2、 for ResaleNo reproduction or networking permitted without license from IHS-,-,-NOTICE TiA/EiA Enginering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufhcturers and purchasers, facilitating interchangeability and improvement o

3、f products, and assisting &e purchaser in selecting and obtaining with minimum delay the proper product for his particular need. J35stence of such Standards and Publications shali not in any respect preclude any member or nonmember of TIA/EIA from manufacftinng or selling products not conforming to

4、such Standards and hblications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TiAEIA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by TIA/EIA in accordance with

5、the American National Standards Iostitute (ANSI) patent policy. By such action, TLAfELA does not assume any liabiiity to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. “WEIA Interim Standards contain information deemed to be of technical

6、 value to the industry, and *e published at the request of the originating Committee without riecessanl * y following the rigorous public review and resolution of comments which is a procedural part of the development of a -IA Standard. TIA/EIA Interim Standards should be reviewed on an annual basis

7、 by the formulating Committee and a decGion made on whether to proceed to develop a TIA/EIA Standard on this subject. TUVEIA Interim Standards must be cancelled by the Committee and removed from the TLA/ELA Standards Catalog before the end of their third year of existence. Publication of tfiis TIA/E

8、IA Interim Standard for trist use and comment has been approved by the Telecommunications Industry Associition. Distribution of this TLA/EIA Interim Standard for comment shaii not continue beyond 36 months from the date of publication. It is expected that foliowing this 36 month period, this TIA/EIA

13、ity to perform interface status exchange at times other than call setup. It is intended that section 4.2.6 in this addendum replace section 4.2.6 in TIA/EIA/IS-658. Also, in section 4.2.9 in this addendum, a new reason code, 0x02, is added to the values The remainder of TIA/EIA/IS-658 is unchanged.

14、8 2 NORMATIVECHANGES 9 4.2.6 Optional Interface Status Exchange 10 11 12 Either the BS/MSC or the IWF may initiate an exchange of interface status information during FR SVC establishment (see 4.2.1 or 4.2.3) or at any other time. This involves an exchange of one or more INTERFACE-STATUS segments. 13

15、 During FR SVC establishment, if the receiving entity responds to a SETUP message with a 14 message including the user-user information element with one or more 15 INTERFACE-STATUS segments, these segments shall refer to the same interfaces as the 16 INTERFACE-STATUS segments in the SETUP message, a

16、nd they shall be in the same 17 order as the INTERFACE-STATUS segments in the SETUP message. I8 19 20 21 22 23 24 25 26 27 28 Either the BS/MSC or IWF may initiate an exchange of interface status information at any time other than FR SVC establishment by sending a SETUP message in accordance with T1

17、.617. The SETUP message shall include a REASON segment with the REASON-CODE field set to 0x02 and one or more INTERFACE-STATUS segments. The receiving entity should respond to the SETUP message with a RELEASE COMPLETE message that includes a REASON segment with REASON-CODE field set to Ox02 and incl

18、udes one or more INTEFSACE-STATUS segments. These INTERFACE-STATUS segments shall refer to the same interfaces as the INTERFACE-STATUS segments in the SETUP message, and they shall be in the same order as the INTERFACE-STATUS segments in the SETUP message. The Call Reference information element in t

19、he SETUP and RELEASE COMPLETE messages shall be sent with a global call reference value. 29 This standard does not address the use of the information contained in the 30 INTERFACE-STATUS segments by either the BS/MSC or the IWF. 31 4.2.7 Initialization 32 . 33 4.2.8 Optional Packet Data Service Mobi
