Patent ID: 7505778

Claim:
A wireless communication method for a Bluetooth device connected to a plurality of piconets and operating in a scatter mode, comprising steps of: (a) establishing credit values by link for the plurality of piconets, and a total sum of respective credit values of links as a temporary account value; (b) updating the credit values by link and the temporary account value every slot based on a predetermined algorithm; (c) performing communications through a link selected based on a comparison result of the respective credit values of links at each Presence Point (PP); and (d) unevenly redistributing predetermined credit values based on respective characteristics of the links and returning to the step (b) in one of the two cases that the communications are interrupted with a POLL_NULL sequence and that the temporary account value becomes the same as the total number, n, of links, wherein the step (d) redistributes a credit value C to the respective credit values of links based on the inverse of T scatter — poll temporary account value becomes the same as the total number, n, links, the T scatter — poll being a parameter negotiated between corresponding pioconets by a Link Manager Protocol (LMP) with a scatternet formed.
