3. The configuration management server in the primary VAL system of the VAL user retrieves the VAL user profile from the VAL user database in that primary VAL system. The identification of the partner VAL system to which the VAL user is attempting to migrate is used to determine which VAL user profile is retrieved for that VAL user for migration to that partner VAL system.
4. The configuration management server in the primary VAL system provides the VAL user profile to the configuration management server in the partner VAL system of the VAL user, optionally requesting validation of the modified VAL user profile.
5. The partner VAL system of the VAL user modifies the VAL user profile according to local configuration information and stores the modified VAL user profile in the VAL user database in the partner VAL system.
6. If the primary VAL system requested validation of the VAL user profile in step 4, the configuration management server in the partner VAL system of the migrating VAL user may send the modified VAL user profile to the configuration management server of the primary VAL system of the VAL user to allow the primary VAL system of the VAL user to validate the modified VAL user profile.
7. The primary VAL system of the migrated VAL user validates the modified VAL service profile of the migrated VAL user.
8. The primary VAL system of the migrated VAL user responds to the partner VAL system with the results of the validation process.
9. The configuration management server in the partner VAL system provides the VAL user profile to the configuration management client of the migrating VAL user,
NOTE: Step 9 is not followed if the validation process fails.

|
23.434
|
12.3.3.2 Primary VAL system
|
Figure 12.3.3.2-1 is a high level user authentication and authorization flow.
NOTE: The specific user authentication and authorization architecture required by the VAL services in order to realize the VAL user authentication and authorization is specified in subclauses 5.2.3, 5.2.4 and 5.2.5 of 3GPP TS 33.434 [29].
The user authentication process shown in figure 12.3.3.2-1 may take place in some scenarios as a separate step independently from a SIP registration phase, for example if the SIP core is outside the domain of the VAL server.
A procedure for user authentication is illustrated in figure 12.3.3.2-1. Other alternatives may be possible, such as authenticating the user within the SIP registration phase.
Figure 12.3.3.2-1: VAL user authentication and registration with Primary VAL system, single domain
1. In this step the identity management client begins the user authorization procedure. The VAL user supplies the user credentials (e.g. biometrics, secureID, username/password) for verification with the identity management server. This step may occur before or after step 3. In a VAL system with multiple VAL services, a single user authentication as in step 1 can be used for multiple VAL service authorizations for the user.
2. The signalling user agent establishes a secure connection to the SIP core for the purpose of SIP level authentication and registration.
3. The signalling user agent completes the SIP level registration with the SIP core (and an optional third-party registration with the VAL service server(s)).
NOTE 1: The VAL client(s) perform the corresponding VAL service authorization for the user by utilizing the result of this procedure.
NOTE 2: Steps 2 and 3 are not required to be performed if the VAL service does not use SIP.
