Inter-ASN Handover: ASN-Anchored Mobility
Inter-ASN handover is divided into the ASN-anchored mobility method via the R4
interface and the CSN-anchored mobility method via the R3/R4 interface. The following
figure indicates the inter-ASN handover procedure of the ASN-anchored mobility method,
the Serving ACR(S-ACR) performs the anchor function.

The HO signaling procedure is the same with the inter-RAS handover procedure, however
in the HO signaling procedure, the procedure of exchanging the HO signaling message via
the R4 interface is added between the S-ACR and the Target ACR(T-ACR).
