Figure 8.2.4-1: Network Instance
The Network instance field shall be encoded as an OctetString and shall contain an identifier which uniquely identifies a particular Network instance (e.g. PDN instance) in the UP function. It may be encoded as a Domain Name or an Access Point Name (APN) as per clause 9.1 of 3GPP TS 23.003 [2]. In the latter case, the PDN Instance field may contain the APN Network Identifier only or the full APN with both the APN Network Identifier and the APN Operator Identifier as specified in 3GPP TS 23.003 [2] clauses 9.1.1 and 9.1.2.
NOTE: The APN field is not encoded as a dotted string as commonly used in documentation.
