[0093] Low Earth Orbit (LEO) satellite communication systems: located at altitudes of 500 km to 2000 km above the Earth's surface, they offer relatively low transmission latency and power consumption, but the coverage area of ​​each satellite is also relatively small.

[0094] Medium Earth Orbit (MEO) satellite communication systems: 2000-20000 km above the ground, with longer transmission delays than low Earth orbit satellites, but also a wider coverage area;

[0095] Geostationary Earth Orbit (GEO): 35,800 km above the ground, i.e., geostationary orbit. Theoretically, global coverage can be achieved with three GEO satellites.

[0096] It should be noted that LEO satellites have limited coverage, move at high speeds, and have relatively poor signal continuity. LEO satellites, on the other hand, are closer to Earth, resulting in higher transmission rates and lower latency.

[0134] Table 1

[0135] In some implementations, after the terminal starts the first application, the specific process of the above S230 can be shown in Figure 3.

[0136] In some embodiments, the above-described S220 may specifically include:

[0137] The terminal obtains the first information from its local storage; or...

[0138] The terminal receives the first information from the first network device.

[0139] In this embodiment, the terminal can obtain first information from local (such as as agreed in the protocol), and then determine whether to change the orbit or satellite after launching the application (such as APP) based on the first information, so as to ensure the normal transmission of the launched application.

[0140] In this embodiment, the terminal can receive first information from the first network device, thereby determining whether to change the orbit or satellite after launching an application (such as an APP) based on the first information, so as to ensure the normal transmission of the launched application.

[0141] Optionally, the first network device may be an AMF (Active Mobile Provider), or the first network device may be a Mobility Management Entity (MME).

[0142] In some embodiments, the wireless communication method 200 further includes:

[0143] The terminal sends a first instruction message to the first network device;

[0144] Wherein, the first indication information is used to indicate that the terminal supports multiple satellites, or the first indication information is used to indicate that the terminal supports movement between multiple satellites, or the first indication information is used to indicate that the terminal supports changes between multiple satellites, or the first indication information is used to indicate that the terminal supports multiple orbits, or the first indication information is used to indicate that the terminal supports movement between multiple orbits, or the first indication information is used to indicate that the terminal supports changes between multiple orbits.

[0145] In this embodiment, the terminal sends first indication information to the first network device, so that the first network device or the second network device (the first network device forwards the first indication information to the second network device) can generate first information based on the first indication information.

[0146] Optionally, the first network device can be an AMF or MME, or other network elements (such as a base station), and this application embodiment does not limit this.

[0147] Optionally, the second network device may be a Policy Control function (PCF), Unified Data Management (UDM), Application Function (AF), Policy and Charging Rules Function (PCRF), or Home Subscriber Server (HSS).

[0148] In some implementations, taking the first network device as an AMF as an example, the terminal initiates a registration process or a Mobility Registration Update (MRU) process. The registration message includes a UE policy container, which contains first indication information. The first indication information is used to indicate that the terminal supports multiple satellites, or, the first indication information is used to indicate that the terminal supports movement between multiple satellites, or, the first indication information is used to indicate that the terminal supports changes between multiple satellites, or, the first indication information is used to indicate that the terminal supports multiple orbits, or, the first indication information is used to indicate that the terminal supports movement between multiple orbits, or, the first indication information is used to indicate that the terminal supports changes between multiple orbits.

[0149] In some implementations, taking the first network device as an AMF as an example, the terminal initiates a registration process or a mobility registration update (MRU) process. The terminal carries first indication information through its mobility management (MM) capability. The first indication information is used to indicate that the terminal supports multiple satellites, or, the first indication information is used to indicate that the terminal supports movement between multiple satellites, or, the first indication information is used to indicate that the terminal supports changes between multiple satellites, or, the first indication information is used to indicate that the terminal supports multiple orbits, or, the first indication information is used to indicate that the terminal supports movement between multiple orbits, or, the first indication information is used to indicate that the terminal supports changes between multiple orbits.

[0150] In some embodiments, in S230 above, the terminal determines, based on the first information, whether to change to a second orbit or a satellite in a second orbit, or to remain on the first satellite, including at least one of the following:

[0151] If the information of the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines that it has been changed to the second orbit or a satellite in the second orbit;

[0152] If the information of the satellite associated with the first application includes the first orbit or the first satellite, the terminal determines to remain on the first satellite;

[0153] If the priority of the first application is higher than that of the second application, and the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines to change to the second orbit or the satellite of the second orbit;

[0154] If the priority of the first application is higher than that of the second application, and the satellite associated with the first application includes the first orbit or the first satellite, the terminal determines to remain on the first satellite.

[0155] If the priority of the first application is lower than that of the second application, and the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines to remain on the first satellite.

[0156] Wherein, the satellites in the second orbit are included in the information of the satellites associated with the first application, or the second orbit is included in the information of the satellites associated with the first application, the first application is the application that the terminal is about to launch, or the first application is the application that the terminal has just launched, and the second application is the application that the terminal has already launched.

[0157] In some implementations, if the information of the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines to change to the second orbit or a satellite in the second orbit, thereby ensuring the normal transmission of the first application and improving satellite communication performance and user experience.

[0158] In some implementations, if the information of the satellite associated with the first application includes the first orbit or the first satellite, the terminal is determined to remain on the first satellite, thereby avoiding changes to the orbit or satellite, ensuring the normal transmission of the services corresponding to the first application, and improving satellite communication performance and user experience.

[0159] In some implementations, if the priority of the first application is higher than that of the second application, and the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines to change to the second orbit or a satellite in the second orbit. This can ensure the normal transmission of the service corresponding to the first application, and also improve satellite communication performance and user experience.

[0160] In some implementations, if the priority of the first application is higher than that of the second application, and the satellite associated with the first application includes the first orbit or the first satellite, the terminal is determined to stay on the first satellite. This can avoid changing the orbit or satellite, ensure the normal transmission of the service corresponding to the first application, and improve satellite communication performance and user experience.

[0161] In some implementations, if the priority of the first application is lower than that of the second application, and the satellite associated with the first application does not include the first orbit or the first satellite, the terminal will remain on the first satellite. This avoids changing the orbit or satellite and ensures the normal transmission of the services corresponding to the second application. In this case, the terminal will stop transmitting the services corresponding to the first application or stop running the first application.

[0162] For example, if the terminal is currently using APP-1 in GEO mode, and the user launches APP-2, since APP-1 has a higher priority and APP-2 cannot use GEO mode, the terminal will maintain GEO mode and notify the user that APP-2 cannot be used.

[0163] For example, if the terminal is currently using APP-1 in GEO, and the user starts APP-3, since APP-1 has a higher priority and APP-3 can use GEO, the terminal remains in GEO, and APP-3 uses GEO for communication.

[0164] For example, if the terminal is currently using APP-3 in LEO and the user launches APP-2, since APP-2 has a higher priority and can use MEO, the terminal will reselect or switch to MEO to ensure that APP-2 can run normally.

[0165] In some embodiments, if the terminal determines that the satellite has changed to the second orbit or the satellite in the second orbit, the wireless communication method 200 further includes:

[0166] The terminal sends a first message to the first access network device; wherein the first message is used to instruct the terminal to be redirected to the second orbit, or the first message is used to instruct the terminal to be redirected to a satellite in the second orbit;

[0167] The terminal receives a second message from the first access network device, and the terminal accesses the satellite in the second orbit according to the second message; or,

[0168] The terminal receives a third message from the first access network device, and the terminal maintains its connection with the first satellite according to the third message.

[0169] In this embodiment, the terminal sends a first message to the first access network device; the terminal receives a second message from the first access network device, and the terminal accesses a satellite in a second orbit according to the second message; or, the terminal receives a third message from the first access network device, and the terminal maintains a connection with the first satellite according to the third message. This ensures the normal transmission of services corresponding to the first application, improving the user experience.

[0170] Optionally, the first message may be a Radio Resource Control (RRC) message, for example, the first message may be a UE Assistance Information message.

[0171] Optionally, the second message can be an RRC message, for example, an RRC release message.

[0172] Optionally, the third message can be an RRC message.

[0173] Optionally, the first access network device may be deployed inside the first satellite, or the first access network device may be deployed on the ground.

[0174] In some implementations, taking GEO as the first track, LEO as the second track, and GEO RAN as the first access network device as the first example, the first message carries two parameters: a redirect required indication and "LEO" information.

[0175] In some implementations, taking GEO as the first track, LEO as the second track, and GEO RAN as the first access network device as an example, the first message carries one parameter: "LEO" is carried in the redirect info, as follows:

[0182] Wherein, the at least one cell is some or all of the cells corresponding to the satellites in the second orbit, or the at least one cell is some or all of the cells corresponding to the satellites in the second orbit.

[0183] In some implementations, after obtaining the second information, the terminal can learn that the network side has agreed to perform the redirection, thereby allowing the terminal to access the satellite in the second orbit.

[0184] In some implementations, after obtaining information about the second orbit, the terminal can determine the specific satellite to be accessed in the second orbit based on that information.

[0185] In some implementations, after obtaining information about the satellites in the second orbit, the terminal can access the satellites in the second orbit based on the obtained information.

Alternatively, the time information described in the embodiments of this application can be timer information, such as when access is available when the timer expires.

[0271] In some embodiments, the first information may be an enhanced terminal path selection policy (URSP) rule, or the first information may be a multi-orbit selection rule.

[0272] In some embodiments, the terminal determines, based on first information and information from the first application, a satellite that has been moved to the second orbit or the second orbit, including:

[0273] If the information of the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines that it has been changed to the second orbit or a satellite in the second orbit;

[0274] If the priority of the first application is higher than that of the second application, and the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines to change to the second orbit or the satellite of the second orbit;

[0275] The second application is an application that has been started on the terminal.

[0276] In some implementations, if the information of the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines to change to the second orbit or a satellite in the second orbit, thereby ensuring the normal transmission of the service corresponding to the first application, and also improving satellite communication performance and user experience.

[0277] In some implementations, if the priority of the first application is higher than that of the second application, and the satellite associated with the first application does not include the first orbit or the first satellite, the terminal determines to change to the second orbit or a satellite in the second orbit. This can ensure the normal transmission of the service corresponding to the first application, and also improve satellite communication performance and user experience.

[0278] For example, if the terminal is currently using APP-1 in GEO mode, and the user launches APP-2, since APP-1 has a higher priority and APP-2 cannot use GEO mode, the terminal will maintain GEO mode and notify the user that APP-2 cannot be used.

[0279] For example, if the terminal is currently using APP-1 in GEO, and the user starts APP-3, since APP-1 has a higher priority and APP-3 can use GEO, the terminal remains in GEO, and APP-3 uses GEO for communication.

[0280] For example, if the terminal is currently using APP-3 in LEO and the user launches APP-2, since APP-2 has a higher priority and can use MEO, the terminal will reselect or switch to MEO to ensure that APP-2 can run normally.

[0371] Example 1, as shown in Figure 7, may include some or all of the following S1-1 to S1-6.

[0372] S1-1. The terminal registers to the first track, for example, the first track is GEO.

[0375] S1-3. The terminal's operating system (OS) determines, based on the first information, whether the priority of the first application is higher than the priority of the already started second application.

[0376] Optionally, the first information includes at least one of the following: information about at least one application, priority information corresponding to each application in the at least one application, and information about the satellite associated with the at least one application.

[0377] The at least one application includes the first application.

[0385] Optionally, the satellite information may include satellite name, satellite identifier, RAT type, etc., and the orbit information may include GEO, MEO, or LEO.

[0386] It should be noted that satellites in each orbit can be identified by their RAT type; or, the orbit in which a satellite is located can be determined by its RAT type.

[0389] S1-4. If the terminal's OS determines that the priority of the first application is higher than the priority of the already started second application, the terminal's OS will further determine whether a track change is necessary.

[0390] S1-5. If the terminal's OS determines that it does not need to change tracks, the terminal remains on the first track;

[0391] Alternatively, in S1-4, if the terminal's OS determines that the priority of the first application is lower than the priority of the already started second application, then the terminal remains on the first track.

[0395] For example, if the terminal is currently using APP-1 in GEO mode, and the user launches APP-2, since APP-1 has a higher priority and APP-2 cannot use GEO mode, the terminal will maintain GEO mode and notify the user that APP-2 cannot be used.

[0396] For example, if the terminal is currently using APP-1 in GEO, and the user starts APP-3, since APP-1 has a higher priority and APP-3 can use GEO, the terminal remains in GEO, and APP-3 uses GEO for communication.

[0397] For example, if the terminal is currently using APP-3 in LEO and the user launches APP-2, since APP-2 has a higher priority and can use MEO, the terminal will reselect or switch to MEO to ensure that APP-2 can run normally.

[0398] In Example 1, when an application is launched on a terminal, it can be determined whether a track change is needed to improve the user experience.
