Section: 12.7.1 Network Identifier (NID)
Content: A Stand-Alone Non-Public Network (SNPN) is identified by a combination of PLMN-Identifier (see clause 12.1) and Network Identifier (NID) (see 3GPP TS 23.501[ System architecture for the 5G System (5GS) ]  [119] clause 5.30.2). The NID shall consist of 11 hexadecimal digits, one digit for representing an assignment mode and 10 digits for a NID value, as shown in figure 12.7.1-1. Figure 12.7.1-1: Network Identifier (NID) The NID can be assigned using the following assignment models: a) Self-assignment: NIDs are chosen individually by SNPNs at deployment time; this assignment model is encoded by setting the assignment mode to value 1. b) Coordinated assignment: NIDs are assigned using one of the following two options: - option 1: the NID assigned such that it is globally unique independent of the PLMN ID used. Option 1 of this assignment model is encoded by setting the assignment mode to value 0. - option 2: the NID assigned such that the combination of the NID and the PLMN ID is globally unique. Option 2 of this assignment model is encoded by setting the assignment mode to value 2. The self-assignment NID model should not be used, if UE accesses SNPN using e.g. credentials from Credentials Holder via AAA Server, as specified in clause 5.30.2.1 in 3GPP TS 23.501[ System architecture for the 5G System (5GS) ]  [119]. Other Assignment mode values are spare, for future use.
