Description

Interference coordination method, device and storage medium

Technical Field

The present application relates to the field of communications, and in particular, to an interference coordination method, apparatus, and storage medium.

Background

With the development of mobile communication networks, spectrum resources are becoming more and more scarce. In order to improve the utilization rate of the frequency spectrum resources, the frequency spectrum resources need to be shared among different network systems. However, when cells of different network systems use the same spectrum resource for data transmission, the problem of signal interference between cells is likely to occur.

In the related art, the spectrum resources of the cells with signal interference are scheduled, so that the spectrum resources used among the cells are not overlapped in a frequency domain, thereby avoiding the signal interference.

The interference coordination apparatus 101 is configured to acquire a first interfering cell causing interference to a target cell.

The target cell is any cell 104 in a preset area, and the first interfering cell is a cell causing interference to the target cell.

In a possible implementation manner, the interference coordination apparatus 101 sends an interference detection message to the target cell, and accordingly, the target cell receives the interference detection message sent by the interference coordination apparatus 101.

The target cell is configured to determine a first interference cell and send an interference response message to the interference coordination apparatus 101, and correspondingly, the interference coordination apparatus 101 receives the interference response message sent by the target cell.

Wherein the interference response message includes a cell identity of the first interfering cell.

It should be noted that, since the access network device 102 may configure one or more cells 104, in order to distinguish different cells in the preset area, in the present application, communication between the interference coordination apparatus 101 and the access network device 102 where the cell 104 in the preset area is located is expressed as communication between the interference coordination apparatus 101 and the cell 104.

The interference coordination apparatus 101 is further configured to obtain a compensation cell corresponding to each first interfering cell.

And the compensation cell and the corresponding first interference cell have overlapped wireless signal coverage areas. One first interfering cell may correspond to one or more compensating cells.

It should be noted that, because there is an overlapping wireless signal coverage area between the compensating cell and the corresponding first interfering cell, the UE103 in the first interfering cell is less affected by network communication after being switched from the first interfering cell to the corresponding compensating cell.

The interference coordination device 101 is further configured to determine a second interfering cell from the first interfering cell.

And the second interference cell is a cell to be subjected to interference coordination in the first interference cell.

The interference coordination apparatus 101 is further configured to instruct one or more UEs in the second interfering cell to switch to a compensating cell corresponding to the second interfering cell.

In a possible implementation manner, the interference coordination apparatus 101 sends a migration trigger message to each second interfering cell, and correspondingly, the second interfering cell receives the migration trigger message sent by the interference coordination apparatus 101.

The second interfering cell is used for switching one or more UEs in the second interfering cell to a corresponding compensating cell in response to the migration trigger message.

The interference coordination apparatus 101 is further configured to instruct the second interfering cell to perform an interference coordination operation.

In a possible implementation manner, the interference coordination apparatus 101 sends an interference coordination message to each second interfering cell, and correspondingly, the second interfering cell receives the interference coordination message sent by the interference coordination apparatus 101.

The second interfering cell is configured to perform an interference coordination operation in response to the interference coordination message.

Illustratively, the second interfering cell stops data transmission on the corresponding interfering sub-band. The interference sub-band is a sub-band where the second interfering cell causes interference to the target cell.

In the present application, before instructing the second disturbing cell to perform the interference coordination operation, the interference coordination apparatus 101 instructs one or more UEs in the second disturbing cell to switch to the compensation cell corresponding to the second disturbing cell, so as to avoid a problem that the UE accessing the second disturbing cell cannot perform normal data transmission during the interference coordination process of the second disturbing cell, thereby ensuring service requirements of users.

It should be noted that the various embodiments of the present application may be referred to or referred to one another, for example, the same or similar steps, method embodiments, system embodiments, and apparatus embodiments may be referred to one another, without limitation.

Fig. 2 is a flowchart of an interference coordination method according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:

step 201, the interference coordination apparatus acquires a first interfering cell causing interference to the target cell.

The target cell is any cell in a preset area, and the first disturbing cell is a cell causing interference to the target cell. The range of the preset area may be set according to actual conditions, which is not limited in this application.

In one possible implementation, the interference coordination apparatus sends an interference detection message to the target cell, and correspondingly, the target cell receives the interference detection message sent by the interference coordination apparatus.

The target cell determines a first interference applying cell and sends an interference response message to the interference coordination device, and correspondingly, the interference coordination device receives the interference response message sent by the target cell.

For example, the target cell may determine the first interfering cell causing interference according to the interference experienced by each sub-band in the operating band.

Step 202, the interference coordination apparatus obtains a compensation cell corresponding to each first interfering cell.

In a possible implementation manner, for each first interfering cell, the interference coordination apparatus may determine, according to a measurement report of UE in the first interfering cell, a candidate compensating cell corresponding to the first interfering cell, and determine, according to a measurement report of UE in the candidate compensating cell, a compensating cell corresponding to the first interfering cell.

The measurement report includes the signal strength of the accessed cell measured by the UE and the signal strength of the neighboring cell in the preset area.

For example, the signal strength may be the signal strength of an existing reference signal (reference signal), such as a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), or the like, or may be the signal strength of a reference signal newly introduced in the future.

Step 203, the interference coordination device determines a second interference cell from the first interference cell.

In a possible implementation manner, the interference coordination apparatus uses a cell satisfying a first preset condition in the first interfering cell as the second interfering cell.

Wherein the first preset condition comprises at least one of the following: the compensation network system set comprises each network system supported by the first target UE, the compensation working frequency band set comprises each working frequency band supported by the first target UE, and the compensation available capacity is larger than or equal to the traffic of the first interference cell.

It should be noted that, the first target UE is a UE in the first interfering cell, the compensation network format set includes a network format supported by each corresponding compensation cell, the compensation operating frequency band set includes an operating frequency band supported by each corresponding compensation cell, and the compensation available capacity is a sum of available capacities of each corresponding compensation cell.

The available capacity of the compensating cell may be a difference between a maximum traffic supported by the compensating cell and an average traffic of the compensating cell in a preset period.

The interference coordination device determines a second interference cell to be subjected to interference coordination from the first interference cell based on information such as network configuration and service volume supported by the UE in the first interference cell and the corresponding compensation cell, so that one or more UEs in the second interference cell are smoothly migrated to the corresponding compensation cell in the subsequent interference coordination re-execution process, and service requirements of each UE in the second interference cell are met.

Illustratively, the first interfering cell includes UE1 and UE2, where the network standard supported by UE1 includes {3G, 4G }, and the supported operating frequency band includes { band1, band3 }. The network standard supported by the UE2 includes {4G }, and the supported working frequency band includes { band2 }. The compensation cell corresponding to the first disturbing cell comprises a cell 1 and a cell 2. The network standard supported by the cell 1 includes {3G }, and the working frequency band supported by the cell 1 includes { band1 }. The network standard supported by the cell 2 includes {4G }, and the working frequency band supported by the cell 2 includes { band3 }. The compensation network system set comprises 3G, 4G, and the compensation working frequency band set comprises band1, band 3. Therefore, the compensated network format set includes each network format supported by the UE1 and the UE2, and the compensated operating frequency band set includes each operating frequency band supported by the UE1 and does not include the operating frequency band supported by the UE 2.

In a possible implementation manner, before step 203, the interference coordination apparatus may further determine, for each target interfering cell, first capability information of the target interfering cell, and determine, for each target compensating cell, second capability information of the target compensating cell.

The target disturbance cell is any one of the first disturbance cells, the target compensation cell is any one of the compensation cells corresponding to the target disturbance cell, and the first capability information comprises a network system and a working frequency band supported by each UE in the target disturbance cell and the traffic of the target disturbance cell; the second capability information comprises a compensation network system set, a compensation working frequency band set and a compensation available capacity.

For example, the interference coordination apparatus may send a first capability request message to the target interfering cell, and the interference coordination apparatus receives a first capability response message sent by the target interfering cell.

The first capability request message is used for indicating a target interference cell to acquire first capability information; the first capability response message includes first capability information of the target offending cell.

The interference coordination device may send a second capability request message to the target compensation cell, and the interference coordination device receives a second capability response message sent by the target compensation cell.

The second capability request message is used for indicating the target compensation cell to acquire second capability information; the second capability response message includes second capability information of the target compensating cell.

Step 204, the interference coordination apparatus instructs one or more UEs in the second interfering cell to switch to a compensating cell corresponding to the second interfering cell.

In a possible implementation manner, the interference coordination apparatus sends a migration trigger message to each second interfering cell, and correspondingly, the second interfering cell receives the migration trigger message sent by the interference coordination apparatus and instructs one or more UEs in the second interfering cells to switch to the corresponding compensating cells.

The migration trigger message may include an interference sub-band of the second interfering cell, a cell identifier of a compensating cell corresponding to the second interfering cell, and a network standard, a working frequency band, and an available capacity supported by the compensating cell.

It should be noted that each UE may determine the compensation cell to be migrated according to the measured signal strengths of the plurality of compensation cells, so that the UE may still maintain good data transmission quality after migration.

Step 205, the interference coordination apparatus instructs the second interfering cell to perform interference coordination operation.

In one possible implementation, the interference coordination apparatus sends an interference coordination message to each second interfering cell. Correspondingly, the second interference cell receives the interference coordination message sent by the interference coordination device. The second interfering cell stops data transmission on the corresponding interfering sub-band in response to the interference coordination message.

The interference coordination message is used for instructing the second interfering cell to stop data transmission on the corresponding interference sub-frequency band. The interference coordination message may include an interference sub-band of the second interfering cell and a network standard supported by the target cell.

In a possible implementation manner, when the interference sub-band of the second interfering cell is a part of the sub-band in the operating band of the second interfering cell, the second interfering cell may set the interference sub-band as the silence band. I.e. the second interfering cell stops data transmission on the interfering sub-band.

When the interference sub-band of the second interfering cell is all the sub-bands in the working band of the second interfering cell, the second interfering cell may set the working band to the silent band. That is, the second disturbing cell is configured to be in a closed state, and the data transmission of the second disturbing cell is stopped.

Optionally, when the access network device where the second disturbing cell is located is configured with other cells of the same type as the network type supported by the target cell, the access network device may allocate the spectrum resource of the second disturbing cell to the cells of the same type. By distributing the frequency spectrum resource of the second interference cell to other cells of the same system, the technical scheme of the application can further improve the utilization rate of the frequency spectrum resource while reducing the signal interference of the target cell.

Based on the technical scheme, the interference coordination device in the application determines a second interference cell to be subjected to interference coordination from the first interference cell by acquiring the first interference cell causing interference to the target cell in the preset region and the compensation cell corresponding to the first interference cell. Before instructing the second interfering cell to perform the interference coordination operation, the interference coordination apparatus may first instruct one or more UEs in the second interfering cell to switch to a compensation cell corresponding to the second interfering cell. Therefore, in the interference coordination execution process, the technical scheme of the application can not only avoid the target cell from being interfered by signals, improve the network performance of the target cell, but also prevent the accessed UE from being incapable of normally performing data transmission due to the reduction of available frequency spectrum resources when the second interference cell executes the interference coordination operation, thereby ensuring the service requirements of users.

In the following, a procedure for determining a target cell in a preset area by an interference coordination apparatus is described.

As a possible embodiment of the present application, in conjunction with fig. 2, as shown in fig. 3, before step 201 described above, the method further includes the following steps 301 to 303.

Step 301, the interference coordination apparatus obtains configuration information of each cell in a preset area.

The configuration information includes at least one of a cell identifier, a currently configured working frequency band of the cell, and a network system supported by the cell.

In one possible implementation, the interference coordination apparatus sends a configuration request message to each cell in the preset area. Correspondingly, the cell in the preset area receives the configuration request message sent by the interference coordination device.

The cell in the preset area sends a configuration response message to the interference coordination device, and correspondingly, the interference coordination device receives the configuration response message sent by the cell in the preset area.

The configuration request message is used for acquiring configuration information of the cell, and the configuration response message includes the configuration information of the cell.

Step 302, the interference coordination apparatus takes a cell satisfying a second preset condition in each cell in the preset area as a preset cell.

Wherein the second preset condition comprises: and overlapping frequency bands exist between the currently configured working frequency band and the preset frequency band of the cell. The preset frequency band is a frequency band shared among cells in a preset area. Each cell in the preset area can transmit data through the preset frequency band.

It should be noted that, the frequency band where the currently configured operating frequency band of the cell overlaps with the preset frequency band means that the same sub-frequency band exists in the currently configured operating frequency band of the cell and the preset frequency band. The predetermined frequency band may be divided into a plurality of sub-frequency bands, each having the same bandwidth.

Illustratively, the currently configured operating frequency band of the cell is 949-. The currently configured working frequency band of the cell and the preset frequency band have the same sub-frequency band, that is, a plurality of sub-frequency bands included in the 949 + 960MHz frequency band, taking 5G as an example, if the bandwidth of each sub-frequency band is 1 PRB, the 949 + 960MHz frequency band includes 51 PRB corresponding to 51 sub-frequency bands. The cell thus satisfies a second predetermined condition. Based on the above technical solution, the interference coordination apparatus may determine a potentially interfered cell from a preset area.

Step 303, the interference coordination apparatus determines the target cell according to the network type supported by the preset cell.

In a possible implementation manner, the interference coordination apparatus determines a priority corresponding to the preset cell according to a network type supported by the preset cell, and determines the target cell according to the priority corresponding to the preset cell.

The priority corresponding to the preset cell is used for reflecting the importance degree of the network system supported by the preset cell. Different network systems correspond to different priorities. The priority corresponding to each network type can be configured in the interference coordination device in advance. For example, the priority may be configured as: the priority of 5G is higher than that of 4G, and the priority of 4G is higher than that of 3G. The corresponding relationship between the network system and the priority may be set according to actual conditions, which is not limited in this application.

As a possible embodiment, in response to that the preset cell includes a cell with the highest priority, the interference coordination apparatus determines that the target cell is the cell with the highest priority.

And responding to the preset cells comprising a plurality of cells with the highest priority, the interference coordination device acquires the service parameters of the cells with the highest priority, and determines the target cell according to the service parameters of the cells with the highest priority.

The service parameter includes at least one of a cell traffic factor and a cell performance factor in a preset period, where the cell traffic factor is used to represent the size of the traffic carried by the cell, and the cell performance factor is used to represent the importance degree of the service carried by the cell.

For example, the traffic factor may be a ratio of the traffic of the cell to the sum of the traffic of the cells in the predetermined cell. The traffic volume of a cell may be determined according to one or more parameters of the throughput rate, the number of connected users, and the resource utilization rate of a Physical Resource Block (PRB) of the cell. The performance factor may be a ratio of the number of high performance service connections established in a cell to the number of all service connections established in the cell. High performance services may be determined based on quality of service (QoS) parameters.

In a possible implementation manner, the interference coordination apparatus performs weighted summation on the traffic factor and the performance factor of each of the cells with the highest priority to obtain a plurality of weights, and takes the cell corresponding to the highest weight in the plurality of weights as the target cell.

Wherein, the plurality of cells with the highest priority are in one-to-one correspondence with the plurality of weights.

It should be noted that the sum of the weights of the traffic factor and the performance factor is 1, and the weight value may be specifically set according to an actual situation, which is not limited in this application.

In a possible implementation manner, the interference coordination apparatus sends the service parameter request message to each of the cells with the highest priority, and the cell with the highest priority receives the service parameter request message sent by the interference coordination apparatus.

The cell with the highest priority sends a service parameter response message to the interference coordination device, and correspondingly, the interference coordination device receives the service parameter response messages sent by the cells with the highest priority.

The service parameter request message is used for acquiring service parameters of the cell; the service parameter response message includes the service parameters of the cell.

Based on the technical scheme, the interference coordination device in the application determines a potential interfered cell according to configuration information by acquiring the configuration information of each cell in a preset area, and further determines a target cell according to multiple dimensions such as the priority, the traffic and the service performance requirement of the cell, so that interference coordination is performed on the cell in the following process, and the cell is prevented from being interfered by signals. Therefore, the method and the device can preferentially ensure the signal quality of the cell with higher priority level, larger service volume and higher service performance requirement, thereby improving the overall service performance of the cell in the preset area.

In the following, a procedure for an interference coordination apparatus to acquire a first interfering cell causing interference to a target cell is described.

As a possible embodiment of the present application, in conjunction with fig. 2, as shown in fig. 4, the step 201 described above can also be implemented by the following steps 401 to 403.

Step 401, the interference coordination apparatus sends an interference detection message to the target cell. Correspondingly, the target cell receives the interference detection message sent by the interference coordination device.

The interference detection message is used for indicating the target cell to determine a first interference cell meeting a third preset condition. The third preset condition includes: the signal intensity of an interference signal sent by a first interference applying cell received on the target sub-frequency band is larger than a preset interference threshold value, and the network system of the first interference applying cell is different from that of the target cell. The target frequency sub-band is any frequency sub-band in the working frequency band of the target cell.

Step 402, the target cell determines a first disturbing cell meeting a third preset condition.

In one possible implementation, the target cell detects the signal strength of the interference signals from other cells on each sub-band in the operating band. And when the signal intensity of the disturbing cell received on any sub-frequency band in the working frequency band is greater than a preset interference threshold value and the network system of the disturbing cell is different from that of the target cell, taking the disturbing cell as a first disturbing cell and taking the sub-frequency band as an interference sub-frequency band of the first disturbing cell.

It should be noted that there may be one or more first interfering cells that cause interference to the target cell. A first interfering cell corresponds to an interfering sub-band.

Step 403, the target cell sends an interference response message to the interference coordination apparatus, and correspondingly, the interference coordination apparatus receives the interference response message sent by the target cell.

In a possible implementation manner, the interference response message further includes an interference sub-band of each first interfering cell.

And the interference sub-band of the first interference applying cell is the corresponding target sub-band when the signal intensity of the first interference applying cell received by the target cell is greater than a preset interference threshold value.

Based on the above technical solution, the interference coordination apparatus in the present application instructs the target cell to determine the first interfering cell causing interference to the target cell based on the signal strength of the interference signal by sending the interference detection message to the target cell, so as to perform interference coordination operation for the first interfering cell subsequently, and reduce signal interference received by the target cell. Meanwhile, the technical scheme of the invention can also exclude the cells with smaller interference influence on the target cell, reduce the number of first interference cells, and further reduce the signaling overhead and the realization complexity generated in the interference coordination process.

As a possible embodiment of the present application, in conjunction with fig. 2, as shown in fig. 4, before the above step 401, the method further includes the following step 404.

Step 404, the interference coordination apparatus sends an interference measurement message to the target cell.

The interference measurement message is used for instructing the target cell to determine the interference parameter of the target cell. The interference parameter includes at least one of a signal strength of an interference signal received on each sub-band in the working band, a cell identifier of a cell transmitting the interference signal, and a network type of the cell transmitting the interference signal.

For example, the interference signal may be an existing reference signal (reference signal), such as a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), or a reference signal newly introduced in the future.

The signal strength of the interference signal sent by the cell and received on each sub-band in the working band may be a mean value of signal strengths of a plurality of interference signals sent by the cell in a preset period.

In a possible implementation manner, the target cell may measure an interference parameter of the target cell through the interference measurement module.

The interference measurement module may be disposed at an access network device where the target cell is located, or may be disposed at a UE in the target cell. When the interference measurement module is disposed at the UE in the target cell, the interference measurement module may transmit the interference parameter to the target cell after measuring the interference parameter. In this way, the interference parameter of the target cell in the present application may be used to characterize signal interference received by the access network device where the target cell is located, and may also be used to characterize signal interference received by the UE in the target cell.

For example, the interference measurement module may also be simultaneously disposed at the access network device where the target cell is located and at the UE in the target cell, and determine the interference parameter of the target cell according to the first interference parameter measured by the interference measurement module located in the access network device and the second interference parameter measured by the interference measurement module located in the UE.

Based on the technical scheme, the method and the device can determine the signal interference condition of the target cell based on the granularity of the sub-frequency band, and further determine the first interference exerting cell according to the measured interference parameter of the target cell, so that the interference detection efficiency and accuracy are improved.

In the following, a process of the interference coordination apparatus acquiring the compensation cell corresponding to each first interfering cell is described.

As a possible embodiment of the present application, in conjunction with fig. 2, as shown in fig. 5, the above step 202 can also be implemented by the following steps 501 to 507.

Step 501, the interference coordination apparatus sends a first indication message to each first interfering cell. Correspondingly, the first interference cell receives a first indication message sent by the interference coordination device.

The first indication message is used for indicating the first disturbing cell to determine a candidate compensating cell meeting a fourth preset condition. The fourth preset condition includes: and the difference value between the measured signal intensity mean value of the first interference cell and the measured signal intensity mean value of the candidate compensation cell measured by the UE in the first interference cell is smaller than a first preset difference value. The first offending cell corresponds to one or more candidate compensating cells.

The first preset difference may be set according to practical situations, which is not limited in this application, and for understanding, only one first perturbation cell and one candidate compensation cell are shown in fig. 5.

Step 502, the first disturbing cell determines a candidate compensating cell meeting a fourth preset condition.

In a possible implementation manner, the first interfering cell acquires a measurement report of the UE that is accessed, and determines, according to the measurement report, a candidate compensating cell that satisfies a fourth preset condition.

The measurement report includes the signal strength of the first interfering cell and the signal strength of the neighboring cells except the first interfering cell measured by the UE.

And under the condition that the difference value between the signal intensity mean value of the first interference cell and the signal intensity mean value of the adjacent cell is smaller than a first preset difference value, the first interference cell determines the adjacent cell as a candidate compensation cell.

The mean value of the signal strength of the first disturbing cell is the mean value of the signal strength of the first disturbing cell measured by each accessed UE, and the mean value of the signal strength of the adjacent cell is the mean value of the signal strength of the adjacent cell measured by each accessed UE.

Step 503, the first disturbing cell sends a first response message to the interference coordination apparatus. Correspondingly, the interference coordination device receives a first response message sent by the first disturbing cell.

The first response message comprises cell identifications of candidate compensating cells corresponding to the first disturbing cell.

It should be noted that, when there are multiple first interfering cells, the interference coordination apparatus receives the first response message sent by each first interfering cell respectively.

Step 504, the interference coordination device sends a second indication message to each candidate compensation cell. Accordingly, the candidate compensating cell receives the second indication message sent by the interference coordination device.

Wherein the second indication message is used for indicating the candidate compensating cell to determine whether a fifth preset condition is met. The fifth preset condition includes: and the difference value between the measured signal intensity mean value of the candidate compensation cell and the measured signal intensity mean value of the first interference cell measured by the UE in the candidate compensation cell is less than a second preset difference value.

The second preset difference value can be set according to actual conditions, and the application does not limit the second preset difference value.

And step 505, the candidate compensation cell determines whether a fifth preset condition is met.

In a possible implementation manner, the candidate compensating cell acquires a measurement report of the UE that is accessed, and determines whether the fifth preset condition is satisfied according to the measurement report.

The measurement report includes the signal strength of the candidate compensating cell measured by the UE and the signal strength of the neighboring cells except the candidate compensating cell.

It should be noted that, some UEs in the candidate compensation cell can be the UEs that can measure the signal strength of the first interfering cell, and in this application, only the UEs in the candidate compensation cell that can measure the signal strength of the first interfering cell are referred to.

And under the condition that the difference value between the signal intensity mean value of the candidate compensation cell and the signal intensity mean value of the first disturbing cell is smaller than a second preset difference value, determining that the candidate compensation cell meets a fifth preset condition.

The mean value of the signal strengths of the candidate compensating cells is the mean value of the signal strengths of the candidate compensating cells measured by the UE capable of measuring the signal strength of the first interfering cell.

After determining that the fifth preset condition is satisfied, the candidate compensating cell further performs the following step 506.

Step 506, the candidate compensating cell sends a second response message to the interference coordination apparatus. Correspondingly, the interference coordination module receives a second response message sent by the candidate compensation cell.

Wherein the second response message includes cell identities of candidate compensatory cells satisfying a fifth preset condition.

It should be noted that, when there are a plurality of candidate compensation cells that satisfy the fifth preset condition, the interference coordination apparatus receives the second response message sent by each candidate compensation cell that satisfies the fifth preset condition.

Step 507, the interference coordination device determines the compensation cell corresponding to each first disturbing cell as a candidate compensation cell meeting a fifth preset condition.

Based on the above technical solution, the interference coordination apparatus in the present application may determine the compensation cell corresponding to each first disturbing cell through interaction between the first disturbing cell and the candidate compensation cell. Each determined compensation cell meets the condition that the signal intensity difference value between the compensation cell and the first interference cell respectively measured by the UE in the first interference cell is smaller than a first preset difference value, and also meets the condition that the signal intensity difference value between the compensation cell and the first interference cell respectively measured by the UE in the compensation cell is smaller than a second preset difference value. Therefore, the technical scheme of the application can ensure that the UE in the first disturbing cell is located in the wireless signal coverage area where the first disturbing cell and the compensation cell are overlapped, the success rate of UE in the disturbing cell migrating to the compensation cell is improved, and the network performance after UE switching is ensured.

In the following, a procedure of the interference coordination apparatus instructing one or more UEs in the second interfering cell to switch to the compensating cell corresponding to the second interfering cell is described.

As a possible embodiment of the present application, in conjunction with fig. 2, as shown in fig. 6, the above step 204 can also be implemented by the following steps 601 to 604.

Step 601, the interference coordination device sends a migration trigger message to each second disturbing cell. Correspondingly, the second interfering cell receives the migration trigger message sent by the interference coordination device.

And the migration trigger message is used for indicating the second interference cell to switch the second target UE to the first compensation cell. And the second target UE is the first N UEs in the second interference cell which are sequenced from high to low according to the target signal intensity. The target signal strength is the signal strength at which the signal strength values of the plurality of compensation cells measured by any UE in the second interfering cell are the maximum. N is a positive integer. The first compensating cell is a cell to be migrated by the second target UE.

It should be noted that the second target UEs correspond to the first compensation cells one to one, and the first compensation cells corresponding to each of the second target UEs in the plurality of second target UEs may be the same compensation cell or different compensation cells. The number of the second interfering cells may be one or more in the present application, and only one second interfering cell is shown in fig. 6 for ease of understanding.

Step 602, the second disturbing cell determines a second target UE to be migrated.

In a possible implementation manner, the second disturbing cell determines the number of second target UEs to be migrated according to the interfering sub-band and the operating frequency band of the second disturbing cell and the number of UEs in the second disturbing cell, and determines the second target UEs according to the signal strength values of the plurality of compensation cells measured by each UE in the second disturbing cell.

And the ratio of the number of the second target UEs to the number of the UEs in the second interference cell is equal to the bandwidth ratio of the interference sub-frequency band and the working frequency band of the second interference cell.

Illustratively, the number of second target UEs satisfies the following formula 1:

where N is the number of second target UEs, K ^‘ The bandwidth of the interference sub-band of the second interference cell, K the bandwidth of the working frequency band of the second interference cell, and M the number of UEs in the second interference cell.

As a possible embodiment, the second interfering cell may rank the accessed UEs from high to low according to the target signal strength, and use the first N UEs as the second target UE.

Wherein the target signal strength is the signal strength with the maximum signal strength value of the plurality of compensation cells measured by any UE in the second disturbing cell.

It should be noted that the target signal strength is higher, which indicates that the channel quality after the UE is switched to the compensation cell is better. By selecting the first N UEs with higher target signal strength as the second target UE, the technical scheme of the application can improve the transfer success rate of the second target UE and ensure the network performance of the second target UE after transfer.

When the UE measures the signal strengths of the plurality of signals of any one of the compensating cells within a preset period, the signal strength of the compensating cell measured by the UE is an average of the signal strengths of the plurality of signals.

Illustratively, the second interfering cell includes UE1, and the compensated cell measured by UE1 includes cell 1 and cell 2. The signal strengths of the signals of the cell 1 measured by the UE1 are { P11, P12, P13}, and the signal strengths of the signals of the cell 2 measured by the UE1 are { P21, P22, P23 }. Wherein, the signal strength P1 of cell 1 measured by the UE is (P11+ P12+ P13)/3, and the signal strength P2 of cell 2 measured by the UE is (P21+ P22+ P23)/3. If P1> P2, the target signal strength of UE1 is P1.

Step 603, the second disturbing cell sends a migration indication message to the second target UE, respectively. Correspondingly, the second target UE receives the migration indication message sent by the second disturbing cell.

And the migration indication message is used for indicating the second target UE to be switched to the first compensation cell. The migration indication message includes a cell identifier of a compensation cell corresponding to the second disturbing cell, a network type supported by the compensation cell, and an available capacity.

The second target UEs may be one or more in the present application, and only one second target UE is shown in fig. 6 for ease of understanding.

Step 604, the second target UE determines a first compensation cell to be migrated, and switches to the first compensation cell.

In a possible implementation manner, when the compensation cell corresponding to the second disturbing cell includes a cell satisfying a sixth preset condition, the first compensation cell is a cell satisfying the sixth preset condition.

When the compensation cell corresponding to the second disturbing cell includes a plurality of cells meeting a sixth preset condition, the first compensation cell is a cell with the largest compensation available capacity among the plurality of cells meeting the sixth preset condition.

Wherein the sixth preset condition comprises at least one of: the network standard supported by the compensation cell is included in the network standard supported by the second target UE, and the working frequency band supported by the compensation cell is included in the working frequency band supported by the second target UE.

It should be noted that the second target UE may determine the first compensation cell to be migrated according to the network standard, the working frequency band, and the available capacity supported by the compensation cell, so that the cell to be migrated meets the access requirement of the second target UE, and the normal access of the second target UE is ensured. Meanwhile, the second target UE determines the first compensation cell to be migrated, so that signaling overhead between the UE and the access network equipment and signaling overhead between the UE and the interference coordination device can be reduced, and UE migration efficiency is improved.

Illustratively, the network standard supported by the second target UE includes {3G, 4G }, the supported operating frequency band includes { band1, band3}, the network standard supported by the compensating cell 1 includes {3G }, and the operating frequency band supported by the compensating cell 1 includes { band1 }. The network standard supported by the compensation cell 1 is included in the network standard supported by the second target UE, and the working frequency band supported by the compensation cell 1 is included in the working frequency band supported by the second target UE.

Based on the above technical solution, before instructing the second interfering cell to perform the interference coordination operation, the interference coordination apparatus in the present application may instruct one or more UEs in the second interfering cell to migrate to the corresponding compensation cell. The UE to be migrated can be determined according to the interference sub-band bandwidth of the second interfering cell. When the interference sub-band bandwidth of the second interfering cell is larger, the spectrum resources closed when the second interfering cell performs the interference coordination operation are more, and thus the spectrum resources used by the second interfering cell are less. Therefore, the number of the target UEs to be migrated is determined based on the interference sub-bands, so that the available spectrum resources of the second interference cell can be matched with the data transmission requirements of the UEs in the second interference cell, and the service requirements of users are guaranteed.
