The Rx interface supports the QoS resource reservation for reserving bandwidth in the IP access network. The Rx reference point is used to exchange application level session information between the Policy and Charging Rules Function (PCRF) and the P-CSCF. The SBC, acting as P-CSCF creates a TCP connection with the configured PCRFs
