Description Defines the tracking area update EMM procedure executed by the
|
|
Non-Access Stratum.
|
|
|
|
The tracking area updating procedure is always initiated by the
|
|
UE and is used to update the registration of the actual tracking
|
|
area of a UE in the network, to periodically notify the availa-
|
|
bility of the UE to the network, for MME load balancing, to up-
|
|
date certain UE specific parameters in the network.
