Abstract
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.
