Network access method, device and system for marine ship equipment

Abstract

The invention discloses a network access method, device and system for marine ship equipment. The method comprises the steps: receiving a network access instruction which is used for controlling to-be-accessed target ship equipment to carry out network connection; in response to the network access instruction, obtaining a network signal searched by the target ship equipment; determining a signal transmitting device corresponding to the network signal and first device network access information of the signal transmitting device based on the network signal; and under the condition that the first equipment network access information is used for indicating that the signal transmitting equipment is currently accessible, accessing the signal transmitting equipment according to a network access operation corresponding to the signal transmitting equipment so as to establish a network communication link between the target ship equipment and the signal transmitting equipment. According to the invention, different network access strategies are adopted for different signal transmitting devices such as a shore-based base station or the first ship device, the ship devices on the sea surface can be guaranteed to access the network in batches, and the networking success rate of the ocean ship devices can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of ship communication, in particular to a network access method, device and system for marine ship equipment. Background technique [0002] All ships on the sea surface are communication nodes, and the distribution is distinct, such as Figure 5 shown. The number of ships near the coast is large and densely distributed, and most of them are civilian transport ships; the number of ships on the far coast is small and sparsely distributed, and most of them are fishing boats, large oil tankers, and military ships. Most of the existing maritime wireless communication methods are shore-based mobile communication and satellite communication. However, the coverage of shore-based base stations is limited (<110km). In order to ensure that the received signal can be successfully decoded, user terminals can only access base stations with a distance of less than 110km as the basis. Communication guarantee, ...

Problems solved by technology

Most of the existing maritime wireless communication methods are shore-based mobile communication and satellite communication. However, the coverage of shore-based base stations is limited (<110km). In order to ensure that the received signal can be successfully decoded, user terminals can only access base stations with a distance of less than 110km as the basis. Communication guarantee, when the number of access user terminals is too large, the access distance will become smaller

However, the coverage of satellite communication involves most of the open sea, but its bandwidth is limited, the delay is too long and the network access fee is high, which limits its wide use
