9.10  SEALDD policy configuration  p. 82

9.10.1  General  p. 82

The following clauses specify procedures, information flow for SEALDD policy configuration. In clause 9.10, the VAL server is a specific server for configurating SEALDD policy, and is different from the VAL server used for VAL application processing in other clauses.

9.10.2  Procedures  p. 82

9.10.2.1  SEALDD policy configuration  p. 82

Figure 9.10.2.1-1 illustrates the procedure for SEALDD policy configuration from the VAL server used for SEALDD policy configuration to the SEALDD server.

Up
Step 1.
The VAL server sends the SEALDD policy configuration request to the SEALDD server. The request includes the identifiers of the application traffic (e.g. VAL service ID, VAL server ID), VAL UE identify, and the SEALDD policy.
Step 2.
The SEALDD server performs authorization check to verify whether the VAL server can be accepted/authorized to configure the SEALDD policy.
Step 3.
Upon successful authorization, the SEALDD server stores the SEALDD policy for later use (e.g. for bandwidth control, transmission quality guarantee) and replies to the VAL server with the SEALDD policy configuration response.

9.10.2.2  SEALDD policy configuration update  p. 83

Figure 9.10.2.2-1 illustrates the procedure for SEALDD policy configuration update from the VAL server used for SEALDD policy configuration to the SEALDD server.

Up
Step 1.
The VAL server used for SEALDD policy configuration determines that the existing SEALDD policy needs to be updated, the VAL server sends the SEALDD policy configuration update request to the SEALDD server.
Step 2.
The SEALDD server performs authorization check to verify whether the VAL server can be accepted/authorized to update the SEALDD policy configuration.
Step 3.
Upon successful authorization, the SEALDD server updates the SEALDD policy configuration and replies to the VAL server with the SEALDD policy configuration update response.

9.10.2.3  SEALDD policy configuration delete  p. 84

Figure 9.10.2.3-1 illustrates the procedure for SEALDD policy configuration delete from the VAL server used for SEALDD policy configuration to the SEALDD server.

Up
Step 1.
The VAL server used for SEALDD policy configuration determines that the existing SEALDD policy needs to be deleted, the VAL server sends the SEALDD policy configuration delete request to the SEALDD server.
Step 2.
The SEALDD server performs authorization check to verify whether the VAL server can be accepted/authorized to delete the SEALDD policy configuration.
Step 3.
Upon successful authorization, the SEALDD server deletes the SEALDD policy configuration and replies to the VAL server with the SEALDD policy configuration update response.

NOTE 1:
This IE is used for the SEALDD enabled transmission quality guarantee, as specified in clause 9.9.
NOTE 2:
This IE is used for the SEALDD enabled bandwidth control, as specified in clause 9.8.
NOTE 3:
This IE is used for the SEALDD connection establishment and data delivery, as specified in clause 9.2.
