3、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 selling p
4、roducts 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 published at th
5、e 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 Manual, loca
6、ted 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 for rev
7、ision should be directed to: Standards that a certain course of 5 action is preferred but not necessarily required; or that (in the negative form) a certain 6 possibility or course of action is discouraged but not prohibited. “May” and “need not” 7 indicate a course of action permissible within the
8、limits of the standard. “Can” and 8 “cannot” are used for statements of possibility and capability, whether material, 9 physical, or causal. 10 2. Footnotes appear at various points in this specification to elaborate and to further clarify 11 items discussed in the body of the specification. 12 3. U
9、nless indicated otherwise, this document presents numbers in decimal form. 13 Binary numbers are distinguished in the text by the use of single quotation marks. In 14 some tables, binary values may appear without single quotation marks if table notation 15 clearly specifies that values are binary. T
10、he character x is used to represent a bit of 16 unspecified value. For example xxx00010 represents any 8-bit binary value such that 17 the least significant five bits equal 00010. 18 Hexadecimal numbers (base 16) are distinguished in the text by use of the form 0xhh 19 where hh represents a string o
11、f hexadecimal digits. For example, 0x2fa1 represents a 20 number whose binary value is 0010111110100001 and whose decimal value is 12193. 21 Note that the exact number of bits in the binary representation of a hexadecimal number 22 strictly depends upon the implementation requirements for the variab
12、le being 23 represented. 24 4. “Base station” refers to the functions performed on the fixed network, which are 25 typically distributed among a cell, a sector of a cell, and a mobile communications 26 switching center. 27 Copyright Electronic Industries Alliance Provided by IHS under license with E

34、rom one 5 representation to another, often with the goal of saving memory space or transmission bandwidth 6 (compression). 7 continuous media: media with an inherent notion of time. In the present document speech, 8 audio, synthetic audio, and video are examples of continuous media. 9 dynamic media:
35、 same as continuous media 10 discrete media: media that itself does not contain an element of time. In the present document 11 text and still image are examples of discrete media. Note that timed text and bit map graphics can 12 be continuous media also, depending on the presentation aspects. 13 fil
36、e format: an unambiguous method for storing data on a memory device (usually non-volatile). 14 media synchronization and media presentation: description of the spatial layout and temporal 15 behavior of a presentation; it can also contain hyperlinks. 16 multimedia: a combination of multiple media el
37、ements used in a service to enrich the user 17 experience. 18 natural media: media that occur naturally. In the present document, speech, audio, video and 19 still image are examples of natural media. 20 synthetic media: media that are synthesized from algorithms and/or semantic descriptions. In 21
38、the present document, bit map graphics, vector graphics and synthetic audio are examples of 22 synthetic media. 23 user agent: the module on the terminal that performs MMS specific operations on a users 24 behalf. 25 3.2 Abbreviations 26 For the purposes of the present document, the abbreviations gi

43、 or networking permitted without license from IHS-,-,-TIA-1011 64 Media formats 1 Multiple media elements shall be combined into a composite single MM using MIME multipart 2 format as defined in 17. The media type of a single MM element shall be identified by its 3 appropriate MIME type, whereas the
44、 media format shall be indicated by its appropriate MIME 4 subtype. For creating an MM with the media elements described in 22, the MIME subtypes 5 specified in 22 shall be used. 6 In order to guarantee minimum support and compatibility between multimedia messaging 7 capable terminals, an MMS User A
45、gent supporting specific media types shall comply with the 8 following selection of media formats. Unrecognized subtypes of MIME types image, video, 9 audio and application shall be treated as “application/octet-stream”; that is, the MMS User Agent 10 shall treat unrecognized subtypes as attachments
46、. 11 4.1 Text 12 The MMS User Agent shall support the media type “text” as follows: 13 Shall use any character encoding (charset) that contains a subset of the logical characters in 14 Unicode 2(e.g. US-ASCII 3, ISO-8859-1 4, UTF-8 5, GSM 7-bit default alphabet 6, 15 Shift_JIS, etc.). 16 Shall treat
47、 any unrecognized subtypes of “text“ as subtype “plain“ as long as the MMS 17 Terminal MIME implementation knows how to handle the charset. 18 Shall treat any other unrecognized subtypes of “text” and unrecognized charsets as 19 “application/octet-stream“. 20 An MMS User Agent should support “text/p
48、lain; format=flowed“, as specified in 25. 21 4.2 Speech 22 The MMS terminal shall support the media type “speech”. The MMS terminal shall support one 23 or both of the following speech codecs: 24 3GPP2 13K 23; 25 AMR 21. 26 Appropriate speech transcoding (i.e., of 13K to AMR or vice versa) should be
49、 applied by the 27 system operator to allow for successful decoding of MMS content on terminals that support only 28 one of the above speech codecs. 29 Transcoding of messages in the network prior to delivery is described in 29, Section 7.1.3, 30 “Retrieval of a Multimedia Message in the recipient MMSE”. 31 Copyright E
