Abstract
Method and apparatus are provided for priority fallback of SUCI calculation. In accordance with some implementation, a UE may transmit, in response to receiving an indication of authentication failure for a first SUCI based on a first SUCI parameter, a second SUCI based on a second SUCI parameter different from the first SUCI parameter. In accordance with some implementation, the UE may further transmit a SUCI with NULL SUCI parameter if the UE determines all SUCI parameters supported by the UE has been rejected by the network.
Claims24
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a network entity, a request message for a subscription concealed identifier (SUCI);
- transmitting, to the network entity, a first SUCI based on a first SUCI parameter from a plurality of SUCI parameters available to the UE, wherein the first SUCI parameter is a highest priority SUCI parameter in the plurality of SUCI parameters;
- receiving, from the network entity, a rejection message including an indication of authentication failure;
- and
- transmitting, to the network entity and in response to receiving the rejection message, a second SUCI based on a second SUCI parameter from the plurality of SUCI parameters, wherein the second SUCI parameter is different from the first SUCI parameter and based at least in part on determining whether all SUCI parameters supported by the UE in the plurality of SUCI parameters have been rejected by the network entity.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled with the memory and configured to:
- receive, from a network entity, a request message for a subscription concealed identifier (SUCI);
- transmit, to the network entity, a first SUCI based on a first SUCI parameter from a plurality of SUCI parameters available to the UE, wherein the first SUCI parameter is a highest priority SUCI parameter in the plurality of SUCI parameters;
- receive, from the network entity, a rejection message including an indication of authentication failure;
- and
- transmit, to the network entity and in response to receiving the rejection message, a second SUCI based on a second SUCI parameter from the plurality of SUCI parameters, wherein the second SUCI parameter is different from the first SUCI parameter and based at least in part on a determination of whether all SUCI parameters supported by the UE in the plurality of SUCI parameters have been rejected by the network entity.
An apparatus for wireless communication performed by a user equipment (UE), comprising:
- means for receiving, from a network entity, a request message for a subscription concealed identifier (SUCI);
- means for transmitting, to the network entity, a first SUCI based on a first SUCI parameter from a plurality of SUCI parameters available to the UE, wherein the first SUCI parameter is a highest priority SUCI parameter in the plurality of SUCI parameters;
- means for receiving, from the network entity, a rejection message including an indication of authentication failure;
- and
- means for transmitting, to the network entity and in response to receiving the rejection message, a second SUCI based on a second SUCI parameter from the plurality of SUCI parameters, wherein the second SUCI parameter is different from the first SUCI parameter and based at least in part on a determination of whether all SUCI parameters supported by the UE in the plurality of SUCI parameters have been rejected by the network entity.
A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:
- receive, from a network entity, a request message for a subscription concealed identifier (SUCI);
- transmit, to the network entity, a first SUCI based on a first SUCI parameter from a plurality of SUCI parameters available to a user equipment (UE), wherein the first SUCI parameter is a highest priority SUCI parameter in the plurality of SUCI parameters;
- receive, from the network entity, a rejection message including an indication of authentication failure;
- and
- transmit, to the network entity and in response to receiving the rejection message, a second SUCI based on a second SUCI parameter from the plurality of SUCI parameters, wherein the second SUCI parameter is different from the first SUCI parameter and based at least in part on a determination of whether all SUCI parameters supported by the UE in the plurality of SUCI parameters have been rejected by the network entity.
