Abstract
A method for assigning network addresses is provided. When a mobile node (MN) moves to an access domain (AN) of a visited network, the method, in the visited network, includes: receiving a network access request sent by the MN; determining a home network of the MN according to user information of the MN, and sending an authentication request to the home network for authenticating the MN; receiving an authentication response returned by the home network, where the authentication response includes a local home of address (L-HoA) for identifying the AN where the MN is currently located; and assigning a local care of address (L-CoA) to the MN, where the L-CoA identifies position information of the MN in the current AN. Correspondingly, a network and a network node are provided. Thus, technical solutions can implement address assignment when the MN moves.
