At present, there are VTS centers in the main coastal ports of our country and some important inland river sections, which can use traditional radar, AIS (Automatic Identification System, automatic identification system for ships) and CCTV (Closed Circuit Television, closed-circuit television) to monitor ships, and through VHF (Very High Frequency, VHF) method provides traffic management and navigation information services for navigable ships. These VTS centers have played a huge role in ensuring ship traffic safety, improving traffic efficiency, and protecting the water environment, but there are still some shortcomings:

1) The coverage of VTS is limited, especially in the inland rivers of our country, there are still many river sections in VTS blind spots. Some of these river sections have a large flow of ships, complex water traffic, and some operate a large number of dangerous goods ships, which have huge hidden dangers to navigation safety .

2) The communication between the VTS center and the ship is mainly through VHF, the service method is single, the content is limited, and there are problems such as uneven quality of supervisory personnel, non-standard and non-standard communication terms, and serious local accents.

In recent years, with the rapid development of mobile communication technology, 3G (3rd-Generation, third-generation mobile communication technology) and even 4G (the 4th Generation mobile communication technology, fourth-generation mobile communication technology) have been fully promoted and popularized in my country. . Moreover, the hardware and operating system of mobile devices (smart phones or tablet computers) have already possessed capabilities comparable to those of PCs, and have become the preferred devices for people's online shopping, office and other applications. It can be said that the mobile Internet is changing the way people live and work.

The VTS system of the mobile traffic control station is a VTS system installed on the patrol ship of the Maritime Safety Administration. It is mainly used to supervise and manage the ships entering and leaving the voyage during the heavy traffic period in specific waters, so as to realize the orderly passage of ships and avoid traffic accidents. The mobile traffic control VTS system can provide information services to ships in the managed waters, but its service methods are mainly AIS short messages and GSM (Global System for Mobile Communication)/CDMA (Code Division Multiple Access, Code Division Multiple Access) address) SMS function. For AIS ships, the text information service can be provided through the broadcasting and directional sending short message functions of the AIS equipment. The text information only supports English and does not support Chinese. For ships bound with a SIM card, text messages can be sent through the SMS function. On the whole, the information service function for ships is limited to text information, and the capacity is very limited.
