Registration request indicating failure of network
A wireless device receives from a base station of a first public land mobile network (PLMN) an indication of a failure of a second PLMN including a PLMN identifier of the second PLMN. The wireless device sends to an access and mobility management function, a registration request indicating the failure of the second PLMN. The registration request includes the PLMN identifier of the second PLMN, and one or more of a subscriber concealed identifier and a permanent equipment identifier of the wireless device.
1. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:
receive, from a base station of a first public land mobile network (PLMN), an indication of a failure of a second PLMN comprising a PLMN identifier of the second PLMN; and
send, to an access and mobility management function, a registration request indicating the failure of the second PLMN, the registration request comprising:
one or more of a subscriber concealed identifier (SUCI) and a permanent equipment identifier (PEI) of the wireless device; and
the PLMN identifier of the second PLMN.
2. The non-transitory computer-readable medium of claim 1 , wherein the indication of the failure of the second PLMN comprises an indication of a network disaster of the second PLMN.
3. The non-transitory computer-readable medium of claim 1 , wherein the instructions further cause the wireless device to receive, from the base station, a configuration message.
4. The non-transitory computer-readable medium of claim 3 , wherein the configuration message comprises the indication of the failure of the second PLMN.
5. The non-transitory computer-readable medium of claim 3 , wherein the configuration message comprises the PLMN identifier of the second PLMN.
6. The non-transitory computer-readable medium of claim 1 , wherein the instructions further cause the wireless device to determine based on the failure of the second PLMN, the first PLMN as a serving PLMN.
7. The non-transitory computer-readable medium of claim 1 , wherein the instructions further cause the wireless device to determine based on the failure of the second PLMN, the first PLMN as a serving PLMN during a network disaster of the second PLMN.
8. The non-transitory computer-readable medium of claim 1 , wherein the registration request is sent via the base station of the first PLMN.
9. The non-transitory computer-readable medium of claim 1 , wherein the registration request does not comprise a 5G globally unique temporary identifier (5G-GUTI) of the wireless device.
10. The non-transitory computer-readable medium of claim 1 , wherein sending the registration request is in response to the failure.
11. A non-transitory computer-readable medium comprising instructions that when executed by one or more processors of a base station of a first public land mobile network (PLMN), cause the base station to:
transmit, to a wireless device, an indication of a failure of a second PLMN comprising a PLMN identifier of the second PLMN; and
receive, from the wireless device, a registration request indicating the failure of the second PLMN, the registration request comprising:
one or more of a subscriber concealed identifier (SUCI) or a permanent equipment identifier (PEI) of the wireless device; and
the PLMN identifier of the second PLMN.
12. The non-transitory computer-readable medium of claim 11 , wherein the registration request indicates a network disaster of the second PLMN.
13. The non-transitory computer-readable medium of claim 11 , wherein the instructions further cause the base station to transmit, to the wireless device, a configuration message.
14. The non-transitory computer-readable medium of claim 13 , wherein the configuration message comprises the indication of the failure of the second PLMN.
15. The non-transitory computer-readable medium of claim 13 , wherein the configuration message comprises the PLMN identifier of the second PLMN.
16. The non-transitory computer-readable medium of claim 11 , wherein the instructions further cause the base station to send an access and mobility management function (AMF), the registration request.
17. The non-transitory computer-readable medium of claim 11 , wherein the first PLMN is a serving PLMN during a network disaster of the second PLMN.
18. The non-transitory computer-readable medium of claim 11 , wherein the instructions further cause the base station to transmit to the wireless device, a registration accept message.
19. The non-transitory computer-readable medium of claim 11 , wherein the registration request does not comprise a 5G globally unique temporary identifier (5G-GUTI) of the wireless device.
20. A system, comprising:
a base station of a first public land mobile network (PLMN); and
a wireless device, comprising:
one or more first processors; and
first memory storing instructions that, when executed by the one or more first processors, cause the wireless device to:
receive, from the base station, an indication of a failure of a second PLMN comprising a PLMN identifier of the second PLMN; and
send, to an access and mobility management function, a registration request indicating the failure of the second PLMN, the registration request comprising:
one or more of a subscriber concealed identifier (SUCI) and a permanent equipment identifier (PEI) of the wireless device; and
the PLMN identifier of the second PLMN,
wherein the base station comprises:
one or more second processors; and
second memory storing instructions that, when executed by the one or more second processors, cause the base station to:
transmit, to the wireless device, the indication of a failure of the second PLMN; and
receive, from the wireless device, the registration request indicating the failure of the second PLMN.
