Network slice provision management
A wireless device receives, from a core network node, one or more messages comprising an identifier of a network slice, an identifier of an alternative network slice mapped to the network slice, and an identifier of a network slice group associated with the alternative network slice.
1 . A method comprising:
receiving, by a wireless device from a core network node, a message comprising:
an identifier of an allowed network slice;
an identifier of an alternative network slice mapped to the allowed network slice; and
information of a network slice group associated with the alternative network slice; and
sending, by the wireless device to the core network node, a registration request message comprising one of:
the identifier of the allowed network slice; or
the identifier of the alternative network slice.
2 . The method of claim 1 , further comprising receiving, by the wireless device from a base station, an identifier of the network slice group.
3 . The method of claim 2 , wherein the base station is a second base station, and the message is received from a first base station different from the second base station.
4 . The method of claim 2 , wherein the identifier of the network slice group is received from the base station in a system information and/or a system information block (SIB).
5 . The method of claim 2 , further comprising sending, by the wireless device to the base station, the identifier of the alternative network slice.
6 . The method of claim 5 , wherein the identifier of the alternative network slice is sent in a non-access stratum (NAS) message.
7 . The method of claim 5 , wherein the sending the identifier of the alternative network slice is based on the receiving the identifier of the network slice group.
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:
receive, from a core network node, a message comprising:
an identifier of an allowed network slice;
an identifier of an alternative network slice mapped to the allowed network slice; and
information of a network slice group associated with the alternative network slice; and
send, to the core network node, a registration request message comprising one of:
the identifier of the allowed network slice; or
the identifier of the alternative network slice.
9 . The wireless device of claim 8 , wherein the instructions further cause the wireless device to receive, from a base station, an identifier of the network slice group.
10 . The wireless device of claim 9 , wherein the base station is a second base station, and the message is received from a first base station different from the second base station.
11 . The wireless device of claim 9 , wherein the identifier of the network slice group is received from the base station in a system information and/or a system information block (SIB).
12 . The wireless device of claim 9 , wherein the instructions further cause the wireless device to send, to the base station, the identifier of the alternative network slice.
13 . The wireless device of claim 12 , wherein the identifier of the alternative network slice is sent in a non-access stratum (NAS) message.
14 . The wireless device of claim 12 , wherein the sending the identifier of the alternative network slice is based on the receiving the identifier of the network slice group.
15 . 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 core network node, a message comprising:
an identifier of an allowed network slice;
an identifier of an alternative network slice mapped to the allowed network slice; and
information of a network slice group associated with the alternative network slice; and
send, to the core network node, a registration request message comprising one of:
the identifier of the allowed network slice; or
the identifier of the alternative network slice.
16 . The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the wireless device to receive, from a base station, an identifier of the network slice group.
17 . The non-transitory computer-readable medium of claim 16 , wherein the base station is a second base station, and the message is received from a first base station different from the second base station.
18 . The non-transitory computer-readable medium of claim 16 , wherein the identifier of the network slice group is received from the base station in a system information and/or a system information block (SIB).
19 . The non-transitory computer-readable medium of claim 16 , wherein the instructions further cause the wireless device to send, to the base station, the identifier of the alternative network slice.
20 . The non-transitory computer-readable medium of claim 19 , wherein the identifier of the alternative network slice is sent in a non-access stratum (NAS) message.
