Description
Technical Field
The present application relates to the field of satellite communications technologies, and in particular, to a method, an apparatus, and a storage medium for transmitting data information by adjusting a virtual channel.
Background
With the continuous development of satellite communication technology, the transmission of data information by using satellites is one of the main communication modes between terminal devices. Fig. 1 is a schematic diagram of a conventional satellite transmission system. Referring to fig. 1, first, a first terminal device 100 (i.e., source terminal device) transmits data information to a first gateway station 200 through internet communication. The first gateway station 200 then transmits the data information to the satellite 300 via the first virtual channel. Further, the satellite 300 transmits data information to the second gateway station 400 through the second virtual channel. Finally, the second gateway 400 transmits the data information to the second terminal device 500 (i.e., the target terminal device) through internet communication. The above-mentioned process uses the satellite 300 to transmit data information, so that it has the characteristics of wide coverage range and high transmission rate.
However, in practice, since the satellite 300 needs to interact with the first gateway station 200 through the first virtual channel and also needs to interact with the second gateway station 400 through the second virtual channel, the time slot sizes of the first virtual channel for receiving data information and the second virtual channel for transmitting data information may be different since the first virtual channel for receiving data information and the second virtual channel for transmitting data information are two different virtual channels. In addition, since the slot size of the first virtual channel for receiving the data information and the slot size of the second virtual channel for transmitting the data information may be different, the data size of the data frame may be different from the data size of the second virtual channel.
For example, the first virtual channel may be capable of transmitting an amount of data greater than an amount of data of a data frame that is greater than an amount of data that the second virtual channel may be capable of transmitting. Thus, the utilization of the first virtual channel is reduced, and congestion occurs when data information is transmitted to the second virtual channel.
The publication number is CN114142907A, and the name is a channel screening optimization method and system of communication terminal management equipment. The method comprises the following steps: acquiring wireless radio frequency channel signals of a plurality of ground base stations; virtual channel transmission matrix mapping is carried out on the virtual partition of the ground base station based on the respective data task of the original satellite, and a source coding matrix and a channel coding matrix are obtained; based on the condition that the modulus of the signal transmission capacity of the wireless radio frequency channel is smaller than the maximum receiving power of the virtual partition and the signal-to-noise ratio strength of the wireless radio frequency channel signal is minimum; dynamic screening and channel preliminary screening of the virtual partition are realized; and obtaining the arranged priority according to the dynamic parameters, and combining with other terminals according to the priority to realize channel fine screening.
The publication number is CN114079554A, and is named as a data transmission method, a device, a communication node and a storage medium. The method comprises the steps of determining a virtual channel according to a mapping type of a resource unit, wherein the virtual channel comprises at least one of a first type channel and a second type channel; and mapping the data of the virtual channel into the corresponding resource blocks for transmission according to the mapping relation of each resource block in the range of the virtual channel and the bandwidth, wherein each resource block comprises a set number of resource units.
In view of the above-mentioned technical problems in the prior art that the size of the data amount that can be transmitted by the virtual channel for receiving the data information transmitted by the source terminal device and the size of the data amount that can be transmitted by the virtual channel for transmitting the data information to the target terminal device do not correspond to the size of the data amount of the data frame, so as to affect the utilization rate of the virtual channel and the transmission rate of the data information, no effective solution has been proposed yet.

In the above-described operating environment, according to a first aspect of the present embodiment, there is provided a method of transmitting data information by adjusting a virtual channel, the method being implemented by a processor shown in fig. 2. Fig. 5 shows a schematic flow chart of the method, and referring to fig. 5, the method includes:
S502: receiving data information transmitted by a first terminal device, and counting the data quantity of a data frame corresponding to the data information, wherein the first terminal device is used for indicating a source terminal device for transmitting the data information;
s504: receiving a first bandwidth value of a first virtual channel transmitted by the satellite and a second bandwidth value of a second virtual channel, wherein the first virtual channel represents a virtual channel for receiving data information and the second virtual channel represents a virtual channel for transmitting data information;

s512: and transmitting the data information to a second terminal device, wherein the second terminal device is used for indicating a target terminal device for receiving the data information.
Specifically, first, the application layer of the first terminal device 100 transmits data information to the transport layer. The transmission layer of the first terminal device 100 then generates a data packet according to the data information, and transmits the data packet corresponding to the data information to the network layer. Further, the network layer of the first terminal device 100 generates an IP packet according to the data packet segment corresponding to the data information, and transmits the IP packet to the link layer. Then, the link layer generates a data frame corresponding to the data information according to the IP data packet, and transmits the data frame to the link layer of the first protocol gateway 200 through the internet communication.
After the link layer of the stack (1) of the first protocol gateway 200 receives the data frame corresponding to the data information, the data frame is transmitted to the network layer of the stack (1). Further, the network layer of the stack (1) generates an IP data packet corresponding to the data information according to the data frame, and transmits the IP data packet to the network layer of the stack (2). Then, the network layer of the stack (2) transfers the IP data packet corresponding to the data information to the AOS layer of the stack (2). The AOS layer of the stack (2) generates AOS space link frames from IP data packets.
Further, a data amount statistics module in an AOS layer of the stack (2) counts data amounts of AOS spatial link frames corresponding to the data information (S502). For example, the data volume statistics module counts that the data volume of the AOS spatial link frame is 51200kb.
Further, the third information receiving module of the stack (2) of the first protocol gateway 200 receives real-time bandwidth value information (i.e., a first bandwidth value) of the first virtual channel transmitted by the first information transmitting module in the data link layer of the stack (3) of the satellite 300 and real-time bandwidth value information (i.e., a second bandwidth value) of the second virtual channel transmitted by the second information transmitting module in the data link layer of the stack (4) of the satellite 300 (S504).

The calculation formula for calculating the standard time slot information of the first virtual channel and the standard time slot information of the second virtual channel is as follows:
(equation 1)
Where Q represents the data size of the AOS spatial link frame, B represents the real-time bandwidth value of the first virtual channel or the real-time bandwidth value of the second virtual channel, and T represents the time slot of the first virtual channel (i.e., the standard time slot of the first virtual channel) or the time slot of the second virtual channel (i.e., the standard time slot of the second virtual channel) when the data size of the first virtual channel corresponds to the data size of the AOS spatial link frame.
For example, the data size of the AOS space link frame is 51200kb, the real-time bandwidth value of the first virtual channel is 1000Mps, and the real-time bandwidth value of the second virtual channel is 500Mbps, so that the standard time slot of the first virtual channel is 0.05s and the standard time slot of the second virtual channel is 0.025s according to the above formula 1.
Then, the third information transmitting module in the AOS layer of the stack (2) of the first protocol gateway 200 transmits the calculation result to the first information receiving module and the second information receiving module of the satellite 300.
Further, the first information sending module in the data link layer of the stack (3) of the satellite 300 transmits the standard time slot information corresponding to the first virtual channel to the first channel adjusting module; the second information sending module in the data link layer of the stack (4) of the satellite 300 transmits the standard time slot information corresponding to the second virtual channel to the second channel adjustment module.
The first channel adjusting module adjusts the time slot of the first virtual channel according to the standard time slot information corresponding to the first virtual channel; the second channel adjustment module adjusts the time slot of the second virtual channel according to the standard time slot information corresponding to the second virtual channel (S508).
Fig. 6 shows a comparison of the time slots of the first virtual channel and the time slots of the second virtual channel before adjustment and after adjustment. Referring to fig. 6, before the time slots of the first virtual channel and the time slots of the second virtual channel are not adjusted, the time slots of the first virtual channel are larger than the time slots of the second virtual channel. After the time slots of the first virtual channel and the time slots of the second virtual channel are adjusted, the time slots of the first virtual channel are smaller than the time slots of the second virtual channel. And the time slot size of the first virtual channel corresponds to the standard time slot of the first virtual channel (i.e., the data size that the first virtual channel can transmit corresponds to the data size of the AOS spatial link frame); the slot size of the second virtual channel corresponds to the standard slot size of the second virtual channel (i.e., the data size that the second virtual channel can transmit corresponds to the data size of the AOS spatial link frame).
Then, the first protocol gateway 200 responds to the feedback information transmitted by the satellite 300, which has been adjusted for the first virtual channel and the second virtual channel, and transmits the AOS space link frame corresponding to the data information to the satellite 300 through the first virtual channel.
Further, satellite 300 transmits data link frames corresponding to the AOS space link frames to second protocol gateway 400 via a second virtual channel.
The second protocol gateway 400 generates an AOS space link frame after receiving the data link frame corresponding to the data information, and transmits the AOS space link frame to the second terminal device 500 through internet communication.
As described in the background art, in actual practice, since the satellite 300 needs to interact with the first gateway station 200 through the first virtual channel and also needs to interact with the second gateway station 400 through the second virtual channel, the time slot sizes of the first virtual channel for receiving data information and the second virtual channel for transmitting data information may be different because of two different virtual channels when the first virtual channel for receiving data information and the second virtual channel for transmitting data information are received. Also, since the slot size of the first virtual channel for receiving data information and the slot size of the second virtual channel for transmitting data information may be different, the data size that the first virtual channel can transmit and the data size that the second virtual channel can transmit may be different from the data size of the data frame.
For example, the first virtual channel may be capable of transmitting an amount of data greater than an amount of data of a data frame that is greater than an amount of data that the second virtual channel may be capable of transmitting. Thus, the utilization rate of the first virtual channel is reduced, and the data information is blocked when being transmitted to the second virtual channel.
In view of this, in the embodiment of the present application, since the first protocol gateway 200 counts the data amount of the data frame corresponding to the data information in advance and receives the first bandwidth value of the first virtual channel and the second bandwidth value of the second virtual channel transmitted by the satellite 300, the first protocol gateway 200 can calculate the standard time slot corresponding to the first virtual channel and the standard time slot corresponding to the second virtual channel. The standard time slot of the first virtual channel is a time slot corresponding to the data size of the data frame and the data size which can be transmitted by the first virtual channel; the standard time slot of the second virtual channel is a time slot corresponding to the data size of the data frame and the data size of the data size that can be transmitted by the second virtual channel.
Further, the satellite 300 adjusts the time slot size of the first virtual channel and the time slot size of the second virtual channel according to the standard time slot corresponding to the first virtual channel and the standard time slot corresponding to the second virtual channel, respectively. So that the time slot size of the first virtual channel corresponds to the standard time slot of the first virtual channel and the time slot size of the second virtual channel corresponds to the standard time slot of the second virtual channel. Thus, when the first protocol gateway 200 transmits the data frame corresponding to the data information to the second protocol gateway 400 through the first virtual channel and the second virtual channel corresponding to the satellite 300, the utilization ratio of the first virtual channel and the second virtual channel and the transmission efficiency of the data information are not affected. The method further solves the technical problems that in the prior art, the size of the data quantity which can be transmitted by the virtual channel for receiving the data information transmitted by the source terminal device and the size of the data quantity which can be transmitted by the virtual channel for transmitting the data information to the target terminal device do not correspond to the size of the data quantity of the data frame, so that the utilization rate of the virtual channel and the transmission rate of the data information are affected.
Optionally, the operation of adjusting the time slot of the first virtual channel to correspond to the standard time slot of the first virtual channel includes: judging whether the time slot of the first virtual channel corresponds to the standard time slot of the first virtual channel; under the condition that the time slot of the first virtual channel corresponds to the standard time slot of the first virtual channel, not adjusting the time slot of the first virtual channel; and adjusting the time slot of the first virtual channel to be equal to the standard time slot of the first virtual channel under the condition that the time slot of the first virtual channel does not correspond to the standard time slot of the first virtual channel.
Specifically, before the first channel adjustment module in the data link layer of the satellite 300 adjusts the time slot of the first virtual channel, it needs to be determined in advance whether the time slot of the first virtual channel corresponds to the standard time slot of the first virtual channel (i.e., whether the size of the data volume that can be transmitted by the first virtual channel corresponds to the size of the data volume of the data link frame before the first virtual channel is not adjusted).
Under the condition that the time slot of the first virtual channel is judged to correspond to the standard time slot of the first virtual channel, the time slot of the first virtual channel does not need to be adjusted; and when the time slot of the first virtual channel is judged not to correspond to the standard time slot of the first virtual channel, adjusting the time slot of the first virtual channel. For example, if the time slot size of the first virtual channel is smaller than the standard time slot size of the first virtual channel, the time slot of the first virtual channel needs to be enlarged, so that the time slot of the first virtual channel is equal to the standard time slot of the first virtual channel; if the time slot size of the first virtual channel is larger than the standard time slot size of the first virtual channel, the time slot of the first virtual channel needs to be reduced, so that the time slot of the first virtual channel is equal to the standard time slot of the first virtual channel.
Optionally, the operation of adjusting the time slot of the second virtual channel to correspond to the standard time slot of the second virtual channel includes: judging whether the time slot of the second virtual channel corresponds to the standard time slot of the second virtual channel; under the condition that the time slot of the second virtual channel corresponds to the standard time slot of the second virtual channel, not adjusting the time slot of the second virtual channel; and adjusting the time slot of the second virtual channel to be equal to the standard time slot of the second virtual channel under the condition that the time slot of the second virtual channel does not correspond to the standard time slot of the second virtual channel.
Specifically, before the second channel adjustment module in the data link layer of the satellite 300 adjusts the time slot of the second virtual channel, it needs to be determined in advance whether the time slot of the second virtual channel corresponds to the standard time slot of the second virtual channel (i.e., whether the size of the data volume that can be transmitted by the second virtual channel corresponds to the size of the data volume of the data link frame before the second virtual channel is not adjusted).
Under the condition that the time slot of the second virtual channel is judged to correspond to the standard time slot of the second virtual channel, the time slot of the second virtual channel does not need to be adjusted; and when the time slot of the second virtual channel is judged not to correspond to the standard time slot of the second virtual channel, adjusting the time slot of the second virtual channel. For example, if the time slot size of the second virtual channel is smaller than the standard time slot size of the second virtual channel, the time slot of the second virtual channel needs to be enlarged, so that the time slot of the second virtual channel is equal to the standard time slot of the second virtual channel; if the time slot size of the second virtual channel is larger than the standard time slot size of the second virtual channel, the time slot of the second virtual channel needs to be reduced, so that the time slot of the second virtual channel is equal to the standard time slot of the second virtual channel.
Optionally, the operation of receiving the first bandwidth value of the first virtual channel and the second bandwidth value of the second virtual channel transmitted by the satellite includes: monitoring a first bandwidth value of a first virtual channel in real time; monitoring a second bandwidth value of a second virtual channel in real time; and transmitting the first bandwidth value of the first virtual channel and the second bandwidth value of the second virtual channel to the first protocol gateway.
Specifically, a first channel adjustment module in the data link layer of the stack (3) of the satellite 300 monitors the real-time bandwidth value of the first virtual channel in real-time; a second channel adjustment module in the data link layer of the stack (4) of the satellite 300 monitors the real-time bandwidth value of the second virtual channel in real-time.
Then, the first channel adjusting module in the data link layer of the stack (3) of the satellite 300 transmits the real-time bandwidth value of the first virtual channel to the first information transmitting module; the second channel adjustment module in the data link layer of the stack (4) of the satellite 300 transmits the real-time bandwidth value of the second virtual channel to the second information transmission module.
Finally, the first information sending module in the data link layer of the stack (3) of the satellite 300 transmits the real-time bandwidth value of the first virtual channel to the third information receiving module in the first protocol gateway 200; the second information sending module in the data link layer of the stack (4) of the satellite 300 transmits the real-time bandwidth value of the second virtual channel to the third information receiving module in the first protocol gateway 200.
Thus, according to the first aspect of the present embodiment, when the first protocol gateway 200 transmits the data frame corresponding to the data information to the second protocol gateway 400 through the first virtual channel and the second virtual channel corresponding to the satellite 300, the utilization ratio of the first virtual channel and the second virtual channel and the transmission efficiency of the data information are not affected. The method further solves the technical problems that in the prior art, the size of the data quantity which can be transmitted by the virtual channel for receiving the data information transmitted by the source terminal device and the size of the data quantity which can be transmitted by the virtual channel for transmitting the data information to the target terminal device do not correspond to the size of the data quantity of the data frame, so that the utilization rate of the virtual channel and the transmission rate of the data information are affected.
Further, referring to fig. 2, according to a second aspect of the present embodiment, there is provided a storage medium. The storage medium includes a stored program, wherein the method of any one of the above is performed by a processor when the program is run.
Thus, according to the present embodiment, when the first protocol gateway 200 transmits the data frame corresponding to the data information to the second protocol gateway 400 through the first virtual channel and the second virtual channel corresponding to the satellite 300, the utilization ratio of the first virtual channel and the second virtual channel and the transmission efficiency of the data information are not affected. The method further solves the technical problems that in the prior art, the size of the data quantity which can be transmitted by the virtual channel for receiving the data information transmitted by the source terminal device and the size of the data quantity which can be transmitted by the virtual channel for transmitting the data information to the target terminal device do not correspond to the size of the data quantity of the data frame, so that the utilization rate of the virtual channel and the transmission rate of the data information are affected.
