Abstract
The application provides a method for providing an internet protocol (IP) address to a terminal device by a network node. The network node receives, from the terminal device, a request for acquiring an IP address in a packet data network (PDN) connection. The request includes a requested IP address version. The network node allocates an IP address for the terminal device in response to the request, and sends the address allocated by the network node and a PDN address capability to the terminal device. The PDN address capability is determined by the network node according to the request, and the PDN address capability indicates that only an assigned version of the allocated IP address is allowed by the network node in the PDN connection.
