Abstract

Paging load and/or registration load in a network is reduced by using different types of identifiers to specifying which nodes page an access terminal in the network. In some aspects, the network maintains a list that specifies that certain individual nodes (e.g., cells or sectors) are to page a given access terminal and/or that one or more zones (e.g., tracking areas) are to page the access terminal. In some aspects, an access terminal in a network may be configured to provide a forward-looking paging list to the network. The list provided by an access terminal may specify different types of node identifiers (e.g., individual node identifiers, subscriber groups, etc.). The network may then use the list to determine which nodes are to page a given access terminal such that when the access terminal moves to a different node, that node may already be configured to page the access terminal. In some aspect paging load and registration load are managed in a deployment that includes different types of access points. For example, access points of a first type (e.g., macro nodes) may provide service over relatively large coverage areas and access points of a second type (e.g., femto nodes) may provide service over smaller coverage areas and/or provide restricted service.
