In the present application, resources may be shared between different networks, where a terminal device in one network may use resources in the other network. In the following, different networks are described in connection with fig. 1-2.

Hereinafter, the technical means shown in the present application will be described in detail by specific examples. It should be noted that the following embodiments may be combined with each other, and the description of the same or similar contents is not repeated in different embodiments.
Fig. 4 is a flowchart illustrating a resource scheduling method according to an embodiment of the present invention. Referring to fig. 4, the method may include:
s401, the network equipment obtains the resource occupancy rate of the cell resource of the first cell.
In the practical application process, the network device schedules resources for the terminal device, when the terminal device needs to access the core network, the network device determines the resources required by the terminal device to access the core network, the resources may be called scheduling resources, and the scheduling resources are allocated to the terminal device, so that the terminal device accesses the core network through the scheduling resources. For example, when the terminal device needs to access the core network, the terminal device sends an access request to the network device, and the network device determines that resources need to be scheduled for the terminal device according to the access request, and accordingly, the network device may schedule resources for the terminal device through the steps shown in S401 to S402.
Hereinafter, a process of determining, by a network device, a scheduling resource of a first terminal device is described as an example, where the first terminal device is located in a first cell, and the first terminal device may be any terminal device that needs to perform resource scheduling in the first cell.
The cell resource of the first cell refers to a resource allocated to the first cell (or a terminal device in the first cell), and all terminal devices in the first cell can use the cell resource of the first cell. For example, referring to fig. 1, the cell resource of cell 1 is resource 1, and the cell resource of cell 2 is resource 2.
The resource occupancy of the cell resource of the first cell refers to a ratio of the amount of the resource used in the cell resource to the total amount of the cell resource.
Optionally, the cell resources of the first cell may include resources that can be preempted by the terminal device in the third cell. The resources that can be preempted by the terminal device in the third cell may also be referred to as preemptible resources. The third cell may be the same cell as the second cell. The preemptible resource may be a part of the cell resource or may be all of the cell resource, and in an actual application process, the proportion of the preemptible resource in the cell resource may be set according to actual needs. For example, the preemptible resource may be 40% of the cell resource, and in an actual application process, the ratio of the preemptible resource to the cell resource may be determined according to the service of the terminal device, the size of the cell resource, and the like.
S402, the network equipment judges that the resource occupancy rate of the cell resource of the first cell is larger than or equal to a preset threshold value.
If not, go to step S403.
If yes, go to S404.
For example, the preset threshold may be 70%, 80%, etc., and in an actual application process, the preset threshold may be set according to actual needs.
S403, the network device determines the scheduling resource of the first terminal device in the cell resource of the first cell.
The network device may determine unused resources of the cell resources as scheduled resources for the first terminal device.
S404, the network equipment determines the scheduling resource of the first terminal equipment in the preemptible resource of the first cell.
The preemptible resource of the first cell refers to a resource in another cell that can be used by the terminal device in the first cell. For example, the preemptible resource of the first cell may be part or all of the cell resources of the second cell. The first cell and the second cell are resource sharing cells.
Optionally, the core network corresponding to the first cell is different from the core network corresponding to the second cell. For example, the core network corresponding to the first cell is a first core network, and the core network corresponding to the second cell is a second core network. For example, the network (first core network) corresponding to the first cell is a first dedicated trunking network, and the network (second core network) corresponding to the second cell is a second dedicated trunking network; or, the network (first core network) corresponding to the first cell is an air wireless network, and the network (second core network) corresponding to the second cell is a ground wireless network.
For example, the first private clustered network may be a Broadband Trunking Communication (B-trunk) clustered network, and the second private clustered network may be a 3rd Generation Partnership Project (3 GPP) clustered network.
Optionally, the network device may generate the resource configuration information in advance, and determine the scheduling resource of the terminal device according to the resource configuration information.
Optionally, the resource configuration information may include the following form:
in a first form: the network device may generate resource configuration information corresponding to each cell.
In this case, the resource configuration information corresponding to each cell may include a cell resource of the cell, and a terminal device in the cell may preempt the preemptible resource. The preemptible resource may be a resource in one other cell or resources in multiple other cells, and when two cells share the resource, the preemptible resource may be a resource in one other cell, and when multiple (greater than two) cells share the resource, the preemptible resource may be a resource in multiple other cells. For example, when cell 1, cell 2, and cell 3 share resources, then the preemptible resources in cell 1 may include resources in cell 2 and resources in cell 3.
Further, the configuration information may further include a priority of the cell resource and a priority of the preemptible resource, where the priority of the cell resource is greater than the priority of the preemptible resource.
For example, the resource configuration information corresponding to cell 1 may be as shown in table 1:
TABLE 1
Referring to table 1, the resource configuration information of the cell 1 includes cell resources, a preemptible resource 1, a preemptible resource 2, and priorities of the resources. In an actual application process, the network device preferentially configures resources in the cell resources to the terminal device in the cell 1, and when the resources in the cell resources are relatively tight (for example, the resource occupancy rate is relatively high, or the remaining resources are relatively small), the preemptible resource 1 or the preemptible resource 2 may be configured for the terminal device in the cell 1.
In a second form: the network device generates resource configuration information for a plurality of cells.
In this case, the plurality of cells refer to cells that can share resources. The resource configuration information includes a plurality of resources and a cell identifier corresponding to each resource, where the resource can be used by the terminal device in the cell indicated by the cell identifier corresponding to the resource.
For example, assuming that 2 cells (cell 1 and cell 2) share resources, the resource configuration information of cell 1 and cell 2 may be as shown in table 2:
TABLE 2
Referring to table 2, resources that can be used by cell 1 and cell 2 include resource 1, resource 2, resource 3, and resource 4. Wherein resource 1 and resource 2 are configured as cell resources of cell 1, and resource 2 is also configured as preemptible resources, which can be used by terminal devices in cell 2. Resources 3 and 4 are configured as cell resources for cell 2, and resource 4 is also configured as a preemptible resource that can be used by terminal devices in cell 1.
It should be noted that, the above tables 1 to 2 only illustrate the resource configuration information in an exemplary form, and are not limited to the form of the resource configuration information and the included content, and in an actual application process, the resource configuration information may be set according to actual needs, which is not specifically limited in the embodiment of the present invention.
In an actual application process, the network device may query the preemptible resource of the first cell in the resource configuration information, and determine the scheduling resource of the first terminal device in the preemptible resource.
After the network device determines to obtain the scheduling resource of the first terminal device, the network device may send the indication information for indicating the scheduling resource to the first terminal device, so that the first terminal device sends information to the core network on the scheduling resource. The indication information may be an identification of the scheduled resource.
Optionally, after the first terminal device acquires the scheduling resource allocated to the first terminal device by the network device, the first terminal device may send a request message to the network device through the scheduling resource, where the request message is used to request to access the first core network. After the network device receives the request message, the network device accesses the first terminal device to the first core network through a wireless access point sharing mode (RAN sharing) according to the request message.
In the resource scheduling method provided in the embodiment of the present invention, when the network device schedules resources for a first network device in a first cell, the network device obtains the resource occupancy rate of the cell resources of the first cell, and when the resource occupancy rate of the cell resources of the first cell is greater than or equal to a preset threshold, the network device determines the scheduling resources of the first terminal device in the preemptible resources of the first cell. In the above process, when the resource occupancy rate of the cell resource of the first cell is high, the network device may schedule the resource in another cell for the terminal device in the first cell, so as to improve the resource utilization rate.
On the basis of any of the above embodiments, the resource scheduling method shown in the above embodiments will be described below with reference to fig. 5.
Fig. 5 is a schematic diagram of resource scheduling according to an embodiment of the present invention. Please refer to fig. 5, which includes a core network 1, a core network 2, a base station, a Sub Frequency (SF) SF1 cell, and an SF cell 2. The identity of core Network 1 is Public Land Mobile Network (PLMN) ID1, and the identity of core Network 2 is PLMN ID 2. The SF1 cell corresponds to core network 1 and the SF2 cell corresponds to core network 2. The SF1 cell and the SF2 cell are cells that serve the same base station.
The cell resource size of the SF1 cell is SF1, the cell resource of the SF1 cell is referred to as resource SF1 hereinafter, the cell resource size of the SF2 cell is SF2 hereinafter, and the cell resource of the SF2 cell is referred to as resource SF2 hereinafter, where preemptible resources exist in the cell resource of the SF1 cell, and the preemptible resources are: SF 1-Resource Block (RB) 2, which is hereinafter referred to as Resource SF1-RB 2. Preemptible resources exist in cell resources of the SF2 cell, and the size of the preemptible resources is: SF2-RB1, hereinafter referred to as resources SF2-RB 1.
For a terminal device in a SF1 cell, the amount of resources that can be used is: SF1+ (SF2-RB 1). For a terminal device in a SF2 cell, the amount of resources that can be used is: SF2+ (SF1-RB 2).
In an actual application process, when a terminal device in an SF1 cell requests to access a core network 1 through a base station, the base station first determines whether a resource utilization rate of a cell resource of the SF1 cell is greater than a preset threshold, if not, the base station determines a scheduling resource for the terminal device in a resource SF1, and allocates the scheduling resource to the terminal device, so that the terminal device accesses the core network 1 through the scheduling resource, for example, the base station may route the terminal device to the core network 1 through a RAN sharing manner. If so, the base station may determine the scheduling resource of the terminal device in the resources SF2-RB1 and allocate the scheduling resource to the terminal device, so that the terminal device accesses the core network 1 through the scheduling resource.
It should be noted that the resource scheduling manner of the base station for the terminal device in the SF2 cell is similar to the resource scheduling manner of the base station for the terminal device in the SF1 cell, and is not described here again.
In the above process, when there are more resources in the SF1 cell, the base station may determine the scheduled resources for the terminal devices in the SF1 cell in resource SF1, and when there are fewer resources in the SF1 cell, the base station may determine the scheduled resources for the terminal devices in the SF1 cell in resource SF2-RB1, so that the utilization rate of the resources is higher.
For example, in the field of public security, limited spectrum resources of clients are decomposed into sub-spectrum resources, cells corresponding to different PLMN IDs are respectively established on the sub-spectrum resources, and according to the number of terminals to which the different PLMN IDs belong and the service conditions, a PLMN ID-based sub-spectrum resource and a cross-subcarrier sharing strategy are defined. The RAN Sharing characteristics shared by other PLMN IDs are opened and wireless shared resources shared by other PLMN IDs are set for subcarrier frequency spectrums shared by the cross PLMN IDs, so that the distribution and scheduling of the cross-carrier wireless resources based on the PLMN IDs can be realized under the condition of supporting different departments to establish independent wireless private networks, the dynamic Sharing of the wireless resources between different private networks and the PLMN IDs is realized, emergency scenes or major security scenes are met, the wireless resource requirements of burst services are met, and the utilization rate of the wireless frequency spectrums is improved.
