Network access management
A wireless device sends, to a network, a message indicating an enhanced steering of roaming (SOR) capability for network access information for one or more non-public networks (NPN). The wireless device receives, from the network, network access information comprising an identifier of a first NPN and a condition for whether the wireless device is allowed to access the first NPN. The wireless device sends, to the first NPN and based on the condition being met, a registration request message.
1. A method comprising:
sending, by a wireless device to an access and mobility management function (AMF) of a public land mobile network (PLMN), a non-access stratum (NAS) message comprising a parameter indicating that the wireless device is capable to support an enhanced steering of roaming (SOR) for selecting a standalone non-public network (SNPN), wherein in the enhanced SOR, the wireless device checks whether one or more location validity conditions for accessing one or more SNPN are met;
receiving, by the wireless device from the AMF, network access information comprising:
an identifier of a first SNPN; and
a location validity condition indicating where the wireless device is allowed to access the first SNPN, wherein the location validity condition comprises one or more tracking areas; and
sending, by the wireless device to the first SNPN and upon the location validity condition being met, a registration request message.
2. The method of claim 1 , wherein the parameter indicates that the wireless device supports handling the network access information.
3. The method of claim 1 , wherein the NAS message comprises at least one of:
an identity of the wireless device;
one or more identifiers of one or more requested network slices; or
an identity of the first SNPN.
4. The method of claim 3 , wherein the wireless device receives the network access information in response to sending the NAS message.
5. The method of claim 3 , wherein the first NAS message comprises a first registration request message.
6. The method of claim 1 , wherein the network access information comprises a time period condition during which the wireless device is allowed to access the first SNPN.
7. The method of claim 6 , wherein the time period condition comprises at least one of:
a start time from when the wireless device is allowed to access the first SNPN;
an end time from when the wireless device is not allowed to access the first SNPN; or
a time duration during which the wireless device is allowed to access the first SNPN.
8. 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:
send, to an access and mobility management function (AMF) of a public land mobile network (PLMN), a non-access stratum (NAS) message comprising a parameter indicating that the wireless device is capable to support an enhanced steering of roaming (SOR) for selecting a standalone non-public networks (SNPN), wherein in the enhanced SOR, the wireless device checks whether one or more location validity conditions for accessing one or more SNPN are met;
receive, from the AMF, network access information comprising:
an identifier of a first SNPN; and
a location validity condition indicating where the wireless device is allowed to access the first SNPN, wherein the location validity condition comprises one or more tracking areas; and
send, to the first SNPN and upon the location validity condition being met, a registration request message.
9. The wireless device of claim 8 , wherein the parameter indicates that the wireless device supports handling the network access information.
10. The wireless device of claim 8 , wherein the NAS comprises at least one of:
an identity of the wireless device;
one or more identifiers of one or more requested network slices; or
an identity of the first SNPN.
11. The wireless device of claim 10 , wherein the wireless device receives the network access information in response to sending the NAS message.
12. The wireless device of claim 10 , wherein the NAS message comprises a first registration request message.
13. The wireless device of claim 8 , wherein the network access information comprises a time period condition during which the wireless device is allowed to access the first SNPN.
14. The wireless device of claim 13 , wherein the time period condition comprises at least one of:
a start time from when the wireless device is allowed to access the first SNPN;
an end time from when the wireless device is not allowed to access the first SNPN; or
a time duration during which the wireless device is allowed to access the first SNPN.
15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a wireless device to:
send, to an access and mobility management function (AMF) of a public land mobile network (PLMN), a non-access stratum (NAS) message comprising a parameter indicating that the wireless device is capable to support an enhanced steering of roaming (SOR) for selecting a standalone non-public network (SNPN), wherein in the enhanced SOR, the wireless device checks whether one or more location validity conditions for accessing one or more SNPN are met;
receive, from the AMF, network access information comprising:
an identifier of a first SNPN; and
a location validity condition indicating where the wireless device is allowed to access the first SNPN, wherein the location validity condition comprises one or more tracking areas; and
send, to the first SNPN and upon the location validity condition being met, a registration request message.
16. The computer-readable medium of claim 15 , wherein the parameter indicates that the wireless device supports handling the network access information.
17. The computer-readable medium of claim 15 , wherein the NAS message comprises at least one of:
an identity of the wireless device;
one or more identifiers of one or more requested network slices; or
an identity of the first SNPN.
18. The computer-readable medium of claim 17 , wherein the wireless device receives the network access information in response to sending the NAS message.
19. The computer-readable medium of claim 17 , wherein the NAS message comprises a first registration request message.
20. The computer-readable medium of claim 15 , wherein the network access information comprises a time period condition during which the wireless device is allowed to access the first SNPN.
