Abstract:
A User Equipment (UE) includes a transmitter configured to, in a case that, at a time when a Public Land Mobile Network (PLMN) is changed, a first timer is running for a certain Data Network Name (DNN) and an old PLMN but that a second timer is not running for the DNN or a new PLMN and is not deactivated, be capable of transmitting a PDU session establishment request message for the DNN or no DNN in the new PLMN without stopping the first timer for the DNN and the old PLMN. Thus, a communication control method is provided that is used in a case that, in 5G congestion control in which multiple types of congestion control are applied, the PLMN is changed during application of the congestion control.
