In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.
With the continuous evolution of networks, the network requirements of industry users have become an important deployment requirement of the fifth generation mobile communication technology (5-generation, 5G). However, the 5G base station generally adopts a device structure with multiple elements such as 192 elements, 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 that of the base station in the frequency band below 2GHz, which also leads to the multiplication of the number of stations in unit area. Thus, the high base station cost and the dense number of base stations will result in an exponential increase in the cost of the operator.
The shared base station is built together, so that the base station cost required to be invested by an operator is reduced, and the requirement of multiple operators for deploying public network services is met. At present, a base station of a single operator generally carries public network services and private network services, or a plurality of operators commonly share a shared base station to carry public network services. It can be seen that the co-established shared base station cannot synchronously support the public network service and the private network service of different operators. And furthermore, the scheduling of carrier resources of independent carriers in public network services and private network services of different operators cannot be supported.
In order to solve the above problem, 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 utilizing a baseband processing unit, then, uplink data and downlink data are respectively combined together by utilizing a radio frequency unit and output to the same antenna unit. The baseband processing unit of the independent carrier base station adopts a plurality of optical fibers to connect different 5G core networks (such as a public network core network and a private network core network of an operator) for interaction between the independent carrier base station and the core networks. Therefore, in the independent carrier base station, the service processing can be realized in a manner that one carrier corresponds to two carriers, one carrier corresponds to the public network service of the carrier, and the other carrier corresponds to the private network service of the carrier.
The carrier resource scheduling method in the embodiment of the application is applied to the scene of the independent carrier base station for scheduling the carrier resources of the service. A carrier resource scheduling device acquires network information of each service flow in at least one service flow and a dependent parameter 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 the operator of each target service flow and a preset rule; executing a first operation on each classified service flow to obtain a scheduling sequence of each target service flow in each service flow; and carrying out carrier resource scheduling on the carrier corresponding to each type of service flow according to the scheduling sequence of each target service flow. The requirement that multiple operators deploy public network services and private network services in the independent carrier base station at the same time can be met, and the application range of the independent carrier base station is widened.

After introducing the application scenario and the implementation environment of the embodiment of the present application, a carrier resource scheduling method provided in the embodiment of the present application is described below with reference to fig. 3 in conjunction with the carrier resource scheduling apparatus shown in fig. 2.
Fig. 3 is a flowchart illustrating 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 the network information of each service flow in at least one service flow and the dependent parameters of the target area.
Wherein the dependent parameters comprise a capacity dependent parameter and a user number dependent parameter.
Specifically, the method for the carrier resource scheduling device to obtain the dependent parameter of the target region includes the following step 301 a.
301a, the carrier resource scheduling device first obtains a first number and a second number of the target area in a preset time period.
Wherein the preset time period comprises at least one hour; the first number is the number of hours in which the transmission data amount is larger than a first threshold value in at least one hour; the second number is a number of hours for which the number of RRC connections is greater than a second threshold for at least one hour. The preset time period is preset, and may be a default value, or a numerical value written by a relevant person according to an actual situation, for example. For another example, the preset time period is a working day of 1 day and a non-working day of one day in two consecutive weeks.
Specifically, the carrier resource scheduling device collects information such as a network type of an access independent carrier base station service and a Radio Resource Control (RRC) connection number of the 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 maximum capacity of the service, the average RRC connection number of the service, the maximum RRC connection number of the service, the average number of the RRC connections with data transmission, and the maximum number of the RRC connections with data transmission, which correspond to each hour in two consecutive weeks, i.e., a working day of 1 day and a non-working day of 1 day, during a 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 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 the first threshold value within the first hour, the carrier resource scheduling device determines that the first hour is the number of hours that the big data service dominates, and adds one to the first number. And calculating all the acquisition hours by adopting the counting method of the first quantity, and accumulating to obtain the numerical value of the first quantity. Wherein the first hour is any one of the collection hours; the first 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 first threshold is determined by the relevant person according to a ratio of a sum of a data amount of a public network service and a data amount of a private network service, which are accessed in the independent carrier base station, to a total service capacity that the independent carrier base station can access within a first hour.
If the sum of the average RRC connection number of the public network service and the average RRC connection number of the private network service accessed in the independent carrier base station is larger than a second threshold value within a second hour, or the sum of the average number of the RRC connection number transmitted by the public network service and the average number of the RRC connection number transmitted by the private network service accessed in the independent carrier base station is larger than the second threshold value, the carrier resource scheduling device determines that the second hour is the number of hours in which the number of users is dominant, and the second number is added by one. And calculating all the acquisition hours by adopting the counting method of the second quantity, and accumulating to obtain the numerical value of the second quantity. 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 the relevant person according to an actual situation, for example, the relevant person determines the second threshold according to a ratio of the average RRC connection number of the public network service accessed in the independent carrier base station to the average RRC connection number of the private network service to the total RRC connection number connectable by the independent carrier base station in the first hour, or the relevant person determines the second threshold according to a ratio of the average number of RRC connection of the public network service accessed in the independent carrier base station to the average number of connection of the private network service to the total number of connection of the independent carrier base station in the first hour.
Then, the carrier resource scheduling means calculates a dependent parameter of the capacity target region and a user number dependent parameter based on the first number and the second number.
Specifically, the capacity-dependent parameter satisfies the formula
User number dependent parameter satisfaction
Wherein the content of the first and second substances,
the first number is represented by a first number,
denotes a second number, ZTRepresenting a capacity-dependent parameter, ZRIndicating a user number dependent parameter.
Then, the carrier resource scheduling device determines whether load balancing is required when the 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 hour duration of the target area satisfies the formula H ═ Σd∑i HiWherein d represents the number of days of collection, HiRepresents the ith collection hour. And then, the carrier resource scheduling device judges whether load balancing is needed or not when the carrier resource scheduling is carried out according to the total busy hour duration, 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 busy hour duration is smaller than a third threshold, or the ratio of the second number to the total busy hour duration is smaller than a fourth threshold, it is determined that load balancing is required when the carrier resources are scheduled. The third threshold may be a default value or a numerical value written by a related person according to an actual situation. For example, the third threshold is 0.3. The fourth threshold may be a default value or a numerical value written by a relevant person according to an actual situation. For example, the fourth threshold is 0.3.
And 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 frequency point information of the service flow, a network identifier of the service flow, a Data Network Name (DNN) of the service flow, a quality of service identifier (5G QoS identifier, 5QI) of the service flow, a capacity requirement of the service flow, a number of RRC connections of the service flow, an arrival time of the service flow, and a required 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 301 b.
301b, the carrier resource scheduling device determines that the service terminal has a service access requirement, and then obtains information such as a Master Information Block (MIB), a System Information Block (SIB), a Protocol Data Unit (PDU) session establishment request (PDU session initiation request), a Session Management Function (SMF) -unified data management function (UDM) registration (SMF-UDM registration), and the like 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 the PDU session estimation request, and extracts the QI 5 of the service flow, the capacity requirement of the service flow, the number of RRC connections with data transmission of the service flow, the arrival time of the service flow, and the required duration of the service flow from the SMF-UDM registration.
The 5QI of the service flow is a scalar used for indexing the 5G QoS characteristics, and the 5QI parameter in the present application is a priority level corresponding to the service flow in the 5G QoS characteristics. There is a standardized 5QI mapping relation in the ts23.501table 5.7.4-1 protocol, in the 5G QoS characteristics, the priority level indicates the resource scheduling priority among 5G QoS streams, this parameter is used to distinguish the QoS streams of one service terminal and also to distinguish the QoS streams of different terminals, and the smaller the value of the priority level, the higher the priority is.
302. And the carrier resource scheduling device determines an operator 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 identifier 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 stream with the frequency point information and the bandwidth information of the operator, which are stored in advance, to obtain the operator corresponding to each service stream. The network identifier is used to indicate whether the home network of the traffic flow is a public network or a private network.
303. And the carrier resource scheduling device determines at least one target service flow in the 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 dependence parameter 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 according to 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 service flow whose home network is the public network is the target service flow, all the service flows whose home network is the public network in the at least one service flow are determined as the target service flow (i.e., the target service flow does not include the service flow whose home network is the private network). Similarly, if the carrier resource scheduling device determines that the service flow of which the home network is the private network is the target service flow, all the service flows of which the home network is the private network in the at least one service flow are determined as the target service flow (that is, the target service flow does not include the service flow of which the home network is the public network).
Optionally, in a 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 to obtain the network type of the at least one target service flow. Wherein the first judgment is as follows: and 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, determining that the network type of the first service flow is the first private network of the first operator. The first service flow is any one of at least one target service flow.
Of course, under the condition that the home network of the target service flow is unknown, the network type of each target service flow can 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 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, so as to obtain the network type of each target service flow. Wherein the second judgment is that: if the frequency point information of the third service flow is determined to correspond to the second operator and the network identifier of the third service flow is the public network, determining that the network type of the third service flow is the public network of the second operator; and if the frequency point information of the third service flow is determined to correspond to a third operator, the network identifier of the third service flow is a private network, and the DNN of the third service flow corresponds to a second private network, determining that the network type of the third service flow is the second private network of the third operator. The third service flow is any one of at least one target service flow.
And then, the carrier resource scheduling device determines the priority parameter of each target service flow according to the dependent parameter and the network information.
Specifically, the carrier resource scheduling device performs 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 a key parameter of the second service flow according to a capacity requirement of the second service flow, the number of RRC connections with data transmission of the second service flow, a capacity dependent parameter, and a user number dependent parameter. The second service flow is any one of at least one target service flow.
Specifically, the key parameter of the second service flow satisfies the formula:
wherein Z isTiA capacity dependent parameter, Z, representing the target areaRiUser number dependent parameter, K, representing a target areaiRepresenting a key parameter, T, of the second traffic flowiIndicating the capacity requirement, RRC, of the second traffic flowiIndicates the number of RRC connections, RSC, of the second traffic flowiNumber of RRC connections with data transfer, T, representing second traffic flow1,T2,…,TNIndicating the capacity requirement, RRC, of each of the target traffic flows comprised by the network type to which the second traffic flow belongs1,RRC2,…,RRCNIndicating each target service flow included in the network type of the second service flowRRC connection number, RSC1,RSC2,…,RSCNThe number of the RRC connections with data transmission of each target service flow in the target service flows included in the network type to which the second service flow belongs is represented, and the number of the target service flows included in the network type to which the second service flow belongs is N.
Then, the carrier resource scheduling device calculates the priority parameter of the second service flow according to the key parameter, 5QI, arrival time and required duration of the second service flow. The second service flow is any one of the service flows.
Specifically, the priority parameter of the second service flow satisfies the formula
Wherein the content of the first and second substances,

304. And 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.
Wherein, the preset rule is as follows: the target traffic flows of the same operator are of one type.
Optionally, the carrier resource scheduling device may further perform secondary classification on at least one service flow according to the network type and the preset rule of each service flow. Wherein, the service 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 a scheduling sequence of each target service flow in each service flow.
Specifically, the first operation is: and the carrier resource scheduling device sequences the target service flows in the first class of service flows according to the priority parameters in the first class of service flows to obtain the scheduling sequence of each target service flow in the first class of service flows. The first type of service flow is a target service flow corresponding to any operator.
For example, in a case that the home network of the target service flow is a public network, taking an example that at least one target service flow is divided into two types (an operator a public network and an operator B public network), the carrier resource scheduling device sorts the target service flows in each type of service flow according to the size of the priority parameter, and the sequence of the sorted target service flows is as shown in table 2 below.

Illustratively, in a case that a home network of a target service flow is a private network, the carrier resource scheduling device sorts the target service flows in the first class of service flows according to the size of the priority parameter, and the sequence of the sorted target service flows is as shown in table 3 below.

306. And the carrier resource scheduling device performs carrier resource scheduling 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.
Before scheduling carrier resources for at least one service flow, the carrier resource scheduling device needs to first determine whether a target carrier or an independent carrier base station can also access the service flow. The target carrier is a carrier corresponding to any one type of service flow in each type of service flow.
Specifically, when determining 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 then the carrier resource scheduling device denies access to the at least one service flow.
The parameters comprise 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 key values. The key value is the sum of key parameters of any type of service flow in the at least one target service flow. The preset threshold corresponding to the parameter may be a default value, or may be a numerical value set by a relevant 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 traffic is determined as the threshold corresponding to the total capacity of the traffic that has accessed the target carrier; ninety percent of the total number of RRC connections which can be connected by the target carrier is determined as a threshold corresponding to the number of RRC connections of the connected target carrier; and determining ninety percent of the total CPU capacity of the independent carrier base station as a threshold corresponding to the CPU occupation amount.
And when determining that 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 all smaller than the corresponding preset threshold values, the carrier resource scheduling device accesses the service flows 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 apparatus performs carrier resource scheduling according to the classification result in step 304 and the scheduling order 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 order of each target service flow in each type of service flow.
Further, the carrier resource scheduling device determines the network type of each target service flow. And scheduling carrier resources on the carrier corresponding to each type of service flow according to the network type and 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 parameter of the target cell. Then, a plurality of service flows are classified according to operators, and carrier resource scheduling is carried out on the classified service flows according to the priority parameters. The method for scheduling the carrier resources of the independent carrier in the public network service and the private network service of different operators is provided, the requirement that multiple operators deploy the public network service and the private network service in the independent carrier base station at the same time is met, and the application range of the independent carrier base station is widened.
