Step S5:eNodeB is mapped to Radio Bearer QoS (radio bearer QoS) with Bearer QoS (carrying QoS), sends Radio Bearer Setup Request (radio bearer is set up request) message then to UE.

UE uses UL TFT to decide the mapping of SDF (Service Data Flow, business data flow) to radio bearer.

The NAS of step S6:UE (Non-Access Stratum, Non-Access Stratum) layer is set up the response cell of session management, and UE confirms the activation of radio bearer to eNodeB transmission Radio Bearer Setup Response (radio bearer response) message then.

Step S7:eNodeB sends Bearer Setup Response (carry and set up response) message and gives MME activation to confirm to carry.

Can eNodeB indicate the QoS of the carrying of desired foundation be assigned with.

Step S8:MME sends Create Dedicated Bearer Response (dedicated bearer is set up response) message.

Give Serving GW activation to confirm to carry.

Step S9:Serving GW sends Create Dedicated Bearer Response message, gives PDN GW activation to confirm to carry.

Step S10: trigger if the activation of dedicated bearer is PCC DecisionProvision message through PCRF, whether PDN GW sends Provision Ack message and is reinforced for PCRF with the indication PCC decision (QoS policy) that PCRF was asked.
