A method for performing policy and charging control in different roaming scenarios includes: establishing multiple Packet Data Network (PDN) connections to the same Access Point Name (APN), and performing relocation of a Bearer Binding and Event Report Function (BBERF) after establishing multiple PDN connections to the same APN. This method implements the policy and charging control on multiple PDN connections established to one APN in the roaming scenarios of the home routed and local breakout.
