Usage Guidelines
For an initial network-requested PDP context creation, the system contacts the HLR (via the GSN-MAP
interworking node) to learn which SGSN is currently servicing the subscriber. The system keeps that information
in cache memory for the configured time, so that future network-requested PDP context creations for that
subscriber can be initiated without having to contact the HLR again.
