TIA TSB-29-F

When the first edition of the Mobile Station – Land Station Compatibility Specification (IS-3, now TIA/EIA-553-A) was issued, it was envisioned that it would be adopted for use within North America. Provisions were included for international implementation; however, detailed guidelines to assist with such implementations were not included. TIA Subcommittee TR-45.2 (now TIA TR-45.8) recognized the need to provide such guidance and chartered a Working Group (Working Group VI, since dissolved) with this responsibility. The result of this Working Group's deliberations has been the production of TSB-29 as well as the internationalization of other TIA standards, such as, TIA/EIA- 41-D (N.S0005), TIA-751 (N.S0009), TIA/EIA/IS-807 (N.S0016), TIA/EIA/IS-875 (N.S0027), TIA/EIA-124 (X.S0014), TIA/EIA-136, IS-95, IS-91, and TIA/EIA-2000 (C.S0001~6). TSG-SX (formerly TSG-X and TSG-N) has taken TSB-29 and produced the specification X.R0070, formerly N.S0017.

The principle aspects of international implementation addressed by this document are:

• The administration and assignment of Mobile Identification Numbers (MINs)
• Format of International Mobile Subscriber Identities (IMSIs)
• The administration and assignment of System Identification Numbers (SIDs)

The goal of this publication is to provide the international wireless telecommunications industry with the framework permitting the coordinated implementation of Wireless Radio Telecommunication Systems in compliance with the provisions of the AMPS family of air interface standards (e.g., TIA/EIA-553, IS-54, IS-91, IS-95, TIA/EIA-2000, and TIA/EIA-136).
