This clause is related to the case when UE-initiated resource request and release is supported, and it is utilized for the PMIP-based S5/S8 traffic flow aggregates. In the non-roaming case, vPCRF will not be involved.

This procedure applies to the Non-Roaming (Figure 4.2.1-1), Roaming (Figure 4.2.1-2) and Local Breakout (Figure 4.2.3-4) cases. For the Roaming and Local Breakout cases, the vPCRF forwards messages between the Serving-GW and the hPCRF. In the Local Breakout case, the vPCRF forwards messages between the PDN-GW and the hPCRF. The optional interaction steps between the gateways and the PCRF in the procedures in Figure 5.5-1 only occur if dynamic policy provisioning is deployed. Otherwise policy may be statically configured with the gateway. Steps between A.1 and B.1 are described in clauses 5.4.1, 5.4.2 and 5.4.3 of TS 23.401 for resource allocation/modification or clause 5.4.4.1 for resource deactivation. Based on the QoS policy rules, the Serving-GW decides whether to initiate a dedicated resource allocation activation or dedicated resource allocation modification (with or without QoS update).The Serving-GW uses this QoS policy to assign the EPS Bearer QoS, i.e. it assigns the values to the bearer level QoS parameters (excluding AMBR); see clause 4.7.3 of TS 23.401 and sends the appropriate message to the MME.
