Abstract
A path switching system is provided, in which when UE has been offloaded from a first PDN-GW to a second PDN-GW, if there is an additional connection of the UE to the first PDN-GW, processing related to the additional connection can be performed on the UE side. The system includes: a control unit for sending a mobile terminal a message including information indicative of having switched relay devices, which relay a packet between the mobile terminal and a communication device, from a first relay device to a second relay device; and the mobile terminal for determining whether there is an added path other than part of a path from the mobile device before movement to the communication device and capable of being managed by the control unit, established between the mobile terminal and the first relay device, and when there is the added path, performing processing on the added path.
