In the preceding example, the name of the configured DNN is "ims", location-dnn-profile is “loc1”, location-area-group is "lag1" and "lag2", and the dnn-profile is "dnnprof-imslag1" and "dnnprof-imslag2".

SMF selects location-dnn-profile “loc1” for the “ims” DNN received in PDU session request. The loc1 profile maps location-area-group to the dnn-profile. The SMF uses TAI and ECGI information from PDU session request to find the configured location-area-group "lag1". Then, the corresponding dnn-profile "dnnprof-imslag1" is selected.

After the "dnnprof-imslag1" dnn profile is selected, the SMF selects a suitable UPF based on the selection criteria that are specified in the UPF selection policy.
