1. A User Equipment (UE) comprising:
transmission and reception circuitry;
control circuitry; and
a storage,
wherein
the transmission and reception circuitry are configured to:
send a registration request message including requested Network Slice Selection Assistance Information (NSSAI) including a Single Network Slice Selection Assistance Information (S-NSSAI); and
receive a registration accept message including the S-NSSAI, a cause value indicating that the S-NSSAI is not available due to maximum number of UEs reached, and a back-off timer value, and
the control circuitry is configured to:
add the S-NSSAI in a rejected NSSAI regarding the S-NSSAI for which the maximum number of UEs has been reached in the storage;
start a timer with the back-off timer value; and
remove the S-NSSAI from the rejected NSSAI regarding the S-NSSAI for which the maximum number of UEs has been reached when the timer expires, and
the rejected NSSAI regarding the S-NSSAI for which the maximum number of UEs has been reached is information for each access type.
