Author Frederic Maurel

|
|
Description Implements the EPS Mobility Management procedures executed
|
|
when the EMM-SAP is in EMM-REGISTERED.UPDATE-NEEDED state.
|
|
|
|
In EMM-REGISTERED.UPDATE-NEEDED state, the UE has to perform
|
|
a tracking area updating or combined tracking area updating
|
|
procedure, but access to the current cell is barred. The access
|
|
class may be blocked due to access class control, or the
|
|
network rejected the NAS signalling connection establishment.
|
|
No EMM procedure except tracking area updating or combined
|
|
tracking area updating or service request as a response to
|
|
paging shall be initiated by the UE in this substate.
