Abstract

The invention discloses a wireless subnet heterogeneous interconnection method, which comprises the following steps of: configuring basic information of an integrated service gateway of each node in a shore base, a target ship and a buoy, so that the integrated service gateway of each node establishes communication connection with a public cloud server through a corresponding 4G router; the public cloud server receives a reachability detection message periodically sent by the integrated service gateway of each node to obtain corresponding 4G reachability information, and obtains a public network address and a port number mapped by the NAT device; and the public cloud server periodically pushes the corresponding 4G reachable information to each node, and informs the corresponding integrated service gateway of the public network address and the port number. The problems that the communication distance suitable for an existing wireless subnet is short, and in the communication process, SIP signaling and media streams fail to traverse NAT equipment and NAT mapping are solved.

Description

technical field [0001] The invention relates to the technical field of smart ocean wireless communication, in particular to a heterogeneous interconnection method of wireless subnets and a heterogeneous interconnection system of wireless subnets. Background technique [0002] With the country's increasing emphasis on "smart ocean", "smart ocean" has ushered in the best time for rapid development. Facing the new demand for smart ocean emergency communication test network construction, the wireless communication system needs to integrate 4G network, LTE private network and other communication means to realize the business access between the shore-based comprehensive control system and emergency support ships and buoys, and ensure the shore-based command center, Emergency communication guarantees wireless communication between ships and buoys. The system carries application services based on standard IP data packets, and builds an IP network with end-to-end addressing and rout...
