local RAIs. This variable allows for an integer from 1 to 10.
Usage
Important:
This feature is supported only for 3G subscribers until Release 15.0.
The command enables the SGSN to perform DNS query with an NRI when RAU comes from an SGSN
outside the pool. The SGSN uses NRI-FQDN-based DNS resolution for the non-local RAIs for 3G
subscribers in place of RAI-FQDN-based DNS resolution.
This functionality is applicable in situations for either inter- or intra-PLMN when the SGSN has not chosen a
local NRI value (configured with SGSN Service commands) other than
outside the pool. The SGSN uses NRI-FQDN-based DNS resolution for the non-local RAIs for 3G
subscribers in place of RAI-FQDN-based DNS resolution.
This functionality is applicable in situations for either inter- or intra-PLMN when the SGSN has not chosen a
local NRI value (configured with SGSN Service commands) other than
local-pool-rai
or
nb-rai
. This
means the RAI (outside pool but intra-PLMN) NRI length configured here will be applicable even for intra-
PLMN with differently configured NRI lengths (different from the local pool).
This functionality is not applicable to call control profiles with an associated MSIN range as ccprofile
selection is not IMSI-based. When this feature is enabled, the selection of the ccprofile is based on the old-
RAI and the PLMN Id (if configured) of the RNC where the subscriber originally attached.
