6、ty set 4: SCF-CUSF Interface Summary The Q.1248.x family of Recommendations defines the Intelligent Network (IN) Application Protocol (INAP) for IN capability set 4 (IN CS-4). This family of Recommendation defines the INAP for IN CS-4 based upon IN CS-3 ITU-T Q.1238 (2000), and the general rules for
7、 INAP provided in ITU-T Q.1208, and is consistent with the scope of IN CS-4 as defined in ITU-T Q.1241. Within the Q.124x series of Recommendations, the ITU-T Q.1248.x family describes the protocol realizing the Q.1244 Distributed Functional Plane in a service and vendor implementation independent m
8、anner, as constrained by the capabilities of the embedded base of network technology. This provides the flexibility to allocate distributed functionality into multiple physical network configurations and to evolve IN from IN CS-4 to some future IN CS-N. This Recommendation belongs to ITU-T Q.1248.x
9、family of Recommendation for IN capability set 4. It covers the CUSF-SCF interface including the description of the aspects of the CUSF and SCF Functional Entities which are relevant to this interface. This Recommendation includes an electronic attachment containing Annex A, ASN.1 definitions. Sourc

11、 Unrelated Service Function (CUSF). ii ITU-T Rec. Q.1248.7 (07/2001) 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 is re
12、sponsible 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 by th
13、e 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 collabor
14、ative 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. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implement
15、ation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU 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
16、 of the date of approval of this Recommendation, ITU had 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

35、U-T Recommendation Q.1248.7 Interface Recommendation for Intelligent Network capability set 4: SCF-CUSF Interface11 Scope This Recommendation belongs to the Q.1248.x family of Recommendations for IN capability set 4. It specifies the protocol on the CUSF-SCF interface and provides a description of t
36、he aspects of the CUSF and SCF Functional Entities which are involved in the realization of this interface. 2 References All ITU-T Recommendations and other references are identified in ITU-T Q.1248.1. 3 Abbreviations and acronyms All abbreviations and acronyms used in this text are defined in ITU-T
37、 Q.1248.1. 4 Relationships 4.1 SCF-CCF/CUSF relationship The SCF-CUSF relationship is used for messages between an SCF and a CUSF in the public network. This relationship provides a service, or service features, which need call-unrelated user interaction. This provides, for example, user location re
38、gistration, user authentication, supplementary service activation or de-activation. Details of service drivers can be found in ITU-T Q.1241. This relationship is used for three cases, and respective cases are exclusive for the others. Case 1) for sending/receiving ROSE APDUs to/from a user. Case 2)
39、for sending/receiving USI informations to/from a user. Case 3) for relaying some informations for call unrelated association establishment from a supplementary service (e.g. CCBS) in CCF (BCUSM). 4.2 CUSF-SSF relationship It is considered that the CUSF and the SSF may have a relationship, but the re
40、lationship is not defined in IN CS-4, and is not mandatory. This relationship may be used to influence the basic call processing in the SSF/CCF (e.g. activation or de-activation of Call Forwarding) via call-unrelated interaction. 5 CCF/CUSF model 5.1 General The CCF/CUSF model shown in Figure 1 is f
41、or a single-ended service logic instance related to a user. The purpose of this model is to provide a framework for the understanding of call unrelated modelling with respect to the CCF/CUSF. _ 1This Recommendation includes an electronic attachment containing Annex A, ASN.1 definitions. ITU-T Rec. Q
42、.1248.7 (07/2001) 2 5.2 CCF/CUSF components The CCF/CUSF model consists of several entities. Each of the entities is briefly described below. It is noted that this shows a conceptual model of CCF/CUSF and is not intended to imply an actual implementation of the CCF/CUSF. 5.2.1 Basic Non-Call Manager
43、 (BNCM) This entity provides an abstraction of an association and proceedings for call unrelated interactions between a user and a network. It detects basic call unrelated events that can lead to the invocation of IN service logic instances or those that should be reported to active IN service logic
44、 instances. It also manages resources required to support basic call unrelated control. The BNCM interacts with the FIM/NCM as described in the FIM/NCM description below. The BNCM also manages the BCUSM and the DP processing logic. 5.2.2 IN Non-Switching Manager (IN-NSM) This entity interacts with t
45、he SCF via SCF Access Manager in the course of providing IN services/features to users. It provides the SCF with an observable view of a CUSF call unrelated processing activities, and provides the SCF with access to CUSF capabilities, such as managing of an association and invoked operations. It als
46、o detects non-call processing events that should be reported to active IN service logic instances or can lead to the invocation of IN service logic instances. It manages CUSF resources required to support IN service logic instances, if any. 5.2.3 Feature Interaction Manager/Non-Call Manager (FIM/NCM
47、) This entity provides mechanisms to prevent invocation of multiple instances of IN and non-IN service logic instances on a single association. The ability of the FIM/NCM to arbitrate IN/non-IN call associated/call unrelated associated services/features and IN call unrelated associated services/feat
48、ures is outside the scope of this capability set. These two types of arbitration need an implicit relationship. The FIM/NCM integrates these interactions mechanisms with the BNCM and IN-NSM to provide the CUSF with a unified view of call unrelated processing internal to the CUSF for an association.
49、5.3 Relationship of CCF/CUSF model components 5.3.1 BNCM relationship to IN-NSM This is the relationship that encompasses the interaction between the BNCM and the IN-NSM, through the FIM/NCM. The message related to this interaction is not externally visible and is not for standardization. However, an understanding of this subject is required to identify how basic call unrelated processing and IN call unrelated processing interact. 5.3.2 BNCM and IN-NSM relationship to FIM/NCM This is the relationship that encompasses the interaction between the BN
