A method for selecting a PDN gateway PGW is disclosed. The method includes: receiving, by a 3GPP AAA server, a request type indication sent by a PDN gateway PGW, where the request type indication is used for indicating a type of a procedure executed by a user equipment UE or is used for indicating whether an IP address is preserved; and selecting, by the 3GPP AAA server, a target PGW according to the request type indication. Embodiments of the present invention further provide a 3GPP AAA server, a PDN gateway PGW, and a user equipment. By adopting the embodiments of the present invention, a dynamic adjustment of a PGW can be implemented, and an unnecessary PGW reselection procedure is avoided. |
