<p>A method for Packet Gateway (PGW) selection. The method comprises: a 3GPP AAA server receiving a request-type indication transmitted by the PGW, wherein the request-type indication is used to indicate the type of a process executed by User Equipment (UE) or to indicate whether an IP address is preserved; and the 3GPP AAA server selecting a target PGW according to the request-type indication. A 3GPP AAA server, a Packet Gateway (PGW) and User Equipment (UE) are also provided in the embodiments of the present invention. With the embodiments of the present invention, the dynamic adjustment of the PGW is achieved, and an unnecessary PGW re-selection process is avoided.</p> |
