The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studyi

11、ng technical, operating and 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 Grou

12、ps which, in their turn, 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

13、 on a collaborative basis with IS0 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 The ITU draws attention to the possibility that the pra

31、 98 Recommendation Q.1223 GLOBAL FUNCTIONAL PLANE FOR INTELLIGENT NETWORK capability set 2 (Geneva, 799 7) I Gen era I The concepts for the Intelligent Network (IN) are embodied in the Intelligent Network Conceptual Model (INCM) as described in associated Recommendation 1.31 2/Q.1201 I. The Global F

32、unctional Plane (GFP) of the INCM is described in associated Recommendation 1.329/Q.1203 2. IN Capability Set 2 (IN CS-2) is the second standardized stage of the intelligent network as an architectural concept for the creation and provision of telecommunication services. This Recommendation provides

33、 the functional characteristics of the GFP associated specifically with IN CS-2. General GFP aspects are addressed in associated Recommendations 1.312/Q.1201 I and 1.3291Q.1203 2. The concept of domains is introduced within this Recommendation. This concept is used to the purpose of modelling parall

34、el processes. 2 The aim of the Global Functional Plane (GFP) is to satisfy the following objectives: Scope of IN global functional plane for capability set 2 to identify the set of basic network capabilities in terms of service independent to develop modelling techniques to combine these SIBs to mod

35、el the building blocks (SIBs) (see clause 5); services/service features identified on the service plane, .e. parallel processing techniques, granularity levels (see clause 4); service plane, to the set of SIBs on the global functional plane (see clause 8); to facilitate the mapping of SIBS onto the

36、Distributed Functional Plane (DFP) to help identify a comprehensive set of Functional Entity Actions (FEAS) and Information Flows (IFS). SDL diagrams are provided for the individual SIB to help clarify to understand its functionality; only normal SIB execution is considered within the IN CS-2 GFP mo

37、delling, error recovery and error handling mechanisms are out of the scope of the IN a to facilitate the mapping of the service and service features, identified on the CS-2 GFP. 3 References The following ITU-T Recommendations and other references contain provisions which, through reference in this

42、ling for capability set 2 The INCM I models the GFP as shown in service implementation mapping in Figure I. The aim of the global functional plane (GFP) is to satisfy the following two objectives: to identify the set of basic network capabilities in terms of Service Independent Building Blocks (SIBs

43、); to describe how to combine these SIBs to model the services identified in the service plane. A means of achieving these two objectives is to consider them as two different aspects existing at the global functional plane: the capability view and the service view. Capability view One aspect of the

44、GFP identifies the individual SIBs and their discrete operations. These discrete operations contained within the SIBs can be combined to reflect the service features capabilities and facilitate the mapping of SIBs onto the Distributed Functional Plane (DFP) to help identify a comprehensive set of fu

45、nctional entity actions and information flows. STDoITU-T RECMN Q=1223-ENGL 1997 Y862591 Ob1i.5711 758 -7ma3m?smmWrxnm-.1-.I_._.- Element Service view The other aspect of the GFP describes the methodology and tools to combine the individual SIB operations to implement the benchmark services and servi

46、ce features. This aspect of the GFP applies the SIB modelling methodology to the individual services/service features. The operations and supporting data to model these individual services/service feature are specific to that service or service feature and therefore no mapping to the underling DFP i

49、 within an SIB relating to the SIBS capability. An SIB is a standard reusable network-wide capability consisting of SIB operations. A HLSIB is a combination of SIBs containing individual operations which may subsequently be combined with other HLSIBs or SIBs to create an even higher level SIB. A specialized SIB which provides the basic call connectivity capabilities. A service process is considered as a combination of SIBs (containing SIB operations) or HLSIBs that represent a discrete service activity. For the purpose of this Recommendati
