Configuring Operator Policy-Based S6d Interface Selection (Optional)
It is mandatory for the SGSN and GPRS services to have either a MAP service association or an HSS-Peer-Service
association.
association.
If no MAP service is associated with the SGSN or GPRS services, and only the HSS service is associated with
the SGSN or GPRS services, then the S6d interface is selected.
If both the MAP service and the HSS-Peer-Service are associated with the SGSN or GPRS service, by default
the Gr interface is selected. To override the default use of the Gr interface, configure the operator policy to
select the

s6d-interface
.
Once the interface selection is configured, the call-control-profile is first checked to determine whether to select
the MAP-interface or HSS-interface. If neither the MAP nor HSS is configured under the call control profile,
then the system checks the configured SGSN or GPRS-services.
then the system checks the configured SGSN or GPRS-services.
Step 1
Access Call Control Profile Configuration Mode and create a call-control-profile.
Step 2
Associate the configured HSS peer service with the S6d interface. The
s6d-interface
option must be selected.
Example Configuration
config
call-control-profile <name>
associate hss-peer-service <name> s6d-interface
end
Configuring the Subscription Interface Preference for the S6d Interface
(Optional)
The S4-SGSN provides a mechanism to associate a MAP service with call-control-profile. In some situations, it is
possible that both the MAP service and the HSS peer service are associated with the Call Control Profile. In these cases,
operators can configure the preferred subscription interface.
possible that both the MAP service and the HSS peer service are associated with the Call Control Profile. In these cases,
operators can configure the preferred subscription interface.
Step 1
Access Call Control Profile Configuration Mode and create a call-control-profile.
Step 2
Specify the preference of the subscription-interface. Selecting the
hlr
option will cause the MAP protocol to be used to
exchange messages with the HLR. The
hss
option causes the Diameter-protocol to be used to exchange messages with
the HSS.
Example Configuration
config
call-control-profile <name>
prefer subscription-interface { hlr | hss }
