6.5 Removal of an access from a PDN connection p. 40

6.5.1 Removal of 3GPP access p. 40

6.5.1.1 UE-initiated removal of 3GPP access from the PDN connection p. 40

In the case of E-UTRAN, when the UE removes the 3GPP access for the multi-access PDN connection and the multiple-access PDN connection is not the last PDN connection for 3GPP access, procedures as described in TS 23.401, clause 5.10.3 are referred with the following modifications.

Step 5.

PDN GW shall indicate to the PCRF the removal of 3GPP access for the multi-access PDN connection via IP-CAN Session Modification procedure, if dynamic PCC is applied for the PDN connection.

In the case of E-UTRAN, when the UE removes the 3GPP access for the multi-access PDN connection and the multiple-access PDN connection is the last PDN connection for 3GPP access, procedures as described in TS 23.401, clause 5.3.8.2.1 are referred with the following modifications.

Step 8.

PDN GW shall indicate to the PCRF the removal of 3GPP access for the multi-access PDN connection via IP-CAN Session Modification procedure, if dynamic PCC is applied for the PDN connection.

In the case of GERAN/UTRAN, when the UE removes the 3GPP access for the multi-access PDN connection, procedures as described in TS 23.060, clause 9.2.4 are referred with the following modifications.

Step 5.

PDN GW shall indicate to the PCRF the removal of 3GPP access for the multi-access PDN connection via IP-CAN Session Modification procedure, if dynamic PCC is applied for the PDN connection.

6.5.1.2 Network-initiated removal of 3GPP access from the PDN connection p. 42

In the case of E-UTRAN, when the network removes the 3GPP access for the multi-access PDN connection, the following procedures are referred.

Copy of original 3GPP image for 3GPP TS 23.161, Fig. 6.5.1.2-1: Network initiated removal of 3GPP access via E-UTRAN from the PDN connection

(⇒ copy of original 3GPP image)

Step 1.

The PCRF shall indicate to the P-GW the removal of 3GPP access for the multi-access PDN connection via IP-CAN Session Modification procedure by updating or removing all PCC rules that are bound to this access.

Step 2-9.

The description of these steps is the same as for steps 2-9 in TS 23.401, clause 5.4.4.1. The P-GW deactivates the default bearer of this access.

Step 10.

The P-GW shall indicate to the PCRF the 3GPP access is removed from the multi-access PDN connection.

Step 11.

The description of these steps is the same as for steps 11 in TS 23.401, clause 5.4.4.1.

The optional interaction steps between the PDN GW and the PCRF in the procedures only occur if dynamic PCC is applied for the PDN connection.

In the case of GERAN/UTRAN, when the network removes the 3GPP access for the multi-access PDN connection, the following procedures are referred.

Step 1.

Step 2-3.

The description of these steps is the same as for steps A-B in TS 23.060, clause 9.2.4.3A.

Step 4-5.

The description of these steps is the same as for steps 2 in TS 23.060, clause 9.2.4.3.

Step 6-7.

The description of these steps is the same as for steps A-B in TS 23.060, clause 9.2.4.3B.

Step 8.

The description of these steps is the same as for steps 4-5 in TS 23.060, clause 9.2.4.3.

Step 9.

The P-GW shall indicate to the PCRF the 3GPP access is removed from the multi-access PDN connection.

The optional interaction steps between the PDN GW and the PCRF in the procedures only occur if dynamic PCC is applied for the PDN connection.
