What Operator Policy Can Do
Operator policy enables the operator to specify a policy with rules governing the services, facilities and privileges
available to subscribers.
available to subscribers.
A Look at Operator Policy on an SGSN
The following is only a sampling of what working operator policies can control on an SGSN:
APN information included in call activation messages are sometimes damaged, misspelled, missing. In such
cases, the calls are rejected. The operator can ensure calls aren't rejected and configure a range of methods for
handling APNs, including converting incoming APNs to preferred APNs and this control can be used in a
focused fashion or defined to cover ranges of subscribers.

focused fashion or defined to cover ranges of subscribers.
In another example, it is not unusual for a blanket configuration to be implemented for all subscriber profiles
stored in the HLR. This results in a waste of resources, such as the allocation of the default highest QoS setting
for all subscribers. An operator policy provides the opportunity to address such issues by allowing fine-tuning
of certain aspects of profiles fetched from HLRs and, if desired, overwrite QoS settings received from HLR.

A Look at Operator Policy on an S-GW
The S-GW operator policy provides mechanisms to fine tune the behavior for subsets of subscribers. It also can be used
to control the behavior of visiting subscribers in roaming scenarios by enforcing roaming agreements and providing a
measure of local protection against foreign subscribers.

The S-GW uses operator policy in the SGW service configuration to control the accounting mode. The default
accounting mode is GTTP, but RADIUS/Diameter and none are options. The accounting mode value from the call
control profile overrides the value configured in SGW service. If the accounting context is not configured in the call
control profile, it is taken from SGW service. If the SGW service does not have the relevant configuration, the current
context or default GTPP group is assumed.
