2、IA-637-B-1E-2006 Approved: June 28, 2006 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, and assisting the purchaser in
3、 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 Standards and Publications. Neith
4、er 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 policy. By such action, TIA does
5、 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 is the responsibility of the
6、user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use. (From Standards Proposal No. 3-4391-RV2-AD1E, formulated under the cognizance of the TIA TR-45 Mobile (b) there is no assurance that the Document wi

TIA/EIA-637-B-1 i PREFACE These technical requirements form a standard for a Short Message Service (SMS), providing delivery of text and numeric informati
37、on for paging, messaging, and voice mail notification. This standard includes Service Option 6 and Service Option 14 (as defined in 15), which support delivery of short messages on Traffic Channels. Service Option 6 and Service Option 14 conform to the general requirements for service options specif
38、ied in 10. A mobile station can obtain Short Message Service operating in either the analog or the spread spectrum (CDMA) mode when it conforms to this standard. This standard does not address the quality or reliability of Short Message Service, nor does it cover equipment performance or measurement
39、 procedures. SECTION SUMMARY 1. Introduction. This section defines the terms, references, protocols and network reference model used in this document. 2. SMS Relay Layer. This section defines the requirements for the lower layer of the SMS bearer service protocols. The SMS Relay Layer provides the i
40、nterface between the Transport Layer and the Link Layer used for message transmission. 3. SMS Transport Layer. This section defines the requirements for the upper layer of the SMS bearer service protocols. The SMS Transport Layer manages the end-to-end delivery of messages. 4. SMS Teleservice Layer.
41、 This section defines the requirements for the SMS Teleservice Layer, which provides application-level data formats and procedures. TIA/EIA-637B-1 ii NOTES 1. The following verbal forms are used: “Shall” and “shall not” identify requirements to be followed strictly to conform to the standard and fro
42、m which no deviation is permitted. “Should” and “should not” indicate that one of several possibilities is recommended as particularly suitable, without mentioning or excluding others; that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain
43、 possibility or course of action is discouraged but not prohibited. “May” and “need not” indicate a course of action permissible within the limits of the standard. “Can” and “cannot” are used for statements of possibility and capability, whether material, physical, or causal. 2. Footnotes appear at
44、various points in this specification to elaborate and to further clarify items discussed in the body of the specification. 3. Unless indicated otherwise, this document presents numbers in decimal form. Binary numbers are distinguished in the text by the use of single quotation marks. In some tables,
45、 binary values may appear without single quotation marks if table notation clearly specifies that values are binary. The character x is used to represent a bit of unspecified value. For example xxx00010 represents any 8-bit binary value such that the least significant five bits equal 00010. Hexadeci
46、mal numbers (base 16) are distinguished in the text by use of the form 0xh h where h h represents a string of hexadecimal digits. For example, 0x2fa1 represents a number whose binary value is 0010111110100001 and whose decimal value is 12193. Note that the exact number of bits in the binary represen
47、tation of a hexadecimal number strictly depends upon the implementation requirements for the variable being represented. 4. “Base station” refers to the functions performed on the fixed network, which are typically distributed among a cell, a sector of a cell, and a mobile communications switching c
