Feature Operation Details

3 Feature Operation Details

Emergency Unlock Reset is a licensed feature that works in conjunction withthe Emergency Unlock feature which is part of the basic LTE functions.

To perform an Emergency Unlock Reset is to apply a License Key File (LKF)containing an Emergency Unlock Reset key. Emergency Unlock Reset can beapplied after the first or second activation of the Emergency Unlock featureand will return the Emergency Unlock feature to its initial state and clear theemergency unlock alarm.

The following figure shows the various states of the Emergency Unlock featureand how the use of Emergency Unlock Reset will change the state:

Figure 1 States of Emergency Unlock

The Licensing MO attribute EmergencyStatus will show the current stateof the Emergency Unlock feature. Possible states are:

NEVER_USED: Emergency status has not been activated since the lastlicense was installed

ACTIVE: The first time in emergency status. All license-controlled functionsget unlimited capacity. The maximum time in this state is 7 days

USE_DEGRADED: All features and capacities are license-controlled inaccordance with the installed LKF

549/1553-HSC 105 50/1-V2 Uen D | 2011-11-28


ACTIVE_AGAIN:. The second time in emergency status. All licensecontrolled functions get unlimited capacity and all features are enabled.The maximum time in this state is 7 days

USE_DISABLED: All features and capacities are license-controlled inaccordance with the installed LKF

If the emergency status is: NEVER_USED, USE_DEGRADED orUSE_DISABLED the node is licensed controlled. If emergency status isACTIVE or ACTIVE_AGAIN the RBS gets unlimited capacity and functions.

The only way to return the emergency status to the NEVER_USED state isto perform an Emergency Unlock Reset by applying the new license key filecontaining the EMERGENCY RESET KEY.

An alarm is raised upon entering the ACTIVE state. The alarm will remain untilthe Emergency Unlock Reset is applied and the state returns to NEVER_USED

3.1 Network Configuration RequirementsThe use of Emergency Unlock and Emergency Unlock Reset only makes senseif the RBS capacity and function is being constrained below its hard limit due tolicensing restrictions.

3.2 Emergency Unlock Reset Process StepsThis section describes the main process steps for the feature flow.

Order a new Emergency Unlock Reset license

Allocate/activate in ELIS the Emergency Unlock Reset license to theENodeB identity (ULN)

Create a new LKF adding the license and key for Emergency Unlock Reset

Network Impact

5 Network Impact

This section describes how the feature impacts the network functions andcapabilities.

If the RBS is currently in the emergency state, the Emergency Unlock Reset willrestore capacity and functions to the licensed level again. RBS capacity andfunctions will change according to the licensed features available.

NOTE: If any License Key has expired or in any way changed during theEmergency Unlock period, those keys will be expired after ending emergencyunlock, hence that feature or features have a changed behavior. It is not thecase that the RBS reverts back to the state it had when Emergency Unlock wasordered, it simply starts to enforce License Control again.
