Description Defines the EMM status procedure executed by the Non-Access
|
|
Stratum.
|
|
|
|
The purpose of the sending of the EMM STATUS message is to
|
|
report at any time certain error conditions detected upon
|
|
receipt of EMM protocol data. The EMM STATUS message can be
|
|
sent by both the MME and the UE.
