Description

A geographical location reporting method based on satellite short data

Technical field

The invention relates to a geographical location reporting method, specifically a geographical location reporting method based on satellite short data, and belongs to the technical field of satellite communication.

Background technique

Guangdong is also a province prone to natural disasters. Emergency communication support also requires standardized construction and deployment by Guangdong Telecom and the Emergency Department. When spontaneous combustion disasters occur or the emergency lifesaving public network is powered off, satellite terminal rescue needs to be able to locate in real time.

Technical status and corresponding defects:

1) When the public network base station is powered off, the ground communication terminal loses its signal and cannot perform positioning or communication;

2) Natural disasters cause network and power outages, and terminal positioning is lost, making it impossible to implement emergency rescue dispatch;

3) When the public network is disconnected and the power is lost, the village-to-village command function cannot be realized;

4) There are no relevant technical means for marine fishery vessel management.

Contents of the invention

The purpose of the present invention is to provide a geographical location reporting method based on satellite short data in order to solve the problem, so that when there is no public network, the Tiantong satellite communication link can be used for location reporting, and real-time location reporting of personnel can be realized. And tracking, support personnel and command center positioning are both online and never lose contact.

The present invention achieves the above objects through the following technical solutions: a geographical location reporting method based on satellite short data, including the following steps:

Step 1. The satellite is connected to the network, and the terminal is connected to the network in an open and unobstructed outdoor environment;

Step 2: Open the SMS gateway, and insert the terrestrial network card used to receive encrypted SMS messages into the SMS gateway;

Step 3: After the terminal connects to the network, it obtains the location report and sets the reporting time;

Step 4: After obtaining the positioning, the terminal automatically generates an encrypted text message, and the terminal sends the encrypted text message;

Step 5: The SMS gateway receives the encrypted SMS and parses the encrypted SMS.

As a further solution of the present invention: in the third step, the terminal uses Tiantong customization to obtain the location, and the location platform obtains the terminal SMS file from the issued instructions and analyzes the time, geographical location and other contents in the bill file to provide batch User location reporting and individual user real-time location reporting.

As a further solution of the present invention: in the third step, the terminal defines the network management interface according to the UTRAD methodology, and the communication protocol of the interface uses the http protocol and json format to transmit data.

As a further solution of the present invention: in step three, when performing location reporting, the following scenarios are included:

① After the public network goes offline, the satellite network connection will be automatically reported;

②Report the satellite network access interval;

③The satellite ground dual-network access terminal actively reports.

As a further solution of the present invention: in step four, the signature rules for the terminal to obtain permission are as follows:

Users need to use password+uuid, and finally combine it into a string;

The digest generated using [MD5Util.getMD5String(password+uuid)] encryption method is the data signature and placed in the token field.

The beneficial effects of the present invention are:

1) The terminal uses the satellite link to send the terminal positioning report to the platform through SMS, realizing the positioning service combining Tiantong and the ground network; the satellite terminal accesses the network through Tiantong satellite and obtains positioning, and can report the position at any time to determine its position information and maintain it. Satellite communication is smooth, ensuring that the terminal can achieve the function of maintaining communication and providing nearby rescue in case of network and power outage;

2) Satellite terminals access the network through Tiantong positioning. The command and dispatch console can locate the location through the terminal report, determine the geographical location of the disaster area and implement rescue or command and dispatch; the satellite terminal reports the position, and the command and dispatch console can see the terminal location information and know it. When the terminal is online, the command and dispatch station can report the geographical location through the terminal for unified dispatch, realizing multi-person cluster emergency rescue dispatch, ensuring that emergency communications in multiple places and villages are not lost and emergency dispatch can be carried out;

3) Through position reporting, satellite terminals can determine the position of ships at any time and issue warnings to ships; such as cross-border warnings heading to other countries' waters, emergency disaster typhoon warnings, ship entry and exit warnings, return warnings, etc.; terminal positioning information is encrypted and sent through Tiantong Chain The positioning accuracy is high and the location information is encrypted and secure; the Tiantong satellite network and ground network positioning services are combined and switched accurately.

Embodiment 3

A geographical location reporting method based on satellite short data, taking the Tiantong-1 satellite mobile communication system as an example. This system is currently in the commercial operation stage. With the launch of Tiantong-1 02 and 03 satellites, it has realized overseas area coverage. After applying the present invention, it can be ensured that customers can timely grasp the geographical location of their users, especially user terminals in a large range, and can effectively improve emergency communication command, dispatch and processing capabilities. The details are as follows: 1) The location tracking system initiates the standard positioning process - the terminal actively reports positioning; 2) the location tracking system initiates the standard positioning process - single positioning; 3) The terminal initiates a single positioning command by actively reporting the position or in the background. Determine the terminal positioning time, geographical location, satellite number, and perform alarm, command and dispatch functions for the terminal.

Working principle: When a satellite mobile communication terminal initiates a service (satellite access to the network), the core network obtains the relevant information of the UE location (the longitude and latitude of the satellite user) from the access network GSC according to the Iu interface specified by 3GPP. The core network then sends the obtained location information to other network elements (location service platform) through the short data interface.
