1、 TIA-102.BAJC-A (Revision of TIA-102.BAJC) April 2015Project 25 Tier 2 Location Services Specification ANSI/TIA-102.BAJC-A-2015 APPROVED: MARCH 27, 2015 NOTICE TIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufactu
2、rers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Standards and Publications shall not in any respect preclude any member or n
3、on-member of TIA from manufacturing or selling products not conforming to such Standards and Publications. Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or internationally. Standards and Publications are adopted by
4、 TIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. This Standard does not purport to address all saf
5、ety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

The use or practice of contents of this Document may involve the use of intellectual property rights (“IPR”), including pending or issued patents, or copyrights, owned by one or more parties. TIA makes no search or investigation for IPR.
12、 When IPR consisting of patents and published pending patent applications are claimed and called to TIAs attention, a statement from the holder thereof is requested, all in accordance with the Manual. TIA takes no position with reference to, and disclaims any obligation to investigate or inquire int
13、o, the scope or validity of any claims of IPR.

16、 obligation to search or investigate the records of any other SSO for IPR or letters of assurance relating to any such Normative Reference; (ii) TIAs policy of encouragement of voluntary disclosure (see TIA Procedures for American National Standards Annex C.1.2.3) of Essential Patent(s) and publishe
17、d pending patent applications shall apply; and (iii) Information as to claims of IPR in the records or publications of the other SSO shall not constitute identification to TIA of a claim of Essential Patent(s) or published pending patent applications.

23、H LIMITATIONS. TIA-102.BAJC-A i Foreword (This foreword is not part of this document.) This document has been created in response to a request by the APCO/NASTD/FED1Project 25 Steering Committee as provided for in a Memorandum of Understanding (MOU) dated April 1992 and amended December 1993. The MO
24、U states APCO/NASTD/FED shall devise a Common System Standard for digital public safety communications (the Standard) commonly referred to as Project 25 or P25, and that TIA, as agreed to by the membership of the appropriate TIA Engineering Committee, will provide technical assistance in the develop
25、ment of documentation for the Standard. If the abbreviation “P25” or the wording “Project 25” appears on the cover sheet of this document when published that indicates the APCO/NASTD/FED Project 25 Steering Committee has adopted this document as part of the Standard. The appearance of the abbreviati
26、on “P25” or the wording “Project 25” on the cover sheet of this document or in the title of any document referenced herein should not be interpreted as limiting the applicability of the information contained in any document to “P25” or “Project 25” implementations exclusively. This document provides
27、 a specification of the Tier 2 Location Services for TIA-102 Data Services. This document was developed by the TIA TR-8.5 Signaling and Data Transmission Subcommittee based on materials originated by the APCO Project 25 Interface Committee (APIC) Data Task Group (DTG). The 2ndedition (Revision A) of
28、 this document defines messages and procedures for Tier 2 Location Services based on material originally published in TIA-102.BAJC. This revision adds procedures that allow a Location Service Host System (LSHS) to detect when a Location Service Client is activated by a Subscriber Unit (SU), verify t
29、hat the SU is authorized to use the service, and learn the network address of the SU. This revision also addresses several errata comments. This document cancels and replaces TIA-102.BAJC. There is one annex in this document for conformance requirements. Annex A is normative as is considered part of
30、 this specification. TIA does not evaluate, test, verify or investigate the information, accuracy, soundness, or credibility of the contents of the Document. In Publishing the Document, TIA disclaims any undertaking to perform any duty owed to or for anyone. Some aspects of the specifications contai
31、ned in this document may not have been fully operationally tested; however, a great deal of time and good faith effort has been invested in the preparation of this document to ensure the accuracy of the information it contains. 1APCO/NASTD/FED is an abbreviation for the Association of Public-Safety
32、Communications Officials (APCO), the National Association of State Technology Directors (NASTD), and the various agencies of the Federal government (FED). TIA-102.BAJC-A ii Patent Identification The readers attention is called to the possibility that compliance with this document may require the use
33、 of one or more inventions covered by patent rights. By publication of this document, no position is taken with respect to the validity of those claims or any patent rights in connection therewith. The patent holders so far identified have, we believe, filed statements of willingness to grant licens
34、es under those rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such licenses. The following patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: No patents have been identified TIA shall not b
35、e responsible for identifying patents for which licenses may be required by this document or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention.
