[0002] In a satellite communication system, any satellite moves along a preset movement trajectory. During the movement of the satellite, it is necessary to switch from one satellite gateway station to another satellite gateway station (for the sake of description, "one satellite gateway station" is referred to as the original satellite gateway station, and "another satellite gateway station" is referred to as the target satellite gateway station). In a satellite communication system, a user bearer is established between the satellite gateway station and the core network. Among them, the original satellite gateway station and the target satellite gateway station may belong to the same core network or different core networks, that is, in the case where the original satellite gateway station and the target satellite gateway station belong to the same core network, the original core network and the target core network are the same.

[0003] Currently, when a satellite switches from the original satellite gateway station to the target satellite gateway station, the services of the target terminal (the terminal within the coverage area of the satellite on the ground at the switching moment) need to be interrupted. In the scenario of feeder link switching, how to ensure that data is not lost or lost as little as possible and minimize the impact of feeder switching on service performance is an issue that must be considered during the data transmission process.

[0037] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation of the present disclosure.

[0038] In the technical solution of the present disclosure, the acquisition, storage, use, processing, etc. of data all comply with the relevant regulations of relevant laws and regulations.

[0039] Figure 1It is a schematic diagram of a data processing method according to an embodiment of the present disclosure, which is executed by an access network device. For example, Figure 1 As shown, the data processing method includes the following steps:

[0040] S101, polling the power supply status of the satellite.

[0041] Regardless of the dual-satellite single-station scenario or the single-satellite cross-station scenario, the switching of the power supply link requires the cooperation of multiple network elements such as satellites, gateway stations, and access network devices to ensure the reliability of data transmission, reduce the service interruption time and handover delay caused by the switching of the power supply link, and ensure the continuity of the service.

[0042] For example, Figure 2 As shown, the satellite monitored in the embodiment of the present disclosure can be any satellite in the satellite constellation, and there can be multiple gateway stations or one gateway station, which can be determined according to the actual situation. Figure 2 Only one gateway station in [[ ]] is shown, which is only used to show the communication connection relationship among the satellite, gateway station, terminal, access network device, and control device.

[0043] The method of the present disclosure is used to introduce the interaction process among devices in the satellite communication system when the power supply link between the satellite and the gateway station changes. The data processing method of the embodiment of the present disclosure is executed with the access network device as the main body.

[0044] In the embodiment of the present disclosure, for example, Figure 2 As shown, the power supply link is divided into a forward link and a reverse link. In the forward link, the gateway station receives the IP packet from the access network device, extracts the payload, and sends it to the power supply link for transmission; after the satellite directly connected to the gateway station (power supply direct satellite) receives the data sent by the gateway station, it looks up the routing table according to the destination satellite address carried in the packet, and sends the data to the destination satellite communicating with the user terminal. The destination satellite sends the data to the terminal through the user link. In the reverse link, after the satellite receives the data from the terminal, it sends the data to the satellite directly communicating with the gateway station according to the routing table; the power supply direct satellite sends the data to the gateway station according to the power supply link interface, and the gateway station forwards the packet to the access network device on the ground.

[0045] In the embodiment of the present disclosure, the power supply status of the satellite can be monitored by adding a satellite power supply working status polling function to the access network device.

[0046] S102, determining the power supply link status between the gateway station and the satellite based on the power supply status of the satellite.

[0047] In the embodiment of the present disclosure, the power supply status of the satellites in the satellite constellation can be obtained by polling the satellites through the satellite power supply working status polling function, and the status of the power supply link between the satellite and the gateway station can be determined based on the conversion of the power supply status.

[0048] It should be noted that, as Figure 3 shown, the power feeding states of the satellite may include multiple types. For example, they may include working, invalid, and switching, etc. Among them, the working state indicates that the satellite is working normally, the invalid state indicates that the route is unreachable, and the switching state indicates that a handover is in progress.

[0049] S103, process the transmitted data based on the power feeding link state.

[0050] In the embodiments of the present disclosure, the data processing operations corresponding to different power feeding link states may be different, so as to dynamically adjust data transmission according to the power feeding link state between the satellite and the gateway station.

[0051] It should be noted that the data processing operation is designed in advance and can be changed according to actual design needs, and no specific limitations are made here. For example, when transmitting data through the forward link, when the power feeding link state is switching, the data connection between the satellite and the gateway station can be paused first, and after the power feeding link state between the satellite and the power feeding link becomes normal, the data transmission can be continued.

[0052] In the embodiments of the present disclosure, first poll the power feeding state of the satellite, then determine the power feeding link state between the gateway station and the satellite based on the power feeding state of the satellite, and finally process the transmitted data based on the power feeding link state. Thus, by polling the power feeding state of the satellite to determine the power feeding link state between the gateway station and the satellite, different data transmission schemes can be determined according to different power feeding link states, realizing dynamic adjustment of the data transmission between the satellite and the gateway station, and improving the effect of data transmission and the user experience.

[0053] In the above embodiments, processing the transmitted data based on the power feeding link state can also be achieved through Figure 4 further explanation, Figure 4 is a schematic diagram of another data processing method of an embodiment of the present disclosure. The method includes:

[0054] S401, in response to the state of the power feeding link being the switching state and the access network device having forward data to be sent, perform a blocking operation on the forward data transmission of the access network device.

[0055] In implementation, since the gateway station in satellite communication may have a large number of connected cells and a large number of users, when the state of the power feeding link is the switching state, it can be considered that the transmission between the gateway station and the satellite is temporarily unavailable, which will cause a large amount of forward data to accumulate at the gateway station, resulting in a large data processing pressure on the gateway station. At the same time, it will reduce the impact of power feeding handover on service performance and affect the normal communication of users.

[0056] In an embodiment of the present disclosure, after determining that the state of the feeder link is a handover state, in order to prevent all forward data from being backlogged at the gateway station, the present disclosure proposes to perform a blocking operation on the forward data transmission to the access network device.

[0057] It should be noted that this blocking operation is to delay the forward data transmission at the access network device.

[0058] S402, when the recovery condition is met, stop the blocking operation and resume the forward data transmission of the access network device.

[0059] In an embodiment of the present disclosure, the recovery condition can be various and is not limited here. For example, the recovery condition can be after the blocking operation reaches a preset time, or it can also be after the state of the feeder link changes back to the normal working state.

[0060] It should be noted that after recovery, the gateway station connected to the access network device can be the original gateway station or other gateway stations changed due to the handover, which is not limited here and specifically needs to be determined according to the actual handover scenario.

[0061] In an embodiment of the present disclosure, in response to the state of the feeder link being a handover state and there being forward data to be sent at the access network device, a blocking operation is performed on the forward data transmission of the access network device, and finally, when the recovery condition is met, the blocking operation is stopped and the forward data transmission of the access network device is resumed. Thus, when the state of the feeder link between the satellite and the gateway station is a handover state, by performing a blocking operation on the forward data transmission of the access network device, the forward data can be stopped at the access network device, preventing a large amount of forward data from accumulating at the gateway station, reducing the data processing pressure of the gateway station, and improving the satellite communication effect and the user experience.

[0062] It should be noted that when the reverse link is transmitting, it is mainly necessary to ensure that the access network can connect to all gateway stations and has the functions of reordering and concatenation, so as to ensure the reliable service transmission of the reverse link.

[0063] It should be noted that considering the limited processing capacity of the satellite, the satellite uses transparent forwarding; the access network device separates the Centralized Unit (CU) and the Distributed Unit (DU) and is deployed on the ground.

[0064] In an embodiment of the present disclosure, the blocking operation on the forward data transmission of the access network device can also be achieved through Figure 5 For further explanation, Figure 5 is a schematic diagram of another data processing method of an embodiment of the present disclosure. This method includes:

[0065] S501. Obtain the broadcast indication of the power feeding interface process of the access network device.

[0066] In the embodiments of the present disclosure, the function of periodically broadcasting the power feeding working state of the satellite can be added to the access network device. By polling the state of the power feeding link of the satellite to which the terminal belongs, a broadcast indication is generated based on the power feeding working states of all satellites.

[0067] S502. Determine the target satellite that needs to perform power feeding link switching based on the broadcast indication. The target MAC process corresponding to the target satellite performs a blocking operation on the forward data transmission, where the target MAC process is all MAC processes that the access network device will send to the target satellite through the power feeding link.

[0068] It should be noted that the target satellite for power feeding link switching may include multiple beams, and each beam corresponds to a MAC process in the access network device. When performing power feeding link switching on the target satellite, by performing a blocking operation on the forward data to be sent through the target MAC process, the blocking moment sent by the control device can be obtained first. At the blocking moment, the target MAC process performs a blocking operation on the forward data transmission.

[0069] In the embodiments of the present disclosure, the control device may be a measurement, operation, and control system. The measurement, operation, and control system is a system for measuring and controlling satellites, gateway stations, terminals, etc.

[0070] It should be noted that the blocking moment may be the switching moment of the power feeding link of the target satellite. However, due to a certain degree of delay in transmission, the blocking moment can also be determined based on the delay on the basis of the switching moment. Specifically, it can be set according to actual design requirements.

[0071] It should be noted that the switching moment and the blocking moment corresponding to different scenario categories may be different, and no specific limitation is made here. Specifically, it can be limited according to actual design requirements and switching requirements.

[0072] In the embodiments of the present disclosure, the blocking time length can be set, and the blocking time length of the blocking operation is controlled by a timer. The blocking time length is generated by the control device. After the blocking operation reaches the blocking time length, it can be considered that the recovery condition is met at this time. The access network device sends the data to the gateway station, and the gateway station sends it to the corresponding satellite.

[0073] In the above embodiments, the control device generates the blocking time length, which can be through Figure 6 For further explanation, Figure 6 is a schematic diagram of another data processing method according to an embodiment of the present disclosure. The method includes:

[0074] S601. Determine the current scenario category.

[0075] In an embodiment of the present disclosure, the current timestamp routing information and the next timestamp routing information may be obtained first, where the current timestamp routing information and the next timestamp routing information are generated by a control device, and then the current scene category is determined based on the current timestamp routing information and the next timestamp routing information.

[0076] In a possible implementation manner, in response to a change in the feeder-through satellite ID in the current timestamp routing information and the feeder-through satellite ID in the next timestamp routing information, and the gateway station ID in the current timestamp routing information remaining unchanged from the gateway station ID in the next timestamp routing information, the scene category is determined to be dual-satellite cross single gateway station; in response to the feeder-through satellite ID in the current timestamp routing information remaining unchanged from the feeder-through satellite ID in the next timestamp routing information, and a change in the gateway station ID in the current timestamp routing information and the gateway station ID in the next timestamp routing information, the scene category is determined to be single-satellite cross dual gateway stations.

[0077] It should be noted that a feeder-through satellite refers to a satellite that communicates directly with a gateway station, and the feeder-through satellite IDs corresponding to each feeder-through satellite are different.

[0078] S602, the control device generates a blocking time length based on the scene category.

[0079] It should be noted that the generation algorithms for the blocking time lengths corresponding to different scenes may be different, and may be specifically set according to actual design requirements.

[0080] For the dual-satellite cross single gateway station scene, according to the feeder routing table information, at the timestamp before the original satellite is about to move away from the gateway station, the original satellite, as the satellite directly communicating with the gateway station, has been undertaking the task of data landing; after the original satellite moves away from the gateway station, the satellite directly communicating with the gateway station changes, and the feeder link switches to the link between the target satellite and the gateway station. Due to the problem of transmission delay, after the feeder link switches, the gateway station still needs to continue receiving the data of the original satellite for a period of time and send the data to the access network device.

[0081] It should be noted that the feeder routing table is distributed by the control device, and provides information such as the link establishment time, link disconnection time, inter-satellite feeder routing, and time slice information between the satellite and each gateway station. For a certain time slice and target address, the feeder routing provides multiple path information, including path priorities. The time slice length of the feeder routing table is a fixed length; the feeder link switch occurs at the whole minute boundary and will not switch within the time slice. The access network device determines the ground mission plan according to the feeder routing table.

[0082] In another possible implementation manner of the present disclosure, when the gateway station sends data to the access network device, since the gateway station may have been switched, the data received by the access network device may be the data sent by two gateway stations. To solve this problem, the transmitted data is processed based on the status of the feeder link, and it can also be solved by the method as shown in Figure 7 shown below. Figure 7 FIG. Figure 7 is a schematic diagram of another data processing method according to an embodiment of the present disclosure, as shown in Figure 7 below:

[0083] S701, in response to the status of the feeder link being the switching state, when receiving the reverse data sent by the receiving gateway station through the reverse link of the feeder link, determine the current scene category.

[0084] Determining the current scene category can refer to the content in the above embodiments, which will not be elaborated here.

[0085] S702, perform data processing on the reverse data based on the scene category.

[0086] It should be noted that the data processing methods for the reverse data corresponding to different scene categories may be different, which are not limited here, and specifically need to be set according to actual design requirements.

[0087] In the embodiments of the present disclosure, in response to the scene category being single satellite crossing two gateway stations, perform reordering and concatenation processing on the first reverse data of the first gateway station and the second reverse data of the second gateway station received. Herein, the first gateway station is the gateway station before switching, and the second gateway station is the gateway station after switching.

[0088] It should be noted that in the case of the scene category being single satellite crossing two gateway stations, due to the problem of transmission delay, and after the feeder link is switched, the satellite transmission channel needs to be delayed for a period of time to switch, the original gateway station still needs to continue to receive satellite data for a period of time after the feeder link is switched and send the data to the access network device; at the same time, the satellite data after switching is also sent to the target gateway station and sent to the access network device by the target gateway station. The access network device needs to receive the reverse data forwarded by two gateway stations simultaneously, and for the data belonging to the same terminal, the access network device needs to perform reordering and concatenation processing.

[0089] In response to the scene category being double satellites crossing a single gateway station, perform data processing on the third reverse data sent by the third gateway station.

[0090] For the scenario of two satellites crossing a single gateway station, according to the feeder route table information, at the timestamp before the original satellite is about to move away from the gateway station, the original satellite, as the satellite directly communicating with the gateway station, has been undertaking the task of data landing; after the original satellite moves away from the gateway station, the satellite directly communicating with the gateway station changes, and the feeder link switches to the link between the target satellite and the gateway station. Due to the problem of transmission delay, after the feeder link switches, the gateway station still needs to continue receiving the data of the original satellite for a period of time and send the data to the access network device.

[0091] In the above embodiment, the state of the feeder link between the monitoring satellite and the gateway station can also be obtained through Figure 8 For further explanation, Figure 8 is a schematic diagram of another data processing method according to an embodiment of the present disclosure. The method includes:

[0092] S801, for any terminal-attributing satellite, based on the route table, determine the first link state of the feeder link of the terminal-attributing satellite at the current timestamp, and determine the second link state of the feeder link of the terminal-attributing satellite at the next timestamp.

[0093] In the embodiment of the present disclosure, the satellite feeder working state polling function can be added to the access network device, and by polling the feeder link of the terminal-attributing satellite, the link state of the polling feeder link can be realized.

[0094] In the embodiment of the present disclosure, in the code implementation of the feeder interface process, the routing information of "a certain timestamp" is represented by the global variable routeTab_g[t][d]; where t indicates the timestamp index and d indicates the target ID index. The writing and reading of the route table are based on the indexes t and d. By parsing the routing information, the first link state of the feeder link of the terminal-attributing satellite at the current timestamp and the second link state at the next timestamp can be determined.

[0095] S802, determine the state of the feeder link based on the first link state and the second link state.

[0096] In the embodiment of the present disclosure, the state of the feeder link can be determined by the state of the feeder link at the current timestamp and the state of the feeder link at the next timestamp. For example, it may include the following multiple scenarios:

[0097] Scenario 0: Working -> Working; indicating that the first link state of the terminal-attributing satellite is normal working at the current timestamp, and the second link state is also normal working at the next timestamp, and there is no feeder link switch;

[0098] Scenario 1: Working -> Invalid; indicating that the first link state of the terminal-attributing satellite is normal working at the current timestamp, and the second link state is that the route will be unreachable at the next timestamp;

[0099] Scenario 2: Working -> Switching; It indicates that the satellite to which the terminal belongs has a normal working status for the first link at the current timestamp, and a normal working status for the second link at the next timestamp. However, there is a switch at the start boundary of the next timestamp for the feed-through satellite.

[0100] Scenario 3: Invalid -> Working; It indicates that the satellite to which the terminal belongs has an unreachable routing status for the first link at the current timestamp, and a normal working status for the second link at the next timestamp.

[0101] Scenario 4: Invalid -> Invalid; It indicates that the satellite to which the terminal belongs has an unreachable routing status for the first link at the current timestamp, and an unreachable routing status for the second link at the next timestamp.

[0102] Scenario 5: Invalid -> Switching; It indicates that the satellite to which the terminal belongs has an unreachable routing status for the first link at the current timestamp, and a reachable routing status for the second link at the next timestamp. However, there is a switch at the start boundary of the next timestamp for the feed-through satellite.

[0103] Scenario 6: Switching -> Working; It indicates that the satellite to which the terminal belongs has a normal working status for the first link at the next timestamp, and a normal working status for the second link at the current timestamp. However, there is a switch at the start boundary of the current timestamp for the feed-through satellite.

[0104] Scenario 7: Switching -> Invalid; It indicates that there is a switch at the start boundary of the first link of the feed link at the current timestamp, and an unreachable routing status for the satellite to which the terminal belongs at the second link at the next timestamp.
