UMTS LTE Mobility States Slide
Mobility states are the status conditions of a mobile device as it relates to a communication network. Mobility states include detached (unknown), active (communicating), and idle (awaiting actions).

This figure that UMTS LTE device starts in the detached (unknown status) state when it is turned on. After it registers with the system, it changes into the active state. If the device is inactive for a period of time (does not transfer information), it may be moved into the idle mode. If there is data to be transferred, the mode may be changed back to the active state. When a device is powered off, it informs the system (deregisters) and detaches.
