10、tember 1997. 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 and tari
11、ff 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, produce
12、 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 with I

14、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 Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the da
15、te of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

25、221 INTRODUCTION TO INTELLIGENT NETWORK CAPABILITY SET 2 (Geneva, I99 7) 1 Introduction Intelligent Network Capability Set 2 (IN CS-2) is the second standardized stage of the Intelligent Network (IN) as an architectural concept for the creation and provision of services, including telecommunication
26、services, service management services and service creation services. This Recommendation gives an introduction to IN CS-2. It describes the main characteristics and overall capabilities of IN CS-2 and defines the service aspects, network aspects and functional relationships that form the basis of th

32、phased approach of IN capability sets has been described in Recommendation Q.1201. In order to prepare for the next phases of IN (CS-3 and beyond), the IN CS-2 Recommendations contain both complete technical specifications (with complete support for physical architecture and detailed protocol descri
33、ption) and incomplete specifications that are intended to be the base for subsequent capability sets (with SIB description and the impact on the functional architecture). Capabilities which are only incompletely covered by IN CS-2 Recommendations are highlighted through special notes or caveats. 3 G
34、eneral description and scope of IN CS-2 3.1 Criteria for IN CS-2 IN CS-2 defines an initial subset of IN capabilities that meet the following general criteria: a b) cl d) IN CS-2 is a subset of the target Intelligent Network architecture; IN CS-2 is a superset of IN CS-I, as defined in the IN CS-1 R
35、ecommendations (1995); IN CS-2 is a set of definitions of capabilities that is of direct use to both manufacturers and network operators; IN CS-2 provides network capabilities defined to support the set of IN CS-2 benchmark services or service features. These capabilities can also be used for the su
36、pport of other services that may, or may not, be standardized by ITU-T. The IN CS-2 architecture could be applied for PSTN, ISDN, and mobile networks. 3.2 Evolution of IN CS-2 The IN CS-2 Recommendations (Q. 122x-Series) form a detailed and stable basis for implementing IN CS-2 telecommunication ser
37、vices. They also give high-level guidelines for supporting service management services and service creation services and some partially supported telecommunication services. Complete technical specifications of these services will be in the subsequent IN capability sets. As IN CS-1, IN CS-2 takes in
38、to account the evolution requirement. It is defined to support the IN CS-2 benchmark services and service features without assumptions that are known to limit its evolution into future capability sets. 2 Recommendation Q.1221 (09/97) The IN CS-2 Recommendations are intended to give the same degree o

42、e features that are to be supported by IN CS-2 are fundamental to the IN CS-2 Service-Independent Building Blocks (SIBS), call processing model and service control principles. Three types of services have been identified in IN CS-2: telecommunication service, service management service and service c
43、reation services. The last two types of services are first introduced in IN CS-2. Tables 2 and 3 list IN CS-2 benchmark services and service features, which, in addition to IN CS-I related telecommunication services/service features, can be used to identify and verify the service-independent capabil
44、ities of IN CS-2. Appendix I provides short prose descriptions of the benchmark services and service features. It was used to develop the current Q.122-Series of Recommendations and was intended for this purpose only. It is not to be used by service designers for service creation. Recommendation Q.1
45、221 (09/97) 3 STD-ITU-T RECMN Q.122L-ENGL 1997 m 48b257L Ob443b7 T53 NOTE 1 - The above service names apply to the descriptions of targeted services (see Appendix I), and 1 not to the user-network interface descriptions provided by ITU-T Study Group 1. NOTE 2 - Network implementation aspects may be
46、important for some services. a) These services may be partially supported in IN CS-2. For example, they may be supported at the GFP level but not supported at the protocol level. Some of these services may also require capabilities beyond IN CS-2. Please note that SIBS are used for modelling purpose
47、. They are not meant to be used as a standardized solution for service creation, even though some organizations may wish to use them for this purpose.
