Unspecified

Sent for radio network layer cause when none of the specified cause values applies.

TX2RELOCOverall Expiry

The timer guarding the handover that takes place over X2 has abnormally expired.

Successful Handover

Successful handover.

Release due to E-UTRAN generated reason

Release is initiated due to E-UTRAN generated reason.

Handover Cancelled

The reason for the action is cancellation of Handover.

Partial Handover

Provides a reason for the handover cancellation. The HANDOVER COMMAND message from MME contained E-RABs to Release List IE and the source eNB estimated service continuity for the UE would be better by not proceeding with handover towards this particular target eNB.

Handover Failure In Target EPC/eNB Or Target System

The handover failed due to a failure in target EPC/eNB or target system.

Handover Target not allowed

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

TS1_RELOCoverall Expiry

The reason for the action is expiry of timer TS1_RELOCoverall.

TS1_RELOCprep Expiry

Handover Preparation procedure is cancelled when timer TS1_RELOCprep expires.

Cell not available

The concerned cell is not available.

Unknown Target ID

Handover rejected because the target ID is not known to the EPC.

No radio resources available in target cell

Load on target cell is too high.

Unknown or already allocated MME UE S1AP ID

The action failed because the MME UE S1AP ID is either unknown, or (for a first message received at the eNB) is known and already allocated to an existing context.

Unknown or already allocated eNB UE S1AP ID

The action failed because the eNB UE S1AP ID is either unknown, or (for a first message received at the MME) is known and already allocated to an existing context.

Unknown or inconsistent pair of UE S1AP ID

The action failed because both UE S1AP IDs are unknown, or are known but do not define a single UE context.

Handover Desirable for Radio Reasons

The reason for requesting handover is radio related.

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.

Resource Optimisation Handover

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

Reduce Load in Serving Cell

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

User Inactivity

The action is requested due to user inactivity on all E-RABs, e.g., S1 is requested to be released in order to optimise the radio resources.

Radio Connection With UE Lost

The action is requested due to losing the radio connection to the UE.

Load Balancing TAU Required

The action is requested for all load balancing and offload cases in the MME.

CS Fallback triggered

The action is due to a CS fallback that has been triggered. When it is included in UE CONTEXT RELEASE REQUEST message, it indicates the PS service suspension is not required in the EPC.

UE Not Available for PS Service

The action is requested due to a CS fallback to GERAN that has been triggered.

When it is included in the UE CONTEXT RELEASE REQUEST message, it indicates that the PS service suspension is required in the EPC due to the target GERAN cell or the UE has no DTM capability.

Radio resources not available

No requested radio resources are available.

Invalid QoS combination

The action was failed because of invalid QoS combination.

Inter-RAT Redirection

The release is requested due to inter-RAT redirection or intra-LTE redirection. When it is included in UE CONTEXT RELEASE REQUEST message, the behaviour of the EPC is specified in TS 23.401 [11].

Failure in the Radio Interface Procedure

Radio interface procedure has failed.

Interaction with other procedure

The action is due to an ongoing interaction with another procedure.

Unknown E-RAB ID

The action failed because the E-RAB ID is unknown in the eNB.

Multiple E-RAB ID Instances

The action failed because multiple instance of the same E-RAB had been provided to the eNB.

Encryption and/or integrity protection algorithms not supported

The eNB is unable to support any of the encryption and/or integrity protection algorithms supported by the UE.

S1 Intra system Handover triggered

The action is due to a S1 intra system handover that has been triggered.

S1 Inter system Handover triggered

The action is due to a S1 inter system handover that has been triggered.

X2 Handover triggered

The action is due to an X2 handover that has been triggered.

Redirection towards 1xRTT

The release of the UE-associated logical S1 connection is requested due to redirection towards a 1xRTT system e.g., CS fallback to 1xRTT, or SRVCC to 1xRTT, when the PS service suspension is required in the EPC. During this procedure, the radio interface message might but need not include redirection information.

Not supported QCI Value

The E-RAB setup failed because the requested QCI is not supported.

Invalid CSG Id

The CSG ID provided to the target eNB was found invalid.

Release due to Pre-Emption

Release is initiated due to pre-emption.

N26 interface not available

The action failed due to a temporary failure of the N26 interface.

Insufficient UE Capabilities

The procedure can’t proceed due to insufficient UE capabilities.

Maximum bearer pre-emption rate exceeded

The procedure can’t proceed because the number of requests exceed the maximum bearer pre-emption rate.

UP integrity protection not possible

The E-RAB cannot be accepted according to the required user plane integrity protection policy.

Transport Resource Unavailable

The required transport resources are not available.

Unspecified

Sent when none of the specified cause values applies but still the cause is Transport Network Layer related.

Normal Release

The release is normal.

Authentication Failure

The action is due to authentication failure.

Detach

The action is due to detach.

Unspecified

Sent when none of the specified cause values applies but still the cause is NAS related.

CSG Subscription Expiry

The action is due to the UE becoming a non-member of the currently used CSG.

UE not in PLMN serving area

The release is due to the UE not being within the serving area of its current PLMN (for IoT NTN).

Transfer Syntax Error

The received message included a transfer syntax error.

Abstract Syntax Error (Reject)

The received message included an abstract syntax error and the concerning criticality indicated “reject”.

Abstract Syntax Error (Ignore And Notify)

The received message included an abstract syntax error and the concerning criticality indicated “ignore and notify”.

Message Not Compatible With Receiver State

The received message was not compatible with the receiver state.

Semantic Error

The received message included a semantic error.

Abstract Syntax Error (Falsely Constructed Message)

The received message contained IEs or IE groups in wrong order or with too many occurrences.

Unspecified

Sent when none of the specified cause values applies but still the cause is Protocol related.

Control Processing Overload

Control processing overload.

Not Enough User Plane Processing Resources Available

No enough resources are available related to user plane processing.

Hardware Failure

Action related to hardware failure.

O&M Intervention

The action is due to O&M intervention.

Unspecified Failure

Sent when none of the specified cause values applies and the cause is not related to any of the categories Radio Network Layer, Transport Network Layer, NAS or Protocol.
