Abstract

The invention discloses a constellation satellite system and a communication method and system based on the same. The constellation satellite system comprises terminals, constellation satellites, a gateway station, and a cluster core network. The terminals comprise various types of cluster user terminals. The constellation satellites comprise a plurality of LEO (low earth orbit) or MEO (medium earth orbit) satellites which cover the whole globe, and the constellation satellites form a constellation. The gateway station is used for completing the access of the network of the constellation satellites to the cluster core network. The cluster core network comprises a cluster user group, the registration of the group members, the discrimination of the authority of the users and business, the call processing, the charging management and the scheduling management. The cluster corn network irons out the defects of ground wireless cluster communication, and a global wireless cluster network transmission trunk line is built through a constellation satellite mobile communication network, and the emergency command communication capability of a wireless cluster is effectively extended. Meanwhile, the constellation satellite system is good in emergency adaptability, convenience and economical performances.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a constellation satellite system, a communication method and system based on the constellation satellite system. Background technique [0002] Ground digital trunking communication system is a main form of emergency communication and dispatching communication. At present, it is gradually developing from traditional voice dispatching-based narrowband communication to broadband. The main digital trunking communication systems used include TETRA, iDEN, GoTa, GT800, McWILL and McLTE et al. [0003] The ground digital trunking communication network has tended to be perfect, but due to geographical conditions, seamless global coverage cannot be achieved. In the vast sea area 20 kilometers away from the coastline, in the air, in the large desert or jungle area in the middle of the land, and at ultra-high altitude mountains, etc. In special regions, a...
