8、ICIOUS CALL IDENTIFICATION (MCID) Summary This Recommendation defines the essential functions, procedures and messages of the ISUP protocol required for the provisioning to ISDN users of the Malicious Call Identification supplementary service, which enables a user to request that the source of an in
9、coming call is identified and registered in the network. Source ITU-T Recommendation 4.73 1.7 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 5th of June 1997. STD-ITU-T RECMN Q.731.7-ENGL 1997 48b259L b38370 224 FOREWORD ITU (Intern
10、ational Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (IT-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommend
11、ations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
12、The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommend
13、ation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use
14、 of a claimed Intellectual Property Right. The IT 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 Recommendati
15、on, the ITU hadhad not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O

The following messages and parameters are used to support the MCID supplementary service. 4 Messages - Identification request. - Identification response. b) Parameters - MCID request indicators. - MCID response indicators. The Identification request and Identification
39、response messages are accompanied by the Message compatibility information parameter. The MCID request and MCID response indicators are accompanied by the Parameter compatibility information parameter. The procedures for compatibility are defined in Recommendation 4.764 121. 7.5 Signalling requireme

41、e with bit A of the MCID request indicator set to 1, the originating local exchange sends an Identification response message with bit A of the MCID response indicator set to 1. The number information of the calling user is included in the Calling party number parameter. When the MCID information is
42、not available, an Identification response message with bit A of the MCID response indicator set to O is returned. The originating local exchange must be able to support the MCID request until the reception of the Answer or Connect message. 7.5.2.1.2 Exceptional procedures When the MCID supplementary
43、 service is not supported, an Identification response message with bit A of the MCID response indicator set to O is returned. 7.5.2.2 Actions at the transit exchange 7.5.2.2.1 Normal operation The transit exchange shall pass a received Identification request message transparently to the preceding ex
44、change. The subsequent Identification response message is passed transparently to the succeeding exchange.
