Full title and description
Information technology — Telecommunications and information exchange between systems — Private Integrated Services Network — Inter-exchange signalling protocol — Wireless Terminal Authentication supplementary services (ISO/IEC 15433:2003). This international standard specifies the signalling protocol to support Wireless Terminal Authentication supplementary services (SS-WTAT and SS-WTAN) at the Q reference point between Private Integrated services Network eXchanges (PINXs) within a Private Integrated Services Network (PISN).
Abstract
ISO/IEC 15433:2003 defines stage‑3 signalling protocol details for SS‑WTAT (authentication of a wireless terminal user) and SS‑WTAN (authentication of the PISN to a served wireless terminal), using challenge‑response mechanisms. The standard specifies protocol messages, interactions with other supplementary services and conformance artefacts; it does not mandate specific authentication algorithms.
General information
- Status: Published (International Standard, Edition 2.0).
- Publication date: 21 March 2003 (publication date shown by IEC webstore / 2003 edition).
- Publisher: Joint ISO/IEC publication (prepared by ISO/IEC JTC 1/SC 6).
- ICS / categories: 33.040.35 (Telecommunications signalling and exchange).
- Edition / version: Edition 2.0 (2003).
- Number of pages: 48 pages (base publication).
Scope
The standard applies to PINXs that interconnect to form a PISN and specifies the Q‑point signalling protocol necessary to support the Wireless Terminal Authentication supplementary services SS‑WTAT and SS‑WTAN. It covers message formats, signalling procedures, interactions with other supplementary services and conformance artefacts (PICS, ASN.1 and SDL representations) while excluding the choice of authentication algorithms.
Key topics and requirements
- Definition of signalling messages and procedures for SS‑WTAT (authenticate WTM user) and SS‑WTAN (authenticate PISN to user).
- Use of challenge‑response authentication exchanges at the Q reference point.
- Specification of interactions between WT authentication services and other supplementary services and additional network features.
- Conformance support artifacts: Protocol Implementation Conformance Statement (PICS) proforma, ASN.1 module listings and SDL representations (informative/normative as indicated).
- Explicit statement that authentication algorithms themselves are outside the scope — the standard defines signalling, not cryptographic primitives.
Typical use and users
Primary users are telecommunications standards implementers, PISN / PBX vendors, equipment manufacturers, network operators and test laboratories implementing or verifying inter‑exchange signalling for wireless terminal authentication. The standard is used to design, implement and test Q‑point signalling behaviors when providing WT authentication supplementary services.

FAQ
Q: What is this standard?
A: ISO/IEC 15433:2003 is an international standard that specifies the inter‑exchange signalling protocol for Wireless Terminal Authentication supplementary services (SS‑WTAT and SS‑WTAN) at the Q reference point between PINXs in a Private Integrated Services Network (PISN).
Q: What does it cover?
A: It covers stage‑3 signalling protocol definitions (messages, procedures and interactions) to support authentication exchanges (challenge‑response) between exchanges and terminals; it also provides conformance artefacts such as PICS proformas and ASN.1/SDL representations. It does not mandate cryptographic algorithms.
Q: Who typically uses it?
A: Equipment vendors, PBX/PISN implementers, network operators and test laboratories use the standard to implement or validate inter‑exchange WT authentication behaviours and signalling conformance.
Q: Is it current or superseded?
A: The 2003 edition (Edition 2.0) replaced the earlier 1999 edition; ISO records that ISO/IEC 15433:1999 was superseded by the 2003 edition. Users should check national bodies or the IEC/ISO webstores for any later reconfirmation or withdrawal notices in their country.
Q: Is it part of a series?
A: Yes — it is part of a family of PISN standards (ISO/IEC 11579‑1, 11582, 15428, 15429, 15431, 15432, etc.) that together define reference configurations, supplementary services and inter‑exchange signalling for Private Integrated Services Networks.
Q: What are the key keywords?
A: PISN, PINX, wireless terminal authentication, SS‑WTAT, SS‑WTAN, Q reference point, challenge‑response, signalling protocol, conformance (PICS, ASN.1, SDL).
