Wireless communication paging utilizing multiple types of node identifiers

摘要

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.

主权项

1. A method of wireless communication, comprising:
registering, by an access terminal, with a first access point; generating, by the access terminal, a suggested paging set indicating a set of nodes by which the access terminal wishes to be paged; receiving, by the access terminal, as a result of the registration, a list comprising identifiers of nodes that will page the access terminal, wherein the list is determined based at least in part on the suggested paging set, and the identifiers of nodes comprise at least one first type of identifier and at least one second type of identifier, wherein the second type of identifier relates to a tracking area; and receiving, by the access terminal, an indication relating to registration at a second access point, wherein the indication implies that an identifier of the first type is to be used for the registration at the second access point.
