Abstract:
A method and system of relocating user equipment, such as a mobile device in a network from a first mobility anchor to a second mobility anchor, includes providing an identifier address to the user equipment when the latter is anchored to the first mobility anchor or gateway. When the user equipment is relocated to be anchored at the second mobility anchor or gateway, a per-host locator address is associated with the user equipment, the per-host locator address directing network packets to be routed to the second mobility anchor. A destination address of network packets addressed to the identifier address is translated to the per-host locator address, such that the network packets are routed to the second mobility anchor, and the destination address of network packets that are addressed to the per-host locator address are reverse translated to the identifier address, and the packets are forwarded to the user equipment.
