Classification Description

(1)~(7) This is the procedure to relocate the Authenticator from the S-ACR to the T-ACR,

the T-ACR triggers in order that the MS performs the EAP authentication

procedure with the AAA server again. The T-ACR completes the Authenticator

Relocation procedure by notifying the S-RAS of the authentication result.

(8)~(9) S_ACR sends MS context information to T_ACR.

(10)~(19) FA relocation and authenticator are triggered, and the registration of the PMIP or the

CMIP is processed.

(20)~(21) The S-ACR cancels the S-ACR registration of the MS in the HA.

(22)~(25) The S-ACR, in interoperation with the AAA server, updates the final accounting

information for the MS. If the Diameter is used as the AAA protocol, the S-ACR

performs the session release procedure from the AAA server. However, when the

RADIUS protocol is used, only the Accounting Request stop procedure and the

Accounting Response stop procedure are processed and the STR/STA

procedure is omitted.
