first, if set to LTE priority mode: for example, the LTE priority spectrum resource proportion is set to 80%, and the NR spectrum resource is configured to 20%.
However, at the initial stage of 5G construction, the permeability of the 5G terminal is low, part of cells have no 5G terminal resident, if 20% of resources are still configured for 5G, the 4G congestion will further worsen due to insufficient resources which can be allocated for 4G.
The second, current dynamic spectrum sharing method is: a fixed threshold of the ratio of NR to LTE spectrum resources is set, for example, the ratio of LTE spectrum resources is 80% and the ratio of NR spectrum resources is 20%.
When the service requirements of LTE and NR are lower than the fixed resource proportion threshold set by each service requirement, the spectrum resources do not conflict; however, according to the characteristic that the data service "instantaneously occupies the full bandwidth and instantaneously releases", when the service request occurs between the user using the LTE spectrum resource and the user using the NR spectrum resource at the same time interval, the spectrum allocation of the LTE is set according to a fixed resource proportion threshold, that is, 80% at maximum; the spectrum allocation of NR is 20% at the maximum, and the average throughput of users using LTE spectrum resources cannot be guaranteed, nor the average throughput of users using NR spectrum resources.

Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The existing spectrum sharing method can lead to insufficient 4G allocable spectrum resources and congestion of a 4G network; and the fixed proportion threshold is used for the proportion threshold of the LTE spectrum resource and the NR spectrum resource, so that the actual spectrum resource allocation is not balanced and flexible enough.
In view of this, the inventive concept of the embodiments of the present application is: the base stations in the cluster are configured as the base stations using the LTE frequency spectrum resources at the beginning, so that when the permeability of the 5G terminal is low at the beginning of 5G, the 4G network has enough allocable frequency spectrum resources, and the problem of 4G network congestion is avoided; and the embodiment of the application can judge the busy/idle degree of the shared spectrum resource using the 5G network cell and the 4G network cell by detecting the first spectrum efficiency of the 5G network cell and the second spectrum efficiency of the 4G network cell in the cluster, and adjust the preset proportion threshold of the base station in the cluster according to the busy/idle degree of the 5G network cell and the 4G network cell, thereby realizing dynamic spectrum sharing. Compared with the existing spectrum sharing method which uses a fixed proportion threshold, the embodiment of the application dynamically adjusts the preset proportion threshold of NR spectrum resource and LTE spectrum resource allocation by using the first spectrum efficiency of the 5G network cell and the second spectrum efficiency of the 4G network cell, thereby realizing the improvement of spectrum resource allocation balance and flexibility and the improvement of spectrum utilization rate.
Fig. 1 is a dynamic spectrum sharing method. Referring to fig. 1, an embodiment of the present application provides a dynamic spectrum sharing method, which may include:
step 100, configuring base stations in a cluster as base stations using LTE spectrum resources, wherein the base stations in the cluster comprise NR base stations and LTE base stations in a preset geographic range;
the electronic device configures the base stations within the cluster as base stations using LTE spectrum resources. A specific electronic device may be configured with a certain number of NR base stations and LTE base stations that are adjacent to each other within a certain geographic range as base stations that use LTE spectrum resources. For example, 50 NR base stations adjacent to each other in a certain block of a certain city are set as base stations using LTE spectrum resources. Wherein, NR base station is the base station using 5G network, LTE base station is the base station using 4G network.
Specifically, the electronic device determines the frequency bands of the NR base station and the LTE base station, for example, n28:700MHz, n5:850MHz, n8:900MHz, n3:1800MHz, n1:2100MHz, and NR base stations share spectral resources of the spectrum with LTE base stations, e.g., 15MHz, 20MHz, 25MHz, etc. The electronic equipment configures all spectrum resources shared by the NR base station and the LTE base station into LTE base stations initially, and configures all base stations in the cluster into base stations using the LTE spectrum resources, namely, NR control channels and signals are not configured for the base stations in the cluster.
Step 200, detecting 5G service demand of base stations in the cluster;
in the embodiment of the application, the 5G service demand of the base stations in the cluster is used as the condition of starting or closing the dynamic spectrum sharing mode of the NR network and the LTE network. When the 5G traffic demand of the base stations in the cluster is large, which means that there is a demand for large NR spectrum resources, the proportion of spectrum resource allocation of the LTE base stations in the cluster needs to be adjusted. Otherwise, when the 5G service demand of the base stations in the cluster is smaller, the base stations in the cluster are configured to be base stations using LTE frequency spectrum resources, so that the 4G network has enough allocable frequency spectrum resources when the permeability of the 5G terminal in the initial stage of 5G is low, and the problem of 4G network congestion is avoided.
The electronic device detects a 5G traffic demand of base stations within the cluster. Specifically, in one embodiment, the electronic device may detect the number of 5G terminals accessed by the base stations in the cluster; or detecting the number of 5G terminals accessed by the base stations in the cluster and the duration time of the 5G terminals accessed by the base stations in the cluster; thereby enabling detection of 5G traffic demands of base stations within the cluster.
It can be understood that by detecting the number of 5G terminals accessed by the base stations in the cluster and the duration of the 5G terminals accessed by the base stations in the cluster, the number information of the 5G terminals accessed by the base stations in the cluster in a period of time can be acquired more accurately and stably. And the data of the 5G terminal which is temporarily connected with the base station is prevented from being recorded.
In this embodiment of the present application, two identification manners of the 5G terminal are provided, which are specifically as follows:
in the first way, when a 5G terminal accesses the network, the terminal reports the support double-link capability of the terminal through an atach_req message (NAS message, terminal notification 4G core network), and if 1 indicates support, 0 indicates no support. When the mark is 1, the 5G terminal is represented, and dual-connection EN-DC capability is supported; when the flag is 0, two possibilities are included, a 5G terminal but the handset interface has no 5G capability, or a 4G terminal.
In the second way, after the radio resource connection (Radio Resource Control, abbreviated as RRC) serving as the access portion of the signaling connection is completed, the base station queries the capability of the UE for the first time through rrc_ue_cap_request signaling. The ue reports the capability (UU port message, terminal informs the 4G base station) in the rrc_eutra_cap message, if EN-DC-R15 is Supported, it indicates that the ue supports 5G capability (consistent with the meaning of the double-connectivity identifier being 1), otherwise, it indicates a non-5G terminal.
Step 300, under the condition that the 5G service demand reaches a set threshold, starting a dynamic spectrum sharing mode of an NR network and an LTE network for all base stations in the cluster, wherein the dynamic spectrum sharing mode comprises a preset proportion threshold of LTE spectrum resource allocation;
specifically, the 5G traffic demand reaches a set threshold, including: the number of 5G terminals accessed by the base stations in the cluster reaches a set threshold; or the number of the 5G terminals accessed by the base stations in the cluster reaches a set threshold, and the duration time of the 5G terminals accessed by the base stations in the cluster reaches a set time threshold.
It can be understood that the setting threshold and the setting time threshold may be set according to actual situations, and are not specifically limited in the embodiments of the present application.
The number of 5G terminals accessed by the base stations in the cluster reaches a set threshold; or when the number of the 5G terminals accessed by the base stations in the cluster reaches a set threshold value and the duration time of the 5G terminals accessed by the base stations in the cluster reaches a set time threshold value, the requirement of larger NR spectrum resources is indicated at the moment, and the proportion of spectrum resource allocation of the LTE base stations in the cluster needs to be adjusted. Namely, the electronic equipment starts a NR network and LTE network dynamic spectrum sharing mode for all base stations in the cluster.
The dynamic spectrum sharing mode comprises a preset proportion threshold of LTE spectrum resource allocation. The preset proportional threshold may be preset, for example, a preset proportional threshold for NR spectrum resource and LTE spectrum resource allocation is set to 2:8.
step 400, detecting first spectrum efficiency of using 5G network cells and second spectrum efficiency of using 4G network cells in the cluster;
electronically detecting a first spectral efficiency using a 5G network cell and a second spectral efficiency using a 4G network cell within the cluster. According to the method and the device, the first spectrum efficiency of the 5G network cell and the second spectrum efficiency of the 4G network cell in the cluster are detected, the busy/idle degree of the 5G network cell and the 4G network cell which share spectrum resources can be judged, and the preset proportion threshold of the base station in the cluster is adjusted according to the busy/idle degree of the 5G network cell and the 4G network cell, so that dynamic spectrum sharing is achieved.
Specifically, in one embodiment, the electronic device detects a first spectral efficiency of using a 5G network cell and a second spectral efficiency of using a 4G network cell within the cluster, including:
the electronic device detects the first spectrum efficiency by detecting a number of service bytes of a radio link control layer protocol using the 5G network cell for a preset time interval.
And the electronic equipment detects the second spectrum efficiency by detecting the number of service bytes of a wireless link control layer protocol of the preset time interval using the 4G network cell.
The number of service bytes of the cell radio link control layer protocol (english: radio Link Control, hereinafter RLC) includes: RLC downlink service byte count (in GB) and RLC uplink service byte count (in GB) are applicable to use of 5G network cells and use of 4G network cells. The number of the downlink service bytes of the RLC is specifically the total throughput of downlink data sent by the cell RLC layer; the RLC uplink service byte number is specifically the total throughput of uplink data received by the RLC layer of the cell. It should be noted that, the preset time interval t1 needs to be selected to have a time granularity as small as possible, for example, a minute is taken as the time granularity of the preset time interval t1, so as to compare the spectrum efficiency of using the 5G network cell with that of using the 4G network cell.
According to the embodiment of the application, the frequency spectrum efficiency is represented by the cell RLC service byte number of the preset time interval, the practical conditions of access users and service demands of the 5G network cell, the access users using the 4G network cell and the service demands can be comprehensively used, and the number of the RLC service bytes represents the uplink and downlink average throughput of all users in one time period, and the statistics of the number of the users and the statistics of the service types (big packet cell and small packet cell) of the service application are included, so that the phenomenon that the users of more small packet cells occupy a large bandwidth or the users of less big packet cells occupy the distribution of a small bandwidth is avoided.
Wherein, the big packet cell and the small packet cell are defined as follows:
big packet cell: the average E-RAB traffic of the cell in the busy hour is more than or equal to 1000KB.
The middle packet cell: the average E-RAB traffic of the cell in the self busy time is more than or equal to 300KB and less than 1000KB.
Packet cell: the average E-RAB traffic during the cell is less than 300KB.
And 500, adjusting a preset proportional threshold of the base stations in the cluster based on the first spectrum efficiency or the second spectrum efficiency to realize dynamic spectrum sharing.
And the electronic equipment adjusts a preset proportional threshold of the base stations in the cluster based on the first frequency spectrum efficiency or the second frequency spectrum efficiency, so as to realize dynamic frequency spectrum sharing.
The electronic device can judge the busy/idle degree of the shared spectrum resource using the 5G network cell and the 4G network cell by calculating the first spectrum efficiency of the 5G network cell and the second spectrum efficiency of the 4G network cell, and dynamically adjust the preset proportion threshold according to the busy/idle degree of the 5G network cell and the 4G network cell. The method and the device have the advantages that the proportion threshold of NR spectrum resource and LTE spectrum resource allocation is dynamically adjusted, the spectrum resource allocation balance and flexibility are improved, and the spectrum utilization rate is improved.
Specifically, in one embodiment, step 500, the adjusting the preset ratio threshold of the base stations in the cluster based on the first spectrum efficiency or the second spectrum efficiency to implement dynamic spectrum sharing includes:
step 510, summing the preset proportional threshold and a preset step value to obtain a first adjustment proportional threshold when the first spectral efficiency is greater than the second spectral efficiency; adjusting the base stations in the cluster to perform dynamic spectrum sharing based on the first adjustment proportion threshold;
for example, in the embodiment of the present application, 1 minute is used as the time granularity, and the LTE spectrum resource and the NR spectrum resource are allocated according to the preset ratio threshold T1 of the initial LTE spectrum resource and the NR spectrum resource, as shown in fig. 2 (a), and fig. 2 shows the ratio threshold for the LTE spectrum resource and the NR spectrum resource allocation in three cases. Assuming that the preset ratio threshold T1 of the LTE spectrum resource and the NR spectrum resource is 80% at this time, the NR spectrum resource allocation is 20%.
When the first spectrum efficiency e_2 of the 5G network cell is greater than the second spectrum efficiency e_1 of the 4G network cell, the spectrum efficiency of the 5G network cell is higher than that of the 4G network cell, the LTE spectrum resource of the 4G network cell is insufficient, and the preset proportional threshold T1 can be dynamically increased. In one embodiment, the electronic device may sum the preset proportional threshold with a preset step value to obtain a first adjustment proportional threshold, for example, the first adjustment proportional threshold=t1+the preset step value (for example, may be 5%), that is, the first adjustment proportional threshold=t1+5% =80+5% =85%, and the corresponding NR spectrum resource allocation is 1-85% =15%. As shown in fig. 2 (b).
Or, in step 520, when the first spectrum efficiency is smaller than the second spectrum efficiency, the preset proportional threshold is differentiated from the preset step value to obtain a second adjustment proportional threshold; and adjusting the base stations in the cluster to perform dynamic spectrum sharing based on the second adjustment proportion threshold.
When the first spectrum efficiency e_2 of the 5G network cell is smaller than the second spectrum efficiency e_1 of the 4G network cell, the spectrum efficiency of the 4G network cell is higher than that of the 5G network cell, the NR spectrum resource of the 5G network cell is insufficient, the electronic device may dynamically reduce the preset proportion threshold T1 of the LTE spectrum resource, and the preset proportion threshold is differentiated from the preset step value to obtain the second adjustment proportion threshold. Specifically, in one embodiment, the second adjustment ratio threshold=t1—step size value (for example, may be 5%), that is, the second adjustment ratio threshold=t1-5% =80% -5% =75%; the corresponding NR spectrum resource allocation at this time is 1-75% = 25%. As shown in fig. 2 (c).
Therefore, by detecting the first spectrum efficiency of the 5G network cell and the second spectrum efficiency of the 4G network cell used in the cluster, the busy/idle degree of the 5G network cell used and the 4G network cell used for sharing spectrum resources can be judged, and the preset proportion threshold of the base station in the cluster is adjusted according to the busy/idle degree of the 5G network cell used and the 4G network cell used.
In summary, in the embodiment of the present application, by initially configuring the base stations in the cluster as the base stations using LTE spectrum resources, when the permeability of the 5G terminal in the initial stage of 5G is low, the 4G network has enough allocable spectrum resources, so that the problem of congestion of the 4G network is avoided; and the embodiment of the application can judge the busy/idle degree of the shared spectrum resource using the 5G network cell and the 4G network cell by detecting the first spectrum efficiency of the 5G network cell and the second spectrum efficiency of the 4G network cell in the cluster, and adjust the preset proportion threshold of the base station in the cluster according to the busy/idle degree of the 5G network cell and the 4G network cell, thereby realizing dynamic spectrum sharing. Compared with the existing spectrum sharing method which uses a fixed proportion threshold, the embodiment of the application dynamically adjusts the preset proportion threshold of NR spectrum resource and LTE spectrum resource allocation by using the first spectrum efficiency of the 5G network cell and the second spectrum efficiency of the 4G network cell, thereby realizing the improvement of spectrum resource allocation balance and flexibility and the improvement of spectrum utilization rate.
In other aspects of the present application, referring to fig. 3, step 500, after the step of implementing dynamic spectrum sharing, further includes:
step 600, performing power allocation on the 5G network cell and the 4G network cell based on the first adjustment ratio threshold or the second adjustment ratio threshold.
It should be noted that, in the case that the allocation of the LTE spectrum resources changes, in order to correspond to the change of the allocation of the LTE spectrum resources, the embodiment of the present application implements more reasonable power resource allocation. Thus, the electronic device allocates power to the using 5G network cell and the using 4G network cell based on the first scaling threshold or the second scaling threshold. In other words, the power allocation ratio of the using 5G network cell and the using 4G network cell is kept consistent with the first spectral efficiency and the second spectral efficiency.
The embodiment of the application realizes the linkage of power distribution along with spectrum distribution, namely, the proportion of the total occupied power of a single-system cell is equal to the proportion of the total occupied spectrum.
For example: taking maximum power specification 2×40w=80w as an example, if using 4G network cells to use 80% of spectrum resources, allocating power of 2×40w=2x32w=16w for using 4G network cells, and allocating power of 2×8w=16w for using 5G network cells.
In other aspects of the present application, referring to fig. 4, the dynamic spectrum sharing in the embodiment of the present application further includes:
step 700, under the condition that the number of 5G terminals accessed by the base stations in the cluster is detected to not reach a set threshold value; or under the condition that the number of the 5G terminals accessed by the base stations in the cluster is detected to not reach a set threshold value and the duration time of the 5G terminals accessed by the base stations in the cluster does not reach a set time threshold value; and turning off the dynamic spectrum sharing mode of all base stations of the cluster.
