Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. 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 cannot be supported further.
In order to solve the above problems, the present application provides an independent carrier base station that synchronously supports public network services and private network services of different operators. The independent carrier base station adopts a multi-carrier mode, firstly, public network services and private network services of different operators are respectively modulated on different carriers 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 independent 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 independent carrier base station and the core network. Therefore, in the independent carrier base station, the service processing can be realized in a mode that one carrier corresponds to two carriers and one carrier corresponds to the public network service of the carrier and one carrier corresponds to the private network service of the carrier.
The carrier resource scheduling method of the embodiment is applied to the scenario of carrier resource scheduling of the service performed by the independent 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; determining an operator and a home network of each service flow according to the network information; determining at least one target service flow according to the home network; determining a priority parameter of each target service flow according to the dependent parameters and the network information; classifying the target service flows according to operators and preset rules of each target service flow; executing a first operation on each classified service flow to obtain a scheduling sequence of each target service flow in each classified service flow; and carrying out carrier resource scheduling on the carriers corresponding to each type of service flow according to the scheduling sequence of each target service flow. The method can meet the requirement that a plurality of operators can simultaneously deploy public network service and private network service in the independent carrier base station, and widens the application range of the independent carrier base station.

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 an independent carrier base station, and the independent 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 of the service of the access independent carrier base station and radio resource control protocol (radio resource control, RRC) connection number of the service in 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, which correspond to each hour, in a busy time period, in two consecutive weeks, 1 day working day and 1 day non-working day.
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 independent 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 independent carrier base station is greater than a first threshold value 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 independent carrier base station in a first hour, and the ratio of the data volume to the total service capacity that can be accessed by the independent carrier base station.
If the sum of the average RRC connection number of the public network service accessed in the independent 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 independent 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 independent 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 independent 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 independent carrier base station to the average RRC connection number of private network services in the first hour, and the ratio of the average RRC connection number of the total RRC connection number of public network services to the total RRC connection number of private network services.
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 parameter satisfaction
Wherein (1)>
Representing a first quantity, +.>
Representing a second number, Z T Representing capacity dependent parameters, Z R Indicating the user number dependent parameters.
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 independent 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. Then, the carrier resource scheduling device is used for scheduling the carrier resources according to the targetAnd judging whether load balancing is needed when carrier resource scheduling is carried out or not according to the total busy time duration, the first quantity and the second quantity of the areas. 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 comprises frequency point information of the service flow, network identification 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 master information block (master information block, MIB), a system information block (system information block, SIB), 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 frequency point information of the service flow from the MIB, extracts the network identifier of the service flow from the SIB, extracts the DNN of the service flow from PDU session establishment request, and extracts the 5QI of the service flow, the capacity requirement of the service flow, the RRC connection number with data transmission of the service flow, the arrival time of the service flow and the required time 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 standardized 5QI mapping relationship in the ts23.501table 5.7.4-1 protocol, in the 5G QoS characteristics, the priority level represents the resource scheduling priority among the 5G QoS flows, the parameter is used for distinguishing the QoS flows of one service terminal and also used for distinguishing the 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 determines the operators of each service flow according to the frequency point information of each service flow, and determines the home network of each service flow according to the network identification of each service flow.
Specifically, since the frequency point information and the bandwidth information used by each operator are fixed, the carrier resource scheduling device compares the frequency point information of the service flow with the frequency point information and the bandwidth information of the pre-stored operators to obtain the operators corresponding to each service flow. The network identity is used to indicate whether the home network of the traffic flow is a public network or a private network.
303. The carrier resource scheduling device determines at least one target service flow in at least one service flow according to the home network of each service flow, and determines the priority parameter of each target service flow according to the dependent parameters and the network information.
Wherein the home network of the target service flow is a public network or a private network.
It should be noted that when determining the target traffic flow based on the home network of each traffic flow, the home network should be selected based on the same type. For example, if the carrier resource scheduling device determines that the traffic flow whose home network is the public network is the target traffic flow, all traffic flows whose home network is the public network in at least one traffic flow are determined to be the target traffic flow (i.e., the target traffic flow does not include the traffic flow whose home network is the private network). Similarly, if the carrier resource scheduling device determines that the service flow with the home network being the private network is the target service flow, all the service flows with the home network being the private network in at least one service flow are determined to be the target service flows (i.e. the target service flows do not include the service flows with the home network being the public network).
Optionally, in the case that the home network of the target service flow is a private network, the carrier resource scheduling device determines the network type of each service flow according to the DNN of each target service flow.
Specifically, the carrier resource scheduling device performs a first judgment on at least one target service flow according to the DNN of each target service flow, so as to obtain the network type of at least one target service flow. Wherein, the first judgement is: if the frequency point information of the first service flow is determined to correspond to the first operator, the network identifier of the first service flow is a private network, and the DNN of the first service flow corresponds to the first private network, the network type of the first service flow is determined to be the first private network of the first operator. The first traffic flow is any one of the at least one target traffic flow.
Of course, in the case that the home network of the target service flow is unknown, the network type of each target service flow may be directly determined according to the frequency point information, the network identifier and the DNN of each target service flow.
Specifically, the carrier resource scheduling device performs a second judgment on at least one target service flow according to the frequency point information, the network identifier and the DNN of each target service flow to obtain the network type of each target service flow. Wherein, the second judgment is: if the frequency point information of the third service flow corresponds to the second operator and the network identifier of the third service flow is a public network, determining that the network type of the third service flow is the public network of the second operator; if the frequency point information of the third service flow corresponds to the third operator, the network identifier of the third service flow is a private network, and the DNN of the third service flow corresponds to the second private network, the network type of the third service flow is determined to be the second private network of the third operator. Wherein the third traffic flow is any one of the at least one target traffic flow.
And then, the carrier resource scheduling device determines the priority parameter of each target service flow according to the dependent parameters and the network information.
Specifically, the carrier resource scheduling device executes a second operation on each target service flow to obtain a priority parameter of each target service flow.
Wherein the second operation is: first, the carrier resource scheduling device calculates key parameters of the second service flow according to capacity requirements of the second service flow, the number of RRC connections with data transmission of the second service flow, capacity dependent parameters and user number dependent parameters. Wherein the second traffic flow is any one of the at least one target traffic flow.
Specifically, the key parameters of the second service 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 the capacity requirement of each of the target traffic flows included in the network type to which the second traffic flow belongs, RRC 1 ,RRC 2 ,…,RRC N Representing the RRC connection number of each of the target traffic flows included in the network type to which the second traffic flow belongs, RSC 1 ,RSC 2 ,…,RSC N The number of RRC connections with data transmission for each of the target traffic flows included in the network type to which the second traffic flow belongs is indicated, and the number of target traffic flows included in the network type to which the second traffic flow belongs is 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

304. The carrier resource scheduling device classifies at least one target service flow according to the operator of each target service flow and a preset rule.
The preset rules are as follows: the target traffic flows of the same operator are of one class.
Optionally, the carrier resource scheduling device may further perform secondary classification on at least one service flow according to a network type and a preset rule of each service flow. Wherein the traffic flows of the same network type are of one type.
305. And the carrier resource scheduling device executes a first operation on each classified service flow to obtain the scheduling sequence of each target service flow in each classified service flow.
Specifically, the first operation is: and the carrier resource scheduling device orders the target service flows in the first type of service flows according to the size of the priority parameter in the first type of service flows to obtain the scheduling sequence of each target service flow in the first type of service flows. The first type of service flow is a target service flow corresponding to any operator.
In an exemplary case where the home network of the target traffic flows is a public network, taking at least one of the target traffic flows as an example, the target traffic flows are divided into two classes (a operator public network and B operator public network), the carrier resource scheduling device sorts the target traffic flows in each class according to the size of the priority parameter, and the sorted target traffic flows are in the following table 2.
TABLE 2
For example, in the case that the home network of the target traffic is a private network, the carrier resource scheduling device sorts the target traffic in the first class traffic according to the size of the priority parameter, and the sorted target traffic is in the following order as shown in table 3.

306. And the carrier resource scheduling device performs carrier resource scheduling according to the scheduling sequence of each target service flow in each type of service flow on the carrier corresponding to each type of service flow.
Before carrying out carrier resource scheduling on at least one service flow, the carrier resource scheduling device needs to judge whether the target carrier or the independent carrier base station can access the service flow. The target carrier is a carrier corresponding to any one of the service flows in each type of service flows.
Specifically, when the carrier resource scheduling device determines that at least one of the following parameters is greater than or equal to the corresponding preset threshold, the carrier resource scheduling device determines that the target carrier or the independent carrier base station cannot access the service flow, and the carrier resource scheduling device refuses to access the at least one service flow.
The parameters include the total capacity of the service of the accessed target carrier, the RRC connection number of the connected target carrier, the CPU occupation amount and the key value. The key value is the sum of key parameters of any type of traffic flow in the at least one target traffic flow. The preset threshold corresponding to the parameter may be a default value, or may be a value set by a related person according to the parameter of the independent carrier base station. For example, ninety percent of the total capacity of the target carrier that can access the service is determined as a threshold corresponding to the total capacity of the service that has accessed the target carrier; ninety percent of the total RRC connection number of the target carrier can be connected is determined as a threshold value corresponding to the RRC connection number of the connected target carrier; ninety percent of the total capacity of the CPU of the independent carrier base station is determined as a threshold corresponding to the CPU occupation amount.
And the carrier resource scheduling device accesses the service flows when the total capacity of the service accessed to the target carrier, the RRC connection number of the connected target carrier, the CPU occupation amount and the key value are smaller than the corresponding preset threshold value, and performs carrier resource scheduling according to the scheduling sequence of each service flow in each type of service flow on the carrier corresponding to each type of service flow.
Specifically, in the independent carrier base station, one operator corresponds to two carriers, so the carrier resource scheduling device performs carrier resource scheduling according to the classification result in step 304 and the scheduling sequence of each service flow in each type of service flow determined in step 305, and on the carrier corresponding to each type of service flow, according to the scheduling sequence of each target service flow in each type of service flow.
Further, if the carrier resource scheduling device determines the network type of each target service flow. And carrier resource scheduling can be performed on carriers corresponding to each type of service flow according to the network type and the scheduling sequence of each target service flow in each type of service flow.
In the above scheme, the operator and the priority parameter of each service flow are determined according to the network information of the service flow and the dependent parameters of the target cell.
