Abstract

The invention relates to address checking method and device and a network system, wherein the address checking method comprises the following steps of: acquiring a first IP address used in a first network by user equipment (UE); and checking the second IP address of the user equipment according to the first IP address, wherein the second IP address is an IP address used by the user equipment in the process of switching the first network into a second network. In the pre-registration process, the address checking method and device can check the second IP address used in the process of switching to the second network by the UE according to the first IP address after acquiring the first IP address used in the first network by the pre-registered UE to ensure the legality of the IP addresses of used network resources and improve the safety of the networks.
