With the continuous development of network technology, the network requirements of diversified industry applications (i.e. private network services of operators) are gradually increased, so that the network requirements for the private network services of the operators become an important development direction in 5G network deployment. The network slicing technology (also referred to as hard slicing technology) of the 5G base station can greatly ensure the service quality and security of the private network service, and therefore becomes an indispensable deployment content of the 5G base station.

The third generation partnership project (3 GPP) TS300 indicates that the base station on the wireless side can support different resource management and resource isolation techniques according to a service level agreement. A single wireless access point may support multiple slices and may freely apply the radio resource management policy of SLA (service level agreement) to each supported slice.

The wireless resource management mainly controls the configuration and the use of wireless resource slices, aims to solve the problem of resource allocation and isolation among the slices, ensures the network performance of the slices, and cannot influence the performance of other slices due to overload of a certain slice. From the two aspects of resource isolation and resource utilization, the wireless resource slices share the wireless resources according to the configuration rule mainly in a dynamic or static manner. For the dynamic mode, the wireless resource sharing between slices can be realized through a scheduling or competition mechanism. If each slice provides a resource request to the central scheduler by means of scheduling, the central scheduler allocates radio resources based on the requested resource amount, priority and overall load. If through the competition mode, each slice automatically acquires wireless resources according to the rules allowed to be defined, and the dynamic resource sharing allows the use optimization of the whole resources. For static approaches, i.e., by pre-configuring dedicated resources for operations, static resources share resources that are provided for slice guarantees.

The hard slicing technology is a static resource isolation technology, and isolation or slicing is performed on an RB; for example, within the same base station, different RBs are divided by cell, bwp (bandwidth part). The hard slicing technology fully ensures the bandwidth requirement of private network service, and ensures the wireless network performance facing industry users in a mode of resource exclusive sharing in a certain range. On the basis of QCI (QoS class identifier) scheduling, a layer of air interface resources are isolated, and certain air interface resources are reserved statically or semi-statically for private network services, so that the possibility of air interface resources of public network slices and private network slices is reduced, and the purpose of improving the performance and reliability of the private network is achieved.

Fig. 1 is a schematic diagram of hard-sliced radio resource allocation provided in an embodiment of the present application, as shown in fig. 1, for example, operator a includes one public network service and two private network services, where the radio resource of operator a is 100M bandwidth, and 273RB, the radio resource of operator a may be allocated to the public network service and each private network service as needed. Illustratively, fig. 1 reserves X% of RBs for private network service 1, reserves Y% of RBs for private network service 2, and shares the remaining RBs with public network service.

The existing 5G base station adopts 192-element multi-element base stations, so that the cost for building the base station is extremely high, the frequency band adopted by the 5G base station is 3.5GHz, and the coverage range is obviously smaller than that of the base station with the frequency band below 2GHz, so that the number of stations in unit area is multiplied. In summary, the high cost of base stations and the intensive number of base stations will lead to exponential increase of the cost, thereby causing huge pressure on the operators, so that the operators have now searched for a deployment scheme (i.e. shared base stations) in which multiple operators share the same base station, and several types of shared base stations and deployment scenarios are provided below.

The method for setting the shared base station according to the carrier wave can be divided into: a shared carrier base station type, an independent carrier base station type, an operator-based shared carrier base station type, a network type-based shared carrier base station type.

Shared carrier base station type: the shared base station communicates with the public network service and the private network service of each operator network through a carrier. For example, a path of carrier may use PLMN (public land mobile network), APN (access point name), DNN (deep neural network), etc. to distinguish between public network traffic and private network traffic.

Independent carrier base station type: the shared base station distributes a carrier for public network service and private network service of each different operator respectively; the public network carrier may directly distinguish an operator to which the terminal belongs, and the private network carrier may distinguish private network services of different operators, but when one operator has multiple private network services, PLMN, APN, CNN (convolutional neural network), or the like may be used for distinguishing.

Operator-based shared carrier base station types: the shared base station distributes different carriers for different operators, namely, the carriers are distinguished by using frequency, and public network services and private network services under the carriers are distinguished by using PLMN, APN or CNN and the like.

Shared carrier base station type based on network type: the shared base station distributes 2 independent carriers for public network service and private network service, and different operators under the public network carrier adopt PLMN for distinguishing; and adopting PLMN, APN or CNN and the like to distinguish under the private network carrier.

The shared base station can be divided into: large capacity scenarios, multiple connection number scenarios, and integrated scenarios. By distinguishing different service scenes, the calculation complexity of the base station in the load balancing process can be effectively reduced, and the scheduling efficiency is improved.

Large-capacity scenes: and calculating the business proportion according to the business situation of a certain time period. For example, when big data traffic is dominant, a capacity-based configuration method is adopted.

Multiple connection number scenario: and calculating the business proportion according to the business situation of a certain time period. For example, when the number of Radio Resource Control (RRC) connections is dominant, a configuration method based on the number of users is adopted.

And (3) comprehensive scene: for scenes without large capacity and scenes with multiple connections, a configuration method of comprehensive capacity and user number is used.

Based on the type and deployment scenario of the shared base station, the embodiment of the present application provides a method for configuring resource blocks of the type of the shared carrier base station in an integrated scenario, where a network device (i.e., the shared base station) receives multiple services sent from a terminal at a current time, determines a required number of resource blocks transmitted by multiple service links, and configures the resource blocks for the multiple services according to the requirements of the multiple services when the required number of resource blocks is less than or equal to the number of resource blocks provided by the network device; under the condition that the required number of the resource blocks is larger than the number of the resource blocks provided by the network equipment, the public network service shares the number of the resource blocks required by the public network service, and the resource blocks are configured for the private network service according to the preset QoS priority of the private network service, so that the utilization rate of carrier resources is improved.

In the 5G baseband processing unit, by adding different operators and identification modules of network types of different operators in a Control Plane (CP), the distinction between public network services and private network services of different operators to which the terminal belongs can be realized. Meanwhile, the 5G baseband processing unit connects different 5G core networks (e.g., a public network core network and a private network core network) by using a plurality of optical fibers.

The following describes in detail a method for configuring resource blocks provided in the embodiment of the present application with reference to the communication system shown in fig. 2.

The resource block configuration method provided by the embodiment of the present application is applied to a network device, for example, the network device shown in fig. 3. The network device supports a plurality of operator networks, each operator network in the plurality of operator networks being different; the network device communicates with public network services and private network services of each operator network through a carrier. Fig. 5 is a schematic flowchart of a configuration method of a resource block according to an embodiment of the present application, and as shown in fig. 5, the configuration method includes:

s201, a configuration device of a resource block receives a plurality of services sent by a terminal at the current time and determines the required number of the resource block.

The resource block requirement number is used for indicating the number of resource blocks required by the transmission of a plurality of service links.

Specifically, the terminal establishes a connection with a cell set under the network device, the cell includes a plurality of terminals, and the plurality of terminals send services to the network device, that is, the network device can receive a plurality of services sent by the plurality of terminals and determine the required number of resource blocks transmitted by a plurality of service links.

It should be noted that the traffic link transmission between the terminal and the network device includes uplink transmission and downlink transmission. The required number of resource blocks in the embodiment of the present application may include the number of resource blocks required in the transmission process of multiple service uplinks (hereinafter referred to as the required number of uplink resource blocks), the number of resource blocks required in the transmission process of multiple service downlinks (hereinafter referred to as the required number of downlink resource blocks), and the number of resource blocks required in the transmission process of multiple service uplinks and the transmission process of downlinks (that is, the required number of uplink resource blocks and the required number of downlink resource blocks).

S202, if the required number of the resource blocks is less than or equal to the number of the resource blocks provided by the network equipment, the configuration device of the resource blocks configures the resource blocks for a plurality of services according to the requirements of the plurality of services; otherwise, the public network service shares the number of resource blocks required by the public network service, and the configuration device of the resource blocks configures the resource blocks for the private network service according to the preset QoS priority of the private network service.

For example, the priority of different services may be calculated according to the priority level in the 5G QoS characteristics associated with the 5QI, i.e., the 5QI is analyzed to obtain the priority level, and then the priority calculation of different services is performed. It is to be understood that the 5QI is a scalar for reference to evaluate 5G QoS characteristics, and the 5G QoS characteristics associated with the 5QI are shown in table 1:

TABLE 1

The following is a 5QI Table that has been completed by 3GPP, i.e. a standardized 5QI mapping Table, as shown in Table 2, and Table 2 is a 5QI mapping relation Table standardized by TS23.501 Table 5.7.4-1.

TABLE 2

For convenience of understanding, the preset QoS priority in the embodiment of the present application may adopt the default priority shown in table 2, and is not described herein again.

When the required number of resource blocks includes the required number of uplink resource blocks, the resource block allocation device is configured according to the required number of uplink resource blocks (denoted by symbol:)

) And the number of uplink resource blocks (labeled as

) Judging; when the required number of resource blocks includes the required number of downlink resource blocks, the resource block allocation device allocates the resource blocks according to the required number of downlink resource blocks (denoted by symbol

) And the number of downlink resource blocks (labeled as

) Judging; under the condition that the required number of the resource blocks comprises the required number of the uplink resource blocks and the required number of the downlink resource blocks, the configuration device of the resource blocks judges according to the required number of the uplink resource blocks, the required number of the downlink resource blocks, and the number of the uplink resource blocks and the number of the downlink resource blocks provided by the network equipment.

For example, if

Or

Or

And is

And if so, the resource block configuration device configures the resource blocks for the plurality of services according to the requirements of the plurality of services.

It should be noted that, in the embodiments of the present application, the resource block requirement number includes an uplink resource block requirement number and a downlink resource block requirement number, which are all exemplified, that is, all service link transmissions include uplink transmission and downlink transmission, that is, the configuration device of the resource block determines according to the uplink resource block requirement number, the downlink resource block requirement number, and the number of uplink resource blocks and the number of downlink resource blocks provided by the network device.

Based on the above determination result, when the required number of resource blocks of all services is less than or equal to the maximum required number of resource blocks that can be provided by the network device, the required number of resource blocks of all services can be satisfied by the number of resource blocks of the network device, and therefore, the network device can allocate how many resource blocks to each service as many resource blocks are required by each service in all services. Under the condition that the required number of the resource blocks of all services is larger than the maximum number of the resource blocks which can be provided by the network equipment, the configuration device of the resource blocks calculates the number of the resource blocks which are required by all public network service link transmission, and calculates the number of the resource blocks which can be distributed to all private network services.

Illustratively, the number of resource blocks required for all public network traffic link transmissions satisfies the following formula:

in the formula (1), the acid-base catalyst,

the maximum number of resource blocks provided for all public network traffic uplink transmissions by the network device,

indicating the number of resource blocks that the network device can allocate to all public network traffic uplink transmissions at the current time,

representing the number of resource blocks required by the uplink transmission of all public network services;

representing the maximum number of resource blocks that the network device provides for downlink transmission of all public network traffic,

indicating the number of resource blocks that the network device can allocate to all public network traffic downlink transmissions at the current time,

indicating the number of resource blocks required for all public network traffic downlink transmissions.

The configuration device of the resource block can allocate the number of the resource blocks to all the private network services to satisfy the following formula:

in the formula (2), the reaction mixture is,

for the maximum number of uplink resource blocks that the network device can provide,

the number of resource blocks required for all public network traffic uplink transmissions,

the number of uplink resource blocks which can be allocated to all private network services for the network equipment;

for the maximum number of downlink resource blocks that can be provided by the network device,

the number of resource blocks required for all public network traffic downlink transmissions,

the number of resource blocks that a network device can allocate to downlink transmission of all private network traffic.

For example, the maximum number of uplink resource blocks that the network device can provide satisfies the following formula:

in the formula (3), the reaction mixture is,

maximum number of downlink resource blocks, RBs, that can be increased for a network device_maxMaximum number of resource blocks, P, that can be provided for a network device_ULIs the ratio of the number of uplink resource blocks in the frame structure at the current moment.

Specifically, when the resource block requirement number of all services is greater than the maximum resource block number that can be provided by the network device, the resource block number required for transmission of all public network service links is first guaranteed, that is, the resource block number required for transmission of all public network service links calculated according to the above formula (1), (i.e., (resource block number required for transmission of all public network service links: (1)

And

) And all public network services share the number of resource blocks required by the transmission of the public network service link.

For example, the sharing allocation is performed according to the preset QoS priority of all the public network services, that is, the high-priority public network service uses the number of resource blocks required by all the public network services first, and then the low-priority public network service uses the number of resource blocks required by all the public network services again.

In addition, the number of resource blocks that can be allocated to all private network services by the network device calculated according to the above equation (2) (2)

And

) And sequentially distributing resource blocks to the private network services according to the preset QoS priority of all the private network services. However, if the number of resource blocks allocated to the private network service reaches 70% of the number of resource blocks that can be allocated to all the private network services by the network device, the allocation of resource blocks to the private network service with low priority is stopped, and the remaining private network services with low priority share the remaining 30% of the number of resource blocks.

The configuration method of the resource block provided by the embodiment of the application is applied to network equipment, the network equipment can support a plurality of operator networks, and each operator network in the plurality of operator networks is different; the network equipment communicates with public network services and private network services of each operator network through a path of carrier, and when the network equipment receives a plurality of services sent by a terminal at the current moment, the network equipment can determine the resource block demand number of all the services, namely determine the resource block number required by all the service link transmission; under the condition that the required number of the resource blocks is less than or equal to the number of the resource blocks provided by the network equipment, the network equipment configures the resource blocks for a plurality of services according to the requirements of the plurality of services, under the condition that the required number of the resource blocks is greater than the number of the resource blocks provided by the network equipment, the network equipment does not configure the resource blocks for the public network service independently, all the public network services share the number of the resource blocks required by the public network service, and the network equipment configures the resource blocks for the private network service according to the preset QoS priority of the private network service, so that the resource utilization rate of the network equipment under the carrier wave is improved.

Optionally, as shown in fig. 6, before determining the number of resource block requirements, the configuration method further includes:

s201a, the resource block configuration apparatus obtains service identifiers of multiple services, and determines service attributes of the multiple services.

The service attribute includes a public network service of the operator network or a private network service of the operator network.

Illustratively, the service identity includes PLMN, DNN (or ID of network slice).

Specifically, the PLMN is extracted from PLMN information of broadcast signaling SIB1 in a plurality of services to be accessed to the network device, and DNNs of the plurality of services are extracted from PDU session attribute request signaling.

It should be noted that, the PLMN is used to distinguish the operator network to which the service belongs, and the DNN is used to distinguish the service as a public network service or a private network service.

For example, when the service identifier of the service includes plmn (a) and does not include DNN, the service is a public network service of the operator network a; when the service identifier of the service includes plmn (B) and does not include DNN, the service is a public network service of the operator network B; when the service identifier of the service includes plmn (a) and dnn (i), the service is private network service i of operator network a; when the service identifier of the service includes plmn (B) and dnn (j), the service is private network service j of operator network B.

It should be noted that an operator network only has one public network service, but may have one or more private network services. In addition, it is to be noted that, if an operator determines that private network services are not to be distinguished by DNN, private network services may be distinguished by using a slice ID, that is, a configuration method of a resource block based on a PLMN and a slice ID may be implemented, and if private network services are to be distinguished by DNN and a slice ID at the same time, a service QoS added value under a slice ID needs to be added on the basis of the configuration method of a resource block provided in the embodiment of the present application, which is not described in detail herein.

Specifically, the resource block configuration device determines the number of resource blocks required for transmission of the public network service link of the operator and the number of resource blocks required for transmission of the private network service link of the operator, and combines the number of resource blocks required for transmission of the public network service link of the operator and the number of resource blocks required for transmission of the private network service link of the operator to obtain the resource block requirement number of multiple services.

In the embodiment of the application, the configuration device of the resource block can determine the service attributes of the services according to the service identifiers of the services, that is, determine whether the services are the public network service of the operator network or the private network service of the operator network, and calculate the resource block demand number of all the services according to the service attributes, so that the configuration device of the resource block can respectively configure the resource block for the public network service and the private network service according to the resource block demand number, which is beneficial to improving the utilization rate of carrier resources.

Optionally, the multiple services include public network services of N operator networks and M private network services of N operator networks, where N is greater than or equal to 2, M is greater than or equal to 2, and M is greater than or equal to N; fig. 7 is a flowchart illustrating a method for configuring a resource block according to an embodiment of the present application, and as shown in fig. 7, S201 may be replaced by S2011-S2013.

S2011, the configuration device of the resource block determines N first resource block allocation values; the first resource block allocation value is used for indicating the number of resource blocks required by public network service link transmission of the operator network.

For example, among the N first resource block allocation values determined by the resource block configuration device, each first resource block allocation value may be as shown in table 3 below:

TABLE 3

S2012, the resource block configuration device determines M second resource block allocation values; wherein the second resource block allocation value is used to indicate the number of resource blocks required for private network service link transmission of the operator network.

For example, among the M second resource block allocation values determined by the resource block configuration device, each second resource block allocation value may be as shown in table 4 below:

TABLE 4

S2013, the resource block configuration device determines the resource block demand number according to the N first resource block allocation values and the M second resource block allocation values.

Specifically, N first resource block allocation values of public network services of all operator networks and M second resource block allocation values of all private network services of all operator networks are combined, that is, the N first resource block allocation values and the M second resource block allocation values are subjected to weighting processing to determine the resource block demand number.

Illustratively, the resource block requirement number is determined to satisfy the following formula:

in the formula (4), the reaction mixture is,

the number of resource block requirements for all traffic uplink transmissions,

when the uplink transmission is carried out, the nth first resource block is distributed with a value N which is more than or equal to 1 and less than or equal to N;

representing the sum of the N first resource block allocation values when uplink transmission is performed;

representing the sum of the M second resource block allocation values for the N operator networks for downlink transmission.

In the embodiment of the application, the resource block configuration device performs weighting processing on the determined number of the resource blocks required by the transmission of the public network service links of the N operator networks and the number of the resource blocks required by the transmission of the M private network service links of the N operator networks to obtain the required number of the resource blocks, so that the resource blocks can be reasonably configured for the public network service and the private network service according to the required number of the resource blocks compared with the number of the resource blocks provided by the network equipment, and the utilization rate of carrier resources can be improved under the condition of ensuring the service transmission performance.

Optionally, as shown in fig. 8, for each first resource block allocation value, the following operations are performed to determine N first resource block allocation values. Specifically, the following operations include: s2011a, S2011b and S2011 c.

S2011b, the configuration device of the resource block determines the resource block reservation limit of the public network service of the first operator network; the public network service of the first operator network is any one of the public network services of the N operator networks; the resource block reserved amount is used for indicating a coefficient of the number of resource blocks reserved for the next moment of the current moment of the public network service of the first operator network.

S2011c, the resource block configuration device determines N first resource block allocation values according to the number of resource blocks required for the first service link transmission and the resource block reservation quota of the public network service of the first operator network.

Illustratively, the first resource block allocation value satisfies the following formula:

in the formula (5), the reaction mixture is,

when the resource allocation is downlink transmission, the nth first resource block is allocated, wherein i is more than or equal to 1 and less than or equal to N + M, and N is more than or equal to 1 and less than or equal to N.

Optionally, as shown in fig. 8, for each second resource block allocation value, the following operations are performed to determine M second resource block allocation values. Specifically, the following operations include: s2012a, S2012b and S2012 c.

The preset capacity parameter is used for indicating the proportion of the service capacity to the total service in a preset time period, and the preset user number dependence parameter is used for indicating the proportion of the user number to the total service in the preset time period.

Specifically, the service distribution condition in the planned deployment area for a period of time may be selected for analysis, and the preset capacity dependent parameter and the preset user dependent parameter are obtained, so that the application range of the resource block configuration method provided by the embodiment of the present application is defined.

For example, the preset time period may select information of the public network service, the traffic of the private network service, and the number of users of the private network service of the operator network of the deployment area every hour in a busy hour period of a working day (e.g., tuesday) and a non-working day (e.g., sunday) in two consecutive weeks. Assuming that the operator network includes an operator network a and an operator network B, the information extracted from the public network service and the private network service of the operator network in the deployment area is shown in table 5 below:

TABLE 5

In table 5, RRC (range controlled communication, user connection number) indicates the RRC number (including the RRC number with service transmission and the RCC number without service transmission) for the network device to establish connection with the cell set under the network device; the number of RRC connections with data transfer indicates the number of RRC connections (including only the number of RRC connections with traffic transfer) that the network device establishes a connection with a cell under the network device.

And calculating based on the acquired capacity and the number of users, and determining a preset capacity dependence parameter and a preset user dependence parameter. First, the total hours of a preset time period is determined, that is, the total time H of busy hours in two consecutive weeks, a working day of a day and a non-working day of a day is determined, and for example, H satisfies the following formula:

wherein the content of the first and second substances,

S1B, the configuration device of the resource block determines the number of basic resource blocks needed by the transmission of the first service link.

Specifically, the number of basic resource blocks required for transmission of the first service link may be calculated according to the relevant parameter of the first service. The relevant parameters of the first service comprise: reference Signal Receiving Power (RSRP), throughput (throughput), Channel Quality Indicator (CQI), block error rate (Bler), and a preset QoS priority.

Specifically, 5QI information, service capacity information, RSRP information, and the like of the service may be extracted from the SMF-UDM Registration signaling.

Illustratively, the calculation of the basic resource block number includes two kinds of capacity-based resource block number calculation and signaling-based resource block number calculation.

The calculation of the number of resource blocks based on capacity may be via RSRP, uplink Throughput (TUL), downlink Throughput (TDL) at the time of transmission of the first traffic link.

Illustratively, the capacity-based number of resource blocks satisfies the following formula:

in the formula (7), the reaction mixture is,

the number of resource blocks based on capacity when transmitting for the ith service uplink; TUL_iFor uplink throughput, RSRP, of ith traffic_iThe reference signal received power transmitted for the ith traffic link,

the number of resource blocks based on capacity when the downlink is transmitted for the ith service; TDL_iThe downlink throughput of the ith service is shown, wherein i is more than or equal to 1 and less than or equal to N + M.

As an example, the RSRP and throughput information of each sampling point can be recorded by performing drive test on a scenario where resource block configuration is to be performed, as shown in table 6 below:

class of acquisition	RSRP	Uplink throughput	Downlink throughput
				Service 1	RSRP1	TUL1	TDL1
Service 2	RSRP2	TUL2	TDL2
				……	……	……	……
Service i	RSRPi	TULi	TDLi

TABLE 6

It should be noted that independent drive tests and evaluations are required for different scenarios. Taking a 5G high-speed rail deployment scenario as an example, and the service transmission link in the scenario is a downlink transmission link, a fitting formula and a fitting schematic diagram are given. Fig. 10 is a schematic fitting diagram, where fig. 10 is a schematic fitting diagram of RB-RSRP-throughput in a high-speed rail scenario provided by the embodiment of the present application; further, the fitting formula is as follows:

RB＝p00+p10×TDL+p01×RSRP+p20×TDL²+p11×TDL×RSRP+p30×TDL³+p21×TDL²×RSRP

wherein, p00 ═ 359.8(311.7,407.9), p01 ═ 3.029(2.421,3.636), p10 ═ 0.2604(-0.9436,0.4227), p20 ═ 0.001386(-0.003572,0.0007992), p11 ═ 0.02031(-0.02823, -0.01239), p30 ═ 3.696e-06(1.72e-06,5.673e-06), p21 ═ 3.223e-05(1.347e-05,5.099 e-05).

According to the fitting formula, the fitting performance under the scene can be obtained. The fitting performance includes: SSE (and variance), R-square (determination coefficient), Adjusted R-square (correction decision coefficient), and RMSE (root mean square). For example, an SSE of 5.163e +04, an R-square of 0.9128, an Adjusted R-square of 0.9098, and an RMSE of 17.13.

Since a PDCCH (physical downlink control channel) is used to allocate the number of resource blocks of the downlink traffic channel, the number of resource blocks of the downlink traffic channel may be calculated by a CCE (control channel element) of the PDCCH based on the calculation of the number of resource blocks of the signaling.

The PDCCH is mainly used for transmitting downlink control information and UL Grant, so that the terminal correctly receives a PDSCH (physical downlink shared channel) and allocates uplink resources for a PUSCH (physical uplink shared channel). Here, the allocation unit is a CCE (e.g., 1CCE ═ 6REG ═ 72RE, 1REG ═ 1OFDM symbol × 12subcarrier ═ 12 RE). For a PDCCH, the PDCCH consists of one or more CCEs, and the number of CCEs allocated varies according to aggregation levels, and the aggregation levels supported by the PDCCH are shown in table 7:

grade of polymerization	Number of CCEs
		1	1
2	2
		4	4
8	8
		16	16

TABLE 7

Based on CCE aggregation conditions of services at different positions, the scheduling capability of the PDCCH can be calculated and converted into the number of resource blocks of a downlink service channel.

The CCE aggregation level is related to the location of the terminal, and therefore may be calculated by CQI, Bler, QoS priority, RSRP, and the like, and for example, the CCE aggregation level satisfies the following formula: CCE ═ f (CQI, Bler, PL, RSRP); wherein PL is a QoS priority (priority level).

It should be noted that the calculation methods of different operators are not consistent, and may be expressed by the above formula, and the calculation methods of the operators are replaced in actual operation.

In the 5G communication system, the CCE aggregation levels and the space levels corresponding to different network locations are different, and therefore, the number of resource blocks of different services per slot (slot) is calculated according to the CCE aggregation levels and the space levels at different locations. Illustratively, the number of signaling-based resource blocks satisfies the following formula:

in formula (8), CCE_iIndicating the CCE aggregation level of the ith service,

the number of layers is the number of the air separation layers,

contribution degree for ith service;

In addition, under the condition that the carriers are completely shared, the public network service and the private network service of different operators are borne under the same carrier, so in order to consider the condition of the QoS priority of the operator as a whole and the QoS priority (or the slice ID priority) of the private network service, the embodiment of the application provides that the resource block reserved quota is calculated according to the two levels of the public network service and the private network service of the operator respectively.

In the embodiment of the application, the QoS priority corresponding to a certain percentage of CDF curves of different QoS priority sets is adopted as a comprehensive condition for measuring the QoS priorities of a plurality of services. Fig. 11 is a CDF curve of a QoS priority distribution provided by an embodiment of the present application, as shown in fig. 11, for example, when the CDF is 90%, the corresponding QoS value is 78.

Optionally, the resource block reservation quota of the public network service of the first operator network is related to the QoS value of the public network service of the first operator network and the QoS values of the public network services of the N operator networks.

Specifically, the resource block reservation quota of the public network service of the first operator network is a ratio of a QoS value corresponding to the coverage ratio quantile of the public network service QoS CDF curve of the first operator network to a QoS value corresponding to the coverage ratio quantile of all the service QoS CDF curves. Wherein, the coverage ratio can be set according to specific needs, such as 90%. It should be noted that the coverage ratio of the public network service cannot be greater than that of the private network service.

Optionally, the resource block reserved amount of the first private network service of the N operator networks is related to the QoS value of the public network service of the first operator network, the QoS value of the public network service of the N operator networks, the QoS value of the first private network service, and the QoS value of the M private network services.

Specifically, the resource block reservation quota of the first private network service is a product of a QoS value corresponding to the public network service QoS CDF curve coverage ratio quantile of the first operator network and a QoS value corresponding to the all-service QoS CDF curve coverage ratio quantile, and a QoS value corresponding to the QoS CDF curve coverage ratio quantile of the first private network service and a QoS value corresponding to the all-private network service QoS CDF curve coverage ratio quantile.

Illustratively, through a QoS CDF curve of QoS priority distribution of network devices under different scenarios, the following formula can be obtained:

and expressing the QoS value of the public network service of the nth operator network, wherein N is more than or equal to 1 and less than or equal to N.

The QoS value of the mth private network service under N operator networks is represented; wherein M is more than or equal to 1 and less than or equal to M.

Expressing the QoS value of public network service and private network service under the nth operator network; wherein N is more than or equal to 1 and less than or equal to N.

Representing the QoS values of public network traffic under all operator networks.

Represents the QoS value of all private network traffic under all operator networks.

The QoS values represent all public network traffic and all private network traffic under all operator networks.

And covering a proportional quantile by a QoS CDF curve corresponding to the QoS value of the public network service of the nth operator network.

And covering a proportional quantile by a QoS CDF curve corresponding to the QoS value of the mth private network service.

And the QoS CDF curves corresponding to the QoS values representing all private network services cover the proportional quantile.

Wherein the content of the first and second substances,

the QoS CDF curve corresponding to the QoS value representing the public network service of the nth operator network covers the proportional quantile,

the QoS CDF curves corresponding to the QoS values representing all services cover the proportional quantiles,

resource block reservations representing public network traffic of the nth operator network.

Wherein the content of the first and second substances,

the QoS CDF curve corresponding to the QoS value representing the mth private network service covers the proportional quantile,

the QoS CDF curve corresponding to the QoS value representing all private network services covers a proportional quantile,

and resource block reserved quota for the mth private network service.

The resource block reservation quota of the public network service of the first operator and the resource block reservation quota of the first private network service meet the following formula:

in the formula (10), Add^PUA quota is reserved for resource blocks of the first operator's public network traffic,

reserving a quota for a resource block of a public network service of the nth operator network; add (d)^PRA quota is reserved for resource blocks of the first private network service,

and reserving a quota for the resource block of the mth private network service.

In the embodiment of the application, the network device reasonably configures the resource blocks for the public network service and the private network service of the operator at the current moment by determining the resource block reservation limit of the public network service of the first operator and the resource block reservation limit of the first private network service, namely, on the premise of ensuring the number of the resource blocks required by the link transmission of the public network service and the private network service of the operator at the current moment, a part of the resource blocks are reserved for the next moment at the current moment, so that the power consumption is reduced, and the utilization rate of carrier resources is improved.
