5.4.6.3 Core Network assisted RAN paging information
Taught in 9. Registration, reachability and paging (The 5G system architecture, in depth), 10. Radio, Wi-Fi, cable — every way in (The 5G system architecture, in depth).
Core Network assisted RAN paging information aids the RAN to formulate a RAN paging policy and strategy in RRC_INACTIVE state, besides the PPI and QoS information associated to the QoS Flows as indicated in clause 5.4.3.
CN assisted RAN paging information may be derived by the AMF per UE and/or per PDU Session based on collection of UE behaviour statistics, Expected UE Behaviour and/or other available information about the UE (such as subscribed DNN, SUPI ranges, Multimedia priority services) and/or information received from other network functions when downlink signalling is triggered.
The Core Network may provide the CN assisted RAN paging information to RAN in different occasions, e.g. during downlink N1 and N2 message delivery, etc.
