Dimensioning Tracking Area for LTE Network
International Journal of Soft Computing and Engineering (IJSCE) ISSN: 2231-2307, Volume-4, Issue-1, March 2014
Mobility management (MM) is one of the main
functions in mobile networks. It aims to track the user equipment
(UEs) and to allow calls, other mobile phone services to be
delivered to UEs. For any mobility protocol there are two separate
problems to be solved. One is location management (or sometimes
called reachability), which keeps track of the positions of a UE in
the mobile network. The other one is handover management (or
sometimes called session continuity)…Mobility management (MM) is one of the main
functions in mobile networks. It aims to track the user equipment
(UEs) and to allow calls, other mobile phone services to be

problems to be solved. One is location management (or sometimes
called reachability), which keeps track of the positions of a UE in
the mobile network. The other one is handover management (or
sometimes called session continuity), which makes it possible for a
UE to continue its sessions while moving to another cell and
changing its access point. This document focuses on the location
management problems. Tracing UEs in a mobile network is the
key task in location management. Tracking Area (TA) in LTE is a
logical grouping of cells in a network. TA is almost the same
concept as the Location Area (LA). In configuring TAs, a key
consideration is to minimize the total amount of signaling
overhead.Other authorsSee publication -
