A PT (e.g., Push-To-Talk, Push-To-View or Push-To-Data) service, and more particularly, to a method and device for controlling a floor (talk burst authority, permission to send media burst, etc.) in a PT service, are discussed. According to an embodiment, the method for controlling a state of a Push-To (PT) server, includes starting, by a PT server, a stop talking (T2) timer which is a type of media burst control timer that operates with respect to a terminal having permission to send a media burst; checking, by the PT server on expiry of the T2 timer, whether a media burst release message was already received while the T2 timer was running; and entering, by the PT server, a media burst idle state if the media burst release message was already received as a result of the checking step.
