Question: In a 5G network utilizing satellite access, what information does the Session Management Function (SMF) obtain to support data connectivity charging via satellite access?
Option 1: Cell ID and Satellite Backhaul Category
Option 2: User Equipment (UE) Location and Satellite Signal Strength
Option 3: Radio Access Technology (RAT) type for NR satellite access (e.g., NR(LEO), NR(MEO), NR(GEO), NR(OTHERSAT))
Option 4: International Mobile Subscriber Identity (IMSI) and Packet Data Network (PDN) Type
Explanation: To accurately charge for data connectivity via satellite access in a 5G network, the SMF needs to identify the specific type of satellite access being used. This is achieved by obtaining the RAT type for NR satellite access, which can be one of the following: Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geostationary Orbit (GEO), or Other Satellite (OTHERSAT). This information is crucial for differentiated charging based on the satellite access technology used.
