Title:
UE AND COMMUNICATION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2019/245004
Kind Code:
A1
Abstract:
User equipment (UE) that comprises a transmission unit that, when a public land mobile network (PLMN) is changed, when a first timer has been deactivated for one data network name (DNN) and an old PLMN but a second timer is not operating for the one DNN and a new PLMN and has not been deactivated, can transmit a PDU session establishment request message over the new PLMN for the one DNN or for no DNN without stopping the first timer. The present invention thereby provides a communication control method that, with respect to 5G congestion management in which a plurality of types of congestion management are applied, is for situations in which a PLMN has been changed during application of congestion management.
