Assumptions and requirements:
  1. Emergency calls shall be possible in all states, except in state 1.
  2. Power-off should cause transition to state 1 from all other states.
  3. The actions to be taken in state 5 is not defined.
  4. Realization of the dotted states (3, 4 and 6) depends upon the network requirements and the type of UE.
Description of the states of the UE access procedure
  1. UE-OFF:
    The UE is in OFF-condition. This means that the equipment is not active as an UE in a PLMN.
  2. WAIT:
    Waiting for the completion of the UE access conditions, which are related to the type of UE and to the PLMN, where in the UE is roaming (e.g. location updating).
  3. ENTER CARD:
    Request for entering of the subscriber card, (e.g. when no built in SIM module is available).
  4. ENTER PIN:
    Request for entering of the correct PIN.
  5. FAILURE TREATMENT:
    Waiting for removal the actual failure condition.
  6. ENTER PLMN:
    Request for selection of PLMN.
  7. SERV-AV:
    The UE is in a ready state. PLMN services are available to the user.
  8. In Case of Emergency (ICE)
    When a star key is pressed three times (***), the UE is unlocked and ICE information is available unless the subscriber has decided to prevent the display of the ICE information. If the UE has been locked in the previous state, then only the ICE information is available.
Description of the transitions between UE access states
ON:
The equipment becomes active as an UE in a PLMN.
REQ:
A request for user activity.
IOC:
Insertion of a subscriber card with SIM/USIM-module.
COMPLETE:
The PIN has been entered.
ENTERED:
A PLMN choice has been done.
FAILURE:
A failure condition has occurred in any other state during the UE access procedures.
CONDITIONAL:
One of the conditions the UE is waiting for in WAIT state has been lost. The UE goes back to the WAIT state.
"DONE":
The UE access failure condition has been corrected.
OK:
All the conditions the UE is waiting for in the WAIT state are accomplished.
ICE unlock
When a star key is pressed three times (***), the UE enters the In Case of Emergency (ICE) state unless the subscriber has decided to prevent the display of the ICE information.
"End" key
The UE goes back to the WAIT state.
