Title:
WIRELESS TERMINAL AND WWAN-SUPPORTING BASE STATION
Document Type and Number:
WIPO Patent Application WO/2017/018537
Kind Code:
A1
Abstract:
A wireless terminal according to one embodiment of the present invention is provided with a control unit that includes a first entity for carrying out WWAN communication with a WWAN-supporting base station, and a second entity that is positioned on a higher-order layer than the first entity. With regard to data on the wireless terminal, when the wireless terminal receives, from the WWAN-supporting base station, a switch instruction for switching the communication target network between a WWAN and a WLAN, the first entity notifies the second entity of an indicator indicating the switch of the communication target network.
