upon expiration of the timer, re-enabling the N1 mode capability at the user equipment; and
in an instance in which a counter value for the particular counter of the one or more counters maintained at the user equipment is below a predetermined threshold, removing the SNPN identity of the particular SNPN associated with the entry used for sending the request to the particular SNPN from the list including the of one or more SNPN identities maintained at the user equipment.
