ASN Paging Controller and Location Registry Overview

Paging Agent (PA)

The paging agent is a functional entity, implemented in an ASN base station, that handles the interaction between PC-
and paging-related functionality.
Paging Group (PG)
A paging group is a logical entity comprising one or more paging agents. A paging group resides entirely within a NAP
boundary. Paging groups are managed by the network management system and provisioned per the access network
operator's provisioning requirements.
