The organization of this article is as follows: We first introduce the architecture of integrated satellites with 5G/6G networks . Then, we ...
With the expansive deployment of ground base stations, low Earth orbit (LEO) satellites , and aerial platforms such as unmanned aerial vehicles (UAVs) and high altitude platforms (HAPs), the concept of space-air-ground integrated network (SAGIN) has emerged as a promising architecture for future 6G wireless systems. In general, SAGIN aims to amalgamate terrestrial nodes, aerial platforms, and ...
Integrated satellite -terrestrial networks (ISTNs) have recently been considered a key enabler for global wireless services in 6G [5]. The ISTN architecture leverages and combines the differ-ent, featured strengths of satellite and terrestrial networks to provide universal connections for various services with diverse requirements.

II. SATELLITE NETWORK SYSTEM ARCHITECTURE The structure of the satellite network is shown in Fig. 1. The model is divided into three layers from top to bottom according to altitude: the geostationary orbit (GEO)/medium Earth Orbit (MEO) layer, the LEO layer where the satellites communicate with each other by ISLs, and the Earth layer.
A review of technological solutions and advances in the framework of a Vertical Heterogeneous Network (VHetNet) integrating satellite , airborne and terrestrial networks is presented. The disruptive features and challenges offered by a fruitful cooperation among these segments within a ubiquitous and seamless wireless connectivity are described. The available technologies and the key research ...
NTN Overview
Constellation routing is a routing decision method for inter-satellite communication technology ( Inter-Satellite Link, ISL) used in dynamically changing but periodically predictable satellite subnetworks. Its goal is to ensure high performance and reliability in message transmission while minimizing network delay and packet loss rates.
Example of a VHetNet scenario by considering some space, air and ground network components as envisioned in 6G wireless communications.
