The narrowband satellite communication system 11 comprises a circuit board card and a passive antenna 112; the passive antenna 112 is installed on the surface of the base 101; the circuit board card is installed inside the base 101, and the drawing is not shown. And the circuit board card is provided with electronic components such as a memory, a processor and the like.
The high-density energy battery is integrated in the base 101 and used for supplying power to the integrated satellite communication terminal and is convenient to use in the field operation scene.
The portable wide-narrow band integrated satellite communication terminal has the advantages of being simple to use, high in reliability and diversified in functions, and meeting practical use requirements.
In one embodiment, the method further comprises: the router is used for providing a wireless local area network so that a user can carry out interface configuration on the converged satellite communication terminal through the wireless network by using an application program on the mobile terminal;

For example, refer to the schematic structural diagram of another portable broadband and narrowband converged satellite communication terminal shown in fig. 3; the converged satellite communication terminal mainly comprises: the system comprises a broadband satellite communication system, a narrowband satellite communication system, a router and a power supply module;
it is worth emphasizing that the broadband satellite communication system comprises a Ka satellite antenna system and a satellite modem;
the narrow-band satellite communication system comprises an antenna communication module and an antenna, wherein the antenna communication module is integrated in the box body 111;
the ka satellite antenna system comprises modules such as an antenna controller and the like, and is further provided with a one-key satellite-alignment key, a liquid crystal display screen and a state indicator lamp.
The heaven communication module is connected with a LAN port of the router through an RJ45 interface. The other LAN port of the router is connected to a broadband satellite communication system. When the portable wide-band and narrow-band integrated satellite communication terminal is used, a matched mobile phone application program APP is required. The WAN mouth of router passes through the net twine and is connected with satellite modem's LAN mouth, and the radio frequency interface connection wiFi antenna of router launches the wiFi signal, and user's cell-phone installation APP connects wiFi, can realize pronunciation and SMS conversation, monitoring information passback and remote operation configuration function through APP operation interface.
The method for using the portable broadband and narrowband converged satellite communication terminal is described in detail below.
After the portable wide-band and narrow-band integrated satellite communication terminal is started, a one-key satellite alignment key is pressed, satellite alignment on-line is automatically completed, and a Wi-Fi hotspot for accessing external equipment (such as a mobile phone) is provided.
And video acquisition equipment such as a user mobile phone or a control ball is connected with a Wi-Fi hotspot provided by the converged satellite communication terminal, and a high-speed satellite communication link is established with the command center to realize high-definition video transmission. By means of an APP visual operation interface, narrow-band voice and short message communication and remote monitoring functions are achieved.
And the user opens the special APP of the mobile phone, inputs the called number, performs dialing operation and waits for the connection of the called user. And the call request is pushed to the high-priority user according to the priority setting.
The user can apply for the switching priority to the converged satellite communication terminal through the permission switching key of the APP. When the low-priority users apply for the use right, the converged satellite communication terminal checks the priority of all the current connected users, and if all the low-priority users are low-priority users, the converged satellite communication terminal directly allocates high priority. If the high-priority user exists, the converged satellite communication terminal sends permission application release information, and after the user releases permission, the applicant can have the high priority. However, only one user mobile phone can realize the narrowband voice function at the same time, when one user mobile phone performs narrowband voice service, the other user mobile phones need to wait for the narrowband voice service to be idle to perform service.
The user can edit and check the short message by using the mobile phone APP, and multiple mobile phones of the user can receive and send the short message at the same time.
The state monitoring and log information of the broadband satellite communication system is transmitted back to the satellite master station through a narrow-band short message or a data link, automatic timing transmission or manual transmission according to needs is supported, and the behavior is selected by a user in an APP. The satellite master station can send a remote control instruction to the converged satellite communication terminal through a narrow-band short message or a data link, and the functions of parameter configuration, restarting and the like of the portable wide-band and narrow-band converged satellite communication terminal are realized.
A user can enjoy the Ka broadband satellite communication network and the heaven-earth communication network simultaneously by purchasing a set of portable broadband and narrowband integrated satellite communication terminal equipment, so that the occupied equipment space can be saved, and the investment of the user on engineering and operation and maintenance is reduced. When the Ka broadband satellite communication system cannot normally carry out satellite online, the heaven-through narrowband satellite communication system is used for carrying out backup communication, so that the communication link and the operation step of a user can be omitted, and the problem solving efficiency is improved. Meanwhile, the satellite master station can collect and master equipment fault log information at the first time, and the establishment of a product problem library is facilitated.
According to a second aspect of the embodiments of the present invention, the present application further provides a method for wideband-narrowband converged satellite communication, where the method includes:
step S301, a broadband satellite communication system establishes broadband connection with a communication opposite terminal, establishes a first communication link, and transmits broadband data through the first communication link; step S302, a narrow-band satellite communication system establishes narrow-band connection with a communication opposite terminal, establishes a second communication link, and transmits narrow-band data through the second communication link; step S303, if the first communication link is interrupted and the broadband satellite communication system cannot mutually transmit the video data with the opposite communication terminal, the narrowband satellite communication system is used for mutually transmitting the voice data with the opposite communication terminal through the second communication link.
In one embodiment, in operation, a narrowband satellite communication system obtains log data and device monitoring data of the broadband satellite communication system; and sending the log data and the equipment monitoring data to a satellite main station through a second communication link.
In one embodiment, the frequency band used by the narrowband satellite communication system is an S-band; and if the first communication link is interrupted due to extreme weather, the second communication link of the narrow-band satellite communication system is used for carrying out voice data intercommunication with the opposite communication terminal.
In one embodiment, the narrowband satellite communication system receives a user beam update parameter transmitted by a satellite master station through a second communication link; and sending the updated parameters to the broadband satellite communication system so that the broadband satellite communication system updates the satellite antenna system and the satellite modem.
In one embodiment, after receiving log data and device monitoring data of the broadband satellite communication system, which are sent by the narrowband satellite communication system through the second communication link, the satellite master station updates the locally stored converged satellite communication terminal database according to the identifier of the converged satellite communication terminal.
In one embodiment, when a call is made through the narrowband satellite communication system, a user inputs a called number into an application page on the mobile terminal to perform dialing operation, and waits for the called user to be connected.
In one embodiment, when voice data is transmitted to a correspondent node by using a second communication link, if an incoming call request of a user of the correspondent node is received, the incoming call request is pushed to a local high-priority user according to a preset priority.
Specifically, priority switching can also be performed, when a low-priority user applies for a use right, the convergence satellite communication terminal checks the priorities of all current connection users, and if all the low-priority users apply for the use right, the convergence satellite communication terminal directly allocates a high priority;
if the high-priority user exists, the converged satellite communication terminal sends permission application release information, and after the user releases permission, the applicant can have the high priority.
Illustratively, if there is no group leader in a rescue team, then all are low priority. If someone in the group applies for high priority, the user is directly given high priority, group leader level.
If there is already a group leader and there are other users in the group applying for the group leader, the priority of the group leader needs to be adjusted down first, and then the priority of the user needs to be adjusted up.
Preferably, the differentiated setting may be formed by setting a plurality of different high and low levels according to the level of the priority. For example, in a rescue team, the called priority of the mobile phone number of each member can be set from high to low in sequence. When the called party is called, if the calling time of the called number exceeds the preset time period threshold value and no one answers, the next low-level number is automatically switched to answer.
The time period threshold may be flexibly set, for example, to 15 seconds, and the application is not limited thereto.
In one embodiment, when an incoming call from a correspondent terminal is received through the narrowband satellite communication system, the incoming call is pushed to a high-priority user according to a priority setting performed in advance.
Illustratively, in a rescue team, the team leader has the highest priority and the team members have lower priorities. Therefore, the priority of the telephone number of the small group leader is set to be the highest, and when the incoming call is received through the narrow-band satellite communication system, the mobile phone number of the small group leader is pushed to carry out answering on the incoming call in a limited way.
In one implementation mode, when an authority application sent by a user is received, whether the authority of the user is a low-priority authority is judged; if yes, checking the priority authorities of all users; and if the priority authorities of all the users are all the low priority authorities, allocating the high priority authority to the users.
Specifically, an authority switching key is arranged on an application program on a mobile terminal of a user; the user can apply for the switching priority from the converged satellite communication terminal through the authority switching key. If the high-priority user exists, the converged satellite communication terminal sends permission application release information, and after the user releases permission, the applicant can have the high priority.
However, only one user mobile phone can realize the narrowband voice function at the same time, when one user mobile phone performs narrowband voice service, the other user mobile phones need to wait for the narrowband voice service to be idle to perform service.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
It will be apparent to those skilled in the art that the modules or steps of the present invention described above may be implemented by a general purpose computing device, they may be centralized on a single computing device or distributed across a network of multiple computing devices, and they may alternatively be implemented by program code executable by a computing device, such that they may be stored in a storage device and executed by a computing device, or fabricated separately as individual integrated circuit modules, or fabricated as a single integrated circuit module from multiple modules or steps. Thus, the present invention is not limited to any specific combination of hardware and software.
