The receiver consumes quite a lot of power. Relatively speaking the purpose of the slot cycle is to permit the phone to keep the receiver turned off most of the time. This is vital to extend battery life.
When the mobile first registers with a base station, the base station and mobile determine which paging channel the mobile will use (if there is more than one) and what phase of the slot cycle that mobile will use. Thereafter, the phone wakes periodically, turns its receiver on briefly to see if it has an incoming call or if there is other traffic from the cell it must respond to, and if there is nothing then it shuts the receiver down again and waits until the next slot time.
When an incoming call arrives at a base station for a given mobile, the phone system of the caller generates the sound of a phone ringing as a comfort tone back to the caller (this tone comes in Alert With Information Message), and the base station waits until the slot time for the called mobile. When it comes around, the cell sends a message to the phone telling it that there is an incoming call. This causes the phone to waken and set up the call, and to begin to ring. If the phone doesn't respond to the page, the cell may try again on the next slot. Note:
The advantage of a longer slot cycle is that the phone spends a lower percentage of the time with its receiver on and thus the battery will last longer. It also means there is more capacity on the paging channel. The advantage of a shorter slot cycle is that the phone gets more chances to receive the page, and will receive the page sooner.
The mobile also has to perform Registration, to keep informing the base station what is its current location. More details on this in the Registration section.

Let us go about seeing how the mobile station is busy. See what the mobile does when is busy in a real environment? The most important thing the mobile does is to wake periodically and turn on its receiver briefly to see if it has been paged, which means to find out if there is an incoming call (mobile termination call) or a message. This happens on what is known as a slot cycle, and the base station controls the period of the slot cycle. Recall this is Slotted mode of operation Slot cycle indices are numbers from 0 to 7, and for any index the period is 1.28 seconds multiplied by 2Aindex.

All of registration messages sent by the phone are nearly identical, and they simply identify the phone and contain a few other important pieces of information about it. Despite how it sounds, they (deliberately) don't happen very often and (deliberately) represent a negligible impact on standby time. But they are necessary for the phone system as a whole to work properly.

Of course, the phone is also updating its display to show the current date and time and signal strength and amount of energy remaining in the battery, and perhaps other things depending on the phone model.

So in this regard a phrase is generally said which is :

That "idle" phone is plenty busy!
