Paging and Idle Mode Operation is responsible to maintain a track and alert for MS when it is in idle mode for battery
power saving reasons. Paging is executed to alert MS when there is an incoming message. The following figure
illustrates the paging operation along with paging and idle mode elements in the system.

ASN Paging Controller and Location Registry (PC/LR) supports connection management and mobility across cell sites
and inter-service provider network boundaries through processing of subscriber control and bearer data traffic.

ASN Paging Controller and Location Registry Reference Model
../../../GRAPHICS/Production/ASN_GW/Paging_network_reference_model_v1.wmf
In WiMAX networks, MS is tracked when it is in the idle mode and information is stored to a Location Register (LR).
Paging Controller (PG) in retrieves the location from LR and alerts the Paging agent (PA) in BS to signal to MS.

Location information for idle mode subscribers is maintained in a Location Register central database that is co-located
on an anchor paging controller. Idle mode can be initiated by the mobile device or the network.

The ASN PC/LR either run as a stand-alone function in a separate chassis or as an integrated service running on same
chassis as the Anchor Authenticator (A-PC)/Anchor Datapath (A-DP) ASN GW. The current implementation is based
on a topologically unaware paging scheme where the A-PC does not have global awareness of all member base stations
in a paging group. The A-PC uses a single step paging operation where paging notifications are sent to the last reported
serving paging controller or directly attached base station.

Network Controlled QoS
Benefits
This feature provides control of QoS for subscriber from network element side; i.e. GGSN. It uses bearer control mode
and Active Charging Services parameters to provide packet filtering and other quality class identifier related
configurations.
and Active Charging Services parameters to provide packet filtering and other quality class identifier related
configurations.
Description
Network-controlled QoS is the method by which the QoS for a PDP context (primary or secondary) is updated on the
request of the GGSN through Network Requested Update PDP Context (NRUPC) message. It can also activate a new
secondary PDP context on Network Requested Secondary PDP Context Activation (NRSPCA) message from the
GGSN.
