Slice and/or subscriber identification module device lock
A method, apparatus, and system are provided for slice and/or subscriber identification module (SIM) device locking/unlocking. In one embodiment, a method implemented in a user equipment, UE, having one or more subscriber identification module, SIM, is provided. The method includes activating one or more subscriber identification module, SIM for a UE. The method includes, as a result of activating, initiating a request to register the UE with a network, and receiving allowed Network Slice Selection Assistance Information, NSSAI. The method includes associating received one or more single-NSSAI, S-NSSAI, indicated by the allowed NSSAI to one of the one or more SIM in the UE according to a policy. The method includes using one of the one or more S-NSSAI associated to one of the activated SIM to establish a Packet Data Unit, PDU, session.
1. A method performed by a user equipment, (UE) having one or more subscriber identification modules (SIMs), the method comprising:
activating, via an activation code or an activation pattern, one or more SIMs for a UE;
as a result of activating, initiating a request to register the UE with a network, and receiving allowed Network Slice Selection Assistance Information (NSSAI);
associating received one or more single-NSSAI (S-NSSAI) indicated by the allowed NSSAI to one of the one or more SIMs in the UE according to a policy so that,
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, all of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs, or
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, a subset of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs according to the policy;
using one of the one or more S-NSSAI associated to one of the activated one or more SIMs to establish a Packet Data Unit (PDU) session; and
one SIM having multiple activation codes or activation patterns, and each activation code or activation pattern being associated with a corresponding subset of allowed NSSAI or all the allowed NSSAI.
2. The method of claim 1 , wherein the policy is one of a pre-configured UE rule and a UE Route Selection Policy (URSP) rule.
3. The method of claim 1 , further comprising:
informing an application that the association of the application to the PDU session failed if at least one of:
the one of the one or more S-NSSAI is associated to an inactive SIM; and
the one of the one or more S-NSSAI is not associated to the activated one or more SIMs.
4. The method of claim 1 , wherein the activation code or activation pattern activates multiple SIMs, and the associating of the received one or more S-NSSAI indicated by the allowed NSSAI to one of the one or more SIMs further includes associating all or a subset of the S-NSSAI indicated by the allowed NSSAI per SIM.
5. The method of claim 1 , wherein the activation pattern is one of a swipe pattern, a PIN or a biometric pattern.
6. The method of claim 1 , wherein the activation code or activation pattern is configured by a user.
7. The method of claim 1 , wherein the activation code or activation pattern is a display unlock pattern.
8. The method of claim 1 , further comprising inputting a display screen unlock pattern by a user to switch between at least one SIM and network slices, a network slice being identified by an S-NSSAI.
9. The method of claim 1 , wherein establishing the PDU session fails if the S-NSSAI used to establish the PDU session is not associated with the activated one or more SIMs.
10. A user equipment (UE) with one or more subscriber identification modules (SIMs) and comprising processing circuitry, the processing circuitry configured to cause the UE to:
activate, via an activation code or an activation pattern, one or more SIMs for a UE;
as a result of activating, initiate a request to register the UE with a network, and receive allowed Network Slice Selection Assistance Information (NSSAI);
associate received one or more single-NSSAI (S-NSSAI) indicated by the allowed NSSAI to one of the one or more SIMs in the UE according to a policy so that,
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, all of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs, or
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, a subset of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs according to the policy;
use one of the one or more S-NSSAI associated to one of the activated one or more SIMs to establish a Packet Data Unit (PDU) session; and
one SIM having multiple activation codes or activation patterns, and each activation code or activation pattern being associated to a corresponding subset of allowed NSSAI or all the allowed NSSAI.
11. The user equipment of claim 10 , wherein the policy is one of a pre-configured UE rule and a UE Route Selection Policy (URSP) rule.
12. The user equipment of claim 10 , wherein the processing circuitry is further configured to cause the UE to:
inform an application that the association of the application to the PDU session failed if at least one of:
the one of the one or more S-NSSAI is associated to an inactive SIM; and
the one of the one or more S-NSSAI is not associated to the activated one or more SIMs.
13. A non-transitory computer readable storage medium containing a computer program comprising instructions which when executed on at least one processor causes the at least one processor to carry out a method, the method comprising:
activating, via an activation code or an activation pattern, one or more subscriber identification modules (SIMs) for a user equipment (UE);
as a result of activating, initiating a request to register the UE with a network, and receiving allowed Network Slice Selection Assistance (NSSAI);
associating received one or more single-NSSAI (S-NSSAI) indicated by the allowed NSSAI to one of the one or more SIMs in the UE according to a policy so that,
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, all of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs, or
as a result of the activation of the one or more SIMs via the activation code or the activation pattern, a subset of the S-NSSAI indicated by the allowed NSSAI are associated to the activated one or more SIMs according to the policy; and
using one of the one or more S-NSSAI associated to one of the activated one or more SIMs to establish a Packet Data Unit (PDU) session,
one SIM having multiple activation codes or activation patterns, and each activation code or activation pattern being associated to a corresponding subset of allowed NSSAI or all the allowed NSSAI.
