Title:
METHOD FOR ESTABLISHING PLURALITY OF PDN CONNECTIONS BY MEANS OF CSIPTO
Document Type and Number:
WIPO Patent Application WO/2015/170862
Kind Code:
A1
Abstract:
Provided according to a disclosure of the present invention is a method for establishing a plurality of packet data network (PDN) connections in a user apparatus by means of coordinated selected IP traffic offload (CSIPTO). The method may comprise the steps of: receiving, from a network entity responsible for a control plane, an indication for a gateway rearrangement arising from CSIPTO; determining whether to maintain a previously established first PDN connection on the basis of the indication; establishing a new second PDN connection on the basis of the indication; if the previously established first PDN connection is to be maintained, marking one or more from among the first PDN connection and the second PDN connection.
