[0084] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments of the present application, the terms used in the following embodiments are only for the purpose of describing the specific embodiments and are not intended to be limiting on the present application. As used in the specification and the appended claims of the present application, the singular forms “a,” “an,” and “the” are intended to include the plural forms, e.g., “one or more,” unless the context clearly indicates otherwise. It will also be understood that “at least one” and “one or more” refer to one or two or more (including two) in the following embodiments of the present application.

[0085] In the present specification, the phrase “one embodiment” or “some embodiments” etc. means that a particular feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, the phrases “in one embodiment,” “in some embodiments,” “in other some embodiments,” “in yet some embodiments,” etc. appearing in various places in the specification are not necessarily all referring to the same embodiment, but mean “one or more but not all embodiments” unless otherwise specifically stated. The terms “comprising,” “including,” “having” and their conjugates mean “including but not limited to,” unless otherwise specifically stated. The term “connected” includes both direct and indirect connections unless otherwise specifically stated. “First,” “second,” etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features.

[0086] In the embodiments of the present application, the words “exemplary” or “for example” are used to mean serving as an example, instance, or illustration. Any embodiment or design presented as “exemplary” or “for example” in the embodiments of the present application is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the words “exemplary” or “for example” is intended to present concepts in a concrete manner.

[0087] In some embodiments, the satellite network is one of a non-terrestrial network (NTN), and the satellite network can refer to a network that deploys a base station or part of the base station function on a satellite system to provide communication for terminal devices. Optionally, the satellite system includes, for example, a low earth orbit satellite system, a Beidou satellite system, a Tianhong satellite system, a high earth orbit satellite system, a medium earth orbit satellite system, etc.

[0088] In some embodiments, in the case that the communication quality of the ground network is poor, the terminal device can select to switch to establish a communication connection with a low earth orbit satellite.

[0089] Exemplarily, as shown in FIG. 1, a terminal device is connected to a 5G core network integrating a low-orbit satellite network and a ground network. Wherein, the terminal device can acquire a low-orbit satellite within the coverage of a ground station in a case where it is determined that the communication quality of the ground network is poor. In this way, the terminal device can switch to be connected to the low-orbit satellite, so as to perform a corresponding data communication service based on the low-orbit satellite network. Alternatively, when the communication quality of the ground network is good, the terminal device can also select to access the ground communication network to perform a corresponding data communication service.

[0090] As can be seen, although the terminal device can currently perform switching between the ground network and the satellite network. However, in the switching process, the selected satellite system has no necessary connection with the service to be currently performed, but only an arbitrary selection of a satellite system within the coverage. Then, the satellite system after switching may also be unable to provide good communication conditions for the terminal device to perform the service.

[0124] For example, the above only takes a mobile phone as an example to illustrate the structure of the terminal device 100 in the embodiments of the present application, but does not constitute a limitation on the structure and form of the terminal device 100.

[0125] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the terminal device 100.

[0126] The technical solutions involved in the following embodiments can be implemented in a device with the structure shown in FIG. 3 and a system with the architecture shown in FIG. 2.

[0127] The satellite communication method provided by the embodiments of the present application is described in detail as follows.

[0128] FIG. 4 is a flowchart of a satellite communication method provided by an embodiment of the present application. It should be noted that the method is not limited to the specific order shown in FIG. 4 and described below, and it should be understood that in other embodiments, the order of some steps of the method can be exchanged according to actual needs, or some steps of the method can be omitted or deleted. The method includes the following steps:

[0129] S401, the terminal device acquires satellite system information.

[0130] Optionally, the satellite system information includes, for example, information of currently available satellite systems, or the satellite system information includes information of satellite systems selected by a user. Optionally, the information includes, for example, coverage of satellite signals, satellite signal quality information, satellite connectable duration, services supported by satellite signals, satellite uplink and downlink service support bandwidth, and the like. Optionally, the satellite signal quality information includes, for example, time delay, jitter, and the like that may be generated in communication.

[0131] In some embodiments, the terminal device acquires information of currently available satellite systems according to current time, location, motion mode, travel mode, indoor and outdoor state, degree of obstruction, terminal hardware configuration, communication package, and the like.

[0132] For example, the terminal device can acquire information of satellite systems whose signal coverage range the terminal device currently locates in and whose signal quality is qualified. Optionally, the terminal device determines these satellite systems as available satellite systems.

[0133] In some embodiments, the terminal device acquires a satellite system selected by a user and acquires information of the satellite system selected by the user according to user operation.

[0134] For example, the terminal device acquires information of currently available satellite systems and displays the available satellite systems. The terminal device acquires a satellite system selected by a user in the available satellite systems and information of the satellite system according to user operation.

[0135] In some embodiments, the terminal device can trigger acquisition of satellite system information in a case where a cellular network and a wireless network are unavailable. In this way, the terminal device can implement service execution through satellite communication, and avoid service execution abnormity caused by no available network.

[0136] In some embodiments, the satellite system information acquired by the terminal device can include, for example, real-time acquired satellite system information, or satellite system information pre-stored in the terminal device. Optionally, the pre-stored satellite system information in the terminal device can improve the efficiency of the terminal device accessing the satellite system.

[0137] For example, the terminal device can be pre-stored with satellite system information such as frequency points of the satellite system, access channel information, access parameters, satellite ephemeris prediction parameters, and the like. Subsequently, the terminal device can acquire real-time satellite system information of the currently available satellite system according to the current time, location, motion mode, travel mode, indoor or outdoor state, degree of obstruction, terminal hardware configuration, communication package, and the like, in combination with the pre-stored satellite system information. For example, the pre-stored access parameters include a satellite system communication range. Subsequently, in response to a user indicating an operation of operating a service, the terminal device searches for a communication frequency of the current satellite system within the pre-stored satellite system communication range, thereby improving the search efficiency.

[0138] S402, the terminal device acquires service information.

[0139] For example, the service information includes information such as a service type, a service gear, a service name (such as an application name), a service requirement, and the like.

[0140] For example, the service type includes a long video service, a short video service, a live broadcast service, a message service, a music service, a browsing service, a shopping service, a navigation service, a game service, a call service, a short message service, a file download service, and the like.

[0141] For example, the service gear includes a high gear, a medium gear, a low gear, and the like. Alternatively, the service gear can be divided in other manners, such as the service gear including a high gear and a low gear, or the service gear including a first gear, a second gear, a third gear, and a fourth gear. In some examples, the terminal device can divide the service gear according to a service requirement. For example, the service requirement includes a requirement for a communication data volume, a requirement for a communication service time length, a requirement for a communication bandwidth, a requirement for a communication time delay, a requirement for a communication jitter, and the like.

[0142] In some embodiments, the terminal device can acquire service information of all services supported by the terminal device. In other embodiments, the terminal device acquires information of a service selected by a user according to a user operation. For example, the terminal device acquires service information of an application according to a user operation of starting the application.

[0143] For example, as shown in FIG. 5, the terminal device acquires satellite system information and service information through an acquisition module 501.

[0144] It should be understood that the embodiments of the present application do not limit the execution order of step S401 and step S402. For example, the terminal device can execute step S401 first and then execute step S402; or the terminal device can execute step S402 first and then execute step S401.

[0145] S403, the terminal device establishes a first communication service connection with the first target satellite system according to the satellite system information and the service information, so as to execute the first target service through the first communication service connection.

[0146] In some embodiments, after obtaining the satellite system information and the service information, the terminal device can match the satellite system information and the service information to obtain a suitable first target satellite system and / or a first target service.

[0147] For example, the terminal device obtains the first target service corresponding to the available satellite system and the first target satellite system corresponding to the supported service according to the obtained information of the currently available satellite system and the information of all services supported by the terminal device. In this way, the terminal device can select a corresponding satellite system when executing a service subsequently.

[0148] For another example, the terminal device obtains the information of the currently available satellite system. Subsequently, the terminal device detects the operation of the user and obtains the service selected by the user to execute. Then, the terminal device can match the first target satellite system matched with the service selected by the user to execute according to the information of the currently available satellite system. In this way, the terminal device can execute the required service for the user through a suitable satellite system, thereby improving the service execution quality.

[0149] For another example, the terminal device detects the operation of the user selecting a satellite system and can obtain the information of the satellite system. Then, the terminal device can match the first target service matched with the satellite system selected by the user among the services supported by the terminal device according to the information of the services supported by the terminal device. In this way, the terminal device can help the user to determine the currently executable service, thereby obtaining better service execution quality.

[0150] In some embodiments, the terminal device matches the satellite system information and the service information according to a preset method to obtain the first target satellite system and / or the first target service. Optionally, the preset method includes, for example, an ordering matching method, a grid matching method, an Euclidean distance calculation matching method, an optimal matching method, and the like.

[0151] In some embodiments, the terminal device can obtain multiple satellite systems matching the service information. Then, the terminal device can sort the multiple satellite systems, and determine the satellite system ranked first as the first target satellite system. In this way, the terminal device can provide the satellite system most suitable for performing the current service for the user. Alternatively, the terminal device can also determine the satellite system selected by the user from the multiple satellite systems as the first target satellite system according to the user operation. In this way, the terminal device can not only provide the satellite communication service for the user, but also meet the personalized needs of the user.

[0152] In some embodiments, the terminal device can obtain multiple services matching the satellite system information. Then, the terminal device can sort the multiple services, and determine the service ranked first as the first target service. In this way, the terminal device can provide the service most suitable for performing for the user. Alternatively, the terminal device can also determine the service selected by the user from the multiple services as the first target service according to the user operation. In this way, the terminal device can not only provide the satellite communication service for the user, but also meet the personalized needs of the user.

[0153] For example, as shown in FIG. 5, the matching module 502 obtains the satellite system information and the service information sent by the obtaining module 501. Then, the matching module 502 can match the satellite system information and the service information, obtain the matching satellite system and / or service, and send the satellite system and / or service to the selection module 503. Then, the selection module 503 can obtain the first target satellite system and / or the first target service according to the sorting result or the user selection.

[0154] In some embodiments, the terminal device can not obtain the first target satellite system or the first target service according to the satellite system information and the service information. Then, the terminal device can prompt the user to reselect the satellite system or the service. For example, the terminal device can prompt the user to reselect the satellite system or the service by displaying prompt information. In some examples, the terminal device can finally not obtain the first target satellite system or the first target service, and the terminal device can prompt the user that the satellite service cannot be used at present by means of prompt information and the like.

[0155] In some embodiments, after obtaining the first target satellite system and / or the first target service, the terminal device can establish a corresponding communication service connection and perform the required service.

[0156] For example, after obtaining the service indicated by the user to perform, the terminal device can obtain the first target satellite system, establish a communication service connection with the first target satellite system, and perform the current service.

[0157] For example, the terminal device acquires a satellite system selected by a user and acquires a first target service adapted to the satellite system. Then, the terminal device can establish a communication service connection with the satellite system selected by the user to perform the first target service.

[0158] For example, as shown in FIG. 5, the selection module 503 can send the first target satellite system and / or the first target service to the communication connection module 504 after acquiring the first target satellite system and / or the first target service according to the ranking result or the user selection. Then, the communication connection module 504 can trigger establishment of a communication service connection with the first target satellite system to perform the first target service.

[0159] In this way, the terminal device can select a more suitable satellite system to perform a corresponding service in combination with advantages and disadvantages of different satellite systems, thereby achieving rapid and stable connection of a communication service and obtaining better service execution quality.

[0160] For example, the terminal device can establish a communication service connection with different satellite systems, and the different satellite systems have different characteristics and can provide different service quality in different service scenarios. Then, selection of a suitable satellite system or service can provide better service quality for a user.

[0161] For example, the terminal device can implement functions such as short message, image, and voice information communication by connecting with a Beidou satellite. The Beidou satellite is a high-orbit satellite, and has slow flight, long distance, and limited communication capacity. The short message communication rate is usually about 40 kilobits per second (bps). Therefore, the Beidou satellite is more suitable for scenarios of sending simple text and voice information.

[0162] For example, the terminal device can implement functions such as making a call, sending a short message, and connecting to the Internet by connecting with a Tianhong satellite. The Tianhong satellite is a geosynchronous orbit satellite, and its flight period is synchronized with the rotation of the earth. The transmission rate can reach 160 kbps, supports relatively high-definition video calls and data transmission, and can realize two-way communication in a global range.

[0163] For example, the terminal device can implement functions such as sending a message, voice, image, making a call, and connecting to the Internet by connecting with a low-orbit satellite. The low-orbit satellite is close to the ground, has strong signal strength, large communication capacity, and fast transmission speed, but the time for a single satellite to pass overhead is 15-20 minutes, and the terminal device has a greater difficulty in signal acquisition.

[0164] In this way, the terminal device can intelligently select a satellite system to perform rapid service connection by combining advantages and disadvantages of different satellite systems, thereby achieving rapid and stable performance of a communication service.

[0165] The following describes a scenario of matching a satellite system based on a user-selected service and a scenario of matching a service based on a user-selected satellite system, respectively.

[0166] In some scenarios, a terminal device acquires information of a user-selected service according to a user operation. Then, the terminal device can match a satellite system suitable for the user-selected service from available satellite systems according to the user-selected service, thereby recommending a satellite system more suitable for a current service scenario for the user. The following describes the scenario of matching a satellite system based on a user-selected service through the flow shown in FIG. 6.

[0167] FIG. 6 is a flowchart of another satellite communication method provided by an embodiment of the present application. It should be noted that the method is not limited to the specific order of FIG. 6 and the following description, and it should be understood that in other embodiments, the order of some steps of the method can be exchanged with each other according to actual needs, or some steps of the method can be omitted or deleted. The method includes the following steps:

[0168] S601, a terminal device acquires service information according to a user operation.

[0169] In some embodiments, a plurality of applications are installed in the terminal device, and different applications can provide services of different service types for the user. For example, as shown in Table 1 below, the applications installed in the terminal device can belong to each of the example service types. For example, a short message application is installed in the terminal device, and the short message application provides short message services, and the service type to which the short message application belongs is the message type. For another example, a telephone application is installed in the terminal device, and the telephone application provides call services, and the service type to which the telephone application belongs is the call type.

[0170] In some embodiments, the terminal device can acquire information of different services. As described in step S402 above, the service information includes, for example, service type, service level, service name (such as application name), service requirement, and the like. For example, as shown in Table 1 below, the service requirement of the long video service installed in the terminal device includes a minimum bandwidth requirement of 1.5 Mbps for uplink and downlink services, and a requirement of small for time delay and jitter. Furthermore, according to the service requirement, the service level of the long video service can be divided into a high level. It should be understood that the content in Table 1 is only an example, and the embodiments of the present application are not limited to the classification, number, and corresponding minimum bandwidth requirements for uplink and downlink services, time delay requirements, jitter requirements, and service levels of different service types.

[0171] Table 1

[0172] In some embodiments, the application development process, the corresponding business information can be configured. Then, the terminal device can also obtain the application corresponding to the business information after downloading the application. Alternatively, the terminal device can also divide the business level according to the business requirements included in the business information according to the preset rules. Alternatively, the preset rules are related to the device performance of the terminal device, etc.

[0173] In some embodiments, the terminal device can obtain the user-selected service according to the user operation. Then, the terminal device can obtain the information of the user-selected service according to the already saved business information.

[0174] For example, the terminal device detects the operation of the user starting the short message application, and obtains the user-selected service as the short message application service. Then, the terminal device can obtain the business information of the short message application service.

[0175] Alternatively, other contents of step S601 can be referred to step S402 described above, which will not be repeated here.

[0176] S602, the terminal device obtains satellite system information.

[0177] In some embodiments, as described above in step S401, the terminal device can obtain the information of the currently available satellite system according to the current time, the location, the motion mode, the travel mode, the indoor and outdoor state, the degree of obstruction, the terminal hardware configuration, the communication package situation, etc.

[0178] For example, as shown in Table 2 below, the terminal device obtains the currently available satellite system including the Beidou satellite system, the Tianhong satellite system, and the low-orbit satellite system, and the terminal device can obtain the information of these satellite systems. For example, the satellite system information includes the information of the supported service, the satellite uplink and downlink service support bandwidth, the time delay, the jitter, etc. Among them, the bandwidth represents the maximum transmission speed of the communication service connection, the time delay represents the total time required for the data packet to be sent from the sending end to the target end, and the jitter represents the change rate of the time delay to evaluate the stability of the communication service connection. It should be understood that the contents in Table 2 are only example contents, and the embodiments of the present application are not limited to the classification, number, and different satellite systems supported by the business, and the bandwidth, time delay, and jitter of the uplink and downlink service support.

[0179] Table 2

[0180] Alternatively, other contents of step S602 can be referred to step S401 described above, which will not be repeated here.

[0181] S603, the terminal device obtains the first target satellite system according to the business information and the satellite system information.

[0182] In some embodiments, after the terminal device acquires the user-selected service information and the available satellite system information, the terminal device matches the service information and the satellite system information, and thus acquires a first target satellite system in the available satellite systems that matches the current user-selected service.

[0183] Optionally, the terminal device acquires, according to the service information, a service type of the current user-selected service. Then, the terminal device acquires, according to the satellite system information, a satellite system 1 in the currently available satellite systems that supports services of the service type. Then, the terminal device acquires, according to the satellite system information of the satellite system 1, a satellite system 2 that has a higher uplink and downlink service support bandwidth, a lower delay, and a lower jitter than the minimum requirements of the user-selected service.

[0184] It should be understood that the terminal device acquires the first target satellite system according to the service type and the service requirements, and this does not limit the filtering order of the various filtering conditions. For example, the terminal device can first acquire the satellite system 1 according to the service requirements, and then acquire the satellite system 2 from the satellite system 1 according to the service type. Alternatively, the terminal device can directly acquire the satellite system 2 according to the service type and the service requirements, i.e., without two filtering processes. In addition, the terminal device can also acquire the first target satellite system according to other information in the service information and the satellite system information, and the embodiments of the present application will not be exemplified one by one.

[0185] In some embodiments, the number of the satellite system 2 that the terminal device successfully matches is one or more. In the case where the number of the satellite system 2 is one, the terminal device can determine the one satellite system 2 as the first target satellite system. In the case where the number of the satellite system 2 is more than one, the terminal device can further filter the plurality of satellite systems 2 to acquire a final one of the first target satellite systems to be connected.

[0186] Optionally, in the case where the number of the satellite system 2 is more than one, the terminal device can sort the plurality of satellite systems 2 according to the service level corresponding to the user-selected service, and determine the one satellite system 2 at the front of the sorting as the first target satellite system. Optionally, in the case where the service level is a high level, the terminal device can sort the plurality of satellite systems 2 according to the uplink and downlink service support bandwidths of the plurality of satellite systems 2 from large to small. Then, the terminal device can determine the one satellite system 2 with the largest uplink and downlink service support bandwidth in the plurality of satellite systems 2 as the first target satellite system. Optionally, in the case where the service level is a medium level, the terminal device can randomly sort the plurality of satellite systems 2. Then, the terminal device can determine the one satellite system 2 at the front of the sorting as the first target satellite system. Optionally, in the case where the service level is a low level, the terminal device can sort the plurality of satellite systems 2 according to the uplink and downlink service support bandwidths of the plurality of satellite systems 2 from small to large. Then, the terminal device can determine the one satellite system 2 with the smallest uplink and downlink service support bandwidth in the plurality of satellite systems 2 as the first target satellite system.

[0187] In this way, the terminal device can acquire the first target satellite system most suitable for the service currently selected by the user according to the service information and the satellite system information, so as to facilitate subsequent provision of better communication quality.

[0188] For example, after detecting the operation of the user indicating running of the first application, the terminal device can adaptively select the first target satellite system most suitable for running of the first application, and trigger establishment of a communication service connection with the first target satellite system, so as to realize fast and stable connection of the communication service and acquire better service execution quality.

[0189] Optionally, the terminal device can also acquire one satellite system 2 selected by the user according to the operation of the user, and determine the satellite system 2 as the first target satellite system.

[0190] For example, as shown in FIG. 7, after acquiring the plurality of satellite systems 2, the terminal device can display the plurality of satellite systems 2. In this way, the user can select a satellite system required by the user according to the satellite system preferred by the user, so that the satellite system finally acquired can better meet the personalized needs of the user. For example, the terminal device detects the operation of the user on the low-orbit satellite communication control 71, and can acquire the first target satellite system selected by the user as the low-orbit satellite system corresponding to the low-orbit satellite communication control 71.

[0191] Optionally, the terminal device can sort the plurality of satellite systems 2. Then, the terminal device displays the plurality of satellite systems 2 in sequence according to the sorting result. In this way, the user can more conveniently select the best matching satellite system 2. For example, as shown in FIG. 7, the terminal device preferentially displays the low-orbit satellite system according to the sorting result, and then displays the Tianxiang satellite system and the Beidou satellite system in sequence. In this way, the terminal device displays the satellite system in the front of the sequence at a position easy for the user to operate, so as to increase the probability of selection of the satellite system in the front of the sequence, thereby subsequent provision of better service execution quality for the user. Optionally, in the current scenario, the terminal device can also display prompt information for prompting the user that the terminal device currently displays the plurality of satellite systems 2 in sequence (such as from top to bottom) according to the matching degree with the service selected by the user. In this way, the user can understand the sequence meaning of the plurality of satellite systems 2 displayed through the prompt information, and more clearly select the required satellite system.

[0192] In some embodiments, the terminal device acquires a matching result of a matching failure according to the service information and the satellite system information, and cannot acquire a satellite system matching the service currently selected by the user. Then, the terminal device can prompt the user that the current service cannot be executed, and can select to execute other services. For example, the terminal device can display prompt information of a satellite system selection failure.

[0193] Exemplarily, the service selected by the user is a call application service, as shown in Table 1, the service type of the call application service is a call service, the minimum bandwidth requirement of the uplink and downlink service is less than 3 Kbps, the requirement for the delay and the jitter is medium, and the service gear is medium. Then, the terminal device obtains, according to the information of the currently available satellite systems shown in Table 2, that the number of the satellite systems 1 that match successfully is multiple, including the Tianhong satellite system and the low-orbit satellite system. However, the terminal device can determine, according to the delay and the jitter included in the information of the satellite systems, that the Tianhong satellite system does not meet the delay requirement of the call service, and the low-orbit satellite system does not meet the jitter requirement of the call service, that is, none of the obtained satellite systems meets the minimum requirement of the service selected by the user. Then, the terminal device cannot obtain the satellite system 2 in the satellite system 1, that is, the terminal device cannot obtain the first target satellite system. Then, the terminal device can display the prompt information of the satellite system selection failure.

[0194] In this way, in the case where the first target satellite system cannot be obtained, the terminal device can also prompt the user to change the service in time, so as to avoid disturbing the user.

[0195] S604, the terminal device establishes a first communication service connection with the first target satellite system.

[0196] In some embodiments, after obtaining the first target satellite system, the terminal device can trigger the establishment of the first communication service connection with the first target satellite system to execute the service selected by the user.

[0197] Exemplarily, the terminal device receives the operation of the user indicating to run the first application. Then, the terminal device can obtain, according to the first application, the first target satellite system that matches the first application and can provide better communication conditions for the service running of the first application. Then, the terminal device can establish the first communication service connection with the first target satellite system to execute the service of the first application through the first communication service connection.

[0198] In this way, the terminal device can establish the communication service connection with the satellite system that is most suitable for the current service, so as to realize the rapid and stable connection of the communication service and improve the service quality.

[0199] In some embodiments, in the process of communicating based on the first communication service connection, abnormal situations such as disconnection of the first communication service connection or unstable communication can occur. Then, the terminal device can automatically switch to access other satellite systems to avoid affecting the service execution.

[0200] Optionally, as shown in FIG. 8, after the above step S604, the method further includes a step S801.

[0201] S801, in a case where the first communication service connection is disconnected or unstable, the terminal device establishes a second communication service connection with a second target satellite system.

[0202] In some embodiments, the terminal device acquires that the first communication service connection is in an abnormal scenario according to a communication quality of the first communication service connection. Then, the terminal device can select to switch to the second target satellite system to establish the second communication service connection, so as to avoid affecting execution of the user-selected service.

[0203] Optionally, the abnormal scenario includes, for example, disconnection of the first communication service connection, instability of the first communication service connection, and the like.

[0204] Optionally, as described in step S603, the terminal device sorts the multiple satellite systems 2 to be selected during acquisition of the first target satellite system. Then, in a case where the abnormal scenario occurs, the terminal device can select, according to the sorting result, the satellite system 2 ranked second as the second target satellite system.

[0205] Optionally, in a case where the number of satellite systems 2 is one, the terminal device can trigger re-execution of steps S601-S604 described above, so as to re-acquire a new first target satellite system and continue execution of the service.

[0206] It should be understood that in a case where the satellite system 2 ranked second still has the abnormal scenario such as disconnection or instability of connection, the terminal device can continue to select the satellite system 2 ranked third as the second target satellite system. Until all satellite systems 2 are in the abnormal scenario, the terminal device can trigger re-execution of steps S601-S604 described above, so as to re-acquire a new first target satellite system and continue execution of the service.

[0207] In other embodiments, the terminal device acquires that the first communication service connection is in an abnormal scenario according to a communication quality of the first communication service connection. Then, the terminal device can trigger re-execution of steps S601-S604 described above, so as to acquire a new second target satellite system and continue execution of the service. That is, regardless of whether the number of original satellite systems 2 is one or multiple, in a case where the first communication service connection corresponding to the first target satellite system is in an abnormal scenario, the terminal device can re-acquire a target satellite system to continue execution of the corresponding service.

[0208] In this way, when the abnormal scenario occurs, the terminal device can also adaptively select a satellite system that is more suitable for execution of the service selected by the user, so as to guarantee robustness of the communication service connection and communication quality.

[0209] In some embodiments, the terminal device acquires a new service selected by the user according to a user operation, and information of the service. The terminal device can acquire a matching result of information of a first target satellite system corresponding to a first communication service connection currently in a connected state and information of the new service selected by the user. If the first target satellite system matches the new service selected by the user, for example, the first target satellite system meets a service type and service requirement of the new service selected by the user, the terminal device can continue to maintain the first communication service connection and perform the new service selected by the user. If the first target satellite system does not match the new service selected by the user, for example, the first target satellite system does not meet the service type or service requirement of the new service selected by the user, the terminal device can trigger the steps S601-S604 to acquire a new first target satellite system and perform the new service selected by the user.

[0210] In this way, the terminal device can adaptively acquire a suitable satellite system to establish a communication service connection according to a service performance requirement, thereby ensuring robustness of the communication service connection.

[0211] In another scenario, the terminal device acquires information of a satellite system selected by the user according to a user operation. Then, the terminal device can acquire a service matching the satellite system selected by the user according to the satellite system selected by the user, thereby recommending a service currently more suitable for performance to the user. The scenario of matching a service based on a satellite system selected by a user is described in detail below by referring to the flow shown in FIG. 9.

[0212] FIG. 9 is a flow diagram of another satellite communication method provided by an embodiment of the present application. It should be noted that the method is not limited to the specific order shown in FIG. 9 and described below. It should be understood that in other embodiments, the order of some steps of the method can be exchanged with each other, or some steps of the method can be omitted or deleted. The method includes the following steps:

[0213] S901, the terminal device acquires a satellite system selected by the user according to a user operation.

[0214] In some embodiments, in a preset scenario, the terminal device can select to access a satellite system. Then, the terminal device acquires one or more satellite systems available in the current preset scenario, and displays the one or more satellite systems for the user to select. Then, the terminal device acquires a satellite system selected by the user. Optionally, the terminal device can also acquire information of the satellite system selected by the user.

[0215] Optionally, the preset scenario includes, for example, a scenario in which there is no ground network and the terminal device is outdoors. The ground network includes, for example, a cellular network, a wireless network, and the like.

[0216] Optionally, the terminal device obtains information of currently available satellite systems according to current time, location, motion mode, travel mode, indoor or outdoor state, and degree of obstruction, such as uplink and downlink service support bandwidth, time delay, and jitter.

[0217] Optionally, the terminal device obtains information of one satellite system from the currently available satellite systems, and obtains information of the satellite system when the user determines to select the satellite system. Alternatively, the terminal device obtains information of one satellite system from the currently available satellite systems, and directly selects the satellite system as the satellite system to be accessed.

[0218] For example, as shown in (a) of FIG. 10, the terminal device obtains that the current scenario is a preset scenario, and displays prompt information 101 to prompt the user that the current cellular network or wireless network is unavailable, and the satellite network can be connected for communication. Then, the terminal device detects operation of the user on an immediate use control 102, and determines that the user indicates to connect the satellite network. Then, the terminal device obtains currently available satellite systems, and displays the available satellite systems on an interface as shown in (b) of FIG. 10. The terminal device detects operation of the user on a low-orbit satellite communication control 103, and determines that the user indicates to access a low-orbit satellite system corresponding to the low-orbit satellite communication control 103. Then, the terminal device obtains information of the low-orbit satellite system.

[0219] In this way, the terminal device can actively prompt the user to access the satellite network in the absence of the ground network, and avoid that the terminal device cannot provide network communication services for the user.

[0220] Optionally, other contents of step S901 can refer to the above-described step S401, and details are not described herein.

[0221] S902, the terminal device obtains recommended services corresponding to the satellite system selected by the user.

[0222] In some embodiments, the terminal device can also obtain all services supported by the terminal device. Optionally, the terminal device can also obtain information of the services. Then, as described in the above-described step S403, the terminal device can match the satellite system selected by the user and all services supported by the terminal device, and obtain recommended services more suitable for the satellite system selected by the user. Optionally, the terminal device can also obtain information of the recommended services.

[0223] Optionally, the matching process of the terminal device to obtain the recommended services can refer to the above-described step S403, and details are not described herein.

[0224] Exemplarily, the terminal device determines, according to the uplink and downlink service support bandwidth, the time delay, the jitter of the satellite system selected by the user, and the minimum uplink and downlink service bandwidth requirement, the service requirement, and the service type of the service currently supported by the terminal device, the service that can be satisfied by the satellite system selected by the user from the services as the recommended service, and determines other services as non-recommended services.

[0225] In some embodiments, after the terminal device acquires the recommended service, the terminal device can display the recommended service in a preset manner. For example, the terminal device displays the recommended service in an available state, and displays the non-recommended service in an unavailable state. For another example, the terminal device displays a special mark on the identifier (such as an application icon, a card, etc.) of the displayed recommended service, so as to facilitate the user to identify the recommended service. In this way, the user can distinguish the service currently recommended for use, and facilitate selection.

[0226] In some embodiments, in the process of displaying the recommended service, the terminal device acquires the recommended service selected by the user and the information of the recommended service selected by the user according to the user operation.

[0227] Exemplarily, as shown in FIG. 11, the terminal device acquires the recommended service from all services supported by the terminal device according to the low-orbit satellite system currently selected by the user, and displays the recommended service in an available state, and displays the non-recommended service in an unavailable state. For example, the display effect of the non-recommended service in the unavailable state is gray display, prompting the user that these services cannot be used or are not recommended to be used.

[0228] Then, in response to the operation of the user on the gallery application, it can be determined that the recommended application selected by the user is the gallery application.

[0229] Optionally, other contents of step S902 can refer to the above-described steps S402 and S403, and will not be described herein again.

[0230] S903, the terminal device establishes a communication service connection with the satellite system selected by the user according to the recommended service selected by the user.

[0231] In some embodiments, after the terminal device acquires the satellite system selected by the user and the recommended service, the terminal device can establish a communication service connection with the satellite system selected by the user, and execute the recommended service selected by the user.

[0232] In some embodiments, the terminal device can first establish a connection with the satellite system selected by the user after obtaining the satellite system selected by the user. Then, the terminal device can perform the step S902 to obtain the recommended service selected by the user. Then, the terminal device can directly perform the service selected by the user based on the connection with the satellite system selected by the user. That is, the embodiments of the present application do not limit the execution order between the step A of selecting the recommended service by the user and the step B of establishing the connection between the terminal device and the satellite system selected by the user.

[0233] In this way, the terminal device can implement service recommendation and guidance according to the satellite system selected by the user, thereby realizing fast and stable connection of the communication service and improving the service execution quality.

[0234] In some schemes, the embodiments of the present application can be combined, and the combined scheme can be implemented. Optionally, some operations in the processes of the method embodiments are combined, and / or the order of some operations is changed. In addition, the execution order between the steps of each process is only exemplary, and does not constitute a limitation on the execution order between the steps, and other execution orders between the steps can also be adopted.

Those skilled in the art can think of various ways to reorder the operations described herein.

[0235] In addition, some steps in the method embodiments can be equivalently replaced by other possible steps. Alternatively, some steps in the method embodiments can be optional and can be deleted in some use scenarios. Alternatively, other possible steps can be added to the method embodiments.

[0236] In addition, each method embodiment can be implemented individually or in combination.
