The invention relates to the wireless communication field, and discloses a method for establishing wireless network default carry and a system thereof, which ensure that the process for establishing the wireless network default carry is accelerated, and individual services are flexibly provided to a user. In the invention, one of various default PCC rules which are preconfigured is selected in a UE attachment process, and the default carry for the UE is established by PCEF according to the default PCC rules. A network side classifies the default carry in advance, and each default carry is corresponding to a default PCC rule. The network side can classify the default carry in advance according to modes such as charging standard, business model, service model, signed user level and so on. If the selected default PCC rule is preconfigured in the PCEF or is sent to the PCEF, a network entity selecting the default PCC rule only sends an identification number of the rule without sending the content of the rule to the PCEF.
