, the cell coordination group is manually configured, and the process of manually configuring the cell coordination group is roughly as follows: the operation and maintenance personnel manually select N cells that need to be coordinated in the network to form a coordination group based on the network key performance indicators and system processing capabilities, and manually configure the coordination relationship between the N cells in the coordination group. The manually selected cell coordination group is affected by the personal views of the person, and the selection criteria are affected by personal factors; and it requires additional labor costs, which increases the configuration cost and reduces the efficiency of network optimization. Summary of the invention
[0004] The purpose of the embodiments of the present invention is to provide a method for configuring a cooperative relationship between communication cells, a network device and a storage medium, which can improve the configuration efficiency of the cooperative relationship between communication cells and reduce the configuration cost.
[0005] To achieve the above-mentioned purpose, an embodiment of the present application provides a method for configuring a collaborative relationship between communication cells, which is applied to a target communication cell to be optimized, and the method comprises: selecting an associated cell associated with the target communication cell from an initial collaborative set, wherein the target communication cell and the associated cell both belong to the initial collaborative set, and the initial collaborative set includes at least one of the target communication cells in the target area; and configuring the collaborative relationship between the target communication cell and the associated cell.
[0006] To achieve the above-mentioned purpose, an embodiment of the present application also provides a method for configuring a collaborative relationship between communication cells, comprising: obtaining a measurement group matching a specified type, the measurement group including at least one target communication cell to be optimized; traversing and searching for the same-frequency neighboring cells of each target communication cell in the measurement group, and updating the measurement group according to the searched same-frequency neighboring cells until a preset condition is met; using the updated measurement group as an initial collaborative set, so that the target communication cell can obtain associated associated cells from the initial collaborative set, and configure the collaborative relationship between the target communication cell and the associated cells; the preset conditions include: the types of the searched same-frequency neighboring cells are not the specified types, or the number of the target communication cells of the specified type in the measurement group exceeds a preset fourth threshold, or the number of communication cells in the measurement group exceeds a preset fifth threshold.
[0007] To achieve the above-mentioned purpose, an embodiment of the present application also provides a network device, including: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the above-mentioned method for configuring the collaborative relationship of communication cells.
[0008] To achieve the above objectives, an embodiment of the present application further provides a computer-readable storage medium storing a computer program, which implements the above method for configuring the collaborative relationship of communication cells when executed by a processor.
[0009] The method for configuring the cooperative relationship of communication cells proposed in the present application comprises an initial cooperative set including at least one target communication cell in the target area, an associated cell associated with the target communication cell is obtained from the initial cooperative set, and a cooperative relationship is configured with the associated cell. Since the number of cells to be configured with the cooperative relationship is reduced in advance, the configuration speed is improved; the cooperative relationship between the target communication cell and the associated cell is configured by obtaining the associated cell instead of manually selecting the cell, so that the determined associated cell is more objective, and the problem of configuring the cooperative relationship for the cell with low correlation degree and thus wasting configuration resources is avoided, and the accuracy of the cooperative relationship configuration is improved. At the same time, since there is no need to manually configure the cooperative relationship between the target communication cell and the associated cell, the efficiency of configuring the cooperative relationship is improved and the labor cost is saved.

[0018] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.
[0019] Currently, the coordination group of communication cells is manually selected, and the coordination relationship is configured between the communication cells in the coordination group. However, with the increase in cell types, the configuration of the coordination relationship between cells of different types and the coordination relationship between cells of the same type will become more complicated. If manual configuration is still used, it will be very labor-intensive and inefficient. When the network structure changes or there is a change in the business, the coordination relationship needs to be reconfigured, resulting in slow and inefficient configuration of the coordination relationship.
[0020] The first embodiment of the present invention relates to a method for configuring a communication cell coordination relationship, the process of which is as follows: Figure 1 As shown:
[0021] Step 101: selecting an associated cell associated with a target communication cell from an initial coordination set, wherein both the target communication cell and the associated cell belong to the initial coordination set, and the initial coordination set includes at least one target communication cell in a target area;
[0022] Step 102: Configure the coordination relationship between the target communication cell and the associated cells.
[0023] In an embodiment of the present invention, the initial collaborative set includes at least one target communication cell in the target area. The target communication cell obtains associated associated cells from the initial collaborative set and configures a collaborative relationship with the associated cells. Since the number of cells to be configured with collaborative relationships is reduced in advance, the configuration speed is improved. The collaborative relationship between the target communication cell and the associated cells is configured by obtaining associated cells instead of manually selecting cells. This makes the determined associated cells more objective, avoids the problem of configuring collaborative relationships for cells with low association and thus wasting configuration resources, and improves the accuracy of collaborative relationship configuration. At the same time, since there is no need to manually configure the collaborative relationship between the target communication cell and the associated cells, the efficiency of configuring the collaborative relationship is improved and labor costs are saved.
[0024] The second embodiment of the present invention relates to a method for configuring a communication cell coordination relationship. The second embodiment is a detailed introduction of steps 101 to 102 in the first embodiment. The process is as follows: Figure 2 shown.
[0025] Specifically, the method for configuring the communication cell coordination relationship is applied to a network device, which may be a communication cell device, such as a base station device, and the target communication cell automatically configures the coordination relationship with other communication cells.
[0026] Step 201: Select an associated cell associated with a target communication cell from an initial coordination set.
[0027] In one example, an initial collaborative set can be obtained through a network device for managing communication cells. The initial collaborative set includes N target communication cells in the target area, where N is an integer greater than 0. Among them, the target communication cells include: traditional array antenna cells and / or large-scale array antenna cells. The target area may be a business-intensive area, such as a business district, a subway station, a railway station, etc.; the target area may be manually pre-set. The process of obtaining the initial collaborative set may be to select any target communication cell in the target area, and to collect the communication cells in the preset radius area with the selected target communication cell as the center. For example, the target communication cell located in the center of the target area searches for other communication cells within the preset radius, and the combination of the searched other communication cells and the target communication cell currently located in the center of the target area is the initial collaborative set; it may also be to collect the combination of the target communication cells in the specified area in the target area as the initial collaborative set. It can be understood that the initial collaborative set may also be manually determined according to the network KPI indicator, and sent to the network device by the human through the device.
[0028] It should be noted that the initial coordinated set includes at least one target communication cell, and the initial coordinated set may also include other communication cells, including: communication cells other than large-scale array antenna cells and array antenna cells, such as macro cells.
[0029] The initial coordination set may include multiple target communication cells. In this example, a target communication cell is taken as an example to introduce the process of configuring the coordination relationship between the target communication cell and the associated cells.
[0030] Specifically, the associated cell associated with the target communication cell can be selected from the initial coordination set by: Figure 3 Steps shown.
[0031] Step S21: Obtain overlapping coverage information between the target communication cell and at least one target co-frequency neighboring cell from the initial coordination set, where the target co-frequency neighboring cell is the co-frequency neighboring cell of the target communication cell.
[0032] In one example, a measurement instruction is sent to each terminal in a target communication cell so that the terminal reports service measurement data belonging to the service cell and neighboring area measurement data belonging to a target co-frequency neighboring area; it is determined whether a first quantity value of the service measurement data received within a preset time period exceeds a preset first threshold value, and if so, overlapping coverage information between the target communication cell and at least one target co-frequency neighboring area is generated based on the first quantity value and a second quantity value of the neighboring area measurement data; otherwise, measurement instructions are continued to be sent to each terminal until the quantity value of the received service measurement data exceeds the first threshold value.
[0033] Specifically, the preset duration can be set according to actual needs. For example, the preset duration can be a duration of 24 hours, which can be counted by a timer.
[0034] Within a preset time period, a measurement instruction is issued to all user terminals (User Equipment, UE) of the current target communication cell. All user terminals of the communication cell include UEs located in the current target communication cell, which may also be newly accessed UEs, UEs that have switched access, and UEs that have reestablished access to the current communication cell. The measurement instruction is used to instruct the terminal to perform a specified measurement task, for example, a measurement report (Measurement Report, MR) measurement task. The UE performs the measurement task according to the received measurement instruction and reports the collected measurement data to the communication cell. The measurement data includes service measurement data belonging to the service cell and neighboring cell measurement data belonging to the target co-frequency neighboring cell; a counter can be used to record the number of times the terminal reports the service measurement data of the service cell and the number of times the terminal reports the neighboring cell measurement data, and obtain a first quantity value of the service measurement data and a second quantity value of the neighboring cell measurement data of the target co-frequency neighboring cell.
[0035] In one example, the following processing is performed for each received service measurement data: determine whether the specified data in the service measurement data is greater than a preset threshold, and if it is greater than the preset threshold, increase the first quantity value of the statistic. The specified data may include the received strength of the signal or the received quality of the signal. For example, the specified data is MR data, and the MR data may be RSRP, RSRQ, and other types of measurement data. This embodiment is described by taking RSRP as an example, including the RSRP of the service cell of the UE mobile phone and the RSRP data of all co-frequency neighboring cells of the service cell.
[0036] Specifically, the process of counting the first quantity value is as follows: compare the RSRP data of the target communication cell reported by each UE with the preset first threshold SerCellRsrpThre, if the RSRP of the target communication cell is greater than the threshold, then the value of the measurement counter SerCellOverlapCnt(m) of the cell is increased by 1. Wherein m represents the mth target communication cell in the initial collaborative set, and SerCellOverlapCnt(m) represents the number of times the mth target communication cell in the initial collaborative set receives the service measurement data of the target communication cell reported by the terminal.
[0037] The process of counting the second quantity value is to perform the following operation on the RSRP of each reported target co-frequency neighboring cell: compare the difference between the RSRP of the target co-frequency neighboring cell reported by the UE and the RSRP of the serving cell reported by the UE with the preset second threshold DiffRsrpThre; if the difference is greater than the threshold, then the value of the measurement counter AdjCellOverlapCnt(m,n) of the target co-frequency neighboring cell is increased by one, wherein n represents the nth target co-frequency neighboring cell of the cell, and each target co-frequency neighboring cell is counted separately, and (m,n) represents the nth target co-frequency neighboring cell in the mth target communication cell in the initial collaborative set; AdjCellOverlapCnt(m,n) represents the number of neighboring cell measurement data of the nth target co-frequency neighboring cell reported by the terminal received in the mth target communication cell in the initial collaborative set.
[0038] After the detection reaches the preset time length, determine whether the first quantity value of the MR data of the target communication cell obtained exceeds the preset first threshold value RsrpSampleNumThre. If so, stop sending the measurement instruction to the terminal, and generate the overlapping coverage information between the target communication cell and at least one target co-frequency neighboring area according to the first quantity value and the second quantity value. If the number of measured data does not reach the first threshold value RsrpSampleNumThre after the preset time length is reached, keep sending the measurement instruction, continue to receive the service measurement number reported by the terminal, until the first quantity value of the service measurement number exceeds the first threshold value, and stop sending the measurement instruction.
[0039] It is worth mentioning that the target same-frequency neighboring cell mentioned in this embodiment may include a target same-frequency switching neighboring cell.
[0040] In one example, the process of generating overlapping coverage information between a target communication cell and at least one target co-frequency neighboring cell based on a first quantity value and a second quantity value of neighboring cell measurement data may be: determining whether the second quantity value is greater than a preset second threshold value, and if so, obtaining the ratio between the second quantity value and the first quantity value, and using the ratio as the overlapping coverage information between the target communication cell and the target co-frequency neighboring cell.
[0041] Specifically, the calculation process for the overlapping coverage information between the current target communication cell and any target co-frequency neighboring cell is as follows: compare the value of the measurement counter AdjCellOverlapCnt(m,n) of the co-frequency neighboring cell with the preset second threshold MinSampleNumber. If the value of AdjCellOverlapCnt(m,n) is greater than the second threshold, obtain the ratio between the neighboring cell measurement data and the service measurement data, and use the ratio as the overlapping coverage information between the target communication cell and the target co-frequency neighboring cell.
[0042] For example, the current target communication cell is the 0th target communication cell in the initial coordinated set. The number of target co-frequency neighboring cells of the target communication cell is 3. The subscripts of the target co-frequency cells are 0, 1, and 2, respectively. That is, (0,0) represents the 0th target co-frequency cell of the 0th target communication cell in the initial coordinated set. The value of AdjCellOverlapCnt(1,0) is 100, indicating that the number of times the terminal reports the target co-frequency neighboring cell is 100. The value of AdjCellOverlapCnt(1,1) is 1000. AdjCellOv The value of erlapCnt(1,2) is 800; the second threshold is 500; the value of SerCellOverlaspCnt(1) is 3000, indicating that the number of times the first target communication cell in the initial collaborative set is reported is 3000; it can be seen that AdjCellOverlapCnt(1,1) is greater than the second threshold, and the overlapping coverage ratio between the target communication cell 1 and the target co-frequency cell labeled (1, 1) = AdjCellOverlapCnt(1,1) / SerCellOverlaspCnt(1).
[0043] The overlapping coverage ratio between the target communication cell and at least one target co-frequency adjacent cell is calculated as the acquired overlapping coverage information.
[0044] Step S22: Select the target co-frequency neighboring cell corresponding to the overlapping coverage information that meets the first selection condition.
[0045] Specifically, the first selection condition is set according to actual needs. For example, the first selection condition is to select a target co-frequency neighboring area corresponding to overlapping coverage information.
[0046] It should be noted that the type of the target co-frequency neighboring cell of the target communication cell may be the target communication cell or other communication cells.
[0047] Step S23: Obtain associated cells according to the selected target co-frequency neighboring cells.
[0048] If the number of selected target co-frequency neighboring cells is at least 2, then at least two overlapping coverage information can be sorted to obtain a first sorting result; based on the first sorting result and a preset number, the associated cells are determined one by one, wherein the preset number is set according to the processing capability of the network device.
[0049] Specifically, the obtained overlapping coverage information can be sorted from large to small to obtain the first sorting result of the overlapping coverage information. The overlapping coverage information can also be sorted from small to large to obtain the first sorting result. In this example, the overlapping coverage rate is sorted from large to small to obtain the first sorting result. In the first sorting result, the corresponding target co-frequency neighboring areas are sequentially used as associated cells in the order of overlapping coverage rate from large to small. If it is detected that the total number of target communication cells with an associated relationship determined in the initial collaborative set is less than the preset number b1, b1 is an integer greater than 1, then the next target co-frequency neighboring area of the type of the target communication cell in the first sorting result is continued to be used as the associated cell of the target communication cell; if it is detected that the total number of communication cells with an associated relationship determined in the initial collaborative set is less than the preset number b2, b2 is an integer greater than 1, then the next target co-frequency neighboring area of the type of other communication cells in the first sorting result is continued to be used as the associated cell of the target communication cell. This continues until all target co-frequency neighboring cells are selected as associated cells; or until it is detected that the total number of target communication cells with determined association relationships in the initial collaborative set is greater than or equal to the preset number b1 and the total number of communication cells with determined association relationships is greater than or equal to the preset number b2.
[0050] Step 202: Configure the coordination relationship between the target communication cell and the associated cells.
[0051] Specifically, the coordination relationship between the target communication cell and the associated cell is configured according to the configuration method of the coordination relationship.
[0052] It should be noted that if all target co-frequency neighboring cells are selected as associated cells and configured with a collaborative relationship, and it is detected that the total number of all target communication cells configured with a collaborative relationship in the initial collaborative set is less than the preset number b1, continue to execute steps 201 to 202 for the next target communication cell until all target communication cells in the initial collaborative set are traversed, or until the total number of all target communication cells currently configured with a collaborative relationship in the initial collaborative set is greater than or equal to the preset number b1 and the total number of communication cells configured with a collaborative relationship is greater than or equal to the preset number b2.
[0053] Step 203: Acquire other cooperative relationships that are mutually related to the cooperative relationship, so that the target communication cell and the associated cell in the mutually related cooperative relationships are combined into a cooperative group.
[0054] Specifically, according to the collaborative relationship, the collaborative relationship with the same target communication cell is searched, and the collaborative relationship found is used as a mutually related collaborative relationship. For example, there is a collaborative relationship 1 between the target communication cell MM 1 and the target communication cell MM2, there is a collaborative relationship 2 between the target communication cell MM2 and the target communication cell MM3, there is a collaborative relationship 3 between the target communication cell MM3 and the target communication cell MM4, and there is a collaborative relationship 4 between the target communication cell MM5 and the target communication cell MM6; the collaborative relationship 1 and the collaborative relationship 2 have the same target communication cell MM2, the collaborative relationship 2 and the collaborative relationship 3 have the same target communication cell MM3, and the target communication cell in the collaborative relationship 4 is different from the target communication cells in other collaborative relationships, so the collaborative relationship 1, the collaborative relationship 2 and the collaborative relationship 3 are mutually related, and the collaborative relationship 1, the collaborative relationship 2 and the collaborative relationship 3 are selected.
[0055] The network equipment used to manage communication cells can combine the target communication cells and associated cells in mutually related cooperative relationships into a cooperative group, wherein the target communication cell MM 1 has a cooperative relationship 1 with the target communication cell MM2, the target communication cell MM2 has a cooperative relationship 2 with the target communication cell MM3, the target communication cell MM3 has a cooperative relationship 3 with the target communication cell MM4, and the target communication cell MM5 has a cooperative relationship 4 with the target communication cell MM6; the cooperative relationship 1 and the cooperative relationship 2 have the same target communication cell MM2, and the cooperative relationship 2 and the cooperative relationship 3 have the same target communication cell MM3, and the cooperative relationship 1, the cooperative relationship 2 and the cooperative relationship 3 are selected to combine the target communication cell MM1, the target communication cell MM2, the target communication cell MM3 and the target communication cell MM4 into a cooperative group.
[0056] Step 204: Update the antenna pattern of the target cell according to the coordination group.
[0057] The target communication cell belonging to the coordination group updates the antenna pattern. The manner of adjusting the antenna pattern includes: MR data collection, optimal pattern calculation, KPI evaluation, etc., which will not be described in detail here.
[0058] In one example, the coordination relationship and coordination group are updated periodically; or, after obtaining the update trigger condition, the coordination relationship and coordination group are updated, and the update trigger condition is generated by the member cell in the initial coordination set when a newly added co-frequency neighboring area is detected and the number of handovers of the newly added co-frequency neighboring area is greater than a preset third threshold, and the member cell includes the target communication cell or other communication cells. Other communication cells include: macro cells, etc.
[0059] Specifically, the member cells in the initial collaborative set include the target communication cell or other communication cells. The target communication cell generates the update trigger condition when a newly added co-frequency neighboring cell is detected and the number of switching of the newly added co-frequency neighboring cell is greater than a third threshold. Alternatively, the update trigger condition is generated when other communication cells detect a newly added co-frequency neighboring cell and the number of switching of the newly added co-frequency neighboring cell is greater than a third threshold.
[0060] It should be noted that the target communication cells in the initial coordination set may include: target communication cells of large-scale array antenna type, communication cells of traditional array antenna type. The initial coordination set may also include other communication cells (such as macro type cells).
[0061] Since the large-scale array antenna and the traditional array antenna can adjust the transmission pattern, when establishing a cooperative relationship, the cooperative relationship can be configured according to the configuration sequence listed below.
[0062] 1. Configure a coordinated relationship between a target communication cell of a large-scale array antenna type and a target communication cell of a large-scale array antenna type.
[0063] 2. Configure the coordination relationship between the target communication cell of the large-scale array antenna type and the communication cell of the non-large-scale array antenna type (including the traditional array antenna type and other communication cells).
[0064] 3. Configure a cooperative relationship between a target communication cell of a traditional array antenna type and a target communication cell of a traditional array antenna type.
[0065] 4. Configure the cooperative relationship between the target communication cell of the traditional array antenna type and other communication cells.
[0066] It is understandable that, in order to facilitate configuration of the cooperative relationship, the initial cooperative set can be divided according to whether it includes a large-scale array antenna type, and two types of initial cooperative sets are obtained. For example, the first category includes: target communication cells of large-scale array antenna type, target communication cells of traditional array antenna type and / or other communication cells. The second category includes: target communication cells of traditional array antenna type and other communication cells.
[0067] There are three ways to adjust the antenna pattern: optimizing by adjusting only the communication cells of the massive array antenna type; optimizing by adjusting only the communication cells of the array antenna type; optimizing by adjusting the communication cells of the massive array antenna type and the array antenna type.
[0068] The following describes the collaborative relationship configuration process of the above three optimization methods:
[0069] For ease of description, a target communication cell of a large-scale array antenna type is represented by MM, a target communication cell of an array antenna type is represented by M, and other communication cells are represented by H. The preset time length is set to 24 hours, and the preset time length can be monitored by a timer.
[0070] Optimization method 1: Optimization is performed only by adjusting the target communication cell of the large-scale array antenna type.
[0071] Within the preset time, each MM cell in the initial coordination set performs the following operations:
[0072] Send MR measurement tasks to UEs in the MM cell and collect MR data of the serving cell and the target co-frequency neighboring cell reported by the UE; based on the acquired measurement data, a counter can be used to record the number of times the terminal reports the target co-frequency neighboring cell and the number of times the terminal reports the target communication cell. Among them, all UEs in any MM cell include: UEs in the current MM cell, newly accessed UEs, UEs accessed by neighboring cell handover, and UEs reestablished to the current MM cell.
[0073] When the timer overflows, determine whether the first quantity value of the received service measurement data exceeds the first threshold value. If so, generate the overlapping coverage information between the target communication cell and each target co-frequency neighboring cell according to the first quantity value and the second quantity value of the neighboring cell measurement data; otherwise, continue to send measurement instructions to the UE to continue to receive the MR data of the service cell and the MR data of the target co-frequency neighboring cell reported by the terminal. Calculate the overlapping coverage rate between the target communication cell and at least one target co-frequency neighboring cell, and the calculation process of the overlapping coverage rate will not be repeated here.
[0074] Prioritize configuration of the coordination relationship between the MM cell and its MM neighboring cells: calculate the overlapping coverage between the MM cell and the co-frequency neighboring cells of the MM type; sort the obtained overlapping coverage from large to small to obtain a first sorting result; in the first sorting result, configure the coordination relationship between the MM cell and its MM neighboring cells one by one according to the order from front to back. If the number of MM cells configured with coordination relationships in the initial coordination set is greater than or equal to the preset number b1, stop configuring the coordination relationship between the MM cell and the MM cell, and continue configuring the coordination relationship between the MM cell and its non-MM neighboring cells; wherein the value of b1 is set according to the processing capability of the network device to which the method for configuring the coordination relationship of the communication cells is applied.
[0075] Configure the coordination relationship between the MM cell and its non-MM neighboring cells: calculate the overlapping coverage between the MM cell and the non-MM type (including M type and H type) co-frequency neighboring cells, sort the obtained overlapping coverage from large to small, and obtain the first sorting result; in the first sorting result, configure the coordination relationship between the MM cell and its non-MM neighboring cells one by one according to the order from front to back. If the number of non-MM cells configured with coordination relationships in the initial coordination set is greater than or equal to the preset number b2, stop the coordination relationship configuration between the MM cell and its non-MM neighboring cells. The value of b2 is set according to the processing capability of the current network device.
[0076] If the number of MM cells configured with cooperative relationships in the initial cooperative set is less than the preset number b1, another MM cell is found in the initial cooperative set, and the cooperative relationships between the MM cell and the MM neighboring cell, and between the MM cell and the non-MM neighboring cell are configured according to the above method until all MM cells in the initial cooperative set are traversed or the number of MM cells configured with cooperative relationships in the initial cooperative set is greater than or equal to b1, and the number of non-MM cells configured with cooperative relationships in the initial cooperative set is greater than or equal to b2.
[0077] All cells configured with a coordination relationship in the initial coordination set are grouped into the same coordination group.
[0078] Periodically update the collaboration relationships and collaboration groups.
[0079] If a triggering event is detected, the cooperation relationship and the cooperation group are also updated.
[0080] Optimization method 2: Optimize by adjusting the target communication cell of the large-scale array antenna type.
[0081] Within the preset time, the following operations are performed on each array antenna cell in the initial coordination set:
[0082] Send MR measurement tasks to all UEs in the M cell and collect MR data of the service cell and the target co-frequency neighboring cell reported by the UE. According to the service measurement data obtained, a counter can be used to record the number of times the terminal reports the target co-frequency neighboring cell and the number of times the terminal reports the target communication cell. Among them, all UEs in the M cell include: UEs in the current M cell, newly accessed UEs, UEs accessed by neighboring cell handover, and UEs reestablished to the current M cell.
[0083] When the timer overflows, determine whether the number of received service measurement data exceeds the first threshold value. If so, generate overlapping coverage information between the target communication cell and each target co-frequency neighboring cell according to the first number value and the second number value of the neighboring cell measurement data; otherwise, continue to send measurement instructions to the UE to continue to receive service measurement data reported by the terminal.

[0088] Periodically update the collaboration relationships and collaboration groups.
[0089] If a triggering event is detected, the cooperation relationship and the cooperation group are also updated.
[0090] Optimization method three: Optimize by adjusting the large-scale array antenna type and the target communication cell of the array antenna type.
[0091] Within the preset time, the following operations are performed on each large-scale array antenna cell and array antenna cell in the initial coordination set:
[0092] At the same time, MR measurement tasks are sent to UEs in the MM cell and the M cell, and MR data of the service cell and the target co-frequency neighboring cell reported by the UE are collected; the measurement data includes the MR data of the service cell of the UE and the MR data of the co-frequency neighboring cell. According to the acquired measurement data, a counter can be used to record the number of times the terminal reports the co-frequency neighboring cell and the number of times the terminal reports the target communication cell. Among them, all UEs in the MM cell or M cell include: UEs in the current MM cell or M cell, newly accessed UEs, UEs accessed by neighboring cell handover, and UEs re-established in the current MM cell or M cell.
[0093] When the timer overflows, determine whether the amount of measurement data received by the MM cell or the M cell exceeds the first threshold. If so, generate overlapping coverage information between the MM cell or the M cell and each co-frequency neighboring cell based on the service measurement data and the neighboring cell measurement data; otherwise, continue to send measurement instructions to the UE to continue to receive the measurement data reported by the terminal.
[0094] The overlapping coverage between the MM cell or the M cell and at least one target co-frequency neighboring cell is calculated.
[0095] First, configure the coordination relationship between the MM cell and the MM neighboring cells: give priority to calculating the overlapping coverage between the MM cell and the MM type co-frequency neighboring cells; sort the obtained overlapping coverage from large to small to obtain the first sorting result; in the first sorting result, configure the coordination relationship between the MM cell and its MM neighboring cells one by one according to the order from front to back. If the number of MM cells configured with coordination relationships in the initial coordination set is greater than or equal to the preset number b1, stop the coordination relationship configuration between the MM cell and the MM cell, and continue the coordination relationship configuration between the MM cell and the non-MM neighboring cells; the value of b1 is set according to the processing capability of the current network equipment.
[0096] Secondly, configure the coordination relationship between the MM cell and the non-MM neighboring cells: calculate the overlapping coverage between the MM cell and the non-MM type co-frequency neighboring cells, sort the obtained overlapping coverage from large to small, and obtain the first sorting result; in the first sorting result, configure the coordination relationship between the MM cell and its non-MM neighboring cells one by one according to the order from front to back. If the number of non-MM cells configured with coordination relationships in the initial coordination set is greater than or equal to the preset number b2, stop the coordination relationship configuration between the MM cell and its non-MM cells. The value of b2 is set according to the processing capability of the current network device.
[0097] If the number of MM cells configured with cooperative relationships in the initial cooperative set is less than the preset number b1, another MM cell is found in the initial cooperative set, and the cooperative relationships between the MM cell and the MM neighboring cell, and between the MM cell and the non-MM neighboring cell are configured according to the above method until all MM cells in the initial cooperative set are traversed or the number of MM cells configured with cooperative relationships in the initial cooperative set is greater than or equal to b1, and the number of non-MM cells configured with cooperative relationships in the initial cooperative set is greater than or equal to b2.
[0098] Next, if the number of MM cells configured with a cooperative relationship in the initial cooperative set is still less than the preset number b1, the cooperative relationship between the M cells and the M cells is configured: the overlapping coverage between the M cell and the co-frequency neighboring cells belonging to the M type is preferentially calculated; the obtained overlapping coverage is sorted from large to small to obtain a first sorting result; in the first sorting result, the cooperative relationship between the M cell and its M neighboring cells is configured one by one according to the order from front to back. If the total number of MM cells and M cells configured with a cooperative relationship in the initial cooperative set is greater than or equal to the preset number b1, the configuration of the cooperative relationship between the M cells and the M cells is stopped, and the configuration of the cooperative relationship between the M cell and other types of neighboring cells is continued.
[0099] Finally, if the total number of other types of cells configured with a coordinated relationship in the initial coordinated set is less than the preset number b2, the coordinated relationship between the M cell and other types of cells is configured: the overlapping coverage between the M cell and other types of co-frequency neighboring cells is calculated, and the obtained overlapping coverage is sorted from large to small to obtain a first sorting result; in the first sorting result, the coordinated relationship between the M cell and other types of neighboring cells is configured one by one according to the order from front to back. If the total number of other types of cells configured with a coordinated relationship in the initial coordinated set is greater than or equal to the preset number b2, the configuration of the coordinated relationship between the M cell and other types of neighboring cells is stopped.
[0100] If the total number of MM cells and M cells configured with collaborative relationships in the initial collaborative set is still less than the preset number b1, another M cell is found in the initial collaborative set, and the collaborative relationships between the M cell and the M neighboring cells, and between the M cell and other types of neighboring cells are configured according to the above method until all M cells in the initial collaborative set are traversed or the total number of MM cells and M cells configured with collaborative relationships in the initial collaborative set is greater than or equal to b1, and the number of other types of cells configured with collaborative relationships in the initial collaborative set is greater than or equal to b2.
[0101] All cells configured with a coordination relationship in the initial coordination set are grouped into the same coordination group.
[0102] The collaborative relationship and the collaborative group are updated periodically. If a trigger event is detected, the collaborative relationship and the collaborative group are also updated.
[0103] The third embodiment of the present invention relates to a method for configuring a coordinated relationship of communication cells. This embodiment is substantially the same as the second embodiment, with the main difference being that in this embodiment, an associated cell is obtained by the number of same-frequency handovers. The specific implementation of selecting an associated cell associated with a target communication cell in this embodiment is as follows: Figure 4 As shown:
[0104] Step S31: Obtain the number of intra-frequency handovers between the target communication cell and at least one target intra-frequency neighboring cell, where the target intra-frequency neighboring cell is the intra-frequency neighboring cell of the target communication cell.
[0105] Obtain the number of intra-frequency handovers between the target communication cell and at least one target intra-frequency neighboring cell.
[0106] Specifically, the target communication cell may have one or more target co-frequency neighboring cells, and the number of co-frequency handovers between the target communication cell and at least one target co-frequency neighboring cell is obtained.
[0107] Step S32: Select a target intra-frequency neighboring cell corresponding to the intra-frequency switching number that meets the second selection condition.
[0108] The second selection condition is that the number of intra-frequency handovers is greater than the preset sixth threshold. The sixth threshold is recorded as MinHOCntThre. The number of intra-frequency handovers between the target communication cell and all its intra-frequency neighboring cells is compared with the sixth threshold, and the target intra-frequency neighboring cell corresponding to the number of intra-frequency handovers greater than the sixth threshold is selected. The sixth threshold can be set according to the actual application, and by comparing with the sixth threshold, the intra-frequency handovers with a small number of times can be quickly screened out.
[0109] Step S33: Obtain associated cells according to the selected target co-frequency neighboring cells.
[0110] The number of co-frequency handovers corresponding to the at least two selected target co-frequency neighboring cells is sorted to obtain a second sorting result. According to the second sorting result and a preset number, an associated cell is obtained; wherein the preset number is set according to the processing capability of the network device. If the number of selected target co-frequency neighboring cells is 1, no sorting is required, and the associated cell is directly obtained according to the preset number.
[0111] Specifically, a sorting method from small to large or from large to small can be used; in this embodiment, the number of co-frequency switching times corresponding to at least two target co-frequency neighboring cells is sorted from large to small to obtain a second sorting result. The following processing is performed in the order of the sorting results: the target co-frequency neighboring cell is used as an associated cell of the target communication cell, and a cooperative relationship between the target communication cell and the associated cell is configured, and it is detected whether the total number of all target communication cells configured with cooperative relationships in the initial cooperative set is less than the preset number b1. If so, the next target co-frequency neighboring cell of the type of the target communication cell is used as an associated cell of the current target communication cell and a cooperative relationship between the two is configured; the total number of all communication cells configured with cooperative relationships in the initial cooperative set is detected whether it is less than the preset number b2. If so, the next target co-frequency neighboring cell of the type of other communication cells in the first sorting result is used as an associated cell of the target communication cell and a cooperative relationship between the two is configured. This continues until all target co-frequency neighboring cells of the selected target communication cell are selected as associated cells of the target communication cell and a collaborative relationship is configured with the target communication cell; or, until the total number of all target communication cells configured with a collaborative relationship in the initial collaborative set is greater than or equal to the preset number b1, and the total number of all communication cells configured with a collaborative relationship is greater than or equal to the preset number b2.
[0112] If after all selected target co-frequency neighboring cells are selected as associated cells and configured with a collaborative relationship, it is detected that the total number of all target communication cells configured with a collaborative relationship in the initial collaborative set is less than the preset number b1, continue to execute steps S41 to S43 for the next target communication cell until all target communication cells in the initial collaborative set are traversed; or, until the total number of all current target communication cells configured with a collaborative relationship in the initial collaborative set is greater than or equal to the preset number b1 and the total number of communication cells configured with a collaborative relationship is greater than or equal to the preset number b2.
[0113] It should be noted that when the number of target communication cells and associated cells configured with a coordinated relationship is greater than the preset number of communication cells processed by the network device, the processing of target communication cells in the initial coordinated set that are not configured with a coordinated relationship is stopped.
[0114] It is worth mentioning that the method for configuring the communication cell coordination relationship in the embodiment can quickly obtain the associated cells, thereby improving the speed of obtaining the associated cells, thereby improving the speed of configuring the coordination relationship between the target communication cell and the associated cells; and improving the speed of configuring the coordination group.
[0115] It is understandable that after the updating of the coordination relationship is triggered, the associated cells may be updated in the manner of acquiring associated cells in the second embodiment, thereby reconfiguring the coordination relationship and the coordination group.
[0116] A fourth embodiment of the present invention relates to a method for configuring a cooperative relationship between communication cells. The method can be applied to a network device for managing each communication cell. The process is as follows: Figure 5 Shown include:
[0117] Step 401: According to a specified type, a measurement group matching the specified type is obtained, where the measurement group includes at least one of the target communication cells.
[0118] Step 402: Traverse the co-frequency neighboring cells of each target communication cell in the search measurement group, and update the measurement group according to the searched co-frequency neighboring cells until a preset condition is met; the preset condition includes: the types of the searched co-frequency neighboring cells are not the specified type, or the number of target communication cells of the specified type in the measurement group exceeds the preset fourth threshold, or the number of communication cells in the measurement group exceeds the preset fifth threshold.
[0119] Step 403: The updated measurement group is used as an initial coordination set, so that the target communication cell can obtain associated associated cells from the initial coordination set; the target communication cell configures a coordination relationship with the associated cells.
[0120] In an embodiment of the present invention, a measurement group matching a specified type is obtained, and the co-frequency neighboring areas of each target communication cell in the search measurement group are traversed, and the measurement group is updated according to the searched co-frequency neighboring areas until a preset condition is met. Since the initial collaborative set is not manually specified, the acquisition speed of the initial collaborative set is effectively improved; at the same time, the measurement group is updated according to the co-frequency neighboring areas of the target communication cell to obtain the initial collaborative set, which increases the number of communication cells associated with the target communication cell in the initial collaborative set, so that subsequent target communication cells can quickly obtain associated cells associated with the target communication cell.
[0121] The fifth embodiment of the present invention relates to a method for configuring a cooperative relationship of communication cells. This embodiment is a detailed introduction to steps 401 to 403 of the fourth embodiment, and the specific implementation is as follows:
[0122] Step 401: According to a specified type, a measurement group matching the specified type is obtained, where the measurement group includes at least one target communication cell.
[0123] Specifically, the specified type includes: large-scale array antenna type or traditional array antenna type. The specified type can be pre-set, and the process of obtaining a measurement group matching the specified type can be: in the target area, any specified type of target communication cell can be selected as the central cell, and the matching target co-frequency neighboring cell of the central cell is searched, and the matching target co-frequency neighboring cell and the specified type of target communication cell are used as the measurement group. The following is a specific example to introduce the process of obtaining the measurement group under two specified types:
[0124] If the specified type is a large-scale array antenna type, the communication cell belonging to the large-scale array antenna type in the target area can be selected as the central cell based on the KPI and other data in the target area, and the same-frequency neighboring cell matching the large-scale array antenna type is searched. The same-frequency neighboring cell matching the large-scale array antenna type means: the cell type can be a large-scale array antenna type, a traditional array antenna or other types.
[0125] If the specified type is a traditional array antenna, the communication cell of the traditional array antenna type in the target area can be selected as the central cell based on the KPI and other data in the target area, and the same-frequency neighboring cell matching the traditional array antenna type is searched. The same-frequency neighboring cell matching the traditional array antenna type means: the cell type is a traditional array antenna or other types, but there is no large-scale array antenna type.
[0126] Step 402: traverse the search for the same-frequency neighboring cells of each target communication cell in the measurement group, and update the measurement group according to the searched same-frequency neighboring cells until the preset conditions are met.
[0127] In one example, the preset conditions include: the types of the searched co-frequency neighboring cells are not of the specified type, or the number of communication cells of the specified type in the measurement group exceeds a preset fourth threshold, or the number of communication cells in the measurement group exceeds a preset fifth threshold.
[0128] Specifically, in order to facilitate the configuration of the coordination relationship, the initial coordination set can be divided according to whether it contains a large-scale antenna type, and two types of initial coordination sets are obtained. There are three ways to adjust the antenna pattern, namely: optimize by adjusting the target communication cell of the large-scale array antenna type only; optimize by adjusting the target communication cell of the array antenna type only; optimize by adjusting the target communication cell of the large-scale array antenna type and the array antenna type.
[0129] The measurement group can be updated according to three optimization types and two specified types. Figure 6Introduce the update process. For the convenience of description, the communication cells of large-scale array antenna type are represented by MM, the communication cells of array antenna type are represented by M, and other communication cells are represented by H. Figure 6 Schematic diagram of a target communication cell within a target area.
[0130] Optimization method 1: Optimization is performed only by adjusting the target communication cell of the large-scale array antenna type; the specified type in this optimization method is a large-scale array antenna.
[0131] The update process is: Figure 6 As shown, any target communication cell of a specified type is designated as the initial measurement group. For example, the target communication cell designated in this example is: MM 1.
[0132] Step 1-1: First search for MM1's co-frequency handover neighboring cells and obtain Figure 6 MM2, MM4 and M1~M6 in the measurement group are added to them. The same-frequency neighboring cells of the same-frequency switching neighboring cells of MM1 in the current measurement group, which belong to the Massive MIMO type, are preferentially used as the search center for the search, such as MM2 and MM4; MM2 can be used as the search center first to search for the same-frequency neighboring cells that match the large-scale array antenna type. The search types include large-scale array antenna type, traditional array antenna type and other types, such as Figure 6 The co-frequency neighboring cells of MM2 found in the search include MM1, MM3, M4~9; then with MM4 as the search center, the co-frequency neighboring cells of MM4 are found to include MM1, M1, M5, and M12, and the same items are merged, and the duplicate communication cells are deleted, and the measurement group is updated, that is, the newly added co-frequency neighboring cells, such as MM3, M7~M9, and M12 are added to the measurement group to obtain the updated measurement group. It should be noted that if the co-frequency neighboring cells of all MM cells in the measurement group have been searched, and there are no MM cells in the newly added co-frequency neighboring cells; you can continue to perform steps 1-2.
[0133] Step 1-2: Continue to traverse the macro-type communication cells in the same-frequency neighboring cells of MM1 one by one, such as M1 to M6. Similar to step 1-1, search for the same-frequency neighboring cells of M1, and determine whether there are new MM cells in the searched same-frequency neighboring cells. If so, merge the MM cells with the same type and add them to the measurement group; if there are no new MM cells, continue to search for the next macro-type cell;
[0134] Whenever a new MM cell is added to the measurement group, steps 1-1 and 1-2 are repeated. For example, if the new MM cell is MM3, the new MM cell (such as Figure 6With MM3 in the measurement group as the center, check the co-frequency neighboring cells of the newly added MM cells in the measurement group according to steps 1-1 and 1-2, merge the newly added neighboring cells with the same type (such as M10 and M11) and add them to the measurement group until no new MM cells are added to the measurement group or the total number of MM cells in the measurement group reaches the upper limit of the device processing, or the total number of cells reaches the upper limit of the device processing.
[0135] Optimization method 2: Optimization is performed only by adjusting the communication cell of the array antenna type; the specified type in this optimization method is the traditional array antenna type.
[0136] The updating process is: specify any target communication cell of array antenna type as the measurement group. For example, the target communication cells included in the measurement group in this example are: M1 cell. The updating process is similar to the first optimization method.
[0137] Step 2-1: First search for the co-frequency neighboring cells of M1, and add the searched co-frequency neighboring cells to the measurement group. Then, use the traditional array antenna type cells other than M1 in the current measurement group as the search center, search for the co-frequency neighboring cells of the specified type of the search center, and the types of communication cells searched include: traditional array antenna type and other communication cells (such as macro cells), and add the searched co-frequency neighboring cells to the measurement group. If the co-frequency neighboring cells of all M type cells in the measurement group have been traversed, and there are no M type cells in the newly added co-frequency neighboring cells, you can continue to execute step 2-2.
[0138] Step 2-2: Continue to search for the same-frequency handover neighboring cells of other types of cells in the measurement group one by one, and determine whether there is a newly added M-type cell among the searched same-frequency neighboring cells. If so, merge the M-type cells with the same type and add them to the measurement group; if there is no newly added M-type cell, do not update the measurement group;
[0139] Whenever a new M cell is added to the measurement group, steps 2-1 and 2-2 are repeated to check the co-frequency neighboring cells of the newly added M cell in the measurement group, merge the newly added neighboring cells with the same type and add them to the measurement group until there are no new M cells in the measurement group or the total number of M cells in the measurement group reaches the processing upper limit of the network device, or the total number of cells reaches the processing upper limit of the network device.
[0140] Optimization method 3: Optimization is performed by adjusting the target communication cells of the large-scale array antenna type and the traditional array antenna type. The specified type in this optimization method is the large-scale array antenna type.
[0141] The updating process is: specifying any target communication cell of the large-scale array antenna as the initial measurement group. For example, the target communication cell specified in this example is: MM 1.
[0142] Step 3-1: First search for MM1's co-frequency handover neighboring cells, obtain MM2, MM4, and M1 to M6, and add them to the measurement group. The co-frequency neighboring cells of the Massive MIMO type in the co-frequency handover neighboring cells of MM1 in the current measurement group are used as the search center, such as MM2 and MM4; MM2 can be used as the search center to search for co-frequency neighboring cells that match the Massive MIMO type. The search types include Massive MIMO type, traditional array antenna type, and other types, such as Figure 6 The co-frequency neighboring cells of MM2 found in the search include MM1, MM3, M4~9; then with MM4 as the search center, the co-frequency neighboring cells of MM4 are found to include MM1, M1, M5, and M12, and the same items are merged, and the duplicate communication cells are deleted, and the measurement group is updated, that is, the newly added co-frequency neighboring cells, such as MM3, M7~M9, and M12 are added to the measurement group to obtain a new measurement group. It should be noted that if the co-frequency neighboring cells of all MM cells in the measurement group have been searched, and there are no MM cells in the newly added co-frequency neighboring cells; you can continue to perform step 3-2.
[0143] Step 3-2: Continue to use the target communication cells of the traditional array antenna type in the measurement group as the search center one by one, such as M1 to M6. Similar to step 1-1, use M1 as the search center to search for M1's co-frequency neighboring cells, such as Figure 7 The dotted circle shown in , after merging the same frequency neighboring cells of the M1 cell with the same items, also adds the measurement group;
[0144] Step 3-3: Use the traditional array antenna cells other than M1 in the current measurement group as the search center one by one, and search for the same-frequency neighboring cells of the specified type of the search center, such as Figure 7 The dotted circle with M9 as the search center is shown in the figure. Figure 7 Only the dotted circles with M1 and M9 as the search center are shown, and the types of communication cells searched include: large-scale array antenna type, traditional array antenna type and other communication cells (such as macro cells, Figure 7 If the co-frequency neighboring cells of all M cells in the measurement group have been traversed, and there are no M cells and MM cells in the newly added co-frequency neighboring cells, then step 3-4 can be continued; if an MM cell appears in the newly added co-frequency neighboring cells, step 3-1 is repeated.
[0145] Step 3-4: Continue to search for the same-frequency handover neighboring cells of other types of cells in the measurement group one by one, and determine whether there are newly added M cells and MM cells in the searched same-frequency neighboring cells. If so, merge the M cells and MM cells into the same category and add them to the measurement group; if there are no newly added M cells and MM cells, do not update the measurement group;
[0146] Whenever a new MM cell is added to the measurement group, step 3-1 is repeatedly executed; whenever a new M cell is added to the measurement group, step 3-2 is repeatedly executed; until the neighboring cells of all cells in the measurement group are traversed and the newly added co-frequency neighboring cells no longer contain MM cells and traditional array antenna cells, or the number of MM cells or traditional array antenna cells in the measurement group reaches the processing upper limit of the device, or the number of all communication cells in the measurement group reaches the processing upper limit of the device, the operation of searching for co-frequency neighboring cells is terminated and the measurement group is stopped from being updated.
[0147] Step 403: The updated measurement group is used as an initial coordination set, so that the target communication cell can obtain the associated associated cells, the coordination relationship between the target communication cell configuration and the associated cells from the initial coordination set.
[0148] In this embodiment, the network device automatically searches for the same-frequency neighboring area that matches the specified type and automatically generates a measurement group, eliminating the need to manually divide the measurement group, thereby improving the efficiency of obtaining the measurement group. In addition, obtaining the measurement group according to the specified type also facilitates the subsequent configuration of the collaborative relationship for the communication cells in the measurement group.
