Abstract
According to an aspect of the present invention, a mobile terminal apparatus and an intra-core network apparatus do not enable congestion control during connection of a mobile terminal apparatus to a non-public network (NPN) in 5GS. Alternatively, during connection of the mobile terminal apparatus to the NPN in 5GS, the mobile terminal apparatus and the intra-core network apparatus enable congestion control only in a public land mobile network (PLMN) specific to the congestion control to provide a congestion control method in an NAS level to the mobile terminal apparatus being connected to the non-public network (NPN) and the intra-core network apparatus in 5GS.
Claims2
A User Equipment (UE) comprising:
- a controller;
- and
- a transmission and reception unit, wherein
- the controller is configured to start a timer for a Data Network Name (DNN) based congestion control with a back-off timer value in a case that the transmission and reception unit receives a cause value to start the timer and the back-off timer value,
- the cause value indicates insufficient resources, and
- the timer is started on a per DNN and Stand-alone Non-Public Network (SNPN) basis in case of SNPN.
A communication control method performed by a User Equipment (UE),
- the communication control method comprising:
- starting a timer for a Data Network Name (DNN) based congestion control with a back-off timer value in a case that the UE receives a cause value to start the timer and the back-off timer value, wherein
- the cause value indicates insufficient resources, and
- the timer is started on a per DNN and Stand-alone Non-Public Network (SNPN) basis in case of SNPN.
