Description Defines EMM procedures executed by the Non-Access Stratum

upon receiving notifications from lower layers so that data

transfer succeed or failed, or NAS signalling connection is
|
|
released, or ESM unit data has been received from under layer,
|
|
and to request ESM unit data transfer to under layer.
