== Subscription Permanent Identifier (SUPI) § 2.2A ==

The SUPI is a globally unique 5G Subscription Permanent Identifier allocated to each subscriber in the 5G System. It is defined in clause 5.9.2 of 3GPP TS 23.501.

The SUPI is defined as:
* a SUPI type: in this release of the specification, it may indicate an IMSI, a Network Specific Identifier (NSI), a Global Line Identifier (GLI) or a Global Cable Identifier (GCI); and
* dependent on the value of the SUPI type:
** an IMSI as defined in clause 2.1;
** a Network Specific Identifier (NSI), taking the form of a Network Access Identifier (NAI) as defined in clause 28.7.2;
** a Global Cable Identifier (GCI) taking the form of a NAI as defined in clause 28.15.2;
** a Global Line Identifier (GLI) taking the form of an NAI as defined in clause 28.16.2.
:NOTE:	Depending on the protocol used to convey the SUPI, the SUPI type can take different formats.

See clauses 4.7.2, 4.7.3 and 4.7.4 of 3GPP TS 23.316 for details on which types of SUPI are supported by 5G-BRG, FN-BRG, 5G-CRG and FN-CRG.
