[0061] Those skilled in the art will understand that Figure 1The structure shown in the figure does not constitute a limitation to the spectrum sharing device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0062] Spectrum resources, as the carrier of information transmission, are a core resource for mobile communications. To meet service needs and improve spectrum resource utilization, different network standards share the same spectrum resources, a practice known as spectrum sharing. Currently, spectrum sharing primarily includes static and dynamic spectrum sharing. Static spectrum sharing allocates fixed spectrum resources to different network standards, and at the same time, the spectrum resources of different network standards have no overlapping spectrum areas. As the network standard load changes, this spectrum sharing method will cause spectrum resources to be idle, resulting in spectrum resource waste. For example, for the LTE (Long Term Evolution, also known as 4G) network standard and the NR (New Radio, also known as 5G) network standard, static spectrum sharing is adopted. In the early stage of 5G network construction, there will be fewer users accessing the 5G network and more users accessing the 4G network. The 4G spectrum resource load will be high and the 5G spectrum resource load will be low, resulting in resource waste and an inability to meet the business needs of 4G users. As the 5G network construction gradually matures, there will be more users accessing the 5G network and fewer users accessing the 4G network. The 5G spectrum resource load will be high and the 4G spectrum resource load will be low, resulting in resource waste and an inability to meet the business needs of 5G users. Dynamic spectrum sharing refers to the dynamic sharing of spectrum resources among different network standards. The method is mainly based on the business needs of one network standard, and spectrum resources are allocated to one network standard first, and the remaining spectrum resources are allocated to the other network standard. However, this will lead to the situation that the other network standard cannot meet the business needs; for example, for LTE network standards and NR network standards, spectrum resources are allocated to LTE network standards first based on LTE's business needs. Since in the early stages of 5G construction, 4G networks are usually in a high-load state, there are few surplus spectrum resources, resulting in fewer 5G spectrum resources and an inability to meet the business needs of 5G users.

[0063] It can be seen that the existing spectrum resource sharing method is unreasonable, resulting in spectrum resource waste and inability to meet business needs.

[0064] In order to solve the above technical problems, various embodiments of the present invention are proposed based on the above hardware structure.

[0065] Spectrum sharing method embodiment:

[0066] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a spectrum sharing method according to the present invention. In the embodiment of the present invention, the spectrum sharing method includes the following steps:

[0067] Step S21: Determine a shared cell set based on the target cell and the neighboring cells of the target cell.

[0068] The shared cell set includes cells of the first network standard and cells of the second network standard.

[0069] It should be noted that the network standard is the type of communication network, such as an LTE network, an NR network, a CDMA (Code Division Multiple Access) network, etc. The first network standard and the second network standard are two network standards that can share spectrum. For example, since the spectrum supported by NR FDD (Frequency Division Duplexing) and LTE FDD overlaps, and both use the FDD mode for communication, NR FDD and LTE FDD can share the spectrum. Therefore, the first network standard and the second network standard can be NR FDD and LTE FDD. Among them, the first network standard can be the network standard with an earlier announcement time among the two network standards for spectrum sharing, and the second network standard can be the network standard with a later announcement time among the two network standards for spectrum sharing, for example, the first network standard is LTE FDD and the second network standard is NR FDD; or, the first network standard can be the network standard with a later announcement time among the two network standards for spectrum sharing, and the second network standard can be the network standard with an earlier announcement time among the two network standards for spectrum sharing, for example, the first network standard is NR FDD and the second network standard is LTE FDD.

[0070] The first network standard cell is a cell that uses the first network standard for communication, and the second network standard cell is a cell that uses the second network communication standard for communication.

[0071] The shared cell set may be a list, that is, the shared cell set is a shared cell list. Of course, the shared cell set may also be in other forms.

[0072] The target cell is a cell in the communication network. The target cell can be a cell of any network standard in the communication network. Alternatively, considering that a cell of a first network standard and a cell of a second network standard can share spectrum, the target cell can be a cell of the first network standard, or the target cell can be a cell of the second network standard, or the target cell can include cells of the first network standard and cells of the second network standard.

[0073] In the embodiment of the present invention, a target cell and neighboring cells of the target cell are determined, and a shared cell set is determined based on the target cell and the neighboring cells of the target cell. Since the communication network includes cells of the first network standard and cells of the second network standard, and the target cell or neighboring cells of the target cell include cells of the first network standard and cells of the second network standard, the shared cell set also includes cells of the first network standard and cells of the second network standard.

[0074] The method for determining the neighboring cells of the target cell can be flexibly set according to actual needs, and the method for determining the shared cell set based on the target cell and the neighboring cells of the target cell can also be flexibly set according to actual needs. For example, in one example, the target cell and the neighboring cells of the target cell can be added to the shared cell set. Alternatively, in another example, the neighboring cells of the target cell can be screened based on a preset screening rule, and the neighboring cells of the target cell and the target cell that have been screened out can be added to the shared cell set. The preset screening rule can be flexibly set according to actual needs. For example, in one example, considering that the spectrum sharing range includes the first network standard cell and the second network standard cell, there may be cells other than the first network standard cell and the second network standard cell among the target cell and the neighboring cells of the target cell. Therefore, the preset screening rule can be to screen out the first network standard cell and the second network standard cell, that is, to screen out the first network standard cell and the second network standard cell from the target cell and the neighboring cells of the target cell, and add the screened cells to the shared cell set, that is, the shared cell set only includes the first network standard cell and the second network standard cell.

[0075] Step S22: Obtain the load of the cell of the first network standard and the load of the cell of the second network standard to obtain a first load and a second load.

[0076] Load is a parameter that characterizes throughput and can reflect service demand. Load can be parameters that characterize the cell's throughput, such as downlink throughput, uplink throughput, and spectrum efficiency. Spectral efficiency can be either downlink or uplink spectrum efficiency. Spectral efficiency = net data rate / spectrum bandwidth; uplink spectrum efficiency = uplink net data rate / spectrum bandwidth; downlink spectrum efficiency = downlink net data rate / spectrum bandwidth. It should be understood that during data transmission, in addition to the data being transmitted, there is also additional overhead. Net data rate = data rate - overhead; uplink net data rate = uplink data rate - overhead; downlink net data rate = downlink data rate - overhead.

[0077] In an embodiment of the present invention, in determining a shared cell set, the load of a cell of a first network standard in the shared cell set is obtained to obtain a first load, and the load of a cell of a second network standard in the shared cell set is obtained to obtain a second load.

[0078] It should be noted that there may be multiple (in the embodiment of the present invention, multiple specifically refers to two or at least two) first network standard cells in the shared cell set. When there are multiple first network standard cells, the first load is the total load of the multiple first network standard cells. For example, when the load is the downlink throughput rate, the downlink throughput speed of each first network standard cell can be obtained, and the sum of the downlink throughput rates of each first network standard cell can be used as the first load. Alternatively, when the load is the downlink spectrum efficiency, the downlink net data rate of each first network standard cell can be obtained, and the sum of the downlink net data rates of each first network standard cell can be obtained, and the ratio of the sum of the downlink net data rates to the spectrum bandwidth occupied by each first network standard cell can be used as the first load. Similarly, when there are multiple second network standard cells in the shared cell set, the second load is the total load of the multiple second network standard cells.

[0079] In some embodiments, if spectrum resources have not been allocated to the first network standard cell or the second network standard cell before step S22, spectrum resources of a preset bandwidth may be allocated to the first network standard cell or the second network standard cell first, and then step S22 may be performed, wherein the preset bandwidth may be flexibly set according to actual needs. For example, assuming that the first network standard cell and the second network standard cell are NR FDD cells or LTE FDD cells, if spectrum resources have not been allocated to the NR FDD cell before step S22, spectrum resources of a preset bandwidth may be allocated to the NR FDD cell, and then step S22 may be performed.

[0080] Step S23: Based on the ratio of the first load to the second load, determine the ratio of the spectrum resources of the cell of the first network standard to the spectrum resources of the cell of the second network standard to obtain a target ratio.

[0081] In an embodiment of the present invention, after determining the first load and the second load, the ratio of the first load and the second load is obtained, and based on the ratio of the first load and the second load, the ratio of the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell is determined to obtain the target ratio.

[0082] The specific determination method can be flexibly set according to actual needs. In one example, the ratio of the first load to the second load can be directly used as the target ratio. That is, the relationship between the first load, the second load, the spectrum resources of the first network standard cell, the spectrum resources of the second network standard cell, and the target ratio can be as follows:

[0083] Target ratio=first load / second load=spectrum resources of the cell of the first network standard / spectrum resources of the cell of the second network standard.

[0084] Step S24: Based on the target ratio and the shared spectrum resources, the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell are set.

[0085] The shared spectrum resources are spectrum resources shared by the first network standard cell and the second network standard cell in the shared cell set.

[0086] In the embodiment of the present invention, after the target ratio is determined, the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell are set based on the target ratio and the shared spectrum resources.

[0087] The specific configuration can be flexibly set based on actual needs. For example, based on a target ratio, shared spectrum resources can be allocated to a first network standard cell and a second network standard cell, such that the ratio of the spectrum resources allocated to the first network standard cell to the spectrum resources allocated to the second network standard cell equals the target ratio, and the sum of the spectrum resources allocated to the first network standard cell and the spectrum resources allocated to the second network standard cell equals the shared spectrum resources. In an example, assuming that the frequency band of the shared spectrum resource is 1710MHz-1730MHz, the bandwidth is 20MHz, the first network standard cell is an LTE FDD cell, the second network standard cell is an NR FDD cell, the target ratio is 2:3, and the shared cell set includes 20 LTE FDD cells and 30 NR FDD cells. The spectrum resource bandwidth of the LTE FDD cell is 8MHz, and the spectrum resource bandwidth of the NR FDD cell is 12MHz. The spectrum resource bandwidth allocated to the 20 LTE FDD cells is 8MHz, and the spectrum resource bandwidth allocated to the 30 NR FDD cells is 12MHz. For example, the carrier frequency bands of these 20 LTE FDD cells can be set to 1710MHz-1718MHz, and the carrier frequency bands of these 30 NR FDD cells can be set to 1718MHz-1730MHz.

[0088] It should be noted that in an embodiment of the present invention, when the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell are set based on the target ratio and shared spectrum resources, the spectrum resources allocated to the first network standard cell and the second network standard cell can be at the carrier level or at the PRB (physical resource block) level.

[0089] In some implementations, considering that the load of the cell may vary, steps S22 to S24 may be performed periodically, for example, steps S22 to S24 may be performed every other day.

[0090] In some embodiments, considering that the target cell and the neighboring cells of the target cell may change with the development of communication construction, in order to adapt to such changes, steps S21 to S24 can be performed periodically. The period can be flexibly set according to actual needs. For example, steps S21 to S24 can be performed once every month.

[0091] In the spectrum sharing method provided by an embodiment of the present invention, a shared cell set is determined based on a target cell and neighboring cells of the target cell; wherein the shared cell set includes a first network standard cell and a second network standard cell; the load of the first network standard cell and the load of the second network standard cell are obtained to obtain the first load and the second load, and based on the ratio of the first load and the second load, the ratio of the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell is determined to obtain the target ratio, and based on the target ratio and the shared spectrum resources, the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell are set, and the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell are determined by the ratio between the load of the first network standard cell and the load of the second network standard cell. This not only allows the allocated spectrum resources to meet the business needs of each network standard cell and ensure the user experience of the first network standard users and the second network standard users, but also avoids the waste of spectrum resources, improves the utilization rate of spectrum resources, and improves the communication quality.

[0092] Based on the first embodiment, a second embodiment of the spectrum sharing method of the present invention is proposed. Figure 3 , Figure 3 FIG2 is a flow chart of a second embodiment of a spectrum sharing method according to the present invention. In the embodiment of the present invention, step S21 includes:

[0093] Step S211: Obtain at least one measurement report reported by the target terminal.

[0094] It should be noted that the target terminal is a terminal whose serving cell is the target cell. The number of target terminals is determined based on the number of terminals accessing the target cell and can be one or more. The measurement report reported by the target terminal includes the serving cell of the target terminal, the neighboring cells of the serving cell, the RSRP (Reference Signal Receiving Power) value of the serving cell, and the RSRP value of the neighboring cells of the serving cell.

[0095] It should be understood that when a terminal accesses a target cell, the serving cell of the terminal becomes the target cell, and the terminal becomes the target terminal. The target terminal measures the RSRP value of its serving cell and the RSRP value of the neighboring cells of the serving cell and forms a measurement report for reporting. A target terminal may periodically report a measurement report. In an embodiment of the present invention, at least one measurement report reported by the target terminal is obtained.

[0096] The measurement reports reported by the target terminal within the preset collection time period can be obtained, thereby obtaining multiple measurement reports. The preset collection time period can be flexibly set according to actual needs, for example, it can be set to 10 minutes, 1 hour, etc.

[0097] Step S212: For each measurement report, if in the measurement report, the RSRP value of the serving cell is greater than the preset first RSRP value, and the absolute value of the difference between the RSRP value of the serving cell and the RSRP value of the neighboring cell of the serving cell is less than the preset second RSRP value, then the serving cell and the neighboring cell of the serving cell are added to the shared cell set.

[0098] The specific values of the preset first RSRP value and the preset second RSRP value can be flexibly set according to actual needs. For example, the preset first RSRP value can be -110dBm, and the preset second RSRP value can be 6dB.

[0099] In an embodiment of the present invention, after obtaining at least one measurement report, for each measurement report, if, in the measurement report, the RSRP value of the serving cell is greater than a preset first RSRP value, and the absolute value of the difference between the RSRP value of the serving cell and the RSRP value of the serving cell's neighboring cells is less than a preset second RSRP value, then the serving cell and the serving cell's neighboring cells are added to the shared cell set. Since the serving cell in the measurement report is the target cell, the serving cell's neighboring cells are the target cell's neighboring cells, and step S12 is, if, in the measurement report, the target cell's RSRP value is greater than the preset first RSRP value, and the absolute value of the difference between the RSRP value of the target cell and the RSRP value of the target cell's neighboring cells is less than a preset second RSRP value, then the target cell and the target cell's neighboring cells are added to the shared cell set.

[0100] It should be noted that, since the neighboring cells of the serving cell may overlap in the measurement reports reported by different target terminals, after step S212 , the shared cell set may be deduplicated.

[0101] For a better understanding, an example is used here to illustrate. Assume that the preset first RSRP value is -110dBm, the preset second RSRP value is 6dB, the target cell is cell 1, and three measurement reports reported by the target terminal are obtained. The parameters of the first measurement report are shown in Table 1, the parameters of the second measurement report are shown in Table 2, and the parameters of the third measurement report are shown in Table 3. Since the RSRP value of the serving cell in the third measurement report is less than the preset first RSRP value, the cells in the third measurement report are not added to the shared cell list; cell 1, cell 2, cell 3, cell 4, cell 5, cell 6, and cell 7 are added to the shared cell list.

[0108]

[0109] In some implementations, considering that the scope of spectrum resource sharing is the first network standard cell and the second network standard cell, after obtaining the shared cell set, the cells in the shared cell set outside the first network standard cell and the second network standard cell can be deleted.

[0110] In the spectrum sharing method provided in an embodiment of the present invention, at least one measurement report reported by the target terminal is obtained, wherein the target terminal is a terminal whose serving cell is the target cell, and the measurement report includes the RSRP value of the serving cell of the target terminal and the RSRP value of the neighboring cell of the serving cell; for each measurement report, if in the measurement report, the RSRP value of the serving cell is greater than a preset first RSRP value, and the absolute value of the difference between the RSRP value of the serving cell and the RSRP value of the neighboring cell of the serving cell is less than a preset second RSRP value, then the serving cell and the neighboring cell of the serving cell are added to the shared cell set, that is, in an embodiment of the present invention, the RSRP value of the target cell and the RSRP value of the neighboring cell of the target cell are obtained through the measurement report, and the neighboring cells are screened based on the RSRP value, so as to determine the shared cell set for spectrum resource sharing and improve the accuracy.

[0111] Based on the second embodiment, a third embodiment of the spectrum sharing method of the present invention is proposed. Figure 4 , Figure 4This is a flow chart of a third embodiment of the spectrum sharing method of the present invention. In this embodiment of the present invention, before step S22, the following steps are further included:

[0112] Step S25: Obtain the total number of cells in the shared cell set and the total number of cells in at least one measurement report.

[0113] In the embodiment of the present invention, in order to determine the overlapping coverage of the target cell, the number of cells in the shared cell set and the total number of cells in the at least one measurement report obtained in step S211 are obtained.

[0114] It should be noted that when obtaining the total number of cells in at least one measurement report, taking into account that the cells included in different measurement reports may overlap, when obtaining the total number of cells in at least one measurement report, the cells included in at least one measurement report can be deduplicated and then the total number of cells can be determined.

[0115] Step S26: Determine whether the ratio between the number of cells in the shared cell set and the total number of cells is greater than a preset threshold.

[0116] The preset threshold value can be flexibly set according to actual needs, for example, it can be set to 15%.

[0117] In the embodiment of the present invention, a ratio between the number of cells in the shared cell set and the total number of cells is obtained, and it is determined whether the ratio is greater than a preset threshold.

[0118] For example, assuming that in the ratio S211, two measurement reports are obtained, the first measurement report includes cells a, b, and c, and the second measurement report includes cells c, d, e, and f. The shared cell set includes cells b, c, and d. The number of cells in the shared cell set is 3, and the total number of cells is 6. Determine whether 3 / 6 is greater than the preset threshold value.

[0119] Step S27: If yes, the step of acquiring the load of the cell of the first network standard and the load of the cell of the second network standard is performed to obtain the first load and the second load.

[0120] In the embodiment of the present invention, if the ratio between the number of cells in the shared cell set and the total number of cells is greater than a preset threshold, step S22 is executed.

[0121] In the spectrum sharing method provided in an embodiment of the present invention, the number of cells in the shared cell set and the total number of cells in at least one measurement report are obtained, and it is determined whether the ratio between the number of cells in the shared cell set and the total number of cells is greater than a preset threshold value. If so, the load of the first network standard cell and the load of the second network standard cell are obtained to obtain the first load and the second load and subsequent steps, thereby avoiding the situation where resource sharing cannot be performed when the overlapping coverage of the target cell is low.

[0122] Based on the above embodiments, a fourth embodiment of the spectrum sharing method of the present invention is proposed. In this embodiment of the present invention, step S22 includes but is not limited to the following two methods.

[0123] In the first approach, step S22 includes:

[0124] Step S221: periodically obtain the load of the cell of the first network standard and the load of the cell of the second network standard.

[0125] The period for obtaining the load may be flexibly set according to actual needs. For example, the load of the first network standard cell and the load of the second network standard cell may be obtained once every hour.

[0126] Step S222: The maximum load of the cell of the first network standard within the preset target time period is used as the first load, and the maximum load of the cell of the second network standard is used as the second load.

[0127] The preset target time period can be flexibly set based on actual needs, and the preset target time period is greater than the load acquisition cycle. For example, assuming the load of the first network standard cell and the load of the second network standard cell are acquired every hour, the maximum load of the first network standard cell and the load of the second network standard cell acquired within 24 hours can be used as the first load, and the maximum load of the second network standard cell can be used as the second load. In this way, the maximum loads of the first network standard cell and the second network standard cell can be acquired, so that the resources allocated to the first network standard cell and the second network standard cell meet their maximum service needs.

[0128] In the second manner, step S22 includes: obtaining the load of the first network standard cell at a preset first time to obtain a first load; obtaining the load of the second network standard cell at a preset second time to obtain a second load.

[0129] In the second method, considering that the times when the load of each network standard cell is high are usually concentrated at fixed times, such as 5:00 PM, 8:00 PM, 9:00 PM, 10:00 PM, 11:00 PM, 11:00 PM, 12:00 PM, and 12:00 PM, the times when the load of the first network standard cell is high can be directly set as the preset first time, and the times when the load of the second network standard cell is high can be set as the preset second time. Then, the load of the first network standard cell at the preset first time is obtained as the first load, and the load of the second network standard cell at the preset second time is obtained as the second load. For example, the preset first time can be set to 5:00 PM and the preset second time can be set to 11:00 PM.

[0130] In the spectrum sharing method provided in an embodiment of the present invention, the load of the first network standard cell and the load of the second network standard cell are periodically obtained, and the maximum load of the first network standard cell within a preset target time period is used as the first load, and the maximum load of the second network standard cell is used as the second load, so that the resources allocated to the first network standard cell and the second network standard cell meet their maximum business needs; or, the load of the first network standard cell at a preset first time is obtained to obtain the first load, and the load of the second network standard cell at a preset second time is obtained to obtain the second load, thereby reducing the power consumption of the acquired loads.

[0131] Based on the foregoing embodiments, a fifth embodiment of the spectrum sharing method of the present invention is provided. In this embodiment of the present invention, step S23 includes: determining a ratio of spectrum resources of the first network standard cell to spectrum resources of the second network standard cell based on the ratio of the first load to the second load, the maximum spectrum efficiency of the first network standard cell, and the maximum spectrum efficiency of the second network standard cell, to obtain a target ratio.

[0132] It should be noted that the maximum spectrum efficiency is the theoretical maximum spectrum efficiency, that is, the spectrum efficiency when the spectrum is fully loaded.

[0133] Considering the differences between different network standards, the corresponding maximum spectrum efficiencies are different. That is, under the same bandwidth spectrum resources, the maximum amount of data that can be transmitted is different. For example, assuming a spectrum resource with a bandwidth of 20 MHz, the number of available PRBs for NR FDD is 106, and the number of available PRBs for LTE FDD is 100. Due to the difference in the number of PRBs, the maximum spectrum efficiency of NR FDD increases by 6% compared to the maximum spectrum efficiency of LTE FDD, that is, (106-100) / 100. In addition, the reference signal overhead of NR FDD is approximately 9% less than that of LTE FDD. Therefore, the maximum spectrum efficiency of NR FDD increases by 15% compared to the maximum spectrum efficiency of LTE FDD. That is, under the same bandwidth, the net amount of data transmitted based on NR FDD is greater than the net amount of data transmitted based on LTE FDD. Therefore, in this embodiment of the present invention, based on the ratio of the first load to the second load, the maximum spectrum efficiency of the cell of the first network standard, and the maximum spectrum efficiency of the cell of the second network standard, the ratio of the spectrum resources of the cell of the first network standard to the spectrum resources of the cell of the second network standard is determined to obtain a target ratio.

[0134] The relationship among the target ratio, the first load, the second load, the maximum spectrum efficiency of the cell of the first network standard, and the maximum spectrum efficiency of the cell of the second network standard may be as follows:

[0135] Target ratio = (first load / second load) * (maximum spectrum efficiency of the second network standard cell / maximum spectrum efficiency of the first network standard cell)

[0136] In the spectrum sharing method provided by an embodiment of the present invention, based on the ratio of the first load and the second load, the maximum spectrum efficiency of the first network standard cell and the maximum spectrum efficiency of the second network standard cell, the ratio of the spectrum resources of the first network standard cell and the spectrum resources of the second network standard cell is determined to obtain a target ratio. That is, when allocating spectrum resources to the first network standard cell and the second network standard cell, not only the loads of the first network standard cell and the second network standard cell are referred to, but also the maximum spectrum efficiency of the first network standard cell and the second network standard cell is referred to, so that the spectrum resources allocated to the first network standard cell and the second network standard cell are more in line with their business needs.

[0137] Based on the above embodiments, a sixth embodiment of the spectrum sharing method of the present invention is provided. In this embodiment of the present invention, step S24 includes:

[0138] Step S241: Based on the target ratio and the shared spectrum resources, determine the first spectrum resources of the first network standard cell and the second spectrum resources of the second network standard cell.

[0139] The ratio of the first matching resource to the second spectrum resource is a target ratio, and the sum of the first spectrum resource and the second spectrum resource is a shared spectrum resource.

[0140] Step S242: Determine the priorities of the first network standard cell and the second network standard cell.

[0141] The method of determining the priority of the first network standard cell and the second network standard cell can be flexibly set according to actual needs.

[0142] In some implementations, the priorities of the first network standard cell and the second network standard cell may be pre-set and stored. For example, the priority of the first network standard cell may be set higher than the priority of the second network standard cell, or the priority of the first network standard cell may be set lower than the priority of the second network standard cell.

[0143] In some embodiments, the priority of the first network standard and the second network standard can be determined based on the release time. For example, considering that in the early stages of infrastructure construction of a network standard released later, its basic equipment is not complete and there are few users, while at this time, the infrastructure of the network standard released earlier is mature and there are many users, the priority of the network standard released earlier can be set higher than the priority of the network standard released later, so as to give priority to meeting the service needs of the network standard released earlier and enable more users to obtain a good experience. For example, for NR FDD and LTE FDD, the priority of LTE FDD can be set higher than the priority of NR FDD. In this way, in the early stages of NR FDD construction, there are few NR FDD users and many LTE FDD users, so the service needs of LTE FDD are given priority, so that more users can obtain a good experience. For another example, considering that the communication quality of the network standard released later is generally better and can provide users with a better experience, the priority of the network standard released later can be set higher than the priority of the network standard released earlier.

[0144] In some implementations, the priority of the first network standard and the second network standard can be determined based on the time of publication and the degree of construction maturity. When the construction of the network standard with a later publication time is mature, the priority of the network standard with a later publication time is higher than that of the network standard with an earlier publication time. In the early stages of construction of the network standard with a later publication time, the priority of the network standard with a later publication time is lower than that of the network standard with an earlier publication time. The degree of construction maturity of a network standard can be determined based on the total number of users of the network standard, or can be set by network personnel.

[0145] Step S243: If the priority of the cell of the first network standard is higher than the priority of the cell of the second network standard, determine a first initial spectrum resource and a second initial spectrum resource based on the first spectrum resource and the second spectrum resource.

[0146] The first initial spectrum resource is greater than or equal to the first spectrum resource; the second initial spectrum resource is greater than or equal to 0 and less than or equal to the second spectrum resource. In one example, to avoid wasting shared spectrum resources, the sum of the first initial spectrum resource and the second initial spectrum resource is equal to the shared spectrum resource. Specifically, this setting can be flexibly adjusted based on actual needs.

[0147] In an embodiment of the present invention, if the priority of the first network standard cell is higher than that of the second network standard cell, the initial spectrum resources of the first network standard cell are set to be greater than the first matching resources, thereby preferentially meeting the service requirements of the first network standard cell.

[0148] Step S244: setting the spectrum resources of the cell of the first network standard as the first initial spectrum resources, and setting the spectrum resources of the cell of the second network standard as the second initial spectrum resources.

[0149] After determining the first initial spectrum resources and the second initial spectrum resources, the spectrum resources of the first network standard cell are set as the first initial spectrum resources, and the spectrum resources of the second network standard cell are set as the second initial spectrum resources.

[0150] Step S245: Based on the load of the second network standard cell, increase the spectrum resources of the second network standard cell and reduce the spectrum resources of the first network standard cell until the spectrum resources of the second network standard cell reach the second spectrum resources.

[0151] The load of the second network standard cell is a parameter representing the load condition of the second network standard cell, for example, it may be throughput, number of terminal accesses, etc.

[0152] In an embodiment of the present invention, after the spectrum resources of the first network standard cell are set to the first initial spectrum resources and the spectrum resources of the second network standard cell are set to the second initial spectrum resources, based on the load of the second network standard cell, the spectrum resources of the second network standard cell are increased and the spectrum resources of the first network standard cell are reduced until the spectrum resources of the second network standard cell reach the second spectrum resources.

[0153] Among them, when the spectrum resources of the second network standard cell are increased, the spectrum resources of the first network standard cell can be reduced simultaneously, thereby avoiding system interference between the first network standard cell and the second network standard cell during the spectrum resource adjustment process to a large extent.

[0154] In the process of increasing the spectrum resources of the second network standard cell and reducing the spectrum resources of the first network standard cell, the sum of the spectrum resources of the second network standard cell and the spectrum resources of the first network standard cell can be maintained as shared spectrum resources.

[0155] It should be noted that the specific implementation of step S245 can be flexibly set according to actual needs. For example, the implementation of step S245 includes but is not limited to the following three methods.

[0156] In the first method, step S245 may include: based on the throughput of the second network standard cell and the mapping relationship between the preset throughput and spectrum resources, increasing the spectrum resources of the second network standard cell and reducing the spectrum resources of the first network standard cell until the spectrum resources of the second network standard cell reach the second spectrum resources.

[0157] A mapping relationship between throughput and spectrum resources can be pre-set, where a greater throughput corresponds to a greater spectrum resource. Then, based on the throughput of the second network standard cell, the corresponding spectrum resource is searched from the mapping relationship between throughput and spectrum resources. The spectrum resource of the second network standard cell is added to the searched spectrum resource, and the spectrum resource of the first network standard cell is reduced until the spectrum resource of the second network standard cell reaches the second spectrum resource.

[0158] In the second method, step S245 may include: based on the number of terminal accesses to the second network standard cell and the mapping relationship between the preset access number and spectrum resources, increasing the spectrum resources of the second network standard cell and reducing the spectrum resources of the first network standard cell until the spectrum resources of the second network standard cell reach the second spectrum resources.

[0159] The number of terminal accesses is the number of terminals accessing the second network standard cell.

[0160] A mapping relationship between the number of access points and spectrum resources can be preset, where a larger number of access points corresponds to larger spectrum resources. Then, based on the number of terminal access points in the second network standard cell, the corresponding spectrum resources are searched from the preset mapping relationship between the number of access points and spectrum resources. The spectrum resources of the second network standard cell are increased to the searched spectrum resources, and the spectrum resources of the first network standard cell are reduced until the spectrum resources of the second network standard cell reach the second spectrum resources.

[0161] In the third manner, when it is monitored that the terminal accesses the second network standard cell, the spectrum resources of the second network standard cell are increased to the second spectrum resources, and the spectrum resources of the first network standard cell are reduced to the first spectrum resources.

[0162] When a terminal accesses the second network standard cell, the spectrum resources of the second network standard cell are increased from the second initial spectrum resources to the second spectrum resources, and the spectrum resources of the first network standard cell are reduced from the first initial spectrum resources to the first spectrum resources.

[0163] In some embodiments, if the priority of the first network standard cell is lower than the priority of the second network standard cell, a first initial spectrum resource and a second initial spectrum resource may be determined based on the first spectrum resource and the second spectrum resource, wherein the first initial spectrum resource is greater than or equal to 0 and less than the first spectrum resource; the second initial spectrum resource is greater than the second spectrum resource; the spectrum resource of the first network standard cell is set as the first initial spectrum resource, and the spectrum resource of the second network standard cell is set as the second initial spectrum resource; based on the load of the first network standard cell, the spectrum resource of the first network standard cell is increased, and the spectrum resource of the second network standard cell is decreased, until the spectrum resource of the first network standard cell reaches the first spectrum resource. For the implementation method of increasing the spectrum resource of the first network standard cell and decreasing the spectrum resource of the second network standard cell based on the load of the first network standard cell until the spectrum resource of the first network standard cell reaches the first spectrum resource, refer to the aforementioned step S245.

[0164] In the spectrum sharing method provided by an embodiment of the present invention, a first spectrum resource of a first network standard cell and a second spectrum resource of a second network standard cell are first determined based on a target ratio and shared spectrum resources. Then, the priorities of the first network standard cell and the second network standard cell are determined. If the priority of the first network standard cell is higher than that of the second network standard cell, a first initial spectrum resource and a second initial spectrum resource are determined based on the first spectrum resource and the second spectrum resource, wherein the first initial spectrum resource is greater than or equal to the first spectrum resource and the second initial spectrum resource is greater than or equal to 0 and less than or equal to the second spectrum resource. The spectrum resource of the first network standard cell is set as the first initial spectrum resource, and the spectrum resource of the second network standard cell is set as the second initial spectrum resource. Based on the load of the second network standard cell, the spectrum resource of the second network standard cell is increased, and the spectrum resource of the first network standard cell is decreased until the spectrum resource of the second network standard cell reaches the second spectrum resource. By setting the spectrum resource of the higher-priority network standard cell higher and then adjusting the spectrum resource based on the load of the lower-priority network standard cell, the service needs of the higher-priority network standard cell are guaranteed while the service needs of the lower-priority network standard cell are guaranteed.
