Abstract

The present invention provides a network switching method, a network controller, a related server, and a PGW (public data network gateway). The method includes that a first network controller transmits a PGW information acquisition request of the UE to a first home subscriber server (HSS) when the UE gets access, wherein the PGW information acquisition request includes a unified user identifier and / or a first user identifier of the UE and is configured to request the PGW selection information of the UE; the first network controller receives the PGW selection information of the UE transmitted from the first HSS; the first network controller selects a target PGW according to the PGW selection information, and transmits a communication link establishment request to the target PGW and transmits a PDN connection communication link establishment request to the UE for requesting the establishment of a communication link between the target PGW and the UE. In this way, the UE does not need to change an IP address when moving in the networks of different participating service providers, thereby enabling service continuity of the UE between the networks of different participating service providers.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a network switching method, a network controller, a related server and a PGW (Public Data Network GateWay, packet data network gateway). Background technique [0002] The home server can manage user information through a unified user ID. Different networks under the same home server have a common anchor point PGW. When UE (User Equipment, user terminal) moves between different networks, it can connect to the external network through the same anchor point. Without changing the IP address. [0003] The existing technology supports UE switching between different networks under the same home server, but different PSPs (Participating Service Providers, service providers) use different home servers to manage user information, and the identity of the same UE in the home servers of different PSPs Differently, the networks of different home servers do not have a common PGW,...
