Tracking Area

Overview#

Tracking Area is the 3GPP LTE area which is a set of cells and can be grouped into lists of tracking areas (TA lists), which can be configured on the User Equipment (UE).

Tracking Area updates are performed periodically or when the User Equipment moves to a Tracking Area that is not included in its TA list.

Mobile Network Operators can allocate different Tracking Area lists to different User Equipment. This can avoid signaling peaks in some conditions: for instance, the User Equipments of passengers of a train may not perform Tracking Area updates simultaneously.
