[0023] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0024] With the rapid development of mobile communication technology, 5G networks have brought users unprecedented mobile communication experience with their advantages of high speed, low latency, large capacity and wide coverage. However, the current low-frequency spectrum resources are almost all occupied by 2G, 3G and 4G, especially 4G, which will coexist with 5G for a long time, making it impossible to use spectrum refarming methods to provide sufficient spectrum resources for 5G. Therefore, in order to alleviate the tension of spectrum resources, dynamic spectrum sharing technology is adopted, that is, by allowing different users or networks to share and use the same spectrum resources, efficient use of spectrum resources is achieved, thereby alleviating the tension of spectrum resources.

[0025] The embodiment of the present application provides a method for dynamic spectrum sharing of a 5G network, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method includes step S101, step S102 and step S103, wherein: Step S101: Obtain the number of 5G users, the number of 4G users and business needs, divide the spectrum based on the number of 5G users, the number of 4G users and business needs, and determine the 5G exclusive spectrum bandwidth, 4G exclusive spectrum bandwidth and shared spectrum bandwidth.

[0026] For the embodiments of the present application, in the early stage of 5G network deployment, since the number of 5G users is relatively small and 4G users still dominate, it is necessary to gradually promote the development of 5G network while ensuring the stable operation of 4G network. Therefore, dynamic spectrum division is performed according to the number of 5G users and the number of 4G users, and 5G exclusive spectrum bandwidth is divided for 5G users and 4G exclusive spectrum bandwidth is divided for 4G users respectively, so as to divide the shared spectrum bandwidth to adapt to the changes in spectrum demand in different time periods, different regions and different user scales, thereby balancing the development of 4G and 5G networks, and helping to ensure that 4G network users will not be greatly affected during the gradual expansion of 5G network. At the same time, 5G network can also obtain sufficient spectrum resources to support its rapid development.

[0027] Therefore, the number of 5G users, the number of 4G users and the business requirements are obtained. The number of 5G users and the number of 4G users can be obtained through the official channels of telecom operators. The business requirements specify multiple dimensions such as voice call requirements, data transmission requirements, and Internet application requirements corresponding to the 4G network and the 5G network respectively. Furthermore, spectrum division is performed based on the number of 5G users, the number of 4G users, and business requirements to determine the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth, and the shared spectrum bandwidth. There are many ways to divide the spectrum, and the embodiments of the present application are no longer limited. In one feasible method, a growth trend analysis is performed based on the number of 5G users and the number of 4G users to determine the change information of the number of 5G users and the change information of the number of 4G users; a spectrum demand analysis is performed based on the 5G business requirements and the 4G business requirements in the business requirements to determine the spectrum priorities corresponding to the spectrums of different frequency bands; spectrum division is performed based on the change information of the number of 5G users, the change information of the number of 4G users, and the spectrum priority to determine the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth, and the shared spectrum bandwidth.

[0028] Step S102: Monitor the first traffic information corresponding to the 5G exclusive spectrum bandwidth and the second traffic information corresponding to the 4G exclusive spectrum bandwidth in real time, make a spectrum sharing judgment based on the first traffic information and the second traffic information, and obtain a spectrum sharing judgment result.

[0029] For the embodiments of the present application, in an environment where 5G networks and 4G networks coexist, if spectrum sharing is always enabled, the overall network environment may cause network performance to degrade due to signal interference, resource competition and other issues. Therefore, in order to provide more stable and reliable communication services, spectrum sharing judgment is performed preferentially to more accurately match the traffic requirements of different networks, so that when any of the 5G exclusive spectrum bandwidth and the 4G exclusive spectrum bandwidth cannot meet the usage requirements, spectrum sharing can be enabled in a timely manner, thereby maximizing the utilization of spectrum resources and improving network capacity and flexibility.

[0030] Specifically, network monitoring software is used to collect the flow data corresponding to the 5G network and the 4G network in real time. The granularity of the data collection can be set according to actual needs, for example, collecting data at time intervals such as seconds, minutes, and hours, and cleaning and sorting the collected flow data to remove invalid data or abnormal data, so as to obtain the first flow information corresponding to the 5G exclusive spectrum bandwidth and the second flow information corresponding to the 4G exclusive spectrum bandwidth. Then, spectrum sharing judgment is performed based on the first flow information and the second flow information to obtain the spectrum sharing judgment result. There are many ways to implement spectrum sharing judgment, which are no longer limited in the embodiments of the present application. In one feasible method, a first sharing standard corresponding to the 5G exclusive spectrum bandwidth and a second sharing standard corresponding to the 4G exclusive spectrum bandwidth are obtained; 5G traffic analysis is performed based on the first traffic information and the first sharing standard to determine the first sharing judgment result, and 4G traffic analysis is performed based on the second traffic information and the second sharing standard to determine the second sharing judgment result; the first sharing judgment result and the second sharing judgment result are combined to obtain a spectrum sharing judgment result, wherein the first sharing judgment result, the second sharing judgment result and the spectrum sharing judgment result all include: enabling spectrum sharing and not enabling spectrum sharing. When any one of the first sharing judgment result and the second sharing judgment result is enabling spectrum sharing, the spectrum sharing judgment result is determined to be enabling spectrum sharing; otherwise, the spectrum sharing judgment result is determined to be not enabling spectrum sharing.

[0031] Step S103: When the spectrum sharing judgment result is to enable spectrum sharing, an allocation ratio analysis is performed based on the first traffic information and the second traffic information to determine the spectrum allocation ratio corresponding to the shared spectrum bandwidth, and spectrum sharing is performed according to the spectrum allocation ratio, wherein the spectrum allocation ratio is used to optimize spectrum resource utilization.

[0032] For the embodiment of the present application, when the spectrum sharing judgment result is that spectrum sharing is not enabled, it indicates that the 5G exclusive spectrum bandwidth and the 4G exclusive spectrum bandwidth can meet the current network conditions or business requirements, and thus, the 5G network and the 4G network are controlled to continue using their respective exclusive spectrum bandwidths.

[0033] When the spectrum sharing judgment result is to enable spectrum sharing, an allocation ratio analysis is performed based on the first traffic information and the second traffic information to determine the spectrum allocation ratio corresponding to the shared spectrum bandwidth, and the spectrum sharing is performed according to the spectrum allocation ratio, wherein the spectrum allocation ratio is used to divide the shared spectrum bandwidth to the 5G network and the 4G network in proportion. By analyzing the traffic information of the 5G network and the 4G network, it is helpful to more accurately understand the spectrum requirements of each network, and to allocate spectrum according to the spectrum requirements, which can avoid the waste of spectrum resources, improve the overall utilization of spectrum resources, and ensure that each network can obtain sufficient resources when sharing the spectrum, thereby maintaining stable network performance. There are many specific implementation methods for the allocation ratio analysis, which are no longer limited in the embodiments of the present application. In one achievable method, the first traffic information and the second traffic information include but are not limited to: real-time traffic usage, user distribution, network load and other information. In order to make the traffic information have the same dimension and comparability, the first traffic information and the second traffic information are normalized. Then, based on the first traffic information and the second traffic information, a multi-dimensional traffic feature analysis is performed to obtain the traffic feature analysis results. The multi-dimensional traffic feature analysis includes: traffic trend analysis, traffic distribution analysis, traffic demand prediction, etc., wherein the traffic trend analysis is used to analyze the time series data of 5G and 4G traffic, and identify the trend and periodicity of traffic changes; the traffic distribution analysis is used to analyze the geographical distribution, user distribution and time period distribution of 5G traffic and 4G traffic, and identify traffic peak and valley periods, as well as high traffic and low traffic areas; the traffic demand prediction is used to predict the traffic demand in the future based on historical traffic data and business development trends, and consider the impact of new services, new technologies and new equipment on traffic. Furthermore, based on the first traffic information and the second traffic information, a spectrum efficiency evaluation is performed to obtain a spectrum efficiency evaluation result. The spectrum efficiency evaluation includes: spectrum utilization analysis and spectrum efficiency comparison, wherein the spectrum utilization analysis calculates the spectrum utilization of 5G networks and 4G networks to identify the reasons for low spectrum utilization and potential room for improvement; the spectrum efficiency comparison is used to analyze the impact of factors such as different frequency bands and different modulation and coding methods on spectrum efficiency. Furthermore, according to the results of traffic feature analysis and spectrum efficiency evaluation, different weights are assigned to 5G networks and 4G networks. The weights should reflect the differences between different networks in terms of traffic demand, spectrum utilization, and spectrum efficiency. Then, according to the weights and traffic demand prediction results, the allocation ratio of shared spectrum bandwidth between 5G and 4G networks is calculated. This spectrum allocation ratio can not only meet the current traffic demand, but also reserve enough space for future traffic growth. Finally, spectrum sharing is carried out according to the spectrum allocation ratio. Spectrum sharing can dynamically use spectrum resources according to network traffic and user needs, ensuring that spectrum resources can be effectively used and avoiding waste of resources, so that 5G networks can use spectrum resources efficiently.

[0034] It can be seen that in the embodiment of the present application, spectrum division is performed based on the number of 5G users, the number of 4G users, and business needs, and the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth, and the shared spectrum bandwidth are determined. Performing spectrum division according to user data helps to ensure that 4G network users will not be greatly affected during the gradual expansion of the 5G network, and the 5G network can also obtain sufficient spectrum resources to support its rapid development. If the spectrum sharing state is always enabled, the overall network environment may cause network performance to deteriorate due to problems such as signal interference and resource competition. Therefore, in order to provide more stable and reliable communication services, the spectrum sharing judgment is performed first, the traffic requirements of different networks are matched more accurately, the first traffic information corresponding to the 5G exclusive spectrum bandwidth and the second traffic information corresponding to the 4G exclusive spectrum bandwidth are monitored in real time, and the spectrum sharing judgment is performed based on the first traffic information and the second traffic information to obtain the spectrum sharing judgment result. When the spectrum sharing judgment result is to enable spectrum sharing, an allocation ratio analysis is performed based on the first traffic information and the second traffic information to determine the spectrum allocation ratio corresponding to the shared spectrum bandwidth, and spectrum sharing is performed according to the spectrum allocation ratio. Spectrum sharing can dynamically use spectrum resources based on network traffic and user needs, ensuring that spectrum resources can be effectively utilized and avoiding waste of resources, so that 5G networks can efficiently utilize spectrum resources.

[0035] Further, in order to ensure that both networks can maintain the best performance and user experience, in the embodiment of the present application, after performing the allocation ratio analysis based on the first flow information and the second flow information to determine the spectrum allocation ratio corresponding to the shared spectrum bandwidth, it also includes: Obtain 5G network performance indicators and 4G network performance indicators, perform intelligent spectrum scheduling based on the 5G network performance indicators and 4G network performance indicators, determine the spectrum scheduling ratio corresponding to the shared spectrum bandwidth, and share the spectrum according to the spectrum scheduling ratio, where the spectrum scheduling ratio is used to ensure the user experience and network performance of the 5G network or the 4G network.

[0036] For the embodiment of the present application, a network monitoring tool is used to collect 5G network performance indicators and 4G network performance indicators in real time. The network performance indicators should be able to reflect the real-time status of the network and user needs, including but not limited to: throughput, delay, packet loss rate, spectrum utilization, signal quality and other information. Then, the 5G network performance indicators and 4G network performance indicators are cleaned and preprocessed to remove outliers and noise to ensure the accuracy and reliability of the data. Then, performance evaluation and trend prediction are performed based on the preprocessed 5G network performance indicators and 4G network performance indicators to obtain performance evaluation and trend prediction results, wherein the performance evaluation is used to evaluate the performance indicators of the 5G network and the 4G network according to the preset evaluation criteria and thresholds, and analyze the performance bottlenecks and potential problems of the network; trend prediction is used to use data analysis tools or algorithms to perform trend prediction on performance indicator data, and predict the changing trend of network performance and the changing situation of user needs in the future. Then, intelligent spectrum scheduling is performed based on the performance evaluation and trend prediction results to determine the spectrum scheduling ratio corresponding to the shared spectrum bandwidth. Of course, it can also include: scheduling cycle and scheduling granularity.

[0037] Intelligent spectrum scheduling can optimize the allocation of spectrum resources based on the performance indicators of 5G and 4G networks. For example, when the 5G network load is high, the spectrum resources of the 5G network can be dynamically increased to improve its network performance. Similarly, when the 4G network needs more resources, the spectrum allocation can be adjusted accordingly. The flexible scheduling mechanism can ensure that both networks can maintain the best performance and user experience.

[0038] It can be seen that in the embodiment of the present application, 5G network performance indicators and 4G network performance indicators are obtained, intelligent spectrum scheduling is performed based on the 5G network performance indicators and 4G network performance indicators, the spectrum scheduling ratio corresponding to the shared spectrum bandwidth is determined, and spectrum sharing is performed according to the spectrum scheduling ratio. The flexible scheduling mechanism can ensure that both networks can maintain the best performance status and user experience.

[0039] Further, in order to optimize spectrum allocation and improve the utilization rate of spectrum resources, in the embodiment of the present application, spectrum is divided based on the number of 5G users, the number of 4G users, and business needs, and after determining the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth, and the shared spectrum bandwidth, it also includes: When the spectrum division evaluation period is reached, a first spectrum utilization rate corresponding to the 5G exclusive spectrum bandwidth, a second spectrum utilization rate corresponding to the 4G exclusive spectrum bandwidth, and a third spectrum utilization rate corresponding to the shared spectrum bandwidth are obtained; A spectrum utilization optimization model is obtained, and a spectrum division evaluation is performed on the first spectrum utilization, the second spectrum utilization, and the third spectrum utilization using the spectrum utilization optimization model to determine the spectrum division evaluation result, wherein the spectrum division evaluation result includes: normal spectrum division and spectrum division to be optimized.

[0040] For the embodiments of the present application, with the continuous development of communication technologies such as 5G and 4G, the demand for spectrum resources is becoming increasingly diversified. Through spectrum division evaluation, the spectrum utilization of different frequency bands and different communication technologies can be understood, thereby optimizing spectrum allocation and improving the utilization of spectrum resources.

[0041] Specifically, when the spectrum division evaluation cycle is reached, the first spectrum utilization rate corresponding to the 5G exclusive spectrum bandwidth, the second spectrum utilization rate corresponding to the 4G exclusive spectrum bandwidth, and the third spectrum utilization rate corresponding to the shared spectrum bandwidth are obtained, wherein the spectrum division evaluation cycle is a reasonable spectrum division evaluation cycle pre-set according to the operation of the network communication system and the use of spectrum resources. During the spectrum division evaluation cycle, real-time data collection and measurement are performed on the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth, and the shared spectrum bandwidth to obtain the first spectrum utilization rate corresponding to the 5G exclusive spectrum bandwidth, the second spectrum utilization rate corresponding to the 4G exclusive spectrum bandwidth, and the third spectrum utilization rate corresponding to the shared spectrum bandwidth. The above spectrum utilization rate can be the ratio of the effective use time of the spectrum to the total time, or the ratio of the amount of effectively transmitted data to the total amount of spectrum resources. Then, a spectrum utilization optimization model is obtained, which is pre-stored in the electronic device and is obtained by training and verifying the machine learning model based on historical spectrum utilization data, communication system parameters, and user behavior data. Furthermore, the first spectrum utilization rate, the second spectrum utilization rate and the third spectrum utilization rate are taken as input data and input into the spectrum utilization optimization model, and the spectrum utilization optimization model is controlled to perform calculation and analysis according to the input data, and output the spectrum division evaluation result, that is, the analysis is performed from multiple aspects such as the rationality analysis of the spectrum division, the waste of spectrum resources, and potential spectrum optimization schemes. If the current spectrum division is reasonable, and the utilization rate of spectrum resources is high, and there is no obvious waste, then the spectrum division evaluation result is determined to be normal; if the current spectrum division is unreasonable, or the utilization rate of spectrum resources is low, and there is obvious waste, then the spectrum division evaluation result is determined to be spectrum division to be optimized.

[0042] It can be seen that in the embodiment of the present application, when the spectrum division evaluation cycle is reached, the first spectrum utilization corresponding to the 5G exclusive spectrum bandwidth, the second spectrum utilization corresponding to the 4G exclusive spectrum bandwidth, and the third spectrum utilization corresponding to the shared spectrum bandwidth are obtained. Then, the spectrum division evaluation is performed on the first spectrum utilization, the second spectrum utilization, and the third spectrum utilization using the spectrum utilization optimization model to determine the spectrum division evaluation result. Through the spectrum division evaluation, the spectrum utilization of different frequency bands and different communication technologies can be understood, thereby optimizing the spectrum allocation and improving the utilization of spectrum resources.

[0043] Furthermore, in order to improve the adaptability of the exclusive spectrum bandwidth to the business needs, in the embodiment of the present application, the spectrum is divided based on the number of 5G users, the number of 4G users, and the business needs, and the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth, and the shared spectrum bandwidth are determined, including: Analyze the growth trend based on the number of 5G users and 4G users to determine the change information of the number of 5G users and the change information of the number of 4G users; Analyze spectrum requirements based on 5G and 4G service requirements, and determine the spectrum priorities corresponding to spectrum in different frequency bands; Spectrum is divided based on the change information on the number of 5G users, the change information on the number of 4G users and the spectrum priority to determine the 5G exclusive spectrum bandwidth, 4G exclusive spectrum bandwidth and shared spectrum bandwidth.

[0044] For the embodiment of the present application, the number of 5G users is sorted according to the time series to form a time series data set, and the growth trend is predicted based on the time series data set to determine the change trend of 5G users in the future, which is recorded as the change information of the number of 5G users, including but not limited to: the growth rate, growth amount, growth rate, etc. of the number of 5G users. The process of analyzing the growth trend of the number of 4G users is similar to the growth trend analysis of the number of 5G users, and this embodiment of the present application will not be repeated. Since different network types have different business requirements, different business requirements also have different requirements for spectrum resources. Therefore, based on the 5G business requirements and 4G business requirements in the business requirements, a spectrum demand analysis is performed to determine the spectrum priorities corresponding to the spectrums of different frequency bands. The spectrum priority is used to characterize the matching degree of the spectrums of different frequency bands to different business requirements, so as to facilitate the allocation of the spectrum that meets the corresponding business requirements to the corresponding network type.

[0045] Specifically, 5G service requirements usually require high-capacity, high-speed spectrum resources to support high-definition video, virtual reality (VR) / augmented reality (AR) and other large data transmission services; wide coverage, low-power spectrum resources are required to support large-scale connection and data transmission of Internet of Things (IoT) devices; high reliability, low latency spectrum resources are required to support key services such as autonomous driving and telemedicine. However, 4G service requirements are mainly used to meet the needs of existing mobile communication services, including voice calls, mobile Internet access, text messages, etc. Furthermore, a comprehensive assessment is made based on factors such as the degree to which each frequency band spectrum meets 5G business needs and 4G business needs, technical feasibility, and economic cost, to determine the spectrum priorities corresponding to different frequency band spectrums. That is, when the frequency band spectrum can better adapt to 5G business needs, the priority of the frequency band spectrum for 5G business needs is set to high priority; otherwise, the priority of the frequency band spectrum for 5G business needs is set to low priority; similarly, when the frequency band spectrum can better adapt to 4G business needs, the priority of the frequency band spectrum for 4G business needs is set to high priority; otherwise, the priority of the frequency band spectrum for 4G business needs is set to low priority.

[0046] Finally, spectrum division is performed based on the change information of the number of 5G users, the change information of the number of 4G users and the spectrum priority, and the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth and the shared spectrum bandwidth are determined. When performing spectrum division, the spectrum of the frequency bands with high priority for 5G business needs will be allocated to the 5G exclusive spectrum bandwidth first; the spectrum of the frequency bands with high priority for 4G business needs will be allocated to the 4G exclusive spectrum bandwidth first; and the remaining spectrum bands will be allocated to the shared spectrum bandwidth. The spectrum priority is taken into account in the operation of performing spectrum division, which improves the adaptability of the exclusive spectrum bandwidth to business needs.

[0047] There are many ways to implement spectrum division, which are not limited in the embodiments of the present application. In one feasible method, the 5G exclusive spectrum bandwidth is calculated and determined according to the number of 5G users and the spectrum priority, that is, the frequency band spectrum with high priority for 5G business demand is preferentially allocated to the 5G exclusive spectrum bandwidth. Then, according to the number of 4G users and the spectrum priority, the 4G exclusive spectrum bandwidth is calculated and determined, that is, the frequency band spectrum with high priority for 4G business demand is preferentially allocated to the 4G exclusive spectrum bandwidth. Furthermore, based on the growth amount in the 5G user number change information, the growth amount in the 4G user number change information, and the spectrum priority, the shared spectrum is divided to determine the shared spectrum bandwidth.

[0048] It can be seen that in the embodiment of the present application, a growth trend analysis is performed based on the number of 5G users and the number of 4G users to determine the change information of the number of 5G users and the change information of the number of 4G users. Then, a spectrum demand analysis is performed based on the 5G business demand and the 4G business demand in the business demand, and the spectrum priority corresponding to the spectrum of different frequency bands is determined. Finally, spectrum division is performed based on the change information of the number of 5G users, the change information of the number of 4G users and the spectrum priority to determine the 5G exclusive spectrum bandwidth, the 4G exclusive spectrum bandwidth and the shared spectrum bandwidth. The spectrum priority is taken into account in the operation of performing spectrum division, which improves the adaptability of the exclusive spectrum bandwidth to business needs.

[0049] Further, in order to quickly enable spectrum sharing when additional spectrum bandwidth is needed, effectively utilize limited spectrum resources, and improve the overall capacity and performance of the network, in an embodiment of the present application, a spectrum sharing judgment is performed based on the first flow information and the second flow information to obtain a spectrum sharing judgment result, including: Obtain a first sharing standard corresponding to the 5G exclusive spectrum bandwidth and a second sharing standard corresponding to the 4G exclusive spectrum bandwidth; Perform 5G traffic analysis based on the first traffic information and the first sharing standard to determine a first sharing judgment result, and perform 4G traffic analysis based on the second traffic information and the second sharing standard to determine a second sharing judgment result; The first sharing determination result and the second sharing determination result are combined to obtain a spectrum sharing determination result.

[0050] For the embodiments of the present application, a first sharing standard corresponding to the 5G exclusive spectrum bandwidth and a second sharing standard corresponding to the 4G exclusive spectrum bandwidth are pre-stored in the electronic device. The first sharing standard and the second sharing standard respectively specify whether different exclusive spectrum bandwidths can meet the usage requirements of corresponding users, so as to quickly enable spectrum sharing when additional spectrum bandwidth is needed. Therefore, the sharing standard specifies multi-dimensional requirements for enabling spectrum sharing, such as traffic growth trend requirements, spectrum resource utilization efficiency requirements, etc.

[0051] Furthermore, a multi-dimensional feature extraction is performed based on the first traffic information to determine the traffic feature, and the traffic feature is matched with the first sharing standard. When the traffic feature meets any one of the requirements of the first sharing standard, the first sharing judgment result is determined to enable spectrum sharing; otherwise, the first sharing judgment result is determined to be non-enabling spectrum sharing. Similarly, a multi-dimensional feature extraction is performed based on the second traffic information to determine the traffic feature, and the traffic feature is matched with the second sharing standard. When the traffic feature meets any one of the requirements of the second sharing standard, the second sharing judgment result is determined to enable spectrum sharing; otherwise, the second sharing judgment result is determined to be non-enabling spectrum sharing. Finally, the first sharing judgment result and the second sharing judgment result are combined to obtain a spectrum sharing judgment result, that is, when any one of the first sharing judgment result and the second sharing judgment result is enabling spectrum sharing, the spectrum sharing judgment result is determined to be enabling spectrum sharing, otherwise, the spectrum sharing judgment result is determined to be non-enabling spectrum sharing. Spectrum sharing judgment helps to quickly enable spectrum sharing when additional spectrum bandwidth is needed, which can more effectively utilize limited spectrum resources and improve the overall capacity and performance of the network.

[0052] It can be seen that in the embodiment of the present application, the first sharing standard corresponding to the 5G exclusive spectrum bandwidth and the second sharing standard corresponding to the 4G exclusive spectrum bandwidth are obtained, and then, based on the first traffic information and the first sharing standard, the 5G traffic analysis is performed to determine the first sharing judgment result, and based on the second traffic information and the second sharing standard, the 4G traffic analysis is performed to determine the second sharing judgment result. Finally, the spectrum sharing judgment result is obtained by combining the first sharing judgment result and the second sharing judgment result. The spectrum sharing judgment can help to quickly enable spectrum sharing when additional spectrum bandwidth is needed, which can more effectively utilize limited spectrum resources and improve the overall capacity and performance of the network.
