[0066] Currently, there are two main types of 5G wireless solutions for private networks. The first reuses existing public network resources, allowing public and private network services to transmit data in the same cell, while relying on technologies such as Quality of Service (QoS) to ensure the reliability of private network data transmission. The second type deploys independent cells for private networks and independently schedules frequency resources to ensure air interface quality. Neither of these two solutions can predict or eliminate interference caused by fluctuating traffic volumes in co-frequency neighboring cells deployed closely outside the private network. When traffic volumes in co-frequency neighboring cells are high, air interface quality deteriorates, resulting in the private network's performance indicators failing to meet the application requirements of the corresponding industry.

[0067] Based on this, in various embodiments of the present application, the first base station reports first information to the first core network device; the first information includes the neighboring area measurement results of the terminal accessing the first base station, the uplink noise floor of the first base station and the frequency range that needs to be guaranteed; based on the uplink noise floor and the neighboring area measurement results, the first core network device determines at least one neighboring area from the neighboring areas included in the neighboring area measurement results, and sends the frequency range to at least one second base station to which the at least one neighboring area belongs; the sent frequency range is used for each of the at least one second base station to perform access restriction within the frequency range.

[0068] The embodiment of the present application provides a method for eliminating cell interference, which is applied to a first core network device, such as Figure 1 As shown, the method includes:

[0069] Step 101: Receive first information reported by a first base station.

[0070] The first information includes: a neighboring cell measurement result of a terminal accessing the first base station, an uplink noise floor of the first base station, and a frequency range that needs to be guaranteed.

[0071] Here, the terminal accessing the first base station reports the neighboring cell measurement results of the terminal to the first base station. The neighboring cell measurement results include the neighboring cell identifier and the corresponding measurement value (for example, Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (RSRQ)). The first base station reports the neighboring cell measurement results reported by each terminal in at least one received terminal to the first core network device. The uplink background noise reported by the first base station is the background noise of the uplink channel between the first base station and the terminal, which is measured by the first base station. The frequency range that needs to be guaranteed is determined by the first base station based on the frequency resources allocated to the access terminal, and is the frequency range for which the first base station needs to prioritize the transmission quality.

[0072] Among them, considering that the air interface interference caused by the different-frequency neighboring cells to the terminal service cell is relatively small, in actual applications, the neighboring cell measurement results reported by the first base station to the first core network device can be the same-frequency neighboring cell measurement results.

[0073] Step 102: Based on the uplink noise floor and the neighboring cell measurement result, determine at least one neighboring cell from the neighboring cells included in the neighboring cell measurement result.

[0074] Here, in the first information reported by the first base station, the uplink noise floor of the first base station reflects the channel quality of the uplink channel between the first base station and the terminal, and the neighboring cell measurement result reflects the channel quality of the downlink channel between the first base station and the terminal. The first core network device determines the air interface interference caused by the co-frequency neighboring cell to the uplink channel between the first base station and the terminal based on the uplink noise floor in the first information, and determines the air interface interference caused by the co-frequency neighboring cell to the downlink channel between the first base station and the terminal based on the neighboring cell measurement result in the first information, thereby obtaining a judgment result. The judgment result includes: whether frequency resources are guaranteed for the first base station, and, when the judgment result indicates that frequency resources need to be guaranteed for the first base station, which neighboring cells of the first base station are to be adjusted for frequency resources, thereby determining a list of neighboring cells whose frequency resources need to be adjusted.

[0075] In actual application, the first core network device filters out neighboring cells with high signal strength based on the measurement values ​​in the neighboring cell measurement results to obtain a neighboring cell list.

[0076] Step 103: Send the frequency range to at least one second base station to which the at least one neighboring cell belongs.

[0077] The sent frequency range is used for each of the at least one second base station to perform access restriction within the frequency range.

[0078] Here, the first core network device determines the list of neighboring cells that need to adjust frequency resources, and sends the frequency range to the second base station to which the cells in the neighboring cell list belong. The frequency range is the frequency range that needs to be guaranteed as reported by the first base station. After obtaining the frequency range sent by the first core network device, the second base station adopts a method based on bandwidth part (BWP, BandWidth Part) guarantee or a method based on handover resource reservation to restrict access within the frequency range that needs to be guaranteed, thereby achieving frequency resource adjustment, achieving air interface quality assurance for the first base station, and ensuring the data transmission quality of the first base station.

[0079] Among them, the BWP guarantee-based method is to issue BWP configuration to the cell under the second base station, allowing cell users to access the designated frequency band. Here, the designated frequency band is a frequency band different from the frequency range that needs to be protected, so as to limit the cell users from accessing the frequency range that needs to be protected; the switching resource reservation-based method is to divide the frequency band corresponding to the frequency range that needs to be protected for the cell under the second base station, and the cell users are not allowed to access the divided frequency band, so as to limit the cell users from accessing the frequency range that needs to be protected.

[0080] In actual application, data exchange is performed between the first core network device and the first base station through the Ng interface.

[0081] By implementing the solution of the embodiments of the present application, it is possible to restrict access to the frequency range that needs to be protected by the first base station on the second base station, thereby achieving air interface quality assurance for the first base station and ensuring the data transmission quality of the first base station. In actual application, it is possible to restrict access to the frequency range that needs to be protected by the base station with relatively high air interface quality requirements on the neighboring base station with relatively low air interface quality requirements.

[0082] Based on this, in one embodiment, determining at least one neighboring cell from the neighboring cells included in the neighboring cell measurement result based on the uplink noise floor and the neighboring cell measurement result includes:

[0083] Filtering out, from the neighboring cells included in the neighboring cell measurement result, neighboring cells under the base station having a second priority;

[0084] Based on the uplink noise floor and the neighboring cell measurement result, the at least one neighboring cell is determined from the filtered neighboring cells; wherein,

[0085] The priority of the first base station is a first priority; the first priority is greater than the second priority.

[0086] Here, the requirements of the base station for air interface quality are differentiated based on the set priority, and the first priority corresponding to the base station with relatively high air interface quality requirements is higher than the second priority corresponding to the base station with relatively low air interface quality requirements. In this way, the first core network device, according to the corresponding priority, screens out the neighboring areas under the base station with relatively low air interface quality requirements from the neighboring areas included in the neighboring area measurement results reported by the base station with relatively high air interface quality requirements, and then determines at least one neighboring area from the screened neighboring areas based on the uplink background noise and neighboring area measurement results reported by the base station with relatively high air interface quality requirements, and restricts access to the corresponding neighboring area users within the frequency range that needs to be protected.

[0087] In actual application, the core network side configures a corresponding priority for each base station based on the requirements of each base station for air interface quality, so as to identify the requirements of each base station for air interface quality through the priority.

[0088] Based on this, in one embodiment, the method further includes:

[0089] Storing the priority corresponding to each base station in at least one base station; wherein,

[0090] The priority includes the first priority and the second priority.

[0091] Here, the first core network device determines the priority of the base station to which the cell belongs based on the cell identifier in the network, and stores the priority of the base station in the first core network device. In actual application, the first core network device may also store the priority of each cell, where the priority of the cell is the same as the priority of the base station to which the cell belongs. In this way, the first core network device can implement frequency resource guarantee for high-priority base stations based on the stored priorities.

[0092] In actual applications, the priority level of a base station is determined based on the data transmission requirements or air interface quality requirements corresponding to the network type deployed on the base station. Based on this, in one embodiment, the first core network device stores priorities for private network base stations corresponding to the first priority level, while public network base stations correspond to the second priority level. This allows the first core network device to guarantee frequency resources for private network base stations with higher air interface quality requirements based on the stored priorities.

[0093] Here, private network base stations include but are not limited to base stations deployed in industry-specific networks such as enterprise networks, government networks, and campus networks.

[0094] In actual application, a trigger condition is set, and when the trigger condition is met, the first base station is triggered to report the first information to the first core network device, so that the first core network device starts frequency resource guarantee for the first base station.

[0095] Based on this, in one embodiment, the receiving of the first information reported by the first base station includes:

[0096] Sending a first instruction to the first base station, where the first instruction is used to instruct the first base station to report the first information after receiving the first instruction;

[0097] Receive the first information reported by the first base station based on the first instruction.

[0098] Here, the first instruction represents the first core network device sending a query instruction to the first base station, triggering the first base station to report the first information through the query instruction. In actual applications, the first core network device may periodically send query instructions to the first base station. In addition, in actual applications, the first core network device may send query instructions to base stations with relatively high air interface quality requirements based on stored priorities.

[0099] In actual application, after receiving the first information reported by the first base station, the first core network device determines whether the first base station needs frequency resource protection based on the first information, and initiates frequency resource adjustment for the first base station if the judgment result indicates that frequency resource protection for the first base station is needed.

[0100] Based on this, in one embodiment, determining at least one neighboring cell from the neighboring cells included in the neighboring cell measurement result based on the uplink noise floor and the neighboring cell measurement result includes:

[0101] When the first parameter is greater than the set threshold, based on the uplink noise floor and the neighboring cell measurement result, at least one neighboring cell is determined from the neighboring cells included in the neighboring cell measurement result; wherein,

[0102] The first parameter is determined based on the uplink noise floor.

[0103] Here, the first core network device determines the first parameter based on the uplink background noise, and further determines whether the first parameter is greater than the set threshold corresponding to the first parameter. When the first parameter is greater than the corresponding set threshold, it is determined that the neighboring area has caused greater air interface interference to the cell under the first base station. Therefore, the first core network device starts frequency resource protection for the first base station in order to promptly eliminate the cell interference caused by the neighboring area to the cell under the first base station.

[0104] The first parameter may be the uplink noise floor, or other parameter determined based on the uplink noise floor. For example, the signal-to-noise ratio of the uplink channel between the first base station and the terminal is determined based on the uplink noise floor of the first base station.

[0105] When implementing the solution of the embodiment of the present application, the first core network device can be implemented by adding a corresponding frequency resource guarantee function module in the relevant core network device, or, it can also be considered to introduce an independent core network device at the gateway of the core network, specifically for implementing the frequency resource guarantee function.

[0106] Based on this, in one embodiment, the sending the frequency range to at least one second base station includes:

[0107] directly delivering the frequency range to the at least one second base station; or,

[0108] The frequency range is delivered to the at least one second base station through the second core network device.

[0109] Among them, when adding the frequency resource guarantee function to the core network equipment of the existing network, the first core network equipment directly sends the frequency range that needs to be guaranteed to the second base station through the Ng interface. When an independent core network equipment specifically used to implement the frequency resource guarantee function is introduced, the first core network equipment sends the neighboring cell list and the frequency range that needs to be guaranteed to the core network equipment of the existing network, and the core network equipment of the existing network sends the frequency range that needs to be guaranteed to the corresponding second base station through the Ng interface.

[0110] The embodiment of the present application provides a method for eliminating cell interference, which is applied to a first base station, such as Figure 2 As shown, the method includes:

[0111] Step 201: Report first information.

[0112] The first information includes: a neighboring cell measurement result of a terminal accessing the first base station, an uplink noise floor of the first base station, and a frequency range that needs to be guaranteed; the first information is used for the first core network device to determine at least one neighboring cell from the neighboring cells included in the neighboring cell measurement result based on the uplink noise floor and the neighboring cell measurement result, and to send the frequency range to at least one second base station to which the at least one neighboring cell belongs; the sent frequency range is used for each of the at least one second base station to perform access restriction within the frequency range.

[0113] Here, the terminal accessing the first base station reports the neighboring cell measurement results of the terminal to the first base station. The neighboring cell measurement results include the neighboring cell identifier and the corresponding measurement value (such as RSRP or RSRQ, Reference Signal ReceivingQuality). The first base station reports the neighboring cell measurement results reported by each terminal among the at least one terminal received to the first core network device. The uplink noise floor reported by the first base station is the background noise of the uplink channel between the first base station and the terminal, which is measured by the first base station. The frequency range that needs to be guaranteed is determined by the first base station based on the frequency resources allocated to the access terminal, and is the frequency range for which the first base station needs to prioritize the transmission quality.

[0114] Among them, considering that the air interface interference caused by the different-frequency neighboring cells to the terminal service cell is relatively small, in actual applications, the neighboring cell measurement results reported by the first base station to the first core network device can be the same-frequency neighboring cell measurement results.

[0115] In the first information reported by the first base station, the uplink noise floor of the first base station reflects the channel quality of the uplink channel between the first base station and the terminal, and the neighboring cell measurement result reflects the channel quality of the downlink channel between the first base station and the terminal. Based on the uplink noise floor in the first information, the first core network device determines the air interface interference caused by co-frequency neighboring cells on the uplink channel between the first base station and the terminal. Based on the neighboring cell measurement result in the first information, the first core network device determines the air interface interference caused by co-frequency neighboring cells on the downlink channel between the first base station and the terminal, thereby obtaining a decision result. The decision result includes whether to guarantee frequency resources for the first base station and, if the decision result indicates that frequency resources need to be guaranteed for the first base station, which neighboring cells of the first base station should have their frequency resources adjusted, thereby determining a list of neighboring cells requiring frequency resource adjustment. The first core network device then determines the list of neighboring cells requiring frequency resource adjustment and sends the frequency range to the second base station to which the cells in the neighboring cell list belong. The frequency range is the frequency range required to be guaranteed as reported by the first base station. After obtaining the frequency range sent by the first core network device, the second base station uses a BWP guarantee-based method or a handover resource reservation-based method to restrict access within the frequency range that needs to be guaranteed.

[0116] In actual application, data is exchanged between the first core network device and the first base station via the Ng interface. The first base station can be a private network base station with high air interface quality requirements. Here, private network base stations include but are not limited to base stations deployed in industry-specific networks such as enterprise networks, government networks, and campus networks.

[0117] In actual application, a trigger condition is set, and when the trigger condition is met, the first base station is triggered to report the first information to the first core network device, so that the first core network device starts frequency resource guarantee for the first base station.

[0118] Based on this, in one embodiment, reporting the first information includes:

[0119] receiving a first instruction from the first core network device; the first instruction is used to instruct the first base station to report the first information after receiving the first instruction;

[0120] Report the first information based on the first instruction.

[0121] Here, the first instruction represents that the first core network device sends a query instruction to the first base station, and the query instruction triggers the first base station to report the first information. In actual application, the first core network device can periodically send query instructions to the first base station.

[0122] In actual applications, when the first base station triggers reporting of the first information to the first core network device, it starts measuring the uplink noise floor and reports the neighboring cell measurement result of the terminal. Based on this, in one embodiment, reporting the first information includes:

[0123] When the number of terminals accessing the first base station and in a connected state is greater than or equal to 1, the first information is reported.

[0124] Here, the number of terminals connected to the first base station and in a connected state is greater than or equal to 1, indicating that the first base station currently has uplink and downlink services and that air interface interference caused by neighboring cells needs to be evaluated in order to ensure frequency resources.

[0125] The present application will be further described in detail below in conjunction with application examples.

[0126] Combine Figure 3 , the corresponding application embodiment of the method for eliminating cell interference includes the following steps:

[0127] Step 1: Deploy a cell for the industry-specific network.

[0128] Step 2: If the number of terminals connected to the cell and in the connected state is greater than or equal to 1, it means that the cell has services, and step 3 is executed.

[0129] Step 3: The terminal accessing the cell performs intra-frequency measurement and reports the intra-frequency measurement result to the cell.

[0130] Step 4: The cell base station reports first information to the core network. The first information includes the same-frequency measurement result, the uplink noise floor of the base station, and the frequency range that needs to be guaranteed.

[0131] Here, the cell base station can also make its own judgment based on the same-frequency measurement results and the uplink noise floor to determine whether there is cell interference in the corresponding uplink and downlink channels, and report the same-frequency measurement results, uplink noise floor and frequency range that needs to be protected to the core network after determining that cell interference exists.

[0132] Step 5: The core network makes a decision based on the information reported by the cell base station and obtains a list of cells that require frequency resource adjustment.

[0133] Step 6: The core network sends the frequency range that needs to be protected to the base stations of the cells in the cell list.

[0134] Step 7: The base stations of the cells in the cell list restrict access to the cell users based on the frequency range that needs to be protected.

[0135] When adding frequency resource guarantee function to the core network equipment of the existing network, combined with Figure 4 , the corresponding application embodiment of the method for eliminating cell interference includes the following steps:

[0136] Step 1: The core network device sends a query instruction to the first base station.

[0137] Step 2: The first base station reports the first information to the core network device based on the query instruction.

[0138] Step 3: The core network device obtains a judgment result based on the first information.

[0139] Step 4: The core network device sends the judgment result to the relevant second base station.

[0140] Step 5: The second base station restricts access to the cell users.

[0141] In the case of introducing independent core network equipment dedicated to realizing frequency resource guarantee function, combined with Figure 5 , the corresponding application embodiment of the method for eliminating cell interference includes the following steps:

[0142] Step 1: The first core network device sends a query instruction to the first base station.

[0143] Step 2: The first base station reports the first information to the first core network device based on the query instruction.
