Local QoS Capping
The operator can configure a cap or limit for the QoS bit rate.
The SGSN can now be configured to cap the QoS bit rate parameter when the subscribed
QoS provided by the HLR is lower than the locally configured value.
QoS provided by the HLR is lower than the locally configured value.
Depending upon the keywords included in the command, the SGSN can: take the QoS
parameter configuration from the HLR configuration. take the QoS parameter configuration
from the local settings for use in the APN policy. during session establishment, apply the
lower of either the HLR subscription or the locally configured values.

Multiple PLMN Support
With this feature, the 3G SGSN now supports more than one PLMN ID per SGSN. Multiple
PLMN support facilitates MS handover from one PLMN to another PLMN.
PLMN support facilitates MS handover from one PLMN to another PLMN.
Multiple PLMN support also means an operator can 'hire out' their infrastructure to other
operators who may wish to use their own PLMN IDs. As well, multiple PLMN support
enables an operator to assign more than one PLMN ID to a cell-site or an operator can
assign each cell-site a single PLMN ID in a multi-cell network (typically, there are no more
than 3 or 4 PLMN IDs in a single network).

This feature is enabled by configuring, within a single context, multiple instances of either
an IuPS service for a single 3G SGSN service. Each IuPS service is configured with a
unique PLMN ID. Each of the SGSN services must use the same MAP, SGTPU and GS
services so these only need to be defined one-time per context.

Overcharging Protection
Overcharging Protection enables the SGSN to avoid overcharging the subscriber if/when a
loss of radio coverage (LORC) occurs.
loss of radio coverage (LORC) occurs.
When a mobile is streaming or downloading files from external sources (via background or
interactive traffic class) and the mobile goes out of radio coverage, the GGSN is unaware of
such loss of connectivity and continues to forward the downlink packets to the SGSN.

such loss of connectivity and continues to forward the downlink packets to the SGSN.
To accommodate such situations, the SGSN can be configured to set a proprietary private IE
extension to set the QoS to 0kbps upon a loss of radio coverage occurs. This setting notifies
the GGSN of the LORC to prevent overcharging.
