This document covers the architectural requirements for 3GPP systems based on UTRAN, E-UTRAN and Iu mode GERAN. In particular it details the high level requirements for the Circuit Switched (CS) Domain and the stage 2 procedures that span more than one domain/subsystem. The reference model to which these procedures apply can be found within TS 23.002. In addition, A mode to Iu mode handover for CS services is addressed. Detailed architectural requirements within the subsystems are contained within the remainder of the 23 series of specifications e.g. the requirements for the Packet Switched (PS) domain are contained within TS 23.060, TS 23.401 and the requirements for the Bearer Independent CS Core Network are contained in TS 23.205.

3 Definitions, symbols and abbreviations p. 8
3.1 Definitions p. 8
For the purposes of the present document, the terms defined in TR 21.905 apply, in addition, the following terms apply:
3GPP PS Data Off Exempt Services:
For PDN Connection or PDU Session of type IP, up to two sets of operator services (i.e. the exempt services enumerated in clause 10.2 of TS 22.011, including the signalling used to enable such services) that are allowed even if the 3GPP PS Data Off status set to active in the UE by the user. One set is used when UE is in HPLMN, the other set is used when UE is roaming in VPLMN. For PDN connection of type non-IP or Ethernet, or PDU Session of type Ethernet or Unstructured, no 3GPP Data Off Exempt Service is defined.
In Iu mode:
see TR 21.905.
In A/Gb mode:
see TR 21.905.
RAN:
within this document, the term RAN (Radio Access Network) is used to refer to UTRAN and/or GERAN in Iu mode and/or E-UTRAN.
Restricted local operator services:
communication services provided by an operator that involve either automated or human assistance (e.g. credit card billing, directory assistance, customer care) for which successful authentication is not necessary.
For the purposes of the present document, the following terms and definitions given in TS 22.011 apply:
3GPP PS Data Off:
See TS 22.011.
