Abstract
A new radio (NR) user equipment (UE) registration procedure that may be executed by a UE and a network is disclosed, resulting in a UE registration that may be more efficient than existing UE registration procedures. For example, the UE registration procedure may utilize messaging between an extensible authentication protocol (EAP) component and a non-access stratum (NAS) component to abort the registration procedure when a non-recoverable EAP failure occurs, or suspend or re-start a NAS registration timer when a recoverable EAP failure occurs.
Claims30
A method of wireless communications at a user equipment (UE), comprising:
- initiating a security procedure for registering the UE at a first network, wherein the UE implements an extensible authentication protocol (EAP) component and a non-access stratum (NAS) component;
- starting a NAS registration timer at the NAS component in response to initiating the security procedure, wherein an expiration of the NAS registration timer is configured to cause the NAS component to abort the security procedure;
- determining an EAP failure in the security procedure;
- determining whether the EAP failure is a recoverable type failure that is recoverable by retrying at least a portion of the security procedure or a not-recoverable type failure that is not recoverable by retrying any portion of the security procedure;
- aborting the security procedure in response to the EAP failure being the not-recoverable type failure;
- and
- suspending or re-starting the NAS registration timer in response to the EAP failure being the recoverable type failure.
4 more elements
A user equipment (UE), comprising:
- a memory;
- and
- at least one processor in communication with the memory, wherein the at least one processor is configured to:
- initiate a security procedure for registering the UE at a first network, wherein the UE implements an extensible authentication protocol (EAP) component and a non-access stratum (NAS) component;
- start a NAS registration timer at the NAS component in response to initiating the security procedure, wherein an expiration of the NAS registration timer is configured to cause the NAS component to abort the security procedure;
- determine an EAP failure in the security procedure;
- determine whether the EAP failure is a recoverable type failure that is recoverable by retrying at least a portion of the security procedure or a not-recoverable type failure that is not recoverable by retrying any portion of the security procedure;
- abort the security procedure in response to the EAP failure being the not-recoverable type failure;
- and
- suspend or re-start the NAS registration timer in response to the EAP failure being the recoverable type failure.

4 more elements
A non-transitory computer-readable medium storing computer code executable by a processor of a user equipment (UE), wherein the computer code, when executed by the processor, causes the processor to:
- initiate a security procedure for registering the UE at a first network, wherein the UE implements an extensible authentication protocol (EAP) component and a non-access stratum (NAS) component;
- start a NAS registration timer at the NAS component in response to initiating the security procedure, wherein an expiration of the NAS registration timer is configured to cause the NAS component to abort the security procedure;
- determine an EAP failure in the security procedure;
- determine whether the EAP failure is a recoverable type failure that is recoverable by retrying at least a portion of the security procedure or a not-recoverable type failure that is not recoverable by retrying any portion of the security procedure;
- abort the security procedure in response to the EAP failure being the not-recoverable type failure;
- and
- suspend or re-start the NAS registration timer in response to the EAP failure being the recoverable type failure.
