What is Space-Terrestrial Integrated Networks?
Space-Terrestrial Integrated Networks (STINs) combine satellite and terrestrial communication systems to provide seamless global coverage and enhanced capacity in 5G/6G ecosystems.
STINs address integration of low Earth orbit (LEO) satellites with cellular networks for ubiquitous connectivity (You et al., 2020; 1816 citations). Research covers resource allocation, mobility management, and hybrid architectures (Azari et al., 2022; 504 citations). Over 10 surveys since 2015 analyze NTN evolution with 270-1816 citations each.
Why It Matters
STINs enable coverage in remote areas for IoT and disaster response, as satellite systems support Internet of Remote Things (De Sanctis et al., 2015; 575 citations). They integrate with 5G/6G for global broadband, reducing gaps in terrestrial networks (Kodheli et al., 2020; 1174 citations). Chen et al. (2020; 297 citations) highlight B5G trends where LEO satellites boost capacity in underserved regions.
Key Research Challenges
Seamless Handover Management
High mobility between satellite and terrestrial segments causes frequent handovers, increasing latency (Azari et al., 2022). Rinaldi et al. (2020; 351 citations) note Doppler shifts in NTNs complicate 5G integration. Solutions require adaptive protocols for uninterrupted service.
Resource Allocation Optimization
Dynamic spectrum sharing between space and ground networks faces interference issues (Chen et al., 2020). You et al. (2020; 1816 citations) identify allocation as key for 6G capacity. AI-driven methods are proposed but lack standardization.
Integration with 5G/6G Standards
NTN compatibility with terrestrial core networks demands new protocols (Kodheli et al., 2020). Centenaro et al. (2021; 379 citations) survey open challenges in satellite IoT standards. Latency mismatches persist across architectures.
