ROLE SWITCHING METHOD OF A DUAL ROLE DEVICE AND THE DUAL ROLE DEVICE, CAPABLE OF REDUCING CONSUMPTION POWER

摘要

PURPOSE: A role switching method of a dual role device and the dual role device are provided to reduce overhead which simultaneously keeps a default link and a reverse link.;CONSTITUTION: A host DRD(Dual Role Device) transmits MMC(Micro-scheduled Management Command)s to a device DRD(S10). A role change request command is transmitted to the host DRD through a DNTS(Device Notification Time Slot)(S12). The host DRD accepts role switching in response to the request command(S14). The host DRD consecutively transmits MMCs of M to the device DRD(S16). The device DRD switches its role into the role of the host DRD(S17).;COPYRIGHT KIPO 2010
