9、Recommendation A.8 procedure. ii ITU-T Rec. Q.764 (1999)/Amd.5 (09/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T i
10、s responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study b
11、y the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a coll
12、aborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain cert
13、ain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requireme
14、nts. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. I
15、TU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual
16、 property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

19、 of VED information Add the following clause: 2.29 Transport of VED information 2.29.1 Forward direction The VED information parameter for the calling party is generated by the mobile network exchange that controls the VED for the calling mobile subscriber. The VED information parameter for the call
20、ing party is sent in the forward direction in the IAM. All intermediate exchanges shall pass this parameter unchanged to inform the other exchanges that the VED for the calling mobile subscriber is inserted. 2.29.2 Backward direction The VED information parameter for the called party is generated by
21、 the mobile network exchange that controls the VED for the called mobile subscriber. The VED information parameter for the called party is sent in the backward direction in the ANM or CON. All intermediate exchanges shall pass this parameter unchanged to inform the other exchanges that the VED for t
