Selecting a Paging Profile
AMF supports multiple paging profiles. Paging usually happens in stages, with each stage having its own algorithm configured.
AMF selects the operator policy based on SUPI-prefix. If the SUPI-prefix match isn’t found, it selects the operator-policy associated with the AMF-service.
The paging-map can be associated with the operator-policy. Each paging-map has a list of trigger-to-paging profile mapping to support unique precedence for each trigger. The available trigger types are:
-
5QI
-
PPI
-
DEREG
-
DNN
-
ARP
Paging profile selection is based on the configured precedence with matching trigger and value pair. When multiple trigger-value pair matches, AMF selects based on the higher precedence. Lower the value, higher the precedence.
Each paging profile has a list of stages with each stage defining a paging-algorithm to use.
