Section: 12.6 Shared Network Area Identifier
Content: The Shared Network Area Identifier (SNA-Id) is used to identify an area consisting of one or more Location Areas. Such an area is called a Shared Network Area and can be used to grant access rights to parts of a Shared Network to a UE in connected mode (see 3GPP TS 25.401[ None ]  [39]). The Shared Network Area Identifier consists of the PLMN-Id followed by the Shared Network Area Code (SNAC). - SNA-Id = PLMN-Id || SNAC The SNAC is defined by the operator. For the syntax description and the use of this identifier in RANAP signalling, see 3GPP TS 25.413[ UTRAN Iu interface Radio Access Network Application Part (RANAP) signalling ]  [17].
