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