Abstract
Certain aspects provide a method for wireless communication. The method generally includes deriving a network specific identifier (NSI) in a network access identifier (NAI) format, the NSI including a network identifier (NID) stored at the UE, generating a subscription concealed identifier (SUCI) based on the NSI for authentication of the UE with a non-public network (NPN), and sending the SUCI to a network entity for the authentication of the UE with the NPN.
Claims25
A method for wireless communication by a user-equipment (UE), comprising:
- determining that a universal subscriber identity module (USIM) of the UE comprises an international mobile subscriber identity (IMSI) comprising information that matches a subscription permanent identifier (SUPI) of a non-public network (NPN) or that matches a public land and mobile network identifier (PLMN ID) of an identifier of the NPN stored at the UE;
- deriving a network specific identifier (NSI) in a network access identifier (NAI) format, based on the determination, the NSI including a network identifier (NID);
- generating a subscription concealed identifier (SUCI) based on the NSI;
- and
- sending the SUCI to a network entity for authentication of the UE with the NPN.
An apparatus for wireless communication by a user-equipment (UE), comprising:
- a memory;
- and
- one or more processors coupled to the memory, the memory and the one or more processors being configured to:
- determine that a universal subscriber identity module (USIM) of the UE comprises an international mobile subscriber identity (IMSI) comprising information that matches a subscription permanent identifier (SUPI) of a non-public network (NPN) or that matches a public land and mobile network identifier (PLMN ID) of an identifier of the NPN stored at the UE;
- derive a network specific identifier (NSI) in a network access identifier (NAI) format, based on the determination, the NSI including a network identifier (NID);
- generate a subscription concealed identifier (SUCI) based on the NSI;
- and
- send the SUCI to a network entity for authentication of the UE with the NPN.
An apparatus for wireless communication by a user-equipment (UE), comprising:
- means for determining that a universal subscriber identity module (USIM) of the UE comprises an international mobile subscriber identity (IMSI) comprising information that matches a subscription permanent identifier (SUPI) of a non-public network (NPN) or that matches a public land and mobile network identifier (PLMN ID) of an identifier of the NPN stored at the UE;
- means for deriving a network specific identifier (NSI) in a network access identifier (NAI) format, based on the determination, the NSI including a network identifier (MD);
- means for generating a subscription concealed identifier (SUCI) based on the NSI;
- and
- means for sending the SUCI to a network entity for authentication of the UE with the NPN.
A non-transitory computer-readable medium having instructions stored thereon to cause a user-equipment (UE) to:
- determine that a universal subscriber identity module (USIM) of the UE comprises an international mobile subscriber identity (IMSI) comprising information that matches a subscription permanent identifier (SUPI) of a non-public network (NPN) or that matches a public land and mobile network identifier (PLMN ID) of an identifier of the NPN stored at the UE;
- derive a network specific identifier (NSI) in a network access identifier (NAI) format, based on the determination, the NSI including a network identifier (NID);
- generate a subscription concealed identifier (SUCI) based on the NSI;
- and
- send the SUCI to a network entity for authentication of the UE with the NPN.
