[0002] With the rapid development of communication technology, number portability has become a common and convenient service.

During the transmission of satellite messages, if the recipient is not connected to the corresponding network, the message will be stored in the terrestrial network. When the user transfers their number to another network, the way the original operator handles these satellite messages stored in the terrestrial network directly affects the user's experience and rights.

[0067] In order to make the purpose, technical solution and advantages of the present disclosure more obvious, the exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described here.

[0068] like Figure 1 As shown, the cross-network satellite messaging system according to the embodiment of the present disclosure is used to realize message transmission between different networks. The satellite messaging system 100 is mainly composed of a first ground network device 101, a second ground network device 102 and a third satellite network device 103. Among them, the first ground network device 101 can be a base station, a gateway or other device that can communicate with a ground network (such as a cellular network, a Wi-Fi network, etc.), which is responsible for sending and receiving satellite messages from a satellite network. The second ground network device is similar to the first ground network device, but it serves a different ground network and is responsible for sending and receiving satellite messages from a satellite network. The third satellite network device 103 realizes the transmission of satellite messages through satellite communication technology. It can receive satellite messages from a ground network device and forward them to another ground network device, thereby realizing cross-network message transmission.

[0069] It is easy to understand that Figure 1 The devices related to the inter-network satellite message are only schematically shown, and the communication system for implementing message transmission between different networks is not limited thereto.

[0070] In an embodiment of the present disclosure, when a terminal device is ported from a first ground network device 101 (i.e., the original operator's ground network) to a second ground network device 102, the satellite message stored in the first ground network device 101 will be discarded or retained by the first ground network device 101. If discarded, the terminal device cannot obtain the satellite message stored in the first ground network device 101, the user experience is poor, and the user's complaints against the operator will increase. If retained, because the terminal device has been ported to the second ground network device 102 (i.e., the existing operator's ground network), even if the first ground network device 101 retains the satellite information, the user cannot obtain it, the user experience is poor, and the user's complaints against the operator will increase. Secondly, the retention of satellite messages will also occupy the original operator's ground network resources. And the original operator storing the message information of the deregistered user may be suspected of infringing the user's privacy.

[0071] In order to solve the above problems, the present disclosure provides a cross-network message synchronization method.

[0072] Figure 2 is a flowchart illustrating a method for synchronizing messages across networks according to an embodiment of the present disclosure.

[0073] like Figure 2 As shown, a cross-network message synchronization method can be executed by a first ground network device, and the method specifically includes the following steps.

[0074] Step S201, determining whether the terminal device communicating with the second ground network device retains relevant information of the satellite message service.

[0075] In an embodiment of the present disclosure, the terminal device initially communicates with a first ground network device. After the terminal device switches from the first ground network device to communicating with a second ground network device, the first ground network device performs user service verification on the terminal device to determine whether the terminal device retains relevant information about the satellite message service.

[0076] In actual application scenarios, the terminal device initially communicates with the first ground network device. When the terminal device is ported to the second ground network device, the first ground network device verifies the user service of the terminal device to determine whether the terminal device has the relevant information of the satellite messaging service. Here, "number portability" means that the user of the terminal device keeps the original mobile phone number unchanged, but changes the service provider (from the first ground network device to the second ground network device).

[0077] Here, satellite messages include but are not limited to existing Beidou short messages, Beidou short messages, Beidou short messages, Beidou satellite messages, satellite emergency messages, satellite emergency messages, satellite broadcast messages, Starlink messages, satellite Starlink messages, and satellite network short messages, short messages, MMS messages, and multimedia messages. Relevant information of satellite message services includes but is not limited to user information (such as user code numbers, etc.), user subscription information (such as satellite message service IDs subscribed by users, the number of retained satellite messages, etc.), satellite messages (such as message IDs, message contents, etc.), etc.

[0078] Step S202, executing an operation of synchronizing the satellite message service related information with the second ground network device or the third satellite network device.

[0079] In an embodiment of the present disclosure, after the first ground network device determines whether the terminal device communicating with the second ground network device retains relevant information of the satellite message service, the first ground network device evaluates whether it is necessary to synchronize the relevant information of the satellite message service with the second ground network device or the third satellite network device based on the confirmed information.

[0080] Here, the first ground network device and the second ground network device can be network devices that provide ground fixed communication network services and ground mobile network communication services for terminal devices, and can directly or indirectly receive satellite messages sent by terminal devices under ground network access; or directly or indirectly send satellite messages to terminal devices under ground network access; or can send satellite messages to third satellite network devices; or receive satellite messages sent by third satellite network devices; or directly or indirectly store satellite messages. The third satellite network device can be a satellite message network device located on the ground or on a satellite that is connected to the ground network, and can directly or indirectly receive satellite messages sent by terminal devices under satellite network access; or directly or indirectly send satellite messages to terminal devices under satellite network access; or send satellite messages to ground network devices (such as: the first ground network device, the second ground network device); or receive satellite messages sent by ground network devices (such as: the first ground network device, the second ground network device); or directly or indirectly store satellite messages. The third satellite network device includes but is not limited to the existing satellite network operation platform, Beidou civil short message communication operation service system, satellite network platform, Starlink network platform, etc.

[0081] In summary, according to the technical solution provided by the embodiment of the present disclosure, the first ground network device confirms whether the terminal device that communicates from the first ground network device to the second ground network device retains relevant information of the satellite message service, and evaluates whether it is necessary to synchronize this information with the second ground network device or the third satellite network device based on the confirmed information, thereby realizing seamless transmission of satellite messages between different network devices. Even if the user transfers his number to another network, his satellite message can be synchronized to the new operator or related network equipment in a timely manner, thereby protecting the user's rights and experience.

[0082] Figure 3 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0083] like Figure 3 As shown, according to the cross-network message synchronization method of the embodiment of the present disclosure, the operation of synchronizing the relevant information of the satellite message service with the second ground network device or the third satellite network device specifically includes the following steps.

[0084] Step S301, while retaining the relevant information of the satellite message service, sending a first request message to the second ground network device, the first request message being used to request the relevant information of the synchronous satellite message service.

[0085] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device, and finds the relevant information of the satellite message service retained in the terminal device according to the verification result. And informs the second ground network device of the discovery. At the same time, the first ground network device sends a first request message to the second ground network device, and the first request message is used to request the second ground network device to synchronize the relevant information of the satellite message service retained in the first ground network device.

[0086] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (e.g., in response to a request from the second ground network device) send a first request message to the second ground network device. Here, the first request message may include one or more of user information corresponding to the terminal device (e.g., user code number, etc.), user subscription information (e.g., satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0087] Step S302, in response to the first response information returned by the second ground network device after verifying the first request information, synchronize the relevant information of the satellite message service with the second ground network device, and the first response information is used to indicate that the second ground network device agrees to synchronize the relevant information of the satellite message service.

[0088] In the embodiment of the present disclosure, after receiving the first request information, the second ground network device will identify and parse the first request information, verify the content of the first request information, and after the verification is passed, generate the first response information according to the first request information, and send the first response information to the first ground network device, and the first response information clearly indicates that the second ground network device agrees to synchronize the relevant information of the satellite message service. Next, the first ground network device will start the process of synchronizing the relevant information of the satellite message service with the second ground network device according to the received first response information.

[0089] In summary, according to the technical solution provided by the embodiment of the present disclosure, the present disclosure realizes the seamless connection of satellite message services between different networks through information synchronization between the first ground network device and the second ground network device. This helps to improve the user experience and enables users to maintain the continuity and consistency of messages in different network environments.

[0090] Furthermore, the first ground network device will clean up the relevant information of the satellite message service, which may include user subscription information (such as the satellite message service ID subscribed by the user, the number of retained satellite messages, etc.), satellite messages (such as message ID, message content, etc.) and other information. Storing sensitive information (such as user subscription status and message content) will bring security risks. Timely cleaning of this information can reduce the risk of data leakage and enhance the security of user data. At the same time, it can reduce the storage space occupied.

[0091] Figure 4 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0092] like Figure 4 As shown, according to the cross-network message synchronization method of the embodiment of the present disclosure, the operation of synchronizing the relevant information of the satellite message service with the second ground network device or the third satellite network device specifically includes the following steps.

[0093] Step S401, when no relevant information of the satellite messaging service is retained but the terminal device has subscribed to or has a subscription record for the satellite messaging service, a second request message is sent to a second ground network device, the second request message being used to request termination of relevant information of the synchronous satellite messaging service.

[0094] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, when it is found that no relevant information of the satellite message service of the terminal device is retained but the terminal device has subscribed to or has subscribed to the satellite message service, the second network device will be informed of the discovery. At the same time, the first ground network device sends a second request message to the second ground network device, and the second request message is used to request the second ground network device to end the synchronization of relevant information of the satellite message service.

[0095] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (e.g., in response to a request from the second ground network device) send a second request message to the second ground network device. Here, the second request message may include one or more of user information corresponding to the terminal device (e.g., user code number, etc.), user subscription information (e.g., satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0096] Step S402, in response to the second response information returned by the second ground network device after verifying the second request information, the operation of terminating the relevant information of the synchronous satellite message service, the second response information is used to indicate that the second ground network device agrees to terminate the relevant information of the synchronous satellite message service.

[0097] In an embodiment of the present disclosure, after receiving the second request information, the second ground network device will parse and identify the second request information, and verify the content of the second request information. When the verification is passed, a second response information will be generated and sent to the first ground network device. The second response information is used to indicate that the second ground network device agrees to terminate the relevant information of the synchronous satellite message service. The first ground network device will end the synchronization process with the second ground network device according to the received second response information.

[0098] In summary, according to the embodiments provided by the present invention, through the information interaction between the first ground network device and the second ground network device, the synchronization of satellite message service information that is no longer needed can be terminated in time, thereby avoiding the transmission of invalid data between networks, reducing the service problems that users may encounter due to inconsistent or erroneous information, and improving the user's service experience.

[0099] Figure 5 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0100] like Figure 5As shown, according to the cross-network message synchronization method of the embodiment of the present disclosure, the operation of synchronizing the relevant information of the satellite message service with the second ground network device or the third satellite network device specifically includes the following steps.

[0101] Step S501: while retaining the relevant information of the satellite message service, sending a third request message to a third satellite network device, where the third request message is used to request the relevant information of the synchronous satellite message service.

[0102] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device, and finds relevant information of the satellite message service of the terminal device according to the verification result, and notifies the third satellite network device of the discovery. At the same time, the first ground network device sends a third request information to the third satellite network device, and the third request information is used to request the third satellite network device to synchronize the relevant information of the satellite message service of the first ground network device.

[0103] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (e.g., in response to a request from the third satellite network device) send a third request message to the third satellite network device. Here, the third request message may include one or more of user information corresponding to the terminal device (e.g., user code number, etc.), user subscription information (e.g., satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0104] Step S502, in response to the third response information returned by the third satellite network device after verifying the third request information, synchronize the relevant information of the satellite message service with the third satellite network device, wherein the third response information is used to indicate that the third satellite network device agrees to synchronize the relevant information of the satellite message service.

[0105] In the embodiment of the present disclosure, after receiving the third request information, the third satellite network device will identify and parse the third request information, verify the content of the third request information, and when the verification is passed, generate third response information according to the third request information, and send the third response information to the first ground network device, and the third response information clearly indicates that the third satellite network device agrees to synchronize the relevant information of the satellite message service. Next, the first ground network device will start the process of synchronizing the relevant information of the satellite message service with the third satellite network device according to the received third response information.

[0106] In summary, according to the technical solution provided by the embodiment of the present disclosure, the present disclosure realizes the seamless connection of satellite message services between different networks through information synchronization between the first ground network device and the third satellite network device. This helps to improve the user experience and enables users to maintain the continuity and consistency of messages in different network environments.

[0107] Figure 6 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0108] like Figure 6 As shown, according to the cross-network message synchronization method of the embodiment of the present disclosure, the operation of synchronizing the relevant information of the satellite message service with the second ground network device or the third satellite network device specifically includes the following steps.

[0109] Step S601, when no satellite messaging service related information is retained but the terminal device has subscribed to or has a satellite messaging service subscription record, a fourth request message is sent to a third satellite network device, the fourth request message being used to request termination of the synchronous satellite messaging service related information.

[0110] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, when it is found that no relevant information of the satellite message service of the terminal device is retained but the terminal device has subscribed to or has subscribed to the satellite message service, the third satellite network device will be informed of the discovery. At the same time, the first ground network device sends a fourth request information to the third satellite network device, and the fourth request information is used to request the third satellite network device to end the synchronization of relevant information of the satellite message service.

[0111] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (for example, in response to a request from the third satellite network device) send a fourth request message to the third satellite network device. Here, the fourth request message may include one or more of user information corresponding to the terminal device (for example, user code number, etc.), user subscription information (for example, satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0112] Step S602, in response to the fourth response information returned by the third satellite network device after verifying the fourth request information, the operation of terminating the relevant information of the synchronous satellite message service, the fourth response information is used to indicate that the third satellite network device agrees to terminate the relevant information of the synchronous satellite message service.

[0113] In an embodiment of the present disclosure, after receiving the fourth request information, the third satellite network device will parse and identify the fourth request information, and verify the content of the fourth request information. When the verification is passed, a fourth response information will be generated and sent to the first ground network device. The fourth response information is used to indicate that the third satellite network device agrees to terminate the relevant information of the synchronous satellite message service. The first ground network device will end the process of the relevant information of the synchronous satellite message service between the third satellite network device and the third satellite network device according to the received fourth response information.

[0114] Figure 7 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0115] like Figure 7 As shown, according to the cross-network message synchronization method of the embodiment of the present disclosure, the operation of synchronizing the relevant information of the satellite message service with the second ground network device or the third satellite network device specifically includes the following steps.

[0116] Step S701: while retaining the relevant information of the satellite message service, sending fifth request information to the third satellite network device, where the fifth request information is used to request the relevant information of the synchronous satellite message service.

[0117] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device, and finds relevant information of the satellite message service of the terminal device according to the verification result, and notifies the third satellite network device of the discovery. At the same time, the first ground network device sends fifth request information to the third satellite network device, and the fifth request information is used to request the second ground network device to synchronize the relevant information of the satellite message service retained in the first ground network device.

[0118] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (for example, in response to a request from the third satellite network device) send a fifth request message to the third satellite network device. Here, the fifth request message may include one or more of user information corresponding to the terminal device (for example, user code number, etc.), user subscription information (for example, satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0119] Step S702: in response to the fifth response information returned by the third satellite network device after verifying the fifth request information, synchronize the relevant information of the satellite message service with the second ground network device.

[0120] In the embodiment of the present disclosure, after receiving the fifth request information, the third satellite network device will identify and parse the third request information, verify the content of the fifth request information, and return the fifth response information to the first ground network device after the verification is passed. The fifth response information clearly indicates that the second ground network device agrees to synchronize the relevant information of the satellite message service. Next, the first ground network device will start the process of synchronizing the relevant information of the satellite message service with the second ground network device according to the received fifth response information.

[0121] Furthermore, the fifth response information is generated by the second ground network device after verifying the fifth request information forwarded by the third satellite network device, and is used to indicate that the second ground network device agrees to synchronize the relevant information of the satellite message service.

[0122] Specifically, after the third satellite network receives the fifth request information, after verifying the fifth request information, the fifth request information will be forwarded to the second ground network device. After receiving the fifth request information, the second ground network device will identify and parse the fifth request information, verify the content of the fifth request information, and when the verification is successful, it will generate a fifth response information and return the fifth response information to the third satellite network device. The fifth response information clearly indicates that the second ground network device agrees to synchronize the relevant information of the satellite message service. When the third satellite network device receives the fifth response information, it will verify the fifth response information, and after the verification is successful, it will send the fifth response information to the first ground network device.

[0123] In summary, according to the technical solution provided by the present invention, the first ground network device synchronizes relevant information of the satellite message service with the second ground network device through the third satellite network device, thereby realizing cross-network satellite message service synchronization, ensuring that when users change network service providers, their satellite message services can be seamlessly connected to avoid service interruptions.

[0124] Figure 8 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0125] like Figure 8 As shown, according to the cross-network message synchronization method of the embodiment of the present disclosure, the operation of synchronizing the relevant information of the satellite message service with the second ground network device or the third satellite network device specifically includes the following steps.

[0126] Step S801, when no relevant information of the satellite messaging service is retained but the terminal device has subscribed to or has a subscription record for the satellite messaging service, a sixth request message is sent to a third satellite network device, the sixth request message being used to request termination of synchronization of relevant information of the satellite messaging service.

[0127] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, when it is found that no relevant information of the satellite message service of the terminal device is retained but the terminal device has subscribed or has subscribed to the satellite message service, the third satellite network device will be informed of the discovery. At the same time, the first ground network device sends a sixth request information to the third satellite network device, and the sixth request information is used to request the third satellite network device to end the synchronization of relevant information of the satellite message service.

[0128] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (for example, in response to a request from the third satellite network device) send a sixth request message to the third satellite network device. Here, the sixth request message may include one or more of user information corresponding to the terminal device (for example, user code number, etc.), user subscription information (for example, satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0129] Step S802, in response to the sixth response information returned by the third satellite network device in response to the sixth request information verification, the operation of terminating the relevant information of the synchronous satellite message service, the sixth response information is used to indicate that the third satellite network device agrees to terminate the relevant information of the synchronous satellite message service.

[0130] In an embodiment of the present disclosure, after receiving the sixth request information, the third satellite network device will parse and identify the sixth request information, and verify the content of the sixth request information. When the verification is passed, the sixth response information will be generated and sent to the first ground network device. The sixth response information is used to indicate that the third satellite network device agrees to terminate the relevant information of the synchronous satellite message service. The first ground network device will end the process of the relevant information of the synchronous satellite message service between the first ground network device and the second ground network device according to the received sixth response information.

[0131] In summary, according to the technical solution provided by the embodiment of the present disclosure, the present disclosure establishes an association between the first ground network device and the second ground network device through a third satellite network device, so that the terminal device can migrate between different ground network devices while maintaining the continuity or timely termination of its satellite message service, which reflects the flexibility of service provision and enhances user satisfaction and trust in the service.

[0132] Fig. 9 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0133] like Fig. 9As shown, a cross-network message synchronization method can be executed by a second ground network device, and the method specifically includes the following steps.

[0134] Step S901, determining whether the terminal device communicating with the second ground network device retains the relevant information of the satellite message service.

[0135] In the embodiment of the present disclosure, the terminal device initially communicates with the first ground network device. After the terminal device switches from the first ground network device to communicate with the second ground network device, the first ground network device verifies the user service corresponding to the terminal device to determine whether the terminal device retains the relevant information of the satellite message service, and informs the second ground network device of the confirmed information.

[0136] In actual application scenarios, the terminal device initially communicates with the first ground network device. When the terminal device is ported to the second ground network device, the first ground network device verifies the user service corresponding to the terminal device to determine whether the terminal device retains the relevant information of the satellite messaging service. Here, "number portability" means that the user of the terminal device keeps the original mobile phone number unchanged, but changes the service provider (from the first ground network device to the second ground network device).

[0137] Here, satellite messages include but are not limited to existing Beidou short messages, Beidou short messages, Beidou short messages, Beidou satellite messages, satellite emergency messages, satellite emergency messages, satellite broadcast messages, Starlink messages, satellite Starlink messages, and satellite network short messages, short messages, MMS messages, and multimedia messages. Relevant information of satellite message services includes but is not limited to user information (such as user code numbers, etc.), user subscription information (such as the satellite message service ID subscribed by the user, the number of retained satellite messages, etc.), satellite messages (such as message IDs, message contents, etc.), etc.

[0138] Step S902, executing an operation of synchronizing the satellite message service related information with the first ground network device.

[0139] In an embodiment of the present disclosure, after determining whether a terminal device communicating with a second ground network device retains relevant information of a satellite message service, the first ground network device notifies the second ground network device of confirmation information. The second ground network device evaluates whether it needs to synchronize relevant information of the satellite message service with the first ground network device based on the confirmed information.

[0140] Here, the first ground network device and the second ground network device can be network devices that provide ground fixed communication network services and ground mobile network communication services for terminal devices, and can directly or indirectly receive satellite messages sent by terminal devices under ground network access; or directly or indirectly send satellite messages to terminal devices under ground network access; or can send satellite messages to third satellite network devices; or receive satellite messages sent by third satellite network devices; or directly or indirectly store satellite messages. The third satellite network device can be a satellite message network device located on the ground or on a satellite that is connected to the ground network, and can directly or indirectly receive satellite messages sent by terminal devices under satellite network access; or directly or indirectly send satellite messages to terminal devices under satellite network access; or send satellite messages to ground network devices (such as: the first ground network device, the second ground network device); or receive satellite messages sent by ground network devices (such as: the first ground network device, the second ground network device); or directly or indirectly store satellite messages. The third satellite network device includes but is not limited to the existing satellite network operation platform, Beidou civil short message communication operation service system, satellite network platform, Starlink network platform, etc.

[0141] In summary, according to the technical solution provided by the embodiment of the present disclosure, the first ground network device confirms whether the terminal device that communicates from the first ground network device to the second ground network device retains the relevant information of the satellite message service, and notifies the second ground network device of the confirmed information. The second ground network device evaluates whether it needs to synchronize this information with the first ground network device based on the confirmed information, thereby realizing the seamless transmission of satellite messages between different network devices. Even if the user transfers his number to another network, his satellite message can be synchronized to the new operator or related network device in a timely manner, thereby protecting the rights and interests and experience of the user.

[0142] Further, performing an operation of synchronizing the satellite message service-related information with the first ground network device includes:

[0143] In the case of retaining the relevant information of the satellite message service, a first request message is received from the first ground network device, and the first request message is used to request the relevant information of the synchronous satellite message service. After the first request message is verified, a first response message is sent to the first ground network device to synchronize the relevant information of the satellite message service with the first ground network device, and the first response message is used to indicate that the second ground network device agrees to synchronize the relevant information of the satellite message service.

[0144] Specifically, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device, and finds the relevant information of the satellite message service of the terminal device according to the verification result. And informs the second ground network device of the discovery. The first ground network device sends a first request message to the second ground network device, and the first request message is used to request the second ground network device to synchronize the relevant information of the satellite message service retained in the first ground network device. After receiving the first request message, the second ground network device will identify and parse the first request message, and verify the content of the first request message. When the verification is passed, it will generate a first response message according to the first request message, and send the first response message to the first ground network device. The first response message clearly indicates that the second ground network device agrees to synchronize the relevant information of the satellite message service. The first ground network device will start the synchronization process with the second ground network device according to the received first response message, and then the second ground network device receives the relevant information of the satellite message service sent from the first ground network device, and synchronizes the relevant information of the satellite message service with the first ground network device.

[0145] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (e.g., in response to a request from the second ground network device) send a first request message to the second ground network device. Here, the first request message may include one or more of user information corresponding to the terminal device (e.g., user code number, etc.), user subscription information (e.g., satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0146] In summary, according to the technical solution provided by the embodiment of the present disclosure, the present disclosure realizes the seamless connection of satellite message services between different networks through information synchronization between the first ground network device and the second ground network device. This helps to improve the user experience and enables users to maintain the continuity and consistency of messages in different network environments.

[0147] Furthermore, the above-mentioned cross-network message synchronization method also includes: sending a first notification message to the third satellite network device, where the first notification message is used to inform that the relevant information of the satellite message service has been successfully synchronized.

[0148] Specifically, after synchronization of relevant information of the satellite message service is achieved between the first ground network device and the second ground network device, the second ground network device will send a first notification message to the third satellite network device, informing the third satellite network device that relevant information of the satellite message service retained by the terminal device that has been transferred to communicate with the second ground network device has been synchronized to the second ground network device.

[0149] In summary, according to the technical solution provided by the embodiment of the present disclosure, by sending a first notification message to the third satellite network device, it can ensure that all relevant parties understand the synchronization status of the satellite message service related information, increase information transparency, and help reduce misunderstandings or conflicts caused by information asymmetry. And after receiving the notification of successful synchronization, the third satellite network device can adjust its resource allocation accordingly. For example, if the third satellite network device has previously reserved certain resources (such as storage space, processing power, etc.) for these terminal devices, then after confirming that the information has been synchronized to the second ground network device, these resources can be released for other purposes.

[0150] Further, performing an operation of synchronizing the satellite message service-related information with the first ground network device includes:

[0151] When no relevant information of the satellite messaging service is retained but the terminal device has subscribed to or has a subscription record for the satellite messaging service, a second request message is received from the first ground network device, and the second request message is used to request termination of relevant information of the synchronous satellite messaging service.

[0152] After the second request information is verified, a second response information is sent to the first ground network device to terminate the operation of the relevant information of the synchronous satellite message service. The second response information is used to indicate that the second ground network device agrees to terminate the relevant information of the synchronous satellite message service.

[0153] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, when it is found that the relevant information of the satellite message service of the terminal device is not retained but the terminal device has subscribed to or has subscribed to the satellite message service, the second ground network device will be informed of the discovery. At the same time, the first ground network device sends a second request message to the second ground network device, and the second request message is used to request the second ground network device to terminate the synchronization of relevant information of the satellite message service. After receiving the second request message, the second ground network device will parse and identify the second request message and verify the content of the second request message. When the verification is passed, a second response message will be generated and sent to the first ground network device. The second response message is used to indicate that the second ground network device agrees to terminate the relevant information of the synchronous satellite message service. Furthermore, the second ground network device stops any further operation on the synchronization of relevant information of the satellite message service with the first ground network device.

[0154] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (e.g., in response to a request from the second ground network device) send a second request message to the second ground network device. Here, the second request message may include one or more of user information corresponding to the terminal device (e.g., user code number, etc.), user subscription information (e.g., satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0155] In summary, according to the embodiments provided by the present invention, through the information interaction between the first ground network device and the second ground network device, the synchronization of satellite message service information that is no longer needed can be terminated in time, thereby avoiding the transmission of invalid data between networks, reducing the service problems that users may encounter due to inconsistent or erroneous information, and improving the user's service experience.

[0156] Further, performing the operation of synchronizing the satellite message service-related information with the first ground network device also includes:

[0157] A fifth request message is received from the third satellite network device, where the fifth request message is used to request relevant information of the synchronous satellite message service.

[0158] After the fifth request information is verified, a fifth response information is sent to the third satellite network device to synchronize the relevant information of the satellite message service with the first ground network device.

[0159] Further, after the fifth request information is verified, a fifth response information is sent to the third satellite network device to synchronize the relevant information of the satellite message service with the first ground network device, including:

[0160] After the fifth request information is verified, the fifth response information is sent to the third satellite network device; in response to the third satellite network device forwarding the fifth response message to the first ground network device after verifying the fifth response information, the second ground network device synchronizes the relevant information of the satellite message service with the first ground network device.

[0161] Specifically, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device, and according to the verification result, finds that the relevant information of the satellite message service of the terminal device is retained, and informs the third satellite network device of the discovery. At the same time, the first ground network device sends a fifth request message to the third satellite network device, and the fifth request message is used to request the second ground network device to synchronize the relevant information of the satellite message service retained in the first ground network device. After the third satellite network receives the fifth request message, after verifying the fifth request message, the fifth request message will be forwarded to the second ground network device. After receiving the fifth request message, the second ground network device will identify and parse the fifth request message, verify the content of the fifth request message, and when the verification is passed, it will generate a fifth response message and return the fifth response message to the third satellite network device. The fifth response message clearly indicates that the second ground network device agrees to synchronize the relevant information of the satellite message service. When the third satellite network device receives the fifth response message, it will verify the fifth response message, and after the verification is passed, it will send the fifth response message to the first ground network device. After receiving the fifth response information, the first ground network device starts a synchronization process with the second ground network device, and then synchronizes the satellite message service related information between the second ground network device and the first ground network device.

[0162] In summary, according to the technical solution provided by the present invention, cross-network satellite message service synchronization is achieved between the first ground network device and the second ground network device through the third satellite network device, ensuring that when users change network service providers, their satellite message services can be seamlessly connected to avoid service interruption.

[0163] Fig.10 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0164] like Fig.10 As shown, a cross-network message synchronization method can be executed by a third satellite network device, and the method specifically includes the following steps.

[0165] Step S1001, determining whether the terminal device communicating with the second ground network device retains relevant information of the satellite message service.

[0166] In the embodiment of the present disclosure, the terminal device initially communicates with the first ground network device. After the terminal device switches from the first ground network device to communicate with the second ground network device, the first ground network device verifies the user service corresponding to the terminal device to determine whether the terminal device retains the relevant information of the satellite message service, and informs the third satellite network device of the confirmed information.

[0167] In actual application scenarios, the terminal device initially communicates with the first ground network device. When the terminal device is ported to the second ground network device, the first ground network device verifies the user service corresponding to the terminal device to determine whether the terminal device retains the relevant information of the satellite messaging service. Here, "number portability" means that the user of the terminal device keeps the original mobile phone number unchanged, but changes the service provider (from the first ground network device to the second ground network device).

[0168] Here, satellite messages include but are not limited to existing Beidou short messages, Beidou short messages, Beidou short messages, Beidou satellite messages, satellite emergency messages, satellite emergency messages, satellite broadcast messages, Starlink messages, satellite Starlink messages, and satellite network short messages, short messages, MMS messages, and multimedia messages. Relevant information of satellite message services includes but is not limited to user information (such as user code numbers, etc.), user subscription information (such as satellite message service IDs subscribed by users, the number of retained satellite messages, etc.), satellite messages (such as message IDs, message contents, etc.), etc.

[0169] Step S1002, executing an operation of synchronizing satellite message service related information with the first ground network device.

[0170] In an embodiment of the present disclosure, after determining whether the terminal device communicating with the second ground network device retains the relevant information of the satellite message service, the first ground network device notifies the third satellite network device of the confirmation information. The third satellite network device evaluates whether it is necessary to synchronize the relevant information of the satellite message service with the first ground network device based on the confirmed information.

[0171] Here, the first ground network device and the second ground network device can be network devices that provide ground fixed communication network services and ground mobile network communication services for terminal devices, and can directly or indirectly receive satellite messages sent by terminal devices under ground network access; or directly or indirectly send satellite messages to terminal devices under ground network access; or can send satellite messages to third satellite network devices; or receive satellite messages sent by third satellite network devices; or directly or indirectly store satellite messages. The third satellite network device can be a satellite message network device located on the ground or on a satellite that is connected to the ground network, and can directly or indirectly receive satellite messages sent by terminal devices under satellite network access; or directly or indirectly send satellite messages to terminal devices under satellite network access; or send satellite messages to ground network devices (such as: the first ground network device, the second ground network device); or receive satellite messages sent by ground network devices (such as: the first ground network device, the second ground network device); or directly or indirectly store satellite messages. The third satellite network device includes but is not limited to the existing satellite network operation platform, Beidou civil short message communication operation service system, satellite network platform, Starlink network platform, etc.

[0172] In summary, according to the technical solution provided by the embodiment of the present disclosure, the first ground network device confirms whether the terminal device that communicates from the first ground network device to the second ground network device retains the relevant information of the satellite message service, and notifies the third satellite network device of the confirmed information. The third satellite network device evaluates whether it needs to synchronize the information with the first ground network device based on the confirmed information, thereby realizing the seamless transmission of satellite messages between different network devices. Even if the user transfers the number to another network, the satellite message can be synchronized to the new operator or related network device in a timely manner, thereby protecting the rights and interests and experience of the user.

[0173] Furthermore, the message synchronization method of the frame network mentioned above also includes: sending a second notification message to the second ground network device, and the second notification message is used to inform that the relevant information of the satellite message service has been successfully synchronized.

[0174] Specifically, after synchronization of relevant information of the satellite message service is achieved between the first ground network device and the third satellite network device, the third satellite network device will send a second notification message to the second ground network device to let the second ground network device know that relevant information of the satellite message service of the terminal device thereon that was once retained on the first ground network device has been synchronized to the third satellite network device.

[0175] In summary, according to the technical solution provided by the embodiment of the present disclosure, by sending the second notification message to the second satellite network device, it can ensure that all relevant parties understand the synchronization status of the satellite message service related information, increase information transparency, and help reduce misunderstandings or conflicts caused by information asymmetry. After receiving the notification of successful synchronization, the second ground network device can obtain satellite message service related information of the terminal device belonging to the second ground network device from the third satellite network. It helps to maintain data consistency between the second ground network device and the terminal device it manages.

[0176] Its resource allocation can be adjusted accordingly. For example, if the third satellite network device previously reserved certain resources (such as storage space, processing power, etc.) for these terminal devices, then after confirming that the information has been synchronized to the second ground network device, these resources can be released for other purposes.

[0177] Further, performing an operation of synchronizing the satellite message service-related information with the first ground network device includes:

[0178] In the case of retaining the relevant information of the satellite message service, receiving third request information from the first ground network device, the third request information being used to request the relevant information of the synchronous satellite message service;

[0179] After the third request information is verified, a third response information is sent to the first ground network device to synchronize the relevant information of the satellite message service with the first ground network device. The third response information is used to indicate that the third satellite network device agrees to synchronize the relevant information of the satellite message service.

[0180] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, it is found that the relevant information of the satellite message service of the terminal device is retained, and the third satellite network device is notified of the discovery. At the same time, the first ground network device sends a third request message to the third satellite network device, and the third request message is used to request the third satellite network device to synchronize the relevant information of the satellite message service retained in the first ground network device. After receiving the third request message, the third satellite network device will identify and parse the third request message, verify the content of the third request message, and when the verification is passed, it will generate a third response message according to the third request message, and send the third response message to the first ground network device. The third response message clearly indicates that the third satellite network device agrees to synchronize the relevant information of the satellite message service. Next, the first ground network device will start the synchronization process with the third satellite network device according to the received third response message. Then, the relevant information of the satellite message service is synchronized between the first ground network device and the third satellite network device.

[0181] Exemplarily, in order to achieve cross-network message synchronization, the first ground network device may actively or passively (e.g., in response to a request from the third satellite network device) send a third request message to the third satellite network device. Here, the third request message may include one or more of user information corresponding to the terminal device (e.g., user code number, etc.), user subscription information (e.g., satellite message service ID subscribed by the user, number of retained satellite messages, etc.), and carrier information.

[0182] In summary, according to the technical solution provided by the embodiment of the present disclosure, the present disclosure synchronizes information between the first ground network device and the third satellite network device, and when the terminal device switches to communicate with the second ground network device, the second ground network device can obtain the relevant information of the satellite message service of the terminal device through the third satellite network device, thereby realizing the seamless connection of the satellite message service between different networks. This helps to improve the user experience and enables users to maintain the continuity and consistency of messages in different network environments.

[0183] Furthermore, the above-mentioned cross-network message synchronization method also includes: forwarding third request information to the second ground network device for identity authentication of the terminal device.

[0184] Specifically, the third satellite network device forwards the third request information to the second ground network device before synchronizing the relevant information of the satellite message service. After receiving the third request information, the second ground network device verifies the content of the third request information, such as: performing user information verification to confirm whether the user corresponding to the terminal device has ported the number to the second ground network device. Checking whether the satellite message service ID subscribed by the user exists, confirming whether the user corresponding to the terminal device has subscribed to the relevant service. Confirming whether the user corresponding to the terminal device has completed the porting process and has become a user of the second ground network device.

[0185] Further, performing the operation of synchronizing the satellite message service-related information with the first ground network device also includes:

[0186] In a case where no relevant information of the satellite messaging service is retained but the terminal device has subscribed to or has a subscription record for the satellite messaging service, receiving fourth request information from the first ground network device, the fourth request information being used to request termination of relevant information of the synchronous satellite messaging service;

[0187] After the fourth request information is verified, a fourth response information is sent to the first ground network device to terminate the operation of the relevant information of the synchronous satellite message service. The fourth response information is used to indicate that the third satellite network device agrees to terminate the relevant information of the synchronous satellite message service.

[0188] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, when it is found that the relevant information of the satellite message service of the terminal device is not retained but the terminal device has subscribed to or has subscribed to the satellite message service, the discovery will be notified to the third satellite network device. At the same time, the first ground network device sends a fourth request message to the third satellite network device, and the fourth request message is used to request the third satellite network device to terminate the synchronization of relevant information of the satellite message service. After receiving the fourth request message, the third satellite network device will parse and identify the fourth request message and verify the content of the fourth request message. When the verification is passed, the fourth response message will be generated and sent to the first ground network device. The fourth response message is used to indicate that the third satellite network device agrees to terminate the relevant information of the synchronous satellite message service. The first ground network device will end the synchronization process with the third satellite network device according to the received fourth response message.

[0189] Furthermore, the message synchronization method of the frame network mentioned above also includes: forwarding fourth request information to the second ground network device for identity authentication of the terminal device.

[0190] Specifically, the third satellite network device forwards the fourth request information to the second ground network device before synchronizing the relevant information of the satellite message service. After receiving the third request information, the second ground network device verifies the content of the fourth request information, such as: performing user information verification to confirm whether the user corresponding to the terminal device has ported the number to the second ground network device. Checking whether the satellite message service ID subscribed by the user exists, confirming whether the user corresponding to the terminal device has subscribed to the relevant service. Confirming whether the user corresponding to the terminal device has completed the porting process and has become a user of the second ground network device.

[0191] Fig.11 The invention further illustrates the cross-network message synchronization method according to an embodiment of the present disclosure.

[0192] like Fig.11 As shown, a cross-network message synchronization method can be executed by a third satellite network device, and the method specifically includes the following steps.

[0193] Step S1101, determining whether the terminal device communicating with the second ground network device retains the relevant information of the satellite message service;

[0194] Step S1102, executing an operation of synchronizing the second ground network device with the first ground network device about the relevant information of the satellite message service.

[0195] In the embodiment of the present disclosure, the terminal device initially communicates with the first ground network device. After the terminal device switches from the first ground network device to the second ground network device for communication, the first ground network device verifies the user service corresponding to the terminal device to determine whether the terminal device retains the relevant information of the satellite message service. The confirmation information is notified to the third satellite network device. The third satellite network device evaluates whether it is necessary to synchronize the relevant information of the satellite message service between the second network device and the first ground network device based on the confirmed information. That is, whether it is necessary to synchronize the relevant information of the satellite message service between the second network device and the first ground network device through the third satellite network device.

[0196] In actual application scenarios, the terminal device initially communicates with the first ground network device. When the terminal device is ported to the second ground network device, the first ground network device verifies the user service corresponding to the terminal device to determine whether the terminal device retains the relevant information of the satellite messaging service. Here, "number portability" means that the user of the terminal device keeps the original mobile phone number unchanged, but changes the service provider (from the first ground network device to the second ground network device).

[0197] Here, satellite messages include but are not limited to existing Beidou short messages, Beidou short messages, Beidou short messages, Beidou satellite messages, satellite emergency messages, satellite emergency messages, satellite broadcast messages, Starlink messages, satellite Starlink messages, and satellite network short messages, short messages, MMS messages, and multimedia messages. Relevant information of satellite message services includes but is not limited to user information (such as user code numbers, etc.), user subscription information (such as satellite message service IDs subscribed by users, the number of retained satellite messages, etc.), satellite messages (such as message IDs, message contents, etc.), etc.

[0198] Here, the first ground network device and the second ground network device can be network devices that provide ground fixed communication network services and ground mobile network communication services for terminal devices, and can directly or indirectly receive satellite messages sent by terminal devices under ground network access; or directly or indirectly send satellite messages to terminal devices under ground network access; or can send satellite messages to third satellite network devices; or receive satellite messages sent by third satellite network devices; or directly or indirectly store satellite messages. The third satellite network device can be a satellite message network device located on the ground or on a satellite that is connected to the ground network, and can directly or indirectly receive satellite messages sent by terminal devices under satellite network access; or directly or indirectly send satellite messages to terminal devices under satellite network access; or send satellite messages to ground network devices (such as: the first ground network device, the second ground network device); or receive satellite messages sent by ground network devices (such as: the first ground network device, the second ground network device); or directly or indirectly store satellite messages. The third satellite network device includes but is not limited to the existing satellite network operation platform, Beidou civil short message communication operation service system, satellite network platform, Starlink network platform, etc.

[0199] In summary, according to the technical solution provided by the embodiment of the present disclosure, the first ground network device confirms whether the terminal device that communicates from the first ground network device to the second ground network device retains the relevant information of the satellite message service, and notifies the third satellite network device of the confirmed information. The third satellite network device evaluates whether it is necessary to synchronize the second ground network device with the first ground network device through the third satellite network device based on the confirmed information, thereby realizing the seamless transmission of satellite messages between different network devices. Even if the user transfers the number to another network, the satellite message can be synchronized to the new operator or related network device in a timely manner, thereby protecting the rights and interests and experience of the user.

[0200] Further, the operation of synchronizing the second ground network device with the first ground network device about the relevant information of the satellite message service includes:

[0201] receiving fifth request information from the first ground network device, where the fifth request information is used to request relevant information of the synchronous satellite message service;

[0202] After verifying the fifth request information, sending the fifth request information to the second ground network device;

[0203] receiving fifth response information sent by the second ground network device after verifying the fifth request information, wherein the fifth response information is used to indicate that the second ground network device agrees to synchronize relevant information of the satellite message service;

[0204] After verifying the fifth response information, the fifth response information is sent to the first ground network device, so that the second ground network device synchronizes the relevant information of the satellite message service with the first ground network device.

[0205] In an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, it is found that the relevant information of the satellite message service of the terminal device is retained, and the third satellite network device is notified of the discovery. At the same time, the first ground network device sends a fifth request message to the third satellite network device, and the fifth request message is used to request the second ground network device to synchronize the relevant information of the satellite message service retained in the first ground network device. After the third satellite network receives the fifth request message, after verifying the fifth request message, the fifth request message will be forwarded to the second ground network device. After receiving the fifth request message, the second ground network device will identify and parse the fifth request message, verify the content of the fifth request message, and when the verification is passed, it will generate a fifth response message and return the fifth response message to the third satellite network device. The fifth response message clearly indicates that the second ground network device agrees to synchronize the relevant information of the satellite message service. When the third satellite network device receives the fifth response message, it will verify the fifth response message, and after the verification is passed, it will send the fifth response message to the first ground network device. After receiving the fifth response information, the first ground network device starts a synchronization process with the second ground network device, and then synchronizes the satellite message service related information between the second ground network device and the first ground network device.

[0206] In summary, according to the technical solution provided by the present invention, the first ground network device and the second ground network device realize cross-network satellite message service synchronization through the third satellite network device, ensuring that when the user changes the network service provider, their satellite message service can be seamlessly connected to avoid service interruption.

[0207] Further, the operation of performing synchronization of the second ground network device with the first ground network device with the relevant information of the satellite message service also includes:

[0208] In the case where no relevant information of the satellite messaging service is retained but the terminal device has subscribed to or has a subscription record for the satellite messaging service, receiving sixth request information from the first ground network device, the sixth request information being used to request termination of relevant information of the synchronous satellite messaging service;

[0209] After the sixth request information is verified, a sixth response information is sent to the first ground network device, and the sixth response information is used to indicate that the third network device agrees to terminate the relevant information of the synchronous satellite message service.

[0210] Further, after the sixth request information is verified, before sending the sixth response information to the first ground network device, the method further includes:

[0211] Forward the sixth request information to the second ground network device for authenticating the terminal device.

[0212] In an embodiment of the present disclosure, in an embodiment of the present disclosure, the first ground network device performs user service verification on the terminal device that has been transferred to communicate with the second ground network device. According to the verification result, when it is found that the relevant information of the satellite message service of the terminal device is not retained but the terminal device has subscribed to or has subscribed to the satellite message service, the third satellite network device will be informed of the discovery. At the same time, the first ground network device sends a sixth request message to the third satellite network device, and the sixth request message is used to request the second ground network device to terminate the synchronization of relevant information of the satellite message service. After receiving the sixth request message, the third satellite network device will parse and identify the sixth request message, and verify the content of the sixth request message. When the verification is passed, the sixth response message will be generated and sent to the first ground network device. The sixth response message is used to indicate that the third satellite network device agrees to terminate the relevant information of the synchronous satellite message service. The first ground network device will end the synchronization process with the second ground network device according to the received sixth response message. Then, the first ground network device and the second ground network device are stopped from synchronizing the relevant information of the satellite message service through the third satellite network device.

[0213] In summary, according to the technical solution provided by the embodiments of the present invention, the terminal device of the present invention migrates between different ground network devices while maintaining the continuity or timely termination of its satellite message service, which reflects the flexibility of service provision and enhances user satisfaction and trust in the service.
