1、 TIA DOCUMENT Position Determination Service for cdma2000 Spread Spectrum Systems TIA-801-A (Revision of TIA/EIA/IS-801) APRIL 2004 TELECOMMUNICATIONS INDUSTRY ASSOCIATION The Telecommunications Industry Association represents the communications sector of Copyright Telecommunications Industry Associ
2、ation Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-NOTICE TIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facil
3、itating 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 Publications shall not in any respect preclude any member or non-member of TIA from manufacturing or s
4、elling products not conforming to such Publications. Neither shall the existence of such Documents preclude their voluntary use by non-TIA members, either domestically or internationally. TIA DOCUMENTS TIA Documents contain information deemed to be of technical value to the industry, and are publish
5、ed at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of a American National Standard (ANS). Further details of the development process are available in the TIA Engineering Manu
6、al, located at http:/www.tiaonline.org/standards/sfg/engineering_manual.cfm TIA Documents shall be reviewed on a five year cycle by the formulating Committee and a decision made on whether to reaffirm, revise, withdraw, or proceed to develop an American National Standard on this subject. Suggestions
7、 for revision should be directed to: Standards that a certain course of action is preferred, but not necessarily required; or (in 5 negative form) that a certain possibility or course of action is discouraged, but not prohibited. “May” 6 and “may not” indicate a course of action permissible within t
8、he limits of this standard. “Can” and 7 “cannot” are used for statements of possibility and capability, whether material, physical or causal. 8 2. This standard is applicable to systems defined in 189101112 and 14. 9 3. The terms “location” and “position” are used interchangeably throughout this doc
9、ument. In this 10 respect the definition of the term differs from the historic use of location in wireless systems to 11 identify the mobiles current serving system. 12 4. Those wishing to deploy systems in the United States should also take notice of the requirement to be 13 compliant with Federal
10、Communications Commission (FCC) Rulings on 911 Emergency Services. 14 5. “Base station” refers to the functions performed on the land side, which are typically distributed 15 among a Base Station Transceiver (BTS), a Base Station Controller (BSC), a Mobile Switching 16 Center (MSC), Mobile Positioni
11、ng Center (MPC), Position Determination Entity (PDE) and any Inter-17 Working Function (IWF) required for network connection. These elements are grouped together, 18 because there is no need to distinguish them in an air interface standard. See TSB-100 Wireless 19 Reference Model and Enhanced Wirele
12、ss 9-1-1 Phase 2. 20 6. Footnotes appear at various points in this specification to elaborate and to further clarify items 21 discussed in the body of the specification. 22 7. This document specifies message identifiers for more than one PDDM type. Wherever a message has 23 been re-used without enha
13、ncement or modification in a subsequent PDDM type, the original name 24 was used, but with an additional version tag in the form of “vn”, where n represents the nthversion of 25 the message. The message formats are identical for all versions of the same message; the version 26 numbers are used solel
14、y to distinguish the associated PDDM types. 27 8. Unless indicated otherwise, this document presents numbers in decimal form. Binary numbers are 28 distinguished in the text by the use of single quotation marks. 29 9. The following operators define mathematical operations: 30 indicates multiplicatio
15、n. 31 x indicates the smallest integer greater or equal to x: 1.1 = 2, 2.0 = 2. 32 x indicates the largest integer less than or equal to x: 1.1 = 1, 1.0 = 1. 33 | x | indicates the absolute value of x: | -17 |= 17, | 17 |=17. 34 indicates exclusive OR (modulo-2 addition). 35 min (x, y) indicates the
16、 minimum of x and y. 36 max (x, y) indicates the maximum of x and y. 37 x mod y indicates the remainder after dividing x by y: x mod y = x - (y x/y). 38 8. Wherever this document refers to CDMA System time in frames, it is taken to mean an integer value t such 39 that: t = s/0.02,where s represents
