The meaning of the different cause values is specified in the following table. In general, "not supported" cause values indicate that the related capability is missing. On the other hand, "not available" cause values indicate that the related capability is present, but insufficient resources were available to perform the requested action.

Radio Network Layer cause

Meaning

Cell not Available

The concerned cell is not available.

Handover Desirable for Radio Reasons

The reason for requesting handover is radio related.

Handover Target not Allowed

Handover to the indicated target cell is not allowed for the UE in question.

Invalid AMF Set ID

The target NG-RAN node doesn’t belong to the same AMF Set of the source NG-RAN node, i.e. NG handovers should be attempted instead.

No Radio Resources Available in Target Cell

The target cell doesn’t have sufficient radio resources available.

Partial Handover

Provides a reason for the handover cancellation. The target NG-RAN node did not admit all PDU Sessions included in the HANDOVER REQUEST and the source NG-RAN node estimated service continuity for the UE would be better by not proceeding with handover towards this particular target NG-RAN node.

Reduce Load in Serving Cell

Load in serving cell needs to be reduced. When applied to handover preparation, it indicates the handover is triggered due to load balancing.

Resource Optimisation Handover

The reason for requesting handover is to improve the load distribution with the neighbour cells.

Time Critical Handover

Handover is requested for time critical reason i.e. this cause value is reserved to represent all critical cases where the connection is likely to be dropped if handover is not performed.

TXnRELOCoverall Expiry

The reason for the action is expiry of timer TXnRELOCoverall.

TXnRELOCprep Expiry

Handover Preparation procedure is cancelled when timer TXnRELOCprep expires.

Unknown GUAMI ID

The target NG-RAN node belongs to the same AMF Set of the source NG-RAN node and recognizes the AMF Set ID. However, the GUAMI value is unknown to the target NG-RAN node.

Unknown Local NG-RAN node UE XnAP ID

The action failed because the receiving NG-RAN node does not recognise the local NG-RAN node UE XnAP ID.

Inconsistent Remote NG-RAN node UE XnAP ID

The action failed because the receiving NG-RAN node considers that the received remote NG-RAN node UE XnAP ID is inconsistent..

Encryption And/Or Integrity Protection Algorithms Not Supported

The target NG-RAN node is unable to support any of the encryption and/or integrity protection algorithms supported by the UE.

Multiple PDU Session ID Instances

The action failed because multiple instances of the same PDU Session had been provided to the NG-RAN node.

Unknown PDU Session ID

The action failed because the PDU Session ID is unknown in the NG-RAN node.

Unknown QoS Flow ID

The action failed because the QoS Flow ID is unknown in the NG-RAN node.

Multiple QoS Flow ID Instances

The action failed because multiple instances of the same QoS flow had been provided to the NG-RAN node.

Switch Off Ongoing

The reason for the action is an ongoing switch off i.e. the concerned cell will be switched off after offloading and not be available. It aides the receiving NG-RAN node in taking subsequent actions, e.g. selecting the target cell for subsequent handovers.

Not supported 5QI value

The action failed because the requested 5QI is not supported.

TXnDCoverall Expiry

The reason for the action is expiry of timer TXnDCoverall.

TXnDCprep Expiry

The reason for the action is expiry of timer TXnDCprep

In the current version of this specification applicable for Dual Connectivity only.

Improve User Bit Rate

The reason for requesting this action is to improve the user bit rate.

In the current version of this specification applicable for Dual Connectivity only.

User Inactivity

The action is requested due to user inactivity on all PDU Sessions. The action may be performed on several levels:

– on UE Context level, if NG is requested to be released in order to optimise the radio resources; or S-NG-RAN node didn’t see activity on the PDU session recently.

– on PDU Session Resource or DRB or QoS flow level, e.g. if Activity Notification indicate lack of activity

In the current version of this specification applicable for Dual Connectivity only.

The request is not accepted due to failed control plane integrity protection.

UP Integrity Protection Failure

The procedure is initiated because the SN (hosting node) detected an Integrity Protection failure in the UL PDU coming from the MN.

Slice(s) not supported by NG-RAN

The failure is due to slice(s) not supported by the NG-RAN node.

MN Mobility

The procedure is initiated due to relocation of the M-NG-RAN node UE context.
