Referring to fig. 1, an embodiment of the present application provides a network architecture, including:

UE, base station and core network. The communication network where the UE, the base station and the core network are located may be an LTE network.

The corresponding relation between the service type and the QCI and the corresponding relation between the identity type of the UE and the QCI are stored in the core network. The service types may include voice over long-term evolution (VoLTE) voice, voLTE video, game, internet protocol address multimedia subsystem (internet protocol address multimedia subsystem, IMS) signaling, payment, downloading, etc., and the core network may store the corresponding relationship between the service types and QCI as shown in table 1, see table 1 below.

		VIP user	8
……	……

The base station stores the corresponding relation between the numerical range of the load parameter and the load level, and the corresponding relation between the QCI, the load level and the numerical value of the wireless dispatching parameter. The load level is used for reflecting the load of the cell, and the larger the load of the cell is, the higher the load level of the cell is, the smaller the load of the cell is, and the lower the load level of the cell is. For example, referring to the correspondence between the numerical ranges of the load parameters and the load levels shown in table 3 below, it is assumed that the base station classifies the load levels of the cell into three levels of light load, medium load and heavy load, and defines the numerical range of the load parameter corresponding to each load level.

TABLE 3 Table 3

The values of the wireless scheduling parameters may include at least one of a wireless scheduling weight, a minimum guaranteed rate, and the like, so the corresponding relation of the QCI, the load level, and the values of the wireless scheduling parameters includes a corresponding relation of the QCI, the load level, and the wireless scheduling weight, and/or a corresponding relation of the QCI, the load level, and the minimum guaranteed rate. For example, the base station may store the corresponding relationship between the QCI and the load level and the radio scheduling weight as shown in table 4 below, and may store the corresponding relationship between the QCI and the load level and the minimum guaranteed speed as shown in table 5 below.

TABLE 4 Table 4

QCI	Load level	Wireless scheduling weights
			1	Light load	100
1	Medium load	300
			1	Heavy duty	600
2	Light load	100
			2	Medium load	400
2	Heavy duty	900
			……	……	……

TABLE 5

QCI	Load level	Minimum guaranteed rate
			1	Light load	100kb/s
1	Medium load	300kb/s
			1	Heavy duty	500kb/s
2	Light load	100kb/s
			2	Medium load	330kb/s
2	Heavy duty	600kb/s
			……	……	……

Referring to the above tables 4 and 5, the lower the load level of the cell, the smaller the difference between the values of the radio scheduling parameters corresponding to different QCIs. The higher the load level of the cell, the larger the difference between the values of the radio scheduling parameters corresponding to different QCIs.

Referring to fig. 2, the wireless scheduling system may further include a management end, where the management end may send the corresponding relation between the numerical range of the load parameter and the load level and send the corresponding relation between the QCI, the load level and the numerical value of the wireless scheduling parameter to the base station. The base station receives and stores the corresponding relation between the numerical range of the load parameter and the load level, and receives and stores the corresponding relation between the QCI, the load level and the numerical value of the wireless dispatching parameter.

The technician can set the corresponding relation between the numerical range of the load parameter and the load level and the corresponding relation between the QCI, the load level and the numerical value of the wireless dispatching parameter at the management end. And then, the management end sends the corresponding relation between the numerical range of the load parameter and the load level and the corresponding relation between the QCI, the load level and the numerical value of the wireless scheduling parameter to the base station.

Optionally, a technician may set a configuration file on the management end, where the configuration file stores a corresponding relationship between a numerical range of the load parameter and the load level and a corresponding relationship between the QCI, the load level and a numerical value of the wireless scheduling parameter. The management end sends the configuration file to the base station, and the base station correspondingly receives and stores the configuration file.

The connection between the UE and the core network includes a connection between the UE and the base station and a connection between the base station and the core network, and messages interacted between the UE and the core network are forwarded through the base station when the connection between the UE and the core network is established. In the process of establishing connection between the UE and the core network, the UE sends an establishment request message carrying the identification of the UE to the core network, the core network receives the establishment request message, acquires the identity type of the UE according to the identification of the UE carried by the establishment request message, acquires the QCI corresponding to the identity type of the UE from the corresponding relation between the identity type and the QCI according to the identity type of the UE, sends the QCI corresponding to the identity type of the UE to the base station, and the base station receives the QCI corresponding to the identity type of the UE. Or alternatively, the process may be performed,

before the UE transmits the service with the core network, the UE transmits a request message carrying the service type of the service to the core network, the core network receives the request message, acquires the QCI corresponding to the service transmitted by the UE from the corresponding relation between the service type and the QCI according to the service type carried by the request message, and transmits the QCI corresponding to the service transmitted by the UE to the base station, and the base station receives the QCI corresponding to the service transmitted by the UE.

After receiving the QCI corresponding to the identity type of the UE or the QCI corresponding to the service currently transmitted by the UE, the base station may acquire the value of the load parameter of the cell in which the UE is located, and determine the load level of the cell in which the UE is located according to the value of the load parameter and the corresponding relationship between the value range of the load parameter and the load level. And acquiring the value of the wireless scheduling parameter from the corresponding relation of the QCI, the load level and the value of the wireless scheduling parameter according to the received QCI and the load level, and acquiring the scheduling priority of the UE according to the value of the wireless scheduling parameter. And scheduling the UE according to the scheduling priority.

The base station may first obtain the scheduling priority of the UE after receiving the QCI, and schedule the UE according to the scheduling priority when the UE needs to be scheduled. Or when the base station needs to schedule the UE, the base station acquires the scheduling priority according to the mode and schedules the UE according to the scheduling priority.

Optionally, when the base station transmits data to the UE, the base station needs to schedule the UE, and after the UE is scheduled, the base station starts to transmit data to the UE. Or when the UE transmits data to the base station, the UE transmits a scheduling request to the base station, the base station receives the scheduling request, determines that the UE needs to be scheduled, and transmits the data to the base station after the UE is scheduled.

Optionally, the load parameter is used to describe the load size of the cell. The value of the load parameter may be the load size of the cell.

Referring to fig. 3, an embodiment of the present application provides a method for scheduling devices, where the method may be applied to a network architecture as shown in fig. 1 or 2, and the method includes:

step 201: the base station acquires a QCI corresponding to the identity type of the UE or corresponding to the service currently transmitted by the UE.

In this step, the base station receives the QCI corresponding to the identity type of the UE transmitted by the core network, or receives the QCI corresponding to the service currently transmitted by the UE transmitted by the core network.

The UE establishes a connection between the UE and the core network before transmitting data to the core network or before receiving data transmitted by the core network, the connection between the UE and the core network including a connection between the UE and a base station and a connection between the base station and the core network. When the UE establishes connection with the core network, the UE sends an establishment request message carrying the identification of the UE to the core network, the core network receives the establishment request message, acquires the identity type of the UE according to the identification of the UE carried by the establishment request message, acquires the corresponding QCI from the corresponding relation between the identity type and the QCI according to the identity type of the UE, takes the acquired QCI as the QCI corresponding to the identity type of the UE, sends the QCI corresponding to the identity type of the UE to the base station, and the base station receives the QCI corresponding to the identity type of the UE. Or alternatively, the process may be performed,

before the UE transmits the service with the core network, the UE transmits a request message carrying the service type of the service to the core network, the core network receives the request message, acquires a corresponding QCI from the corresponding relation between the service type and the QCI according to the service type carried by the request message, takes the acquired QCI as the QCI corresponding to the service transmitted by the UE, and transmits the QCI corresponding to the service transmitted by the UE to the base station, and the base station receives the QCI corresponding to the service transmitted by the UE.

Before executing this step, when the UE registers in the core network, the UE sends the identity of the UE and the identity type of the UE to the core network. The core network receives the identification of the UE and the identity type of the UE, and stores the corresponding relation between the identification of the UE and the identity type of the UE in the corresponding relation between the identification of the UE and the identity type of the UE. Thus, when the core network acquires the identity type of the UE, the identity type of the UE is acquired from the corresponding relation between the identity of the UE and the identity type of the UE according to the identity of the UE.

Step 202: and the base station acquires the value of the load parameter of the cell where the UE is located.

The load parameter includes at least one of a number of users accessing the cell and a physical resource block (physical resource block, PRB) utilization of the cell.

PRBs correspond to 12 consecutive carriers (180K in the case of 15K carrier spacing) in the frequency domain and resources of one slot (half a subframe, 0.5 ms) in the time domain.

The base station may periodically acquire the value of the load parameter of the cell.

For example, the base station obtains the value of the load parameter of the cell where the UE is located as S, and it is assumed that S is greater than the first threshold and less than the second threshold.

Step 203: and the base station determines the load level of the cell according to the value of the load parameter and the corresponding relation between the value range of the load parameter and the load level.

The base station stores the corresponding relation between the numerical range of the load parameter and the load level. The base station acquires the corresponding relation between the stored numerical ranges of the load parameters and the load levels, determines the numerical range of the load parameter where the numerical value of the load parameter is located from the numerical ranges of the load parameters stored in the corresponding relation between the numerical range of the load parameter and the load levels, acquires the corresponding load level from the corresponding relation between the numerical range of the load parameter and the load level according to the numerical range of the load parameter where the numerical value of the load parameter is located, and takes the acquired load level as the load level of the cell.

For example, the correspondence relationship between the load ranges and the load levels of the load parameters shown in table 3 includes three numerical ranges of the load parameters, which are a first numerical range smaller than or equal to a first threshold, a second numerical range larger than the first threshold and smaller than a second threshold, and a third numerical range larger than or equal to the second threshold, respectively. The base station determines a second numerical range in which the numerical value S of the load parameter is located from the first numerical range, the second numerical range and the third numerical range, acquires a corresponding load level as a medium load from the corresponding relation between the numerical range of the load parameter and the load level shown in table 3 according to the second numerical range, and takes the acquired load level as the load level of the cell.

When the load parameter includes the number of users accessed by the cell and the PRB utilization rate, the number of users and the PRB utilization rate can be weighted and calculated to obtain a comprehensive parameter value. And taking the comprehensive parameter value as the value of the load parameter, determining the value range of the load parameter where the comprehensive parameter value is located from the value ranges of the load parameters stored in the correspondence between the load parameter ranges and the load levels, and acquiring the corresponding load level from the correspondence between the value ranges of the load parameters and the load level according to the determined value range of the load parameter as the load level of the cell.

Since the base station can periodically acquire the value of the load parameter of the cell, the base station acquires the load level of the cell through this step every time the value of the load parameter of the cell is acquired, that is, the base station also periodically acquires the load level of the cell.

The load level of the cell may change continuously. In order to avoid that the scheduling priority for scheduling the UE is re-acquired as soon as the load level of the cell changes, m first load levels may be continuously acquired, where m first load levels are load levels periodically acquired by the base station during a period of time with a duration being a preset duration, and m is an integer greater than 1. If the m first load levels acquired are all the same and the first load level is different from the second load level, step 204 may be performed where the second load level is the load level acquired before the m first load levels are acquired, i.e., the second load level is the load level acquired last between the time periods.

Referring to fig. 4, a base station periodically acquires a value of a load parameter of the cell in a first time t1 to a second time t2, wherein the first time t1 is located before the second time t2, a duration between the first time t1 and the second time t2 is a preset duration, and the load level of the cell is determined according to the value of the load parameter acquired each time and a corresponding relation between a value range of the load parameter and the load level. For ease of explanation, the m load levels acquired in the first time t1 to the second time t2 are referred to as a first load level, and m is an integer greater than 1. Referring to fig. 4, m first load levels acquired in the first time t1 to the second time t2 are all "medium load", the first load level "medium load" is higher than the second load level "light load", and the second load level "light load" is the load level determined last before the first time t1, and the following operation starts to be performed in step 204.

Step 204: and the base station acquires the numerical value of the wireless scheduling parameter from the corresponding relation among the load level, the QCI and the numerical value of the wireless scheduling parameter according to the first load level and the QCI.

The base station stores the corresponding relation of the load level, QCI and the numerical value of the wireless dispatching parameter, in the step, the base station obtains the corresponding relation of the stored load level, QCI and the numerical value of the wireless dispatching parameter, when m first load levels determined in the first time t1 to the second time t2 are equal and the first load level is different from the second load level, and the numerical value of the wireless dispatching parameter is obtained from the corresponding relation of the load level, QCI and the numerical value of the wireless dispatching parameter according to the first load level and the QCI in the second time t 2.

The wireless scheduling parameters may include at least one of a wireless scheduling weight, a minimum guaranteed rate, and the like. In this step, the wireless scheduling weight may be obtained from the corresponding relationship between the load level, the QCI, and the wireless scheduling weight according to the first load level and the QCI, and/or the minimum guaranteed rate may be obtained from the corresponding relationship between the load level, the QCI, and the minimum guaranteed rate according to the first load level and the QCI.

For example, assuming that the acquired QCI is 1, referring to fig. 4, the first load levels acquired by the base station in the first time t1 to the second time t2 are all "medium load" and are different from the second load level "light load" acquired before the first time t1, so in this step, the radio scheduling weight is acquired as 300 from the corresponding relation of the load level, QCI and radio scheduling weight as shown in table 4 according to the first load level "medium load" and the QCI "1", and the minimum guarantee rate is acquired as 100kb/s from the corresponding relation of the load level, QCI and the minimum guarantee rate as shown in table 5 according to the first load level "medium load" and the QCI "1".

Step 205: and the base station acquires the scheduling priority of the UE according to the numerical value of the wireless scheduling parameter, wherein the scheduling priority is used for describing the scheduling sequence of the UE by the base station.

In this step, the base station may acquire the scheduling priority of the UE through the following first formula.

The first formula is:

in the first formula, priority is the scheduling Priority of the UE, and eff is the channel quality of the UE.

Alpha is the capacity factor initially configured by the base station.

When the capacity factor is equal to 1, the selection of Non-guaranteed bit rate (guaranteed bit rate, non-GBR) traffic priority follows the scheduling resource fairness principle.

When the capacity factor is less than 1, it means that the selection of Non-GBR traffic priority tends to rate fairness principles.

When the capacity factor is greater than 1, the principle that the selection of Non-GBR service priority tends to be capacity priority is indicated.

r is the rate of UE historical transmissions.

Y _QCI Scheduling for the wirelessThe value of the parameter may be the wireless scheduling weight, or may be the minimum guaranteed rate, or may be the result of performing weighted calculation on the wireless scheduling weight and the minimum guaranteed rate.

Coeff _SPID The downlink scheduling priority weighting coefficient of the service profile identifier (service profile identifier, SPID) user pre-configured for the base station is valid only when the base station normally recognizes that the UE is a SPID user.

f (delay) is the time delay of waiting for scheduling by the UE at the base station side, and the time delay can be obtained by timing by the base station.

After the base station acquires the scheduling priority of the UE, the scheduling priority of the UE may be saved.

After the step is performed, that is, after the second time, the load level of the cell is still periodically acquired, and it is assumed that the load level of the cell acquired at the third time varies, where the third time is located after the second time, and the load level of the cell periodically acquired in the third time to the fourth time is referred to as a third load level for convenience of explanation, where a duration of the third time to the fourth time is a preset duration before the third time. And if the third load levels periodically acquired in the third time to the fourth time are equal and the third load level is different from the first load level, acquiring the scheduling priority of the UE according to the QCI and the third load level in the fourth time, and replacing the saved scheduling priority of the UE with the acquired scheduling priority.

The details of the base station acquiring the scheduling priority of the UE according to the QCI and the third load level can be found in the above-mentioned steps 204 to 205, which will not be described in detail here.

For example, referring to fig. 4, after the second time t2 to the third time t3, the base station periodically acquires the load level of the cell as a first load level, the first load level is "medium load", and in the third time t3 to the fourth time t4, the base station periodically acquires the third load level of the cell as "heavy load" and higher than the first load level "medium load", so that at the fourth time t4, the scheduling priority of the UE is acquired according to the QCI and the third load level, and the duration between the third time t3 and the fourth time t4 is a preset duration.

Step 206: when the base station schedules the UE, the base station schedules the UE according to the scheduling priority of the UE.

The base station may need to send data to the UE or the UE may need to send data to the base station. Before the base station transmits data to the UE, the base station firstly schedules the UE according to the stored scheduling priority of the UE, and the base station transmits the data to the UE after the UE is scheduled. Before the UE sends data to the base station, the UE sends a scheduling request to the base station, and after the base station receives the scheduling request, the UE is scheduled according to the stored scheduling priority of the UE, and the UE is scheduled and then sends data to the base station. Or when the base station needs to schedule the UE, the base station executes the steps 202 to 206 to obtain the scheduling priority, and schedules the UE according to the scheduling priority.

The base station sorts the UE according to the scheduling priority of the UE, and schedules the UE according to the sorted order.

In the corresponding relation between the QCI, the load level and the numerical value of the wireless dispatching parameter, the difference value between the numerical values of the wireless dispatching parameters corresponding to different QCIs is smaller when the load level of the network is lower. Under the condition that the load level of a cell is lower, the load of a network is lower, at the moment, idle resources of a base station are more, so that the difference between the values of wireless scheduling parameters corresponding to different QCIs is smaller, the obtained difference between the values of the wireless scheduling parameters of different UEs is smaller, the difference between the scheduling priorities of each UE obtained based on the values of the wireless scheduling parameters of each UE is smaller, and when each UE is scheduled according to the scheduling priorities of each UE, each UE obtains a relatively uniform scheduling opportunity, so that the QoS of the UE is improved.

In the corresponding relation among QCI, load level and wireless dispatching parameter value, under the condition that the load level of the cell is higher, the difference value between the wireless dispatching parameter values corresponding to different QCIs is larger, and the wireless dispatching parameter value corresponding to a larger QCI is far larger than the wireless dispatching parameter value corresponding to a smaller QCI. When the load level of the network is higher, the load of the network is higher, and at this time, the idle resources of the base station are smaller, so that the difference between the value of the radio scheduling parameter corresponding to the larger QCI and the value of the radio scheduling parameter corresponding to the smaller QCI is larger. The larger QCI is typically a QCI corresponding to a UE of a VIP user or a VVIP user, or is typically a QCI corresponding to a service with a high priority, so that a value of a radio scheduling parameter obtained for the VIP user or the VVIP user's UE or the UE transmitting the service with the high priority is larger, and a scheduling priority of the UE obtained based on the value of the radio scheduling parameter of the UE is also larger, so that when the UE is scheduled according to the scheduling priority of the UE, a scheduling opportunity obtained by the UE is higher, thereby improving QoS of the VIP user or the UE of the VVIP user or the UE transmitting the service with the high priority.

In the embodiment of the application, as the numerical value of the load parameter of the cell where the UE is located is obtained, the load level of the cell is obtained according to the numerical value of the load parameter, and the numerical value of the wireless scheduling parameter is obtained according to the QCI corresponding to the identity type of the UE or the service transmitted by the UE and the load level, so that the numerical value of the wireless scheduling parameter adapting to the situation is obtained under different conditions of the load of the cell, thereby obtaining the scheduling priority based on the numerical value of the wireless scheduling parameter, and improving the QoS of the UE when the UE is scheduled according to the scheduling priority. In addition, when the numerical value of the wireless dispatching parameter is acquired, the load level of the cell is periodically acquired, and when the load level acquired in a continuous period of time is the same as the load level acquired before the period of time, the dispatching priority is calculated according to the load level acquired in the period of time and the QCI, so that the dispatching priority can be prevented from being frequently calculated, and the occupation of the computing resource of the base station is reduced.
