Abstract
Description
Technical Field
[0001] This utility model belongs to the field of converged communication technology, and specifically relates to a converged communication device. Background Technology
[0002] Existing mobile communication devices face the risk of connection interruption in areas with weak mobile signal coverage (such as remote areas and disaster scenarios), while a single satellite communication mode is costly and cannot meet users' security requirements for dedicated networks. In traditional technologies, switching between mobile and satellite communication relies on manual operation, lacks intelligent decision-making logic, and does not provide on-demand access to dedicated satellite networks.
[0003] Patent document 1 (CN115065403A) provides a method based on pre-set network priority rules to control a network switching switch to perform a two-way switching operation, enabling the user's mobile terminal to access the terrestrial telecom operator's network / Internet via the satellite antenna or 4G / 5G router for telephone / Internet communication. This achieves the purpose of using satellite communication networks to "fill in the gaps," supplement, or extend terrestrial mobile communication networks. However, this patent document lacks specific switching determination rules, relying solely on the presence or absence of 4G / 5G signals to determine whether to perform a network switch. This simple and crude determination mechanism cannot guarantee the quality of network access for the terminal. Furthermore, its satellite communication can only access public satellite communication networks, failing to meet diverse customer needs and unable to achieve highly secure access to dedicated satellite networks.
[0004] Patent document 2 (CN118804180A) provides a method for switching between a satellite network and a mobile communication network. It detects whether the current mobile communication network signal meets the switching conditions based on the RSSI strength parameter and uses a threshold for comparison and determination. The determination logic is also simple and cannot guarantee that the channel switching will be completed at the appropriate time to ensure the network quality of the terminal.
[0005] Therefore, considering that satellite communication has the advantages of wide coverage, no limitation by ground infrastructure, applicability to remote areas, high reliability, and support for mobility, how to provide a ground access terminal that integrates mobile communication and satellite communication, so as to cover areas that terrestrial networks cannot reach, such as oceans, deserts, and polar regions, without relying on ground infrastructure, including voice, data, video, and Internet of Things (NB-IoT) transmission; and at the same time meet the access needs of users' emergency dedicated satellite communication networks, is an urgent problem that technical personnel need to solve. Utility Model Content
[0006] This invention provides a device and implementation equipment that integrates mobile communication and satellite communication, which enables access to a highly secure dedicated satellite network while ensuring the quality of satellite communication terminal network access signals.
[0007] In a first aspect, this utility model provides a device integrating mobile communication and satellite communication, comprising: a base station, a network interface unit, a network switch, a mobile communication router, a first modulation and demodulation module, a second modulation and demodulation module, a satellite antenna, and a control module;

[0014] The network interface unit also includes a control port. The control module is connected to the control port of the network interface unit and is used to control the establishment of connections between the network interface unit and the base station and network switch.
[0015] The network interface unit also includes a third network interface, which is a WAN interface, and external devices are connected to the third network interface.
[0016] The control module completes the connection between the second network interface and the fourth network interface based on control commands; the control module completes the connection between the fourth network interface and the first satellite communication interface, or the connection between the fourth network interface and the second satellite communication interface, or the connection between the fourth network interface and the mobile communication network interface based on control commands.
[0017] Secondly, this utility model provides an implementation device for a converged mobile communication and satellite communication device, including a housing and the aforementioned converged mobile communication and satellite communication device encapsulated within the housing.
[0018] The beneficial effects of this utility model are as follows: The device of this utility model integrates mobile communication and satellite communication. In view of the situation where the signal quality of mobile communication network is poor in remote areas, the satellite communication network can be used as a user terminal access method on the one hand; on the other hand, it can be used to simultaneously access the mobile communication network and the satellite communication network, thereby realizing the fusion of the mobile communication network signal and the satellite communication network signal, improving the access bandwidth of the user terminal, and ensuring the user's Internet access speed.
[0019] In practical applications, the signal quality index (SQI) can also be calculated by comparing the signal quality of the mobile communication router signal and the satellite communication signal, combined with the signal-to-noise ratio (SNR) and bit error rate (BER). When the SQI is lower than a preset threshold (such as -90 dBm equivalent), the switch to the satellite communication interface is triggered.
[0020] Users can also choose whether to switch to the first satellite communication interface based on actual costs; if the user actively enables the dedicated satellite communication network, then switch to the second satellite communication interface.
[0021] Furthermore, this invention also designs a weighted summation factor based on SQI and (power consumption / battery balance) to determine the quality of mobile communication signals and public network satellite communication signals, so that switching can be completed even when the battery power is low.

[0029] To facilitate understanding of the technical content of this utility model by those skilled in the art, the content of this utility model will be further explained below with reference to the accompanying drawings.
[0030] Example 1
[0031] like Figure 1 As shown, the device for integrating mobile and satellite communication provided by this utility model includes: a base station, a network interface unit, a network switch, a router, a first modem module, a second modem module, a satellite antenna, and a control module. The network interface unit has a first control interface, a second control interface, a third control interface, a first network interface, a second network interface, and a third network interface. The network switch has a controlled interface, a fourth network interface, a first satellite communication interface, a second satellite communication interface, and a mobile communication network interface. The network interface unit also includes a control port and a WAN interface; the control module is connected to the control port of the network interface unit; and an RJ45 interface is connected to the WAN interface of the network interface unit.
[0032] like Figure 1 As shown, it also includes a mobile communication router, which connects to the mobile communication network interface of the network switch and the third control interface of the network interface unit.
[0033] in, Figure 1 The control module can be an RF switch used to switch between different satellite communication networks (public and private) when accessing them. The private network is an emergency satellite communication network. The public and private satellite communication networks are multiplexed by the control module (preferably a network multiplexer), connected to the satellite communication antenna, to realize the transmission and reception of satellite communication network signals. The satellite communication network antenna is preferably a planar array antenna, but a phased array antenna can also be used.
[0034] The interface board is a circuit board that provides a variety of interfaces. All control interfaces and all network interfaces are existing interfaces. For example, the control interface may, but is not limited to, use the RS-232 standard interface, and the network interface may, but is not limited to, use the RJ45 network cable interface.
[0035] The signals of the first and second modem modules can be MD6000 and TDA200. The mobile communication router described in this utility model also includes a WIFI module for providing network access to portable devices near the satellite communication terminal.
[0036] The satellite antenna can be a planar waveguide array antenna or a 1024 phased array satellite antenna.
[0037] The specific scenarios in which the above-mentioned device implements communication functions include the following:
[0038] 1. When there is no mobile communication signal but there is a public satellite communication signal, the following functions can be achieved:
[0039] 1) Telephone signals can be transmitted via telephone <-> satellite communication terminal <-> satellite communication operator network <-> Internet <-> terrestrial communication operator network to achieve telephone communication;
[0040] 2) Internet access signal: User devices can access the Internet via mobile phone / laptop / desktop <-> satellite communication terminal <-> Internet;
[0041] 2. When there is no public satellite communication signal but there is a mobile communication signal:
[0042] 1) Telephone signal: Telephone communication can be achieved through telephone <-> base station <-> terrestrial communication operator network;
[0043] 2) Internet access signal: User devices can access the Internet via mobile phone / laptop / desktop computer <-> network management unit <-> mobile communication operator network <-> Internet.
[0044] 3. When there is no mobile communication or public satellite communication signal, or when access to mobile communication / public satellite communication is not required, access to a dedicated satellite communication network is available:
[0045] 1) Telephone signal: Telephone communication via dedicated satellite network can be achieved through telephone <-> satellite communication terminal <-> private satellite communication operator network <-> dedicated satellite network <-> terrestrial dedicated satellite communication operator network;
[0046] 2) Internet signal: User equipment can access the internal local area network via mobile phone / laptop / desktop computer <-> satellite communication terminal <-> dedicated local area network.
[0047] 4. When both mobile communication and public satellite communication signals are poor, or when it is necessary to increase network access bandwidth, converged traffic access of mobile communication and satellite communication can be achieved. That is, data convergence / distribution is achieved through mobile phone / laptop / desktop computer <-> network management unit <-> mobile communication router and satellite communication terminal <-> satellite communication operator network / mobile communication operator network <-> Internet, so that user devices can access the Internet. This can not only ensure the success rate of users accessing the Internet, but also improve the bandwidth of users' access.
[0048] In this invention, the mobile communication router and satellite communication terminal data fusion / distribution, as shown in the text and image data transmission, use the mobile communication and public network satellite communication signals with higher bandwidth to transmit images, and the other to transmit text; if it is long text data, the data is split, and the transmission is also based on the available bandwidth of the two communication methods.
[0049] against Figure 1 The integration of a network management unit (MMU) with a network switch is equivalent to a network management unit, and this MMU can also be deployed in a satellite communication terminal (such as...). Figure 1 The device shown integrates mobile and satellite communications. The operational status information of the mobile communication router can be collected via a third control interface.
[0050] Example 2
[0051] This utility model also provides a device for integrating mobile communication and satellite communication, the device including a housing, and the aforementioned device for integrating mobile communication and satellite communication is encapsulated inside the housing.
[0052] Example 3
[0053] This utility model also provides a method for integrating mobile communication and satellite communication, such as... Figure 2 As shown, the specific steps include:
[0054] S11. The above-mentioned integrated mobile communication and satellite communication device (hereinafter referred to as the device) is powered on and initialized, loading the firmware of each module and entering the initialization interface;
[0055] S12. The device receives input commands from the user;
[0056] User commands can be given to the user on the device's display module ( Figure 1 Touch input is available on the interface (not shown), or it can be switched via the control switch of the device. The instructions include the following options: 1) Mobile communication signal access; 2) Public network satellite communication signal access; 3) Private network satellite communication signal access; 4) Mobile communication and public network satellite communication signal access.
[0057] S13. Based on user input commands, the control module controls the network interface unit and the corresponding network interface in the network switch to establish a connection; specifically: when the input command is 1), the control module controls the fourth network interface to establish a connection with the mobile communication network interface; when the command is 2), the control module controls the first satellite communication interface to establish a connection with the fourth network interface; when the command is 3), the control module controls the second satellite communication interface to establish a connection with the fourth network interface; when the command is 4), the control module controls the fourth network interface, the mobile communication network interface, and the first satellite communication interface to establish a connection simultaneously.
[0058] S14. The device completes access to the corresponding network, such as accessing a mobile communication network / public satellite communication network / dedicated satellite communication network separately, or accessing a mobile communication network and a public satellite communication network in a combined manner.
[0059] S15. The user equipment connects to the device to enable telephone / Internet access functions.
[0060] Example 4
[0061] This embodiment can be understood as a further improvement based on the above-described embodiment two.
[0062] The basis for establishing a connection between the network interface unit and the corresponding network interface in the network switch in step S13 above can be further set as follows: The signal quality index is calculated by weighting the signal-to-noise ratio (SNR) and bit error rate (BER). In this embodiment, the signal quality index is calculated using SQI. When the SQI of the public network satellite communication signal is less than a preset threshold, and the SQI of the mobile communication signal is greater than or equal to a preset threshold (e.g., -90 dBm equivalent), the control module controls the fourth network interface to establish a connection with the mobile communication network interface. When the SQI of the mobile communication signal is less than a preset threshold, and the SQI of the public network satellite communication signal is greater than or equal to a preset threshold, the control module controls the first satellite communication interface to establish a connection with the fourth network interface. When both the SQI of the mobile communication signal and the SQI of the public network satellite communication signal are 0, the control module controls the second satellite communication interface to establish a connection with the fourth network interface. When both the SQI of the mobile communication signal and the SQI of the public network satellite communication signal are greater than 0 and less than a preset threshold, the control module controls the fourth network interface to simultaneously establish connections with the mobile communication network interface and the first satellite communication interface.
[0063] The Signal Quality Index (SQI) is calculated as follows:
[0064]
[0065] Among them, in the above formula These are the weighting coefficients for the signal-to-noise ratio. These are the weighting coefficients for the bit error rate (BER). a1 and a2 can be preset by technicians or obtained through iterative training of the neural network model based on initial values; no specific limitations are imposed here.
[0066] In addition, the signal quality index can preferably be RSSI strength.
[0067] Example 5
[0068] In actual operating environments, considering only the quality of mobile communication signals while ignoring the quality of current satellite communication signals cannot achieve ideal communication functions. Furthermore, due to the differences in satellite communication frequency bands and mobile communication frequency bands, there are differences in system power consumption. How to complete the switching when the battery power of the device described in this utility model is low, while simultaneously meeting the requirements of signal quality and power consumption, is a technical problem that urgently needs to be solved.
[0069] Furthermore, in step S13 above, the basis for establishing a connection between the control module and the corresponding network interface in the network switch can be further set as: network switching factors Ω1 and Ω2 obtained by weighted summation of SQI and (power consumption / battery balance).
[0070]
[0071]
[0072] in, The weighting coefficients are P1 and P2, representing the power of the satellite communication terminal under public network satellite communication signal access and mobile communication signal access, respectively. SOC (state of charge) is the remaining battery power (usually expressed as a percentage), and P0 is the rated battery capacity. Similarly, these weighting coefficients can be preset to fixed values or obtained from initial values using a neural network model. In practical applications, the link corresponding to the larger of Ω1 and Ω2 is selected, i.e., the communication link with the larger network handover factor value in public network satellite communication or mobile communication is selected.
