Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
With the continuous evolution of networks, industry users' network demands have become an important deployment requirement for the fifth generation mobile communication technology (5-generation, 5G). However, the 5G base station generally adopts a multi-array device configuration such as 192 arrays, which results in extremely high manufacturing cost of the 5G base station. In addition, the frequency band adopted by 5G is 3.5GHz, and the coverage range is obviously smaller than the base station of the frequency band below 2GHz, so that the number of stations in unit area is increased by times. Thus, the high base station costs and the dense number of base stations will lead to an exponential increase in operator costs.
The presence of the co-established shared base station reduces the cost of the base station which is required to be input by operators, and also meets the requirements of the operators for deploying public network services. Currently, a base station of a single operator usually carries public network service and private network service, or a plurality of operators commonly build and share the base station to carry public network service. It can be seen that the co-established shared base station is not capable of supporting both public network services and private network services of different operators simultaneously. The scheduling of carrier resources in public network service and private network service of different operators by shared carriers is further not supported.
In order to solve the above problems, the present application provides a shared carrier base station that synchronously supports public network services and private network services of different operators. The shared carrier base station adopts a single carrier mode, firstly, data of different operators are modulated on the same carrier by using a baseband processing unit, and then uplink data and downlink data are respectively combined together by using a radio frequency unit and output to the same antenna unit. The baseband processing unit of the shared carrier base station is connected with different 5G core networks (such as a public network core network and a private network core network of an operator) by adopting a plurality of optical fibers, and is used for interaction between the shared carrier base station and the core network. Therefore, in the shared carrier base station, one carrier can be utilized to carry public network services and private network services of different operators.
The carrier resource scheduling method of the embodiment is applied to the scene of carrier resource scheduling of the service performed by the shared carrier base station. The carrier resource scheduling device acquires network information of each service flow in at least one service flow and dependent parameters of a target area. And then, executing first judgment on the network information of each service flow to obtain the network type of each service flow, and determining the priority parameter of each service flow according to the dependent parameters and the network information. And finally, carrying out carrier resource scheduling on at least one service flow according to the priority parameter and the network type of each service flow. In this way, the method for scheduling carrier resources in the public network service and the private network service of different operators for sharing the carrier is provided, so that the requirement that a plurality of operators simultaneously deploy the public network service and the private network service in the shared carrier base station is met, and the application range of the shared carrier base station is widened.

After the application scenario and the implementation environment of the embodiment of the present application are introduced, the carrier resource scheduling method provided by the embodiment of the present application is described below by referring to fig. 3 in conjunction with the carrier resource scheduling device shown in fig. 2.
Fig. 3 is a flow chart of a carrier resource scheduling method according to an embodiment of the present application, where the carrier resource scheduling method is applied to a shared carrier base station, and the shared carrier base station covers a target area. Referring to fig. 3, the carrier resource scheduling method includes the following steps.
301. The carrier resource scheduling device acquires network information of each service flow in at least one service flow and dependent parameters of a target area.
Wherein the dependent parameters include a capacity dependent parameter and a user number dependent parameter.
Specifically, the method for the carrier resource scheduling device to obtain the dependent parameters of the target area includes the following step 301a.
301a, a carrier resource scheduling device firstly acquires a first number and a second number of target areas in a preset time period. Wherein the preset time period comprises at least one hour; the first number is the number of hours, in at least one hour, for which the amount of transmitted data is greater than a first threshold; the second number is the number of hours, of at least one hour, for which the RRC connection number is greater than the second threshold. The preset time period is preset, for example, may be a default value, or may be a numerical value written by a relevant person according to an actual situation. For another example, the preset time period is 1 day of work and one day of non-work in two consecutive weeks.
Specifically, the carrier resource scheduling device collects information such as network type and radio resource control protocol (radio resource control, RRC) connection number of the service accessed to the shared carrier base station service within a preset time period. For example, the carrier resource scheduling device collects the network type of the service, the average capacity of the service, the highest capacity of the service, the average RRC connection number of the service, the maximum RRC connection number of the service, the average number of RRC connections with data transmission of the service, and the maximum number of RRC connections with data transmission of the service corresponding to each hour in 1 day of working day and 1 day of non-working day in busy hour period. As shown in table 1 below:
TABLE 1
And then, the carrier resource scheduling device determines the first quantity and the second quantity according to the network type of the service accessed in the shared carrier base station and the RRC connection number of the service. Specifically, if it is determined that the sum of the data volume of the public network service and the data volume of the private network service accessed in the shared carrier base station is greater than a first threshold in the first hour, the carrier resource scheduling device determines that the first hour is the dominant hour of the big data service, and adds one to the first number. And calculating all the acquisition hours by adopting the first number counting method, and accumulating to obtain a first number of numerical values. Wherein the first hour is any one of the collection hours; the first threshold may be a default value, or may be a value written by a related person according to an actual situation, for example, the related person determines the first threshold according to a sum of data volume of public network service and data volume of private network service accessed in the shared carrier base station in a first hour, and a ratio of the data volume to the total service capacity that can be accessed by the shared carrier base station.
If the sum of the average RRC connection number of the public network service accessed in the shared carrier base station and the average RRC connection number of the private network service is determined to be greater than the second threshold in the second hour, or the sum of the average RRC connection number of the public network service accessed in the shared carrier base station and the average RRC connection number of the private network service is determined to be greater than the second threshold, the carrier resource scheduling device determines that the second hour is the hour number of the dominant user, and is one added to the second number. And calculating all the acquisition hours by adopting the second number counting method, and accumulating to obtain the numerical value of the second number. Wherein the second hour is any one of the collection hours; the second threshold may be a default value, or may be a value written by a related person according to an actual situation, for example, the related person determines the second threshold according to a sum of an average RRC connection number of public network services accessed in the shared carrier base station and an average RRC connection number of private network services in a first hour, a ratio of the average RRC connection number of public network services accessed in the shared carrier base station to the total RRC connection number of private network services, or the related person determines the second threshold according to a ratio of the average RRC connection number of public network services accessed in the shared carrier base station to the average RRC connection number of private network services to the total RRC connection number of public network services connectable in the first hour.
Then, the carrier resource scheduling device calculates the user dependent parameter and the dependent parameter of the capacity target area according to the first number and the second number. Specifically, the capacity dependent parameter satisfies the formula
User number dependent parameters satisfy->
Wherein (1)>
Representing a first quantity, +.>
Representing a second number, Z T Representing capacity dependent parameters, Z R Indicating user number dependenceParameters.
Then, the carrier resource scheduling device judges whether load balancing is needed when carrier resource scheduling is performed. Specifically, the carrier resource scheduling device determines the total busy hour duration of the target area according to the acquired information such as the network type of the service accessed in the shared carrier base station, the RRC connection number of the service and the like. Specifically, the total busy time duration of the target area satisfies the formula h= Σ d ∑ i H i Wherein d represents the number of days of collection, H i Indicating the ith acquisition hour.
And then, the carrier resource scheduling device judges whether load balancing is needed when the carrier resource scheduling is carried out according to the total busy hour time length, the first quantity and the second quantity of the target area. Specifically, if it is determined that the ratio of the first number to the total duration of busy hours is smaller than the third threshold value, or the ratio of the second number to the total duration of busy hours is smaller than the fourth threshold value, load balancing is required when scheduling carrier resources. The third threshold may be a default value, or may be a numerical value written by a relevant person according to an actual situation. For example, the third threshold is 0.3. The fourth threshold value may be a default value, or may be a numerical value written by a relevant person according to an actual situation. For example, the fourth threshold is 0.3.
Finally, the carrier resource scheduling device acquires the network information of each service flow after determining that load balancing is required.
The network information of the service flow includes public land mobile network (public land mobile network, PLMN) of the service flow, data network name (data network name, DNN) of the service flow, service quality identifier (5G QoS identifier,5QI) of the service flow, capacity requirement of the service flow, RRC connection number with data transmission of the service flow, arrival time of the service flow and requirement duration of the service flow.
Specifically, the method for the carrier resource scheduling device to obtain the network information of each service flow in at least one service flow includes the following step 301b.
301b, the carrier resource scheduling device determines that the service terminal has a service access requirement, and obtains information such as a system information block (system information block type, SIB 1), a protocol data unit (protocol data unit, PDU) session establishment request (PDU session establishment request), a session management function (session management function, SMF) -unified data management function (unified data management, UDM) registration (SMF-UDM registration) of each service flow in at least one service flow. Then, the carrier resource scheduling device extracts the PLMN of the service flow from SIB1, extracts the DNN of the service flow from PDU session establishment request, and extracts 5QI of the service flow, capacity requirement of the service flow, RRC connection number with data transmission of the service flow, arrival time of the service flow, and required duration of the service flow from SMF-UDM registration. Wherein, 5QI of the traffic flow is a scalar for indexing 5G QoS characteristics, and in this application, the 5QI parameter is a priority level corresponding to the traffic flow in the 5G QoS characteristics. In the TS23.501 Table 5.7.4-1 protocol, there is a standardized 5QI mapping relationship, in the 5G QoS characteristics, the priority level indicates a resource scheduling priority between 5G QoS flows, and the parameter is used to distinguish QoS flows of one service terminal from QoS flows of different terminals, and the smaller the value of the priority level is, the higher the priority is.
302. The carrier resource scheduling device executes first judgment on the network information of each service flow to obtain the network type of each service flow.
Specifically, the first judgment is: if the PLMN of the first service flow is determined to correspond to the first operator and the DNN of the first service flow is empty, determining that the network type of the first service flow is the public network of the first operator. If the PLMN of the first service flow is determined to correspond to the second operator and the DNN of the first service flow corresponds to the first private network, determining that the network type of the first service flow is the first private network of the second operator. Wherein the first traffic flow is any traffic flow in the at least one traffic flow.
303. The carrier resource scheduling device determines the priority parameter of each service flow according to the dependent parameters and the network information.
Specifically, the carrier resource scheduling device executes a first operation on each service flow to obtain a priority parameter of each service flow.
The first operation is that: firstly, the carrier resource scheduling device calculates key parameters of the second service flow according to the capacity requirement of the second service flow, the RRC connection number with data transmission, the capacity dependent parameters and the user number dependent parameters of the target area. Wherein the second traffic flow is any traffic flow of the at least one traffic flow. Specifically, the key parameters of the second traffic flow satisfy the formula
Wherein Z is Ti Representing a capacity dependent parameter of the target area, Z Ri User-dependent parameters, K, representing target areas i Representing key parameters of the second traffic flow, T i Representing capacity requirement of the second traffic flow, RRC i RRC connection number indicating second traffic flow, RSC i RRC connection number with data transmission, T, representing second traffic flow 1 ,T 2 ,…,T N Representing capacity requirement of each of at least one traffic flow, RRC 1 ,RRC 2 ,…,RRC N Representing the number of RRC connections per service flow in at least one service flow, RSC 1 ,RSC 2 ,…,RSC N The number of RRC connections with data transmission for each of the at least one traffic flow is indicated, the total number of traffic flows being N.
And then, the carrier resource scheduling device calculates the priority parameter of the second service flow according to the key parameter, the 5QI, the arrival time and the demand time of the second service flow. Wherein the second service flow is any service flow in the service flows. Specifically, the priority parameter of the second service flow satisfies the formula

Representing the priority parameter, K, of the second traffic flow i Key parameter, time, representing the second traffic flow i Representing the arrival time of the second traffic flow, Last i Representing the length of time of demand of the second traffic flow PrL i 5QI, TTI representing second traffic flow pre The TTI represents the duration of one scheduling period, last, representing the difference between the arrival time of the second traffic stream and the time from the previous scheduling instant 1 ,Last 2 ,…,Last N The required time length of each service flow in at least one service flow is represented, and the total number of the service flows is N.
304. And the carrier resource scheduling device performs carrier resource scheduling on at least one service flow according to the priority parameter and the network type of each service flow.
Before carrying out carrier resource scheduling on at least one service flow, the carrier resource scheduling device needs to judge whether the shared carrier base station can access the service flow.
Specifically, when determining that at least one of the following parameters is greater than or equal to a corresponding preset threshold, the carrier resource scheduling device determines that the shared carrier base station cannot access the service flow, and refuses to access the at least one service flow.
The parameters include the total capacity of the accessed service, the number of connected RRC connection, the CPU occupation amount of the central processing unit and the key value.
