User equipment (UE) and communication control method performed by UE
A User Equipment (UE) includes a transmission and reception unit, a storage unit, and a controller, in which the transmission and reception unit is configured to receive Allowed Network Slice Selection Assistance Information (NSSAI) and one or more first mapped Single Network Slice Selection Assistance Information (S-NSSAI) for the Allowed NSSAI, and unless the storage unit stores an S-NSSAI associated with second mapped S-NSSAI in rejected NSSAI and the second mapped S-NSSAI is not included in the one or more first mapped S-NSSAI for the Allowed NSSAI, the controller removes an S-NSSAI included in the Allowed NSSAI from the rejected NSSAI stored in the storage unit.
1 . A User Equipment (UE) comprising:
a transmission and reception circuitry;
at least one processor; and
a storage coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor,
cause the transmission and reception circuitry to receive Allowed Network Slice Selection Assistance Information (NSSAI) and one or more first mapped Single Network Slice Selection Assistance Information (S-NSSAI) for the Allowed NSSAI,
wherein:
the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to remove an S-NSSAI included in the Allowed NSSAI from rejected NSSAI stored in the storage, unless the storage stores the S-NSSAI associated with one or more second mapped S-NSSAI in the rejected NSSAI and the one or more second mapped S-NSSAI is not included in the one or more first mapped S-NSSAI for the Allowed NSSAI,
the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to remove one or more S-NSSAI included in the one or more first mapped S-NSSAI for the Allowed NSSAI from the one or more second mapped S-NSSAI for the rejected NSSAI stored in the storage, and
the one or more computer-executable instructions, when executed by the at least one processor, further cause the transmission and reception circuitry to transmit a requested NSSAI including an S-NSSAI that is included in the Allowed NSSAI.
2 . A User Equipment (UE) comprising:
a transmission and reception circuitry;
at least one processor; and
a storage coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor,
cause the transmission and reception circuitry to receive Allowed Network Slice Selection Assistance Information (NSSAI) and one or more first mapped Single Network Slice Selection Assistance Information (S-NSSAI) for the Allowed NSSAI,
wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to remove an S-NSSAI included in the Allowed NSSAI from rejected NSSAI stored in the storage, unless the S-NSSAI included in the rejected NSSAI stored in the storage is associated with one or more second mapped S-NSSAI in the rejected NSSAI and the one or more second mapped S-NSSAI is not included in the one or more first mapped S-NSSAI for the Allowed NSSAI,
the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to remove one or more S-NSSAI included in the one or more first mapped S-NSSAI for the Allowed NSSAI from the one or more second mapped S-NSSAI for the rejected NSSAI stored in the storage, and
the one or more computer-executable instructions, when executed by the at least one processor, further cause the transmission and reception circuitry to transmit a requested NSSAI including an S-NSSAI that is included in the Allowed NSSAI.
3 . The UE according to claim 1 ,
wherein in a case that the storage stores the S-NSSAI associated with the one or more second mapped S-NSSAI in the rejected NSSAI, and in a case that the one or more second mapped S-NSSAI is not included in the one or more first mapped S-NSSAI for the Allowed NSSAI, the one or more computer-executable instructions, when executed by the at least one processor, cause the UE to not remove the S-NSSAI included in the Allowed NSSAI from the rejected NSSAI stored in the storage.
4 . The UE according to claim 2 ,
wherein in a case that the S-NSSAI included in the rejected NSSAI stored in the storage is associated with the one or more second mapped S-NSSAI in the rejected NSSAI, and in a case that the one or more second mapped S-NSSAI is not included in the one or more first mapped S-NSSAI for the Allowed NSSAI, the one or more computer-executable instructions, when executed by the at least one processor, cause the UE to not remove the S-NSSAI included in the Allowed NSSAI from the rejected NSSAI stored in the storage.
5 . A communication control method performed by a User Equipment (UE), the communication control method comprising:
receiving Allowed Network Slice Selection Assistance Information (NSSAI) and one or more first mapped Single Network Slice Selection Assistance Information (S-NSSAI) for the Allowed NSSAI;
removing an S-NSSAI included in the Allowed NSSAI from rejected NSSAI stored in the UE, unless the S-NSSAI included in the rejected NSSAI stored in the UE is associated with one or more second mapped S-NSSAI in the rejected NSSAI and the one or more second mapped S-NSSAI is not included in the one or more first mapped S-NSSAI for the Allowed NSSAI;
removing one or more S-NSSAI included in the one or more first mapped S-NSSAI for the Allowed NSSAI from the one or more second mapped S-NSSAI for the rejected NSSAI stored in the UE; and
transmitting a requested NSSAI including an S-NSSAI that is included in the Allowed NSSAI.
