Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a dynamic spectrum sharing method, apparatus, and electronic device. Background Technology

[0002] Currently, in the early stages of 5G deployment in the mobile communications field, if operators possess low-frequency sub-3GHz FDD (Frequency Division Dual) LTE (Long Term Evolution) spectrum resources, such as Band 1: 2100MHz and Band 3: 1800MHz, they can consider using spectrum sharing to configure FDD NR (New RAN) and FDD LTE on the same spectrum, thereby enabling rapid deployment of 5G networks.

[0003] The existing dynamic spectrum sharing between FDD NR and FDD LTE has significant shortcomings:

[0004] First, if set to LTE priority mode: for example, set the LTE priority spectrum resource ratio to 80% and the NR spectrum resource configuration to 20%.

[0005] However, we are currently in the early stages of 5G construction, with low 5G terminal penetration and some communities having no 5G terminals. If we still allocate 20% of resources to 5G, it will inevitably lead to insufficient resources available for 4G, and 4G congestion will worsen further.

[0006] Second, the current dynamic spectrum sharing method is to set a fixed threshold for the ratio of NR to LTE spectrum resources, such as 80% for LTE spectrum resources and 20% for NR spectrum resources.

[0007] When the service demand of LTE and NR is lower than their respective fixed resource ratio thresholds, spectrum resources do not conflict. However, according to the characteristics of data services, which "instantly occupy the full bandwidth and release it instantly", when users using LTE spectrum resources and users using NR spectrum resources make service requests in the same time interval, the spectrum allocation of LTE is set according to a fixed resource ratio threshold, that is, a maximum of 80%; the maximum spectrum allocation of NR is 20%. This cannot guarantee the average throughput of users using LTE spectrum resources, nor can it guarantee the average throughput of users using NR spectrum resources.

[0008] The existing spectrum sharing method leads to insufficient 4G spectrum resources, resulting in 4G network congestion; and the fixed ratio threshold for LTE spectrum resources and NR spectrum resources results in an unbalanced and inflexible allocation of spectrum resources in practice. Summary of the Invention

[0009] This application provides a dynamic spectrum sharing method, apparatus, and electronic device to address the technical problems of existing spectrum sharing methods leading to insufficient 4G allocable spectrum resources and 4G network congestion, and the use of fixed ratio thresholds for LTE and NR spectrum resources, resulting in unbalanced and inflexible spectrum resource allocation in practice.

[0010] In a first aspect, embodiments of this application provide a dynamic spectrum sharing method, including:

[0024] The second spectrum efficiency is detected by detecting the number of service bytes of the radio link control layer protocol of a 4G network cell at a preset time interval.

[0025] In one embodiment, adjusting a preset ratio threshold for base stations within the cluster based on the first spectral efficiency or the second spectral efficiency to achieve dynamic spectrum sharing includes:

[0026] When the first spectral efficiency is greater than the second spectral efficiency, the preset ratio threshold is summed with a preset step size value to obtain a first adjustment ratio threshold; the base stations within the cluster are adjusted to perform dynamic spectrum sharing based on the first adjustment ratio threshold; or

[0027] If the first spectral efficiency is less than the second spectral efficiency, the difference between the preset ratio threshold and the preset step size value is calculated to obtain the second adjustment ratio threshold; the base stations within the cluster are adjusted to perform dynamic spectrum sharing based on the second adjustment ratio threshold.

[0028] In one embodiment, the dynamic spectrum sharing method further includes:

[0029] Power allocation is performed on the 5G network cell and the 4G network cell based on the first adjustment ratio threshold or the second adjustment ratio threshold.

[0030] In one embodiment, the dynamic spectrum sharing method further includes:

Compared to existing spectrum sharing methods that use fixed ratio thresholds, this application dynamically adjusts the preset ratio threshold for NR and LTE spectrum resource allocation by using the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells, thereby improving the balance and flexibility of spectrum resource allocation and increasing spectrum utilization.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Existing spectrum sharing methods can lead to insufficient 4G spectrum resources, resulting in 4G network congestion; and the fixed threshold for the ratio of LTE spectrum resources to NR spectrum resources makes the actual allocation of spectrum resources unbalanced and inflexible.

[0053] Therefore, the inventive concept of this application is as follows: initially, the base stations within the cluster are configured as base stations using LTE spectrum resources. This ensures that in the early stages of 5G, when 5G terminal penetration is low, the 4G network has sufficient allocable spectrum resources, avoiding 4G network congestion. Furthermore, by detecting the first spectral efficiency of the 5G network cells and the second spectral efficiency of the 4G network cells within the cluster, the busy / idle levels of the 5G and 4G network cells sharing spectrum resources can be determined. Based on these levels, a preset ratio threshold for the base stations within the cluster is adjusted to achieve dynamic spectrum sharing. Compared to existing spectrum sharing methods that use fixed ratio thresholds, this application dynamically adjusts the preset ratio threshold for NR and LTE spectrum resource allocation by using the first spectral efficiency of the 5G network cells and the second spectral efficiency of the 4G network cells, thereby improving the balance and flexibility of spectrum resource allocation and increasing spectrum utilization.

[0054] Figure 1 This is a dynamic spectrum sharing method. Please refer to [link / reference]. Figure 1 This application provides a dynamic spectrum sharing method, which may include:

[0055] Step 100: Configure the base stations within the cluster as base stations using LTE spectrum resources. The base stations within the cluster include NR base stations and LTE base stations within a preset geographical range.

[0056] The base stations within the electronic equipment configuration cluster are base stations using LTE spectrum resources. Specific electronic equipment can be configured to house a certain number of adjacent NR and LTE base stations within a specific geographical area, all using LTE spectrum resources. For example, 50 adjacent NR and LTE base stations within a certain block of a city can be configured to use LTE spectrum resources. The NR base stations will use 5G networks, and the LTE base stations will use 4G networks.

[0057] Specifically, the electronic equipment determines the frequency bands of NR and LTE base stations, such as n28: 700MHz, n5: 850MHz, n8: 900MHz, n3: 1800MHz, and n1: 2100MHz, as well as the spectrum resources shared by NR and LTE base stations, such as 15MHz, 20MHz, and 25MHz. The electronic equipment then initially configures all the shared spectrum resources for LTE base stations, configuring all base stations within the cluster to use LTE spectrum resources; that is, it does not configure NR control channels and signals for the base stations within the cluster.

[0058] Step 200: Detect the 5G service demand of the base stations within the cluster;

[0059] In this embodiment, the 5G service demand of base stations within a cluster is used as the condition for enabling or disabling the dynamic spectrum sharing mode between the NR and LTE networks. When the 5G service demand of base stations within a cluster is high, it indicates a significant need for NR spectrum resources, requiring adjustment of the spectrum resource allocation ratio of the LTE base stations within the cluster. Conversely, when the 5G service demand of base stations within a cluster is low, the base stations within the cluster are configured to use LTE spectrum resources. This ensures that in the early stages of 5G development when 5G terminal penetration is low, the 4G network has sufficient allocable spectrum resources, avoiding 4G network congestion.

[0060] The electronic device detects the 5G service demand of the base stations within the cluster. Specifically, in one embodiment, the electronic device can detect the 5G service demand of the base stations within the cluster by detecting the number of 5G terminals accessing the base stations within the cluster; or by detecting the number of 5G terminals accessing the base stations within the cluster, and the duration of the 5G terminals accessing the base stations within the cluster; thereby realizing the detection of the 5G service demand of the base stations within the cluster.

[0061] Understandably, by detecting the number of 5G terminals connected to the base stations within the cluster, and the duration of these connections, it is possible to obtain more accurate and stable information about the number of 5G terminals connected to the base stations within the cluster over a given period. This avoids recording data on short-lived connections of 5G terminals to base stations.

[0062] In this application embodiment, there are two methods for identifying 5G terminals, as detailed below:

[0063] In the first method, when a 5G terminal joins the network, it reports its support for dual-connectivity capability via the ATTACH_REQ message (NAS message, used by the terminal to notify the 4G core network). A value of 1 indicates support, while a value of 0 indicates no support. When the flag is 1, it means the 5G terminal supports dual-connectivity EN-DC capability; when the flag is 0, there are two possibilities: it is a 5G terminal but the phone interface does not show 5G capability, or it is a 4G terminal.

[0064] In the second method, after the Radio Resource Control (RRC) connection, which is the access part of the signaling connection, is connected to the base station, the base station queries the user equipment's capabilities for the first time through the RRC_UE_CAP_ENQUIRY signaling. The user equipment reports its capabilities in the RRC_EUTRA_CAP message (UU interface message, the terminal notifies the 4G base station). If EN-DC-R15 is Supported, it indicates that the user equipment supports 5G capabilities (consistent with the meaning of dual-link capability identifier 1); otherwise, it indicates that it is not a 5G terminal.

[0065] Step 300: When the 5G service demand reaches a set threshold, enable the dynamic spectrum sharing mode between the NR network and the LTE network for all base stations in the cluster. The dynamic spectrum sharing mode includes a preset ratio threshold for LTE spectrum resource allocation.

[0066] Specifically, the 5G service demand reaching a set threshold includes: the number of 5G terminals accessed by the base stations within the cluster reaching a set threshold; or the number of 5G terminals accessed by the base stations within the cluster reaching a set threshold, and the duration of 5G terminals accessed by the base stations within the cluster reaching a set time threshold.

[0067] It is understandable that the threshold setting and the time threshold setting can be set according to the actual situation, and no specific limitation is made in this application embodiment.

[0068] When the number of 5G terminals connected to a base station within the cluster reaches a set threshold; or when the number of 5G terminals connected to a base station within the cluster reaches a set threshold and the duration of 5G terminal access to a base station within the cluster reaches a set time threshold, it indicates a significant demand for NR spectrum resources, necessitating an adjustment to the spectrum resource allocation ratio of LTE base stations within the cluster. In other words, the electronic equipment enables a dynamic spectrum sharing mode between the NR and LTE networks for all base stations within the cluster.

[0069] The dynamic spectrum sharing mode includes a preset ratio threshold for LTE spectrum resource allocation. This preset ratio threshold can be pre-set, for example, by setting the preset ratio threshold for NR spectrum resource allocation to LTE spectrum resource allocation to 2:8.

[0070] Step 400: Detect the first spectral efficiency of the 5G network cell and the second spectral efficiency of the 4G network cell within the cluster;

[0071] The system electronically detects the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells within the cluster. This embodiment of the application, by detecting the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells within the cluster, can determine the busy / idle levels of 5G network cells and 4G network cells sharing spectrum resources. Based on these busy / idle levels, a preset ratio threshold for base stations within the cluster is adjusted to achieve dynamic spectrum sharing.

[0072] Specifically, in one embodiment, the electronic device detects a first spectral efficiency of 5G network cells and a second spectral efficiency of 4G network cells within the cluster, including:

[0073] The electronic device detects the first spectrum efficiency by detecting the number of service bytes using the radio link control layer protocol of a 5G network cell at a preset time interval.

[0074] The electronic device detects the second spectrum efficiency by detecting the number of service bytes using the radio link control layer protocol of a 4G network cell at a preset time interval.

[0075] The Radio Link Control (RLC) service byte count includes: RLC downlink service byte count (in GB) and RLC uplink service byte count (in GB), applicable to both 5G and 4G network cells. Specifically, the RLC downlink service byte count represents the total downlink data throughput transmitted by the cell's RLC layer; the RLC uplink service byte count represents the total uplink data throughput received by the cell's RLC layer. It should be noted that the preset time interval t1 should be selected with the smallest possible time granularity, such as minutes, to facilitate comparison of the spectral efficiency of 5G and 4G network cells.

[0076] This application embodiment uses the number of RLC service bytes per cell at a preset time interval to characterize spectrum efficiency. It can comprehensively consider the actual situation of access users and service demands of 5G network cells and 4G network cells. Since the number of RLC service bytes represents the average uplink and downlink throughput of all users in a time period, it includes the statistics of the number of users applying for services and the statistics of service types (large packet cells, small packet cells), thus avoiding the uneven distribution phenomenon where many small packet cell users occupy large bandwidth or few large packet cell users occupy small bandwidth.

[0077] The definitions of large and small residential communities are as follows:

[0078] Large-scale cell: The average E-RAB traffic during the cell's busy period is greater than or equal to 1000KB.

[0079] Medium-sized cell: The average E-RAB traffic during the cell's busy period is greater than or equal to 300KB and less than 1000KB.

[0080] Small cell: The average E-RAB traffic during the cell's busy period is less than 300KB.

[0081] Step 500: Adjust the preset ratio threshold of the base stations within the cluster based on the first spectrum efficiency or the second spectrum efficiency to achieve dynamic spectrum sharing.

[0082] Electronic devices adjust a preset ratio threshold of base stations within the cluster based on the first spectral efficiency or the second spectral efficiency to achieve dynamic spectrum sharing.

[0083] Electronic devices can determine the workload levels of shared spectrum resources by calculating the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells. Based on these workload levels, they can dynamically adjust a preset ratio threshold. This allows for dynamic adjustment of the allocation ratio between NR and LTE spectrum resources, improving the balance and flexibility of spectrum resource allocation and increasing spectrum utilization.

[0084] Specifically, in one embodiment, step 500, adjusting a preset ratio threshold for base stations within the cluster based on the first spectral efficiency or the second spectral efficiency to achieve dynamic spectrum sharing, includes:

[0085] Step 510: When the first spectral efficiency is greater than the second spectral efficiency, the preset ratio threshold is summed with the preset step size value to obtain the first adjustment ratio threshold; the base stations within the cluster are adjusted to perform dynamic spectrum sharing based on the first adjustment ratio threshold.

[0086] For example, this application embodiment uses 1 minute as the time granularity, and allocates LTE spectrum resources and NR spectrum resources according to a preset ratio threshold T1 of the initial LTE spectrum resources and NR spectrum resources. Figure 2 As shown in (a), Figure 2 This represents the threshold ratio for LTE and NR spectrum resource allocation under three different scenarios. Assuming the preset threshold T1 for the ratio of LTE and NR spectrum resources is 80%, then the NR spectrum resource allocation is 20%.

[0087] When the first spectral efficiency E_2 of the 5G network cell is greater than the second spectral efficiency E_1 of the 4G network cell, it indicates that the spectral efficiency of the 5G network cell is higher than that of the 4G network cell, suggesting that the LTE spectrum resources of the 4G network cell are insufficient. In this case, the preset proportional threshold T1 can be dynamically increased. In one embodiment, the electronic device can sum the preset proportional threshold with a preset step size value to obtain a first adjustment proportional threshold. For example, the first adjustment proportional threshold = T1 + preset step size value (e.g., 5%), i.e., the first adjustment proportional threshold = T1 + 5% = 80 + 5% = 85%. Correspondingly, the NR spectrum resource allocation at this time is 1 - 85% = 15%. Figure 2 As shown in (b).

[0088] Alternatively, in step 520, if the first spectral efficiency is less than the second spectral efficiency, the difference between the preset ratio threshold and the preset step size value is calculated to obtain the second adjustment ratio threshold; the base stations within the cluster are adjusted to perform dynamic spectrum sharing based on the second adjustment ratio threshold.

[0089] When the first spectral efficiency E_2 of the 5G network cell is less than the second spectral efficiency E_1 of the 4G network cell, it indicates that the spectral efficiency of the 4G network cell is higher than that of the 5G network cell. This suggests that the NR spectrum resources of the 5G network cell are insufficient. The electronic device can dynamically reduce the preset proportion threshold T1 of the LTE spectrum resources. The difference between the preset proportion threshold and the preset step size value is used to obtain the second adjustment proportion threshold. Specifically, in one embodiment, the second adjustment proportion threshold = T1 - step size value (e.g., 5%), that is, the second adjustment proportion threshold = T1 - 5% = 80% - 5% = 75%; correspondingly, the NR spectrum resource allocation is 1 - 75% = 25%. Figure 2 As shown in (c).

[0090] By detecting the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells within the cluster, the busy / idle levels of 5G network cells and 4G network cells sharing spectrum resources can be determined. Based on the busy / idle levels of 5G network cells and 4G network cells, a preset ratio threshold for base stations within the cluster is adjusted. In this embodiment, the preset ratio threshold for the allocation of NR spectrum resources and LTE spectrum resources is dynamically adjusted to improve the balance and flexibility of spectrum resource allocation and increase spectrum utilization.

[0091] In summary, this embodiment configures base stations within a cluster to use LTE spectrum resources from the outset. This ensures that, in the early stages of 5G development when 5G terminal penetration is low, the 4G network has sufficient allocable spectrum resources, avoiding 4G network congestion. Furthermore, by detecting the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells within the cluster, this embodiment determines the workload levels of the 5G and 4G network cells sharing spectrum resources. Based on these workload levels, it adjusts a preset ratio threshold for the base stations within the cluster, achieving dynamic spectrum sharing. Compared to existing spectrum sharing methods that use fixed ratio thresholds, this embodiment dynamically adjusts the preset ratio threshold for NR and LTE spectrum resource allocation by using the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells, thereby improving the balance and flexibility of spectrum resource allocation and increasing spectrum utilization.

[0092] For other aspects of this application, please refer to Figure 3 After step 500, which involves adjusting a preset ratio threshold for base stations within the cluster based on the first or second spectral efficiency to achieve dynamic spectrum sharing, the method further includes:

[0093] Step 600: Perform power allocation between the 5G network cell and the 4G network cell based on the first adjustment ratio threshold or the second adjustment ratio threshold.

[0094] It should be noted that, in the event of changes in the allocation of LTE spectrum resources, this embodiment of the application aims to achieve a more reasonable power resource allocation to correspond to these changes. Therefore, the electronic device allocates power to the 5G network cell and the 4G network cell based on either the first adjustment ratio threshold or the second adjustment ratio threshold. In other words, the power allocation ratio between the 5G network cell and the 4G network cell is consistent with the first spectrum efficiency and the second spectrum efficiency.

[0095] The embodiments of this application realize that power allocation is linked with spectrum allocation, that is, the proportion of total power occupied by a single type cell is equal to the proportion of total spectrum occupied by it.

[0096] For example, taking the maximum power specification of 2*40W=80W as an example, if a 4G network cell uses 80% of the spectrum resources, then the power allocated to the 4G network cell is 2*40W*80%=2*32W=64W, and the power allocated to the 5G network cell is 2*8W=16W.

[0097] For other aspects of this application, please refer to Figure 4 The dynamic spectrum sharing in this application embodiment also includes:

[0098] Step 700: If the number of 5G terminals accessed by the base station in the cluster does not reach a set threshold; or if the number of 5G terminals accessed by the base station in the cluster does not reach a set threshold, and the duration of 5G terminals accessed by the base station in the cluster does not reach a set time threshold; disable the dynamic spectrum sharing mode of all base stations in the cluster.

[0099] If an electronic device detects that the number of 5G terminals accessing a base station within a cluster has not reached a set threshold, or if the number of 5G terminals accessing a base station within a cluster has not reached a set threshold, and the duration of 5G terminal access to a base station within a cluster has not reached a set time threshold, then when there are few users using 5G terminals in the cluster, it deletes the NR channel and signal configuration for all base stations in the cluster and disables the dynamic spectrum sharing mode for all base stations in the cluster. The base stations within the cluster are then configured to use LTE spectrum resources, ensuring that in the early stages of 5G deployment when 5G terminal penetration is low, the 4G network has sufficient allocable spectrum resources, thus avoiding 4G network congestion.

[0100] The dynamic spectrum sharing device provided in the embodiments of this application is described below. The dynamic spectrum sharing device described below and the dynamic spectrum sharing method described above can be referred to in correspondence.

Compared to existing spectrum sharing methods that use fixed ratio thresholds, this application embodiment dynamically adjusts the preset ratio threshold for NR and LTE spectrum resource allocation by using the first spectral efficiency of 5G network cells and the second spectral efficiency of 4G network cells, thereby improving the balance and flexibility of spectrum resource allocation and increasing spectrum utilization.
