Study on application enablement for Satellite access enabled 5G Services
The present document is a technical report capturing the study on application enablement for Satellite access enabled 5G Services over 3GPP networks. The aspects of the study include identifying architecture requirements, supporting architecture for satellite access enabled 3GPP services and application enablers (either by defining new functional model or by enhancing existing functional model), and corresponding solutions.
The study is based on the requirements as defined in 3GPP TS 22.261 [2] and related use cases (for e.g. in 3GPP TR 22.822 [3] and 3GPP TR 22.865 [4]). The study is dependent on 3GPP TS 23.501 [5] (5GC architecture for satellite access for NR), 3GPP TS 23.502 [6] (procedures for NR satellite access), 3GPP TS 23.503 [7] (PCF for Satellite backhaul), 3GPP TS 23.401 [8] (EPC architecture for satellite access for IoT), 3GPP TS 23.682 [9] (EPC architecture enhancements to facilitate communications with packet data networks and applications).
