Paging and power management schemes for local network access

Abstract

Paging and power consumption are managed in conjunction with providing local breakout in a wireless wide area network. In some aspects, if a packet destined for an access terminal is received at an access point that provides local breakout, the access point may inform the network so that the network will cause the access point to page the access terminal. Alternatively, in some aspects an access point that provides local breakout may maintain idle context of the access terminal, whereby the access point may autonomously page the access terminal (i.e., without involving the core network). In some aspects local breakout traffic is filtered at an access point to reduce the number of pages or packets sent to an access terminal. In some aspects an indication of a packet type is provided with a page message to enable an access terminal to determine whether to receive the packet. In some aspects a local link interface may be selectively disabled or enabled to limit traffic at an access terminal.

Benefits of technology

[0012]The disclosure relates in some aspects to enabling an access terminal to be paged if a local breakout packet destined for the access terminal is received at an access point. In some implementations, upon receipt of such a packet, the access point informs a network paging management entity (e.g., of the core operator network) so that this entity will cause the access point to page the access terminal. Alternatively, in some implementations the access point may maintain idle context of the access terminal, whereby the access point may autonomously page the access terminal (i.e., without involving a network paging management entity). In this way, the network may be relieved of paging-related operations for local breakout.

Problems solved by technology

As the demand for high-rate and multimedia data services rapidly grows, there lies a challenge to implement efficient and robust communication systems with enhanced performance.
