3、r in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of TINEIA fiom manufacturing or selling products not conforming to such Standards and Publications, nor s
4、hall the existence of such Standards and Publications preclude their voluntary use by those other than TIA/EIA members, whether the standard is to be used either domestically or internationally. Standards, Publications and Bulletins are adopted by TIAEIA in accordance with the American National Stan
5、dards Institute (ANSI) patent policy. By such action, TIALEIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard, Publication or Bulletin. Technical Bulletins are distinguished fiom TIALEIA Standards or Interim Standards, in
6、 that they contain a compilation of engineering data or information useful to the technical community, and represent approaches to good engheering practices that are suggested by the formulating committee. This Bulletin is not intended to preclude or discourage other approaches that similarly repres

TSB74 INTRODUCTION This Telecommunications Systems Bulletin (TSB) applies to TIA/EIA/IS-95-A. It introduces support for the following new capabilities: 14.4 kbps Data Rat
11、e - This provides physical layer, multiplex layer and signaling layer support for a new family of transmission rates, including 14.4 kbps, 7.2 kbps, 3.6 kbps and 1.8 kbps rates. Enhanced Service Negotiation - This provides the means for establishing a common service configuration for use by the mobi
12、le station and base station. The service configuration can include multiple active service options and can makeuse of both primary and secondary traffic. Backward compatibility with service option negotiation, as specified in TIA/EiA/IS-95-A, is maintained. Enhanced Status Messaging - This provides
13、the means for the base station to ascertain the detailed capabilities of the mobile station, such as supported band classes, operating modes, service options, multiplex options, and rate sets. Redirection and Handoff to PCS - This provides the means for redirecting and handing off the mobile station
14、 to a digital wideband spread spectrum system operating within the 1.8 to 2.0 GHz frequency range, as specified by ANSI J-STD-008, and permits the mobile station to select a PCS system during the system selection process. MIN to IMSI Transition Support - This provides an improved means for making th
15、e transition from MIN-based addressing to IMSI-based addressing. This TSB uses the same structure and section numbering as TiA/EiA/IS-95-A. Sections of this TSB that remain unchanged relative to IS-95-A are represented using ellipses contained within brackets (I.). Modifed sections are either reprod
16、uced in their entirety or use the I. notation to represent unchanged portions. Within modified sections, change bars indicate the specific paragraphs, figures, or table cells that have changed. Within modified paragraphs and table cells. strike-throughs indicate deleted text and underlines indicate
