Description

Technical Field

[0001] The present application relates to the technical field of communication fusion, and in particular to a multi-link communication fusion scheduling system. Background Art

[0002] At present, field operations of special operations teams of troops usually involve many factors, including mobile soldiers, mobile combat vehicles, drones, forward command posts, remote dispatching command centers, etc., which require networking and communication between front-end soldiers, teams, vehicles, unmanned aerial vehicles, forward command posts and back-end combat command centers through 4G / 5G public networks of operators such as China Telecom, China Unicom, and China Mobile, WIFI, wired networks, LTE private networks, satellites, MESH self-organizing networks, etc., and the collected audio, video, images and other information must be quickly, comprehensively and effectively transmitted to the remote combat command center, so that commanders can view the location, analyze and judge, dispatch and command, and issue commands for various information data. Front-end soldiers and vehicles can obtain superior instructions in a timely and accurate manner, and can conduct multi-party audio and video calls, conference consultations, and cluster intercoms.

[0003] At present, the combat environment of special operations teams is characterized by complexity, uncertainty, and multiple coordinated departments. The communication means used by command centers and on-site personnel at all levels are diverse and independent of each other. The main combat equipment in actual combat has the problems of single communication means for individual soldiers and vehicles, single transmission links, and difficulty in integrating multiple networks. For example, it is difficult to integrate multiple networks such as public networks, satellites, and private networks, and it is difficult to transmit multiple links synchronously. There is a lack of integration technology for the integration, sharing, and rapid switching of multiple network communications, and the ability to self-organize and synchronously transmit between multiple different communication networks.

[0004] The combat vehicles are only equipped with on-board satellite stations and on-board radio stations. There is no effective intercommunication between different networks. At the same time, there are problems such as "no signal when someone is there" in some areas. The front-end audio and video images cannot be transmitted to the command center quickly and in a timely manner. The commander has no on-site process images and can only rely on combat documents or telephone reports to perceive and judge. He cannot make efficient decisions based on the real-time situation on the scene, which makes it difficult for the front and rear command and communication. The front and rear command centers lack cross-platform visual collaborative consultation methods and lack collaborative research and command decision-making capabilities. Problems such as difficulty in intercommunication, efficient command, and rapid coordination make the integrated combat of special operations teams still have a certain gap from the requirements of fast and flat command.

[0005] To sum up, the existing technologies such as poor integration of various different networks and effective transmission of multiple types of data information across networks cannot meet the current requirements of special operations forces, which to a certain extent restricts the improvement of the combat effectiveness of the troops and the command interconnection effect. There is a lack of a communication platform to integrate various communication terminals and networks, and a lack of command and dispatch means to perform one-click dispatch of audio and video resources.
