First, an application scenario of the embodiment of the present application will be briefly described.
The embodiment of the application can be applied to an on-board satellite communication system. As shown in fig. 1, the on-board satellite communication system is located on an intelligent ship, and may include an on-board Ka high-flux satellite communication terminal, an on-board C-band large-beam satellite communication terminal, an on-board satellite intelligent sensing and switching gateway device, a data/instruction device (e.g., an on-board data/instruction device), a Ka high-flux satellite, a C-band large-beam satellite, and an earth station host system. The earth station master station system may further include a Ka high-throughput satellite gateway station, a C-band satellite master station, and a master station server cluster (for connecting to the internet or a 5G (5 th Generation Mobile Communication Technology, fifth-generation mobile communication technology) communication network). The earth station host system exchanges data with subscribers via a ground private line or VPN (Virtual Private Network ). The user-side devices may further include network switches, consoles, databases, video surveillance, and the like. Wherein, the on-board Ka high-flux satellite communication terminal, the Ka high-flux satellite and the Ka high-flux satellite gateway station form a Ka high-flux satellite communication network; the shipborne C-band large-beam satellite communication terminal, the C-band large-beam satellite and the C-band satellite master station form a C-band large-beam satellite communication network; the data/instruction equipment is used as shipborne service equipment, and the shipborne satellite intelligent sensing and switching gateway equipment is used for selecting a Ka high-flux satellite communication network or a C-band large-beam satellite communication network to realize shipborne service communication.
When the link quality of the Ka satellite communication terminal is normal, the system utilizes the on-board satellite intelligent sensing and switching gateway equipment and the Ka high-flux satellite communication network to realize the on-board high-speed communication; when the on-board satellite intelligent sensing and switching gateway equipment detects that the Ka satellite communication link quality is gradually deteriorated (for example, deterioration caused by factors such as heavy rain) the on-board satellite communication link is automatically switched to the C satellite communication link, namely the system realizes the on-board replacement communication by utilizing the on-board satellite intelligent sensing and switching gateway equipment and the C-band large-beam satellite communication network; when the on-board satellite intelligent sensing and switching gateway equipment detects that the Ka satellite communication terminal link quality is recovered from a deteriorated state to a stable state, the current communication link is automatically switched to the Ka satellite communication terminal link, and high-speed communication is performed by using the Ka high-throughput satellite communication network.
Fig. 2 shows a flowchart of an exemplary satellite communication terminal intelligent handoff method provided according to an embodiment of the present application.
In the communication process, the intelligent switching method of the satellite communication terminal can combine the advantages of high speed of the shipborne Ka high-flux satellite communication terminal and the advantages of high reliability of the shipborne C-band large-beam satellite communication terminal, so that high-speed and reliable communication of the system is guaranteed. The shipborne data/instruction equipment of the shipborne communication system normally realizes the shipborne communication through the shipborne satellite intelligent sensing and switching gateway equipment and the Ka high-flux satellite communication network; when the on-board satellite intelligent sensing and switching gateway equipment detects that the link quality of the Ka satellite communication terminal link is gradually deteriorated due to rain attenuation and the like, the communication link is automatically switched to the C satellite communication terminal link, namely on-board data/instruction equipment realizes the on-board communication through the on-board satellite intelligent sensing and switching gateway equipment and a C frequency band large beam satellite communication network; and when the on-board satellite intelligent sensing and switching gateway equipment detects that the quality of the Ka Weitong terminal link is recovered stably, automatically switching the communication link back to the Ka Weitong terminal link. The specific flow is as follows:
Step S201: initializing a shipborne satellite communication system, wherein the shipborne satellite communication system is connected to a Ka high-flux satellite communication network and a C-band large-beam satellite communication network; ktC =0; ktka=0.
Before starting communication service transmission, the satellite communication terminal needs to be initialized to access the network. The method comprises the steps of starting shipborne data/instruction equipment, shipborne satellite intelligent sensing and switching gateway equipment, shipborne Ka high-flux satellite communication terminals and shipborne C-band large-beam satellite communication terminals, enabling the shipborne data/instruction equipment to communicate with a shore base through the Ka high-flux satellite communication network and the C-band large-beam satellite communication network by automatically connecting the Ka high-flux satellite communication terminals and the C-band large-beam satellite communication network to the satellites respectively, initializing Ka high-flux satellite service channel transmission marks ktKa to 0 (ktKa=0), and initializing C-band large-beam satellite service channel transmission marks ktC to 0 (ktC =0).
Step S202: and confirming whether the Ka guard terminal link is selected to initiate the high-speed service communication request.
And after network access initialization is completed, selecting an initial satellite communication terminal according to the service communication rate requirement. Because the on-board Ka high-throughput satellite communication terminal has the characteristic of high communication rate, in general cases (for example, the requirement for the communication rate is greater than or equal to 2 Mbps), when in initial operation, a Ka satellite communication terminal link is selected by default to ensure the on-board communication, that is, a Ka high-throughput satellite communication network where the on-board Ka high-throughput satellite communication terminal (for example, the first terminal, the terminals including Ka in the following may be the first terminal) is selected to perform the on-board high-speed communication, and then step S203 is performed. And only when the ship-borne C-band large-beam satellite communication terminal is in severe environmental conditions such as heavy rain and the like during initial operation, selecting a C-band large-beam satellite communication network where a ship-borne C-band large-beam satellite communication terminal (for example, a second terminal, and the terminal containing C in the following description can be the second terminal) is positioned to perform ship-shore broadband communication, and then proceeding to step S212.
Step S203: the high-speed communication on the ship shore is performed by using a Ka high-flux satellite communication network, and SUM=0, SUMB=0 and Ktka=1 are initialized. If KtC =1, wait for 1S, stop transmitting traffic through the C-beam satellite communication network, and let KtC =0. The current time t0 is recorded.
After a Ka satellite communication terminal link is initially selected to carry out the shore high-speed communication (namely, a Ka high-flux satellite communication network is utilized to transmit the shore service), or when the shore communication link is automatically switched to the Ka satellite communication terminal link from a C satellite communication terminal link, assigning a variable SUM=0 of continuous reduction times of the Ka link quality, assigning a variable SUMB=0 of stable times of the Ka satellite communication terminal link quality, and assigning ktKa=1 (which means that the Ka high-flux satellite communication network is utilized to transmit the shore communication service); and meanwhile, the Ka satellite communication terminal link is utilized to realize the shore communication. If KtC =1 (representing that the C-band large beam satellite communication network transmits the ship-shore communication service), the ship-borne satellite intelligent sensing and switching gateway device is utilized to stop the ship-borne C-band large beam satellite communication terminal from transmitting the ship-shore communication service after 1 second, and KtC =0 (representing that the C-band large beam satellite communication network stops transmitting the ship-shore communication service) is assigned. Here, the 1 second time (for example, the second time) is a time when the Ka high-flux satellite communication network and the C-band large-beam satellite communication network simultaneously transmit the service, so as to prevent data loss during the process of switching the C-band large-beam satellite communication network to the Ka high-flux satellite communication network. Next, the current time t0 is recorded.
Step S204: it is determined whether the current time instant has reached a periodic sampling time instant (t 0, t0+dt, t0+2×dt, …, t0+n×dt, …).
If the current time arrives at the first type of periodic sampling time, the first type of periodic sampling time may be a first sampling time (e.g., t0, t0+dt, t0+2×dt, …, t0+n×dt, …; where N is the number of times, and dt is the sampling interval), then step S205 is entered. If the current time does not reach the periodic time, continuing to judge.
Step S205: and reading the SNRC, the symbol rate, the modulation mode and the coding efficiency parameters of the received signal of the Ka terminal service channel at the current moment, and calculating the current communication rate VC. If the time interval of the current time from t0 is an integer multiple of 30×dt (t 0, t0+30×dt, t0+60×dt, …, t0+30×m×dt, …), a latency detection ping packet is sent by the Ka high throughput satellite communication terminal (ping (Packet Internet Groper) packet is an internet packet explorer for testing network connection).
Reading parameters of a service channel of a Ka high-throughput satellite communication terminal at the current sampling moment: the method comprises the steps of receiving signal-to-noise ratio (SNRC), symbol rate, modulation mode and coding efficiency, calculating a communication rate value VC and storing VC by using a symbol rate value SR, modulation factors MI (such as BPSK, QPSK, 8PSK and 16QAM modulation factors are 1, 1/2, 1/3 and 1/4 respectively) of the modulation mode and a coding efficiency value CE, and analyzing the link quality of the Ka high-flux satellite communication terminal. The calculation of the communication rate value VC is specifically as follows:
VC＝(SR/MI)×CE
If the time interval between the current sampling moments is an integer multiple of 30×dt, that is, the periodic sending moments (for example, t0, t0+30×dt, t0+60×dt, …, t0+30×m×dt, …; where M is the number of times and 30×dt is the sending interval), the on-board satellite intelligent sensing and switching gateway device sends a delay detection ping packet (for example, a first data packet) to the Ka high-flux satellite gateway station through the traffic channel of the Ka high-flux satellite communication terminal, so as to detect the round trip delay when the Ka high-flux satellite network is used for normal communication between the ship and the shore, and further detect the traffic channel of the Ka high-flux satellite communication terminal.
Step S206: sum=sum+1 if SNRC < SNRP-C and VC/VP < K. If VC/VP is greater than or equal to K, SUM=0. And if the round trip delay ping C of the delay detection ping packet is received and the sum of the delay detection ping packet and the delay detection ping packet is |ping C-ping P| < d, updating the weighted average value ping T=alpha×ping T+beta×ping C of the delay detection ping packet, assigning ping P=ping C, otherwise, not updating the ping T and the ping P.
The received signal-to-noise ratio (SNRC) of the high throughput satellite communication terminal at the current sampling instant Ka and the received signal-to-noise ratio (SNRP) at the last sampling instant are compared with a difference value of a threshold C (e.g., a first threshold), wherein the threshold C may be 2. The ratio of the communication rate (VC) of the traffic channel of the high-throughput satellite communication terminal at the calculated current sampling instant Ka and the communication rate (VP) calculated at the last sampling instant is compared with a threshold K (e.g., a second threshold), wherein the threshold K may be 70%. If SNRC < SNRP-C and VC/VP < K (indicating that after the received signal-to-noise ratio is reduced, the high throughput satellite communication network has automatically reduced the communication rate according to its adaptive code modulation strategy, and at this time, the quality of the Ka-satellite terminal link is deteriorated), the variable sum=sum+1 of continuous reduction times of the quality of the Ka-link is updated, and the updated SUM is used as an analysis result of the quality of the Ka-link. If VC/VP is greater than or equal to K, SUM=0 is assigned.
And detecting whether response information of the delay detection ping packet is received at the moment, and if the response information is received, recording the round trip delay ping C of the delay detection ping packet. It can be understood that after the on-board satellite intelligent sensing and switching gateway device sends a ping packet to the Ka high-flux satellite gateway station through the service channel of the Ka high-flux satellite communication terminal, if the Ka high-flux satellite gateway station receives the ping packet, the on-board satellite intelligent sensing and switching gateway device returns response information of the ping packet to the on-board satellite intelligent sensing and switching gateway device; the round trip delay of the ping packet is from the moment that the on-board satellite intelligently perceives and switches the ping packet to the moment that the on-board satellite receives the response information of the ping packet. If the on-board satellite intelligent sensing and switching gateway device receives the response information ping c and satisfies |ping c-ping p| < d (the threshold d can be a third threshold and can be 20% of the weighted average value ping t of the delay of the detected ping packet, and ping p is the round trip delay of the last delay detected ping packet), updating the weighted average value ping t=α×ping t+β×ping c of the delay detected ping packet (the first calculated value of ping t is equal to the round trip delay ping c of the first delay detected ping packet, i.e. ping t=ping c, α, β is a weight value, and storing the weighted average value), and assigning value ping=ping c; otherwise, ping t and ping p are not updated. And taking the updated weighted average value as a detection result of the service channel of the Ka high-flux satellite communication terminal.
Step S207: SUM <3 is judged.
If SUM is 3 or more, step S208 is entered. If SUM <3, return to step S204. It will be appreciated that the value 3 (e.g., fourth threshold) is merely an exemplary preset threshold, and may be adjusted in practice according to experience of those skilled in the relevant art.
Step S208: and sending a deterioration detection ping packet through the Ka high-flux satellite communication terminal, and recording the current packet sending time value Tfa.
If SUM is more than or equal to 3 (for example, a fourth threshold value), the condition that the continuous reduction frequency of Ka link quality reaches the set maximum frequency is indicated, and at the moment, the on-board satellite intelligent sensing and switching gateway equipment is required to send a deterioration detection ping packet (for example, a second data packet) through the Ka high-throughput satellite communication terminal for detecting the deterioration of the link quality, and comprehensively judging whether the Ka satellite communication terminal link has deteriorated according to the response condition of the data packet and the continuous reduction condition of the receiving signal-to-noise ratio and the communication rate of the service channel. After the transmission of the degradation detection ping packet, the time at which the degradation detection ping packet is transmitted is recorded as the degradation detection ping packet transmission time Tfa (for example, the second packet transmission time).
Step S209: and judging the current time value < Tfa+pingT+G.
If the current time value < tfa+pingt+g (the threshold G may be the fifth threshold and may be set to 0.8×pingt, which may be adjusted according to the experience of those skilled in the art in practice), step S210 is entered. If the current time value is equal to or greater than Tfa+ping T+G, the fact that the response information of the degradation detection ping packet is not received in the time period of the ping T+G after the degradation detection ping packet is sent is indicated, the comprehensive judgment is performed that the link quality of the Ka guard terminal is degraded, and the step S212 is entered.
Step S210: and inquiring whether response information of the degradation detection ping packet is received or not.
After the transmission of the ping packet for degradation detection, it is necessary to inquire whether response information of the degradation detection ping packet is received. Step S211 is entered under the condition that the current time value < tfa+ping t+g is satisfied and the response information of the deterioration detection ping packet can be received. If the current time value < tfa+ping t+g is satisfied but no response information for the degradation detection ping packet is received, the flow returns to step S209.
Step S211: assign sum=0.
If the current time value is < Tfa+ping T+G, and the response information of the ping packet detected by deterioration can be received, the link quality of the Ka guard terminal is not excessively reduced. At this time, sum=0 is assigned to make statistics again on the Ka link quality continuous degradation number variable. Then, the process returns to step S204.
The following describes a procedure for switching to or selecting a C-band large beam satellite communications network to effect shore broadband communications.
Step S212: the C-band large beam satellite communication network is selected to realize the ship-shore broadband communication, and KtC =1. If ktka=1, waiting for 1s, stopping transmitting the service through the Ka high-throughput satellite network; sum=0; ktka=0; sumb=0. The current time t1 is recorded.
The ship-borne satellite intelligent sensing and switching gateway equipment realizes ship-shore broadband communication through a C satellite communication terminal link of a ship-borne C-band large-beam satellite communication terminal, and is assigned with KtC =1 (which means that the C-band large-beam satellite communication network transmits ship-shore communication service). If the on-board satellite communication link is automatically switched from the Ka-satellite communication terminal link to the C-satellite communication terminal link (i.e., ktka=1 at this time), the on-board satellite intelligent sensing and switching gateway device stops transmitting the shore communication service through the Ka-high throughput satellite communication terminal after 1 second (e.g., after the first time), the on-board C-band large beam satellite communication terminal and the Ka-high throughput satellite communication terminal simultaneously transmit the communication service within 1 second, so as to prevent data loss during the switching process of the two terminals, and assigns ktka=0 (which indicates that the Ka-high throughput satellite communication network stops transmitting the shore communication service). Meanwhile, initializing sum=0, initializing a variable sum=0 of the link quality stabilization times of the Ka satellite communication terminal, and recording the current time as t1.
Step S213: it is determined whether the current time arrives at a sampling time (t 1, t1+dt1, t1+2×dt1, …, t1+n×dt1, …) where dt1 is a period.
With dt1 (ms) as a period, if the current time arrives at a third type of period sampling time, which may be a second sampling time (e.g., t1, t1+dt1, t1+2×dt1, …, t1+n×dt1, …), step S214 is entered. If the current time does not reach the third type of period sampling time with dt1 as a period, continuing to judge.
Step S214: the lock star RxLock is read.
The intelligent sensing and switching gateway equipment of the shipborne satellite reads a satellite locking sign RxLock of the Ka high-flux satellite communication terminal and records the RxLock value of the sampling moment.
Step S215: rxlock=1 is judged.
Rxlock=1 indicates that the Ka high-throughput satellite communication terminal has locked a satellite and has established communication connection with the satellite; rxlock=0 indicates that the Ka high throughput satellite communication terminal fails to establish a communication connection with the satellite. If rxlock=1, step S216 is entered. If it is determined that RxLock is not equal to 1, that is, rxlock=0, step S213 is returned.
Step S216: the received signal-to-noise ratio SNR1C is read. If |snr1C-SNR1p| < K, sumb=sumb+1, otherwise sumb=0.
And reading and storing a received signal-to-noise ratio SNR1C of a Ka high-flux satellite communication terminal channel at the current sampling moment (RxLock=1 is in a locked state at this time, which means that the Ka high-flux satellite communication terminal has received and demodulated a forward carrier wave containing a broadcast signal). If the high-throughput satellite communication terminal at the last sampling time Ka is in a locked star state, and the absolute value of the difference between the received signal-to-noise ratio (SNR 1P) at the last sampling time and the received signal-to-noise ratio SNR1C at the current sampling time is smaller than a threshold K (for example, |snr1C-SNR1p| < K, the threshold K may be a sixth threshold and may be set to 0.8), a sum=sum+1 is assigned; if the lock star flag rxlock=0 at the previous sampling time (for example, the received signal-to-noise ratio read in the 1 st sampling period is SNR1, the rxlock=0 at the 2 nd sampling time, the satellite out-of-lock does not correspond to the received signal-to-noise ratio, and the received signal-to-noise ratio at the 3 rd sampling time is SNR3, when the 3 rd sampling time is judged, the RxLock at the 2 nd sampling time is read, and the rxlock=0 at the moment is found, the second sampling time fails to lock the star, and does not correspond to the received signal-to-noise ratio, so for the 3 rd sampling time, the rxlock=0 at the previous sampling time, or the absolute value of the difference between the received signal-to-noise ratio at the current sampling time and the received signal-to-noise ratio at the previous sampling time is greater than or equal to a threshold K (|snr 1C-SNR1 p|k), and sumb=0 is assigned. In other words, at two adjacent sampling moments (for example, t1+2×dt1 and t1+3×dt 1), the Ka high-throughput satellite communication terminal is in a locked state, and the received signal-to-noise ratio variation of the two consecutive sampling moments of the Ka high-throughput satellite communication terminal is within the threshold K, then the link quality of the continuous two sampling periods Ka guard through terminal is considered to be stable (so that the value sumb=sumb+1 is assigned at this time).
Step S217: and judging that SUMB is more than or equal to 3.
If the counted number of stable link quality times of the Ka satellite communication terminal is greater than or equal to a preset threshold (for example, a seventh threshold can be set to be 3, namely SUMB is greater than or equal to 3), the condition that the Ka high-flux satellite communication terminal is in a satellite locking state and the receiving signal to noise ratio of the Ka high-flux satellite communication terminal changes stably in adjacent sampling periods is indicated, and the Ka high-flux satellite communication terminal has a communication recovery function. At this time, the flow advances to step S203, where a satellite communication link switching operation is performed. If SUMB is less than 3, returning to the step S213, and continuously periodically counting the stable times of the link quality of the Ka satellite communication terminal.
According to the method, in the first aspect, through dynamic monitoring of parameters such as a receiving signal-to-noise ratio, a communication rate and the like of a service channel of the Ka high-flux satellite communication terminal, active detection of round trip delay of a ship shore of the Ka high-flux satellite communication network is combined, deterioration conditions of link quality of the Ka satellite communication terminal are dynamically analyzed, intelligent monitoring and real-time prejudging of online communication capacity of the Ka high-flux satellite communication terminal are achieved, and an intelligent detection method for link quality of the Ka high-flux satellite communication terminal is formed.
According to the second aspect, based on the Ka high-flux satellite communication terminal link quality intelligent detection method, the Ka high-flux satellite communication terminal and C-band large-beam satellite communication terminal intelligent switching method is formed by combining periodic monitoring and judgment of the Ka high-flux satellite communication terminal satellite locking and receiving signal-to-noise ratio when the Ka satellite communication terminal link quality is continuously deteriorated. By utilizing the method, when the quality of the Ka satellite communication link is deteriorated, the shipborne satellite communication link can be automatically switched to the C satellite communication link; when the quality of the Ka satellite communication link is recovered from a deteriorated state to a stable state, the on-board satellite communication link can be automatically switched from the C satellite communication link to the Ka satellite communication link, and the satellite communication link is ensured to work reliably and at high speed.
In the third aspect, by combining the advantage of high speed of Ka high-flux satellite communication and the advantage of high reliability of C-band large-beam satellite communication, an offshore high-speed and reliable satellite communication scheme is provided by utilizing the intelligent switching method of the Ka high-flux satellite communication terminal and the C-band large-beam satellite communication terminal, and high-speed and reliable communication of luxury cruise ships, intelligent ships and the like in the middle and open sea is ensured.
