12、 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. 8 2 NORMATIVECHANGES 9 4
13、.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 During FR SVC establish
14、ment, 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, and they shall be in the
15、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 T1.617. The SETUP message
16、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 includes one or more INTEFSA
17、CE-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 the SETUP and RELEASE COM
18、PLETE 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 Mobility Function 34 1 TIA/E
