A method for storing an address of a network anchor point to a network server is provided The provided method includes the following steps: a terminal initiates an attach request or a bearer establishment request, and a network selects a network anchor point; and when the network anchor point assigns a first bearer context to the terminal, or a first connection is established between the network anchor point and the terminal, the network registers an address of the network anchor point to a network server. A method for deleting an address of a network anchor point from a network server is also provided, which includes the following steps: when a terminal or an entity in a network initiates a delete bearer request, the network instructs a network server to delete an address of a network anchor point that has been registered to the network server if the network anchor point no longer serves the terminal; and the network server deregisters the address of the network anchor point.
