Abstract
Disclosed is a method for changing a role over control authorization performed in a communication apparatus. The method may comprise receiving, from a second controller, a role-request message requesting a role change of the second controller to a master controller; transmitting a role status request message for confirmation of the role change of the second controller to a first controller which is a previous master controller; and determining whether to accept the role change of the second controller according to a role status response message received from the first controller. Therefore, reliability may be guaranteed when a role of master controller is changed.
