6、commendations defines the Intelligent Network (IN) Application Protocol (INAP) for IN Capability Set 3 (IN CS-3), the INAP for IN CS-3 based upon IN CS-2 4.1228 and 4.1224 specification (1997) and the general rules for INM provided in 4.1208, and is consistent with the scope of IN CS-3 as defined in
7、 IT-T Q. 123 1. Within the Q.123 series of Recommendations, the Q.1238.x series describes the protocol realizing the Q. 123 1 Distributed Functional Plane in a service and vendor implementation independent manner, as constrained by the capabilities of the embedded base of network technology. This pr
8、ovides the flexibility to allocate distributed functionality into multiple physical network configurations and to evolve IN from IN CS-3 to some future IN CS-N. This Recommendation belongs to Q.1238.x series of ITU-T Recommendations for IN Capability Set 3. It covers the CUSF-SCF interface including
9、 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 clause 13 ASN. 1 definitions. Source ITU-T Recommendation 4.1238.7 was prepared by TTU-T Study Group 11 (1997-2000) and appro

11、Telecommunication Union (IT) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of IT. -T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them
12、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 turn, produce Recommendations on these topics. The approval of ITU-T
13、 Recommendations is covered by the procedure laid down in WTSC Resolution 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 EC.

35、ity set 3: SCF-CUSF interface 1 Scope This Recommendation belongs to the Q.1238.x series of IT-T Recommendations for IN Capability Set 3. It specifies the protocol on the CUSF-SCF interface and provides a description of the aspects of the CUSF and SCF Functional Entities which are involved in the re
36、alization of this interface. 2 References All ITU-T Recommendations and other references are identified in ITU-T Q. 1238.1. 3 Abbreviations and acronyms All abbreviations and acronyms used in this text are defined in IT-T 4.1238.1. 4 Relationships 4.1 SCF-CCF/CUSF relationship The SCF-CUSF relations
37、hip is used for messages between an SCF and a CUSF in the public network. This relationship provides service or service features which need call-unrelated user interaction. This provides, for example, user location registration, user authentication, supplementary service activation or de-activation.
38、 Details of service drivers can be found in ITU-T Q. 123 1. This relationship is used for three cases, and respective cases are exclusive for the others. Case 1) For sendingheceiving ROSE APDUs to/from a user. Case 2) For sendingkeceiving US1 information to/from a user. Case 3) For relaying some inf
39、ormations for call unrelated association establishment fiom 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 relationship is not defined in IN CS-3, and is not mandatory. This relationship may be
40、 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 CCFKUSF model shown in Figure 1 is for a single-ended service logic instance related to a user. The purpose of this model
41、 is to provide a framework for the understanding of call unrelated modelling with respect to the CCFKUSF. 1 This Recommendation includes an electronic attachment containing clause 13 ASN. 1 defnitions. ITU-T 4.1238.7 (06/2000) 1 5.2 CCFICUSF components The CCF/CUSF model consists of several entities
42、. 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 (BNCM) This entity provides an abstraction of an association and proceedings for call unre
43、lated 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 instances. It also manages resources required to support basic call unrelated control. The
44、 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 This entity interacts with the SCF via SCF Access Manager in the course of providing IN services/features to users. It provides the SCF with an observabl
45、e 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 also detects non-call processing events that should be reported to active IN service logic instances or can lead to the invocati
46、on of IN service logic instances. It manages CUSF resources required to support IN service logic instances, if any. 5.2.3 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 arbitr
47、ate IN/non-IN call associatedkall unrelated associated services/features and IN call unrelated associated services/features 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 an
48、d IN-NSM to provide the CUSF with a unified view of call unrelated processing internal to the CUSF for an association. IN - Non-Switching Manager (IN-NSM) Feature Interaction Managermon-Call Manager (FIM/NCM) 5.3 Relationship of CCFKUSF model components 5.3.1 BNCM relationship to IN-NSM This is the
49、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 identi how basic call unrelated processing and IN call unrelated processing interact. 5.3.2 This is the relationship that encompasses the interaction between the BNCM and the FIM/NCM, and the interaction between the IN-NSM and the FIM/NCM. The messages related to these interactions are not externally visible and are n
