Network-initiated method and system for establishing data communication using IP with a wireless terminal

摘要

A method and apparatus are provided for establishing data communication between a wireless network and a wireless terminal by means of a packet data protocol connection, using internet protocol. When a determination is made that the wireless terminal is active but does not have an internet protocol address, a page is initiated from the wireless network to the wireless terminal over a control channel requesting that the wireless terminal obtain a temporary internet protocol address. A temporary internet protocol address is then assigned to the terminal in response to a request from the terminal initiated in response to the page so that data communication can be established with the terminal based on the temporary address.
