The embodiments of the present invention disclose a method, network element and terminal of achieving identity and location separation and interface identifier allocation. The method of achieving an identity and location separation network includes: an EPS network side network element acquiring an Access Identifier (AID) of a User Equipment (UE), and transmitting the acquired AID to the UE; a Packet Data Network Gateway (P-GW) to which the UE is attached allocating a subnet prefix for the UE, and transmitting the subnet prefix to the UE; and the UE combining into an IPv6 address using the AID as an interface identifier part of the IPv6 address and the subnet prefix as a subnet prefix part of the IPv6 address, and using the IPv6 address to configure the IPv6 address of the UE itself.

Method, network element and UE achieving identifier and location separation and interface identifier allocation

A method for a mobile node dynamically obtaining a location identifier, and a locator/ID separation protocol (LISP) network are provided. The method is applied in the LISP network, including: when a mobile node moves to a new location, sending an address information allocation request including a first option to an address information allocation device, wherein, the first option includes attribute information of which a value represents globally routable; after receiving the address information allocation request, the address information allocation device preferentially selecting globally routable address information in locally available address information resources, and then replying with an address information allocation response carrying the selected address information to the mobile node, wherein the address information includes an address or a routing prefix.

Method for mobile node to dynamically acquire location identifier, and LISP network

Provided are a system and method for realizing an identifier and locator separation network based on Internet Protocol version 6 (IPv6). The method includes that: a network prefix assigned for a terminal is taken as a part of an IPv6 address of the terminal, and a subscriber Access Identifier (AID) assigned for the terminal is also taken as a part of the IPv6 address. With the above technical solution, the additional overhead, brought by creating tunnels and removing tunnels, of the identifier and locator separation network realized based on the network can be solved.
