25、of CS-1 and by describing its main characteristics and overall capabilities. It further defines the service aspects, network aspects, and functional relationships that form the basis of the CS-1 capabilities. Q.1213: Global Functional Plane for Intelligent Network CS-1 This Recommendation provides t
26、he functional characteristics of the Global Functional Plane associated specifically with IN CS-1. The following functional characteristics are specific to IN CS-1 and are addressed in this Recommendation: - - CS-1 Service Independent Building Blocks (SIBs). The Basic Call Process SIB. - - The relat
27、ionships between the Service Plane and the GFP. Stage 1 SDL diagrams are provided for the CS-1 SIBs where needed to clarify SIB operation. Q.1214: Distributed Functional Plane for Intelligent Network CS-1 This Recommendation provides the following: - - - - The IN Distributed Functional Plane archite
28、cture for IN CS-1, in terms of a subset of the general IN DFP. Static and Dynamic models of the functional entities related to IN service execution. SIB Stage 2 descriptions to identify information flows and functional entity actions for IN CS-1. Detailed information flow descriptions, including inf
29、ormation elements and functional descriptions, as the basis for specifying IN protocols. - A starting point for the study of call party handling capabilities beyond the two-party call setup and clearing. Within the Q. 1210-Series Recommendations, Q. 1214 describes the distribution of GFP functionali
30、ty defined in Recom- mendation 4.1213 in a service and vendorrimpiementation independent manner, as constrained by the capabilities of the embedded base of evolvable network technology. This provides the flexibility to allocate distributed functionality into multiple physical network configurations,
31、 as described in Recommendation Q.1215, and to evolve IN from CS-1 to some future CS-N. It also provides a framework from which IN protocols are specified for CS-I. as described in Recommendation 4.1218. 2 Recommendation Q.1219 (W94) ITU-T RECMN*d.L2L9 74 W 4862573 0592734 125 = 4.1215: Physical Pla
32、ne for Intelligent Network CS-1 This Recommendation describes the physical plane of the IN architecture for CS-I. The physical plane of the IN CS-1 identifies the different physical entities and the interfaces between these entities. Q.1218: Intelligent Network Interface Recommendations This Recomme
33、ndation defines the Intelligent Network Application Protocol (INAP) for the support of the capabilities required by the CS-1 target services over the CS-1 interfaces (SSF-SCF, SCF-SDF, and SCF-SRF) as defined in Recommendation Q. 121 1. It defines some of the possible protocol stack scenarios, the o
34、perations which now between the entities and the procedures to be followed at each functional entity. Q.1219: Intelligent Network Users Guide for Capability Set 1 This Recommendation is intended to provide a detailed implementors guide for the IN capabilities provided in IN CS- 1. It includes exampl
35、e service scenarios, as well as details to ensure an understanding and implementation of IN CS- 1. Q.1290: Vocabulary of Terms Used in the Definition of Intelligent Networks This Recommendation provides a vocabulary of terms and definitions which have been studied for application in the documentatio
36、n of Intelligent Networks. 1.4 Initial set of capabilities (Reference, 4.121 1, Introduction to Intelligent Network Capability Set 1 .) CS-1 is the definition and selection of an initial subset of IN capabilities that meet the following general criteria: a) CS-1 is a subset of the target IN architec
37、ture, i.e. the Target Architecture is the Long Term View of the evolvable architecture that will provide the vendor, service, and network independence specifies in 4.1201. b) CS-1 is a set of definitions of capabilities that are of direct use to both manufacturers and network operators (as used in R
38、ecommendation Q.1201) and Service Providers and Equipment Vendors (as used in Recommendation Q. 121 1), i.e. interface recommendations are provided for the manufacturers, equipment vendors, and network providers, and Service definitions are provided for the Serve Providers. CS-1 provides network cap
39、abilities to support services either defined, or in the process of being defined, by CCITT, or by other organizations, (e.g. Universal Personal Telecommunications Service, Freephone, and Virtual Private Network services like Private Numbering Plan), Le. the CS-1 network capabilities were not strictl
40、y driven by CCITT Stage 1 service descriptions such as UFT, Freephone, and PNP, but were provided to incorporate the capabilities needed to support services being defined on an ad hoc basis, thus meeting the guidelines set out in Recommendation 1.312lQ.1201 for providing Service Independence. c) d)
41、CS-1 is the first standardized stage of evolution based upon the existing technology base and on evolvability requirements to ensure that the existing technology base will be re-usable in an IN structured environment, i.e. the Basic Call State Model description reflects the current view of switching
42、 systems existing in physical switching systems, the Service Control Function and Specialized Resource Function are modelled after existing installed systems, and the protocols specified include those already available for implementation. The CS-1 architecture may be supported by, but is not limited
43、 to the Public Switched Telephone Network (PSTN), the Integrated Switched Digital Network (ISDN), and mobile networks. For IN CS-1, the initial subset of IN capabilities focuses primarily on normal call processing scenarios. The Recommendations for IN CS-1 do not completely model or describe failure
44、 scenarios or error handling procedures. However, general information on the error handling semantics can be found in 4.2.2.5lQ.1214, which identifies error cases and SSFlCCF application processing procedures associated with DP processing and response processing from the SCF; Annex B/Q.1214, which i
45、dentifies SSF/CCF - SCF information flow scenarios for error cases; 3/Q.1218, which defines general INAP procedures for error handling such as timer expiry for the SSF, SCF, SRF, and SDF Recommendation Q.1219 (04/94) 3 ITU-T RECMN*Q.LZLS 94 4862591 0592735 Ob1 protocol state machines (3.1.1.5,3.1.2.
46、5,3.1.3.4, and 3.1.4.4, respectively); and clause UQ.1218, which specifies several error types for the INAP for IN CS-I. Also, A.2.7 (Time Handling Aspects) presents service examples with failures. Refer to 12.4.3Q.1400 and in 2.4/Q.775 and 3.2.1.4/Q.775 for general guidelines on error handling proc
47、edures. 1.5 State of Maturity of the CS-1 Recommendations CS-1 is the first Recommendation set providing a framework which will help the various Administrations to develop or customize services independently of any specific manufacturers Intelligent Network elements. Service constructs are also desi
48、gned to be independent of the physical implementation. It is important to recognize that Intelligent Network studies address several complex areas, and where unanimous agreements could not be reached at this time, due to lack of complete understanding of the involved complexities, material was moved
49、 to appendices and annexes. CS-1 must be recognized as not being specified in 100% detail, but is conceptually complete. In some cases there may be insufficient detail to allow different manufacturers to truly build 100% compliant IN capabilities. CS-1 does not address the Operational aspects of an IN network, Service Creation, or the administrative tools (Le. SMS), needed to run it. However, CS-1 does provide a framework that will help Administrations to develop or customize services independently of the manufacturer, within reasonable limits. As such, CS-1 can now be rele
