HandoverPreparationInformation
HandoverPreparationInformation is an inter-node RRC message of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
This message is used to transfer the NR RRC information used by the target gNB during handover preparation or UE context retrieval, e.g. in case of resume or re-establishment, including UE capability information. This message is also used for transferring the information between the CU and DU.

Fields of HandoverPreparationInformation-IEs (5)
| Field | Description |
|---|---|
| ue-CapabilityRAT-List UE-CapabilityRAT-ContainerList since v15.1.0 | The UE radio access related capabilities concerning RATs supported by the UE. A gNB that retrieves MRDC related capability containers ensures that the set of included MRDC containers is consistent w.r.t. the feature set related information. |
| sourceConfig AS-Config · OPTIONAL Cond HO since v15.1.0 | The radio resource configuration as used in the source cell. |
| rrm-Config RRM-Config · OPTIONAL since v15.1.0 | Local RAN context used mainly for RRM purposes. |
| as-Context AS-Context · OPTIONAL since v15.1.0 | Local RAN context required by the target gNB or DU. |
| nonCriticalExtension SEQUENCE {} · OPTIONAL since v15.1.0 |
