Abstract
By introducing a concept such as an equivalent SNPN, mobility can be improved, service continuity can be improved, NSSAI can be appropriately managed, and an equivalent SNPN list can be appropriately managed. In a registration procedure, a UE transmits a registration request message to start a timer T3510, and in a case that the UE receives a registration reject message without integrity protection including a 5GMM cause value indicating an illegal UE, the UE stops the timer T3510 in operation and deletes an equivalent SNPN list stored in the UE.
