5.36 RIM Information Transfer
Taught in 27. Overload, energy, deployment and the rest (The 5G system architecture, in depth).
The purpose of RIM Information Transfer is to enable the transfer of RIM information between two RAN nodes via 5GC. The RIM Information Transfer is specified in TS 38.413 [34].
When the source AMF receives RIM information from source NG-RAN towards target NG-RAN, the source AMF forwards the RIM information to the target AMF, as described in TS 38.413 [34] and TS 29.518 [71]. The AMF does not interpret the transferred RIM information.
