1、 TSB-169 April 2012cdma2000 Multimedia Services Evaluation Methodology NOTICE TIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products,

2、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 non-member of TIA from manufacturing or selling products not conforming to such Sta

3、ndards 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 TIA in accordance with the American National Standards Institute (ANSI) patent po

4、licy. 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 safety problems associated with its use or all applicable regulatory requirements. It

5、 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. (From Project No. 3-0241-A, formulated under the cognizance of the TIA TR-45 Mobile (b) there is no assurance that the

6、 Document will be approved by any Committee of TIA or any other body in its present or any other form; (c) the Document may be amended, modified or changed in the standards development or any editing process. The use or practice of contents of this Document may involve the use of intellectual proper

7、ty rights (“IPR”), including pending or issued patents, or copyrights, owned by one or more parties. TIA makes no search or investigation for IPR. When IPR consisting of patents and published pending patent applications are claimed and called to TIAs attention, a statement from the holder thereof is

8、 requested, all in accordance with the Manual. TIA takes no position with reference to, and disclaims any obligation to investigate or inquire into, the scope or validity of any claims of IPR. TIA will neither be a party to discussions of any licensing terms or conditions, which are instead left to

9、the parties involved, nor will TIA opine or judge whether proposed licensing terms or conditions are reasonable or non-discriminatory. TIA does not warrant or represent that procedures or practices suggested or provided in the Manual have been complied with as respects the Document or its contents.

11、of mandatory, alternate or optional elements (as defined in the TIA Engineering Manual, 4thedition) then (i) TIA disclaims any duty or 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 encour

12、agement of voluntary disclosure (see Engineering Manual Section 6.5.1) of Essential Patent(s) and published 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 Esse

32、 2 multimedia services. The simulations are designed to capture performance characteristics of source 3 codecs, including appropriate RTP packetization schemes used for cdma2000 multimedia services. 4 The layers below the RTP layer are abstracted in a software tool with RTP packets as input, RTP 5 p

33、ackets as output and appropriate control/configuration parameters to capture packet loss and delay 6 behavior of a given wireless IP network. Appropriate metrics to capture user experience under packet 7 losses and variable delays are also provided. Common source material is proposed for use in the

34、8 simulations. 9 1.1 Scope 10 The scope of this technical report is to provide common simulation conditions to enable 11 repeatable evaluations of source coding and RTP packetization options. It is possible to perform cross 12 verifications. The document includes 13 Common source material (e.g., vid

35、eo clips) 14 Pointers to multimedia codecs used in cdma2000 multimedia services, including technical 15 descriptions and reference software when available 16 An abstraction of layers below RTP in wireless IP networks 17 Suitable objective metrics 18 1.2 Requirements Language 19 “Shall” and “shall no
