Problems solved by technology

[0004] In the prior art, the frame structure used by each channel is pre-configured. When the channel adopts a long frame structure, if the amount of data to be scheduled is small, it is easy to affect the scheduling flexibility of the system; when the channel adopts a short frame structure , if the amount of data to be scheduled is large, it will easily lead to low spectrum utilization

Embodiment 1

[0063] An embodiment of the present invention provides a resource scheduling method, which is applied to the ground terminal of a satellite communication system, such as figure 1 shown, including:

[0064] Step 101, acquire the data volume of the data to be scheduled.

[0065] For example, when the terminal uses a satellite communication system for data transmission, if the amount of data to be transmitted is large, the data to be transmitted can be divided into multiple data packets, which are transmitted sequentially in the form of data packets to reach the destination Afterwards, the data to be scheduled can be reassembled, so the data to be scheduled can be a data packet, and the size of the data packet is the data volume of the data to be scheduled.

[0066] Step 102: Select a frame structure for scheduling the data to be scheduled according to the data volume of the data to be scheduled.

[0067] For example, if the amount of data to be scheduled is large, the long frame...

Embodiment 2

[0084]The embodiment of the present invention provides a resource scheduling method, which is applied to the ground terminal of the satellite communication system. The ground terminal is the interface between the satellite communication system and the ground public network. The terminal can also enter and exit the satellite system through the ground terminal to form a link. The ground side can also include the ground satellite control center, and its tracking, telemetry and command stations. Such as figure 2 As shown, the resource scheduling method includes:

[0085] Step 201. Receive a plurality of data to be sent to the terminal, and execute step 202.

[0086] In practical applications, there are many data interactions in the satellite communication network, and there may be multiple data packets that need to be sent at the same time, so multiple data to be sent can be obtained within a period of time.

[0087] Step 202, determine the type of each data to be sent, and exe...

Embodiment 3

[0104] The embodiment of the present invention provides a resource scheduling method, which is applied to the ground terminal of the satellite communication system. The ground terminal is the interface between the satellite communication system and the ground public network. The terminal can also enter and exit the satellite system through the ground terminal to form a link. The ground side can also include the ground satellite control center, and its tracking, telemetry and command stations. Such as image 3 As shown, the resource scheduling method includes:

[0105] Step 301. Receive a plurality of data to be sent to the terminal, and execute step 302.

[0106] Step 302, determine the type of each data to be sent, and execute step 303.

[0107] Step 303 : Determine the priority of each data to be sent according to the type of each data to be sent, and execute step 304 .

[0108] Step 304: Select the current data to be scheduled according to the priority of each data to be...

Abstract

An embodiment of the present invention provides a resource scheduling method, the method comprising: acquiring the data volume of the data to be scheduled; selecting a frame structure for scheduling the data to be scheduled according to the data volume of the data to be scheduled; according to the selected frame structure , to schedule the data to be scheduled. Further, the embodiment of the present invention also provides a resource scheduling device.

Description

technical field [0001] The present invention relates to resource allocation technology in the communication field, in particular to a resource scheduling method and device. Background technique [0002] Satellite communication is the communication that uses satellites as relays. Due to the advantages of large communication range, high reliability, rapid opening and flexible setting, satellite communication has developed rapidly in recent years. [0003] In the existing DVB-RCS standard protocol, the satellite communication system adopts Time Division Multiplexed (TDM) transmission, and each frame can only correspond to one frame structure and one modulation and coding mode. Among them, the frame structure includes two types of long frame and short frame. Under the same bandwidth configuration, the frame length of the long frame is 4 times that of the short frame. higher efficiency. From the above characteristics of the protocol, it can be seen that in the application scena...
