Description

A communication method, electronic device and system

[0001] This application claims priority to Chinese Patent Application No. 202410572396.0, filed on May 9, 2024, with the Chinese National Intellectual Property Administration, entitled "A Communication Method, Electronic Device and System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication technology, and more particularly to a communication method, electronic device, and system. Background Technology

[0003] With the development of technology, users are no longer limited to using terrestrial networks for communication; they can also use satellite networks to make phone calls, send text messages, and perform other communication activities.

[0004] Currently, satellite networks are generally deployed in two ways. One is to deploy the satellite network independently of the terrestrial cellular network, and the other is to deploy the satellite network as a roaming network for the terrestrial cellular network. If the satellite network is deployed independently of the terrestrial cellular network, a separate subscriber identity module (SIM) card is required, which means a separate billing method. In this case, users need to subscribe to a satellite data plan, and if they want to use the terrestrial cellular network, they also need to activate roaming services for that network, resulting in additional costs. If the satellite network is deployed as a roaming network for the terrestrial cellular network, it uses a terrestrial cellular SIM card. In this case, users in environments without a terrestrial network cannot easily activate roaming services from the terrestrial cellular network to the satellite network. For users who want to use satellite networks for communication, both deployment methods are extremely inconvenient. Summary of the Invention

[0133] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be a limitation of this application.

[0134] With the development of technology, users are no longer limited to using terrestrial networks for communication; they can also use satellite networks to make phone calls, send text messages, and perform other communication activities.

[0135] Currently, satellite networks are generally deployed in two ways. One is to deploy the satellite network independently of the terrestrial cellular network, and the other is to deploy the satellite network as a roaming network for the terrestrial cellular network. If the satellite network is deployed independently of the terrestrial cellular network, a separate subscriber identity module (SIM) card is required, which means a separate billing method. In this case, users need to subscribe to a satellite data plan, and if they want to use the terrestrial cellular network, they also need to activate roaming services for that network, resulting in additional costs. If the satellite network is deployed as a roaming network for the terrestrial cellular network, it uses a terrestrial cellular SIM card. In this case, users in environments without a terrestrial network cannot easily activate roaming services from the terrestrial cellular network to the satellite network. For users who want to use satellite networks for communication, both deployment methods are extremely inconvenient.

[0136] Currently, communication services can be activated using SIM card technology. Electronic devices can have an initial security context pre-installed when the SIM card is issued, and the operator's key pre-installed when the operator activates the plan. However, activating a plan using SIM card technology requires a network connection. For example, roaming between a satellite network and a terrestrial cellular network requires prior activation of a roaming plan, which also involves roaming fees and the possibility of changing phone numbers. Similarly, roaming between a terrestrial cellular network and a satellite network requires prior activation of a roaming plan within the terrestrial cellular network environment, meaning there are fixed plan costs regardless of whether the user uses the satellite network. Alternatively, communication services can be activated using an embedded subscriber identity module (eSIM) technology. Users need to pre-order an eSIM plan in a network environment. After ordering the eSIM plan, a quick response (QR) code is generated, which the user can scan to activate the eSIM. Therefore, eSIM service activation depends on the network environment; users cannot order plans or activate eSIMs without a network connection. Emergency bearer technology can also be used to activate communication services. However, in environments without network connectivity, the current emergency bearer only provides emergency call functionality and cannot use data services, thus preventing connection to other networks. Additionally, communication services can be activated via Wi-Fi CAPTCHA login. However, Wi-Fi CAPTCHA login relies on terrestrial cellular networks to transmit the CAPTCHA, making authentication impossible for users without a network connection.

[0137] As can be seen from the existing solutions described above, current technical solutions for enabling communication services all rely on a network environment. For terrestrial users in environments without a network, access to the terrestrial network is impossible, thus preventing the activation of satellite communication services. Furthermore, the number of SIM card slots in terminal devices is limited. As the number of operators increases, the use of physical SIM cards will affect the proportion of users activating service plans.

[0138] To address the aforementioned issues, this application provides a communication method, electronic device, and system. This method can be applied to a satellite communication system including a first terminal device and a first network device. Implementing this method, the first terminal device can send a request to the first network device to access the public internet. This request indicates whether the first terminal device has configured satellite communication services. If the first terminal device has not configured satellite communication services, it can establish a dedicated bearer with the first network device. The first terminal device can then send a satellite communication service activation request to the first network device based on this dedicated bearer. In response to this request, the first network device can grant the first terminal device permission to access the public internet. The first network device can then return a notification of successful satellite communication service activation to the first terminal device. After receiving this notification, the first terminal device can access the public internet. Thus, the first terminal device can activate satellite communication services even in a network-free environment, improving the user experience.

[0139] In some embodiments, this method can be implemented based on eSIM technology. An eSIM can contain a base key and a carrier key. The base key is pre-installed by the eSIM manufacturer in the embedded secure element (eSE) at the factory, while the carrier key is downloaded over the air when the user uses the eSIM. If a user already has an eSIM with a terrestrial operator, they can use the eSIM to download and install a profile online, enabling internet access without a physical SIM card. Implementing a communication method using eSIM technology can reduce the usage of SIM card slots on terminal devices, facilitate users activating data plans, and improve the user experience.

[0140] In some embodiments, the first terminal device may include a satellite communication profile, which may contain authentication information, including user A's identity information and a key. When the first terminal device includes a satellite communication profile, a request sent by the first terminal device to the first network device to access the public internet may include the aforementioned authentication information. The first network device can determine whether the first terminal device has configured satellite communication services through the authentication information in the satellite communication profile.

[0141] In some embodiments, if the first terminal device does not contain a satellite communication profile, the first terminal device may download the satellite communication profile from the first network device.

[0142] In some embodiments, a satellite communication service activation request may include user A's identity information and the satellite communication service package selected by user A from the menu bar of the satellite communication service packages.

[0143] In some embodiments, after receiving a notification from the first network device that the satellite communication service has been successfully activated, the first terminal device can activate user A's key and access the public Internet based on the activated key.

[0144] In this embodiment of the application, granting the first terminal device the permission to access the public Internet by the first network device specifically means granting the first terminal device the permission to send and receive data packets on the public Internet.

[0145] In this embodiment of the application, the first network device may include a first server, which may be a satellite communication service activation server.

[0146] After satellite communication services are launched, and with the satellite network deployed independently of the terrestrial cellular network, the satellite communication operator is a new operator using a new eSIM card and number. When users use satellite communication services such as making calls and sending text messages, the receiving users find it difficult to adapt, resulting in a poor user experience.

[0147] This application provides another communication method, electronic device, and system. This method can be applied to a communication system including a first terminal device and a satellite network device. Implementing the above method, the first terminal device can send calling signaling A to the satellite network device. Calling signaling A includes a calling number and a called number; wherein the calling number is user A's satellite number, and the called number is user B's number; the satellite network device can determine user A's cellular number from database A based on user A's satellite number, and database A includes user A's satellite number and cellular number; the satellite network device can send calling signaling B to user B's second terminal device. The calling number in calling signaling B is user A's cellular number, and the called number in calling signaling B is user B's number; after receiving calling signaling B, the second terminal device can display the calling number (i.e., user A's cellular number) in calling signaling B. In this way, after the satellite communication service is activated, when the first terminal device (caller) calls another number of the second terminal device (called party) using the satellite number, the second terminal device (called party) can display the caller's cellular number, keeping the cellular number received by the called party consistent with the satellite number, thus improving the user experience of the called party.

[0148] In some embodiments, the called number in the calling signaling A may belong to a satellite communication operator or a cellular communication operator.

[0149] In some embodiments, database A may be located on a core network element of a communication system that includes a first terminal device and a satellite network device.

[0150] First, we will introduce a communication system 10 and related equipment provided in the embodiments of this application.

[0151] Figure 1 illustrates an exemplary communication system 10 provided in an embodiment of this application.

[0152] As shown in Figure 1, the communication system 10 may include: terminal equipment 100, satellite 21, satellite network equipment 200, terminal equipment 300, and cellular network equipment 400. Satellite network equipment 200 may include gateway station 22 and satellite core network 23. Cellular network equipment 400 may include base station 41, cellular access network 42, cellular core network 43, base station 44, cellular access network 45, and cellular core network 46. Terminal equipment 100 is also referred to as a first terminal equipment, satellite network equipment 200 as a first network equipment, and terminal equipment 300 as a second terminal equipment.

[0153] In communication system 10, terminal device 100 can establish a communication connection with satellite 21, satellite 21 can establish a communication connection with satellite network device 200, that is, satellite 21 can establish a communication connection with gateway station 22, and gateway station 22 can establish a communication connection with satellite core network 23. Satellite network device 200 can establish a communication connection with cellular network device 400, and cellular network device 400 can establish a communication connection with terminal device 300.

[0154] In some embodiments, terminal device 100 may send a request to access the public internet to satellite 21. Satellite 21 may send the request to gateway station 22, which may then send the request to satellite core network 23. This request to access the public internet may be used to indicate whether terminal device 100 is configured with satellite communication services. In some embodiments, terminal device 100 may include a satellite communication profile, which may include authentication information, including user A's identity information and key. In response to the request to access the public internet, which may include the aforementioned authentication information, if terminal device 100 includes a satellite communication profile, satellite core network 23 can determine whether terminal device 100 is configured with satellite communication services using the authentication information in the satellite communication profile. If it is determined that terminal device 100 is not configured with satellite communication services, satellite core network 23 may establish a dedicated bearer with terminal device 100. In some embodiments, the communication system 10 may also include a server (not shown in FIG. 1). In this embodiment, the server may refer to a satellite communication service activation server. Terminal device 100 can send a satellite communication service activation request to the server via a dedicated bearer. This request includes user A's identity information and the server's address information. In response to the request, the server can grant terminal device 100 access to the public internet and send a notification of successful activation. Upon receiving this notification, terminal device 100 can activate user A's key and access the public internet using the activated key.

[0155] When terminal device 100 needs to communicate with terminal device 300, terminal device 100 can send communication data (such as paging messages, target information, call data, etc.) to satellite 21. The communication data may carry the device identifier of terminal device 300. The device identifier can be used to identify the device, such as the eSIM card number of the device. Satellite 21 can send the communication data to satellite network device 200, which can then send it to cellular network device 400, which in turn sends the communication data to terminal device 300.

[0156] In this way, based on satellite 21, satellite network equipment 200 and cellular network equipment 400, terminal equipment 100 and terminal equipment 300 can communicate with each other.

[0157] In other embodiments, after the satellite communication service is activated, terminal device 100 can send calling signaling A to satellite 21. Calling signaling A includes a calling number and a called number, where the calling number is user A's satellite number and the called number is user B's number. Satellite 21 can send calling signaling A to gateway station 22, which can then send it to satellite core network 23. Satellite core network 23 can determine user A's cellular number from database A based on user A's satellite number. Database A includes user A's satellite number and cellular number. Satellite core network 23 can send calling signaling B to the cellular core network 46 accessed by user B's terminal device 300. Calling signaling B contains user A's cellular number and user B's number as both the calling and called numbers. Cellular core network 46 can send calling signaling B to cellular access network 45, which in turn sends calling signaling B to base station 44. Base station 44 then forwards calling signaling B to terminal device 300. After receiving calling signaling B, terminal device 300 can display the calling number (i.e., user A's cellular number) in calling signaling B.

[0158] It is understood that the communication system 10 shown in Figure 1 is just an example. In some embodiments, the communication system 10 may include more electronic devices or more base stations, etc., which is not limited here.

These different processing units may be independent devices or integrated into one or more processors.

[0163] In some embodiments, the terminal device 100 may also include one or more processors 110.

[0164] The controller can serve as the nerve center and command center of an electronic device. Based on the instruction opcode and timing signals, the controller generates operation control signals to control the fetching and execution of instructions.

[0165] The processor 110 may also include a memory for storing instructions and data.

[0166] USB port 130 is a USB standard compliant interface, specifically a Mini USB port, Micro USB port, or USB Type-C port. USB port 130 can be used to connect a charger to charge terminal device 100, and can also be used for data transfer between terminal device 100 and peripheral devices. It can also be used to connect headphones for audio playback. This interface can also be used to connect other electronic devices, such as AR devices.

[0167] The charging management module 140 receives charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 receives charging input from the wired charger via the USB interface 130. In some wireless charging embodiments, the charging management module 140 receives wireless charging input via the wireless charging coil of the terminal device 100. While charging the battery 142, the charging management module 140 can also supply power to the terminal device 100 via the power management module 141.

[0168] The power management module 141 connects the battery 142, the charging management module 140, and the processor 110. The power management module 141 receives input from the battery 142 and / or the charging management module 140, providing power to the processor 110, internal memory 121, external memory, display screen 194, camera 193, and wireless communication module 160, etc. The power management module 141 can also be used to detect parameters such as battery capacity, battery cycle count, and battery health status (leakage current, impedance). In some other embodiments, the power management module 141 may also be located within the processor 110. In other embodiments, the power management module 141 and the charging management module 140 may be located in the same device.

[0169] The wireless communication function of the terminal device 100 can be implemented through antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, modem processor and baseband processor, etc.

[0170] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in terminal device 100 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with a tuning switch.

[0171] The mobile communication module 150 can provide solutions for wireless communication, including 2G / 3G / 4G / 5G, applied to the terminal device 100. The mobile communication module 150 may include at least one filter, switch, power amplifier, low-noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves via the antenna 1, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to the modem processor for demodulation. The mobile communication module 150 can also amplify the signal modulated by the modem processor and convert it into electromagnetic waves for radiation via the antenna. In some embodiments, at least some functional modules of the mobile communication module 150 may be housed in the processor 110. In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0172] The modem processor may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs a sound signal through an audio device or displays an image or video through the display screen 194. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 110 and may be housed in the same device as the mobile communication module 150 or other functional modules.

[0173] The wireless communication module 160 can provide solutions for wireless communication applications on the terminal device 100, including WLAN (such as Wi-Fi networks), Bluetooth, Global Navigation Satellite System (GNSS), Frequency Modulation (FM), NFC, Infrared (IR), and Ultra Wideband (UWB). The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via an antenna, modulates and filters the electromagnetic wave signals, and sends the processed signal to the processor 110. The wireless communication module 160 can also receive signals to be transmitted from the processor 110, modulate and amplify them, and then convert them into electromagnetic waves for radiation via the antenna. Exemplarily, the wireless communication module 160 may include a Bluetooth module, a Wi-Fi module, etc. In some embodiments, a portion of the antenna of the terminal device 100 is coupled to the mobile communication module 150, and another portion of the antenna is coupled to the wireless communication module 160, enabling the terminal device 100 to communicate with networks and other devices via wireless communication technology.

[0174] In this embodiment, terminal device 100 can send a request to access the public internet to satellite 21 via wireless communication module 160. Satellite 21 can then forward the request to gateway station 22, which in turn can forward it to satellite core network 23. This request can be used to indicate whether terminal device 100 has configured satellite communication services. In some embodiments, terminal device 100 may include a satellite communication profile, which may contain authentication information, including user A's identity information and key. In response to the request to access the public internet, which may include the aforementioned authentication information, if terminal device 100 includes a satellite communication profile, satellite core network 23 can determine whether terminal device 100 has configured satellite communication services using the authentication information in the profile. If it is determined that terminal device 100 has not configured satellite communication services, satellite core network 23 can establish a dedicated bearer with terminal device 100. Terminal device 100 can send a satellite communication service activation request to the satellite communication service activation server via wireless communication module 160 based on a dedicated bearer. This request includes user A's identity information and the server's address information. In response to the satellite communication service activation request, the server can grant terminal device 100 access to the public internet and return a notification of successful activation. Upon receiving this notification, terminal device 100 can activate user A's key and access the public internet via wireless communication module 160 using the activated key.

[0175] In this embodiment, when terminal device 100 needs to communicate with terminal device 300, terminal device 100 can send communication data (such as paging messages, target information, call data, etc.) to satellite 21 through wireless communication module 160. The communication data may carry the device identifier of terminal device 300. The device identifier can be used to identify the device, such as the eSIM card number of the device. Satellite 21 can send the communication data to satellite network device 200, which can then send it to cellular network device 400, which in turn sends the communication data to the wireless communication module of terminal device 300.

[0176] In this embodiment, after the satellite communication service is activated, the terminal device 100 can send calling signaling A to the satellite 21 via the wireless communication module 160. Calling signaling A includes a calling number and a called number, where the calling number is user A's satellite number and the called number is user B's number. The satellite 21 can send calling signaling A to the gateway station 22, which in turn can send it to the satellite core network 23. The satellite core network 23 can determine user A's cellular number from database A based on user A's satellite number. Database A includes user A's satellite number and cellular number. The satellite core network 23 can then send calling signaling B to the cellular core network 46 accessed by user B's terminal device 300. Calling signaling B contains user A's cellular number and user B's number as both the calling and called numbers. Cellular core network 46 can send calling signaling B to cellular access network 45, which in turn sends calling signaling B to base station 44. Base station 44 then forwards calling signaling B to the wireless communication module of terminal device 300. After receiving calling signaling B, terminal device 300 can display the calling number (i.e., user A's cellular number) from calling signaling B on its display screen.

[0177] Terminal device 100 can implement display functions, such as displaying aggregated messages based on the same event, through a GPU, display screen 194, and application processor. The GPU is a microprocessor for image processing, connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 110 may include one or more GPUs, which execute instructions to generate or modify display information.

[0179] Terminal device 100 can perform shooting functions through an ISP, camera 193, video codec, GPU, display 194, and application processor. The ISP processes data fed back from the camera 193. The camera 193 captures still images or videos. The digital signal processor processes digital signals, including digital image signals and other digital signals. The video codec compresses or decompresses digital video. Terminal device 100 can support one or more video codecs. The NPU (Neural-Network Processing Unit) is a neural network (NN) computing processor that, by borrowing from the structure of biological neural networks, such as the transmission patterns between neurons in the human brain, rapidly processes input information and can continuously learn itself.

[0180] The external storage interface 120 can be used to connect an external storage card, such as a Micro SD card, to expand the storage capacity of the terminal device 100. The external storage card communicates with the processor 110 through the external storage interface 120 to perform data storage functions. For example, music, photos, videos, and other data can be stored on the external storage card.

[0181] The internal memory 121 can be used to store one or more computer programs, which include instructions. The processor 110 can execute the instructions stored in the internal memory 121, thereby causing the terminal device 100 to perform the message processing methods provided in some embodiments of this application, as well as various functional applications and data processing. The internal memory 121 may include a stored program area and a stored data area. The stored program area may store the operating system; it may also store one or more applications (such as a gallery, contacts, etc.). The stored data area may store data created during the use of the terminal device 100 (such as photos, contacts, etc.). Furthermore, the internal memory 121 may include high-speed random access memory (RAM) and may also include non-volatile memory (NVM), such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc.

[0182] The SIM card interface 195 is used to connect a SIM card. The SIM card can be inserted into or removed from the SIM card interface 195 to make contact with and separate from the terminal device 100.

[0201] (I) Example 1

[0202] In some embodiments, terminal device 100 may send a request to satellite network device 200 to access the public Internet. This request indicates whether the first terminal device has configured satellite communication services. If the first terminal device has not configured satellite communication services, terminal device 100 may establish a dedicated bearer with satellite network device 200. Terminal device 100 may then send a satellite communication service activation request to satellite network device 200 based on this dedicated bearer. In response to this request, satellite network device 200 may grant terminal device 100 permission to access the public Internet (i.e., permission to send and receive data packets on the public Internet). Satellite network device 200 may return a notification of successful satellite communication service activation to terminal device 100. After receiving this notification, terminal device 100 can access the public Internet. In this way, terminal device 100 can activate satellite communication services even in a network-free environment, improving user experience.

[0203] The following is a flowchart illustrating a notification method provided in an embodiment of this application.

[0204] Figure 3 illustrates, exemplarily, the specific flow of a notification method provided in an embodiment of this application. This method can be applied to a satellite communication system including a terminal device 100 and a satellite network device 200. The satellite network device 200 may include a satellite core network 23 and a server.

[0205] As shown in Figure 3, the method may include:

[0206] S101, Terminal device 100 sends a request to the satellite core network 23 to access the public Internet.

[0207] Specifically, after initiating random access, terminal device 100 can send a request to the satellite core network 23 to access the public internet. If terminal device 100 contains a satellite communication profile, this request to access the public internet can include the authentication information of the satellite communication profile, which may include user A's identity information and key. The public internet refers to a globally accessible internet network that can be used by the public. Terminal device 100 can obtain access to the public internet by sending a request to satellite network device 200.

[0208] In some embodiments, before sending a request to access the public Internet to the satellite core network 23, the terminal device 100 may display a user interface 710 as shown in FIG7A. The user interface 710 may include a control for activating satellite communication services (such as control 711), and the terminal device 100 may detect the operation of clicking the control for activating satellite communication services (such as control 711).

[0209] In other embodiments, terminal device 100 may display a user interface 720 as shown in FIG7B, which may include one or more options (such as option 722, option "No"). Upon detecting a click on option 722, terminal device 100 may send a request to the satellite core network 23 to access the public internet. Upon detecting a click on option "No", terminal device 100 may not send a request to the satellite core network 23 to access the public internet.

[0210] In other embodiments, terminal device 100 may display a user interface 730 as shown in FIG7C, which may include option 731. Upon detecting a click on option 731, terminal device 100 may send a request to the satellite core network 23 to access the public Internet.

[0211] S102, Satellite Core Network 23 determines whether Terminal Equipment 100 is configured with satellite communication services.

[0212] Specifically, the request to access the public internet is used to indicate whether the first terminal device is configured with satellite communication services.

[0213] In some embodiments, in response to a request from terminal device 100 to access the public internet, if terminal device 100 includes a satellite communication profile, the request may include authentication information of the satellite communication profile. Satellite core network 23 can determine whether terminal device 100 has configured satellite communication services through the authentication information in the satellite communication profile. The authentication information in the satellite communication profile may include user A's identity information and key.

[0214] Understandably, step S102 can use the instrument detection log process and appropriate staking to obtain evidence.

[0215] S103, terminal equipment 100 and satellite core network 23 establish a dedicated bearer.

[0216] In some embodiments, when the terminal device 100 does not contain a satellite communication profile, the request for access to the public internet sent by the terminal device 100 to the satellite core network 23 does not include authentication information for the satellite communication profile. After receiving the request for access to the public internet from the terminal device 100, the satellite core network 23 can establish a dedicated bearer with the terminal device 100. The terminal device 100 can then download the satellite communication profile from the satellite core network 23 based on the dedicated bearer.

[0217] In other embodiments, if the terminal device 100 includes a satellite communication profile, and the satellite core network 23 determines that the terminal device 100 is not configured with satellite communication services through the authentication information of the satellite communication profile in the request to access the public Internet, then the satellite core network 23 can establish a dedicated bearer with the terminal device 100.

[0218] In some embodiments, if the satellite core network 23 determines, through the authentication information of the satellite communication profile in the request to access the public Internet, that the terminal device 100 is not configured with satellite communication services (i.e., the key of user A in the satellite communication profile is not activated), the satellite core network 23 may return an authentication failure notification to the terminal device 100. After receiving the authentication failure notification, the terminal device 100 may restrict the user A's dwell state and provide emergency call services to user A.

[0219] In some embodiments, after restricting the dwell status of user A, terminal device 100 may send a dedicated bearer establishment request to the access and mobility management function (AMF) in satellite network device 200. This dedicated bearer establishment request may include an SM PDU DN request container field, which contains a Network Access Identifier (NAI) field. The NAI field may contain user identity information such as International Mobile Subscriber Identity (IMSI) information and operator information such as Public Land Mobile Network (PLMN) information. In this embodiment, the NAI field can be used to identify the type of dedicated bearer.

[0220] In some embodiments, after receiving a dedicated bearer establishment request sent by terminal device 100, the AMF can verify the dedicated bearer establishment request to determine whether to configure a dedicated bearer for terminal device 100. If the AMF determines to configure a dedicated bearer for terminal device 100, it forwards the dedicated bearer establishment request to the user plane function (UPF).

[0221] In some embodiments, after receiving a dedicated bearer establishment request forwarded by the AMF, the UPF can configure the bearer resources and Internet Protocol (IP) address of the dedicated bearer for the terminal device 100 according to the type of dedicated bearer in the dedicated bearer establishment request. After configuring the bearer resources and IP address of the dedicated bearer for the terminal device 100, the UPF can establish a dedicated bearer with the terminal device 100. After establishing a dedicated bearer with the terminal device 100, the UPF can return a dedicated bearer establishment completion response to the terminal device 100.

[0222] In some embodiments, the dedicated bearer is configured with a unique name, and the satellite core network 23 can distinguish the type of the dedicated bearer by the unique name of the dedicated bearer.

[0223] In some embodiments, the dedicated bearer can provide targeted (i.e., fixed destination address) packet forwarding services based on packet format, destination IP address, and port number. For example, the dedicated bearer can be used by terminal device 100 to send a satellite communication service activation request to a satellite communication service activation server.

[0224] S104. Terminal device 100 sends a satellite communication service activation request to the server.

[0225] Specifically, terminal device 100 can send a satellite communication service activation request to a server (e.g., a satellite communication service activation server) based on a dedicated bearer. This dedicated bearer can be a UPF bearer, and the satellite communication service activation request can include user A's identity information, with the destination address of the request being the aforementioned server. It is understood that the server can belong to satellite network device 200 or to the public internet; this embodiment does not impose such limitations.

[0226] In some embodiments, the satellite communication service activation request may also include the satellite communication service package and billing information selected by user A from the menu bar of the satellite communication service package.

[0227] In some embodiments, before sending a satellite communication service activation request to a server (e.g., a satellite communication service activation server) based on a dedicated bearer, terminal device 100 may display a user interface 730 as shown in FIG7C. This user interface 730 may include text prompts instructing user A to input real-name authentication information (e.g., "name," "ID number," "mobile phone number," etc.). Terminal device 100 may detect operations involving inputting real-name authentication information (e.g., name, ID number, mobile phone number, etc.) and confirming real-name authentication information (e.g., detecting an operation to click option 731). After detecting the operation to confirm real-name authentication information (e.g., detecting an operation to click option 731), terminal device 100 may display a user interface 740 as shown in FIG7D. This user interface 740 may include a menu bar for satellite communication service packages (e.g., menu bar 741). Terminal device 100 may detect selection operations for the menu bar (e.g., menu bar 741) for satellite communication service packages (e.g., detecting an operation to select satellite package 1). After detecting a selection operation on a menu bar (e.g., menu bar 741) for a satellite communication service package (e.g., detecting the selection of satellite package 1), terminal device 100 can send billing information to a server (e.g., a satellite communication service activation server). This billing information can be included in the satellite communication service activation request. After receiving a notification confirming the billing information from the server (e.g., the satellite communication service activation server), terminal device 100 can display a user interface 750 as shown in FIG7E. This user interface 750 can include one or more payment options for activating a satellite communication service package (e.g., option 751, option 752). Terminal device 100 can detect a click operation on a payment option for activating a satellite communication service package (e.g., option 751, option 752) (e.g., detecting a click on option 751).

[0228] S105. The server grants terminal device 100 permission to access the public Internet and returns a notification to terminal device 100 that the satellite communication service has been successfully activated.

[0229] Specifically, after detecting a click operation on the payment options (e.g., options 751 and 752) for activating a satellite communication service package (e.g., clicking option 751), terminal device 100 can submit billing information to the payment server and display the payment interface for activating the satellite communication service package (user interface 760 as shown in Figure 7F). Upon detecting user A's payment operation, the payment server can return a notification of bill payment completion to the server (e.g., the satellite communication service activation server). After receiving the notification of bill payment completion, the server (e.g., the satellite communication service activation server) can grant terminal device 100 access to the public internet and return a notification of successful satellite communication service activation to terminal device 100.

[0230] In this embodiment of the application, the permission granted by the server (e.g., a satellite communication service activation server) to the terminal device 100 to access the public Internet can specifically mean that the server (e.g., a satellite communication service activation server) grants the terminal device 100 the permission to access the public Internet to send and receive data packets.

[0231] In some embodiments, after the server (e.g., a satellite communication service activation server) returns a notification of successful satellite communication service activation to the terminal device 100, the terminal device 100 may shut down the dedicated bearer to prevent the terminal device 100 from continuously occupying bearer resources. It is understood that the duration of the dedicated bearer activation is based on empirical data determined according to the service type of the dedicated bearer.

[0232] In other embodiments, after the server (e.g., a satellite communication service activation server) returns a notification of successful satellite communication service activation to the terminal device 100, the terminal device 100 may send a notification to the satellite core network 23 to close the dedicated bearer. Upon receiving the notification from the terminal device 100 to close the dedicated bearer, the satellite core network 23 may close the dedicated bearer to prevent the terminal device 100 from continuously occupying bearer resources. It is understood that the duration of the dedicated bearer activation is empirical data determined based on the service type of the dedicated bearer.

[0233] S106, Terminal device 100 accesses the public Internet.

[0234] In some embodiments, after receiving a notification that the satellite communication service has been successfully activated, terminal device 100 can activate user A's key and access the public internet based on the activated key. In this way, terminal device 100 can access the public internet to send and receive data packets.

[0235] It is understandable that the above steps for activating satellite communication services based on dedicated bearers can be detected using network logs or protocol flow analysis, and simultaneously aided by feature recognition of the user interface for evidence collection.

[0236] In other embodiments, if the terminal device 100 includes a terrestrial operator's eSIM, that is, if the terminal device 100 includes a cellular communication profile, the cellular communication profile may contain authentication information, which may include user A's identity information and key. The request for access to the public Internet sent by the terminal device 100 to the satellite core network 23 may include this authentication information. The satellite core network 23 can determine whether the terminal device 100 is configured with satellite communication services through the authentication information in the cellular communication profile. If the terminal device 100 is not configured with satellite communication services, the satellite core network 23 can establish a dedicated bearer with the terminal device 100. The subsequent specific process can be referred to steps S104-S106, and will not be repeated here.

[0238] Figure 4 illustrates the specific process of a bill payment method provided in an embodiment of this application.

[0239] As shown in the figure, the method may include:

[0243] S203, Terminal device 100 submits bill information to the payment server.

[0244] S204. The payment server returns a notification to the server that the bill payment is complete.

[0245] S205. The server returns a notification of service activation to the terminal device 100.

[0246] Specifically, terminal device 100 can send confirmed bill information to the payment server. Upon detecting user A's payment operation, the payment server can return a bill payment completion notification to the server (e.g., a satellite communication service activation server). After receiving the bill payment completion notification, the server (e.g., a satellite communication service activation server) can activate the service for terminal device 100 (e.g., grant terminal device 100 permission to access the public internet) and send a service activation notification to terminal device 100 (e.g., a notification of successful satellite communication service activation).

[0247] For example, bill payment methods may include QR code payment and bank card payment.

[0320] Based on the method flow illustrated in Figure 3, the following will describe in detail a series of graphical user interfaces provided by the embodiments of this application. A graphical user interface is essentially a human-computer interaction method, and is an interface control method for the terminal device 100.

[0321] As shown in Figure 7A, in some embodiments, the terminal device 100 can detect the operation of activating satellite communication services before sending a request to the satellite core network 23 to access the public Internet.

[0322] For example, as shown in FIG7A, the terminal device 100 may display a user interface 710, which may include a satellite communication service activation control (such as control 711) in a closed state, which can be used to activate the satellite communication service.

[0323] Terminal device 100 can receive input operations (e.g., clicks) from users on the control for activating satellite communication services. In response to such input operations, terminal device 100 can send a request to the satellite core network 23 to access the public Internet.

[0324] As shown in Figures 7B-7E, in some embodiments, after the satellite core network 23 and the terminal device 100 establish a dedicated bearer, the terminal device 100 can receive the real-name authentication information input by the user and the satellite communication service package information selected by user A from the menu bar of the satellite communication service package, and generate billing information.

[0325] For example, as shown in FIG7B, the terminal device 100 may display a user interface 720, which may include a prompt box (such as prompt box 721). The prompt box may include text prompt information for prompting the user to perform real-name authentication (e.g., "It has been detected that you have not activated a satellite package. Please perform real-name authentication"). In some embodiments, the type of prompt information included in the prompt box 721 may also be an image, video, sound, etc., and this application embodiment does not limit this. In addition, the prompt box may also include one or more options (such as option 722), which can be used to trigger the terminal device 100 to determine that the user has entered the real-name authentication process.

[0326] Terminal device 100 can receive input operations (e.g., clicks) performed by a user on option 722, and in response to such input operations, terminal device 100 can display user interface 730 as shown in FIG7C.

[0327] For example, as shown in FIG7C, the terminal device 100 may display a user interface 730, which may include text prompts (such as "name", "ID number", "mobile phone number", etc.) and options 731 for instructing the user to enter real-name authentication information. Option 731 can be used to confirm the real-name authentication information entered by the user.

[0328] After receiving the user's input of real-name authentication information (such as name, ID number, mobile phone number, etc.), the terminal device 100 can receive the user's input operation on option 731 (such as clicking). In response to the input operation, the terminal device 100 can display the user interface 740 as shown in Figure 7D.

[0329] For example, as shown in FIG7D, the terminal device 100 may display a user interface 740, which may include a menu bar (e.g., menu bar 741) for satellite communication service packages, which provides users with selectable satellite communication service packages.

[0330] Terminal device 100 can receive a user's click operation on the menu bar of a satellite communication service package (e.g., selecting satellite package 1). In response to this input operation, terminal device 100 can send billing information to a server (e.g., a satellite communication service activation server). This billing information can be included in the satellite communication service activation request. After receiving a notification confirming the billing information from the server (e.g., the satellite communication service activation server), terminal device 100 can display the user interface 750 as shown in FIG7E.

[0331] For example, as shown in FIG7E, the terminal device 100 may display a user interface 750, which may include one or more payment options for activating a satellite communication service package (e.g., option 751, option 752), which can be used by the user to select a payment method for the satellite communication service package.

[0332] Terminal device 100 can receive a user's click operation on the payment option for activating a satellite communication service package (e.g., clicking option 751). In response to this input operation, terminal device 100 can submit billing information to the payment server and display the payment interface for activating the satellite communication service package (user interface 760 as shown in Figure 7F).

[0333] As shown in Figures 7F-7G, in some embodiments, terminal device 100 can detect user A's payment operation (e.g., using a terminal device other than terminal device 100 to scan the QR code in user interface 760 as shown in Figure 7F to make a payment). After receiving a notification from the payment server that the bill payment is complete, the server (e.g., a satellite communication service activation server) can grant terminal device 100 permission to access the public Internet, and the server (e.g., a satellite communication service activation server) can also return a notification to terminal device 100 that the satellite communication service has been successfully activated. After receiving the notification that the satellite communication service has been successfully activated, terminal device 100 can display user interface 770 as shown in Figure 7G.

[0334] For example, as shown in FIG7G, the terminal device 100 may display a user interface 770, which may include a prompt box (e.g., prompt box 771). The prompt box may include text prompt information to inform the user that the satellite communication service package has been successfully activated (e.g., "You have successfully paid, and the satellite package has been activated"). In some embodiments, the type of prompt information included in the prompt box 771 may also be an image, video, sound, etc., and this application embodiment does not limit this.

[0335] After the satellite communication service is activated, the terminal device 100 can display the user interface 780 shown in Figure 7H. The user interface 780 may include a control for activating the satellite communication service (such as control 781) that is in an open state.

[0336] In some embodiments, the aforementioned user interfaces are optional, such as user interfaces 720 and 730 related to real-name authentication, user interface 780 notifying the user of successful activation of the satellite communication service package, etc. This application embodiment does not limit this.

[0337] (II) Example 2

[0338] In other embodiments, in a satellite calling scenario, terminal device 100 can send calling signaling A to satellite network device 200. Calling signaling A includes a calling number and a called number; wherein the calling number is user A's satellite number and the called number is user B's number; satellite network device 200 can determine user A's cellular number from database A based on user A's satellite number, and database A includes user A's satellite number and cellular number; satellite network device 200 can send calling signaling B to user B's terminal device 300. The calling number in calling signaling B is user A's cellular number, and the called number in calling signaling B is user B's number; after receiving calling signaling B, terminal device 300 can display the calling number (i.e., user A's cellular number) in calling signaling B. In this way, after the satellite communication service is activated, when terminal device 100 (the calling party) calls other numbers of terminal device 300 (the called party) using the satellite number, terminal device 300 (the called party) can display the calling party's cellular number, keeping the cellular number and satellite number received by the called party consistent and improving the user experience of the called party.

[0339] The following is a flowchart illustrating another notification method provided in an embodiment of this application.

[0340] Figure 8 illustrates the specific flow of another notification method provided in an embodiment of this application. This method can be applied to a communication system including terminal device 100 and satellite network device 200.

[0341] As shown in Figure 8, the method may include:

[0342] S501, satellite core network 23 and ground core network 43 are authorized to use numbers.

[0343] Specifically, terminal device 100 can send user A's cellular number to satellite core network 23. After receiving user A's cellular number from terminal device 100, satellite core network 23 can associate user A's satellite number and cellular number, and store user A's satellite number and cellular number in database A.

[0344] In some embodiments, database A may be located on a core network element of a communication system including terminal device 100 and satellite network device 200. Not limited to satellite core network 23, database A may also be located on terrestrial core network 43 (cellular core network 43).

[0345] In some embodiments, terminal device 100 can send a short message to satellite core network 23 using user A's satellite number, the content of which includes user A's cellular number. For example, terminal device 100 can send the short message "HMZH+1888888888" to the customer service number of satellite core network 23 using user A's satellite number "88888", where "1888888888" is user A's cellular number.

[0346] In other embodiments, terminal device 100 can log in to a server connected to satellite core network 23 and send a message to that server. This message can be used to instruct user A's satellite number to be changed to user A's cellular number. The server can then forward this message to satellite core network 23. Not limited to forwarding the message, the server can also forward user A's cellular number and satellite number to satellite core network 23. For example, terminal device 100 can log in to a number modification server connected to satellite core network 23 and send the message "88888+1888888888" to that server. The server can then forward this message to satellite core network 23. Satellite core network 23 can associate user A's satellite number "88888" and cellular number "1888888888" and store user A's satellite number and cellular number in database A.

[0347] The specific negotiation mechanism for number authorization between the satellite core network 23 and the ground core network 43 can be found in the relevant explanation in Figure 9, which will not be elaborated here.

[0348] S502, Terminal device 100 initiates a call.

[0349] Specifically, terminal device 100 can send calling signaling A to satellite core network 23. Calling signaling A includes calling number and called number; where the calling number is user A's satellite number and the called number is user B's number.

[0350] In some embodiments, the called number in the calling signaling A may belong to a satellite communication operator or a cellular communication operator.

[0351] S503, Satellite Core Network 23 conversion number.

[0352] Specifically, the satellite core network 23 can determine the cellular number of user A from database A based on user A's satellite number, where database A includes user A's satellite number and cellular number.

[0353] In some embodiments, database A may include a home location register (HLR).

[0354] The specific number conversion process in the satellite core network 23 can be found in the relevant explanation in Figure 9, which will not be elaborated here.

[0355] S504, Satellite Core Network 23 carries cellular number for calls.

[0356] Specifically, the satellite core network 23 can send calling signaling B to other core networks 46 (cellular core network 46), where the calling number in calling signaling B is the cellular number of user A, and the called number in calling signaling B is the number of user B.

[0357] S505, Terminal device 300 displays cellular number.

[0358] Specifically, after receiving the calling signaling B, the terminal device 300 can display the calling number (i.e., user A's cellular number) in the calling signaling B.

[0359] In this way, after the satellite communication service is activated, when terminal device 100 (the calling party) calls other numbers of terminal device 300 (the called party) using the satellite number, terminal device 300 (the called party) can display the calling party's cellular number, keeping the cellular number and satellite number received by the called party consistent and improving the user experience of the called party.

[0360] In other embodiments, in a satellite-based called scenario, terminal device 300 can initiate a call (i.e., broadcast a paging message in other core networks 46) to other core networks 46 (cellular core networks 46) at a preset frequency (e.g., every 2.5 seconds). Other core networks 46 (cellular core networks 46) can send the paging message to other access networks 45 (cellular access networks 45), which in turn can send the paging message to a paging domain. The paging domain can then notify terminal device 100 to receive the paging message. If terminal device 100 does not receive the paging message within a preset time (e.g., 15 seconds), the paging process fails. If terminal device 300 detects that the user has enabled call forwarding service, other core networks 46 (cellular core networks 46) can send the calling signaling in the paging message to the ground core network 43 (cellular core network 43) so that the ground core network 43 (cellular core network 43) can forward the calling signaling call.

[0361] S506, Terminal device 300 initiates the call.

[0362] Specifically, terminal device 300 can send calling signaling C to other core network 46 (cellular core network 46), where the called number in calling signaling C is user A's cellular number.

[0363] S507. If paging fails, other core networks 46 send calling signaling to ground core networks 43.

[0364] S508, Ground Core Network 43 Call Transfer.

[0365] S509 and Satellite Core Network 23 initiated satellite paging.

[0366] Specifically, the other core network 46 (cellular core network 46) can determine that the call to user A's cellular number has failed. After determining that the call to user A's cellular number has failed, if the terminal device 300 detects that the user has enabled call forwarding service, the other core network 46 (cellular core network 46) can send the calling signaling C to the terrestrial core network 43 (cellular core network 43). After receiving the calling signaling C, the terrestrial core network 43 (cellular core network 43) can send the calling signaling D to the satellite core network 23, where the called number in the calling signaling D is user A's satellite number. After receiving the calling signaling D, the satellite core network 23 can send the calling signaling D to the terminal device 100.

[0367] In some embodiments, not limited to the terminal device 300 described above which forwards cellular number calls to satellite numbers, the terminal device may also forward satellite number calls to cellular numbers.

[0368] Specifically, the satellite core network 23 can receive calling signaling E from the terminal device 300, where the called number in calling signaling E is the satellite number of user A; the satellite core network 23 can determine that the call to user A's satellite number has failed; after determining that the call to user A's satellite number has failed, the satellite core network 23 can send calling signaling F to the terminal device 100, where the called number in calling signaling F is the cellular number of user A.

[0369] In other embodiments, the terminal device may also forward calls from one of User A's satellite numbers to another of User A's satellite numbers.

[0370] Specifically, the satellite core network 23 can receive calling signaling G from the terminal device 300, where the called number in the calling signaling G is the satellite number A of user A; the satellite core network 23 can determine that the call to user A's satellite number A failed; after determining that the call to user A's satellite number A failed, the satellite core network 23 can send calling signaling H to the terminal device 100, where the called number in the calling signaling H is user A's satellite number B, which is different from satellite number A.

[0371] In other embodiments, the terminal device may also forward calls from one of User A's cellular numbers to another of User A's cellular numbers.

[0372] Specifically, other core network 46 (cellular core network 46) can receive calling signaling J from terminal device 300, where the called number in calling signaling J is user A's cellular number A; other core network 46 (cellular core network 46) can determine that calling user A's cellular number A has failed; after determining that calling user A's cellular number A has failed, other core network 46 (cellular core network 46) can send calling signaling K to terminal device 100, where the called number in calling signaling K is user A's cellular number B, which is different from cellular number A.

[0373] The following is a flowchart illustrating a number authorization and number conversion method provided in an embodiment of this application.

[0374] Figure 9 illustrates, exemplarily, the specific flow of a number authorization and number conversion method provided in an embodiment of this application. Taking database A as an example, which is the HLR on satellite core network 23.

[0375] As shown in Figure 9, the method may include:

[0376] S601, HLR requests number authorization.

[0377] S602, Ground Core Network 43 returns cellular numbers.

[0378] Specifically, the number authorization process between the satellite core network 23 and the ground core network 43 (cellular core network 43) may include: after the satellite communication service is activated, the HLR can send a number authorization request to the ground core network 43 (cellular core network 43); after receiving the number authorization request sent by the HLR, the ground core network 43 (cellular core network 43) can return user A's cellular number to the HLR. The HLR can associate user A's satellite number and cellular number and store user A's satellite number and cellular number in the HLR.

[0379] S603, UPF sends calling signaling.

[0380] The S604 and IMS protocol stack transmit satellite numbers.

[0381] S605, HLR sends cellular numbers.

[0382] The S606 and IMS protocol stack carry cellular number calls.

[0383] Specifically, the number translation process of the satellite core network 23 may include: after receiving the calling signaling A (e.g., Session Initiation Protocol (SIP) signaling) sent by the terminal device 100, the UPF can send the calling signaling A to the IP Multimedia Subsystem (IMS) protocol stack. The calling signaling A contains the calling number and the called number; wherein the calling number is the satellite number of user A, and the called number is the number of user B; after receiving the calling signaling A, the IMS protocol stack can send the calling number (i.e., the satellite number of user A) in the calling signaling A to the HLR; the HLR can return the cellular number associated with the satellite number of user A to the IMS protocol stack; after receiving the cellular number of user A, the IMS protocol stack can send the calling signaling B to the terrestrial core network 43 (cellular core network 43). The calling number in the calling signaling B is the cellular number of user A, and the called number in the calling signaling B is the number of user B.
