7、entification (MCID) supplementary service enables a user to request that the source of an incoming call is identified and registered in the network. Source ITU-T Recommendation Q.951.7 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the

8、5th of June 1997. I FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating a

9、nd tariff questions and issuing Recommendations 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,

10、produce Recommendations on these topics. 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

11、 with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a I telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation

12、 of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Propery Rights, whether asserted by ITU members or others outside of the Recommendation development process. As o

13、f the date of approval of this Recommendation, 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

14、urged to consult the TSB patent database. O ITU 1997 All rights reserved.

22、D) 7.1 Scope This Recommendation specifies the stage 3 of the Malicious Call Identification (MCID) supplementary service for the Integrated Services Digital Network (ISDN) at the T reference point or coincident S and T reference point (as defined in Recommendation 1.41 1 i) by means of the Digital S

23、ubscriber Signalling System No. 1 (DSS 1) protocol. Stage 3 identifies the protocol procedures and switching functions needed to support a telecommunications service (see Recommendation I. 130 In addition, this Recommendation specifies the protocol requirements at the T reference point where the ser

24、vice is provided to the user via a private ISDN. This Recommendation does not specifj the additional protocol requirements where the service is provided to the user via a telecommunications network that is not an ISDN. This supplementary service enables a user to request that the source of an incomi

25、ng call is identified and registered in the network. The MCID supplementary services is applicable to all circuit-switched telecommunication services. This Recommendation is applicable to equipment, supporting the MCID supplementary service, to be attached at either side of a T reference point or co

26、incident S and T reference point when used as an access to the public ISDN. 21). 7.2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

Where reference is made to xxxx“ invoke component, an invoke component is meant with its operation value set to the value of the operati

37、on “xxxx“. 7.3.10 return result component: See 6.314.932 6 for the application of this component as defined in Recommendation X.219 7.

40、s of the Recommendation for each individual supplementary service. NOTE - Other aspects of interactions that do not affect the DSS 1 protocol are covered in the service description for the relevant supplementary services. 7.3.14 not applicable: The interaction between the two identified supplementar

41、y services is outside the scope of this Recommendation, e.g. the interaction is between the supplementary service and itself, and is therefore covered in the Recommendation for the individual supplementary service. 7.4 Abbreviations This Recommendation uses the following abbreviations: ASN. 1 Abstra
