Method and apparatus for network initiated data services

Abstract

Techniques are provided for conserving network resources in a network that initiates data services by communicating push data to a dormant terminal. Selected network resources associated with the dormant terminal are released, and maintained information for reaching the dormant terminal is updated when the point of network attachment of the dormant terminal changes.
