Each vendor and operator may have different implementation of tacking area management as per their requirement. Number of subscribers are not unique across the LTE network geography.
Following things may be considered for choosing suitable tracking area management scheme:
- An individual subscriber/group of subscriber (Closed subscriber group) mobility pattern.
- Subscriber density at a particular area.

Usually, network avoid TAU flood which may happen when a huge number of subscriber moving together from one cell to another cell.
For example: Travelling by bullet train is one of the examples.
