Abstract:
1. A threshold-less method for mobile node handset handoff between channels of multiple base stations having a medium access control protocol used for forwarding Internet Protocol packets between multiple base stations and mobile nodes in voice over the Internet protocol systems on a wireless network comprising: multiple base stations in electrical communication with the Internet; said multiple base stations having channels; one or more mobile nodes in wireless electrical communication with one of said multiple base stations over said channels; said multiple base stations and said one or more mobile nodes each having a medium access control protocol; each of said multiple base stations transmitting a beacon signal; said beacon signal containing information regarding current Signal to Interference-plus-Noise Ratio, uplink interference, and channel capacity for each of said channels; said one or more mobile nodes scanning said beacon signal and storing said information regarding current Signal to Interference-plus-Noise Ratio for each of said channels; said one or more mobile nodes averaging said Signal to Interference-plus-Noise Ratio from multiple scans to determine an average Signal to Interference-plus-Noise Ratio; each of said one or more mobile nodes storing said average Signal to Interference-plus-Noise Ratio for a channel it is communicating over and determining a preferred channel list that contains a list of channels that have the best average Signal to Interference-plus-Noise Ratio; and, wherein when one of said one or more mobile nodes determines that the average Signal to Interference-plus-Noise Ratio of a new channel is better by a set amount than the average Signal to Interference-plus-Noise Ratio of said channel said mobile node is communicating with said mobile node hands off to said new channel if said uplink interference and channel capacity of said new channel allow handoff.
