Abstract: A method for network handover includes sending a first message that includes first information to a second network, where the first information is used to indicate that a user equipment needs to be handed over from a first network to the second network, so that a target gateway device allocates, to the user equipment according to at least the first information sent by the second network, a second Internet Protocol (IP) address that is the same as a first IP address and used when a second packet data network (PDN) connection is established by using the second network and the target gateway device, where the first IP address is an IP address used when the user equipment establishes a first PDN connection by using the first network and the target gateway device. Therefore, service continuity is ensured after a network handover.

Abstract: Embodiments of the present invention provide a method and a device for establishing a packet data network PDN connection. A method includes: receiving, by a trusted wireless local area network access network TWAN device, a trigger message from a user equipment; obtaining, by the TWAN device, an access point name APN from the user equipment; sending, by the TWAN device, a create session request message carrying the APN to a PDN gateway; receiving, by the TWAN device, a create session response message carrying an IP address from the PDN gateway; and sending, by the TWAN device, the IP address to the user equipment. In this way, an additional PDN connection or a non-default PDN connection is established for a user equipment to extend a network access range of the user equipment.
