Abstract: A method includes transmitting, by a user equipment (UE), a first message to a network node, the first message including a request for access to a first network according to a non-access stratum (NAS) protocol. The UE receives a second message from the network node, the second message including an indication of no network slice being available to service access to the first network requested by the UE. The UE disables a capability to access networks using the NAS protocol based upon the receiving the second message, stores an identity of the first network, and after storing, exploits the stored identity of the first network, by the UE, during a network selection process.

Abstract: A method includes transmitting, by a user equipment (UE), a registration request message to a network node according to a non-access stratum (NAS) protocol, the registration request message including a request for one or more single-network slice selection assistance informations (S-NSSAIs) in a first network. The UE receives a registration reject message from the network node, the registration reject message including a 5G system mobility management (5GMM) cause value #62 “no network slices available” indication. The UE disables N1 mode capability for the first network based upon the receiving the registration reject message, stores an identity of the first network, and, after storing, exploits the stored identity of the first network, by the UE, during a network selection process.
