Abstract: The present invention provides an IP address assignment apparatus and method. A packet data gateway receives a connection establishment request that is sent by a mobility management network element and that carries user location information, assigns an IP address to the terminal according to a correspondence between the user location information and an IP address pool, and feeds back the IP address to the mobility management network element. In the present invention, effects that the packet data gateway can assign an IP address according to a location of a terminal, and different IP addresses are assigned at different regions are achieved.

Abstract: The application relates to a route delivery method and device. A location information of user equipment UE is received by a control plane network element device. A client IP address used by the control plane network element device to access a third-party server is determined based on the location information by the control plane network element device. An access request message is sent by the control plane network element device to the third-party server carrying the client IP address. A UE IP address assigned by the third-party server to the UE based on the client IP address is received by the control plane network element device. A user plane network element device configured to deliver a route to the UE is determined based on the UE IP address and the location information by the control plane network element device.
