Dynamic assignment and validation of IP addresses in wireless IP networks

A method for dynamic assignment and validation of IP addresses in a wireless network, comprising the following steps:

• broadcasting IP messages from a mobile terminal to a wireless interface;
• determining whether header information in one of assignment request messages and validation request messages in received IP messages is a local broadcast IP address;
• determining whether the IP messages were received on one of the wireless interface and a wired interface if the header information indicates a broadcast IP address;
• and
• if the header information indicates a broadcast IP address, then discarding the received IP messages, else broadcasting the received IP messages to the wired interface.

A method for dynamic assignment and validation of IP addresses in a wireless IP network, comprising the following steps:

• adding a selected mobile terminal address to an address mapping table for a broadcast IP address when one of an assignment request and a validation request from the mobile terminal is received at a base station;
• broadcasting at least one of assignment information and validation information from IP address servers to those mobile terminals included in the address mapping table;
• and
• removing a selected mobile terminal address from the address mapping table for the broadcast IP address once the selected mobile terminal has received a valid IP address from an IP address server.
