The embodiments of the present disclosure can study the operation requirements of the satellite communication carrier and the requirements of the full service of the individual user, and adopt the end station group, the individual user, and the service to perform the QoS scheduling at three levels divided into multiple policies.

The first level is for the end station group, and the end station group may be the minimum bandwidth service range provided by the satellite communication operator for its multiple agents, and each agent is assigned an end station group, and the end station group may include the belonging agent. End station. The end station group can also represent a virtual carrier.

Each end station group (such as the first end station group) can configure the specified air interface resource ratio and can formulate a policy to allow the end station group to overuse the configured air interface resources. When the set policy is not allowed to be oversubscribed, each end station group can only use its configured air interface resource ratio; when the set policy is to allow oversubscription, and when other end station groups actually need less bandwidth, Therefore, when there is a remaining air interface resource, the busy end station group can allocate more air interface resources than the allocated air interface resource ratio, so as to fully use the air interface resource to maximize the total system throughput. When the network is congested, the proportion of air interface resources configured by each end station group is not allowed to be used by other end station groups unless the actual required bandwidth of some end station groups is less than the corresponding air interface resource proportion.

The second level sets the secondary scheduling policy of each end station group and the QoS configuration of the level, which can be scheduled by individual users or by end station scheduling.

When the second level setting is scheduled for individual users, unified scheduling is performed for all individual users under the first end station group. Within the proportion of the air interface resources configured by the first end station group, all individual users in the first end station group may be scheduled according to the Qos requirement configured for the individual user, and the individuals in the first end station group are satisfied. User's QoS fairness. For the scheduling mode in each end station group, refer to the scheduling mode of all individual users in the cell level of the traditional terrestrial cellular communication, and details are not described herein.

When the second level setting is for end station scheduling, that is, all the end stations under one end station group (such as the first end station group) are uniformly scheduled, instead of performing unified scheduling for all users in the end station group. Under this strategy, the corresponding Qos configuration can be set for each end station in the end station group. The scheduling mode in each end station group can refer to the individual user scheduling mode in the traditional terrestrial cellular communication cell level, and treat the individual users in the traditional communication as the end station, and will not be described here.

The third level sets the QoS of the service. Correspondingly, the third level can also be changed according to the strategy of the second level.

When the second level is scheduled for individual users, the third level may be for different services within the individual user, for different application service types under a certain individual user under a certain end station group (such as the first end station group), according to the individual The requirements of the QoS configuration of different services of the user are scheduled to implement the QoS fairness of different services of the individual user. For the scheduling mode of different services for individual users, refer to the different service scheduling modes of the traditional terrestrial cellular communication individual users, and details are not described herein.

When the second level is scheduled for the end station, the third level may be configured for different services within the end station group (such as the first end station group), similar to different services within the individual user, and configured and scheduled according to the service. Let me repeat.

Optionally, referring to FIG. 3, the configuration module 202 may include: an end station group configuration module, an individual user configuration module, an end station configuration module, and a service configuration module. The scheduling module 203 may include: an air interface resource scheduling module and an air interface resource total allocation. Modules, etc. Referring to FIG. 4, the QoS scheduling based on the optional module in FIG. 3 may include the following steps:

The end station group configuration module can set an end station group for each agent according to the bandwidth requirement of the operator to all agents, and divide the air port resource occupation ratio for each agent in the spectrum range. Optionally, the total proportion of the air interface resources occupied by all agents cannot exceed the proportion of the remaining resources of the total spectrum except the necessary system public expenses.

S401.1, develop an end-use group over-use strategy. It can be set for each end station group: when the actual service demand bandwidth of the end station group (such as the first end station group) is large, and the actual service demand bandwidth of other end station groups is smaller than the configured air interface occupation ratio, End station groups can be configured to be oversubscribed or not oversubscribed.

In S401.2, the end station group (such as the first end station group) selects the individual user or the end station as the second level scheduling node.

S402. Set a second level scheduling node. You can set each end station group to select individual users or select end stations, and set individual user or end station Qos attributes.

S402.1, when S401.2 selects an individual user as the second-level scheduling node, set it as follows. The personal user configuration module can set the industry-standard Qos attribute for the individual user according to the operator's Qos configuration policy, which can include attributes such as user level and information bandwidth rate. And configure the end user group (such as the first end station group) to which the individual user belongs.

S402.2, when S401.2 selects the end station as the second level scheduling node, set as follows. The end station configuration module can set the industry-standard Qos attribute for the end station according to the operator's end station QoS configuration policy, which can roughly include attributes such as end station level and information bandwidth rate. The end station group to which it belongs (for example, the first end station group) can be configured.

S403, setting a third level Qos attribute.

The service configuration module can set the industry-specific Qos attributes for different service applications according to the service QoS configuration policy of the service provider, and can include attributes such as service level, information bandwidth rate, and delay sensitivity.

S404. The end station group air interface resource scheduling module runs multiple instances, and each instance independently performs end station group scheduling for one of the end station groups.

S404.1, when S401.2 selects an individual user as the second hierarchical scheduling node, in the end station group, according to the individual users in the end station group that are connected to the satellite network and belong to the end station group and The service application requires bandwidth allocation and configuration according to the industry's usual QoS scheduling mode. The scheduling unit can be a personal user-level service flow, and each service flow is an application flow for each individual user using a specific type of service. The to-be-scheduled may be various service flows of all individual users under the end station group. The MAC layer frame required for the physical layer group physical frame can be generated according to the satellite communication protocol, and is cached in the local station group MAC frame queue.

S404.2, when the S401.2 selects the end station as the second level scheduling node, in the end station group, according to the end station in the end station group that is connected to the satellite network and belongs to the end station group and The bandwidth requirements and configuration of the service application are allocated according to the industry's usual QoS scheduling mode. The scheduling unit may be an end-station-level service flow, and each service flow uses the same type by multiple individual users on the end station. The application service flows are aggregated, and the various service flows of all end stations under the end station group may be scheduled to be scheduled. The MAC layer frame required for the physical layer group physical frame can be generated according to the satellite communication protocol, and is cached in the local station group MAC frame queue.

S405. The air interface resource total allocation module performs scheduling between the end station groups.

The air interface resource total allocation module may take the corresponding MAC frame from each end station group MAC frame queue according to the air interface resource occupation ratio configured by each end station group, and submit the physical layer to perform physical layer framing. When the bandwidth of the actual service requirement of one of the end station groups (such as the first end station group) exceeds the proportion of the air interface resources allocated by the other end station group, and the current actual service demand bandwidth of the other end station group is smaller than the proportion of the air interface resources allocated by the end station group, According to the over-use policy of S401.1, it can be used excessively for the end station group, or the air interface resources are not used excessively.
