Abstract

The present invention relates to an interaction method between space network and ground network and a communication protocol gateway. The interaction method comprises the following steps: monitoring and receiving network transmission package by the communication protocol gateways which are connected with one another through a distribution mode based on internet through a local main channel; identifying the style of transmission network of network transmission package, allocating the network transmission packages to the space-ground subchannel, ground-space subchannel, space-space subchannel or ground-ground subchannel according to the style of transmission network; transmitting the network transmission packages after executing protocol conversion to the network transmission packages by the space-ground subchannel and ground-space subchannel; and transmitting the network transmission packages after processing the network transmission packages by the space-space subchannel and ground-ground subchannel. The communication protocol gateway comprises a main channel, the space-ground subchannel, the ground-space subchannel, the ground-ground subchannel and space-space subchannel. The invention adopts the communication protocol gateway for converting protocol. The convenient interaction between the space network and the ground network can be realized. Each network transmission package is processed with the channel form. The processing efficiency can be increased and the generation of data transmission bottleneck is prevented.

Description

technical field [0001] The invention relates to communication technology, in particular to an interaction method between a space network and a ground network and a communication protocol gateway. Background technique [0002] In recent years, the mobile communication network has gradually transitioned to be composed of multiple heterogeneous networks covering each other, and various heterogeneous networks can be divided into two types: space network and ground network. Space network refers to a network formed by space communication technology, such as a satellite network, and a mobile ad hoc network composed of spacecraft, space stations, space shuttles, space planes and other spacecraft interconnected through space links; ground network refers to Networks formed using terrestrial communication technologies, such as cellular networks, mobile ad hoc networks composed of mobile hosts, Worldwide Interoperability for Microwave Access (hereinafter referred to as: WiMAX) networks ...
