[0002] Spectrum resources are important strategic resources in the information economy era and an important carrier for the deep integration of information and industrialization. With the development of mobile Internet technology, the amount of wireless data has shown explosive growth, triggering a sharp increase in demand for spectrum resources.
[0003] At present, in different deployment stages of 4G and 5G NR wireless networks, the main method is to statically configure 45G spectrum according to the different network load conditions between the two standards (two network types) to improve spectrum utilization. Taking China Mobile's 2.6G frequency band (electromagnetic wave frequency range) (2515-2675MHz) as an example, Figure 1 As shown in the figure, in the early stage of NR wireless network deployment, the LTE wireless network load continues to grow, and the LTE wireless network occupies more spectrum; in the mature deployment period of NR wireless network, the LTE wireless network load continues to decline, and the NR wireless network occupies more spectrum.
[0004] The aforementioned technical solutions for sharing and flexibly configuring 4G and 5G frequencies typically require manual analysis, relying primarily on optimization engineers to develop 4G and 5G frequency configuration plans based on load assessments of the 4G and 5G networks over a period of time. Different statistical methods significantly influence the evaluation results, and actual results vary significantly due to various subjective factors.
[0005] However, the above-mentioned solution relies on optimization engineers to manually analyze the 4G and 5G load assessment results to complete the spectrum resource sharing configuration.

[0054] Example 1
[0055] See also Figure 1 , which shows a flowchart of the steps of the dynamic spectrum sharing method according to an embodiment of the present invention. It is understood that the flowchart in this embodiment of the method is not intended to limit the order in which the steps are executed. The following exemplary description is given using a computer device as the execution subject, as follows:
[0056] like Figure 1As shown, the dynamic spectrum sharing method may include steps S100 to S106, wherein:
[0057] Step S100: Obtain a first load status of an LTE wireless network of an LTE cell and obtain a second load status of an NR wireless network of an NR cell.
[0058] Among them, the performance data of the LTE wireless network (4G standard network) and the NR wireless network (5G standard network) are collected respectively by the base station, that is, the first load state and the second load state. In this embodiment, combined with the different deployment stages of the LTE wireless network and the NR wireless network, the system spectrum can be dynamically shared between the LTE wireless network and the NR wireless network. It can be understood that when the NR wireless network load is lower than the threshold value, the NR wireless network can share spectrum resources with the LTE cell. When the LTE wireless network load is lower than the threshold value, the LTE wireless network can share spectrum resources with the NR cell. That is, dynamic sharing of the system spectrum is achieved through carrier-level spectrum sharing. The 4G network and the 5G network have no overlapping spectrum at the same time, and the spectrum configuration is the same within a certain period. Spectrum sharing is achieved by adjusting the bandwidth of the 4G network and the 5G network within a certain period of time. The shared carrier is only used by one standard at the same time.
[0059] For example, by collecting performance data of LTE wireless networks and NR wireless networks, reasonable threshold decision threshold values are planned based on PRB (Physical Resource Block) utilization and the number of RRC (Radio Resource Control) connected users, so that a reasonable dynamic spectrum sharing solution can be implemented.
[0060] Step S102: Determine a first spectrum sharing state of the LTE wireless network and a second spectrum sharing state of the NR wireless network based on the first load state and the second load state, respectively. In an exemplary embodiment, the first load state includes: a utilization rate of LTE wireless network physical resource blocks of the LTE cell and the number of connected users of the LTE wireless network; the second load state includes a utilization rate of NR wireless network physical resource blocks of the NR cell and available spectrum parameters of the NR wireless network.

[0062] In this embodiment, the spectrum sharing state of the LTE wireless network is determined by the eNodeB (Evolved Node B, i.e., an evolved Node B, a base station in an LTE wireless network, i.e., a base station in a 4G wireless network) based on the LTE wireless network PRB utilization of the cell reported by the shared cell and the collaborative cell and the number of LTE wireless network RRC connected users, according to the spectrum sharing state logic of the LTE wireless network. The first spectrum sharing state of the LTE wireless network includes the LTE wireless network spectrum sharing out state, the LTE wireless network spectrum sharing in state, and the LTE wireless network spectrum not shared state, wherein the LTE wireless network spectrum sharing out state includes the LTE wireless network spectrum sharing out state with extremely low load and the LTE wireless network spectrum sharing out state with low load. The spectrum sharing state of the NR wireless network is determined by the gNodeB (a base station in an NR wireless network, i.e., a base station in a 5G wireless network) based on the NR wireless network PRB utilization of the cell reported by the cell, according to the NR wireless network spectrum sharing state logic. The second spectrum sharing state of the NR wireless network includes the NR wireless network spectrum sharing out state, the NR wireless network spectrum sharing in state, or the NR wireless network spectrum not shared state. Among them, the NR wireless network spectrum sharing out state includes: NR wireless network spectrum sharing out state, and the load is extremely low, NR wireless network spectrum sharing out state, and the load is low.
[0063] In an exemplary embodiment, according to the four types of the first spectrum sharing state of the LTE wireless network, each corresponds to a decision logic, and the corresponding first spectrum sharing state of the LTE wireless network can also be obtained for the four decision logics, where:
[0064] Decision logic 1: If the utilization rate of the uplink physical resource blocks of the LTE wireless network (LTE wireless network uplink PRB utilization) and the utilization rate of the downlink physical resource blocks of the LTE wireless network (LTE wireless network downlink PRB utilization) are both not greater than a first number of times the difference between a preconfigured LTE wireless network utilization threshold (LTE wireless network PRB utilization threshold) and a preconfigured LTE wireless network utilization bias parameter (LTE wireless network PRB utilization bias), and the number of connected users of the LTE wireless network is not greater than a first number of times the difference between a preconfigured connected user number threshold and a preconfigured connected user number bias parameter, then the first spectrum sharing state of the LTE wireless network is determined to be an LTE wireless network spectrum sharing-out state, and the first load state of the LTE wireless network is determined to be a first type of low-value load state, wherein the first number of times is less than 1. The first number of times can be set to 0.5 times.

[0070] Decision logic 2: If the utilization rate of the uplink physical resource block of the LTE wireless network and the utilization rate of the downlink physical resource block of the LTE wireless network are both not greater than the difference between the preconfigured LTE wireless network utilization threshold and the preconfigured LTE wireless network utilization bias parameter, the number of connected users of the LTE wireless network is not greater than the difference between the preconfigured connected user number threshold and the preconfigured connected user number bias parameter, and the utilization rate of the uplink physical resource block of the LTE wireless network is not greater than the first number of times the difference between the preconfigured LTE wireless network utilization threshold and the preconfigured LTE wireless network utilization bias parameter, the utilization rate of the down ... In any one of the following cases, that is, the utilization rate is not greater than the first number of times the difference between the preconfigured LTE wireless network utilization threshold and the preconfigured LTE wireless network utilization bias parameter, and the number of connected users of the LTE wireless network is not greater than the first number of times the difference between the preconfigured connected user number threshold and the preconfigured connected user number bias parameter, the first spectrum sharing state of the LTE wireless network is judged to be the LTE wireless network spectrum sharing out state, and the first load state of the LTE wireless network is the second type of low-value load state, wherein the network load corresponding to the second type of low-value load state is greater than the network load corresponding to the first type of low-value load state, and the first number of times is less than 1.
[0071] In this embodiment, the following conditions 1 to 3 must be met simultaneously:

[0075] And the following conditions 4 to 6 are not met at the same time:
[0076] Condition 4: LTE wireless network uplink PRB utilization ≤ 0.5x (LTE wireless network PRB utilization threshold – LTE wireless network PRB utilization offset);
[0077] Condition 5: LTE wireless network downlink PRB utilization ≤ 0.5x (LTE wireless network PRB utilization threshold – LTE wireless network PRB utilization offset);
[0078] Condition 6: The number of LTE wireless network RRC connected users ≤ 0.5x (LTE wireless network RRC connected user number threshold – LTE wireless network RRC connected user number offset);
[0079] When conditions 1 to 3 of the second decision logic are met at the same time, but conditions 4 to 6 are not met at the same time, it is determined that the first spectrum sharing state of the LTE wireless network is the LTE wireless network spectrum sharing out state, and the first load state of the LTE wireless network is the second type of low-value load state, which can be understood as the current LTE wireless network load is low.
[0080] Decision logic three: If the utilization rate of the uplink physical resource blocks of the LTE wireless network and the utilization rate of the downlink physical resource blocks of the LTE wireless network are both greater than the sum of the preconfigured LTE wireless network utilization threshold and the preconfigured LTE wireless network utilization bias parameter, and the number of connected users of the LTE wireless network is greater than the sum of the preconfigured connected user number threshold and the preconfigured connected user number bias parameter, then the first spectrum sharing state of the LTE wireless network is judged to be the LTE wireless network spectrum sharing entry state.
[0081] In this embodiment, the following conditions 1 to 3 must be met simultaneously:
[0082] Condition 1: LTE wireless network uplink PRB utilization > LTE wireless network PRB utilization threshold + LTE wireless network PRB utilization offset;
[0083] Condition 2: LTE wireless network downlink PRB utilization > LTE wireless network PRB utilization threshold + LTE wireless network PRB utilization offset;
[0084] Condition 3: Number of LTE wireless network RRC connected users > LTE wireless network RRC connected user number threshold + LTE wireless network RRC connected user number offset;
[0085] When conditions 1 to 3 of the decision logic 3 are simultaneously satisfied, it is determined that the first spectrum sharing state of the LTE wireless network is the LTE wireless network spectrum sharing entering state.
[0086] Decision logic 4: If any of the above decision logics 1 to 3 are not satisfied, it is determined that the first spectrum sharing state of the LTE wireless network is that the LTE wireless network spectrum is not shared.

[0088] In an exemplary embodiment, according to the four types of the second spectrum sharing state of the NR wireless network, each corresponds to a decision logic, and the corresponding second spectrum sharing state of the NR wireless network can be obtained for the four decision logics, where:
[0089] Decision logic 1: If the available spectrum parameter of the NR wireless network is the first spectrum parameter or the second spectrum parameter, the second spectrum parameter is greater than the first spectrum parameter, and the utilization rate of the uplink physical resource block of the NR wireless network and the utilization rate of the downlink physical resource block of the NR wireless network are both not greater than the second number of times the difference between the pre-configured NR wireless network utilization threshold and the pre-configured NR wireless network utilization bias parameter, then the second spectrum sharing state of the NR wireless network is judged to be the NR wireless network spectrum sharing out state, and the second load state of the NR wireless network is the third type low-value load state, wherein the second number of times is set according to the bandwidth of the NR wireless network.
[0090] In this embodiment, when the available spectrum of NR is 60 MHz, spectrum sharing is not possible.
[0091] When the NR available spectrum is 80 MHz (first spectrum parameter) or 100 MHz (second spectrum parameter), the following conditions must be met simultaneously:
[0092] Condition 1: NR wireless network downlink PRB utilization ≤ bx(NR wireless network PRB utilization threshold – NR wireless network PRB utilization offset);
[0093] Condition 2: NR wireless network uplink PRB utilization ≤ bx(NR wireless network PRB utilization threshold – NR wireless network PRB utilization offset).
[0094] When conditions 1 to 2 of decision logic 1 are met at the same time, it is determined that the second spectrum sharing state of the NR wireless network is the NR wireless network spectrum sharing out state, and the second load state of the NR wireless network is the third type of low-value load state, which can be understood as the current NR wireless network load is extremely low.
[0095] Decision Logic 2: If the available spectrum parameter of the NR wireless network is the first spectrum parameter or the second spectrum parameter, the second spectrum parameter is greater than the first spectrum parameter, the utilization rate of the uplink physical resource blocks of the NR wireless network and the utilization rate of the downlink physical resource blocks of the NR wireless network are both not greater than the difference between the pre-configured NR wireless network utilization threshold and the pre-configured NR wireless network utilization bias parameter, and the utilization rate of the uplink physical resource blocks of the NR wireless network and the utilization rate of the downlink physical resource blocks of the NR wireless network are both greater than the second multiple of the difference between the pre-configured NR wireless network utilization threshold and the pre-configured NR wireless network utilization bias parameter, then it is determined that the second spectrum sharing state of the NR wireless network is the NR wireless network spectrum sharing out state, and the second load state of the NR wireless network is the fourth type of low-value load state, where the network load amount corresponding to the fourth type of low-value load state is greater than the network load amount corresponding to the third type of low-value load state, and the second multiple is set according to the bandwidth of the NR wireless network.
[0096] In this embodiment, when the NR available spectrum is sixty MHz, spectrum sharing out is not possible.
[0097] When the NR available spectrum is 80 MHz (the first spectrum parameter) or 100 MHz (the second spectrum parameter), the following conditions need to be satisfied simultaneously:
[0098] Condition 1: b x (NR wireless network PRB utilization threshold – NR wireless network PRB utilization bias) < NR wireless network downlink PRB utilization ≤ (NR wireless network PRB utilization threshold – NR wireless network PRB utilization bias)
[0099] Condition 2: b x (NR wireless network PRB utilization threshold – NR wireless network PRB utilization bias) < NR wireless network uplink PRB utilization ≤ (NR wireless network PRB utilization threshold – NR wireless network PRB utilization bias).
[0100] When Conditions 1 to 2 of Decision Logic 2 are satisfied simultaneously, it is determined that the second spectrum sharing state of the NR wireless network is the NR wireless network spectrum sharing out state, and the second load state of the NR wireless network is the fourth type of low-value load state, which can be understood as the current NR wireless network load being extremely low.
[0101] Decision logic three: If the available spectrum parameter of the NR wireless network is the first spectrum parameter or the third spectrum parameter, and the third spectrum parameter is less than the first spectrum parameter, and the utilization of the uplink physical resource block of the NR wireless network is greater than the sum of the preconfigured NR wireless network utilization threshold and the preconfigured NR wireless network utilization bias parameter, and the utilization of the downlink physical resource block of the NR wireless network is greater than any one of the sum of the preconfigured NR wireless network utilization threshold and the preconfigured NR wireless network utilization bias parameter, then the second spectrum sharing state of the NR wireless network is judged to be the NR wireless network spectrum sharing entry state.
[0102] In this embodiment, when the NR available spectrum is 100 MHz, spectrum sharing is not possible.
[0103] When the NR available spectrum is 60 MHz (third spectrum parameter) or 80 MHz (first spectrum parameter), one of the following conditions must be met:
[0104] Condition 1: NR wireless network downlink PRB utilization > (NR wireless network PRB utilization threshold + NR wireless network PRB utilization offset);
[0105] Condition 2: NR wireless network uplink PRB utilization > (NR wireless network PRB utilization threshold + NR wireless network PRB utilization offset).
[0106] When any one of conditions 1 and 2 of decision logic three is met, it is determined that the second spectrum sharing state of the NR wireless network is the NR wireless network spectrum sharing entry state.
[0107] Decision logic 4: If any of the above decision logics 1-3 are not satisfied, the second spectrum sharing state of the NR wireless network is determined to be NR wireless network spectrum unshared. In the above, NR wireless network uplink PRB utilization = number of PRBs used in the cell uplink / number of available RBs (resource blocks) in the cell; NR wireless network downlink PRB utilization = number of PRBs used in the cell downlink / number of available RBs in the cell. b is automatically calculated based on BWP0 / BWP1, where BWP represents a sub-bandwidth of the total cell bandwidth.
[0108] Step S104: performing spectrum sharing decision according to the first spectrum sharing state, the second spectrum sharing state, the preconfigured dynamic sharing decision configuration parameters and the preconfigured spectrum sharing priority parameters to obtain a spectrum sharing decision conclusion.
[0109] In this embodiment, a dynamic spectrum sharing decision can be made for the target LTE wireless network and the NR wireless network based on the performance data of the LTE cell and the NR cell, and dynamic spectrum sharing can be executed.
[0110] To achieve dynamic spectrum sharing, the method also requires using PRB utilization, the number of 4G RRC connections, and the number of 5G users as characteristic variables. Through practical evaluation of the comprehensive network performance, a dynamic spectrum sharing status decision threshold is obtained. According to the decision threshold, actual parameter configuration recommendations are obtained (as shown in Table 1 below). Based on the configuration recommendations, the dynamic spectrum sharing configuration parameters for the LTE wireless network and the NR wireless network are output:
[0111]
[0112]
[0113] Table 1 Parameters for determining the dynamic spectrum sharing status of LTE and NR wireless networks
[0114] In an exemplary embodiment, after the LTE network and the NR network determine the spectrum sharing status in combination with the system priority, the spectrum sharing decision is made according to the set spectrum sharing priority of the LTE network and the NR network. The spectrum sharing priority of the LTE network and the NR network includes three priority settings: (1) the LTE network and the NR network are set to be fair; (2) the LTE network takes precedence over the NR network; (3) the NR network takes precedence over the LTE network. The following takes the spectrum sharing priority setting of the LTE network and the NR network as an example to illustrate the operation of making a spectrum sharing decision according to the first spectrum sharing status, the second spectrum sharing status, the pre-configured dynamic sharing decision configuration parameters and the pre-configured spectrum sharing priority parameters to obtain the spectrum sharing decision conclusion, as follows:
[0115] (1) The LTE wireless network and the NR wireless network are set to be fair. The comprehensive judgment is based on the spectrum sharing status of the LTE wireless network and the spectrum sharing status of the NR wireless network, without any bias towards the LTE wireless network or the NR wireless network.
[0116] If the preconfigured spectrum sharing priority parameter is used to indicate that the LTE wireless network and the NR wireless network are fair, the first spectrum sharing state is the LTE wireless network spectrum sharing out state, and the second spectrum sharing state is the NR wireless network spectrum sharing in state, then a spectrum sharing decision conclusion is obtained indicating that the LTE wireless network transfers the shared spectrum to the NR wireless network;
[0117] If the preconfigured spectrum sharing priority parameter is used to indicate that the LTE wireless network and the NR wireless network are fair, the first spectrum sharing state is the spectrum sharing entry state of the LTE wireless network, and the second spectrum sharing state is the spectrum sharing exit state of the NR wireless network, then a spectrum sharing decision conclusion is obtained indicating that the NR wireless network transfers the shared spectrum to the LTE wireless network.
[0118] To understand the specific spectrum sharing decisions when fairness is set between the LTE wireless network and the NR wireless network, see Table 2 below:
[0119]
[0120] Table 2 Fair spectrum sharing decisions for LTE and NR wireless networks
[0121] In this embodiment, shared spectrum a: if the NR cell bandwidth is configured to 100 MHz, LTE transfers all shared spectrum to NR, with a maximum of 40 MHz of spectrum; if the NR cell bandwidth is configured to 80 MHz, LTE transfers 20 MHz of spectrum to NR.
[0122] Shared spectrum b: If the NR cell bandwidth is configured to 100 MHz, NR will transfer all shared spectrum to LTE, with a maximum of 40 MHz of spectrum. If the NR cell bandwidth is configured to 80 MHz, NR will transfer 20 MHz of spectrum to LTE.
[0123] (2) LTE network takes precedence over NR network. When the spectrum sharing status of LTE wireless network is "LTE spectrum sharing in", spectrum is provided to LTE wireless network first.
[0124] If the preconfigured spectrum sharing priority parameter is used to indicate that the LTE wireless network takes precedence over the NR wireless network, the first spectrum sharing state is the spectrum sharing out state of the LTE wireless network, and the second spectrum sharing state is the spectrum sharing in state of the NR wireless network, then a spectrum sharing decision conclusion is obtained indicating that the LTE wireless network transfers the shared spectrum to the NR wireless network;
[0125] If the preconfigured spectrum sharing priority parameter is used to indicate that the LTE wireless network takes precedence over the NR wireless network, and the first spectrum sharing state is the spectrum sharing entry state of the LTE wireless network, then a spectrum sharing decision conclusion is obtained indicating that the NR wireless network transfers the shared spectrum to the LTE wireless network.
[0126] To understand the specific spectrum sharing decisions when LTE networks take precedence over NR networks, see the following:
[0127] Table 3:
[0128]
[0129] Table 3 LTE wireless network priority spectrum sharing decision
[0130] In this embodiment, shared spectrum a: if the NR cell bandwidth is configured to 100 MHz, LTE transfers all shared spectrum to NR, with a maximum of 40 MHz of spectrum; if the NR cell bandwidth is configured to 80 MHz, LTE transfers 20 MHz of spectrum to NR.
[0131] Shared spectrum b: If the NR cell bandwidth is configured to 100 MHz, NR will transfer all shared spectrum to LTE, with a maximum of 40 MHz of spectrum. If the NR cell bandwidth is configured to 80 MHz, NR will transfer 20 MHz of spectrum to LTE.
[0132] (3) NR network takes precedence over LTE network. When the spectrum sharing status of NR wireless network is "NR spectrum sharing in", spectrum is provided to NR wireless network first.
[0133] If the preconfigured spectrum sharing priority parameter is used to indicate that the NR wireless network takes precedence over the LTE wireless network, the first spectrum sharing state is any one of the spectrum sharing out state of the LTE wireless network, the spectrum sharing in state of the LTE wireless network, and the spectrum non-sharing state of the LTE wireless network, and the second spectrum sharing state is the spectrum sharing in state of the NR wireless network, then a spectrum sharing decision conclusion is obtained indicating that the LTE wireless network transfers the shared spectrum to the NR wireless network;
[0134] If the preconfigured spectrum sharing priority parameter is used to indicate that the NR wireless network takes precedence over the LTE wireless network, the first spectrum sharing state is the spectrum sharing entry state of the LTE wireless network, and the second spectrum sharing state is the spectrum sharing exit state of the NR wireless network, then a spectrum sharing decision conclusion is obtained indicating that the NR wireless network transfers the shared spectrum to the LTE wireless network.
[0135] To understand the specific spectrum sharing decisions when NR wireless networks take precedence over LTE wireless networks, see Table 4 below:
[0136]
[0137] Table 4 Spectrum sharing decision for NR wireless network priority
[0138] In this embodiment, shared spectrum a: if the NR cell bandwidth is configured to 100 MHz, LTE transfers all shared spectrum to NR, with a maximum of 40 MHz of spectrum; if the NR cell bandwidth is configured to 80 MHz, LTE transfers 20 MHz of spectrum to NR.
[0139] Shared spectrum b: If the NR cell bandwidth is configured to 100 MHz, NR will transfer all shared spectrum to LTE, with a maximum of 40 MHz of spectrum. If the NR cell bandwidth is configured to 80 MHz, NR will transfer 20 MHz of spectrum to LTE.
[0140] Step S106: Execute the spectrum sharing decision conclusion to implement dynamic spectrum sharing between the LTE wireless network and the NR wireless network.
[0141] Among them, after determining the spectrum sharing judgment conclusion, the spectrum sharing conclusion is executed to realize spectrum sharing, so as to better adapt to and meet the changes in business volume demand.
[0142] In an exemplary embodiment, after determining the first spectrum sharing state of the LTE wireless network and the second spectrum sharing state of the NR wireless network, the method further includes: determining whether the mutual switching protection time between the LTE wireless network and the NR wireless network exceeds a preset protection time threshold; if the mutual switching protection time between the LTE wireless network and the NR wireless network exceeds the preset protection time threshold, a spectrum sharing determination is made.
[0143] In an exemplary embodiment, after executing the spectrum sharing decision conclusion, the method further includes: after executing dynamic spectrum sharing, obtaining a new first load state of the LTE wireless network of the LTE cell and obtaining a new second load state of the NR wireless network of the NR cell; performing a spectrum sharing decision based on the new first load state, the new second load state, the preconfigured dynamic sharing decision configuration parameters and the preconfigured spectrum sharing priority parameters to obtain a new spectrum sharing decision conclusion; judging whether the new spectrum sharing decision conclusion meets the spectrum sharing requirements; if the new spectrum sharing decision conclusion does not meet the spectrum sharing requirements, adjusting the new spectrum sharing decision conclusion. In this embodiment, after executing the spectrum sharing decision conclusion, it is also possible to combine performance data collection to evaluate the spectrum sharing effect and reasonably determine whether to perform spectrum sharing fallback or sharing scheme change; it is possible to complete dynamic spectrum sharing for the LTE wireless network and the NR wireless network card in a timely and accurate manner, achieve effective adjustment of the capacity of the LTE wireless network and the NR wireless network, and maximize the utilization of spectrum resources.
[0144] Taking the 160M spectrum of the D-band (2570M~2620M (2.6GHz) spectrum) shared by China Mobile's 4G and 5G as an example, by dynamically monitoring the 4G and 5G network loads and based on changes in business demand, dynamic sharing of 4G and 5G spectrum resources is achieved to maximize spectrum utilization, ensuring that the 5G NR network can use a large bandwidth of 100M, while also ensuring that the 4G network obtains more carrier capacity.
[0145] The embodiments of the present invention have at least the following technical effects:
[0146] (1) The entire execution process of the dynamic spectrum sharing method is based on objective data, which avoids the influence of subjective factors on the spectrum sharing results and effectively improves the accuracy and rationality of the dynamic sharing solution.
[0147] (2) The spectrum sharing decision rule based on network load proposed in this invention can take advantage of the traffic differences and tidal effects between different standards and frequency bands, dynamically adjust the air interface resources allocated to 4G and 5G NR according to real-time changes in business demand, and effectively improve spectrum utilization;
[0148] (3) The dynamic spectrum sharing method proposed in the present invention is very suitable for IT processing, realizing the automatic execution of dynamic spectrum sharing schemes for LTE wireless networks and NR wireless networks, and improving the timeliness of 4G and 5G dynamic spectrum sharing.
