A method and system for dynamic forward assignment of IP addresses in a wireless network wherein a serving base station requests IP addresses of it neighboring cells. The serving base station then provides the requested IP addresses to the mobile stations it serves based on whether the mobile station will be entering a particular neighboring cell. Immediately upon entering the neighboring cell the mobile station establishes over the air communications with the neighboring cell's base station using one of the requested addresses. In another embodiment of the present invention each mobile unit is responsible for attaining IP addresses from the base stations of neighboring cells. Accordingly, the base stations serve as relay points for the IP address requests from the mobile unit to an address server.
A method for assigning internet protocol addresses in a wireless network, said method comprising the steps of:
A wireless network comprising:
The network of claim 11 wherein the backbone network is an internet protocol network.
The network of claim 11 wherein said forward address table comprises a list of at least one internet protocol addresses associated with a neighboring base station.
A method for assigning internet protocol addresses in a wireless network, said method comprising the steps of:
The method of claim 15 further comprising the step of transmitting said assigned internet protocol addresses to said mobile station.
The method of claim 16 wherein said step of transmitting said assigned internet protocol addresses further comprises the substeps of transmitting said assigned internet protocol addresses to said relaying serving base station and said serving base station relaying said assigned addresses to said mobile station.
The method of claim 16 further comprising storing said assigned internet protocol addresses in a forward address table in said mobile station.
The method of claim 18 further comprising the step of initiating, at the mobile station, the processes necessary for completing handoff to the neighboring base station.
The method of claim 18 further comprising the step of using said assigned internet protocol address for communication between the mobile station and the neighboring base station.
