Description

Technical Field

[0001] The present invention relates to the field of satellite communication technology, and in particular to a power distribution method, device, electronic equipment and computer-readable storage medium. Background Art

[0002] Frequency Division Multiple Access (FDMA), one of the earliest and most widely adopted multiple access technologies in satellite communication systems, is based on the principle of dividing the available spectrum into multiple non-overlapping sub-bands, each allocated to different users or terminals, thereby enabling multi-user sharing of satellite communication resources. In FDMA-based satellite communication systems, the ground master station typically coordinates and manages the entire network through a network management center (referred to as the master station network management center). Specifically, the master station network management center sends control signaling to each terminal via the master station modulator and receives status feedback from each terminal via the master station demodulator. This allows for monitoring terminal operating status and the optimal allocation of satellite resources.

[0003] Currently, traditional satellite communication terminals generally use a hardware architecture with a single transmit channel (TX) and a single receive channel (RX). Once connected to the master station network management system, when there is no need to transmit large amounts of service data, the terminal maintains state interaction with the master station network management system through the transmit and receive channels to maintain network connectivity and report operating status. However, when service data (such as video streams and large files) needs to be transmitted, the terminal typically disconnects the communication link with the master station network management system and switches the operating parameters of the transmit channel (such as frequency, symbol rate, roll-off factor, etc.) to establish a new communication link with the target terminal for data transmission. However, this traditional mechanism has the following technical problems:

[0004] First, because the terminals only have a single transmit and receive channel, switching to inter-terminal communication requires interrupting the exchange of status information with the master network management system. This limits the real-time monitoring capabilities of the network management system and may affect the overall stability and maintainability of the network.

[0005] Secondly, in an FDMA network, terminals and the master network management station typically only need to transmit a small amount of status information, requiring lower communication quality and a low transmit power. However, inter-terminal communication, due to the large data volume and high transmission efficiency requirements, typically requires the use of higher-order modulation and coding schemes. To ensure communication quality, operators often need to manually increase the transmit power, which not only increases operational complexity but also easily wastes power resources or causes adjacent channel interference, impacting overall system performance. Summary of the Invention

[0065] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0066] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0067] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0068] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0069] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0070] Introduction to the professional names or terms involved in the present invention:

[0071] 1. Single Channel Per Carrier (SCPC): Single Channel Per Carrier technology is a transmission technology used in satellite communications. Its core feature is that each carrier carries only one independent communication signal (such as voice, data, or video).

[0072] 2. Point-to-point SCPC: Two terminals communicate one-to-one through a dedicated carrier, rather than sending data to multiple recipients at the same time as broadcast or multicast.

[0073] The application scenarios of the present invention are first introduced here.

[0074] like Figure 1 In the satellite networking system shown, the master station network manager manages the first terminal and the second terminal via the satellite, and the first terminal and the second terminal communicate with each other via the satellite.

[0075] The first terminal and the second terminal may be a satellite communication terminal, such as a vehicle-mounted satellite terminal, a ship-mounted satellite terminal, an aircraft-mounted satellite terminal, a fixed station, an IoT (Internet of Things) device, etc.

[0076] Among them, such as Figure 2 , the first terminal and the second terminal each include two transmission channels ( Figure 2 TX1, TX2) and two receiving channels ( Figure 2 Each channel operates independently without interfering with each other. TX1 and RX1 are primarily used to maintain status with the master network management station, while service data transmission and status exchange between the first and second terminals are primarily achieved through TX2 and RX2.

[0077] In satellite communication systems, the terminal's antenna power amplifier is a critical component for ensuring signal transmission quality. It amplifies the transmitted signal's power to a sufficient level to overcome attenuation during propagation and ensure stable signal transmission to the receiving end. However, exceeding the amplifier's maximum rated power can cause a range of problems, such as amplifier saturation, signal distortion, and power supply overload. To avoid these problems, strict control of input power is essential, ensuring that the amplifier operates within a safe range.

[0078] The power distribution method provided by the embodiment of the present invention can be applied to Figure 1The first terminal includes a first transmitting channel, a first receiving channel, a second transmitting channel, and a second receiving channel. The present invention can be applied to scenarios where antenna power amplification is limited. By adaptively adjusting the power of the dual transmitting channels, the present invention simultaneously ensures stable status of the terminal and the network management system, and efficient transmission of SCPC services between terminals.

[0079] in, Figure 1 The illustration is for illustrative purposes only. The second terminal that transmits service data with the first terminal may also be a single-transmitting / receiving channel terminal. When the second terminal has dual-transmitting / receiving channels, the process for the second terminal to access the master station network management and the process for adjusting the power of the two transmitting channels are logically consistent with the power allocation method provided in the embodiment of the present invention. The power allocation method provided in the embodiment of the present invention is described below only from the perspective of the first terminal.

[0080] like Figure 3 , the power allocation method comprises the following steps:

[0081] S101: After initializing and setting a first receiving channel, monitor forward broadcast signaling periodically sent by a master station network manager through the first receiving channel.

[0082] In this embodiment, the first receive channel is initialized to ensure that the forward broadcast signaling periodically sent by the master station network management can be effectively monitored through the first receive channel. The initialization settings may include configuring the local oscillator (LO) parameters of the outdoor unit (ODU), such as the LNB (Low Noise Block Downconverter) and BUC (Block Upconverter) LO frequencies, and configuring receive parameters such as the intermediate frequency (IF), symbol rate, and roll-off factor.

[0083] S102: Based on the forward broadcast signaling, interact with the master station network management through the first sending channel and the first receiving channel to access the satellite network.

[0084] S103: After successful network access, configure the second sending channel and the second receiving channel based on the service carrier number of the resource allocation table and the service carrier information in the resource information table in the latest monitored forward broadcast signaling, so that the first terminal supports SCPC service transmission.

[0085] After successfully joining the network, the first terminal will configure the second transmit channel and the second receive channel based on the service carrier number in the resource allocation table and the service carrier information in the resource information table in the most recently monitored forward broadcast signaling. This configuration process includes searching for parameters such as the corresponding frequency, symbol rate, and roll-off factor based on the service carrier number, and setting the operating mode of the second transmit channel and the second receive channel accordingly. Through this configuration, the first terminal has the ability to support SCPC service transmission, thereby enabling it to establish a point-to-point data communication link with other terminals.

[0086] S104 : After successfully joining the network, periodically perform state-maintaining interaction with the master station network management through the first transmitting channel and the first receiving channel, and dynamically adjust the first transmitting power of the first transmitting channel during each state-maintaining interaction.

[0087] S105 . During SCPC service transmission with the second terminal, periodically exchange states with the second terminal through the second transmitting channel and the second receiving channel, and dynamically adjust the second transmitting power of the second transmitting channel during each state exchange.

[0088] During the SCPC service transmission process with the second terminal, the first terminal sends and receives service data through the second sending channel and the second receiving channel, and exchanges status with the second terminal.

[0089] In the power allocation method provided in an embodiment of the present invention, a first terminal utilizes dual transmit and receive channels. After accessing the master station network management system, the first set of transmit and receive channels is used to maintain state with the master station network management system, while the second set of transmit and receive channels is used to transmit services with the second terminal. Furthermore, the transmit power of the first transmit channel is dynamically adjusted during each state preservation interaction. During service transmission, each time the two terminals exchange states, the second transmit channel is also dynamically adjusted. Compared to the prior art, the present invention utilizes dual transmit and receive channels, eliminating the need to disconnect from the master station network management system even during service transmission. Furthermore, the transmit power of the two transmit channels can be automatically and dynamically adjusted, eliminating the need for manual power setting, thus achieving efficient utilization of power resources.

[0090] In an optional implementation, the implementation of step S102 includes S1021 to S1024.

[0091] S1021 extracts return carrier parameters and access time slot information from the forward broadcast signaling, and sets the first transmission channel based on the return carrier parameters;

[0092] In this embodiment, the return carrier parameters are the physical layer configuration parameters required by the terminal to send uplink control signals to the master station network management, including but not limited to frequency, symbol rate, and roll-off factor. The access slot information indicates the time window in which the terminal can initiate random access. This time window is centrally planned by the master station network management to avoid conflicts caused by multiple terminals accessing at the same time. The first terminal initializes the first transmission channel based on the return carrier parameters to ensure that it can transmit signals according to the specified frequency, bandwidth, and modulation method.

[0093] S1022: Based on the access time slot information, initiate a login request to the master station network manager via the first sending channel in a random access manner.

[0094] In this embodiment, after completing the parameter configuration for the first transmission channel, the first terminal initiates a login request to the master station network manager via the first transmission channel using a random access mechanism based on the time indicated by the access slot information. This random access mechanism allows a terminal to attempt to access the network in a non-reservation mode, thereby improving access efficiency and reducing system overhead. Upon receiving and demodulating the login request, the master station network manager's master demodulator returns a login response to the first terminal.

[0095] During the access process, the transmit power of the first transmit channel (hereinafter referred to as the first transmit power) can be initially configured to a relatively low value. After a login request is issued, the first terminal waits for a login response signal from the master station network management system via the first receive channel. If no login response is received within a fixed time period (e.g., 1 second), the first transmit power is increased (up to the first terminal's total transmit power) and the login request is re-initiated until a login response is received. Upon receiving a login response, the first transmit power is the minimum transmit power required for the first terminal to access the master station network management system, and can be determined as the first lower limit of the first transmit power.

[0096] If the login response is successfully received, it indicates that the master station network management has recognized the existence of the terminal and is ready to enter the next stage of the identity verification process.

[0097] S1023. After receiving the login response returned by the master station network manager through the first receiving channel, initiate an authentication request to the master station network manager through the first sending channel, so that the master station network manager performs verification based on the authentication request and returns an authentication response after the verification passes.

[0098] In this embodiment, after the first terminal receives the login response via the first receiving channel, it continues to send an authentication request to the master station network manager via the first transmitting channel. This authentication request includes the terminal's identity information and related authentication parameters. Upon receiving this request, the master station network manager verifies it to determine whether the terminal has legal access rights. If the verification passes, the master station network manager returns an authentication response signal to the first terminal, confirming its identity and allowing it to officially access the satellite network.

[0099] S1024: When the authentication response returned by the master station network manager is received through the first receiving channel, it is determined that the satellite network is successfully accessed.

[0100] In this embodiment, after the first terminal successfully receives the authentication response through the first receiving channel, it determines that the access operation has been completed and can enter the subsequent state holding and service transmission phase.

[0101] Optionally, after executing the above step S103, the first terminal can set a lower power value for the second transmission power of the second transmission channel, and then send test data to the second terminal. If the RX2 of the second terminal demodulates the received data to obtain the test data, it will return a test response to the first terminal.

[0102] Therefore, after sending a login request, the first terminal waits for a test response from the second terminal via the second receiving channel. If no test response is received within a fixed time period (e.g., 1 second), the first terminal increases the second transmit power and retransmits test data until a test response is received. Upon receiving the test response, the second transmit power is the minimum transmit power at which the second terminal can just demodulate the data, and this power can be determined as the second lower limit of the second transmit power.

[0103] In an optional implementation, the dynamic adjustment range of the first transmit power is from a first lower power limit to a first upper power limit, and the dynamic adjustment range of the second transmit power is from a second lower power limit to a second upper power limit. These two dynamic adjustment ranges ensure that the sum of the actual transmit powers of the first transmit channel and the second transmit channel does not exceed the total transmit power of the first terminal.

[0104] The first lower power limit is the minimum transmit power when the first terminal accesses the master station network management, and can be determined during the process of the first terminal accessing the master station network management. The second lower power limit is the minimum transmit power that enables the second terminal to demodulate data, and can be determined by sending multiple test data before service transmission with the second terminal.

[0105] The first upper limit power and the second upper limit power can be allocated proportionally based on the bandwidth allocated to the two transmission channels by the master station network management. That is, the first upper limit power and the second upper limit power are calculated as follows:

[0106]

[0107] Where, are the first upper limit power and the second upper limit power, is the total transmit power, is the preset priority factor ( The default size is 1, and can be adjusted by the user). The bandwidths configured by the master station network manager for the first and second sending channels respectively.

[0108] Therefore, the dynamic adjustment range of the two sending channels satisfies:

[0109] (1) First lower power limit With the second lower limit power The sum is less than the total transmit power of the first terminal ,Right now: ;

[0110] (2) The sum of the first upper limit power and the second upper limit power is equal to the total transmit power of the first terminal, that is: ;

[0111] (3) The ratio of the first upper limit power to the second upper limit power is equal to the product of the ratio of the bandwidths of the two transmission channels and the priority factor, that is: .

[0112] Based on the two dynamic adjustment ranges, the power adjustment of the two transmission channels is introduced below.

[0113] Regarding the above step S104, combined with Figure 4 The state of the communication link between the first terminal and the master station network management is maintained by the master station network management periodically sending a state request to the first terminal. That is, the implementation of step S104 includes S1041~S1043:

[0114] S1041. Receive a status request periodically sent by the master station network manager through a first receiving channel;

[0115] S1042. After receiving each status request, return a status response to the master station network manager via the first sending channel;

[0116] S1043: After each status request is received, obtain the latest received signal-to-noise ratio from the status request, and dynamically adjust the first transmit power based on the management reference signal-to-noise ratio, the first lower power limit, the first upper power limit, and the latest received signal-to-noise ratio obtained from the forward broadcast signaling.

[0117] The latest received signal-to-noise ratio is determined when the master station network management demodulates the previous status response. Figure 2The receiving channel (RX) of the master station network manager receives the status request, and then the master station demodulator demodulates the status request to determine a receiving signal-to-noise ratio. The receiving signal-to-noise ratio can reflect the quality of the wireless communication link between the first terminal and the master station network manager. Then the master station network manager writes the receiving signal-to-noise ratio into the next status request, which is modulated by the master station modulator and sent to the first terminal through the transmitting channel (TX).

[0118] Optionally, the forward broadcast signaling also includes a management reference signal-to-noise ratio, which represents the target receiving signal-to-noise ratio level that the master station network manager expects the first terminal to achieve when sending data, and the first lower limit power and the first upper limit power respectively limit the lowest and highest boundaries of the adjustable first transmission power, to prevent communication failure caused by too low power or interference caused by too high power.

[0119] Therefore, in step S1043, the dynamic adjustment process represented by "dynamically adjusting the first transmit power based on the management reference signal-to-noise ratio obtained from the forward broadcast signaling, the first lower power limit, the first upper power limit, and the latest received signal-to-noise ratio" may include the following steps:

[0120] a1. Calculate the difference between the management reference signal-to-noise ratio and the latest received signal-to-noise ratio to obtain a first difference;

[0121] a2. If the first difference is positive and the absolute value of the first difference is greater than a preset difference threshold, increase the first transmit power by a preset step size;

[0122] a3. If the first difference is positive and the absolute value of the first difference is less than or equal to the gap threshold, keep the first transmit power unchanged;

[0123] a4. If the first difference is positive and the first transmit power is equal to the first upper limit power, keep the first transmit power unchanged;

[0124] a5. If the first difference is negative and the absolute value of the first difference is greater than a preset difference threshold, reduce the first transmit power by a preset step size;

[0125] a6. If the first difference is negative and the absolute value of the first difference is less than or equal to the gap threshold, keep the first transmit power unchanged;

[0126] a7. If the first difference is negative and the first transmit power is equal to the first lower limit power, keep the first transmit power unchanged.

[0127] The receive signal-to-noise ratio (SNR) directly impacts key performance indicators of a communication system, such as bit error rate, throughput, and connection stability. A high SNR indicates good signal quality at the master station, and the terminal's current transmit power is likely within a reasonable range or even slightly higher. Conversely, a low SNR indicates significant link attenuation or strong interference, and the terminal should consider increasing its transmit power to ensure communication quality.

[0128] For example, the first transmission power is recorded as , the master station network management determines the latest received signal-to-noise ratio as SNR1, the management reference signal-to-noise ratio as Smng, the first difference = Smng-SNR1 = Δ1, assuming the preset difference threshold is 1dB. Then it can be seen from steps a1 to a7 that during the state maintenance process, for the first transmission power The adjustment strategy is:

[0129] If Δ1>0 and Δ1 is greater than 1dB, it indicates that the current received signal-to-noise ratio is much lower than Smng, and the first terminal will The transmit power is gradually increased according to the preset step size (the preset step size can be 1dBm or 2dBm) to enhance the transmission power and thus improve the demodulation performance of the receiving end. When the absolute value of Δ1 is less than 1dB during a subsequent state preservation process, it is considered that the current reception quality is close to the target and the transmission power adjustment is stopped;

[0130] If Δ1>0 and , then the power is no longer increased even if there is still a positive deviation, to avoid exceeding the hardware limit or causing interference;

[0131] If Δ1 < 0 and the absolute value of Δ1 exceeds 1 dB, it means that the current received signal-to-noise ratio is higher than Smng (there is power waste), the first terminal will start to The transmit power is gradually reduced according to the preset step size to save power and reduce interference to other users. When the absolute value of Δ1 is less than 1dB in a subsequent state saving process, it is considered that the current reception quality is close to the target and the transmit power adjustment is stopped.

[0132] If Δ1 < 0 and the absolute value of Δ1 is within 1 dB, the current power is maintained unchanged;

[0133] If Δ1<0 and , and the power will no longer be reduced to ensure basic communication capabilities.

[0134] Therefore, in the process of maintaining the state between the first terminal and the master station network management, the present invention controls the first transmission power Dynamically adjust to keep it always and Under the premise of ensuring the communication quality between the first terminal and the master station network management, unnecessary power consumption is reduced and energy consumption is lowered.

[0135] For the above step S105, combined with Figure 4 The state exchange between the first terminal and the second terminal is achieved by periodically sending state information to each other. That is, the implementation of step S105 includes S1051~S1053:

[0136] S1051. Periodically send status information to the second terminal through the second sending channel;

[0137] S1052. Receive status information periodically sent by the second terminal through the second receiving channel;

[0138] S1053. After receiving the status information each time, obtain the latest received signal-to-noise ratio from the received status information, and dynamically adjust the second transmit power based on the service reference signal-to-noise ratio, the second lower power limit, the second upper power limit, and the latest received signal-to-noise ratio obtained from the forward broadcast signaling.

[0139] The latest received signal-to-noise ratio is determined when the second terminal demodulates the last state information it received. Figure 2 The second terminal receives a status message through RX2 and demodulates it to determine a received signal-to-noise ratio. The received signal-to-noise ratio can reflect the quality of the wireless communication link between the first terminal and the second terminal. Then the second terminal writes the received signal-to-noise ratio into the next status message, modulates it, and sends it to the first terminal through TX2.

[0140] Optionally, the forward broadcast signaling also includes a service reference signal-to-noise ratio (SSR). This management reference SSR represents the target receive SNR level that the master station network administrator expects inter-terminal communication quality to achieve, ensuring that data transmission between terminals meets certain quality of service requirements. The second lower power limit and the second upper power limit respectively define the lowest and highest limits for the adjustable second transmit power, preventing communication failures caused by too low a power level or interference caused by too high a power level. Thus, the dynamic adjustment process in step S1053 essentially compares the actual receive quality of the current link with the target expected value, and decides whether to adjust the transmit power and the adjustment amount based on the size and direction of the deviation.

[0141] Specifically, in step S1053, the dynamic adjustment process represented by "dynamically adjusting the second transmit power based on the service reference signal-to-noise ratio, the second lower power limit, the second upper power limit, and the latest received signal-to-noise ratio obtained from the forward broadcast signaling" may include the following steps:

[0142] b1. Calculate the difference between the service reference signal-to-noise ratio and the latest received signal-to-noise ratio to obtain a second difference;

[0143] b2. If the second difference is positive and the absolute value of the second difference is greater than the preset difference threshold, increase the second transmit power by a preset step size;

[0144] b3. If the second difference is positive and the absolute value of the second difference is less than or equal to the gap threshold, keep the second transmit power unchanged;

[0145] b4. If the second difference is positive and the second transmit power is equal to the second upper limit power, keep the second transmit power unchanged;

[0146] b5. If the second difference is negative and the absolute value of the second difference is greater than the preset difference threshold, reduce the second transmit power by a preset step size;

[0147] b6. If the second difference is negative and the absolute value of the second difference is less than or equal to the gap threshold, keep the second transmit power unchanged;

[0148] b7. If the second difference is negative and the second transmit power is equal to the second lower limit power, keep the second transmit power unchanged.

[0149] The power adjustment in steps b1 to b7 is to ensure the communication quality of the service data sent from the first terminal to the second terminal. The specific implementation principle is consistent with the implementation principle of the above steps a1 to a7 and will not be repeated here.

[0150] Therefore, the present invention performs steps b1 to b7 to adjust the second transmission power each time the first terminal and the second terminal exchange states. Dynamically adjust to keep it always and Under the premise of ensuring the communication quality between the first terminal and the second terminal, unnecessary power consumption is reduced and energy consumption is lowered.
