name: SNPN
full_form: Stand-Alone Non-Public Network
context: 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.
description: A Stand-Alone Non-Public Network (SNPN) is a type of network that operates independently and is not part of the traditional public land mobile network (PLMN). It is identified by a unique combination of PLMN-Identifier and Network Identifier (NID), which consists of an assignment mode and a 10-digit NID value. The NID can be assigned using self-assignment, coordinated assignment with globally unique NIDs, or coordinated assignment with unique combinations of NID and PLMN ID. SNPNs are used for specific use cases such as private networks for industries, campuses, or events.
explanation: SNPN is classified as a NetworkFunction_Group because it represents a collective set of network functions that work together to deliver specific telecommunications capabilities for non-public networks. It operates independently and has its own unique identification and assignment models, which distinguishes it from other network function groups.
