Abstract
Provided method includes receiving, from the source AN, a handover request requesting a handover of an AN of the user equipment, wherein the user equipment is configured with a per node level tunnel for connection to a target user plane function node, and wherein the per node level tunnel is a common connection tunnel which is generated in the node unit for all traffics between the target AN and the target user plane function node, determining whether a service provision through the per node level tunnel is possible, determining whether generation of a new per node level tunnel for the user equipment is necessary when it is determined that service provision is impossible, and generating the new per node level tunnel for the user equipment based on a result of the determination or changing the tunnel model of the user equipment to a different tunnel model.
