Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus, and electronic device for switching between satellite networks and mobile communication networks. Background Technology

[0002] CPE (Customer Premise Equipment) refers to client-side devices in a network. It converts 4G or 5G wireless signals received from the operator's base station into WiFi or wired signals for use by terminal devices, enabling more devices to access the internet. In scenarios where both 5G and satellite networks can be connected, the CPE typically uses dual WAN ports to select either satellite or 5G network signals as the access signal, forwarding them through a router to the LAN port for output to the terminal devices.

[0003] When multiple terminal devices access the satellite network through a CPE, since all the terminal devices are connected through the WAN port address of the CPE, meaning that the uplink ports all correspond to the same address, the satellite master station will treat the multiple terminal devices as the same user. This will result in problems such as authentication information not being able to be distinguished independently, chaotic account and fee calculations, and abnormal loss of account traffic. Summary of the Invention

[0004] The purpose of this invention is to provide a method, apparatus, and electronic device for switching between satellite networks and mobile communication networks, in order to solve the problems in the prior art.

[0005] To solve the above-mentioned technical problems, the embodiments of the present invention are implemented as follows:

[0006] In a first aspect, embodiments of the present invention provide a method for switching between a satellite network and a mobile communication network, comprising:

[0007] When connected to a mobile communication network, the working mode is set to routing mode, an IP address is assigned to the terminal, the mobile communication network signal is received from the WAN port and converted into a local area network signal, and the local area network signal is routed and forwarded to the terminal according to the IP address.

[0008] Based on preset parameters, detect whether the current mobile communication network signal meets the handover conditions;

[0009] If the switching conditions are met, the system accesses the satellite network, switches the operating mode to switching mode, receives satellite network signals from the WAN port and converts them into LAN signals, and forwards the LAN signals to the terminal according to the IP address assigned to the terminal by the satellite station.

[0010] Secondly, embodiments of the present invention provide a switching device between a satellite network and a mobile communication network, comprising:

[0011] The first processing module is used to set the working mode to routing mode when accessing the mobile communication network, assign an IP address to the terminal, receive mobile communication network signals from the WAN port and convert them into local area network signals, and route and forward the local area network signals to the terminal according to the IP address.

[0012] The detection module is used to detect whether the current mobile communication network signal meets the handover conditions based on preset parameters;

[0013] The second processing module is used to access the satellite network if the switching conditions are met, switch the working mode to the switching mode, receive satellite network signals from the WAN port and convert them into local area network signals, and forward the local area network signals to the terminal according to the IP address assigned to the terminal by the satellite terminal.

[0014] Thirdly, embodiments of the present invention provide an electronic device, including a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the satellite network and mobile communication network switching method provided in the above embodiments.

[0015] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, implements the steps of the satellite network and mobile communication network switching method provided in the above embodiments.

[0016] Fifthly, embodiments of the present invention provide a computer program product, including a computer program that, when executed by a processor, implements the steps of the satellite network and mobile communication network switching method provided in the above embodiments.

[0017] As can be seen from the technical solutions provided by the above embodiments of the present invention, the embodiments of the present invention, when accessing a mobile communication network, set the working mode to routing mode, assign an IP address to the terminal, receive mobile communication network signals from the WAN port and convert them into local area network signals, and route and forward the local area network signals to the terminal according to the IP address. Based on preset parameters, it detects whether the current mobile communication network signal meets the switching conditions. If the switching conditions are met, it accesses the satellite network, switches the working mode to switching mode, receives satellite network signals from the WAN port and converts them into local area network signals, and forwards the local area network signals to the terminal according to the IP address assigned to the terminal by the satellite station. This realizes the automatic switching between the mobile communication network and the satellite network. Since the IP address of the terminal in the scenario connected to the satellite network is assigned by the satellite station, the satellite master station can distinguish multiple terminals, ensuring the normal use of the satellite network function and avoiding problems such as authentication information not being able to be independently distinguished, chaotic account and fee calculation, and abnormal loss of account traffic.

[0027] This invention provides a method, apparatus, and electronic device for switching between satellite networks and mobile communication networks.

[0028] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0029] First, the terms used in this invention will be explained.

[0030] CPE (Customer Premise Equipment): refers to client devices in a network. It can convert 4G or 5G wireless signals received from the operator's base station into WiFi or wired signals for use by terminal devices, thereby enabling more terminal devices to access the Internet.

[0031] RSSI (Received Signal Strength Indication) is a metric for measuring the strength of a received wireless signal. It indicates the strength of the received wireless signal. RSSI can be used to determine the quality, coverage, interference level, transmission quality, reliability, and source of the wireless signal. A higher RSSI value indicates a stronger signal, a wider coverage area, and less interference; conversely, a lower RSSI value indicates a weaker signal, a smaller coverage area, and greater interference. RSSI has important applications in wireless communication and is a crucial indicator of its performance.

[0032] RSRP (Reference Signal Receiving Power): refers to the linear average of the received power on all REs (Resource Elements) carrying the reference signal over the measurement frequency bandwidth.

[0033] 5G NR (New Radio): Developed by 3GPP for fifth-generation mobile communication networks (5G), it is a globally universal standard for the 5G network air interface. It is generally divided into two frequency ranges, FR1 and FR2, encompassing a total of 29 frequency bands. The 5G NR standard differs significantly from previous generations of wireless standards. It is a global 5G standard based on a completely new air interface design using OFDM (Orthogonal Frequency Division Multiplexing), employing a new end-to-end network architecture that can provide extremely high data throughput and highly reliable low-latency connections.

[0034] The satellite network and mobile communication network switching method and apparatus provided in this invention can be applied in CPEs, such as gateways or routers. Application scenarios for the above method and apparatus include, but are not limited to, scenarios where mobile communication network signal coverage is weak and switching to satellite networks is necessary, such as in ship, desert, earthquake, or flood scenarios. The mobile communication networks include, but are not limited to, 3G, 4G, or 5G networks. 5G networks include, but are not limited to, the FR1 or FR2 bands. The FR1 band, or Sub-6GHz band, has a frequency range of 450MHz-6000MHz and includes 26 frequency bands such as n1 / n2 / n3, including bands like 450MHz, 700MHz, 2.6GHz, or 5GHz. The FR2 band, or millimeter-wave band, has a frequency range of 24250MHz-52600MHz and includes 7 frequency bands such as n1 / n3 / n28 / n41 / n77 / n78 / n79, including bands like 24GHz, 28GHz, or 39GHz.

[0035] The method and apparatus provided in the embodiments of the present invention, since the IP address of the terminal in the scenario connected to the satellite network is assigned by the satellite terminal station, enable the satellite master station to distinguish multiple terminals, thereby avoiding problems such as the inability to independently distinguish authentication information, chaotic account fee calculation, and abnormal loss of account traffic.

[0036] like Figure 1 As shown, this embodiment of the invention provides a method for switching between a satellite network and a mobile communication network, which may specifically include the following steps.

[0037] In S102, when accessing a mobile communication network, the working mode is set to routing mode, an IP address is assigned to the terminal, the mobile communication network signal is received from the WAN port and converted into a local area network signal, and the local area network signal is routed and forwarded to the terminal according to the IP address.

[0038] In this embodiment of the invention, the routing mode refers to the CPE's function of routing and forwarding signals from the mobile communication network. In this scenario, the CPE and the terminal belong to a hierarchical network, with the mobile communication network being the upper-layer network. The signals are routed and forwarded by the CPE to the terminal in the lower-layer network.

[0039] In S104, the current mobile communication network signal is detected based on preset parameters to determine whether the handover conditions are met.

[0040] In this embodiment of the invention, whether the current mobile communication network signal meets the handover conditions can be determined by using RSSI, or by using ping packets, or by using both RSSI and ping packets simultaneously; the specific method is not limited.

[0041] In one implementation, step S104 may include any of the following:

[0042] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is lower than the preset handover threshold, the current mobile communication network signal meets the handover conditions.

[0043] The status of ping packets sent to the specified address is monitored in real time. If the ping packet delay exceeds the preset handover time, the current mobile communication network signal meets the handover conditions.

[0044] The RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address are detected in real time. If the RSSI is lower than the handover threshold or the ping packet delay exceeds the handover duration, the current mobile communication network signal meets the handover conditions.

[0045] In this embodiment of the invention, the number of ping packets can be set as needed, including one or more, such as three or four. Specifically, when there are multiple ping packets, the ping packet latency exceeding the handover time means that the latency of all ping packets exceeds the handover time.

[0046] In S106, if the switching conditions are met, the system accesses the satellite network, switches the working mode to switching mode, receives satellite network signals from the WAN port and converts them into LAN signals, and forwards LAN signals to the terminal according to the IP address assigned to the terminal by the satellite station.

[0047] In this embodiment of the invention, the switching mode refers to the CPE only having the function of forwarding signals from the mobile communication network without performing any judgment or processing. In this scenario, the CPE and the terminal belong to the same network layer, and the mobile communication network signals are directly forwarded from the CPE to the terminal without judgment or processing.

[0048] In this embodiment of the invention, the preset parameters may include a validity period, and correspondingly, the IP address of the terminal is valid within the validity period.

[0049] In one implementation, after switching the working mode to the switching mode in step S106, the method may further include: detecting whether the current mobile communication network signal meets the recovery conditions based on preset parameters; if the recovery conditions are met, switching the working mode back to the switching mode and resuming communication using the mobile communication network.

[0050] In another implementation, after switching the operating mode to the switching mode in step S106 above, it may also include any of the following:

[0051] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is higher than the preset recovery threshold, the working mode switching loop is switched to mode 1 to resume communication using the mobile communication network.

[0052] The system monitors the status of ping packets sent to the specified address in real time. If the ping packet delay is less than the preset recovery time, the system switches the working mode to loopback mode and resumes communication using the mobile communication network.

[0053] The system monitors the RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address in real time. If the RSSI is higher than the recovery threshold or the ping packet delay is lower than the recovery time, the working mode is switched to loopback mode to resume communication using the mobile communication network.

[0054] The recovery threshold can be greater than the handover threshold to avoid frequent network handovers and signal instability.

[0055] The method provided in this embodiment of the invention enables automatic switching between mobile communication networks and satellite networks. Since the IP address of the terminal connected to the satellite network is assigned by the satellite station, the satellite master station can distinguish multiple terminals, ensuring the normal use of satellite network functions and avoiding problems such as authentication information not being able to be distinguished independently, chaotic account fee calculation, and abnormal loss of account traffic.

[0056] like Figure 2 As shown, this embodiment of the invention provides another method for switching between satellite networks and mobile communication networks, which may specifically include the following steps.

[0057] In S202, configure the parameters of CPE.

[0058] In this embodiment of the invention, the parameters for configuring the CPE can be the automatic default configuration during initialization, or they can be configured manually; there is no specific limitation. The CPE parameters include, but are not limited to: WAN port information, LAN port information, destination address information for detecting network connections, or ping packet information, etc., and there is no specific limitation.

[0059] In this embodiment of the invention, the CPE has dual WAN ports: one for connecting to a mobile communication network, such as wirelessly connecting to a base station of a mobile communication network; and the other for connecting to a satellite network, such as connecting to the LAN port of a satellite terminal station. The CPE also has a LAN port for connecting terminals.

[0060] In one implementation, when configuring the CPE parameters, the LAN port information can be specifically configured, including but not limited to: the LAN port's IP address and subnet mask information.

[0061] Figure 3 The diagram shown is a schematic representation of configuring LAN port information according to an embodiment of the present invention. (See also...) Figure 3When configuring the CPE parameters, you can configure the LAN port information, which can be done through the configuration interface. Specifically, configure the LAN port's IPv4 address as 192.168.1.1 and the IPv4 subnet mask as 255.255.255.0.

[0062] In one implementation, when configuring the CPE parameters, the destination address for detecting network connectivity can be specifically configured to detect whether the CPE is connected to the external network. The destination address for detecting external network connectivity can be a domestic public DNS address, such as 114.114.114.114 or 223.5.5.5, or it can be configured as the address of the main station-side server on the satellite intranet; the specific configuration is not limited.

[0063] Figure 4 This is a schematic diagram illustrating the configuration for detecting the destination address provided in an embodiment of the present invention. See also... Figure 4 When configuring CPE parameters, you can configure the destination address information for network connection detection. Specifically, configure the destination address to the address of the master station's server on the satellite intranet, such as the address of the peer leased line server: 192.168.16.14. By configuring the destination address for network connection detection to the address of the master station's server on the satellite intranet, you can ensure normal pinging when the satellite station joins the network, preventing restarts and network interruptions.

[0064] In one implementation, when configuring CPE parameters, ping packet information can be specifically configured, including but not limited to the switching duration of ping packet delay and the number of ping packets.

[0065] Figure 5 This is a schematic diagram illustrating the configuration of RSSI and ping packet information according to an embodiment of the present invention. See also... Figure 5 When configuring CPE parameters, the RSSI information can be specifically configured as follows: the handover threshold for 4G RSSI is 8, and the handover threshold for 5G RSSI is 10. This means that if the RSSI of the 4G network is lower than 8, the current 4G network signal meets the handover conditions; if the RSSI of the 5G network is lower than 10, the current 5G network signal meets the handover conditions and can be switched to the satellite network. Additionally, the ping packet information can be configured as follows: the handover duration for ping packet latency is 500ms, and the number of ping packets is 4. This means that if no response is received from the other end after sending 4 ping packets (more than 500ms), it is considered packet loss, and the handover conditions are met, allowing switching to the satellite network.

[0066] In this embodiment of the invention, the switching duration of the ping packet delay can be set as needed, such as 200ms, 300ms, or 500ms, etc., and the specific value is not limited. Setting a higher switching duration ensures that the signal will not switch immediately when encountering short-term signal fluctuations, avoiding triggering overly sensitive switching that leads to frequent switching, and also avoiding false packet loss. Setting a lower switching duration is suitable for scenarios with high network quality requirements.

[0067] In S204, when accessing a mobile communication network, the working mode is set to routing mode, an IP address is assigned to the terminal, the mobile communication network signal is received from the WAN port and converted into a local area network signal, and the local area network signal is routed and forwarded to the terminal according to the IP address.

[0068] Setting the operating mode to routing mode can also include: disabling the WAN port of the CPE used for connecting to the satellite network, thereby ensuring that the WAN port used for connecting to the mobile communication network works effectively.

[0069] In S206, the current mobile communication network signal is detected based on RSSI and / or ping packets to determine whether the handover conditions are met.

[0070] In one implementation, step S206 may specifically include any of the following:

[0071] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is lower than the preset handover threshold, the current mobile communication network signal meets the handover conditions.

[0072] The status of ping packets sent to the specified address is monitored in real time. If the ping packet delay exceeds the preset handover time, the current mobile communication network signal meets the handover conditions.

[0073] The RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address are detected in real time. If the RSSI is lower than the handover threshold or the ping packet delay exceeds the handover duration, the current mobile communication network signal meets the handover conditions.

[0074] In this embodiment of the invention, the handover threshold can be set according to the type of mobile communication network. For example, the handover threshold for 4G RSSI is set to 8 (equivalent to an RSRP value of -102dBm to -106dBm), and the handover threshold for 5G RSSI is set to 10 (equivalent to an RSRP value of -99dBm to -95dBm), thereby maintaining a balance between signal quality and available distance when using a shore-based mobile communication network.

[0075] In this embodiment of the invention, when there are multiple ping packets, the ping packet delay exceeding a specified duration means that the delay of all ping packets exceeds the specified duration.

[0076] In S208, if the switching conditions are met, the system accesses the satellite network, switches the working mode to switching mode, receives satellite network signals from the WAN port and converts them into LAN signals, and forwards LAN signals to the terminal according to the IP address assigned to the terminal by the satellite station.

[0077] Switching the operating mode to switching mode may also include: activating the WAN port of the CPE used for connecting to the satellite network and disabling the WAN port of the CPE used for connecting to the mobile communication network, thereby ensuring that the WAN port used for connecting to the satellite network works effectively.

[0078] It should be noted that during communication using the satellite network, the CPE maintains connection detection, i.e., detection based on RSSI and / or ping packets, so that it can quickly switch back to the mobile communication network when the mobile communication network signal is restored.

[0079] In this embodiment of the invention, whether the CPE assigns an IP address to the terminal or the satellite station assigns an IP address to the terminal, the DHCP service can be used to complete the assignment, which will not be explained in detail here.

[0080] In S210, the current mobile communication network signal is detected based on RSSI and / or ping packets to see if the recovery conditions are met. If the recovery conditions are met, the working mode switching loop is switched from mode to mode, and communication using the mobile communication network is resumed.

[0081] In one implementation, step S210 may specifically include any of the following:

[0082] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is higher than the preset recovery threshold, the working mode switching loop is switched to mode 1 to resume communication using the mobile communication network.

[0083] The system monitors the status of ping packets sent to the specified address in real time. If the ping packet delay is less than the preset recovery time, the system switches the working mode to loopback mode and resumes communication using the mobile communication network.

[0084] The system monitors the RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address in real time. If the RSSI is higher than the recovery threshold or the ping packet delay is lower than the recovery time, the working mode is switched to the loop mode to resume communication using the mobile communication network.

[0085] Among them, the recovery threshold is greater than the switching threshold.

[0086] In this embodiment of the invention, the recovery threshold can be set according to the type of mobile communication network. For example, the recovery threshold for 4G RSSI is set to 14, and the recovery threshold for 5G RSSI is set to 16, both of which are 6 units higher than the handover threshold, meaning the recovery threshold is greater than the handover threshold. This method ensures that there will not be multiple repeated handovers in a short period of time at the signal critical point.

[0087] In this embodiment of the invention, the preset parameters may include a validity period, which can be set as needed, such as 4-24 hours. Correspondingly, the IP address of the terminal is valid within the validity period. Specifically, both the IP address assigned to the terminal by the CPE and the IP address assigned to the terminal by the satellite station are valid within this validity period.

[0088] In this embodiment of the invention, regardless of whether mobile communication network or satellite network communication is used, the terminal can access the network based on the allocated IP address, after passing local device authentication and BRAS internet access permission from the backend master station using encrypted authentication. Especially in the scenario of using satellite network, the terminal's network address is consistent with the service network segment of the satellite station, and it can normally pass device authentication and user authentication to connect to the satellite communication service network. Moreover, since the CPE itself does not participate in address allocation or identification, even after multiple handovers, the terminal's IP address stored by the satellite station will not change within the validity period of the IP address, and will be consistent with the IP address stored by the terminal. This avoids repeated authentication during multiple handovers, making the handover process smoother and the user experience more convenient.

[0089] Figure 6 This is a schematic diagram illustrating the network handover process based on RSSI and ping packets, provided as an embodiment of the present invention. See also... Figure 6 Taking a 5G mobile communication network as an example, the network handover process based on RSSI and ping packets can specifically include: CPE startup, checking SIM status, and if abnormal, switching to switching mode and accessing the satellite network for communication; if normal, accessing the 5G network. Determining whether 5G network access is successful: if it fails, switching back to switching mode and accessing the satellite network for communication; if successful, using routing mode to access the 5G network for communication. While accessing the 5G network, real-time network status monitoring: if the 5G RSSI reaches the detection threshold (e.g., above 8), continuing to monitor ping packet status; if the 5G RSSI does not reach the detection threshold (e.g., below 8), switching back to switching mode and accessing the satellite network for communication. The aforementioned ping packet status monitoring can include: determining whether the ping packet latency reaches the detection threshold (e.g., less than 500ms); if so, continuing to use the 5G network for communication; otherwise, switching back to switching mode and accessing the satellite network for communication.

[0090] In this embodiment of the invention, the test results obtained by conducting tests in near-shore waters are shown in Table 1.

[0091] Table 1

[0092]

[0093] In this context, "near-shore" refers to a test point within a straight-line distance of less than 15 kilometers from the optimal 5G base station, while "medium-long distance" refers to a test point within a straight-line distance of 15 kilometers or more from the optimal 5G base station. Table 1 shows that the network signal is stronger when using an outdoor antenna than when using an indoor antenna, and the network signal is stronger at near-shore distances than at medium-long distances.

[0094] The method provided in this invention enables automatic switching between mobile communication networks and satellite networks. Since the IP addresses of terminals connected to the satellite network are assigned by the satellite station, the satellite master station can distinguish between multiple terminals, ensuring the normal operation of the satellite network and avoiding problems such as inability to independently distinguish authentication information, chaotic account and fee calculations, and abnormal loss of account traffic. Furthermore, this method is well-suited for marine vessel scenarios, allowing for better operation in the varied and complex maritime environment. Especially in remote areas or marine regions, it provides excellent supplementation and connection between shore-based mobile network communication and satellite communication, leveraging the good coverage performance of mobile communication network frequency bands while also connecting to satellite communication networks, achieving a balance of cost and performance across a large geographical area.

[0095] The above describes the method for switching between satellite networks and mobile communication networks provided by embodiments of the present invention. Based on the same idea, embodiments of the present invention also provide a device for switching between satellite networks and mobile communication networks, such as... Figure 7 As shown, it specifically includes:

[0096] The first processing module 701 is used to set the working mode to routing mode when accessing a mobile communication network, assign an IP address to the terminal, receive mobile communication network signals from the WAN port and convert them into local area network signals, and route and forward the local area network signals to the terminal according to the IP address.

[0097] The detection module 702 is used to detect whether the current mobile communication network signal meets the handover conditions based on preset parameters.

[0098] The second processing module 703 is used to access the satellite network if the switching conditions are met, switch the working mode to the switching mode, receive satellite network signals from the WAN port and convert them into local area network signals, and forward local area network signals to the terminal according to the IP address assigned to the terminal by the satellite terminal.

[0099] In one implementation, the detection module 702 may be specifically used to perform any of the following:

[0100] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is lower than the preset handover threshold, the current mobile communication network signal meets the handover conditions.

[0101] The status of ping packets sent to the specified address is monitored in real time. If the ping packet delay exceeds the preset handover time, the current mobile communication network signal meets the handover conditions.

[0102] The RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address are detected in real time. If the RSSI is lower than the handover threshold or the ping packet delay exceeds the handover duration, the current mobile communication network signal meets the handover conditions.

[0103] In this embodiment of the invention, the number of ping packets can be preset as needed, including one or more. Specifically, when there are multiple ping packets, the "ping packet delay exceeding the handover time" means that the delay of all ping packets exceeds the handover time.

[0104] In one implementation, the second processing module 703 is further configured to: after switching the working mode to the switching mode, detect whether the current mobile communication network signal meets the recovery conditions based on preset parameters; if the recovery conditions are met, switch the working mode back to the switching mode and resume using the mobile communication network for communication.

[0105] In one implementation, the second processing module 703 is further configured to: after switching the operating mode to the switching mode, perform any of the following:

[0106] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is higher than the preset recovery threshold, the working mode switching loop is switched to mode 1 to resume communication using the mobile communication network.

[0107] The system monitors the status of ping packets sent to the specified address in real time. If the ping packet delay is less than the preset recovery time, the system switches the working mode to loopback mode and resumes communication using the mobile communication network.

[0108] The system monitors the RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address in real time. If the RSSI is higher than the recovery threshold or the ping packet delay is lower than the recovery time, the working mode is switched to loopback mode to resume communication using the mobile communication network.

[0109] In this embodiment of the invention, the recovery threshold can be greater than the switching threshold to avoid frequent network switching and network signal instability.

[0110] In this embodiment of the invention, the preset parameters may include a validity period, and correspondingly, the IP address of the terminal is valid within the validity period.

[0111] The device provided in this embodiment of the invention realizes automatic switching between mobile communication networks and satellite networks. Since the IP address of the terminal connected to the satellite network is assigned by the satellite station, the satellite master station can distinguish multiple terminals, ensuring the normal use of satellite network functions and avoiding problems such as authentication information not being able to be distinguished independently, chaotic account fee calculation, and abnormal loss of account traffic.

[0113] The processor 810 is used to set the working mode to routing mode when accessing a mobile communication network, assign an IP address to the terminal, receive mobile communication network signals from the WAN port and convert them into local area network signals, and route and forward the local area network signals to the terminal according to the IP address; detect whether the current mobile communication network signal meets the switching conditions based on preset parameters; if the switching conditions are met, access the satellite network, switch the working mode to switching mode, receive satellite network signals from the WAN port and convert them into local area network signals, and forward the local area network signals to the terminal according to the IP address assigned to the terminal by the satellite station.

[0114] In one implementation, the processor 810 may specifically be used to perform any of the following:

[0115] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is lower than the preset handover threshold, the current mobile communication network signal meets the handover conditions.

[0116] The status of ping packets sent to the specified address is monitored in real time. If the ping packet delay exceeds the preset handover time, the current mobile communication network signal meets the handover conditions.

[0117] The RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address are detected in real time. If the RSSI is lower than the handover threshold or the ping packet delay exceeds the handover duration, the current mobile communication network signal meets the handover conditions.

[0118] In one implementation, the processor 810 is further configured to: after switching the operating mode to the switching mode, detect whether the current mobile communication network signal meets the recovery conditions based on preset parameters; if the recovery conditions are met, switch the operating mode back to the switching mode and resume using the mobile communication network for communication.

[0119] In one implementation, the processor 810 is further configured to: after switching the operating mode to the switching mode, perform any of the following:

[0120] The RSSI of the current mobile communication network signal is detected in real time. If the RSSI is higher than the preset recovery threshold, the working mode switching loop is switched to mode 1 to resume communication using the mobile communication network.

[0121] The system monitors the status of ping packets sent to the specified address in real time. If the ping packet delay is less than the preset recovery time, the system switches the working mode to loopback mode and resumes communication using the mobile communication network.

[0122] The system monitors the RSSI of the current mobile communication network signal and the status of ping packets sent to the specified address in real time. If the RSSI is higher than the recovery threshold or the ping packet delay is lower than the recovery time, the working mode is switched to loopback mode to resume communication using the mobile communication network.

[0123] This invention provides an electronic device that enables automatic switching between mobile communication networks and satellite networks. Since the IP address of the terminal connected to the satellite network is assigned by the satellite station, the satellite master station can distinguish multiple terminals, ensuring the normal use of satellite network functions and avoiding problems such as authentication information not being able to be independently distinguished, chaotic account fee calculation, and abnormal loss of account traffic.

[0124] It should be understood that, in this embodiment of the invention, the radio frequency unit 801 can be used for receiving and transmitting signals during information transmission or calls.

[0126] The audio output unit 803 can convert audio data received by the radio frequency unit 801 or the network module 802 or stored in the memory 809 into audio signals and output them as sound. Furthermore, the audio output unit 803 can also provide audio output related to specific functions performed by the electronic device 800 (e.g., call signal reception sound, message reception sound, etc.). The audio output unit 803 includes a speaker, a buzzer, and a receiver, etc.

[0127] Input unit 804 is used to receive audio or video signals. Input unit 804 may include a graphics processing unit (GPU) 8041 and a microphone 8042. The GPU 8041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on display unit 806. The image frames processed by GPU 8041 can be stored in memory 809 (or other storage medium) or transmitted via radio frequency unit 801 or network module 802. Microphone 8042 can receive sound and process such sound into audio data.

The ambient light sensor can adjust the brightness of the display panel 8061 according to the ambient light level, and the proximity sensor can turn off the display panel 8061 and / or backlight when the electronic device 800 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used to identify the posture of the electronic device (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. The sensor 805 may also include a fingerprint sensor, pressure sensor, iris sensor, molecular sensor, gyroscope, barometer, hygrometer, thermometer, infrared sensor, etc., which will not be described in detail here.

Specifically, user input unit 807 includes a touch panel 8071 and other input devices 8072. Touch panel 8071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 8071). Touch panel 8071 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 810, which receives and executes commands from the processor 810. In addition, touch panel 8071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. Besides touch panel 8071, user input unit 807 may also include other input devices 8072.

[0131] Furthermore, the touch panel 8071 can cover the display panel 8061. When the touch panel 8071 detects a touch operation on or near it, it transmits the information to the processor 810 to determine the type of touch event. Subsequently, the processor 810 provides corresponding visual output on the display panel 8061 based on the type of touch event. Although in Figure 8 In this embodiment, the touch panel 8071 and the display panel 8061 are two independent components to realize the input and output functions of the electronic device. However, in some embodiments, the touch panel 8071 and the display panel 8061 can be integrated to realize the input and output functions of the electronic device.
