1. A method, comprising:
receiving, by a processor of an apparatus, a 5th generation session management (5GSM) message with a back-off timer from a network node of a wireless network;
starting, by the processor, the back-off timer;
associating, by the processor, the back-off timer with a mapped home public land mobile network (HPLMN) single-network slice selection assistance information (S-NSSAI) part of a valid S-NSSAI value provided by the apparatus to the wireless network; and
in an event that the apparatus is in a roaming scenario:
determining, by the processor, whether a mapped HPLMN S-NSSAI of a protocol data unit (PDU) session of the 5GSM message is same as the mapped HPLMN S-NSSAI part of the valid S-NSSAI value associated with the back-off timer; and
stopping, by the processor, the back-off timer responsive to a positive result from the determining; in an event that the apparatus is in a non-roaming scenario:
determining, by the processor, whether a mapped HPLMN S-NSSAI or serving PLMN S-NSSAI of the PDU session of the 5GSM message is same as the mapped HPLMN S-NSSAI part of the valid S-NSSAI value associated with the back-off timer; and
stopping, by the processor, the back-off timer responsive to a positive result from the determining.
