WE CLAIM:
1. A method in a user equipment (UE) supporting registration using third generation
partnership project (3GPP) access and using non-3GPP access, the method comprising:
storing (220), by the UE, first emergency information received using first
registration procedures with a first public land mobile network (PLMN), the first
emergency information comprising a first extended local emergency number list, and
the first emergency information received from the first PLMN;
receiving (240), by the UE, a REGISTRATION ACCEPT message using
second registration procedures with a second PLMN via non-3GPP access, the
REGISTRATION ACCEPT message excluding an extended local emergency number
list; and
discarding (270), by the UE, the first emergency information after receiving the
REGISTRATION ACCEPT message from the second PLMN if at least one condition
of one or more conditions is met,
wherein a first condition of the one or more conditions comprises the UE having
received the REGISTRATION ACCEPT message from the second PLMN that is in a
country different from the country of the first PLMN.
2. The method as claimed in claim 1, wherein the first emergency information comprises
an extended emergency number list validity (EENLV) indicator comprising a first
indication, and the first indication indicates that the first extended local emergency
number list is valid in the first PLMN where the list is received.
3. The method as claimed in claim 2, wherein a second condition of the one or more
conditions comprises the UE having received the REGISTRATION ACCEPT message
from the second PLMN different from the first PLMN.
4. The method as claimed in claim 1, wherein discarding the first emergency information
if at least one condition of the one or more conditions is met comprises keeping the first
emergency information unless at least one condition of the one or more conditions is
met.
5. The method as claimed in claim 1, wherein the registration procedures with the first
PLMN comprise registration procedures via 3GPP access.

6. The method as claimed in claim 1, comprising storing, by the UE, an indication of an
access type via which the first emergency information was received.
7. The method as claimed in claim 6, wherein a third condition of the one or more
conditions comprises the indication of the access type matching non-3GPP access.
8. The method as claimed in claim 1, wherein the first registration procedures comprise
registering a presence of the UE by means of at least one of a tracking area update
procedure, an attach procedure in the evolved packet system (EPS), or a registration
procedure in the 5G system (5GS).
9. The method as claimed in claim 1, wherein the second registration procedures comprise
registering a presence of the UE by means of a registration procedure in the 5G system
(5GS).
10. A user equipment (UE) (3200) supporting registration using third generation
partnership project (3GPP) access and using non-3GPP access, the UE comprising:
a memory; and
a processor (3238) coupled to the memory, the processor configured to:
store first emergency information received using first registration procedures
with a first public land mobile network (PLMN), the first emergency information
comprising a first extended local emergency number list, and the first emergency
information received from the first PLMN;
receive a REGISTRATION ACCEPT message using second registration
procedures with a second PLMN via non-3GPP access, the REGISTRATION ACCEPT
message excluding an extended local emergency number list; and
discard the first emergency information after receiving the REGISTRATION ACCEPT
message from the second PLMN if at least one condition of one or more conditions is
met,
wherein a first condition of the one or more conditions comprises the UE having
received the REGISTRATION ACCEPT message from the second PLMN that is in a
country different from the country of the first PLMN.

11. The UE as claimed in claim 10, wherein the first emergency information comprises an
extended emergency number list validity (EENLV) indicator comprising a first
indication, and the first indication indicates that the first extended local emergency
number list is valid in the first PLMN where the list is received.
12. The UE as claimed in claim 11, wherein a second condition of the one or more
conditions comprises the UE having received the REGISTRATION ACCEPT message
from the second PLMN different from the first PLMN.
13. The UE as claimed in claim 10, wherein discarding the first emergency information if
at least one condition of the one or more conditions is met comprises keeping the first
emergency information unless at least one condition of the one or more conditions is
met.
14. The UE as claimed in claim 10, comprising storing, by the UE, an indication of an
access type via which the first emergency information was received, wherein a third
condition of the one or more conditions comprises the indication of the access type
matching non-3GPP access.
15. The UE as claimed in claim 10, wherein the first registration procedures comprise
registering a presence of the UE by means of at least one of a tracking area update
procedure, an attach procedure in the evolved packet system (EPS), or a registration
procedure in the 5G system (5GS).
