Abstract
A system and method for transmitting packet data in a communications system assigns an IP address to a terminal based on a network access identifier corresponding to the terminal, and then sends packet data to the terminal using the IP address. The terminal may be a simple IP user terminal or a mobile IP user terminal, and the packet data being sent preferably corresponds to an IP push service. In order to send the packet data, a protocol link is established between the terminal and network. Transmission of packet data on this link may be managed using an information table which relates information corresponding to the IP address to the network access identifier. This table is updated with information relating to the IP address when, for example, the network access identifier changes, when a point-to-point protocol timer expires, when an IP registration expires a location of the terminal changes. Upon expiration of any of the aforementioned time periods, the link between the terminal and network may be eliminated, thereby freeing the IP address for use by other terminals in the system.
