METHOD, APPARATUS AND SYSTEM FOR MOVING WIRELESS TERMINALS IN MOBILITY MANAGEMENT SERVING NODE POOL

摘要

The invention discloses a method for moving a wireless terminal in a mobility management serving node pool comprising at least a source mobility management serving node and a target mobility management serving node, comprising: initiating, from the source mobility management serving node, a first subscriber context procedure to inform the target mobility management serving node of a move action for the wireless terminal; launching, from the target mobility management serving node, a second subscriber context procedure to obtain a subscriber context for the wireless terminal from the source mobility management serving node, in response to the informing; and establishing a connection between a radio access node for the wireless terminal and a session management gateway node via the target mobility management serving node. An apparatus and a system are also disclosed for the same. With the solution, control plane and user plane traffic for the wireless terminal may be moved with a minimum of payload loss.
