Detailed Description
The present invention will be described below based on examples, but the present invention is not limited to only these examples. In the following detailed description of the present invention, certain specific details are set forth. It will be apparent to one skilled in the art that the present invention may be practiced without these specific details. Well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.
Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.
Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".
In the description of the present invention, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
Common communication systems include satellite communication systems, internet communication systems, and 5G data channels.
Furthermore, the satellite communication system is composed of a satellite end, a ground end and a user end. The satellite end plays the role of a relay station in the air, namely, the electromagnetic wave transmitted by the ground station is amplified and then returned to another ground station. The ground station is the interface between the satellite system and the ground public network, and the ground user can enter and exit the satellite system to form a link through the ground station. The user terminal is a variety of user terminals. The satellite communication system scholaya (Thuraya) satellite communication system, the beidou satellite communication system, the maritime (Inmarsat) satellite communication system and the like.
Further, the internet communication system can be classified into an electronic mail system and an instant messaging system according to the communication manner.
Further, the 5G data channel includes a new broadband access system provided for mobile communication operators.
In general, terminals in different communication systems are not capable of communication. For example, the satellite communication systems operate independently and are not compatible with each other, and do not provide a mutual transfer service, so that information intercommunication between different satellite systems cannot be realized. Meanwhile, the information intercommunication function between the satellite communication system and the e-mail system only has the service from Thuraya short message to e-mail, which is proposed by Thuraya, and the service is unidirectional and does not support bidirectional intercommunication. Moreover, the common instant messaging system and the e-mail often have no function of information intercommunication.
However, a plurality of satellite communication systems coexist, and there is a very vigorous demand for interworking between different satellite communication systems due to differences in coverage areas. Secondly, with the popularization of mobile internet, the instant messaging tool becomes a main daily information communication tool, and for users in areas without coverage of internet and mobile communication network (special environments such as high altitude in the sea of gobi in the island of mountain, desert, etc.), if the users need to communicate with the users using the instant messaging tool of mobile internet by using a satellite communication tool, it is very difficult due to the difference of communication systems.
Therefore, the interconnection of the communication systems plays an important role.

Further, the differential reference station and the high-precision positioning terminal can be realized by special hardware equipment or an intelligent terminal carrying a special application program.

In another optional implementation manner, when the sender user sends information, the communication system type and corresponding address information of the target user are added to the high-precision positioning terminal identifier, and the differential routing server processes the information to be sent to obtain the high-precision positioning terminal identifier therein, so as to determine the available communication system type and address information in the communication system.
Meanwhile, the differential routing server can process the information to be sent to obtain the differential corrected message and store the differential corrected message in the database.
And S250, sending the difference correction message to a corresponding communication system according to the determined communication system type available for the high-precision positioning terminal and the address information of the high-precision positioning terminal in the communication system.
And step S260, the communication system forwards the differential correction message to the corresponding high-precision positioning terminal.
In the embodiment, the differential routing server is connected with the plurality of communication systems, so that the differential reference station sends information to be sent to the differential routing server through the available communication systems, and then the differential routing server selects one or more available communication systems of the high-precision positioning terminals to send the differential correction message to the high-precision positioning terminals. Therefore, users of different application terminals can effectively perform differential calculation, and reliability and convenience of differential calculation can be improved.
Fig. 3 is a flowchart of a difference correction information acquisition method according to an embodiment of the present invention. As shown in fig. 3, the method for acquiring difference correction information according to the embodiment of the present invention includes the following steps:
and S310, receiving information to be sent by the differential reference station, wherein the information to be sent comprises a differential correction message and a high-precision positioning terminal identifier.
In this embodiment, the high-precision positioning terminal acquires information to be transmitted, where the information to be transmitted includes a differential correction message and a high-precision positioning terminal identifier. Specifically, the differential correction message may be differential correction number information supported by any one of standards. The high-precision positioning terminal identifier represents address information of a target user (a user of the high-precision positioning terminal), and in an optional implementation manner, the high-precision positioning terminal identifier is a personal account number or a mobile phone number of the target user.
Further, the differential reference station and the high-precision positioning terminal can be realized by special hardware equipment or an intelligent terminal carrying a special application program.
And S320, determining the type of the communication system available for the high-precision positioning terminal and the address information of the high-precision positioning terminal in the communication system according to the high-precision positioning terminal identification.
In an optional implementation manner, the differential routing server processes information to be sent to obtain a high-precision positioning terminal identifier therein, obtains a personal account of a target user according to the high-precision positioning terminal identifier, and searches accounts or mobile phone numbers bound with the personal account in other communication systems in the differential routing server, so that an available communication system type can be determined, and further address information in the communication system can be determined.
In another optional implementation manner, when the sender user sends information, the communication system type and corresponding address information of the target user are added to the high-precision positioning terminal identifier, and the differential routing server processes the information to be sent to obtain the high-precision positioning terminal identifier therein, so as to determine the available communication system type and address information in the communication system.
And step S330, analyzing the information to be sent, converting the information into a preset format and storing the information in a database.
Step S340, selecting at least one communication interface of available communication system type according to the communication system type of the high-precision positioning terminal and the address information of the high-precision positioning terminal in the communication system, and sending the differential correction telegraph text in the database.
Therefore, the difference calculation can be effectively carried out by the user of the application terminal.
In this embodiment, after receiving the information to be transmitted, the differential routing server parses and converts the information to be transmitted into a predetermined format, and stores the format in the database for convenient calling.
Specifically, fig. 4 is a flowchart of information processing of an embodiment of the present invention. As shown in fig. 4, the steps of parsing the information to be transmitted, converting the information into a predetermined format, and storing the format in the database include:
and step S410, determining the communication system type of the differential reference station according to the differential reference station identifier.
In the embodiment, the method is used for adding the communication system type to the information to be transmitted when the information to be transmitted is added, so that the differential routing server can analyze the information to be transmitted to acquire the communication system type of the differential reference station.
Alternatively, the differential routing server may obtain the communication system type of the differential reference station by reading the interface type of the received information to be transmitted.
Step S420, determining the calculation mode of parsing and converting into a predetermined format according to the communication system type of the differential reference station.
Further, since transmission modes of different types of communication systems are different, that is, signals of different types of communication systems are different, processing methods for the signals are different.
