Content: PCRF is the policy and charging control element. PCRF functions are desbed in more detail in TS 23.203[ Policy and charging control architecture ]  [6]. In non-roaming scenario, there is only a single PCRF in the HPLMN associated with one UE's IP-CAN session. The PCRF terminates the Rx interface and the Gx interface. In a roaming scenario with local breakout of traffic there may be two PCRFs associated with one UE's IP-CAN session: - H-PCRF that resides within the H-PLMN; - V-PCRF that resides within the V-PLMN.
